About Duncan Renewables - Client Testimonials

  • Bespoke Furniture Maker goes Green

    "Since an initial conversation with a cold call company in October 2013, and after speaking to four independent companies (including a biomass consultant), who we felt could design and build a system for our needs, we decided to place our trust in Duncan Renewables and in June 2014 we placed an order. This decision was based on their team knowledge, past projects, approachability of the team, proximity to us and a competitive cost.

    Very soon after that, the project manager visited site and advised us on the part we agreed to play within the scheme which included alteration to existing buildings to create the boiler house, preparation and creating a concrete base to support the pellet store and the excavation of a trench to accommodate the district heating pipes. The work started on 28th July and was fully operational on 14th August. We have enjoyed the system for the past 3 months and it works extremely well, although over this period we have had no spells of cold weather.

    We have found all the team to be very helpful and good to deal with, from Sean in the beginning to Stuart and Gavin with the design. The installers, James and especially Matt, could not have done more to make sure the interruption to our business and home was carried out with minimum disruption. Thank you to Ben, the commissioning and service engineer, who we have had to call upon a couple of times regarding the simplest of troubles we have encountered and thanks also to Liam for your help and quick response to our emails regarding all the RHI queries etc. We would strongly recommended Duncan Renewables for your biomass heating system." - Andrew, Ben and Helen Conning, Butterfly Furniture
  • Showstopper Rooftop PV installation at AV Dawson Ltd, Middlesbrough

    “As a business with over 75 years of experience in the freight transport market we have always had a keen eye on fuel costs, but now, having significant warehousing and property portfolio, increasing energy charges have become a major cost to the business. As such we made a strategic decision to regain some degree of control of our electricity bills. Through contacts in agricultural circles I became aware of Duncan Renewables, and, following due diligence in the market and with the financial institutions who would be part funding an installation, we asked them to advise on suitability options. With over 1m sq ft of warehousing, several potential schemes were proposed and we chose a 240kWh array on our fabrication halls. These are where the majority of power is consumed, therefore offering the best return on investment. We did price the scheme with an alternative supplier, but the combination of professionalism, price and a site visit to a significant installation led us to proceed with Duncan Renewables.

    This scheme had particular challenges, not least because the roof was at a height of almost 50m, but because fabrication was on-going in the space below. Duncan Renewables worked alongside our sheeting contractor to ensure a safe and efficient installation sharing access, cranes and fall prevention systems to reduce cost. Alongside the on-site activity, Duncan Renewables’ administrative team took care of all the registration paperwork and the connection agreement with the local DNO leaving us to get on with running our business. The installation was commissioned in June and by mid -July had generated 46,000kWh. We have been blessed with sunny conditions and it’s very satisfying to think that we are taking full advantage.” - Gary Dawson, AV Dawson Ltd
  • A previous client now has both Biomass and PV

    "This is the second time we have used Duncan Renewables. The first time was to fit solar panels and now our woodchip boiler. We needed to install central heating which was done efficiently and considerately. All the workmen, plumbers, electricians, fitters and joiners were professional, hard working, pleasant, respectful and very capable. They gave us a good resume of each days progress and future plans. They kept us informed of how the installation was going. We recieved comprehensive training on how to use the boiler. We would definitely recommend them to other people for either solar panels or wood chip installation." - Mr Clayton, Ulleskelf
  • Our latest happy domestic solar PV customer

    "On a visit to the Duncan Renewables premises for information, I found the staff to be very helpful and provided all the information I needed. A site survey was done and Michael was again very helpful. I received my quote within 3 days. My installation was on time and both the installation team and electrician were excellent and friendly. Next step was the EPC survey which was performed quickly. Overall the whole job and team were excellent. Thank you for providing a great service, on time, in the price quoted with no hard sell or gimmicks - a refreshing change in today's world! (Done the way I like to run my business and deal with customers)." - Mr Holt, Ripon
  • Pig farm benefits from Biomass providing hot water for commercial cleaning

    “The Duncan Renewables team designed a bespoke package to combine hot water for power washing the pig buildings as well as heating the farmhouse. The installation involved many man hours in and out of pens full of pigs which the Duncan staff completed without any fuss or complaints in far from perfect conditions! The quality of the workmanship in the boiler room and associated pellet store is of the highest standard. The workmen were extremely helpful, polite and very clean and tidy. We are now able to wash pig pens out in a shorter time and we are very happy to recommend Duncan Renewables.” - James Sanderson, Morton Grange Farm
  • Goldsborough Hall says goodbye Victorian coal boiler, hello new Biomass boiler

    “We chose Duncan Renewables as they are not only a well established local family firm, but also experts at installing the finest Austrian Guntamatic boilers.

    Their experienced professional team worked miracles to convert our old underground Victorian coal boiler house to install 2× 100kW boilers, 2× 1500ltr buffer tanks and 15 ton pellet store, all fully automated and remotely monitored, supplying constant heat to the Hall for central heating and hot water.

    The best part of all is the Government’s 20 year Renewable Heat Incentive – the install will be paid for within a few years, then heating the Hall will potentially be a neutral cost for the rest of the 20 year agreement.” - Mark Oglesby, Goldsborough Hall
  • Local Golf Club hits a hole in one with a new biomass boiler

    "Selby Golf Club had been tracking the cost of oil over the last three years whilst also considering alternative fuel options. The Government's Renewable Heat Incentive Scheme for commercial premises hastened their decision making in 2013.

    One of the Selby members works closely with Duncan Renewables and introduced them to us. The Club asked for detailed tenders from a number of potential suppliers and preferred the “one stop option” that Duncan Renewables were able to offer.

    The delivery and installation of the biomass boilers went extremely well with the team from Duncan Renewables working well within the agreed time frames.

    The anticipated savings to the Club over the long term supported by the Renewable Heat Incentive payments will help to drive the long term vision for Selby Club." - Sally McHale, Club Secretary, Selby Golf Club
  • Yorkshire Dales Outdoor Centre goes Green

    "Low Mill has an ethos about using the outdoors in a sensitive manner and helping educate participants about the need to be responsible for our environment. When it became clear we would need to replace our original oil boiler from 1976 I didn’t want to just replace it with another oil system, there had to be a more sustainable alternative both from a “green” perspective and financially for the charity. With the oil price rising exponentially, budget was a concern particularly as Low Mill is an independent charitable trust so the significant saving on fuel and the RHI offered a very real income incentive.

    We chose Duncan Renewables over their competitors for their commitment to our project. The whole time they were honest and open, some other companies’ figures didn’t quite stack up and we were concerned that they could be over promising. Duncan Renewables took considered time over this and worked very closely with us to make sure they could put the best options in front of us. They walked through the whole process with us including the planning application, we felt like a partnership not just a customer. The installation was carried out during the winter down time, the Duncan Renewables team didn’t leave us until everything was 100% and they did a lot more “downstream” work than we first thought would be necessary. It is this level of support and continued care that we value.

    We are receiving some very positive feedback from our clients who have commented that the building is warmer, with the reduced fuel costs we can afford to run the heating for longer during the day. We were also having problems when clients returned from sessions and thirty people tried to all have showers at the same time, the new installation and work by the Duncan Renewables plumbers has solved that issue. Even without the RHI I am confident that over the next twenty years Low Mill will continue to make significant fuel cost savings each year and with the satisfaction that we are doing so in an environmentally sustainable way." - Terry Hailwood, Low Mill Outdoor Centre, Askrigg
  • 100kW Biomass and 50kW Solar PV help power low impact office complex

    "From acceptance to completion of my biomass and solar system, I have been highly impressed by the professionalism and quality of service given by the Duncan Renewables team. After being given several quotes by other companies, Stuart and Mark Duncan ensured that my every question was answered; prompt answering of the telephone when I had a query was a distinct and noticeable bonus to their service, also their vast previous installation experience. In addition, they provided me with a top quality boiler and back up that was unrivalled. Wireless 24 hour monitoring of the system ensures that the system runs efficiently and without hiccup, along with the added bonus of a 5 year warranty. Peter and Liam, who ran the project seamlessly, are a credit to the company ensuring customer satisfaction was top priority. The solar team were highly aware of potential disturbances of tenants during office hours. Members of the team were always neatly presented and friendly. I therefore would highly recommend the services provided by Duncan Renewables and would like to extend my sincere thanks to the team for your excellent service. I look forward to future dealings with Stuart and Mark at Hareland Courtyard Offices." - Barry Pittaway, Harelands Courtyard Offices
  • 250kW of Biomass Boilers installed throughout Hackthorn Village

    "Hackthorn is an agricultural estate and has been growing biomass in the form of miscanthus for some years. We were looking for a way to use this for our own heat use, and wanted to have the convenience and automation that only pellets can deliver. We certainly did not want to be slaves to the boiler. To achieve this we have found the perfect solution in Terravesta's Grower Fuel Loop, where Terravesta buy our miscanthus, and supply us back our heat requirement as miscanthus pellet, the Guntamatic Biocom boiler, which is a miscanthus capable pellet boiler, and Duncan Renewables, a brilliant heating engineering business capable of designing and installing the most efficient district heating systems. Duncan Renewables' engineering design and experience has been essential to the success of the installations. We have two of three district heating schemes installed and working at Hackthorn, and look forward to the third coming on line shortly. The miscanthus pellets are burning well, and are supplied on a 10 year forward contract linked to RPI. Who else can offer that level of fuel price security?" - William Cracroft-Eley, Hackthorn Hall
  • 100kW of FREE BIOMASS in Reeth

    "We would like to thank Duncan Renewables for providing us with a FREE biomass boiler to heat our hotel. We were experiencing increasingly high oil bills, which were only set to rise, so it seemed sensible to switch to biomass. With the Duncan Renewables offer we had no capital to outlay and will benefit from reduced fuel bills and free servicing. The team were polite, hardworking, knowledgeable and worked with us to ensure there was minimal disruption to our business while the work was underway. They left the job clean and tidy and we would recommend them to anyone looking to reduce their heating bills." - Mo Usman, The Burgoyne Hotel, Reeth
  • Rural B&B with holiday cottages heated by 100kW biomass system

    "From the very outset we were reassured by the professionalism and knowledge we encountered at every meeting with various members of their team. Our every query was met and every problem overcome and work soon commenced on the project. Despite the work being undertaken during hot summer months and throughout our busy trading season, disruption to our visitors was minimal which was one of our main priorities. The team of workers were amazing - they were punctual, polite, clean and tidy and of course a highly experienced workforce, we can't praise them enough. The project was completed on schedule and on budget and we now have a heating system throughout our whole property which is fully controllable, highly efficient, clean, quiet and also green with masses of hot water to supply our every need. We can't thank Duncan Renewables enough and would highly recommend this company to anyone seeking a renewable energy heating system." - Dirk Pittaway, Mount Pleasant Farm
  • Private Estate heated by district heating Biomass system

    “We were very pleased with the level of service from Duncan Renewables from the initial quotation to installation of the boiler. The conversion of one of our existing buildings and the laying of the district heating was well planned and communicated meaning minimal disruption to the estate. The RHI application process has been supported by the head office team throughout. We wouldn’t hesitate to recommend Duncan Renewables or the technology to anyone considering it.” - Estate Owner,
  • Several self catering cottages heated by 100kW district biomass system

    “Following 6 months researching the feasibility of biomass to heat 2 houses and 4 cottages at South House Farm, we came across Duncan Renewables. We’d previously visited other competitor installations and Duncan Renewables invited us to view one of their installations similar to our project. We were impressed by Stuart Duncan, his depth of knowledge of the system he was selling, his thoughts on what should be avoided and how the whole installation would work. It was refreshing to find someone who had hands on experience and was confident enough in his design to guarantee the whole system. We agreed a price and time scale to fit in with our business. The job was completed in a fortnight by excellent staff and the system was commissioned on time. It is still early days but the biomass boiler is working beautifully. We are still collecting data but the system seems to be performing as predicted. It is reassuring to know that Duncan Renewables are only ever a telephone call away with a 24 hour back up.” - Ken Pattinson, South House Farm, nr Robin Hood's Bay
  • 100kW district Biomass system heating a stunning rural wedding venue

    “Fantastic service throughout the whole installation progress. I have recommended Duncan Renewables to anyone who will listen. The boiler performs beyond my expectations, which were high to start with. The heat output is amazing with endless hot water for my hot tubs and business. Our bistro has never been so warm and cosy the only down side is our log fire is now redundant!“ - Jackie Wray, Whinstone View Bistro and Lodges, Great Ayton
  • 245kW On-Roof Commercial Solar PV System

    “Operating in a sustainable way is very important to us. Being a year round exhibition centre we have a significant electricity requirement and installing solar panels was an obvious step we could take to reduce both our costs and our carbon footprint. The scale of the project was somewhat daunting but Duncan Renewables has done a first class job in managing the installation from the initial planning permission application right through to registering the system with OFGEM. Due to the number of events we hold here, there was a narrow window within which to complete the project but the team from Duncan Renewables worked efficiently to ensure that the system is up and running in time for The Great Yorkshire Show. We are delighted with the end result and look forward to enjoying the benefits over the next 25 years”.

    - Nigel Pulling, Chief Executive of The Yorkshire Agricultural Society
  • 100kW Biomass Boiler

    “We spent two years researching and enquiring about biomass boiler installations and suitability for our hotel. We eventually sourced four companies to do site inspections and provide detailed quotes. Duncan Renewables provided the most detailed site inspection and answered all our queries. They also came highly recommended by a satisfied customer who owned a hotel in Bridlington, and this testimonial finally enabled us to choose Duncan Renewables over other companies – even though the latter provided cheaper quotes. Like most things in life - you get what you pay for. The quality of materials, attention to detail and standard of workmanship is exemplary. We used LPG before but the new boiler has enabled us to provide a warmer and more comfortable environment for our guests.”

    - Gary Nowell, The Old Mill
  • 198kW Biomass Boiler

    "We are extremely pleased with the installation Duncan Renewables have completed. They completed on time and budget, even with a few client changes along the way. Nothing was a problem. We would definitely recommend them to anyone looking for a high quality product and installation that will work with little time input on a day to day basis."

    - Richard Barker, Managing Director of Hill Cross Furniture
  • 100kW Wood Chip Boiler

    "From start to finish we found the installation of the system ran very smoothly and there were no questions or queries that we had that Duncan Renewables couldn't resolve. We look forward to the next holiday season running on green energy."

    - Ed Hitchen, Woodhouse Farm Holiday Home and Caravan Park
  • 100kW Wood Pellet Boiler

    “As part of our ongoing commitment to sustainability, the installation of a Biomass Heating system has very much been at the core of our development plans for Thorney How along with Electric Car charging points and Electric bike hire. Duncan Renewables have been an enormous help in identifying the best solution for a rambling Grade 2 listed property with accommodation split over two buildings and the requirements of the backpackers, walkers and groups that stay with us. Installation work has so far been faultless with considerate and communicative staff. We are looking forward to the system being commissioned any day soon on schedule and in time for our first wedding at Thorney How in a few weeks time.”

    - Taylor Nuttall, Owner of Thorney How Independent Hostel, Grasmere
  • 99.9 kW On-Roof Commercial Solar PV System

    "Our feed mill has an enormous requirement for power, so reducing our reliance on carbon based energy was, and still will be, a great priority for us. Having a huge area of redundant roof space also seemed to be a wasted asset and once the Government brought in the Feed-in tariff, fitting a PV system to the roof seemed to be the logical conclusion. We knew that beating the 1st August deadline was always going to be tough, and missing it would have reduced the return from the system, so we needed a contractor who had experience, but more importantly had plenty of skilled manpower….. they have been professional from the outset, have been responsive to all our concerns and shown great awareness of our priority to our customers and for health and safety while working on our busy site."

    - Graham Jameson, WE Jameson & Son Ltd,
  • 100 kW Guntamatic Biomass System

    “The Guntamatic Biocom boiler will help us make significant savings compared to the oil heating system we were previously using. The boiler has been reliable, has only needed minor adjustments since its installation, and has helped us to provide a comfortable environment, not only for ourselves, but more importantly for our guests.”

    - Mr & Mrs Goddard, Owners - Marton Grange Country House,
  • 49.91kW On-Roof Commercial Solar PV System

    "As a Charity, relying almost entirely on charitable donations, reducing costs wherever we can is vital. In addition to this, we are keen to contribute to reducing our carbon footprint. The installation of solar panels has helped us do both. When we started looking at the feasibility of solar panels, Duncan Renewables provided invaluable help with their indepth knowledge and un-biased advice. When the decision was made to go ahead, they managed everything in relation to planning and registration of the system. Due to the nature of the work at Martin House, the installation needed to be carried out within a short space of time with as little intrusion as possible and this was done extremely well. We are very pleased with the result and look forward to the savings we will make on our electricity and the additional income from the tariff".

    - Aase Somerscale, Director of Business & Support Services - Martin House Children's Hospice
  • 4.00 kWp On-Roof Domestic Solar PV System

    "We found Duncan Renewables to be knowledgeable and reliable, the quotation was well explained. Communication was excellent, they turned up when they said they would and the installation was quick and effortless with no inconvenience.

    - Mrs. B in Little Ouseburn,

  • 3.99 kW On-Roof Solar PV System

    - Mr. G at York,
  • 3.84 kW On-Roof Domestic Solar PV System

    "If only every company was as helpful…Excellent service from start to finish, over the phone especially. All “workmen” involved were so helpful, and clean. I’m so used to having to clean up after having work done but I didn’t have anything to do! I wouldn’t hesitate to recommend you to anybody, keep up the good work!"

    - Mrs. C at Draymans Field Farm,
  • 3.84 kWp On-Roof Domestic Solar PV System

    "I have found your organization very professional and pleasant to deal with at all levels. The installation proceeded without a hitch in all a very satisfactory commercial experience.

    I will have no hesitation in recommending your services to others."

    - Mr. B in Skipton,
  • 3.76 kW On-Roof Solar PV System

    - Mr. S at Yeadon,
  • 3.76 kWp On-Roof Domestic Solar PV System

    "From the initial contact with the company, we found the whole experience professional. The representative gave us full details of the system and what was to be expected of it, along with timetable of events. The timetable was adhered to and all the work carried out neatly and efficiently. The installers were polite and prepared to explain all that was going on."

    - Mr. & Mrs. W in Marton Cum Grafton,

    - Mr. B at Whitwell Farm,

  • 3.00 kW On-Roof Domestic Solar PV System

    - Mr. L at Northallerton,
  • 2.52 kW On-Roof Domestic Solar PV System

    "We experienced an excellent service from Duncan Renewables. They worked hard to find the most appropriate design installation for our home. We were never over-promised the financial benefits and the calculations for return on capital have proved realistic and reliable. We always felt that Duncan Renewables would rather retain their business reputation for integrity before over selling to us. We received a prompt, reliable, and neat installation which met our exact requirements. The installation team were courteous, knowledgeable, and willing to explain everything in detail. The system has delivered beyond expectations and we certainly feel that we have made a sensible financial decision – and we are proudly doing our bit for the environment into the bargain. There are no catches; the current Feed-in-Tariffs really are as attractive as they seem and we would urge more people to make the investment and share he benefits which are contracted for 25 years and indexed linked.
    Where else could you currently get such a guaranteed rate of return on your capital?"

    - Mr. P in Harrogate,
  • 2.22 kW On-Roof Domestic Solar PV System

    "We are very, very pleased with the PV Solar Panels supplied and fitted by Duncan Renewables . From the very first telephone call through to the handover, we have found the staff at Duncan Renewables to be very efficient. Polite, & knowledgeable. – It has been a pleasure and we are so pleased to have Duncan doing the work. [Jovana] is so friendly and polite on the phone and very knowledgeable about the system. Nigel explained the system fully in a way we could understand and did not pressurize us at all into having a system fitted. The installation team were excellent, leaving everything in a clean & tidy condition. The electrician was excellent – a competent, tidy worker.

    The results: a system which appears to be working brilliantly."

    - Mr. & Mrs. A in Knaresborough,
  • 2.00kW On-Roof Domestic Solar PV System

    "A first class service from start to finish. From making the panel choice through to assistance in completion of the FiT Application Form, nothing was too much trouble. And the price was competitive too."

    - Mr. E in Thirsk,
  • On-Roof Domestic Solar Thermal Flat Plate System

    "We had Solar panelling fitted to the roof of our house last October including Solar thermal for hot water. The fitting team from Duncan’s were efficient, knowledgeable, speedy and I am pleased to say no mess or disruption to me or my wife. I am also very pleased with the result which is earning us money on a daily basis which is welcome in these times of escalating fuel bills. As a result of my installation three further neighbours have had it fitted by Duncan’s.

    I have no hesitation in recommending this professional company."

    - Mr. B in Bramham,
  • On-Roof Domestic Solar Thermal Flat Plate System

    "Our solar PV panels were installed on our small south facing roof during the build process of our new build house. Duncan Renewables were able to plan the installation so that the various stages were completed to fit around the builder’s requirements. Inside the house the other parts of the installation take up the space of a single full height cupboard. The only noise is a quiet hum which tells us that the solar thermal panels are making us free hot water. From the planning of the system to commissioning the panels Duncan Renewables were very helpful, keeping us informed throughout. Their workmen were courteous and tidy at all times"

    - Mrs. R in Kirk Deighton,
