Please Excuse the Kettle


We are delighted with the benefits we are getting from the ground source heat pump system installed by Keith Bentley and his team at our home. Keith provided a thoroughly professional and skilled service. Nothing was too much effort for him and his team and their pride in their work and in producing a great system shone through. We could not have asked for more from them.

We have recently finished a barn development which has ground source heating in each unit. After much discussion we decided to go for a district system this is when we were fortunate enough to be put in touch with Keith Bentley at Bentley Renewables.  A district as I discovered is very complex but Keith was in his stride. Every eventuality we came up against was dealt with, with a pragmatic approach enabling us to achieve our end goal. Throughout the project Keith had access to specialist data enabling us to maximise the efficiency of our unit. Keith was always on hand to deal with queries from the builders and fitted with the builders schedules.  Once the insulation was completed Keith and Marie were extremely helpful in the RHI accreditation process. Should we do another such project Bentley Renewables would be our first port of call.

Dear Sir/Madam

Re: Keith Bentley

I was introduced to Keith Bentley approximately three years ago as a plumber, but with specialist knowledge in underfloor heating systems and more particularly ground source heat pumps and their systems.

He undertook and extensive plumbing and refurbishment scheme on Hill House and incorporated within that a state-of-the-art ground source system, which i believe to be installed to a high specification and to an extremely high standard.

I am a Fellow of The Royal Institution of Chartered Surveyors and have been practising as a Rural Surveyor for almost 40 years.

Keith Bentley has, on every occasion that i have met him, been exemplary in the way he has handled business and technical matters and without hesitation i would be happy to recommend his expertise in his own particular field.

I have indicated that i would be happy for any of his potential clients to view the installation at Hill House, which to a very large extent speaks for itself.

Yours Faithfully,

Dear Keith,
Thank you very much for successfully concluding the installation of my ground source heat pump. Prior to selecting you as the contractor, I interviewed 5 or 6 others but even with my limited knowledge, I quickly realised that I knew more than they did…which was not a good sign. However, your proposal was clear and easy to understand and you knew how to use the land to the best effect.
The installation commenced in December and I was impressed at how, even in the most inclement weather, you were there every day, up to your shoulders in mud! It was bitterly cold, but even so, the work continued under lights from the digger or just in darkness anyway. The land was reinstated after the digging and the site was left tidy.

The workmanship on the pipework is incredible and the use of high quality copper and brass fittings stands out. You eschew plastic hoses and the job looks all the better as a result. I am in the refrigeration and AC industry myself and I recognise the quality of the workmanship and also the use of premium quality pumps and components. The circulation pumps (of which there are many) are themselves the most energy efficient on the market, but this is largely unseen. It would be easy for you to cut corners on the components but you have used the best on the market throughout.

It is a little too early for me to comment upon the running cost savings but I have no doubt that they will be in evidence and everything is working perfectly so far, 6 months in. The post-installation follow up has been excellent and it is great to have personal service from somebody whom I feel that can be relied upon.
Thanks for doing a great job, and I am delighted to recommend your expert services.

 Kind regards,

Keith Bentley has just completed the installation of my ground source heating system. The new central heating system exceeds all expectations. The array of pipework and parts which make up the engine of the operation have been very carefully connected so that they look stunning. His attention to detail has been excellent.


It has only been a few weeks since the installation and visitors all comment very positively about ‘the still’ in the utility room. The boiler is very quiet which is far better than anticipated. We made several changes which were all accommodated with good humour. Keith and Steve work to a very high standard and left everything very clean and tidy. I am very happy to recommend them.
