What Our Clients Say

In the twenty-five years Harvest Energy has been operating, we've worked hand-in-hand with many clients and have left lasting impressions on their homes and properties. Here are some of the most recent comments left by our happy customers.


I am really pleased with the outcome. Everything looks perfect and it gives me the extra space I needed. The team were fantastic, they were always there on time and there was no cleaning up to do after them. Their price was extremely competitive and the quality of work was exceptional, I will have no hesitation in using them in the future for smaller bits and pieces that I wish to get done.
A 10 out of 10 from me.

From the initial contact from the guys in harvest energy, right through to the end, the project was delivered on time and on budget. The project was managed by Colin Clare, together Colin and the architect I had decided to go with had exceeded all my expectations. It is because of this I would have no hesitation in recommending harvest energy in the future and have already done so.

The fittings look good, feel good and have improved the energy efficiency of the house.
The fitters were efficient, tidy, self-contained and well-disposed, in other words, professional.
Jason was easy to deal with, informative, polite and personable. They were great and I would recommend them as I would use them again in the future.
