Delta T Eco Heating Systems Reviews 

Thank you Delta T, we are so pleased with our new Heat Pump, all the staff were friendly, professional and a pleasure to deal with.
The communications and messages to alert arrival were very helpful
We would recommend Delta T Heating !

We used Delta T to install a heat pump in our house. This involved removing our old gas boiler and installing new plumbing and electrics. The experience could not have been better from start to finish. Charlie (Technical Director) was generous with advice and information and discussions with our local authority even before we had decided to go ahead with them, and all our questions were answered clearly and promptly. The team of plumbers and electrician who did the installation were a delight, and explained everything beautifully. They were with us for some time but were always considerate and left the works clean and orderly at the end of every day. Communications were always clear and helpful. We are absolutely delighted with the new system which kept us beautifully warm in cold Spring weather. We rwarmly ecommend Delta Eco Heating systems.

Great company. Can highly recommend for planning and installing air source heat pump, very knowledgeable and great workmanship. Recently had the air source heat pump annual service and again great professional service. Excellent communication and all queries answered

Delta T Eco Heating Systems installed our Air Source Heat pump in Jan. 2024 and they did a fantastic job. We then had them back to do the annual service as well. The team at Delta T are professional, knowledgeable, friendly, responsive and on time for appointments. We highly recommend Delta T and their team and will continue to use them for all our heating needs. Thank you Charlie, Chester and Becci for the outstanding service.

From initial detailed house survey for heating requirements to fully explained quotation to installation of the appropriately sized heat pump, Delta T have been really excellent.
As the house is quite old, several radiators needed to be replaced to increase output efficiency and this was done efficiently, prior to installation of and plumbing in the heat pump. The Delta T installers were most professional and the whole job was planned and implemented with impressive care and attention.
I’ve enjoyed 6 weeks of a warm house at 18C (can easily be adjusted) and constant hot water, all at lower cost off-peak electricity.
I can recommend Delta T not only to do an excellent job, but importantly to ensure the most appropriately sized heat pump and radiators are installed to achieve the optimal result.
Definitely a very satisfied customer!

Delta T installed a heat pump for me, in October 2024. They did a very efficient job. Helpful and considerate too. I love my heat pump.

Delta handled our change from old electric storage heaters to a new air-pump heating system.

Our house is circa 1925 and small and cluttered, so the job was never going to be easy! However the engineers from Delta were very knowledgeable, pleasant, professional and handled everything in their stride. Any issues that I flagged (which were few) were handled very quickly.

Really *very* happy with the work and how friendly and professional the team were! Great bunch of guys!

Delta T provided a clear survey and efficient installation service.

Unlike most of the installers we contacted, they spent a lot of time explaining how Air Source Heat Pumps worked before asking us to confirm our order.

The trades people who installed the system were exceptional both in the quality of the work and the way they respected our home.

We now have a new and effective heating and hot water system.

Trustworthy, local group of young men. Very knowledgeable about heat pump installations - (Heat Geek certified which impressed me) they installed our underfloor heating and swapped radiators over very neatly. They dovetailed in with the builders working on our house and I trust their competence and highly rate their attention to detail. We are very very pleased with our heat pump.

We were worried about needing help and service for our heat-pump setup. Delta-T responded *very* fast, they *really* know what they are doing, and charges are reasonable.

Delta T is an enthusiastic, knowledgable team of heating engineers who did a quality job for us. They also took great care to ensure our air source heat pump was optimised for our radiator-based heating system. After the installation, I was initially anxious it might not work but almost one year later, I now have clear evidence showing our house is warm and the system has cut our heating CO2 by around 70% for about the same running cost as our old oil boiler. Amazing. If your boiler needs replacing, seriously consider this as a viable option.
