What our customers say

Total Energy Services have carried out various works for me including oil boiler servicing and emergency work to clear a blockage in my hot water system. On all occasions the engineers have been friendly and polite. They also take the time to explain what work they are doing and why. They are a highly efficient company which I highly recommend.

Kevin Neale

We had a new boiler fitted after a very thorough inspection. An excellent team arrived on the date arranged and were punctual and very helpful throughout their three days of work. The final bill was as per the initial estimate and we received a detailed briefing at the end of the work programme.

Sarah East

My old oil boiler finally gave up and after 3 quotes I went with Total Energy who were not the cheapest but gave me confidence in their ability, and the final bill was less than the quote despite alterations to the roof and flue. A new boiler was in and working in 2 and a bit days. Utility room left clean and tidy - wouldn't know they'd been in. Excellent service and can certainly recommend.
