Jasmine Albano

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.

Alistair Hutchinson

What our customer say

I have always used Total Energy Services to for repair and maintenance to my property portfolio. I have found them to be reliable, friendly and helpful throughout and would not hesitate to recommend them.

Jonny Ralfe

Total Energy Services first came to our rescue some years ago when other heating companies were unable to fix our ancient oil boiler during a very cold spell, after weeks without heating waiting for engineers and spare parts which never materialised, we got in touch with Rob at Total Energy Services and within a few days our boiler was up and running again. Since then Total Energy Services have been our go to company for all things boiler and plumbing related. This summer they installed a brand new oil boiler for us which is now keeping us toasty warm. Their engineers are experienced and very knowledgeable and the response to our various requests have always been prompt and efficient. We highly recommend them as a company.

We moved to a Grade listed thatched house in April 2017. The house had old night storage heaters which we wanted to replace with another system. We contacted TES and duly made an appointment with Rob Lamb who spent a long time with us and after several visits we finally chose an oil fired system. A lot of thought was put into the planing in order to keep the boiler as far away from the thatch as possible and with their experience in listed buildings we felt comfortable to go ahead. The outcome was an all singing and dancing system with a combi boiler and enough hot water to cover 3 bathrooms. Their engineers were experienced, thoughtful as well as sympathetic to the look and the age of the house.
We would not hesitate to recommend them.
