Thinking of getting an Air source Heat Pump?
While gas boilers typically have an efficiency rating of around 90%, the average heat pump has a rating of 300%+.
On average, you could save £590 per year* on your fuel bill when you replace an old G-rated gas boiler with an air source heat pump.

Quality Boilers
We only install boilers from industry leading manufacturers. The Worcester Bosch boilers were rated Which? Best Buy for quality and reliability in September 2019.
Local and Independent
Big enough to cope and small enough to care. Our team is built on local people, with their skill set being our biggest asset. You’ll find our HQ in Honiton but our engineers are based all over the South West.
Finance Available
Spread the cost of your new boiler over 24 months at just 0% APR or over 120 months at 7.9% APR. We’ll help you find the right boiler at the right price.
Fast Installation
Have an emergency? We understand how distressing it can be without heating or hot water. We can usually install a new boiler within 48 hours from start to finish. Just let us know if it’s urgent.

“Richard was so professional, he talked us through every aspect of having new boiler and flue fitted, giving great advice and guidance. When fitting boiler both Rich and Will were iso respectful of my home and made sure I was informed every step of the way. To be honest you really wouldn’t have known they had even been here as everything was cleaned and put back exactly how they found it!
Local lads providing a faultless service! Would have no hesitation in recommending.”

“Just had Synergi fit a new heating system for my mother in laws property. Competitive quote, team friendly and the install team arrived bang on the time and date they booked!
The installation was seamless the guys took pride in what they were doing and the system is working a treat. We didn’t feel sold too like some others and no pushy tactics so glad we used you, would highly recommend.”
Simon Drury
“Wayne, Molly and the team installed our ASHP over a two week period. They were hard working, professional and took time to keep us posted on everything that was happening as we weren’t always on site. On arrival we needed to finalise the position of the pump and the hot water tank and Wayne talked us through the various options to find the best solution. Wayne also noted that one of the radiators was going to look out of size in the room and worked out an alternative arrangement for us which was much better aesthetically.”
