The Synergi Price Match Promise


We won’t be beaten on value for our services. Our up-front pricing means the price we quote after your free home survey is the price you pay. There will be no hidden registration, waste removal or certification fees. For smaller jobs such as boiler servicing, fixing a leak, gas safety checks and emergencies you can view our price list here.

We promise to go above and beyond, providing real value from the start. Whether it’s a new boiler, solar technology or a shiny new bathroom, we’ll carry out a free in-depth technical survey so we can recommend the perfect products and services for your needs.

Many online-only heating and plumbing companies skip the survey process, so what initially seems like a cheap product may end up costing you more for in the long run. Similarly, their outsourcing of engineers means you might not get the full level of service and experience you were hoping for. We’re a local indpendent company here to take the stress out of big decisions and save you money.


We bet you won’t find a comparable package cheaper elsewhere. But if you do, we’ll match it!

Big enough to cope, small enough to care


As an independent plumbing and heating business we focus on providing a punctual, honest and professional service for our community. Our friendly team are courteous, clean and efficient – when we’re finished you’ll never know we were even there!

Established in 2014 Synergi SW started as a two-man team with a simple idea of building a plumbing & heating company like no other. Six years later Synergi is now a go to company for Devon, Dorset and Somerset.

Our team is built on local people, some of whom have worked their way up the ranks from an apprentice to fully qualified gas and oil engineers. We believe in continued training and developments for our engineers trusting their knowledge and skill set as our biggest asset. Our head office is based in the Blackdown Hills, a short drive from Cullompton.

Our satisfaction guarantee means we will never leave you disappointed. You’re in safe hands with us.


We hope to build a long-lasting professional service for our local area and beyond.

“Just had my boiler and radiators upgraded by the team at synergi, brilliant professional service, you wouldn’t even know they had been there, very clean and tidy.

Very pleased with my new efficient central heating especially the shower. Would definitely highly recommend Synergi.”


Recently had our new Worcester boiler installed by Synergi. The work was undertaken on time and without any mess! 

The engineer & his apprentice were both friendly and I was happy to have them in my home.


“We recently employed Richard to install a new boiler and couldn’t be more pleased with the efficient service we received the installation was carried out when promised and at reasonable price. Richard goes above and beyond to ensure that everything is satisfactory we wouldn’t hesitate in recommending him
