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 Honiton 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 just 10 minutes from Honiton in Upottery. 

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.

“Our boiler was still working but very noisy,
Richard recommend a new boiler which is so quiet you can’t hear it coming on in the morning. Excellent service and price. I can highly recommend this company. Reliable, on time and tidy.”


We engaged Synergi SW limited based in Honiton to install some classic radiators at our flat in Sidmouth. From start to finish the engineers were polite and professional. The job was not straightforward, but they did a fantastic job at the quoted price. We have many years of experience with all kinds of trades people, having moved house many times and can say without hesitation that synergi are among the best. Would whole heartedly recommend them. Particular thanks to Will the supervisor and (same name) Will the installer who went the extra mile for us.


From initial contact to get an estimate through to completion, we couldn’t have asked for a better company.
Richard and his team are fantastic. Very friendly, knowledgeable and go beyond what I expected, explaining every step along the way and making sure your house is left clean afterwards.
We would thoroughly recommend Richard without hesitation. I know we will now use them for any future work that needs doing

See the Jurassic Coast

Sidmouth is home to a stretch of the Jurassic Coast World Heritage site, and you can see the distingishable red cliffs along the whole coastline. We think the views are best from Jacob’s Ladder (pictured).
