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.

“Excellent service, prompt and go beyond the call of duty. Have used personally and with our business property and never had an issue. Thoroughly recommend”


Excellent customer service – responded immediately to my plea for help on social media when I lost my heating and hot water and even called back to check I had gotten my boiler back up and running. Given that we are working from home and homeschooling this help and support was very much appreciated. Thank you!


Synergi kindly came out on the day when we had a major boiler leak problem, although we are not regular customers. They were friendly and knowledgeable, helped us out when we needed it desperately and the service and follow-up was excellent. Highly recommended.
