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.

Join our happy Honiton households

“We were having trouble with our shower as the hot water output was very intermittent. We arranged a visit by Synergi SW Ltd based in Honiton. Very promptly from our enquiry John visited and diagnosed the fault and sourced us an excellent shower replacement. He also fitted a new garden tap and water softner meaning the glass shower door is now easier to keep clean. All is all very happy with visit and work carried out. I would certainly recommend Richard, John and the team for any boiler/plumbing issues that need fixing.”

Pauline, Honiton

I am very pleased with the services that was provided. Eden and Sam the engineers worked very hard – doing a complex and physical job. I had the old boiler removed and had a new boiler installed. It was a very good job with excellent pipe work using copper. I recommend synergi and I’m enjoying the cake that was given to me as part of the customer purchase.! I’ll make sure I service my new boiler yearly.

Sarah, Honiton

Richard was the third of three heating engineers I asked to look at a boiler that the Baxi engineer has said needed to be replaced and the only one who took the trouble to question that advice. He quickly found that in fact spares could be sourced and a repair was successful saving me a considerable amount of money. Throughout the process Richard and his team maintained great communication, worked very tidily (thank you Tyler) and left everything secure. I am very grateful to Synergi and would recommend them to anyone!
