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 just 15 minutes from Exeter in Honiton.

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.

We have instructed Synergi (SW) Ltd to carry out annual gas and oil servicing on many of our properties in the Exeter and East Devon area as well as undertaking boiler replacements and other reactive plumbing & central heating works as required. They consistently provide an excellent service and react swiftly in an emergency. I have no hesitation in recommending them to anyone looking for a reliable, trustworthy and professional company.”

Mark Lewis

“I’m a small business owner in Exeter and I cannot afford to have breakdowns – the Synergi team were out within an hour of me calling them and fixed the job professionally cleanly and tidily. Since then I have taken them on a long term basis and cannot fault them, highly recommend.”

Tim Wigram

“Fantastic service, our boiler went kaput and Richard was easy to deal with, concise in his estimate so we didn’t get confused, and went out of his way to get it installed quickly for the sake of our young daughter.

Will definitely use them from now on.”
