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!

small enough to care

“Richard was so professional, he talked us through every aspect of having new boiler and flue fitted, giving great advice and guidance. When fitting boiler both Rich and Will were iso respectful of my home and made sure I was informed every step of the way. To be honest you really wouldn’t have known they had even been here as everything was cleaned and put back exactly how they found it!?Local lads providing a faultless service!?Would have no hesitation in recommending.”

Vicki England

“Both big tasks and small carried out promptly. We have used Synergi for big plumbing jobs, including to respond to major plumbing emergencies, and for small jobs replacing tap washers and repairing small leaks. The service has been prompt, professional, and each time a tidy job was done even when carpets and floorboards had to be removed and replaced. Definitely recommended.”

John Taysom

“We have used a number of local plumbing and heating firms over the years and none of them come close to the service we have received from Richard and his team at Synergi SW Ltd. We have used them a few times now so I know the level of excellent customer service is no fluke and they are consistent with their approach. You will get polite professional tradesmen who turn up on time when they say they will, confidence that the job has been done to a high standard all at a very competitive price. What more could you ask for, we won?t go anywhere else.”
