Synergi (SW) Limited

Had a gas hob installed by Synergi SW in 2020. Had another plumber check for leaks and they found the hob was leaking at the gas hob elbow. Took it off and found it had been installed cross threaded with water PTFE and had likely been leaking for years. I understand people make mistakes so, Contacted Synergi SW and just requested them to cover the cost. They did not care or offer any apology or cost for correcting their shoddy work, couldn't believe it! Don't trust this company or any work they complete!

First class service from Lewis and Ben very efficient always on time and considerat as I am a older lady, a excellent job done and a bit of banter i would highly recommend them.

Seemed like a good company at first. Can't fault the initial customer service and quote. However, my son arrived extremely prematurely (included in my email) so there was a delay in my response and after that radio silence. I sent three follow up emails to book in the works, to two different email addresses, and never heard back.

Just had Synergi fit a new heating system for my mother in laws property. Competitive quote, team friendly and the install team arrived bang on the time and date they booked! The installation was seamless the guys took pride in what they were doing and the system is working a treat. We didn’t feel sold too like some others and no pushy tactics so glad we used you, would highly recommend. White Cottage

Thank you very much to the Synergi (SW) Ltd team. We are always very happy with the service received and for the quick responses to requests for an engineer. Joe in particular deserves a special mention for solving and fixing several of our plumbing issues! Would highly recommend.

Have just said goodbye to Adam after he repaired my Vaillant boiler. I am very impressed with the Synergi experience and with the speed and efficiency shown by Adam and the other staff I have dealt with on the phone. Adam will be returning to repair a toilet cistern once the parts are in and it will be nice to see him again.

From first contact to installation

From first contact to installation, the team were incredibly helpful and clear, the pricing was reasonable and the team who came to put the boiler in were brilliant. They worked really hard, were clean and tidy and very polite, informative and respectful in our home. We can’t recommend them highly enough.

boiler service

I called up for a boiler service, synergi quickly booked me in, and gave me a two hour time window for the day of arrival. The engineer arrived and conducted the service without an issues. He was polite and very knowledgeable. I felt the price of the service and service I received was remarkable. Highly recommend

We had our new heating system installed from 23rd Feb 2026 to 27th Feb. The guys were Lewis and Ben who did the job. They were fantastic, punctual, professional, friendly, where you could ask questions They were happy to answer. We provided refreshments to keep them going. Jack did the wiring as well. Craig the fault finder was extremely efficient. Thank you guys.

The man who came out was brilliant

The man who came out was brilliant. He fixed both problems even though it meant him getting soaked. Highly recommended.
