Booking date and time with a real person on the phone. Arrived when expected and carried out quickly and efficiently the job we wanted done. Thank you.

Excellent installation team! Lee, Jake and Molly were professional and courteous throughout the whole job. They were all very knowledgeable and very friendly. Great work done by all the team and tidying up as they go, also working around our cat and dog!

We’ve just had a complete new heating system and Air source heat pump installed and are really happy with the service we received. Will and Justin deserve a special mention as they installed the plumbing, radiators, ASHP and a new tank… they really are a credit to Synergi, they were polite, friendly and very efficient… nothing was too much trouble for them. Their work was so neat and they left the house tidy and clean each day. We couldn’t have asked for nicer people to do the work, they were a pleasure to have around. Once the heating system was up and running they took their time to explain all about it and set up the heating schedule on the app. As a result we now have a lovely warm home, we can highly recommend them.

We were recommended by another boiler company who felt our installation was too complex for them. From the first phone call everyone has been Professional, friendly, helpful and polite. The quote was good, we accepted and other than make cups of tea and the odd bacon sandwich we did nothing, all the crap cleared away, left spotlessly clean and tidy and the only way we knew that they'd upgraded the boiler was the house was warm 100% recommend them

Excellent group of plumbers. No matter who turned up they were always hard working and polite. Always kept us informed and it was a pleasure to watch skilled tradesmen who were at the top of their game (apprentice included). Would highly recommend

For the second year Synergy have serviced my boiler. Easy to organise with a 'real person' on the phone who was polite and organised. The engineer (Adam) who did the servicing was excellent. Quick, organised and efficient. What more can you ask? All in all a very professional service. Wish there were more firms around like this. Well done Synergy.

Just had an air source heat pump installed, Elliet, Molly & Ollie were a fantastic heating engineers (great people). They went out of their way to resolve any set up issues & answering any questions. We feel lucky to have had this team.

So thankful for the work to be carried out quickly when the existing boiler gave up! Not the easiest of jobs changing it but everything was explained as the job went on. Very happy with the work carried out by both Rich and his apprentice, even down to cleaning up afterwards. Thanks very much 😊

Great company to deal with. Efficient from quote to installation. Friendly and tidy installation. All round great service - Thank you SYNERGI.

Since I have been using Synergi SW Ltd, I have always been impressed with the professionalism of their staff. The engineers who have visited my property have been friendly, polite and have always told me what they are doing and why. When they have finished the work the engineers have cleaned up after themselves and tidied everything away. The office staff, when I need to contact them, are also very friendly and if they cannot answer your problem straight away then they get the answer/solution and ring back. I wouldn't use anyone else. Well done Synergi!

Another good experience with Synergy. They were responsive and competitive on price.

Dear Mr Gardner, I don’t normally take the time to write a review for the various services or products I buy, as I normally do my research and know what to expect, however, I feel compelled to write to you in this instance as your company, Hannah in particular went well over and above what I had expected when I contacted you regarding my boiler problem and subsequent replacement. Thank you and your team for a truly outstanding service!

Synergi are brilliant, had a boiler leak and they were on the scene within a few hours on a friday night. Excellent service and sorted the issue

As always a quick response time. Professional in every way. Friendly, polite & very helpful. Always explains everything to give an understanding of the work involved. I highly recommend Synergi to everyone. You just can't go wrong with these guys. Thank you to such a Friendly team. 👍😊

Terrible customer service and discourteous staff. Called company and advised £60 hrly rate only to be told later that they charge £90 for first hour. I advised for them to check back on the call records which they initially agreed they would, only for them to message 2 months later that they were unable to find the call records. How convenient! Then after another 2 months (completely out of the blue) they sent a threatening email for outstanding false invoice to be paid. Dreadful company with useless engineers. I would advise to avoid at all costs and choose a better company who treat their customers with better care

What a hidden gem of a company Richard and his team are fabulous . Company’s Now days are too quick to rip you off . I can’t thank this company enough They were quick to respond efficient and got my heating up and running in no time . 10 out of 10 service give them a try you won’t regret it . Well done Synergi .

The guys from Synergi did a great job. They turned up on time, covered carpets and cleaned up afterwards. Plus the job looked neat.

Giving one star because I can't give zero stars. Awaiting for a call back since 3/11 to talk to someone about the recent issue with my boiler. When initially installed in April an engineer checked that all was operational and we were happy that it was, I wish I could still say I was happy with both the product and the service. The communication with Synergi is poor, with promises to return calls not fulfilled. Richard is virtually impossible to contact when there is a problem although he was quick enough to visit and sell us the system! At the moment I am regretting the decision I made back in April to replace the boiler with them. There have been several problems including the latest issue. After installation we had to have another visit to fix a leaking radiator. Unfortunately we then had a much larger leak from one of the ancillary pieces attached to the new system which had to be replaced apparently due to a manufacturing defect in it. Fortunately we were only away visiting family for a few days as if it had been longer I think the ceiling would have collapsed! Fast forward to last month when we had several error codes on the boiler, which was not working at all. That seemed to mystify Synergi and was diagnosed as a possible printed circuit board problem and a Navien engineer was sub contracted to come out and replace the PCB. He made the decision not to do this and cleared the errors but he felt the pipework to remove the condensed water from the boiler was inadequate and in his opinion would back up and 'trip' the boiler. He would feed that back to Synergi SW He then left the boiler in the AUTO mode which should “take control” of the boiler and selects the best operating regime based on environmental conditions, external devices connected to the boiler and the performance required. It should constantly decides at which power level to operate based on the environmental conditions and the room temperature. This sounds fine but that was not what happened when the temperature dropped below the set value. The engineer who turned up 'resolved' this by putting it into the ON mode with no explanation why the AUTO mode was not operating as we'd expected. I'm not sure is the most efficient mode and I emailed Synergi for their comments on this as I feel the boiler should be working, with our thermostat in the auto mode. To add insult to injury the invoice I received stated "Upon investigation, found that the Navien engineer had set the boiler to Auto as per standard procedure, however homeowner wanted it on constant" That is certainly not correct, the engineer barely spoke to me, he certainly didn't give me any options and just changed the system to ON without any consultation. It took him all of 7 minutes and at no point did he explain why the AUTO setting was not working. I don't know where I go from here. I certainly object to having to pay for the visit and I have lost all confidence in both the boiler and the company and am still waiting for a phone call from someone, preferably Richard.

Covering Devon, Dorset and Somerset, but not our part of Somerset, smack in the middle. Currently new trained engineers for Somerset, or should I say my part of Somerset People shouldn’t be able to advertise this, and then say they don’t provide a service they say they do it’s a poor effort.

Excellent service, fixed previous issue as well as installing new boiler in good time. Left tidy work and cleaned up before leaving, highly reccomend!
