Synergi SW Ltd Avis 

As always, Synergi provided their usual 1st class service for my annual boiler service. The Warm Cover policy is excellent value for money!

A really first class installation of a solar PV system completed on time and on budget

Oliver our attending engineer this morning was a fine Ambassador, smart, attentive, knowledgeable, communicative providing service with a smile, very professional and polite, thank you.🫡👍😃

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, 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.

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. He fixed both problems even though it meant him getting soaked. Highly recommended.

Helpful and friendly got on with work. Very pleasant young man.
Wouldn't hesitate to recommend Synergi SW.

I just wanted to say a heartfelt thank you to my social housing provider and the contractor who carried out our air source heating upgrade. Synergi SW Ltd made me feel comfortable and at ease as soon as they arrived at my home, everyone I interacted with was friendly, helpful, and clearly took pride in what they were doing. The new system has made my home so much more comfortable, and I really appreciate the effort that went into making this happen. Special credit to Jordan and Molly, I don’t think Jordan had a hot cup of tea the whole time he was here as he just wouldn’t stop working!

What a great experience we had.. from Tyler doing the survey to Molly and Justin doing the install! We had a full central heating system installed after moving into a house with storage heaters. The guys were so respectful of our home, and did a first class job!

I have used Synergi for many years and can recommend them without any hesitation, their engineers are experienced, helpful & polite and deal with any issues efficiently. Their office staff are equally efficient and go that extra mile to make sure any repairs are scheduled quickly. I recently had a boiler breakdown and they attended and dealt with the problem within hours!

A new heating/hot water system was fitted in my flat by Wayne and Steve. They were professional, respectful, and made sure everywhere was clean and tidy each day when they left. Everything was explained well and I’m now toasty and warm. These guys are an asset to your business (even though they laughed until nearly crying when I got stuck in my recliner chair when the power went off briefly). All in all, a fantastic job!!

Workers always helpful and professional. Neat and tidy turn up on time and are quick and efficient. Always do a first class job.

Engineer always arrives promptly, is efficient and helpful. Since the ASHP service we are already seeing a significant daily saving to our running costs, due to the unit being misconfigured.

The guys that came out to install a completely new ASHP, were absolutely brilliant!! They were so understanding especially of my kids who have additional needs and were very respectful of my home. They always made sure to keep me updated on everything going on. Absolutely amazing, Definitely recommend these guys! 😁

Synergy is just the best to look after your boiler & radiators. Their engineers are absolutely excellent and friendly. It was the best decision we ever made when we left British Gas because of the cost increases.

Fitted us in to a busy schedule to get our boiler back up and running. Very prompt and friendly also very professional. Glad we have found them

The guys who came were brilliant, really thorough and made sure we understood everything! Any issues we’ve had, the company has been helpful and prompt in helping us out

Lovely service, professional and friendly staff! On time, and an easy process from start to finish. We always use Synergi for this reason. Tash was really helpful when reminding us we needed to book for our annual service and booking was straight forward. Adam who did the service, and has done before, is friendly and efficient. 100% recommended!
