Synergi SW Ltd Avis 

Good service, friendly, arrived on time and service done with no issues.

In an area with very hard water we are constantly replacing irons, kettles, mixer bars, taps ... The Synergi engineer suggested fitting a Combimate to soften our household water. They fitted it with minimum fuss and were professional, polite and friendly. They also explained carefully how to replace the phosballs annually and offered to do this for us if we forget. I think they will have saved our bills in the long run.

Very nice young guy that came to my house.Very informative on everything.

We had a full kitchen and utility rip out and refit,we contacted Synergi to assist with the task from start to finish the hole process was made extremely easy and very professional, Synergi provided us with plumbers/electricians/plasterers and kitchen fitters, the hole team were very knowledgeable and helpful we didn't have to do anything. When we are next needing the same service it will be through Synergi again!

Another exceptional service from Synergi SW Ltd. Jason was outstanding and cant praise or recommened highly enough.

Great service from start to finish
Friendly, great value and very efficient
Would recommend to friends and family

The boiler stopped working over the weekend, so I rang Synergi first thing on Monday morning. They not only sent an engineer the very same day, but, to my amazement, the engineer of my choice, Adam Maud, who had carried out work at our house before, and was, therefore, familiar with our boiler, etc.
Adam is diligent and explains things very well to the lay person. He is also very friendly and has a good sense of humour.
The only thing that threw me a bit was that Synergi wanted payment for the first hour up-front. This was different from previous occasions, where we received an invoice for payment AFTER the engineer had been, which I think is normal practice.

The engineer Adam was polite, friendly & respectful of my property. He gave the boiler a thorough service at a reasonable price. The certificate of service was sent promptly afterwards by e mail. I would recommend this company.

The last that visited was polite and helpful. My discontent is towards the company charging people all of this money. The job took literary 5 min, only tighten the shower bolts, absolutely nothing else. They charged us £126. This is not good. I am not going to use this company any more, not for the boiler, too

Great communication and a super engineer. Adam was prompt, polite, friendly and efficient. I highly recommend this company.

Pleasant, confident, and efficient service engineer who explained what he had done, and what needed to be considered for the future.

Boiler required a service. Engineer came, said it needed a part. Paid for the service, paid for the part. Engineer came a few days later and fitted part. Few days later boiler wasn't working.
Engineer came again, said it needed another part. Paid for the part. Engineer fitted part. Few days later boiler wasn't working.
Engineer came again, said it needed another part. Paid for the part. Engineer fitted part. Few days later boiler wasn't working.
Engineer came again, said it needed another part. Paid for the part. Engineer fitted part. Few days later boiler wasn't working.
After £884, boiler still isn't working. Complained to Synergi SW. Unhelpful response. Boiler not working since March. Would never use this company again.

So, to clarify in light of your response:
The problem was raised in September and a service was scheduled for the 12th, for which I took a day's holiday from work.
At this point the boiler was working, but the pressure would drop on occasion, and the system would go off.
The service was cancelled abruptly due to illness of your engineer and I lost a day's holiday kicking my heels. The appointment was rescheduled for six weeks later at the end of October.
On the 28th, two days prior to the work being carried out, I received an invoice and a request for payment...
The service was completed on the 30th of October, cost, £170.40
I was informed that the engineer had identified an issue with the boiler, and that parts and labour totalling £400.44 would be required to complete the job.
I agreed to this on the 31st Oct and the work was scheduled for 11 November. Work was invoiced and paid for. Cumulative cost, £570.84
Shortly afterwards, I contacted you to inform you that there was now no heating, but that the hot water was unaffected.
Work was carried out on 29th January and I was invoiced £117.60 for a "Gas Boiler Service", with another invoice for the same job for labour, £108.76. So far, £797.20
The day after, you sent me a request to rate you on Trustpilot, which I declined, informing you instead that the problem had not been remedied. Indeed, it had got worse. Now the boiler would not operate at all, having to be reset frequently as it continually locked out.
On 11th February, the engineer discovered another issue, gave the boiler a clean, and recommended several other actions, including a power flush and replacement/clean of several other parts - £87.
Total so far, £884.20
Three weeks later, the boiler failed such that it was (and is) no longer able to provide either heating or hot water.
I sent you an email shortly afterwards entitled "Complaint", the first line of which read "I am writing to complain about the ongoing failure to repair my oil boiler, despite multiple service visits and significant cost incurred." I also mentioned in the email that I believed the service had failed the threshold for "Reasonable care and skill", directly quoting the Consumer Rights Act 2015, which deals specifically with instances such as these.
You chose to ignore this, instead basically refuting my premise that a failed diagnosis had been made on more than one occasion, and that I had paid for goods and services that had failed to solve the issue.
At no time was I informed of any specific complaints procedure I should follow, simply that I should allow you to carry out more work on my boiler.
I have absolutely no doubt your engineers are competent, and that this may have been a difficult problem to diagnose - although your engineers final recommendation was the same one that chat GPT threw up in September regarding what might be wrong with the boiler. Nor am I in any doubt that the issue was caused by a failure to have the boiler regularly serviced - we have not been in the house that long, but that does not excuse any part of this long and expensive saga.
The bottom line is that, after multiple visits and £884, I have no functioning boiler. Thankfully we have an electric shower.

Friendly staff from office to engineer. Diagnosed the fault with my boiler accurately and fast. Fixed and working again and the price was very reasonable. Can't recommend enough. Well done and thanks.

Have used Synergi SW for many years. Swift, efficient service.
Particularly like our engineer, Adam, he's always so prompt, cheerful and helpful 😊
Richard and the team deserve 5 stars and beyond.

Had the annual boiler service , boiler was fitted last year by SynergiSW Ltd . so no problems , engineer was friendly and precise , explaining different processes. All ok , and passed for another year.

Excellent service. Highly skilled engineer who thoroughly understood our LG heat pump and the underfloor heating system. We now have a properly commissioned and configured system. No hesitation in recommending Synergi.

The engineer (Ollie) turned up on time and did the service quickly, cleanly and efficiently. A very personable individual and a pleasure to work with.

Excellent service from initial telephone contact through to receiving boiler certificate. Polite, efficient and professional. Adam and Joe were prompt, polite and inspired confidence. They were happy to answer any queries and offer advice. Their service went beyond my expectations.
Synergy again impressed me at a reasonable cost.

I had a very old fire and heater removed Adam was a very polite guy who did the job quickly and capped the gas on both appliances he cleaned up and removed the fire heater to the door thank you for the professional repair man
