Avoid, avoid, avoid, stay way clear of this company. They send an incompetent engineer, who did not have the right tools, broke my flooring and then left saying they could not complete due to the pipe size, yet they are meant to be the expects. I was not pleased about the damage, but not once did I behave aggressively to the older looking engineer.
I rang to complain, spoke to a lady who said she has to wait for the engineer’s report. 10 mins later, I receive the report that labelled me as aggressive and agitated, as a result he left because of that. Total lies, he could not do the job. The company finished by saying they would not return to my address, as if I would want them back again. Don’t trust them and certainly no customer services, I was not charged for the visit and I wouldn’t have paid anyway as they did nothing and damaged my floor board.

Would not recommend this company - avoid if you value your time and money !!
First, I had to call three times in order to secure an appointment (each time I was told I'll get a callback, which never happened).
Then, the day before I'm told my appointment has been cancelled and rescheduled for the next day - a real inconvenience for me, as really last minute notice to rearrange my work etc.
Then, on the rescheduled day, the engineer was supposed to arrive at 12pm and I was meant to get a call/text when he was on his way. By this point it was now 2pm and had heard nothing. I phoned the office, only to find the engineer was at a car mechanics! If I hadn't called, I would not have been told. So, he rocked up 3 hours late in the end.
When he arrived, he seemed confused by the job - he had been told it was just a hob connection, not to take out the old one and replace it with the new. I had clearly explained 3 times on the phone what the job was, so again, another breakdown in communication.
Then, the engineer took 2.5 hrs to complete the job!! Constantly going back and forth to his van, installing it and then realising some wood was in the way at the back of the over space, so then had to undo his work, and then re-do it again. It was very unprofessional and I didn't feel confident with it at all.
Finally, after I communicated all of this, I was told I'd receive a 10% discount for the troubles, which surprise, surprise, was not added to the final bill!
After getting in touch with them again, the 10% discount was finally added. But for a job that took 2.5hrs, which should have taken only an hour with the right person, and at a steep price of £95 + VAT, it was a big dent in my pocket.
So please AVOID this company, it has been so unprofessional and expensive!

We are very impressed by the recent installation of air conditioning units in our domestic residence. All the engineers were considerate, careful, and demonstrated their technical expertise throughout the installation process. There was a minor install issue, which was resolved immediately. The technical installation was followed by a decorator whose work was meticulous. We also very much appreciated the kindness of the booking staff, who made a real effort to support us during this heatwave, through stock and shipping issues.

Engineer (Chris) booked for a gas hob installation. There were some problems he could not have foreseen which he dealt with efficiently and professionally. Clearly knew his stuff. Cost was reasonable and as quoted, so I would use JAR again. Happy customer.

My initial enquiry was made to “Poplar Plumbing,” which appears to have been redirected to JAR Mechanical. That is misleading -- the company is presenting itself as a local provider when it is not.
I instructed JAR to attend on Friday 30 January 2026 to: (a) replace an extractor fan; (b) check that radiators were functioning; and (c) resolve drainage issues affecting a bathtub and sink.
Their engineer wasn't able to complete the job because he had attended without the necessary equipment (a long snake drain, which I would expect to be in a plumber's toolkit in any event). They then invoiced me £342.00.
I was told that a return visit could take place the following day if I paid the invoice and a further £485.00. They refused to explain this figure, even though the only outstanding issue was a blocked drain. After I challenged this, the price was reduced to £90 + VAT.
After I left a negative review on Trustpilot, they threatened me that they would not return to complete the work unless I removed it. That was completely inappropriate.
I was desperate to get the bath draining, so I paid the invoice and deleted the review. Their engineer failed to show up as arranged on Saturday morning, and I was unable to contact anyone at the company by telephone or email so had to wait around at home until I gave up.
When an engineer eventually attended, he remained for less than an hour and showed me photographs of some hair removed from the drain. I confirmed by email that it looked as if the bath was draining normally. However, within a week, the bathtub was again not draining, indicating that the issue was not properly resolved.
As a result, I now need to instruct another plumber to complete the work. Meanwhile, JAR Mechanical are harassing me for payment of their £90 + VAT bill even though they didn't finish the job properly.
AVOID AT ALL COSTS
We needed leaky pipework replaced as part of making a house safe for an elderly relative to allow her to return home from hospital. JAR came up with a quick an efficient solution and were very appreciative of our predicament. They provided a very friendly and professional service.

Antwort von Jar Mechanical LTD
I called this company because I had identified a leak from a radiator valve and my boiler was losing pressure. The company has since responded to my review claiming that their recording shows I called requesting a boiler service. That is not an accurate description of why I called.
I called because I had a leak and was looking for help resolving it. I did not independently request a routine boiler service. If a service was discussed, it was in the context of investigating the leak and loss of pressure.
Rafal attended the property with the leak still present. No repair was carried out. Instead, a boiler service was performed while the system had a known leak, and I was charged £114. I was then given an estimate of £5,000–£6,000 to resolve the issue.
The same day, I contacted another company. They repaired the leak for under £150.
So I went from being told I was potentially looking at £5,000–£6,000 to having the actual problem fixed for less than £150 on the same day.
Rafal himself later suggested that I find another engineer, acknowledging that someone else would likely provide a different quote. That turned out to be very good advice.
My biggest issue is that I contacted this company because I had a leak and a boiler losing pressure. I paid £114, the leak was left unrepaired, and I walked away with a £5,000–£6,000 estimate. Another engineer then resolved the problem for under £150.
Based on my experience, I would not recommend this company.

Antwort von Jar Mechanical LTD
AVOID this engineer. I regret ever finding him online. Find someone honest, capable, ethical.
Very quick and easy, Rafal was very useful and helpful. All in all great and smooth experience.

Professional service. Rescheduled my appointment at first but when arrived we got good service.

Jason visited my house today after a gas leak was detected and was excellent with deducing the exact problem and implementing the solution for it quickly. His explanations were clear and I am confident in using JAR in the future again and absolutely recommend them to others.

Excellent care from beginning to end. Appointments kept on time and work carried out by friendly and efficient Rafal. Everything left clean and tidy. Cannot fault . Would recommend.

Antwort von Jar Mechanical LTD
Excellent service from JAR & Rafal.
He diagnosed the issue with our central heating system quickly despite our previous plumbers being unable to identify the problem.
It was then fixed quickly & cleanly & restored to full working order.
Rafal was efficient & courteous throughout & clearly knew his stuff.
No hesitation in recommending JAR.
