Shower replacement
A1 Services replaced our shower, which had stopped providing us with hot water The shower was examined prior to being replaced to ensure that replacement rather than repair was what was required, which my husband and I were happy with. The plumber who replaced the shower was efficient, polite, and knowledgeable about his job. Nothing went wrong, and the new shower is working well We would happily choose A1 plumbers again if needed in the future.

Friendly and efficient service as usual
A1 replaced our gas back boiler with a condensing boiler five years ago. We chose them because they took great care working out a practical solution for how to run the pipework to a new location upstairs with minimum disruption. The job was done very professionally and we have also used them for our annual boiler service ever since. They are always friendly, punctual, competent and efficient, and I would say the service is a very reasonable price. I am happy to recommend them.

Trustworthy indeed - good people
Fairly expensive, but I knew of the firm by reputation. Did a major boiler and system upgrade/update at fairly short notice after my boiler had been condemned (at no notice) by BGas. They did exactly what they said they would - and we couldn't have had a more helpful (and pretty tidy on a difficult 8-day job) fitter and apprentice. Inevitably fairly expensive - but there was a lot that needed doing. I have just received my bill - and find that there is a small reduction for work that I didn't need to have done! I have no hesitation in recommending.

Very disappointing and jaw-droppingly expensive
We rang to say what we wanted done, including the simple removal of a water heater which took about 20 minutes and the replacement of washers on four taps. The perfectly polite plumber came at the appointed time, did remove the water heater, then spent approx another 20 minutes looking at the radiators in the house because two of them were not heating up properly and advised us on the possible course to take. Very surprisingly, he did not have washers for the taps in his van, so took pictures of the taps and said he’d have to come back. So he came again a few days later. He replaced the washers but one of the taps drips more than before and makes a grinding sound when turned off. The entire time spent cannot have been more than half an hour at the most. When we asked him how much he thought the job might cost, he said that he had no idea because the office dealt with that side of things. Should we have taken this as a warning sign that the cost might be unreasonably high? The total bill was for £198. Reasonable?

Excellent workmanship
We needed to replace a gas back boiler and upgrade our system, which required relocating the boiler to the other side of the house A1 gave us the most practical option of any quote . The workmanship was superb, the fitter well presented and very competent . A very neat tidy job was completed in four days as proposed and as quoted .There was no mess to clean up afterwards. I can find no fault with the company or the staff. I throughly recommend them

Expensive
Failed to turn up the first morning, then man arrived at 7.30am rather than 8.00 the second day. Took 5 minutes to pack the stop cock, told me that it would save me a lot of money rather than a replacement as he sprinted for the door. The price was for the first hour and did not include VAT. I was given a small reduction. The tap is no longer dripping.

Active incorporated business
A1 Services (Oxford) Ltd is linked to a Companies House entry. This shows the business registration, not evidence of workmanship or service quality.
Why this helps you judge trust: this trader is linked to a registered company with named people who are legally accountable for it, on an official register anyone can check, a layer of accountability an unregistered trader doesn't offer. Around 30 years on the register also points to an established business rather than a brand-new one.
