Highlights
"Excellent tradesman, replaced old gravity/tank boiler to new baxi combi with digital thermostat (baxi uSense). Also re-plumbed living room and fitted new designer/tower radiators (3 in total). Happy to explained everything being done whilst working. Top guy with reasonable price, already recommended to family and friends."
"Antonio phoned me within an hour of me sending some questions about the issues with my boiler. He then came to the property at my earliest convenience and took a thorough look, where it became clear the old boiler had given up the ghost after 15+ years. Antonio then spoke me through every aspect of what he was quoting for in installing a new boiler and I received an official emailed quote the next day. He did the work with one of his colleagues within a day as planned, leaving no mess and taking all the old boiler paraphernalia with him. Everything working great - could not recommend more! Fab"
"Really pleased with the work. Exactly as discussed previously. Antonio was very friendly and went out of his way to tidy up after himself even though I told him it was fine. I highly recommend Parallel Plumbing and would use again for any other work I need done."

Antonio from Parallel came to my house to install an extractor fan. He was on time and within a couple of hours the job was done. Antonio was an honest, hardworking, professional, reliable and genuine person. Will definitely recommend him to friends and family.

I was pleasantly surprised with the great work from Parallel Plumbing. Antonio came to give me a quote and was very honest with me from the start. There were no hidden extras to bump the price up like some traders do. He was punctual every day, which is a big plus for me and worked non stop while he was here. The work carried out is to a very high standard and I would recommend to anyone and everyone! He was reliable, friendly, helpful and nothing was too much trouble. He made me feel at ease and I was comfortable asking questions. He did not make me feel silly for asking....
I was very happy with my new boiler. Antonio explained all of the options I had so I could choose the boiler that was most suitable for me. The work was carried out to a very high standard. Antonio was polite, professional and knowledgeable. I would definitely recommend him to others and would not hesitate to use his company again.
Friendly and reliable. Punctual and no mess. Would definitely use again.

Great job always.
Finding a reliable tradesman who is efficient, professional and not a rip of merchant is like gold dust. Antonio from Parallel demonatrated good workmanship and a lovely guy that rectified my leaking shower problem quickly and very comparatively priced.

Before you hire a gas engineer
By law, anyone working on your gas appliances must be on the Gas Safe Register — ask to see their Gas Safe ID card and check the licence number at gassaferegister.co.uk before they start.
Never let an unregistered person touch your gas: unsafe gas work risks carbon monoxide poisoning, fire and explosion, and is a criminal offence.
For a boiler or appliance install, get the work and price in writing and keep the Gas Safe / Building Regulations certificate they are required to give you.
Confirm they cover your area and can actually come out in your timeframe before anything else.
Read recent reviews for reliability and turning up on time — not only the quality of the work.
