Highlights
"Could not recommend more. Very knowledgeable and friendly. Had a leak in my bathroom which was in a very tricky position (and also that I had wrongly diagnosed). The leak was correctly detected, and fixed without the possible major disruption the position of the leak may have required. Would recommend using Alpha to anyone and will definitely be my first choice for further work."
"Professional work, clean and tidy"
"Absolutely fantastic service, great communication, good price and professional clean tidy job. Will definitely be using for plumbing jobs in the future and would recommend their services. Definitely a trusted and reputable plumber, thank you"

Gas work is restricted by law to Gas Safe registered engineers. If they'll touch a boiler or any gas appliance, confirm they're currently on the register before you hire - it's free and takes a minute.

Smart checks
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.
