Highlights
"Tony from Primary Flow had been the person I go to for all heating and plumbing problems. He is very knowledgeable professional- tidy and reliable. I have been a customer for a few years and have always received good service."
"The quote was competitive and the work was carried out immediately. Even though the job required extra work, because my existing pipework was old and not compatible, Tony did the work for the price of the quote. The work carried out was excellent, neat and to a high standard. Tony was polite, helpful and kept me informed regularly about the work he was carrying out. I would thoroughly recommend Primary Flow."
"Very professional work in both the quotation process and installation. Great choice of boiler which does everything I need."

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.
