Highlights
"Trennerys Plumbing and Heating are a most professional small business. All works were carried out efficiently and they were very well organised throughout the job. They were extremely polite and well mannered at all times. They were punctual and discussed the following days work with me so I would know how to prepare for them. The work was completed more quickly than anticipated. The original quote was adhered to apart from some extra work which I asked to be done while they were there."
"Fantastic! Darren did a complete renovation job on my bathroom. Everything new, pipe work hidden, re-plastering, lights, very funky shower. He fixed other issues he found with the boiler and loft tank along the way. 100% reliable, and the job came in at the price quoted. I wouldn't hesitate to recommend him - he's renewed my faith in tradesmen."
"Darren always helpful with advice and carried out work to high standards....highly recommended"

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.
