Top Plumb in Portsmouth were recommended to Deverell Hall in Purbrook to carry out some plumbing works at our local community hall. Dan Shaw was exceptionally helpful and turned up at the agreed time and date. The works were carried out to a high standard, they were in my opinion correctly priced, and we have approved his business for future works.
Dan was professional and helpful from the initial contact to completing the repair and resealing of my shower trap. He also helped with some advice on kitchen tap issue solution, which saved me some money. He’s polite, friendly and super knowledgeable about his trade. Wouldn’t hesitate to recommend Dan to anyone, he’s brilliant! He’s previously also replaced bathroom taps for my Mum, and did an excellent job there too.

Approved plumbers on the free WaterSafe register are vetted, qualified to the water regulations and insured. Check they're listed, or find a WaterSafe-approved plumber near you.
Check the WaterSafe registerAgree the call-out fee, the hourly or fixed rate, and whether parts are charged on top, in writing, before an emergency plumber starts. Out-of-hours overcharging and 'while I'm here' add-ons are common complaints.
Be wary of a plumber who, on a first visit, says your whole system or boiler must be replaced. Get a second opinion and an itemised quote (parts and labour separately) before agreeing to major work.
Gas and boiler work is a separate, regulated trade, not general plumbing. Make sure anyone working on a gas appliance is specifically registered to do gas work, and ask to see that registration before they start.
