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. - For the water-regulations side of plumbing, a WaterSafe-approved plumber is vetted, qualified to the water regulations and insured. You can check yours or find one free at watersafe.org.uk. - Look for consistent reviews across several named sources, not one polished profile. ## Contact - Phone: 07511 096012 --- Source: MyTrustedTraders, https://mytrustedtraders.com/traders/trader-695229-rp Real public evidence only: every figure traces to its named source.
