K Roberts1.0 / 5 ·

Terrible service. Quote for £850 accepted to do all the work. Actually did half and got my wife to believe it had all been done. She paid in full the same day. I made contact with James he stated he would get someone to complete the work asap but never did. Review put in Checkatrade. James not happy with poor review used intimidation on phone telling me to take it off. Very nasty actually. No sign of half money returned. Professional NO. Trustworthy NO. You got the picture.

Mr Hampton5.0 / 5 ·

Unfortunately we were one of many effefed by the freezing temperatures earlier this month (March 2018). Our condense pipe to our boiler had frozen, and we called out Alloy Plumbing, they came out immediately and sorted the problem. The engineer was Polite & kept us well informed throughout, the price of the emergency call out was cheaper than other companies we had called prior to Alloy. Highly recommend.

  • Emergency availability: 24-Hour

These are statements the business makes on its own website, worth confirming in writing (and on the official registers) before you hire, not independently verified by us.

Your own checks

What to check before you hire

Worth checking yourself
Always confirm credentials and quotes with the business directly before hiring.
Verify at the sourceCheck them yourself

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 register
Agree 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.
