“we had a great experience with this company. the engineer was prompt, friendly and thorough and kept me informed throughout, even navigating an anxious dog who had to be moved between rooms so he could get to every radiator! the invoice amount was adhered to and I had a call before the engineer arrived to let me know he was on the way. all in all great service and would recommend”

Highlights
“Absolutely superb! They called, arrived on time, did what they said and all with such professionalism and pleasantness. I can only highly recommend them!”
“The company did a good job waiting until all the radiators had been received from their suppliers, so that there would be no interruptions during installation activities. However, only about 5 hours of work was done each day, due to child care needs; this was not advised in advance. This meant that the installation activities went on for 4 days, leaving the house colder for 4 days. There were some problems noticed subsequently with a leak on one radiator, and the boiler cutting out at the boiler thermostat max setting; which had not happened previously. Now more works need to be done.”

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.
