“Flash Plumbing Company did several different jobs around our flat. One of them was fitting a massive vertical radiator and soldering pipes, as the previously installed radiator was wider. He did a fabulous job, which was very aesthetically pleasing. He is very polite, patient, and has very fair prices. I would highly recommend Flash Company.”

Highlights
“Had my boiler replaced recently and the whole process was smooth from start to finish. Ash was on time, polite, and explained everything really clearly. The installation was done to an excellent standard, no mess left behind, and the new boiler is working brilliantly. I’ve already noticed how much better the heating and hot water are. Really happy with the service and would definitely recommend to anyone needing a boiler replacement.”
“Brilliant overall. Perfectionist, highly skilled, tidy, professional, reliable and courteous. We'd gladly recommend him. In fact, we are planning to use Flash for a new bathroom installation.”

Official checkOn the public register
Why this helps you judge trust: this trader is linked to a registered company with named people who are legally accountable for it, on an official register anyone can check, a layer of accountability an unregistered trader doesn't offer. Around 8 years on the register also points to an established business rather than a brand-new one.

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.
