Detailed reviews
These are the individual reviews we hold for Drain Flow Services Ltd, including the highlights above. The 49 headline total is the review volume reported across public review sources.
Highly recommend Alex. Not only was our immediate drainage issue quickly resolved, but the underlying cause was found. We now have a new drain. Despite digging up a large area of path and garden to install the drain, the garden and path were completely restored, and the rubble promptly removed. An excellent job.
Alex did an excellent job for us. He identified an issue in our drains that was missed or deliberately overlooked by engineers from Thames Water. He was thoroughly professional, polite and efficient. I would not hesitate to have him back again.
We had some issues with an external drain over filling with excess rainfall. Alex visited and did a CCTV survey immediately pointing out where the issue was occurring. He recommended a simple solution and revisited about a week later to install the valve. We would highly recommend Alex and will certainly use him again if needed.

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.
