“We have used K Marsh plumbers on a number of occasions. We had an emergency in our kitchen when the mixer tap came off and water sprouting everywhere. We turned the stopcock off and phoned K. Marsh. Alfie came as quick as he was able. He was very professional, gave good advice and was friendly and supportive. Well Done Alfie. We are very happy and satisfied.”

Highlights
“George was very efficient and stayed to complete the job when I had to return to local suppliers to replace faulty taps.”
“We recently replaced our sink with a vanity unit, tap, and basin that we had independently purchased. Unfortunately, the tap proved to be incompatible with the sink; however, the team were very professional, and solution-oriented in resolving the issue efficiently. In addition, they replaced the mixer tap on the bath to a high standard. Their timekeeping was excellent, and they conducted themselves in a polite, tidy, and professional manner throughout the work. Upon reviewing their website, I noted that they also offer a range of additional services, including electrical work, painting, and a monthly boiler protection plan. We would not hesitate to use their services again in the future.”

I had a nightmare finding a reliable plumber in South West London to replace a boiler who didn’t charge stupid prices. K Marsh Plumbing & Heating were the answer to my prayers! Very fair price for an excellent job. Lovely company. Personable, helpful and polite. I would be very glad to recommend them.

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.
