I've used Plumbing 4 London multiple times over the years, and I honestly can't recommend them highly enough. They really proved their worth on a major project where another plumber had completely let me down. They stepped in, quickly identified the issues, and got everything back on track with professionalism and expertise. They're always on time, provide honest and accurate advice, and never try to upsell unnecessary work. It's refreshing to deal with someone who's genuinely reliable, trustworthy, and takes pride in doing the job properly. If you're looking for a plumber who turns up when they say they will, gives the right information, and delivers quality work every time, Plumbing 4 London is an outstanding choice. A genuine, dependable chap who I'll continue to use and happily recommend to anyone.

Our boiler suddenly stopped working on a freezing morning. I contacted UK Gas Engineer Ltd and they had an engineer out the same day. He quickly found the fault explained everything in simple terms and had the heating back on within the hour. Fantastic service.

Came home from on holiday on 03/01/26 to the boiler not working - not heating or hot water - on one the coldest days of the winter. Was calling round desperately to find emergency plumber at 8pm on a Saturday. Despite calling multiple plumbers, none could come until the Monday...Then there was Alex! He came round on that Saturday night, found the problem and made a plan to replace the broken part. He was AMAZING! He was upfront about costs, timings, issues and part sourcing. Within 72 hours (part sourcing and error code issues that, were unrelated to Alex, were an issue) We had our boiler back working. Very grateful to Alex, who was so in demand and worked like trooper, would 100% recommend him

Heating FAQs

How often should I have my heating system serviced?

  • System turning on and off frequently (cycling)

We service and install a variety of heating systems, including:

  • Boilers (gas, electric, and combi)
  • Radiators and underfloor heating systems
  • Heat pumps and solar heating solutions
  • Smart thermostats for better control and energy efficiency

If your heating system stops working unexpectedly, contact us immediately. We offer 24/7 emergency heating repair services to get your system back up and running as quickly as possible. Avoid attempting repairs yourself unless you are a qualified professional.
