Common heating emergencies we assess

No heating

A boiler lockout, circulation fault, controls issue or system-pressure problem may stop the property heating.

No hot water

Loss of hot water can involve the boiler, cylinder, controls or other system components and needs proper diagnosis.

Boiler fault or lockout

Record the display code and avoid repeatedly resetting the boiler if the fault returns.

Heating leak

Turn off the affected appliance or water supply only when safe and keep people away from escaping hot water.

Radiator or control failure

Cold radiators, faulty valves or controls and uneven heat can indicate a local or system-wide problem.

Used Alex as a local based plumber to fix an issue with the taps. He knew what the issue was likely to be and came prepped on the first visit, but sadly after opening the taps up it was a full replacement required, but Alex ordered the replacements and fitted the new taps a week later quickly and to a high standard.

Very efficient. Our boiler was v old and basically about to go bust. Previously used British Gas, who were useless - signed off the boiler without even looking at it, whereas Alex was fully and transparent, came originally and realised it was a much larger job, didn't charge came back and spent hours fully fixing and repairing. Saved us having to buying a new boiler. Would highly reccommend

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.
