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.

Central Heating Repairs
Frequently Asked Questions

What central-heating faults do you repair?

We assess no heating or hot water, cold or uneven radiators, recurring pressure loss, leaks from heating pipework or valves, unresponsive thermostats and controls, boiler lockouts and circulation problems. The repair scope depends on the diagnosed component and safe access.

Emergency heating help is available 24/7. We aim to attend within the hour, subject to location, traffic and engineer availability. This is an attendance aim; diagnosis, parts and safe working conditions determine whether the fault can be completed during the first visit.

Some thermostat, valve, pressure and accessible radiator faults can be completed during one visit. Boiler components, concealed pipework or manufacturer-specific parts may require more time. After diagnosis, we explain the expected repair duration and any return visit.

Yes, our heating repair workmanship is backed by our guarantee. The applicable scope and terms depend on the agreed job and are explained before work proceeds. This is separate from any manufacturer warranty that may apply to replacement parts.

Using the manufacturer’s user instructions, check the thermostat setting, boiler display or fault code and system pressure. Do not remove the boiler casing, dismantle valves or attempt gas work. If the checks do not restore operation, arrange an assessment.

Follow the boiler and control manufacturer’s maintenance guidance, act on pressure changes or leaks early and do not ignore repeated lockouts or unusual noise. Periodic servicing and prompt repairs can reduce avoidable faults but cannot prevent every component failure.

Replacement-part cover depends on the manufacturer, supplier and specific part. We explain any available part warranty for the agreed repair; we do not promise one universal period. Our workmanship guarantee is explained separately.

Yes. If a component is obsolete, repeated repairs are poor value or the system no longer meets the property’s needs, we can explain practical repair-versus-upgrade options. Installation scope and product terms are quoted separately before any change is made.

Check the controls and display only as allowed by the user manual, then call our 24/7 emergency heating team. If you smell gas, do not use electrical switches or flames; leave the property and call the National Gas Emergency Service on 0800 111 999 from a safe location.

Cost depends on diagnosis time, access, parts and the agreed work. We provide an estimate before starting. If the assessment identifies additional work, we discuss it before adding it, so there are no hidden additions to the approved repair scope.
