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.Posted on Google![]()

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 reccommendPosted on Google![]()

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.Posted on Google![]()

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.

Frequently Asked Questions
What is included in a domestic drain installation assessment?
We review the intended use, route, access and existing connections before defining the proposed domestic work. The quotation then states the installation scope, materials, access assumptions and testing for the installed section.
When might a new drain installation be appropriate?
Planned installation may be appropriate for an alteration, a new domestic waste connection or replacement of an agreed damaged section. The right solution depends on the property and must be assessed before work is specified.
What type of drainage work does this page cover?
This page covers planned domestic waste and drain installation work that can be defined after a property-specific assessment. It does not claim commercial, civil, stormwater, soakaway or broad infrastructure capability.
How long does a drain installation take?
Duration depends on the route, access, ground or building conditions, materials and testing required. We provide a likely programme after the installation scope has been assessed and agreed.
How are installation materials selected?
Materials are selected for the agreed use, route, connection and site conditions. We state the proposed specification in the estimate rather than promising a particular material before assessment.
Can every installation be completed without excavation?
No. Excavation or opening-up requirements depend on the route, access and connections. We do not promise a trenchless or no-dig installation before the site has been assessed.
How do you limit waste and disruption?
We plan access and sequencing around the agreed route and explain likely disruption before work. Any claim about sustainability or a special environmental system would require a separate, verified specification.
Do you claim commercial or civil drainage installation?
No. This page is intentionally limited to assessed domestic drain installation work. Commercial, civil and specialist drainage systems are not advertised here without separately verified capability.
How much does a drain installation in London cost?
Cost depends on the route, access, materials, connections and testing required. We provide a transparent estimate before work begins, with no hidden additions to the agreed scope.
How should a newly installed drain be maintained?
Use drains only for their intended waste, avoid fats and unsuitable items, and follow any project-specific aftercare. If flow changes or a blockage recurs, arrange an assessment instead of mixing chemical cleaners.
