From a dripping tap to a full bathroom re-plumb, ARI handles domestic and commercial plumbing across London and the M25: fully insured plumbers, written quotes before any work, 12-month guarantee.
Plumbing is the trade that installs, maintains, and repairs the pipework, fittings, and fixtures that bring water in and take waste out, including taps, toilets, basins, baths, showers, radiators, washing machines, dishwashers, and the supply and waste pipes connecting them all. London plumbing is its own specialism: shared drainage in flats, lead pipes in Victorian terraces, communal risers in modern blocks, and the freeze-thaw burst-pipe season every January are problems most general plumbers from outside the capital struggle with.
ARI Maintenance has been working on London plumbing since March 2025. Every plumber on our team is fully qualified, fully insured, and used to the way water moves (and gets stuck) in this city’s buildings.
Six categories that cover almost every plumbing call we get.
Burst pipes, major leaks, no-water situations, no-hot-water situations, and overflowing toilets. We respond within 1-2 hours during working hours and operate a 24-hour emergency line for out-of-hours calls. Most emergencies are stabilised on the first visit.
See our emergency plumber pageA burst pipe can dump 600 litres of water into a property in an hour. We carry copper, plastic, push-fit, and compression fittings in every van so the repair happens on the first visit, not a promise to come back tomorrow with the part. Typical repair time is 1-3 hours, depending on access.
Slow drains, gurgling pipes, and standing water are signs of a blockage. We use manual rodding, hand augers, and high-pressure jetting to clear sinks, baths, toilets, and external drains. We diagnose recurring blockages caused by tree roots, scale build-up, and collapsed pipes.
Blocked drains page Blocked toilet pageNew shower installations, mixer and electric shower fitting, shower pump upgrades, re-sealing around trays and enclosures, and diagnosing pressure or temperature faults. Booked alongside bathroom refurbishment work or as a standalone job.
Full plumbing for bathroom and kitchen refurbishments led by Sam, covering first-fix and second-fix work, isolation valves, soil stack connections, and fixture installation. Domestic and small commercial.
Tap washer and cartridge replacements, toilet replacements (close-coupled, wall-hung, back-to-wall), radiator installation, bleeding, and thermostatic valve fitting.
Four outcomes that separate us from the average plumber search result.
If the emergency is happening now, this is the call that ends the panic. 1-2 hour response, parts in the van, problem stabilised before we leave even if the full fix lands the next day.
Free site survey or written quote within 48 hours. Every job is confirmed in writing before any work starts, with no surprise extras on the invoice.
Repeat work goes to the same named plumber so you don’t re-explain the job every time. The plumber knows your stop tap and the radiator on the third floor that always needs bleeding.
12-month workmanship guarantee on every plumbing job. Public liability insured. If the same fault returns inside the warranty window we come back at our cost.
The same five-step process every plumbing job follows, from a dripping tap to a full bathroom re-plumb.
Phone 020 8068 2295, email, or send photos. Tell us what is happening and where. We diagnose by phone where we can, which saves a visit if it is a known fix.
Most non-emergency jobs need eyes on the pipework. We come out, identify the fault, and check access for parts and disposal. Free of charge for standard estimates.
Itemised quote: labour hours, parts, disposal, VAT. Materials priced separately so you can compare, and the full scope is agreed with you in writing before we start.
Common fittings live in our vans. Most plumbing repairs are completed in a single visit. Larger jobs (refurbishments, full re-plumbs) get a confirmed start date and schedule before we arrive.
We test, walk you through the work, and clean up. 12-month workmanship guarantee in writing. We still answer the phone afterwards.
According to the WaterSafe approved-contractor scheme, an estimated 1 in 6 plumbing jobs in the UK is carried out by someone without the qualifications to be working on the public water supply, leading to higher rates of poorly-fitted backflow protection, contaminated drinking water, and Building Regs failures. Working with a fully qualified plumbing team is not a luxury; for landlords with HMO obligations and homeowners selling on, it is a compliance question.
Every plumber on our team is fully qualified, fully insured, and rated highly by our customers on Google and Checkatrade. We carry public liability cover, provide written guarantees on every plumbing job, and agree the full scope with you in writing before any work begins.
ARI Maintenance is led by Arianne ‘Ari’ Raofi, founder, who built the company in March 2025 to give London property owners one accountable team for every trade. Ari is on every plumbing quote that goes out the door and personally signs off the larger jobs, including refurbishment plumbing, full re-plumbs, and commercial work. Day-to-day plumbing repair work is carried out by named, qualified members of our team backed by Ari and James’s hands-on diagnostics.
“Most plumbing problems are not really about the pipework. They are about whoever fitted it last time cutting a corner. Our job is to find the corner that got cut, fix it properly, and tell you what to watch for next.”
Every plumbing job gets a clear scope and a written quote before any work starts, so you know exactly what is being done before we pick up a tool.
Materials are itemised separately on every quote, and nothing is added to the job without agreeing it with you first.
