Domestic plumbing, repairs & installations

We cover the everyday jobs and the bigger ones: leaking pipes and joints, dripping or seized taps, running and blocked toilets, faulty stopcocks and isolation valves, low mains pressure, burst pipes and hot-water cylinder replacements.

When you're extending or refurbishing, the same team that builds the room plumbs it — bathroom and kitchen first-fix and second-fix, pipework re-routes, new supplies and wastes, all set out to water regulations and left clean, boxed-in and tested.

02 / 03

Commercial & maintenance plumbing

We hold planned and reactive maintenance arrangements with property managers, hotels, offices and retail clients across London. That means one number to call, engineers who already know the building, and work scheduled around your operating hours.

Typical works include washroom and kitchen installations, water heaters and calorifiers, booster and pressurisation sets, tap and cistern replacements at scale, leak detection and tracing, and pipework alterations for fit-outs — carried out with dust protection and minimal disruption, out of hours where needed.

03 / 03

Water regulations, backflow protection & RPZ testing

Every installation we complete meets the Water Supply (Water Fittings) Regulations. Where a property needs category-rated backflow protection, we specify, install and commission the correct device — including RPZ (reduced pressure zone) valves.

We also carry out the annual RPZ valve testing that keeps those installations compliant, with test certificates issued on completion and reminders when the next test is due.

What's included

A complete service, carefully coordinated.

Every plumbing job is scoped, priced and carried out by our own team — no subcontracted unknowns turning up on the day.

How It Works

How a plumbing job runs

A clear path from the first call to a tested, working system — with one point of contact the whole way through.

  1. Step 01

    Call or enquiry

    Tell us what's happening. For urgent leaks we'll talk you through isolating the supply straight away, then arrange attendance.

  2. Step 02

    Site visit & quote

    We attend, diagnose the real cause rather than the symptom, and send a fixed written quote. No call-out charge for work we've quoted.

  3. Step 03

    Scheduled works

    A named engineer carries out the work to water regulations, protecting floors and finishes as they go and keeping you updated.

  4. Step 04

    Test & hand over

    We pressure-test, check for leaks, clean down, and hand over with your workmanship guarantee and any test certificates.
