WRAS compliant · BS 8558 · L8 Legionella aware
Service overview
Plain-English breakdown, so you know exactly what you're paying for, and why it matters before we set foot on site.
Commercial plumbing, design, install and ongoing maintenance. Mains pressure boosting, calorifiers and water heaters, hot/cold distribution, TMVs, backflow protection, accessible-WC fit-outs, kitchen and washroom plumbing and full strip-and-refit projects.
Facilities managers, fit-out contractors, building owners and tenants in offices, retail, restaurants, gyms, surgeries, care homes and light industrial sites needing reliable, compliant commercial plumbing.
Office refurbishments and Cat A/B fit-outs, retail unit handovers, restaurant kitchen installs, gym/changing-room builds, accessible-WC additions, water heater replacements, mains pressure issues, low-flow complaints from tenants.
Commercial plumbing has a different rulebook to domestic, WRAS-approved fittings, BS 8558 design, ACoP L8 Legionella awareness, TMV2/3 valves on every basin in care/health settings. Domestic plumbers don't write the certificates a commercial occupier needs, and a non-compliant install becomes the building owner's liability the moment a tenant complaint reaches the Local Authority.
The cost of doing nothing
Commercial plumbing failures don't just inconvenience users, they breach statutory duties and create insurance and HSE exposure that builds over time.
Our process
Same system every time. No improvising on your floor.
We walk the site with facilities or the fit-out lead, log incoming mains pressure, existing pipework condition, backflow categories and any Legionella risk points.
Schematic, fittings schedule with WRAS approvals, TMV grades selected by use case, fixed written quote with phasing for live sites.
Mains upgrades, booster sets, hot/cold distribution, calorifiers, water heaters, TMVs, washrooms and kitchen plumbing, all WRAS approved fittings, all neat and labelled.
Pressure tests, TMV failsafe tests, backflow device tests, system flushed and disinfected to BS 8558 where required, temperatures verified at outlets.
Schematics, asset register, TMV service schedule, flushing regime and L8 risk notes handed over, with optional ongoing maintenance contract.
What you get
WRAS fittings, BS 8558 design, ACoP L8 awareness and TMV2/3 grades selected by use case, audit-ready paperwork.
Plumbing, gas, drainage and water heater work under one Gas Safe commercial roof, no finger-pointing between subcontractors.
Phased work, out-of-hours and weekend availability, isolation strategies agreed in advance with facilities.
Commercial-grade valves, brass-bodied where required, pipework supported and labelled, designed to a 25+ year service life.
Booster sets sized properly, branch sizing corrected, low-flow complaints from upper-floor tenants resolved.
Optional annual TMV servicing, L8 temperature checks and pipework inspections under a planned contract.
In depth
The details a salesperson skips. Skim it, or read every word, both are useful.
Most multi-storey or multi-tenant commercial buildings outrun their incoming mains pressure long before the supply itself becomes the limit. A properly sized variable-speed booster set, with break tank, smooths flow under simultaneous demand, keeps top-floor outlets usable and protects appliances from cavitation. We size against actual peak demand, not nameplate capacity, and integrate with BMS for fault reporting.
Not every mixing valve is appropriate for every setting. TMV2 valves are commercial-grade for general use, TMV3 valves are healthcare-grade with tighter failsafe tolerances for care homes, hospitals and surgeries. We're TMV2/TMV3 trained, select the right valve per outlet based on use case, and provide an annual servicing schedule that satisfies CQC and HSE requirements.
The Water Supply (Water Fittings) Regulations 1999 categorise every appliance by contamination risk (Fluid Categories 1–5) and require a matching backflow protection device. We assess every outlet on a commercial install, fit the right device (single check, double check, RPZ where required) and schedule the annual RPZ testing that's mandated for Cat 4+ installations.
Dead-legs, stagnant outlets, low-use taps and incorrectly set water temperatures are the textbook conditions for Legionella growth. ACoP L8 puts the obligation on the building duty holder. We design pipework to minimise dead-legs, keep hot above 55°C and cold below 20°C at outlets where possible, and document the system so your L8 risk assessment has accurate information to work from.
On office Cat A handovers we install the shell plumbing, mains, risers, water heater provision, and capped points for tenant fit-out. On Cat B we work to the tenant's layout, washrooms, kitchens, point-of-use water heaters and any specialist plumbing. We work to the fit-out programme, attend site meetings and hand over certificated on completion.
