BS 7671Cleaning depots, vehicle workshops and fleet bases run heavy plug-in machinery in environments where water, dust and impact are part of daily life. The fittings, the cable routing and the protection strategy are different from a typical office. We design for the real conditions on the floor.
Industrial vacs, scrubber-driers, pressure washers. Bench charging stations, dedicated cleaner-tool circuits, IP65 sockets in the kit-storage area.
Hot-water pressure washer arrays, foam injectors, vacuum stalls. Wash-bay water + electrics integration done to BS 7671 wet-zone principles.
Welding plants, MIG/TIG sets, ramp lifts, compressor circuits. Dedicated radial circuits per ramp, isolator at point of use, EICR-clean install.
Overnight fleet EV charging combined with outdoor 16A commandos for engine warmers, tyre inflators, mobile diagnostics rigs.
Single-trader and small-fleet bases for window cleaners, valeters, carpet specialists. Van EV charging plus tool-charge bench plus IP65 outdoor.
Self-service jet-wash bay supplies, sub-metered, RFID or coin-mech compatible. Dedicated isolator per bay so one fault doesn't down the site.
Commercial washer-extractors, gas-fired tumblers, ironing stations. 3-phase with proper phase balancing across the high-draw machinery.
Where workshop tools and fleet EV share one supply, dynamic load management balances the lot — charging throttles down when the welder fires up.
Every project starts with an existing-supply check, a load schedule for the new equipment, and a written design. The headline scopes below are the most common — actual work is sized to your machinery and the building.
Dedicated radial circuit, 30mA Type A RCBO, IP44 or IP65 enclosure as the location demands. Most cleaning machinery sits here.
Three-phase 400V supply, 4-pole RCBO, isolator at point of use. Ride-on scrubbers, big pressure washers, industrial laundry plant.
Spray-zone-aware design. Sockets and isolators outside the direct lance path, dedicated 30mA RCBO, full earth-loop and trip-time test pack.
Sized to the actual welder duty cycle on the spec plate. Local isolator, voltage-drop calc, harmonics aware on multi-welder shops.
Workshop compressors and 4-post lifts, sized to the inrush. Dedicated supplies so a compressor kicking in doesn't dip the lighting circuit.
Multi-charger fleet EV bay, load-balanced with the workshop power. OZEV grant up to £350/socket. See commercial EV page.
Three-phase commercial isolator — depot install, BS 7671 18th edition.
Final price depends on supply phase, distance from the board, civils (trenching / containment), the count of outlets and any DNO upgrade. Survey is free; written quote is fixed.
From first phone call to signed-off install — the process we run for every depot, workshop and wash-bay project.
60–90 minutes on site. Main fuse rating, live-load test, phase balance, IP-zone mapping, machinery load schedule. Existing board photographed.
Load schedule against available headroom. If supply upgrade needed, DNO request filed at this stage so timeline is honest. Cable routes mapped.
One price per scope, broken down per circuit. Materials, civils, isolators, certification all included. VAT @ 20% on a separate line.
First-fix containment and cabling, sub-board (where required) installed, outlets and isolators commissioned. Earth-loop and RCBO trip-time tested live.
EIC per circuit, NAPIT compliance cert from the national database, OZEV (if EV) confirmation. PDF pack emailed; warranty registered.
Most depot and workshop projects pair with a commercial fuse board upgrade — a dedicated sub-board for the new heavy plant, sized for future expansion. Where fleet EV is part of the scope, see the commercial EV fleet charging page. General commercial electrical work and ongoing contract maintenance wrap around larger sites. EICR testing for an existing depot fleet of fixed equipment is on the EICR page.
A 16A blue commando is single-phase 230V — typically used for industrial vacs, pressure washers up to 3kW, mobile floor scrubbers and most plug-in cleaning machinery. A 32A blue (single-phase) or red (three-phase) commando handles bigger draws — heavy-duty wet-dry vacs, industrial steam cleaners, three-phase rotary scrubbers and wash-bay pressure-washer pumps. The cable size, RCBO rating and isolator rating all step up with the load. We size the outlet to the spec sheet of the machine being plugged in, with headroom for future upgrades.
No. A wash bay is a wet zone with directed water spray under pressure — IP44 (splash-protected) is not enough. We install IP65 or IP67 enclosures and outlets, with the isolator and protective device housed in a separate IP-rated enclosure away from the spray path. Cable glands are torqued to spec, drain holes fitted, and the supply gets dedicated 30mA RCBO protection per circuit. Covers are sprung-loaded and self-closing so a missed lid doesn't compromise the IP rating.
Most industrial wet-dry vacs and pressure washers up to ~3kW run happily on single-phase 230V. Larger ride-on scrubber-driers, hot-water pressure washer arrays, big rotary buffers and chemical-injection systems often require three-phase 400V — the spec sheet will specify. We do an existing-supply check first: if the building already has 3-phase incoming, adding a 32A red commando is straightforward; if it's single-phase only, we discuss whether a DNO supply upgrade is worth it for the machine you're planning to run.
Yes — fleet EV is one of the strongest fits for a workshop or depot install because vans typically dwell overnight. We pair workshop power upgrades with 4–16 socket fleet EV bays, load-balanced so the cleaning machinery and the charge points share the supply without overload. The OZEV Workplace Charging Scheme covers up to £350/socket. See the dedicated commercial EV fleet charging page for full detail; on a depot project we usually scope both at the same survey.
The whole design is built around it. Wash-bay sockets are positioned outside the direct spray zone, mounted at minimum 1.2m where reasonable, and never in line-of-sight of a high-pressure lance. The earth electrode and bonding strategy gets the same scrutiny as a swimming-pool install — Section 702 BS 7671 thinking applied to a depot context. RCBO at 30mA is mandatory; we test and certify each circuit with full earth loop impedance, RCD trip time, and insulation resistance, signed off on the EIC.
First visit is a supply audit — main fuse rating, available headroom under live load, phase balance, condition of the incoming and the supplier-side cut-out. We log the readings, photograph the meter and intake, and produce a load schedule for the planned new circuits. If the existing supply has the headroom, we proceed; if it doesn't, we file a DNO (Western Power / National Grid) supply-upgrade request as a separate workstream — typically 6–12 weeks for a single-to-three-phase or capacity uplift on a commercial site. We don't bury it in the quote.
Whether it's a single 16A commando or a 4-bay wash facility with fleet EV alongside, the survey is free and the quote is fixed. NAPIT 66245, BS 7671 18th edition, VAT @ 20% on a separate line.
