How we price commercial work

We don't publish a price list for commercial work because no two jobs are the same. Building age, access, scope, in-hours or out-of-hours scheduling, existing wiring, materials and certification scope all change the price. We survey first, then give you a fixed written quote.

Common questions

What's the difference between a residential and commercial electrician?

Commercial work has different regulatory weight: BS 5839-1 fire alarm grading (Cat L1/L2/L3/L4/L5 or M), BS 5266 emergency lighting with annual full-discharge testing, periodic EICRs at the interval your inspector or insurer sets, three-phase 400V supplies, larger consumer units (Hager / Wylex / Schneider commercial ranges), plus PAT testing on portable equipment. We hold NAPIT 66245 specifically because commercial clients ask for it before they'll let you on site.

How often does commercial premises need an EICR?

No law sets a fixed EICR interval for businesses. NICEIC recommends at least every 5 years; the recommended maximum periods by type of premises in IET Guidance Note 3 are not legal requirements, and your insurer or landlord may ask for more often. We offer annual inspections for customer-facing premises.

Do you do fire alarm installs and emergency lighting?

Yes, full BS 5839-1 fire alarm design and install (Cat L1, L2, L3, L4, L5, M) and BS 5266 emergency lighting design, install and annual 3-hour discharge testing. We issue the design certificate, installation certificate and commissioning certificate as a complete package, and add the premises to our service rota for the annual tests.

Can you handle three-phase 400V installs?

Yes, three-phase commercial supplies, sub-mains, motor circuits, large kitchen ranges (60A+), wash-bay 32A/63A red commando, factory/warehouse distribution, fleet EV bays load-balanced across phases. If the existing supply is single-phase only, we file the DNO supply-upgrade request as a separate workstream, typically 6-12 weeks for a single-to-three-phase capacity uplift on a commercial site.

Do you cover out-of-hours and weekend work?

Yes, most commercial board changes, fire-alarm panel replacements and big circuit additions need power off, which means trading hours don't work. We routinely do Saturday-morning shutdown windows or evening starts, with everything tested, certified and live again before the doors open Monday. Quoted as a fixed price for the works, with an out-of-hours premium for Sundays and bank holidays.
