Commercial Electrical
Commercial electrical work covers everything from office and retail fit-outs to 3-phase supplies, machine feeds, and plant room electrics for commercial and industrial clients, alongside the periodic testing and certification commercial premises need.
When You Need Commercial
- You're fitting out a new commercial unit, office, or retail space
- Your business needs a 3-phase supply, machine feed, or plant room electrics installed
- A commercial EICR or periodic inspection is due for your premises
- You're expanding capacity and your existing supply or distribution board can't cope
Commercial Cost
£350–£817
Commercial projects vary too widely for a single price range to be meaningful — this figure covers only small-scope work; every commercial job gets a project-specific, fixed quote after a site visit.
What affects the price?
- • Scale and complexity of the fit-out or installation
- • Whether a 3-phase supply or upgrade is needed
- • Site access and working hours (some commercial sites require out-of-hours work)
- • Compliance/testing requirements specific to the premises type
How Long Does It Take?
Small commercial jobs can be same-day; fit-outs and larger installations are scheduled and phased around the wider project timeline.
Regulations & Standards
Commercial and industrial installations are designed, installed, and tested to BS 7671, with periodic inspection and testing carried out to the interval appropriate for the premises type and use.
Frequently Asked Questions
Do commercial premises need an EICR?
Yes — commercial and industrial premises need periodic electrical inspection and testing, typically more frequently than domestic properties, with the interval depending on the type of premises and how the installation is used.
Can you install a 3-phase supply?
Yes — we design, install, and test 3-phase installations for commercial and industrial sites, including machine feeds and plant room electrics, and can liaise with your DNO where a new or upgraded supply is needed.
How much does commercial electrical work cost?
It depends entirely on the scope — a small office fit-out and a full 3-phase industrial installation are very different jobs, so we always provide a project-specific fixed quote after a site visit rather than a generic price.
