FAQs (Commercial Electrical Contractors Services)
Do businesses legally need an electrical safety certificate?
Yes. Under the Electricity at Work Regulations 1989, all businesses must ensure their electrical systems are safe, maintained, and suitable for continued use. While the law does not use the term “certificate,” the recognised method of proving compliance is a Commercial EICR (Electrical Installation Condition Report). Most insurers, landlords, and local authorities require a valid EICR as evidence of electrical safety.
What is a commercial EICR and how is it different from a domestic one?
A commercial EICR is a detailed inspection and testing of a business’s electrical installation. It is more complex than a domestic EICR because commercial sites often have:
- Three‑phase supplies
- Larger distribution boards
- Higher loads
- Machinery or specialised equipment
- Emergency lighting circuits
- Fire alarm interfaces
- Industrial wiring systems
The testing is carried out to BS7671 and must be performed by a qualified commercial electrician.
How often does a commercial property need electrical testing?
Typical recommended intervals:
- Offices: Every 5 years
- Shops & retail: Every 5 years
- Restaurants & catering: Every 5 years
- Factories & industrial: Every 3 years
- Schools: Every 5 years
- Construction sites: Every 3 months
- Commercial landlords: As required by insurers or tenancy agreements
If the previous report recommends a shorter interval, you must follow that.
What electrical checks are required for shops, offices, warehouses, and restaurants?
Commercial properties typically require:
- Commercial EICR
- Emergency lighting testing (BS5266)
- Fire alarm testing (BS5839)
- PAT testing for portable appliances
- Distribution board inspections
- RCD testing
- Thermal imaging (optional but recommended for high‑load sites)
These checks ensure compliance with the Electricity at Work Regulations and fire safety legislation.
What causes commercial electrical installations to fail an inspection?
Common reasons include:
- Overloaded circuits
- Damaged or deteriorated wiring
- No RCD protection
- Poorly maintained distribution boards
- Incorrect cable sizing
- Loose terminations
- High earth loop impedance
- DIY or unqualified electrical work
- Lack of earthing or bonding
- Old or obsolete equipment
Industrial and high‑load environments fail more often due to heavier usage.
Do businesses need PAT testing and how often?
PAT testing is not legally mandatory, but businesses must ensure electrical equipment is safe under the Electricity at Work Regulations 1989. Typical intervals:
- Offices: Every 12–24 months
- Shops & retail: Every 12 months
- Restaurants & catering: Every 6–12 months
- Construction: Every 3 months
Insurers often require PAT testing as part of their policy conditions.
Who is qualified to carry out commercial electrical work?
Commercial electrical work must be carried out by a competent, qualified electrician with:
- BS7671 qualification
- Commercial/industrial experience
- 2391 (or equivalent) inspection & testing qualification
- Registration with NICEIC or NAPIT
Commercial installations require higher competence than domestic work.
What happens if a business fails a commercial EICR?
If the EICR is unsatisfactory:
- Defects will be coded (C1, C2, C3, FI)
- C1 and C2 issues must be rectified
- FI items require further investigation
- A qualified electrician must complete remedial work
- A “satisfactory” certificate or written confirmation is issued after repairs
Many insurers require proof of remedial work to maintain coverage.
