What Electrical Compliance Does a London Commercial Property Need?
Every commercial property in London must meet a set of electrical and fire safety standards, regardless of whether it is owner-occupied or leased. The core requirements are: an up-to-date Electrical Installation Condition Report (EICR) every 3–5 years, a fire alarm system maintained to BS 5839-1:2025, emergency lighting tested to BS 5266-1, portable appliance testing (PAT) at appropriate intervals, and adequate RCD protection on socket circuits.
These requirements are not optional. They are enforced through multiple pieces of legislation, and non-compliance can result in significant financial penalties, criminal prosecution, and invalidated insurance.

Who Is the "Responsible Person"?
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person for a commercial property in London is the person who has control of the premises. For a landlord-occupied building, this is typically the business owner or employer. For a leased property, the landlord is responsible for common areas and the building structure, while the tenant is responsible for their demised area.
In practice, many landlords appoint a facilities manager or managing agent to fulfil these duties on their behalf. However, the legal responsibility cannot be fully delegated — the landlord remains personally liable for ensuring compliance.
What Are the Penalties for Non-Compliance?
EICR non-compliance: Up to £40,000 per breach. Local authorities can issue these penalties directly without court proceedings.
Fire safety breaches: Under the Fire Safety Act 2021, penalties for fire safety failures are unlimited fines and up to 2 years' imprisonment. The London Fire Brigade is particularly active in enforcement.
Insurance implications: An electrical incident in a non-compliant property will likely result in the insurer refusing to honour the claim. This can mean the landlord bears the full cost of damage, business interruption, and third-party claims.
How Often Do You Need Inspections?
