Electrical Certificates Explained: EICR vs PAT vs Landlord Certificate
Confused about electrical certificates? Our NICEIC-approved West Midlands electricians explain the difference between EICRs, PAT testing, landlord certificates and electrical installation certificates — plus when you need each one.
The Different Types of Electrical Certificates
If you are a homeowner, landlord or business owner in Birmingham, Wolverhampton or anywhere across the West Midlands, you have probably heard of various electrical certificates — EICR, PAT testing, Electrical Installation Certificate and more. But what is the difference between them, and which ones do you actually need?
Our NICEIC-approved electricians carry out all types of electrical certification across the West Midlands every day. Here is our straightforward guide to understanding each certificate.
EICR — Electrical Installation Condition Report
A comprehensive inspection and testing of all fixed electrical installations in a property — wiring, consumer units, sockets, light fittings and earthing.
Every 5 years for rental properties (legally required). Every 10 years for owner-occupied homes (recommended). Every 5 years for commercial properties.
All landlords (legally required). Homeowners selling or buying. Commercial property owners. Anyone wanting to check their electrical safety.
PAT Testing — Portable Appliance Testing
A series of visual inspections and electrical tests on portable appliances — kettles, computers, power tools, extension leads, fridges and any equipment with a plug.
Varies by equipment type and environment. Office equipment: annually. Power tools and construction equipment: every 3 months. Hotels and schools: annually.
Employers (legally required under the Electricity at Work Regulations 1989). Landlords (recommended for furnished rentals). Schools, hotels, shops and offices.
Landlord Electrical Safety Certificate
A certificate confirming that a rental property meets electrical safety standards. This is based on a valid EICR with no C1 or C2 issues, plus confirmation that all remedial work has been completed.
Every 5 years, aligned with the EICR renewal cycle. Must also be provided to new tenants before they move in and to existing tenants within 28 days of inspection.
All private landlords in England (legally required since 2020). Social landlords. HMO landlords. Councils can fine up to £30,000 for non-compliance.
Electrical Installation Certificate (EIC)
A certificate issued after new electrical work is completed — such as a full rewire, new circuits, or a consumer unit replacement. It confirms the work meets BS 7671 standards.
Issued once after new work is completed. Valid for the lifetime of the installation (but an EICR is still needed periodically).
Anyone having new electrical work done. Building control requires it for notifiable work (new circuits, consumer units, house rewires).
Minor Electrical Installation Works Certificate (MIEWC)
For smaller jobs like adding a new socket, replacing a light fitting or extending an existing circuit, a Minor Electrical Installation Works Certificate is issued instead of a full EIC. This confirms the specific work meets safety standards.
