What Are the Electrical Regulations Every London Landlord Needs to Know in 2025?

If you're a landlord in London, staying compliant with electrical safety laws isn't optional—it's essential. As of 2025, there are updated legal responsibilities that you must understand to avoid fines, void insurance policies, or even endanger tenants.

At Lumiel, we work closely with landlords across South West London and beyond to ensure properties are safe, efficient, and legally up to date. In this post, we break down the key electrical regulations every landlord needs to know in 2025—in plain English.

1. Electrical Installation Condition Reports (EICRs) – Still Mandatory

Under the Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020, all rental properties in England must have a valid EICR (Electrical Installation Condition Report) carried out at least every 5 years.

What's required in 2025:

• A qualified electrician must inspect and test the property's fixed wiring and electrical system.
• You must provide a copy of the EICR to new tenants before they move in.
• You must give the EICR to existing tenants within 28 days of the inspection.
• If any “C1” (danger present) or “C2” (potentially dangerous) faults are found, they must be fixed within 28 days—and a written confirmation of the repairs must be submitted to the tenant and local authority.

💡 Lumiel Tip: We offer fast-turnaround EICRs with same-day certification delivery, perfect for landlords on tight timelines.

2. New Changes in 2025: Enhanced Certification for HMOs and Short-Term Lets

As of April 2025, London councils have rolled out additional electrical requirements for Houses in Multiple Occupation (HMOs) and short-term rental properties (e.g. Airbnb, serviced accommodation).

New requirements may include:

• Annual safety declarations confirming that electrical systems remain safe.
• Mandatory interlinked smoke alarms and carbon monoxide detectors in all sleeping and living areas.
• More frequent EICR inspections for HMOs with more than 5 occupants (every 3 years instead of 5).

Check with your borough council for their specific licensing scheme. Many now require you to upload proof of electrical compliance as part of your landlord licensing application or renewal.

3. Smart Meters and Energy Efficiency Standards

While not a legal requirement yet, energy efficiency standards are tightening. Most London landlords now voluntarily install smart meters to help tenants manage usage and improve EPC (Energy Performance Certificate) ratings.

In the near future, meeting EPC Band C may become mandatory—making upgraded electrics, LED lighting, and modern fuse boards essential for compliance and tenant appeal.

4. Appliance Testing (PAT) – Still Best Practice

Though not legally required for all rentals, Portable Appliance Testing (PAT) is recommended if you provide any electrical appliances (e.g., kettles, microwaves, washing machines).

• PAT testing ensures these appliances are safe to use.
• It demonstrates your commitment to tenant safety.
• It could protect you in case of a legal claim.

5. Legal Penalties for Non-Compliance (Don’t Risk It)

Failing to meet electrical safety obligations can lead to:

• Fines of up to £30,000
• Inability to serve a Section 21 eviction notice
• Legal claims from tenants for damages or injury
• Void landlord insurance in case of fire or electrical failure

Don’t wait for a council inspection or tenant complaint. Proactive maintenance and certification save money—and reputations.

6. Working with Certified Electricians Matters

To be valid, all inspections must be carried out by someone registered with a recognised scheme like:

• NICEIC
• NAPIT
• ECA

At Lumiel, we're proud to be NICEIC-approved and offer all necessary landlord services under one roof—from EICRs and remedials to smoke detector installation and full rewires.
