Landlord Safety Certificates: Gas (CP12) and EICR — 2026 Complete Guide

UK landlords are legally required to hold two core safety certificates: a gas safety certificate (CP12) and an Electrical Installation Condition Report (EICR). Both protect your tenants, both protect you legally, and both carry serious penalties if missed. This guide covers everything you need to know about each one.

At LWR Group, we coordinate both gas safety and EICR inspections for landlords and letting agents across Lincoln and Lincolnshire. One point of contact, one invoice, no chasing separate trades.

Part 1: Gas Safety Certificate (CP12)

What is a landlord gas safety certificate?

A gas safety certificate, officially called a Gas Safety Record or CP12, is a legal document issued by a Gas Safe registered engineer after an annual inspection of all gas appliances, pipework, and flues in a rental property. It confirms every gas installation is safe to use.

It is a legal requirement under the Gas Safety (Installation and Use) Regulations 1998. It cannot be self-issued — only Gas Safe registered engineers can carry out the inspection and sign off the certificate.

What does the CP12 inspection cover?

How often do you need a landlord gas safety certificate?

Every 12 months. The certificate expires exactly 12 months after the inspection date. You must provide a copy to tenants within 28 days of inspection, and to any new tenant before they move in. Keep records for at least 2 years.

How much does a landlord gas safety certificate cost?

For most rental properties, a CP12 costs £65 to £110 in 2026. Prices vary by number of appliances, location, and whether you combine it with a boiler service.

Penalties for not having a gas safety certificate

• Fines of up to £6,000 per offence at Magistrates Court
• Unlimited fines at Crown Court for serious cases
• Up to 6 months imprisonment for the most serious breaches
• Inability to serve a valid Section 21 eviction notice
• Potential invalidation of landlord insurance
• Criminal prosecution if a tenant is harmed due to unsafe gas

Part 2: EICR (Electrical Installation Condition Report)

What is an EICR certificate?

An EICR is the electrical equivalent of the CP12. A qualified electrician inspects and tests all fixed electrical installations in the property — wiring, sockets, fuse board, and associated fittings — and issues a report grading their condition.

The report classifies each item as Satisfactory or Unsatisfactory. Individual issues are coded C1 (danger — immediate action required), C2 (potentially dangerous), C3 (improvement recommended), or FI (further investigation required). Any C1 or C2 code means the overall report is Unsatisfactory and remedial work must be completed within 28 days.

Is an EICR a legal requirement for landlords?

Yes — in England, under the Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020. The requirement applies to new tenancies from 1 July 2020 and all existing tenancies from 1 April 2021.

How much does a landlord EICR cost?

Penalties for not having a valid EICR

• Financial penalty up to £30,000 per breach, issued by the local authority
• Local authority can carry out remedial work and recover costs from the landlord
• Inability to serve a valid Section 21 eviction notice
• Potential invalidation of landlord insurance
• Civil claims from tenants if they suffer injury or loss from an unsafe installation

Gas safety certificate vs EICR — key differences

Common questions

Do I need both a gas safety certificate and an EICR?

Yes, if your property has gas. You need an annual CP12 for gas and a 5-yearly EICR for electrics. If your property is all-electric (no gas supply), you only need the EICR.

Can my tenant refuse access for an inspection?

For gas safety, you must make reasonable attempts to gain access and document every attempt in writing. If access is persistently refused, you can apply to court for an access order. The same principle applies to EICR. Document everything — letters, emails, texts — in case of dispute.

What happens if my EICR comes back unsatisfactory?

Any C1 or C2 codes mean the report is Unsatisfactory. You must complete the required remedial work within 28 days (or the timeframe specified in the report if shorter). Get written confirmation from the electrician and provide it to tenants and the local authority within 28 days.

Does a new boiler mean I don't need a CP12?

No. A new boiler comes with a Benchmark commissioning certificate but that is not a CP12. You still need a separate annual gas safety inspection covering all gas appliances in the property.

Are these certificates required in Scotland, Wales, or Northern Ireland?

The Gas Safety Regulations 1998 apply across the UK — you need a CP12 everywhere. The Electrical Safety Standards 2020 (EICR requirement) apply to England only. Scotland has its own equivalent rules under the Housing (Scotland) Act 2006. Wales and Northern Ireland have separate regulations.
