Introduction

For landlords in Surrey — especially in Molesey, Walton-on-Thames and surrounding areas — keeping rental properties safe is a legal responsibility. A Gas Safety Certificate (CP12) inspection is required every 12 months for any property with gas appliances.
But what should you do if your CP12 fails? This guide explains the process clearly and shows how to remain fully compliant.

1. Understanding a Failed Gas Safety Certificate

During a CP12 inspection, a Gas Safe engineer checks your:

• Gas boiler
• Gas hob or cooker
• Flues
• Pipework
• Ventilation

If faults are found, your CP12 will highlight them under two categories:

Minor Faults

These are not immediately dangerous but must be repaired to stay compliant.

Immediately Dangerous (ID)

These faults pose a serious risk. The appliance must be switched off and taken out of use immediately.

Local insight:
In many Surrey rental homes, particularly older properties in Molesey and Walton, ageing boilers often present minor issues. Regular servicing helps reduce the chance of CP12 failures.

2. Legal Responsibilities for Landlords in Surrey

Failing to act quickly after a CP12 failure carries significant consequences:

Criminal Liability

Allowing tenants to use unsafe appliances breaches the Gas Safety (Installation and Use) Regulations 1998.

Civil Liability

If a tenant is harmed or property damage occurs, you may face legal claims.

Insurance Complications

Many insurers will refuse claims if the property has unresolved gas safety issues.

Enforcement Action

The HSE or local council can investigate and take action against non-compliant landlords.

3. Tenant Rights in Molesey and Walton-on-Thames

Tenants must be provided with a safe home. If an appliance is unsafe:

• They can report the property to the HSE
• They can ask local councils to intervene
• In severe cases, they may seek legal advice or withhold rent

Being proactive helps maintain trust and avoid escalation.
