CP12 Legal Requirements in Berkshire and Middlesex for Landlords

Guide

Landlords are responsible for ensuring annual gas safety checks are completed on relevant appliances and systems in rented properties.

A valid CP12 record supports legal compliance and demonstrates that required checks on appliances, flues, and ventilation were carried out.

Missed renewal windows can create avoidable compliance risk, so many landlords use scheduled reminders and portfolio-wide booking plans.

Good record management matters as much as inspection itself. Keep certificates and remedial work records organised for tenancy and audit purposes.

Where access difficulties occur, document communication attempts and rebooking actions clearly to maintain a defensible compliance trail.

Using a consistent annual process helps landlords reduce stress, avoid gaps, and keep tenant safety standards aligned across properties.

Quick Checks Before Booking

A few simple checks can make your appointment faster and help your engineer diagnose the issue more efficiently on arrival.

• Note any boiler error codes or warning lights before calling.
• Check whether the issue affects heating, hot water, or both.
• Keep the area around the boiler clear for safe engineer access.

What to Share When You Book

• Property address and best contact number
• Boiler make/model if available
• When the fault started and how often it occurs

Having this information ready can reduce back-and-forth and help schedule the right visit first time.
