What a CP12 Covers
A gas safety certificate, often called a CP12, is issued after a Gas Safe registered engineer checks the gas appliances and gas supply in a property. It is essential for landlords and useful for homeowners who want peace of mind.
- Boiler safety and flue checks
- Gas hob, cooker and fire checks where present
- Gas meter and emergency control valve checks
- Visible gas pipework inspection
- Ventilation and appliance safety checks
- Certificate issued after the inspection
For Landlords, Agents and Homeowners
Landlords must keep gas safety records up to date for rented properties. We work with private landlords, tenants and managing agents across London, including flats, HMOs and managed buildings.
Arrange Access
We agree a time and confirm appliance locations before attending.
Carry Gas Safe ID
The engineer attends with Gas Safe registration details available to check.
Complete The Inspection
Each appliance is checked and recorded according to current safety requirements.
Issue The Record
The certificate is issued after the check, with any remedial advice explained clearly.
If Something Fails
If an appliance is unsafe, we explain what has failed and what needs to happen next. Safety comes first. Where a repair is practical, we can advise on the next step without confusing jargon.
Emergency Plumbing Questions
Can I book a gas safety check at short notice?
Often, yes. Call with the area, property type and access details and we will give the earliest realistic appointment.
Does the tenant need to be present?
Someone needs to provide access to the boiler, meter and any gas appliances. That can be the tenant, landlord, agent or authorised key holder.
Do homeowners need a gas safety certificate?
It is not a legal requirement for owner-occupiers, but an annual gas safety check is a sensible way to keep appliances safe.
