At Eden Mechanical & Electrical, we believe safety isn’t just a box to tick it’s essential for protecting people, property, and peace of mind.

One of the most important ways to ensure your home or rental property is safe and compliant is through a Gas Safety Check (Gas Safety Certificate, also known as a CP12). But what exactly is it, and who needs one?

In this post, we’ll cover:

  • What a Gas Safety Certificate involves

  • Who is legally required to get one

  • How often they should be carried out

  • Why Eden Mechanical & Electrical’s Gas Safe engineers in Hertfordshire are the trusted choice for compliance and peace of mind

What Is a Gas Safety Certificate?

A Gas Safety Certificate (sometimes called a CP12) is a formal record confirming that a property’s gas appliances, flues, and pipework have been inspected and deemed safe. It’s designed to:

  • Identify any gas leaks or safety hazards

  • Check that appliances are operating efficiently and safely

  • Ensure compliance with the Gas Safety (Installation and Use) Regulations 1998

  • Recommend any remedial action if needed

Only a qualified Gas Safe–registered engineer can carry out these checks  like the experts at Eden Mechanical & Electrical.

Who Needs a Gas Safety Certificate?

Landlords (Legal Requirement)

Since 1996 all landlords in the UK must arrange an annual landlord gas safety check for every rental property. This includes:

  • Inspection of all gas appliances flues and pipework

  • Issuing a Gas Safety Record (CP12) every 12 months

  • Providing tenants with a copy within 28 days

  • Keeping records for a minimum of 2 years

Non compliance can result in heavy fines and even imprisonment.

Homeowners

Although homeowners aren’t legally required to get a Gas Safety Certificate it’s strongly advised to book a yearly gas safety check:

  • As part of regular maintenance

  • When buying or selling a property

  • If you suspect a fault with an appliance

Businesses & Commercial Properties

Employers and commercial landlords must ensure that all gas appliances in their premises are safe and compliant. An annual commercial gas safety inspection demonstrates due diligence and helps avoid legal penalties while protecting staff and visitors.
