Gas Safety Certificates in Medway
If you are a landlord with rental properties in Medway, a gas safety certificate is not optional — it is a legal requirement. Every gas appliance in your rental property must be checked annually by a Gas Safe registered engineer, and a Gas Safety Record (commonly known as a CP12 certificate) must be issued and provided to your tenants within 28 days.
What Is a Gas Safety Certificate?
A Gas Safety Record, commonly referred to as a gas safety certificate or CP12, is a document that confirms all gas appliances, pipework, and flues in a property have been inspected and are safe to use. The check is carried out by a Gas Safe registered engineer and covers every gas appliance in the property.
Who Needs a Gas Safety Certificate?
- Landlords (Legal Requirement) Under the Gas Safety (Installation and Use) Regulations 1998, landlords in England and Wales must arrange a gas safety check on every gas appliance in their rental properties once every 12 months. This applies to all types of rental property, including single lets, houses in multiple occupation (HMOs), and properties managed through letting agents. Failure to comply is a criminal offence, carrying potential fines of up to £6,000, a prison sentence of up to six months, or both.
- Homeowners (Recommended) While homeowners are not legally required to obtain a gas safety certificate, an annual gas safety check is strongly recommended. It confirms that your gas appliances are burning correctly, there are no gas leaks, and there is no risk of carbon monoxide poisoning. Carbon monoxide is odourless and colourless, and claims around 30 lives in the UK each year.
- Property Sellers A gas safety certificate is not a legal requirement when selling a property, but most buyers and their solicitors expect to see a valid certificate as part of the conveyancing process. Having a current certificate avoids delays and demonstrates that the property’s gas installations are safe.
What Is Checked During a Gas Safety Inspection?
Our engineer inspects every gas appliance in the property. The check includes:
- Gas boiler Combustion analysis, flue integrity, ventilation, gas pressure, safety devices, and visual inspection for leaks or corrosion.
- Gas fire Flame picture, flue draw, ventilation, and spillage test.
- Gas cooker and hob Burner operation, flame failure devices, gas tightness, and stability.
- Gas pipework Visual inspection of accessible pipework for corrosion, damage, or signs of gas leaks.
- Flues and ventilation Checking that flues are clear and correctly terminated, and that ventilation to each appliance meets current standards.
- Meters and emergency controls Confirming that the gas meter and emergency control valve are accessible and in good condition.
