Landlord CP12 & Homeowner Checks
Gas Safety Certificates in Maidstone — Landlord CP12 & Homeowner Checks
From £80. Legal requirement for every rental property with gas appliances, renewed annually. Gas Safe registered engineers, digital certificates issued same day.
What Is a CP12?
The Landlord Gas Safety Certificate
If you're a landlord in Maidstone, a valid gas safety certificate is not optional — it's a legal requirement under the Gas Safety (Installation and Use) Regulations 1998. Every rental property with gas appliances must be inspected by a Gas Safe registered engineer every 12 months.
Failure to comply carries serious consequences: unlimited fines, up to two years imprisonment, and the potential invalidation of your landlord insurance.
The CP12 Certificate Records:
- Property address and landlord details
- Description and location of each gas appliance inspected
- Results of each safety check (pass/fail per appliance)
- Any defects or safety issues identified
- Remedial action required (and appliance status)
- Engineer's Gas Safe registration number and signature
- Date of inspection

Legal Obligations
The Legal Requirements for Landlords
Annual inspection
Every rental property with gas appliances must be inspected annually by a Gas Safe registered engineer. There are no exemptions based on appliance age or condition.
Certificate must be current
A gas safety certificate that has expired — even by a day — means you are operating without legal compliance. The inspection must be carried out before the old certificate expires.
Tenant copy within 28 days
You must provide a copy of the certificate to any existing tenant within 28 days of the inspection. New tenants must receive a copy before they move in, not after.
Two-year record retention
Landlords must keep records of every gas safety certificate for at least two years.
Penalties for non-compliance
Unlimited fines, up to two years imprisonment per offence, and potential prosecution by the Health and Safety Executive. Most landlord insurance policies require a valid CP12 as a condition of cover.
The Two-Month Early Renewal Rule
One practical detail many landlords miss: you can carry out the gas safety inspection up to two months before the certificate expires and still keep the same renewal date.
Example: Your CP12 expires on 30 September. You can have the inspection carried out any time in August and the new certificate will show an expiry of 30 September next year — you haven't lost the two months.
This matters for scheduling. If your tenant is difficult to access, or you want to coordinate the gas safety check with other maintenance, the two-month window gives you flexibility.
Homeowner Gas Safety Checks
Gas safety inspections aren't just for landlords. Homeowners can also benefit from having a Gas Safe engineer inspect their appliances and pipework — particularly:
- When buying a property without a recent inspection record
- If you're concerned about an appliance that has developed a smell or unusual behaviour
- Before letting a property you previously occupied
A homeowner check is carried out to the same standard as a landlord inspection and gives you written confirmation that your appliances are safe.
Pricing
Gas Safety Certificate Cost in Maidstone
A landlord gas safety certificate (CP12) in Maidstone costs from £80 for a property with one or two gas appliances (typically boiler plus gas hob). Additional appliances (gas fire, second boiler, separate gas cooker) are charged per appliance.
We can also combine the gas safety inspection with an annual boiler service on the same visit — more cost-effective than two separate appointments and your tenant only needs to provide access once.

Managing Multiple Properties
If you're a landlord with more than one property in the Maidstone area, we can coordinate inspections to minimise disruption:
- Schedule multiple properties on the same day where possible
- Work directly with your tenants to arrange access
- Send reminder calls as certificates approach renewal date
- Issue all certificates digitally for a permanent record
Carbon Monoxide Alarms: A Legal Requirement for Landlords
Under the Smoke and Carbon Monoxide Alarm (England) Regulations 2015 (updated 2022), landlords are legally required to install an audible carbon monoxide alarm in every room that contains a fuel-burning appliance — including rooms with gas boilers.
The alarm must be tested and confirmed working at the start of each new tenancy. Failure to comply results in fines up to £5,000 per property.
We check CO alarm presence and function as part of our inspection and will note any missing or non-functioning alarms in the certificate. We carry replacement alarms if needed.
