Gas Safety Certificates
Gas Safety Certificates (CP12) for Landlords in Kent and South East London
Legal. Essential. Same-Day Certificates Issued.
CP12 Gas Safety Certificates — Issued Same Day
If you rent out a property with gas appliances in Kent or South East London, a valid gas safety certificate is not optional — it is a legal requirement. The Gas Safety (Installation and Use) Regulations 1998 require landlords to arrange a gas safety check for every gas appliance and flue in their rental property, every 12 months, carried out by a Gas Safe registered engineer.
BoilerSense provides gas safety certificates across Kent and South East London for residential and commercial landlords. Certificates are issued on the day of inspection. Our Gas Safe registered engineers cover DA1, DA2, DA5, DA6, DA7, DA11, DA12, DA14, DA15, SE18, SE10, and SE3 postcode areas.

A CP12 — Landlord Gas Safety Record — is the official document issued after a Gas Safe registered engineer has inspected all gas appliances, pipework, and flues in a rented property and confirmed they are safe to use.
The term "CP12" derives from the old CORGI inspection form numbering. Despite CORGI being replaced by the Gas Safe Register in 2009, the CP12 terminology remains widely used.
The certificate records the following information:
The address of the property inspected
Details of all gas appliances and flues inspected, and whether each was deemed safe, immediately dangerous, or at risk
The Gas Safe registration number of the engineer who carried out the inspection
The date of inspection and the date the certificate expires — always 12 months from inspection
You must provide a copy to each tenant within 28 days of the check, and to any new tenant before they move in.
Who Legally Needs a Gas Safety Certificate?
Gas safety certificates are a legal requirement for a range of landlord and property management situations across England.
Private Landlords
All private landlords in England, Scotland, and Wales who rent properties containing gas appliances must hold a valid CP12 for each property. The requirement applies whether the property is furnished or unfurnished, rented on an Assured Shorthold Tenancy or any other basis.
Letting Agents
Where a letting agent manages a property on behalf of a landlord, the responsibility for the gas safety check can be contractually transferred to the agent. We can arrange scheduled inspections across your portfolio across Kent and South East London.
HMO Owners
HMOs have additional licensing requirements, and gas safety compliance is scrutinised more closely. All gas appliances in HMOs require annual certification — the inspection process is the same as for standard properties.
Commercial Property Owners
Businesses, offices, and commercial premises with gas appliances also require annual gas safety inspections. We issue commercial gas safety certificates as well as residential CP12s.
The Consequences of Non-Compliance
The legal penalties for failing to hold a valid gas safety certificate are serious — and the practical risks are far greater.
Legal Penalties
- Fines of up to £6,000 per appliance or flue not covered by a valid certificate
- Up to 6 months imprisonment for deliberate non-compliance
- Inability to serve a valid Section 21 notice until the certificate is in place
- Civil liability if a tenant or occupant is injured as a result of a gas safety failure
Practical Safety Risk
Beyond the legal consequences, the practical risk is substantial. A faulty boiler or gas appliance in a rental property can cause carbon monoxide poisoning, gas explosions, or fires.
The annual gas safety inspection is not bureaucratic overhead — it is the mechanism that identifies dangerous conditions before they cause harm. It protects your tenants and your legal position simultaneously.
What a BoilerSense Gas Safety Inspection Covers
A thorough inspection of all gas appliances, pipework, flues, and safety systems in the property.
After the inspection, the engineer records the findings for each appliance and issues the CP12 certificate. If any appliance is found to be unsafe, the engineer will advise on the required action and, if an appliance presents an immediate danger, will disconnect it from the gas supply.

Same-Day Certificates — How It Works
We understand that landlords frequently face time pressure. BoilerSense issues gas safety certificates on the day of inspection, not days later.
Book Your Inspection
Call 01474 632 158 or email enquiries@boilersense.co.uk. Tell us the address, number of gas appliances, and when you need the inspection carried out.
Engineer Attends
A Gas Safe registered BoilerSense engineer arrives at the agreed time, introduces themselves to your tenant (if applicable), and carries out the inspection.
Inspection Carried Out
Typically 30–45 minutes for a standard property with a boiler and hob. The engineer inspects all gas appliances, pipework, and flues in the property.
Certificate Issued Same Day
Both a digital and paper copy of the CP12 are issued before the engineer leaves. You have the documentation you need the same day — no waiting, no chasing.
Important Landlord Information
Key obligations you need to be aware of as a landlord with gas appliances in rental properties.
Tenant Copy Requirements
You must give a copy of the gas safety record to:
- Existing tenants — within 28 days of the inspection
- New tenants — before they move in (not within 28 days; before they move in)
Keeping records of when you provided copies to tenants is advisable in case of a future dispute.
Record Keeping
Landlords must keep a copy of each gas safety record for a minimum of two years from the date of the inspection.
We provide digital copies alongside paper certificates, making it straightforward to maintain your compliance records.
Early Renewal Allowance
You can have your gas safety inspection carried out up to two months before the current certificate expires without losing the renewal date. A certificate expiring on 15 June can be renewed any time from 15 April — the new certificate will still run to 15 June the following year.
New Tenancies
For new tenancies beginning from 1 July 2020 onwards, landlords must give tenants a valid gas safety certificate before the tenancy begins. This is not a grace period obligation — it applies from day one of the tenancy.
Landlords With Multiple Properties
We work with a number of landlords managing multiple properties across Kent and South East London. If you own or manage three or more properties, we can offer:
Reduced per-property rates for bulk bookings across your portfolio.
We track your renewal dates and contact you when an inspection is due — so you never let a certificate lapse.
Where appropriate, we can combine the annual boiler service and gas safety inspection in a single visit, reducing cost and tenant disruption.

CP12 vs Boiler Service — What Is the Difference?
These are frequently confused but are different things:
A gas safety certificate (CP12) is a legally required landlord document confirming appliances are safe to use. It is a compliance document, not a maintenance record.
A boiler service is preventive maintenance — cleaning, calibrating, and checking the boiler to keep it running efficiently and to maintain the manufacturer warranty.
Both are important for rental properties. Where practical, we can carry out both in a single visit — ask us about combined inspection and service packages.
