A Gas Safety Certificate, officially known as a Landlord Gas Safety Record (LGSR), is a legal document that confirms gas appliances and fittings in a property have been checked and are safe to use.
In the UK, gas safety checks must be carried out by a Gas Safe registered engineer to ensure appliances such as boilers, gas fires, and cookers do not pose a risk to occupants.

What Is a Gas Safety Certificate?
A Gas Safety Certificate, officially known as a Gas Safety Record, confirms that gas appliances and installations in a property have been inspected by a Gas Safe registered engineer.
The certificate shows that:
- Gas appliances are working safely
- There are no dangerous leaks
- Ventilation is adequate
- Safety devices are functioning correctly
It is issued after a successful gas safety inspection.
Who Needs a Gas Safety Certificate?
Landlords are legally required to have a valid gas safety certificate for:
- All rental properties with gas appliances
This applies to:
- Houses
- Flats
- HMOs
- Social and private rented accommodation
Homeowners
Homeowners are not legally required to have a gas safety certificate unless they are renting out the property.
However, annual gas safety checks are strongly recommended for safety reasons.
When Is a Gas Safety Certificate Required?
A gas safety certificate is required:
- Before a tenant moves in
- Every 12 months during a tenancy
- When gas appliances or pipework are installed or replaced
Landlords must:
- Provide a copy to tenants within 28 days of the check
- Give new tenants a copy before they move in.
How Often Is a Gas Safety Certificate Required?
A gas safety certificate must be renewed every 12 months.
You can carry out the inspection:
- Up to 2 months before expiry
- Without changing the renewal date
This helps landlords stay compliant without gaps in coverage.
What Is Checked During a Gas Safety Inspection?
During a gas safety inspection, the engineer will check:
- Gas boilers
- Gas cookers and hobs
- Gas fires
- Gas pipework
They will look for:
- Gas leaks
- Unsafe pressure levels
- Faulty safety devices
- Inadequate ventilation
- Carbon monoxide risks
Only engineers registered with Gas Safe are legally allowed to carry out these checks.
What Information Is Included on a Gas Safety Certificate?
A gas safety certificate includes:
- Property address
- Date of inspection
- Details of appliances checked
- Test results
- Any faults identified
- Actions required (if any)
- Engineer’s Gas Safe registration number
The certificate must be kept as proof of compliance.
How Much Does a Gas Safety Certificate Cost?
Typical gas safety certificate costs in the UK are:
| Property Type | Average Cost |
|---|---|
| Flat (1 appliance) | £50 – £80 |
| House (2–3 appliances) | £70 – £120 |
| HMO / multiple appliances | £100 – £200+ |
Prices vary depending on:
- Number of appliances
- Property size
- Location
The inspection usually takes 30 to 60 minutes. Tip: Many engineers offer discounts if combined with a boiler service.
What Happens If You Don’t Have a Gas Safety Certificate?
Failing to have a valid gas safety certificate when required can lead to serious consequences.
For landlords, penalties can include:
- Fines of up to £6,000 per breach
- Criminal prosecution
- Invalidation of landlord insurance
- Inability to serve a Section 21 notice
In severe cases, landlords may face imprisonment.
Can You Rent a Property Without a Gas Safety Certificate?
No. It is illegal to rent out a property with gas appliances without a valid gas safety certificate.
Letting agents cannot legally market the property, and tenants should not be allowed to move in without one.
Failing to comply with safety and energy efficiency rules can lead to fines and enforcement action.
Gas Safety Certificate vs EPC: What’s the Difference?
| Certificate | Purpose | Validity |
|---|---|---|
| Gas Safety Certificate | Gas appliance safety | 12 months |
| EPC (Energy Performance Certificate) | Energy efficiency rating | 10 years |
Landlords usually need both when renting out a property.
What If a Property Has No Gas?
If a property:
- Has no gas supply, or
- Has no gas appliances
Then a gas safety certificate is not required.
However, landlords should be able to demonstrate that the property genuinely does not have gas.
What Happens If an Appliance Fails the Gas Safety Check?
If an appliance is found to be unsafe:
- It may be labelled as dangerous
- It may be disconnected
- Repairs may be required before the certificate can be issued
A gas safety certificate will not be issued until all safety issues are resolved.
Can You Use an Existing Gas Safety Certificate?
No. Gas safety certificates:
- Are valid for 12 months only
- Cannot be reused beyond their expiry date
A new inspection is required each year, even if no changes have been made.
Do Tenants Have Responsibilities?
Tenants are responsible for:
- Allowing access for inspections
- Reporting gas safety concerns
Landlords should keep records of:
- Inspection attempts
- Tenant communication
This helps demonstrate compliance if access is refused.
