If you rent out a property with gas appliances, gas safety is something you cannot ignore. A valid Gas Certificate London gives you a clear record that the required checks have been carried out by a Gas Safe registered engineer.
For landlords, annual gas safety checks are a legal duty for gas appliances and flues that they provide for tenants. The check also helps find problems that could put people at risk.
This guide explains what the certificate covers, how often you need one and what to do after the inspection.
What Is a Gas Certificate London?
The term Gas Certificate London is commonly used to describe a Landlord Gas Safety Record, often called a CP12. It is issued after a Gas Safe registered engineer carries out the required safety checks at the property.
The record normally includes the appliances and flues checked, the property address, the inspection date, the engineer’s details and any safety defects found.
If you need to arrange an inspection, see our Gas Safety Certificate (CP12) service.

| Cooker Inspection | Cooker leak and connection check | £50-£90 |
| Fire Inspection | Gas fire and pipework inspection | £60-£100 |
| Pipework Check | Full inspection of pipes and ventilation | £40-£80 |

Who Needs a Gas Safety Certificate?
Landlords must arrange an annual gas safety check for gas appliances and flues they provide for tenants.
The Health and Safety Executive explains that these checks must be carried out every year.
This makes an up-to-date gas safety record especially important for landlords, letting agents and property managers responsible for rented homes with gas appliances.
Homeowners are not covered by the same landlord duties, but regular gas checks and servicing are still sensible.
How Long Does a Gas Certificate London Last?
For a rented property, the gas safety check must be carried out every year.
Landlords can arrange the next check during the two months before the due date and, when the legal conditions are met, keep the existing annual renewal date.
This can make it easier to organise access without leaving the check until the last minute.
If your Gas Certificate London renewal is coming up, booking early gives you more time to arrange access with the tenant and deal with any issues found.
What Does the Gas Safety Check Cover?
The exact checks depend on the appliances and gas installation at the property.
A Gas Safe registered engineer may check:
- Gas boilers
- Gas cookers or hobs
- Gas fires
- Flues
- Relevant gas fittings and connections
- Safe operation of the appliances
The purpose of the inspection is to check gas safety, not simply to produce paperwork.
If the property needs a new heating system rather than a routine gas check, see our Boiler Installation service.
Does a Gas Safety Certificate Include a Boiler Service?
Not necessarily.
A gas safety check and a boiler service are related, but they are not the same job.
A gas safety check focuses on whether the appliance is safe to use. A boiler service is a more detailed maintenance visit and can include checks based on the boiler manufacturer’s instructions.
If you want a boiler service at the same time as your Gas Certificate London inspection, make sure you request both when booking.
Who Can Issue a Gas Certificate London?
A Gas Certificate London must be issued following a check carried out by a Gas Safe registered engineer who is qualified for the type of gas work involved.
You can check an engineer or business through the official Gas Safe Register.
Do not choose someone only because they offer a cheap gas certificate. Always check that they are properly registered and qualified for the appliance they are working on.
What Must Landlords Give to Tenants?
After the annual gas safety check, landlords must give the gas safety record to existing tenants within 28 days.
A new tenant must receive a copy before they move into the property.
The HSE also states that landlords must keep gas safety check records for at least two years.
You can read more in the official HSE gas safety guidance for landlords.
Keeping each certificate organised makes Gas Certificate London renewals much easier, especially if you manage several properties.
What Happens If the Engineer Finds a Problem?
A gas safety inspection can identify faults that need attention.
What happens next depends on the issue and how serious it is.
Do not ignore a fault because you were expecting a certificate that day. If the engineer says an appliance is unsafe, follow their advice and arrange the required repair before it is used again.
The aim of a Gas Certificate London inspection is to protect the people using the property, not simply to complete a yearly form.
For business premises, you may need a different type of inspection. See our Commercial Gas Safety Certificate service.
Gas Certificate London and Other Landlord Checks
A gas safety certificate only covers gas safety. It does not replace other property inspections.
Depending on the property, landlords may also need an EICR to check the electrical installation.
You may also need an Energy Performance Certificate for the property’s energy rating.
Keeping your gas, electrical and energy records together can make property management easier and reduce the chance of missing an important renewal.
How to Prepare for a Gas Safety Inspection
A little preparation can make your Gas Certificate London appointment easier.
Make sure the engineer can access:
- The gas meter
- The boiler
- Gas cookers or hobs
- Gas fires
- Any other gas appliance that needs to be checked
If a tenant lives at the property, confirm the appointment with them in advance.
It also helps to keep your previous gas safety record available so you can check the last inspection date.
If you manage several properties, keep a simple list showing the property address, inspection date and next renewal date.
