What a CP12 Coversand Why It Is Not Optional
A landlord gas safety record, commonly called a CP12, is an annual inspection of the gas appliances, flues and installation pipework in a rented property, carried out by a Gas Safe registered engineer. It is a legal obligation for landlords in England and Wales, and it must be renewed within 12 months of the previous inspection.
The inspection checks each appliance for gas tightness, correct operation, adequate ventilation, satisfactory flue performance and safe combustion where applicable, and records the outcome on a certificate that you must give to your tenants and keep on file.
Rusupo Heating and Plumbing Ltd is Gas Safe registered under registration 638860, covering domestic gas pipework, boilers, vented and unvented cylinders, water heaters, cookers, range cookers, fires and combustion analysis. That full scope means a property with a boiler, a gas hob and a gas fire can be certified in one visit by one engineer.
Why professional help matters
- Only a Gas Safe registered engineer can carry out the inspection and issue a valid record, no one else's paperwork counts.
- Combustion and flue performance cannot be assessed visually; the checks require instruments and competence.
- The inspection scope must cover every gas appliance and the installation pipework, not just the boiler.
- Records must be issued to tenants and retained; incomplete documentation is a compliance failure even when the appliances are safe.
Who this is for
- Landlords with one property or a small portfolio across Essex and Suffolk
- Letting agents arranging annual compliance on behalf of owners
- Landlords who have inherited a property with no documented gas safety history
- Owners preparing a property for a new tenancy
- Anyone whose renewal date is approaching and needs it booked cleanly around tenants
When it is needed
- Annually, within 12 months of the last inspection date
- Before a new tenancy begins, so the certificate can be issued to tenants at the start
- After any new gas appliance is installed in the property
- When taking over management of a property with incomplete records
- Alongside the annual boiler service, to keep everything on one schedule
The cost of waiting
What Happens If theCertificate Lapses
A lapsed gas safety record is a legal problem before it is a safety problem. Landlords have a duty to have appliances and flues checked annually and to provide the record to tenants. Falling behind puts you in breach of that duty, and the paper trail is exactly what gets examined when anything else goes wrong.
The safety issue is the real one. Faulty appliances, blocked flues and inadequate ventilation produce carbon monoxide, which tenants cannot detect. Annual inspection with combustion analysis exists specifically because this hazard gives no warning, and because tenants are relying on someone else to check on their behalf.
There is also a practical consequence. Renewals left to the last week collide with tenant availability, access arrangements and engineer schedules. Booking in good time means a single appointment at a convenient hour rather than chasing access while the certificate expires.
Common mistakes we see
- Treating a boiler service as if it were a gas safety certificate, they are different things
- Forgetting appliances beyond the boiler, such as a gas hob, fire or range cooker
- Letting the renewal date drift and then struggling with tenant access
- Failing to give tenants a copy of the record and keep one on file
- Using someone who is not Gas Safe registered, which makes the certificate worthless

In detail
Landlord Gas Safety Certificates (CP12)Explained Properly
What is inspected on a gas safety check
Each appliance is checked for gas tightness, correct operating pressure and heat input, satisfactory ventilation, and safe flue performance. Where applicable, combustion is measured with a flue gas analyser to confirm the appliance is burning within specification.
The installation pipework and the emergency control valve are also examined, along with the accessibility and condition of the meter arrangement. Safety devices on appliances are tested to confirm they operate.
The outcome for each appliance is recorded on the certificate, along with any defects identified and the action taken. Where an appliance is classified as unsafe, that is explained clearly at the time, not left for you to interpret from paperwork afterwards.
CP12 versus a boiler service
These are frequently confused. A gas safety record confirms that appliances and the installation are safe on the day of inspection, and it is a landlord's legal obligation. A boiler service maintains the appliance itself: cleaning, component checks, and the documented record that manufacturers require to keep a warranty valid.
One does not substitute for the other. A property can hold a valid CP12 while the boiler has not been serviced for years, and an unserviced boiler under warranty is an appliance with no warranty in practice.
For rented properties we generally recommend doing both in the same visit. It is one appointment for the tenant, one set of travel, and it puts the service and the certificate on the same annual cycle so nothing drifts.
Appliances beyond the boiler
The certificate must cover every gas appliance in the property, which in practice often means more than the boiler. Gas hobs and cookers, range cookers, gas fires and gas water heaters all fall within scope, and our Gas Safe registration explicitly covers cookers, range cookers, fires, water heaters and cylinders.
Appliances the tenant owns are a common grey area. The landlord's duty covers the appliances and flues the landlord provides, plus the installation pipework, and we will make clear on the day what has been inspected and what falls outside scope.
Where an appliance is found unsafe, it is dealt with according to the relevant industry procedure, explained to you and the tenant, and quoted for repair or replacement with a fixed price.

Questions
Landlord Gas Safety Certificates (CP12)Questions Answered
Something not covered here? Call 07984 042373: the 24-hour line is usually answered personally by Matt.
How much is a landlord gas safety certificate?
It is quoted as a fixed price for your property, based on the number of gas appliances. Ask by phone or through the form and you will have a figure before booking. Combining it with the annual boiler service is usually the more economical route.
How often do I need a CP12?
Annually. The inspection must be carried out within 12 months of the previous one, and the record must be given to your tenants and kept on file.
How long does the inspection take?
For a typical property with a boiler and one or two other appliances, it is usually well under an hour. Larger properties with more appliances take proportionately longer.
What is checked during the inspection?
Gas tightness, operating pressure, ventilation, flue performance, safe operation of each appliance and its safety devices, and the installation pipework, with combustion analysis where applicable.
Is a CP12 the same as a boiler service?
No. A CP12 confirms safety at the date of inspection and is a legal landlord requirement. A service maintains the appliance and satisfies manufacturer warranty conditions. We can do both in one visit.
Do you arrange access with the tenant?
Yes. Give us the tenant's details and we will arrange a workable time directly with them, so you are not caught in the middle of scheduling.
What happens if an appliance fails the check?
We explain the classification and the reason clearly to you and the tenant, deal with it according to the correct procedure, and give you a fixed price to repair or replace it so it can be resolved quickly.
Which appliances are covered?
All the gas appliances in the property, which typically means the boiler plus any hob, cooker, range cooker, fire or gas water heater. Our registration 638860 covers all of these, plus vented and unvented cylinders and installation pipework.
Do you cover Braintree and Colchester for CP12s?
Yes, along with Kelvedon, Tiptree, Feering, Halstead, Sudbury, Sible Hedingham, Coggeshall and the surrounding Essex and Suffolk villages.
Can you do multiple properties?
Yes. For landlords with several local properties we can align inspections and renewal dates so the annual cycle is simple to manage.
