Why Gas Safety Certificates Matter

What a Gas Safety Certificate Covers and What the Record Tells You

A Gas Safety Certificate records the gas appliances and flues checked during the visit. It also shows the inspection date, the engineer’s details and any fault or follow-up action identified at the premises.

Urgent gas concern A Gas Safety Certificate appointment is not suitable for a suspected gas leak.

If you smell gas, leave the property if necessary and contact the National Gas Emergency Service on 0800 111 999 first. Once the immediate risk has been made safe, call us on 020 3892 8545 to arrange any follow-up work or gas leak detection.

The completed record What a Gas Safety Certificate Shows

The certificate provides a written record of the inspection. It identifies the items checked and records the result for the property.

Appliances and flues

The record lists the gas appliances and flues included in the booked inspection.

Inspection details

It includes the inspection date and the details of the engineer who completed the check.

Faults and actions

Any safety concern, classification or recommended action is shown on the record.

The safety inspection Some Gas Safety Problems Are Not Obvious

An appliance can appear to work normally while combustion, ventilation or flue conditions still need attention.

Combustion

The engineer checks for signs that combustion is not taking place as expected.

Ventilation

Appliances that rely on permanent ventilation need suitable airflow to operate safely.

Flues and extraction

Flues and relevant extraction arrangements must allow combustion products to leave the premises correctly.

Rental properties Landlords Need a Current Gas Safety Record

Landlords must arrange an annual gas safety check for the appliances and flues they own and provide for tenants.

Annual check

The relevant landlord-owned appliances and flues must be checked every twelve months.

Tenant copies

Existing tenants receive a copy within 28 days. New tenants receive the current record before moving in.

Records retained

The landlord must keep each Gas Safety Record for at least two years.

Commercial premises The Inspection Scope Depends on the Equipment

Commercial gas safety inspections are based on the appliances, installation and operating arrangements at the premises.

Gas appliances

The agreed inspection may cover the gas-fired equipment listed before the visit.

Ventilation and extraction

Relevant ventilation and extraction arrangements are considered as part of the inspection scope.

Isolation and controls

Accessible isolation, pipework and control arrangements are checked where they form part of the booked work.

Work outside the certificate Repairs and Servicing Are Booked Separately

The certificate records the inspection result. It does not automatically include repairs, servicing, replacement parts or installation work.

Repair work

A defect may need a separate appointment before the appliance can return to normal use.

Replacement equipment

New or replacement appliances are arranged as a separate installation service.

Routine servicing

Servicing covers maintenance work outside the scope of the Gas Safety Certificate.

Why Choose Citywide Plumbers

Gas Leak Investigation Focused on the Fault and the Affected Installation

Gas leak detection is used to investigate a suspected loss of gas once any immediate emergency has been dealt with. We review what you have noticed, test the relevant part of the installation and explain what can be confirmed from the areas that are accessible during the visit.

Investigation Based on What You Have Noticed

Tell us where and when the concern was noticed, which appliances were in use and whether any recent installation or building work has taken place. This helps the engineer focus the initial checks.

Findings and Next Steps Explained Clearly

We explain the likely source and what needs to happen next. A hidden leak may require further isolation, access or investigation before repair work and making good can be arranged.

Gas Safety Certificate Questions Answered Clearly

Practical answers about Gas Safety Certificates, inspections, prices, landlord records and what happens after the engineer completes the check.

01 What is a Gas Safety Certificate?

A Gas Safety Certificate, also called a Gas Safety Record, lists the gas appliances and flues checked during the visit. It also records the inspection date, the engineer’s details and any safety issue found.

02 Who needs a Gas Safety Certificate?

Landlords need a current Gas Safety Record for the gas appliances and flues they provide for tenants. Commercial premises may need a record suited to the equipment and how the property is used.

03 How much does a Gas Safety Certificate cost?

A CP12 costs £87 for one domestic gas appliance, £97 for two and £105 for three. The £33 gas meter and soundness check is a separate option and is not a full Gas Safety Certificate. CP42 pricing depends on the commercial kitchen scope.

04 What does the gas safety check include?

The engineer checks the appliances and flues included in the booking. The exact work depends on the appliance type, fuel, ventilation, flue arrangement and the type of premises.

05 Who can issue a Gas Safety Certificate?

The inspection must be completed by a Gas Safe registered engineer who is qualified for the appliance and work involved. Citywide Plumbers is registered under number 669196. Check our registration and listed competencies.

06 What happens after the inspection?

The engineer completes the relevant Gas Safety Record and explains the result. The document shows what was checked and notes any defect or action required.

07 What happens if a fault is found?

The record will show the fault and the action taken or advised. An appliance classified as unsafe must not be used until the problem has been dealt with. Repairs and replacement parts are arranged separately.

08 Is a Gas Safety Certificate the same as a boiler service?

No. A Gas Safety Certificate records the safety check for the appliances and flues included in the visit. A boiler service is a separate maintenance appointment and may include cleaning, adjustment or further work.

09 How often does a landlord need a Gas Safety Certificate?

Landlords must arrange a gas safety check every twelve months for the gas appliances and flues they own and provide for tenants to use.

10 When should tenants receive the Gas Safety Record?

Existing tenants must receive a copy within 28 days of the completed check. New tenants must receive the current record before moving into the property.

CP12 is the familiar name for the Landlord Gas Safety Record used for residential rental properties. View the CP12 Landlord Gas Safety Record service.

12 What is a CP42 Gas Safety Certificate?

CP42 is commonly used for a commercial catering gas safety record. It applies to commercial kitchens using gas-fired catering equipment. View the CP42 commercial catering gas safety service.

13 How should I prepare for the appointment?

Make sure the engineer can reach the gas meter, each booked appliance and any relevant flue, ventilation or extraction points. Provide the appliance count and access details when booking.

14 What should I do if I smell gas?

Leave the property if necessary and call the National Gas Emergency Service on 0800 111 999. Do not wait for a certificate appointment. Once the immediate risk has been made safe, call Citywide Plumbers on 020 3892 8545 if follow-up work is required.
