Gas safety certificate in London
Ask us to arrange a gas safety check for your property. A registered subcontractor carries out the check and issues any resulting paperwork in their own company name under their registration. We confirm scope and quote first; a certificate depends on the inspection outcome.
Identify the property and appliances to be checked
Tell us whether the enquiry is for a let property and list the gas appliances and any flues you know about, rather than assuming that a boiler alone defines the scope. Include the property postcode, type of dwelling and any access arrangements with a tenant or agent. SJW arranges the enquiry; a registered subcontractor carries out the gas safety check under their own registration and company name.
If you have a previous gas safety record, send its date and appliance list so the requested inspection can be scoped accurately. A past record does not determine the result of a new visit. The registered subcontractor must inspect the relevant installation and decides what paperwork can be issued from the actual findings. We will confirm availability and a quote before arranging attendance.
Arrange access without assuming a pass
The person attending needs safe access to the appliances, meters and relevant areas of the property. Let us know if keys, building entry, a tenant appointment or restricted plant access must be coordinated. Do not arrange for anyone to remove a boiler casing or work on gas fittings ahead of the check. SJW can help coordinate the visit; the registered subcontractor conducts the gas inspection under their own registration.
A gas safety check is an assessment, not a purchase of a guaranteed passing certificate. If the registered subcontractor finds a concern, follow their safety advice and ask what action is needed before the matter can be resolved. Any remedial gas work and later sign-off require an agreed scope and are carried out by registered subcontractors in their own company name; the first check does not imply a free or automatic retest.
Paperwork and landlord records
Explain whether you need a landlord gas safety record, another type of report, or advice on what applies to your property. The registered subcontractor who carries out the gas check issues any resulting gas paperwork under their own registration and company name, not as an SJW-issued record. Confirm the requested document and its recipients when agreeing the quote; paperwork depends on the inspection outcome.
Keep the resulting record with the property's previous gas safety information and make sure the correct people receive it under the applicable landlord rules. If appliances or access arrangements have changed since the last check, raise that before the appointment. SJW can review the subcontractor's findings with you and discuss a separate quote for further work, but cannot promise a particular issue date or a satisfactory result in advance.
Agree the scope and price first
There is no fixed CP12 price or direct gas-check booking on this page. The number and type of appliances, site access and requested document matter to the quote. Send those details and any previous record through the enquiry route; we will check registered subcontractor cover, confirm the proposed scope and quote, then discuss a suitable appointment if the work can be arranged.
A boiler service, appliance repair and gas safety check are not interchangeable line items. If you need more than one, list each request explicitly so the quote states what is included and what is separate. A registered subcontractor carries out and signs off the gas work under their own registration and company name, and any additional work follows its findings rather than being presumed included in a certificate enquiry.

Frequently asked questions
Who needs a CP12?
Landlords must have a gas safety check every 12 months and give tenants a copy of the certificate within 28 days.
Can I request a CP12 check?
Yes. Send the property and appliance details. We will confirm scope, subcontractor cover and a quote before agreeing a visit.
Can I ask for more than one appliance to be checked?
Yes. List the appliances and any known flues in the enquiry. We will confirm the proposed scope and quote before arranging a registered subcontractor to carry out the gas check under their own registration.
What should I arrange with my tenant?
Tell us who controls access and whether a tenant or agent needs to meet the registered subcontractor. The appliance and meter locations also help us scope the visit; we confirm an appointment only after cover and the quote are agreed.
Does paying for a check guarantee a certificate?
No. The registered subcontractor's inspection findings determine what resulting paperwork can be issued under their own registration and company name. Any concerns or remedial work are discussed separately.
Will the gas safety record be in SJW's name?
No. The registered subcontractor carrying out the check issues any resulting gas paperwork under their own registration and company name. We can confirm the intended recipient when scoping the enquiry.
Can a boiler service be done at the same visit?
Tell us you need both before accepting a quote. Servicing and a landlord gas safety check have different scopes; we will check whether a registered subcontractor can arrange them together and quote accordingly, without assuming either is included in the other.
