Gas Safety Certificate (CP12) in Swansea
Arrange a Gas Safety Certificate (CP12) for your Swansea rental without the ring-around: we confirm price and availability, the certificate arrives digitally, and the renewal date is tracked for you.
Straight answer
Every rented property in Swansea with a gas supply needs an annual landlord gas safety check. Only an engineer on the Gas Safe Register can carry it out, the record lasts 12 months, and renewing in the final two months preserves your existing expiry date.

Live booking isn't switched on for Swansea yet — vetting comes before listing, in that order. Leave your details and you'll get a straight answer by email: whether we can cover the property, when, and for how much. No obligation either way.
The law
Why Gas Safety Certificate (CP12) matters for Swansea landlords
Legally, three things are required of you: a check of every appliance and flue at intervals of no more than 12 months, carried out by a Gas Safe registered engineer; a record of that check retained for at least two years; and copies to tenants — within 28 days for existing tenants, before move-in for new ones. The regulations apply UK-wide, and the HSE treats non-compliance as a criminal matter with unlimited fines available.
Landlords must have every gas appliance and flue they provide checked by a Gas Safe registered engineer at least every 12 months, keep the record for two years, give tenants a copy within 28 days of the check, and give new tenants a copy before they move in.
Equivalent annual duty applies in Northern Ireland; engineers must be Gas Safe registered.
Penalties stated are statutory maximums or court-set; Swansea Council is the local housing authority for Swansea.
Credentials
Who you're letting in
Anyone can print an invoice; only a Gas Safe registered engineer can issue a valid landlord gas safety record. That registration — and insurance to back the work — is our non-negotiable bar for professionals we book. The Gas Safe Register is publicly searchable, so you never have to take anyone's word for it, including ours.
The inspection
What the engineer actually checks
The engineer starts at the meter, checking the gas tightness of the whole installation, then works through each appliance: the boiler, any gas fire or hob you supply, and the flues that serve them. Operating pressure, combustion performance, ventilation and flame supervision are all tested; the flue check confirms combustion products actually leave the building. Anything unsafe is classified on the spot, and the visit ends with the record itself — every appliance listed, every result written down.
Pricing
What a CP12 costs
CP12 pricing is driven by time on site: how many appliances there are, how accessible they are, and whether you combine the check with a boiler service while the engineer is there. Distance and short-notice bookings can add to it. Treat the range shown as guidance for budgeting; the actual price is confirmed up front, not after the visit.
Paperwork
Copies, retention and the renewal window
Once the record is issued, three dates matter. Tenant copies: within 28 days for current tenants, before occupation for new ones — and for lets shorter than 28 days, a displayed copy in the property is acceptable. Retention: keep each record at least two years, though holding the full chain is smarter. Renewal: book in the final two months and the MOT-style rule keeps your original expiry date, so early booking never costs you certificate time.
For landlords in Swansea
Letting in Swansea: the practical points
Letting in Swansea doesn't change the gas safety requirements — the same UK-wide regulations apply from the first tenancy onward. Where geography does matter is licensing and enforcement: Swansea Council administers local housing standards and HMO licensing, and a current gas record is standard evidence whenever the council is involved with a rental.
FAQ
Before you book: quick answers
Do tenants' own gas appliances need to be on my record?
Appliances owned by the tenant are not the landlord's responsibility to check, but the pipework serving them is, and any flue serving a tenant appliance that you own must be included. Note the division of responsibility in your tenancy agreement.
Is a gas safety check the same as a boiler service?
No. The safety check confirms appliances are safe to use; a service is a maintenance clean and inspection of the boiler itself. Many landlords in Swansea book both together because the engineer is already on site, but only the safety check is a legal requirement.
My Swansea property has no gas supply — do I still need a CP12?
No. If the property has no gas supply or gas appliances, the gas safety regulations do not apply. If the supply is merely capped but a live meter remains, taking professional advice is sensible before assuming you are exempt.
How long does a gas safety check take?
Typically around 30 to 60 minutes for a property with a boiler and one or two additional gas appliances. More appliances, or access issues, extend the visit.
How long must I keep gas safety records?
Keep each record for at least two years. Because defects and history can matter in disputes, many landlords keep the full chain of records for the life of the tenancy — digital copies are fine.
What is a CP12 gas safety certificate?
CP12 is the industry nickname for the Landlord Gas Safety Record — the document a Gas Safe registered engineer issues after checking each gas appliance, flue and pipework in a rental property. Landlords letting property in Swansea must have this check done every 12 months.
