Gas Safety Certificate (CP12) in Portsmouth
One short form, and your Gas Safety Certificate (CP12) in Portsmouth is in hand — correctly registered professionals, honest pricing guidance, and your certificate stored with its renewal date.
Straight answer
Every rented property in Portsmouth 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.

Pricing
What a CP12 costs
What moves the price is mostly appliance count: a flat with a single combi boiler sits at the bottom of the range, while a house with a boiler, hob and gas fire takes longer and costs more. Adding a boiler service to the same visit is usually cheaper than a separate appointment. The figures above are national guidance — your confirmed price comes before anything is booked.
For landlords in Portsmouth
Letting in Portsmouth: the practical points
For landlords in Portsmouth, the practical points are the universal ones: annual check, Gas Safe engineer, tenant copies on time. Keep the record where you can produce it quickly — for your agent, your insurer, or Portsmouth City Council if the property is licensed or ever inspected. Certificates that can't be found cause almost as much trouble as certificates that were never done.
The law
Your legal duty, in plain English
The Gas Safety (Installation and Use) Regulations 1998 make the annual check a hard legal duty wherever in the UK you let, Portsmouth included. The HSE prosecutes failures — penalties are unlimited fines and potentially imprisonment — and in England an expired record blocks a valid Section 21 notice. If the property is a licensed HMO, expect Portsmouth City Council to require the current record as a licence condition too.
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; Portsmouth City Council is the local housing authority for Portsmouth.
The inspection
What the engineer actually checks
Expect the visit to run appliance by appliance. Tightness testing at the meter comes first, ruling out leaks anywhere in the pipework. Each appliance is then fired up and tested — burner pressure or heat input, safety devices, stability, ventilation to the room — and each flue is checked for pull and termination. Defects are graded by how dangerous they are, and only a Gas Safe registered engineer's signature makes the resulting record valid.
Paperwork
Copies, retention and the renewal window
The paperwork rules are as enforceable as the check itself. Give existing tenants their copy within 28 days and new tenants theirs before they move in; keep every record for a minimum of two years; and diarise renewal for the two-month window before expiry — done then, the new record runs from the old expiry date rather than resetting the clock early.
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.
FAQ
Common questions about the Landlord Gas Safety Record (commonly called a CP12)
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.
My Portsmouth 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.
Who can carry out a gas safety check in Portsmouth?
Only an engineer on the Gas Safe Register may legally carry out landlord gas safety checks anywhere in the UK, including Portsmouth. Always ask to see the engineer's Gas Safe ID card — you can verify it on the official register.
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.
Are the gas rules different for an HMO in Portsmouth?
The annual check itself is the same, but HMO licensing (administered by Portsmouth City Council) usually requires you to provide the current gas safety record with your licence application and on request. Check your licence conditions for any extra record-keeping duties.
What happens if I let a property in Portsmouth without a valid gas safety record?
It is a criminal offence under the Gas Safety (Installation and Use) Regulations 1998. Cases are prosecuted by the HSE and can lead to unlimited fines and, in serious cases, imprisonment. A missing record can also block a valid Section 21 notice in England.
