Gas Safety Certificate (CP12) in Windsor
One short form, and your Gas Safety Certificate (CP12) in Windsor is in hand — correctly registered professionals, honest pricing guidance, and your certificate stored with its renewal date.
Straight answer
The CP12 is the annual gas safety record UK law requires for rental homes — Windsor included. A Gas Safe registered engineer inspects every gas appliance and flue, issues the record, and copies go to tenants: within 28 days for current tenants, before occupation for new ones.

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 inspection covers three layers: the supply (a tightness test from the meter), the appliances (combustion, pressure, safety devices, ventilation — tested with each appliance running), and the flues (visual condition plus confirmation that combustion gases discharge safely outside). An appliance the tenant owns isn't yours to certify, but pipework serving it is, and it stays in scope. The signed record closes the visit.
The law
Your legal duty, in plain English
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; Royal Borough of Windsor and Maidenhead is the local housing authority for Windsor.
Letting property in Windsor
Letting in Windsor: the practical points
The gas rules themselves are national, so nothing about the check is different in Windsor — what's local is the housing enforcement around it. Royal Borough of Windsor and Maidenhead is the housing authority for the area, and if your property needs an HMO licence, the current gas record is the kind of document its conditions will expect you to hold and produce on request.
Pricing
What a CP12 costs
Two identical adverts can hide very different jobs — one boiler versus four appliances, ground-floor flat versus awkward loft access. That's why we show a guidance range rather than a headline teaser price, and confirm the real figure for your property before you commit. Bundling the annual boiler service into the same visit typically works out cheaper than booking it separately.
FAQ
What Windsor landlords ask us
What does the gas safety record actually include?
It lists each appliance and flue checked, the checks performed, defects found and action taken, the engineer's name, registration number and signature, the property and landlord details, and the date of the check.
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 Windsor must have this check done every 12 months.
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.
Do I have to give tenants a copy of the gas safety record?
Yes. Existing tenants must receive a copy within 28 days of the check, and new tenants must get one before they move in. For rental periods under 28 days, displaying a copy in the property is acceptable.
Are the gas rules different for an HMO in Windsor?
The annual check itself is the same, but HMO licensing (administered by Royal Borough of Windsor and Maidenhead) 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.
