Straight answer

If you let a property with gas appliances in Dover, the law requires a gas safety check every 12 months, carried out by a Gas Safe registered engineer. The record it produces — the CP12 — goes to your current tenants within 28 days, and to new tenants before they move in.

The inspection

What the engineer actually checks

A CP12 visit is systematic rather than long: a tightness test on the supply, then every landlord-owned gas appliance tested in turn. The engineer checks that each burns correctly, that safety cut-offs work, that the room has the ventilation the appliance needs, and that flues carry fumes clear of the property. Results, defects and any action taken go on the record, alongside the engineer's Gas Safe registration number — the detail worth verifying.

Pricing

What a CP12 costs

Guidance range
£45–£90
per visit. Guidance only — not a quote. Final price confirmed before any booking.
Time on site
Around 30–60 minutes for a typical property, longer with multiple appliances.
Renewal
Every 12 months
Since 2018 you can have the check done in the two months before the due date and keep the original expiry date — an MOT-style renewal window that stops the anniversary creeping earlier each year.

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.

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, Dover 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 Dover District Council to require the current record as a licence condition too.

England, Scotland and Wales
Gas Safety (Installation and Use) Regulations 1998, regulation 36
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.
Northern Ireland
Gas Safety (Installation and Use) Regulations (Northern Ireland) 2004
Equivalent annual duty applies in Northern Ireland; engineers must be Gas Safe registered.

Penalties stated are statutory maximums or court-set; Dover District Council is the local housing authority for Dover.

Credentials

Who you're letting in

Gas work is one of the few trades where the register isn't optional: an engineer who isn't Gas Safe registered can't legally sign your record, full stop. We check registration and insurance before confirming any booking, and you can verify any engineer yourself on the public Gas Safe Register — ask to see the ID card, and check the back for the work categories it covers.

Renting out in Dover

Letting in Dover: the practical points

The gas rules themselves are national, so nothing about the check is different in Dover — what's local is the housing enforcement around it. Dover District Council 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.

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 Dover book both together because the engineer is already on site, but only the safety check is a legal requirement.

What if an appliance fails the gas safety check?

The engineer records the defect and classifies how dangerous it is. Immediately dangerous appliances may be disconnected with your permission. You must have faults fixed by a Gas Safe engineer before the appliance is used again; the record itself lists the defects found.

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.

Do the same gas rules apply in Scotland, Wales and Northern Ireland?

Yes — the Gas Safety (Installation and Use) Regulations 1998 apply UK-wide (Northern Ireland has parallel regulations to the same effect). The annual check, the 28-day tenant copy rule and Gas Safe registration requirements are consistent across all four nations.
