Gas Safety Certificate Cost for Landlords: What You Should Pay

Prices and rules last reviewed: 21 October 2026.

How much does a landlord gas safety certificate cost?

When we checked on 21 October 2026, four online providers and two local directories had these prices published. These are listed or 'from' prices, not quotes for a specific property, so treat them as a starting point and get a fixed quote before booking.

MyLandlordCertificate's page is inconsistent about whether its £64.99 and £74.99 prices include the boiler, so we've left it out of the comparison below; check with them before relying on it.

So on 21 October 2026, three online providers listed £50–£69 for one appliance and three listed £58–£79 for two (Landlord Certificates Ltd, Landlord Certifications and Multicerts). Some of these are London or M25 providers; some London providers add their own parking or Congestion Charge fees (MyLandlordCertificate lists £10 parking and £20 Congestion Charge fees where they apply). The Manchester and Leeds directory figures don't state how many appliances they cover, so they aren't directly comparable with the per-appliance prices above.

None of these businesses has been confirmed as Gas Safe registered for this article. Before you book with anyone, check the engineer or business on the Gas Safe Register website (HSE), and ask to see the back of their Gas Safe card to confirm they're competent for the type of gas work your property needs.

What changes the price

A few things genuinely move the price:

• Number of appliances. Several providers above price per appliance, so each extra appliance (a gas fire, a freestanding cooker, a second boiler) adds to the price.
• Combining with a boiler service. Some providers (Landlord Certifications, MyLandlordCertificate) offer a combined service-and-certificate price alongside the certificate-only price.
• Area and parking. MyLandlordCertificate states it may add a parking charge or the Congestion Charge where they apply, on top of its listed price.
• Booking early or late. You can book your check up to two months before it's due without losing your original renewal date (see below) — booking in good time gives you more choice of engineer and appointment slot.

Beyond these, we didn't find a published, measured UK average for this check — the figures above are the listed prices of the providers we checked.

Is a gas safety check the same as a boiler service?

No. They're different things, done for different reasons.

The annual gas safety check is the legal safety inspection landlords must arrange: it checks appliances and flues, and ends in the gas safety record (often still called a CP12). A boiler service is separate maintenance recommended by the manufacturer. Landlords must ensure the gas fittings and flues they provide are kept in a safe condition (regulation 36), and HSE's guidance says appliances and flues should be serviced in accordance with the manufacturer's instructions, separately from the gas safety record requirement (HSE). A service doesn't replace the gas safety record.

Several providers above sell a combined "service and certificate" visit, which can be convenient since it's a single appointment with your tenant, but a service is not a substitute for the safety check, and the safety check is not a substitute for maintaining the boiler.

What the check covers (and what it doesn't)

The annual check covers each gas appliance and flue you provide at the property, and it must be done by a Gas Safe registered engineer. At the end of it, you get a record of the check.

Three things are often misunderstood:

• Pipework. Installation pipework itself isn't covered by the annual gas safety check, but you must still ensure it, and the gas fittings and flues you provide, are maintained in a safe condition — this isn't a gap in your duties, just a different route to covering it (HSE; regulation 36).
• Tenant-owned appliances. Appliances the tenant brought themselves and owns aren't covered by your duties as landlord (HSE).
• Defects don't stop a record being issued. If the engineer finds a defect, the record is still completed — it must include any safety-related defect identified and any remedial action taken (HSE).

For the detailed legal background on what the check must cover, see our full gas safety certificate guide, and our landlord compliance hub for every other certificate you need to track.

What the law requires of landlords in England, Wales and Scotland

Keeping this brief — see the full guide and penalties article for detail:

1. Annual check. You must ensure a gas safety check is done every year on each gas appliance and flue you provide (HSE).
2. Before a new lease. The checks must have been done within one year before the start of the lease date (HSE) — this is about when the last check happened, not a requirement for a fresh check at every new tenancy.
3. Who can do it. All checks must be done by a Gas Safe registered engineer (HSE).
4. Giving tenants the record. You must give existing tenants a copy of the gas safety record within 28 days of the check being completed, and give a new tenant a copy of the latest record before they move in (HSE). For a right to occupy of 28 days or less, the record may instead be prominently displayed in the property rather than handed over (regulation 36). HSE's guidance on holiday accommodation and hotels says that for occupancies of less than 28 days a copy of the record should be displayed in a prominent place (HSE).
5. Record keeping. Keep each record until two further checks of that appliance or flue have been done, or, for an appliance or flue that has been removed from the premises, for two years from the date of its last check (regulation 36); HSE's guidance says to keep records for at least two years in any case (HSE). Because early or realigned checks don't always fall exactly 12 months apart, go by the number of checks rather than the calendar alone.
6. Booking early. A check completed within the two months before your deadline date is treated as if it were done on the deadline date, so you don't lose your original renewal date by booking early (regulation 36A).

Breaching these Regulations is a criminal offence; on conviction on indictment the penalty is imprisonment for a term not exceeding two years, a fine, or both (Schedule 3A, Health and Safety at Work etc. Act 1974). For the full picture on enforcement, see what happens if you miss a deadline.

Northern Ireland

As of 21 October 2026, Northern Ireland landlords must arrange an annual safety check for all gas boilers by someone registered with the Gas Safe Register and issue the record to their tenant within 28 days of each annual check (nidirect). Under the current Regulations, each gas safety record must be kept for two years from the date of the check (regulation 36, 2004 NI Regulations), and there is currently no early-check rule equivalent to Great Britain's.

This changes from 30 November 2026: new Regulations (S.R. 2026/178) will introduce the same two-month early-check rule used in Great Britain, change record retention to "until two further checks have been done" (matching Great Britain), and limit the defects that must be recorded to safety defects. Until 30 November 2026, the current rules above apply.

Checking early without losing your renewal date

In England, Wales and Scotland, you can have the check done up to two months before your deadline date and it still counts as done on the deadline date (regulation 36A). From 30 November 2026, the same will apply in Northern Ireland (S.R. 2026/178).

This is useful for budgeting and scheduling: it means you can book the engineer in a quiet period, combine the visit with a boiler service, or get ahead of a run of certificates expiring around the same time across a portfolio. AnnualVault sends email reminders 60, 30 and 7 days before a renewal date, which fits neatly into this two-month window, giving you time to shop around rather than booking whoever is available first.

How to avoid overpaying

• Get more than one quote. The prices above show real variation even among providers covering similar areas — ask what's included (number of appliances, VAT, parking) before comparing.
• Check the engineer is Gas Safe registered before booking (HSE), and check their card for the type of work they're competent in.
• Ask what's included. A price that looks cheap may exclude VAT, cover only one appliance, or add a parking fee once you book.
• Consider combining with a service, if your boiler is due one anyway, to save a second appointment — compare the combined price with separate prices for the safety check and the service.
• Book within the two-month window rather than waiting until the deadline, so you have time to compare quotes instead of taking the first available slot.

Keeping track of your renewal date

With appliances, record-keeping duties and a two-month early-check window to juggle, it's easy to lose track of exactly when your gas safety check is due, especially across more than one property. AnnualVault lets you add your renewal date and get email reminders 60, 30 and 7 days before it's due, and lets you upload the certificate itself so it's stored next to that date. AnnualVault doesn't provide legal advice or guarantee you're compliant — that responsibility stays with you — but it helps make sure the date doesn't catch you out.
