Expired Gas Safety Certificate: Fines and What Happens Next

A landlord gas safety record has lapsed. What actually happens?

The honest answer is that most of what circulates online about this is wrong — including a specific fine figure that has not been the law since 2015, a claimed grace period that is a synchronisation mechanism dressed up as an amnesty, and a possession consequence that ceased to exist on 1 May 2026. This page sets out the position from the regulations themselves.

Disclaimer: This guide is for information only and does not constitute legal advice. It describes the position in England as at 19 August 2026. Always consult a solicitor or a competent gas safety professional for your specific situation.

What Regulation 36 Actually Requires

The duty sits in regulation 36 of the Gas Safety (Installation and Use) Regulations 1998. It has three limbs that landlords tend to run together.

Maintenance. Regulation 36(2) requires the landlord to keep the relevant gas fittings and flues in a safe condition. That is a continuing duty, separate from the annual check.

The annual check. Regulation 36(3)(a) and (b) require each appliance and flue to be checked for safety "within 12 months of being installed and at intervals of not more than 12 months since it was last checked for safety", and — where a new lease is granted — "checked for safety within a period of 12 months before the lease commences".

Giving the record to the tenant. Regulation 36(6) requires a copy to be given to each existing tenant within 28 days of the date of the check, and to any new tenant before that tenant occupies the premises. Where occupancy is 28 days or less, the record may instead be displayed prominently.

Two details that get repeated incorrectly. There is no regulation 36(6A) — regulation 36 runs from (1) to (12), and any article citing 36(6A) is quoting something that does not exist. And regulation 36(10) provides that nothing done or agreed by the tenant counts towards the landlord discharging the duty, except in relation to access.

Record Retention Is Not a Flat Two Years

Regulation 36(3)(c) is more precise than the usual summary. The record must be retained:

"until there have been two further checks of the appliance or flue under this paragraph or, in respect of an appliance or flue that is removed from the premises, for a period of 2 years from the date of the last check"

So for an appliance that stays in the property, retention runs until two further checks have happened — roughly two years, but defined by events, not by the calendar. The flat "two years" you will see quoted, including in some official summaries, is a simplification. Keep the last three records and you are safe. Our page on how long a gas safety certificate is valid covers the twelve-month cycle in detail.

Who Enforces It, and What the Penalties Are

The enforcing authority is the Health and Safety Executive, not the local council. That is set by regulation 3(1) of the Health and Safety (Enforcing Authority) Regulations 1998. Landlords who expect a council officer are looking in the wrong direction.

Breach of regulation 36 is an offence under section 33(1)(c) of the Health and Safety at Work etc. Act 1974. A word of caution on sources here: you will see articles cite section 33(1A). That subsection was repealed in 2009 and replaced by sections 33(2) and (3) by the Health and Safety (Offences) Act 2008. Anything relying on it is at least seventeen years out of date.

The penalties are in Schedule 3A:

The "£20,000 maximum fine" is not the law. That figure was replaced with the single word "fine" — meaning an unlimited fine — on 12 March 2015 by the Legal Aid, Sentencing and Punishment of Offenders Act 2012 (Fines on Summary Conviction) Regulations. Any page still quoting £20,000 has not been checked in eleven years.

Imprisonment is genuinely available, on both routes. It is not a theoretical maximum reserved for corporate defendants.

How the Fine Is Actually Calculated

Courts sentence health and safety offences under the Sentencing Council's definitive guideline, which has applied since 1 February 2016 and expressly covers section 33(1)(c) offences. The structure is:

1. Culpability — from very high (deliberate breach) down to low
2. Harm — assessed by the seriousness of the harm risked and the likelihood of it occurring, not only by what actually happened
3. Turnover — organisations are placed in bands, with micro being turnover of £2 million or less and small being £2 million to £10 million

Culpability and harm produce a starting point and a range; turnover determines which table applies. For individuals, the guideline works through fine bands A to F and provides for custody up to the statutory maximum of two years.

The point that matters for a landlord reading this: the guideline is driven by harm risked, not harm caused. A property where nobody was hurt but where an unchecked appliance created a real risk of carbon monoxide exposure is not automatically at the bottom of the range. If you are facing enforcement, take advice and work from the definitive guideline itself rather than from a summary.

Three Things That Do Not Happen

Being clear about what an expired certificate does not trigger is as useful as knowing what it does, because each of these is widely asserted.

It does not block possession

This was true, and it is no longer true. The bar operated through section 21 and the associated 2015 regulations, and section 21 was abolished on 1 May 2026. Section 21A of the Housing Act 1988 was omitted on the same date. The 2015 regulations were revoked in relation to private assured tenancies, and the substantive requirements are preserved only for the narrow transitional cases where a Section 8 notice was already live before commencement.

Sections 7 and 8 of the Housing Act 1988, which now govern possession, contain no compliance precondition of any kind for gas.

There is one thing to watch on the horizon. Section 90 of the Renters' Rights Act inserts a new section 7(5ZC) creating a possession bar tied to registration on the Private Rented Sector Database — not to gas. That provision is listed as "yet to be inserted" and is not in force as at 19 August 2026. When it commences, database registration becomes a genuine precondition. Our complete picture of the Section 8 grounds tracks the current position.

On Trecarrell House Ltd v Rouncefield [2020] EWCA Civ 760 — the Court of Appeal decision holding that late delivery of a gas safety record did not permanently bar a section 21 notice — the correct description is that it is moot for new private assured tenancies, not that it is no longer good law. It continues to matter for saved and transitional cases, for tenancies outside the private assured category, and in Wales.

There is no rent repayment order for a gas breach

Rent repayment orders are available only for the offences listed in the table at section 40(3) of the Housing and Planning Act 2016. That list covers unlawful eviction and harassment, the new Housing Act 1988 section 16J offences on re-letting after Ground 1 or 1A, failure to comply with an improvement or prohibition order, unlicensed HMOs and unlicensed houses, and breach of a banning order.

No Health and Safety at Work Act offence appears in it. A gas safety breach is not, by itself, an RRO offence.

There is a real indirect route, though, and it is worth understanding. If the condition of the property generates a hazard under the housing health and safety rating system, the council can serve an improvement notice under Part 1 of the Housing Act 2004 — and failure to comply with an improvement notice (section 30(1)) is on the RRO list. The gas problem does not produce the RRO. The unremedied hazard and the ignored notice do.

There is no local-authority civil penalty for gas

Civil penalties under section 249A of the Housing Act 2004 are available only for a "relevant housing offence" as defined in section 249A(2), and that definition does not include Health and Safety at Work Act offences.

Two figures worth keeping straight while we are here, because they are routinely attached to the wrong thing:

• The section 249A(4) maximum civil penalty rose to £40,000 on 1 May 2026 (it was £30,000). It applies to relevant housing offences — not gas.
• The £7,000 figure that appears in a lot of 2026 content is the penalty under section 16I(6) of the Housing Act 1988 for breaches of the sections 16D and 16E restrictions after Ground 1 or 1A possession. It has nothing to do with gas safety either.

Our complete guide to landlord fines and penalties sets out which penalty attaches to which obligation.

The "Grace Period" That Is Not a Grace Period

This is the single most consequential misunderstanding in this area, because landlords rely on it.

The two-month rule is regulation 36A, inserted in 2018. It is not an HSE concession and it is not discretionary. It has two limbs, and they do completely different things.

Regulation 36A(1) — the early check. A check completed within the two months before the deadline is treated as having been made on the deadline date. This is the useful, everyday provision: you can get the engineer in early without shortening your next cycle. Our page on the gas safety certificate grace period explains how the anniversary works.

Regulation 36A(2) and (3) — the late check, heavily restricted. A check up to two months after the deadline is permitted, but only:

• Once per appliance, ever, and
• Only to bring that appliance's deadline into line with another appliance's deadline in the same premises

It is an alignment tool for a property with, say, a boiler and a gas fire on different cycles. A property with a single gas appliance cannot use it at all. There is no general two-month amnesty for a late check, and treating it as one is exactly the assumption that turns an administrative slip into an offence.

If your record has already lapsed: book the check immediately, and do not stop letting the tenant know. See our page on a backdated gas safety certificate for what an engineer can and cannot do about the dates.

If the Tenant Refuses Access

HSE's guidance is to leave a notice, write to the tenant explaining that the check is a legal requirement and a safety measure, repeat the attempt, and keep records of everything you did.

What HSE does not say is that this is a defence. Its own formulation is that "it would ultimately be for a court to decide if the action taken was reasonable". Treat the record of your attempts as evidence that may help, not as a shield. And note regulation 36(10): the tenant's conduct discharges nothing except in relation to access.

The practical implication is a paperwork one. Contemporaneous, dated records of every access attempt — the letter, the date, the engineer's abortive visit, the response or lack of one — are the only version of this that is worth anything. Our guide on documenting property condition for court covers the same discipline in a different context.

Frequently Asked Questions

What is the fine for an expired gas safety certificate?

There is no fixed fine. Breach of regulation 36 is an offence under section 33(1)(c) of the Health and Safety at Work etc. Act 1974, and the penalties are set by Schedule 3A. On summary conviction in England and Wales the fine is unlimited — the former £20,000 cap was replaced with the word "fine" on 12 March 2015 — and imprisonment up to the general limit in a magistrates' court is available. On conviction on indictment the fine is unlimited and imprisonment can be up to two years. Courts apply the Sentencing Council's health and safety guideline, which scales the fine to culpability, harm risked and the offender's turnover.

Does an expired gas safety certificate stop me getting possession?

No, not for a private assured tenancy. The link between gas safety compliance and possession ran through section 21, and section 21 was abolished on 1 May 2026. Sections 7 and 8 of the Housing Act 1988, which govern possession now, contain no gas safety precondition. The 2015 regulations that carried the requirement were revoked in relation to private assured tenancies, though they are preserved for certain transitional cases where a Section 8 notice was already live. Compliance still matters for every other reason.

Is there a two-month grace period for a gas safety check?

Not in the way it is usually described. Regulation 36A(1) lets you carry out the check up to two months before the deadline without losing your place in the cycle — the check is treated as made on the deadline date. Regulation 36A(2) and (3) do allow a check up to two months after the deadline, but only once per appliance and only to bring that appliance's deadline into line with another appliance in the same premises. It is a synchronisation tool, not an amnesty, and it is unavailable to a property with a single boiler.

A note on checking this yourself: legislation.gov.uk shows its "up to date" status banner on Acts, but not on statutory instruments. When you read regulation 36 online, there is no banner telling you whether amendments are incorporated — which is precisely why so much secondary commentary on gas safety is stale. Check the amendment history in the "Changes to legislation" panel.

The Underlying Problem

Nearly every expired certificate is an administrative failure rather than a decision. The deadline was twelve months away, then it was not, and nothing in the ordinary running of a tenancy prompted anyone to look.

LetSorted stores gas safety records against the property and alerts before the deadline, alongside EICR and EPC expiry and deposit protection deadlines. When a record does exist, it is where you need it — attached to the property, retrievable, and ready to hand to a new tenant before they occupy.

Get your compliance dates tracked rather than remembered.
