The legal duty stays with the landlord under the Gas Safety (Installation and Use) Regulations 1998, unless the management contract clearly makes the agent responsible, in which case HSE says the same duties apply to the agent. In practice, a full-management agent books the annual checks, tracks renewal dates, delivers tenant copies and keeps the records.

When a letting agent takes on full management, gas safety is one of the first things a landlord assumes is “handled”. Usually it is. But the law is fussier than the marketing, and if a record lapses on a managed property, both sides find out very quickly what the contract actually says. Here's who holds the duty, what a managing agent should actually be doing, and the routine that keeps a whole portfolio clean.
The landlord, by default. The duties in the Gas Safety (Installation and Use) Regulations 1998, the annual check, ongoing maintenance, tenant copies and record keeping, sit with the landlord, and instructing an agent does not make them disappear. HSE's guidance is precise about the exception: the management contract should clearly specify who is responsible for maintenance and safety check duties, and where the agent takes that responsibility on, the same duties that apply to a landlord apply to the agent. So the answer lives in the contract. If it is silent or woolly, the landlord still carries the legal duty, and the agent carries a professional mess when something slips.
Ambiguity is where lapses live, so pin the specifics down in the management agreement rather than trusting the phrase “fully managed” to mean the same thing to both of you.
HSE also suggests landlords ask to see copies of the maintenance information and safety checks from the agency, rather than assuming the work happened. A good agent will offer this before being asked.
List each managed property with gas and its next-due date, not its last-check date. Anything due within 90 days goes on this quarter's action list, and anything already lapsed goes straight to the top.
The check can be done up to two months early, from 10 months after the last one, without moving the anniversary. That window is what lets you group nearby properties into fewer engineer visits.
The properties that slip are the ones where getting in is hard. Start those first, in writing, with specific dates offered, and keep every attempt on file.
Tenant copy within 28 days, landlord copy sent, agency copy stored where it can be produced in seconds, and kept for at least two years.
One number per property is what matters: the next-due date. A spreadsheet holds that fine for a dozen properties. Past that, dates drift, because a column does not chase anyone and nobody notices the property that was added without one. This is the problem Manifold is built for: it tracks every property's renewal automatically, and the landlord and agent portal gives both sides the same self-serve view of certificates and what's due next, so the “can you resend that record” calls stop. If you manage properties for landlords, that shared view is also a straightforward thing to sell as part of the service.
Formal enforcement follows the legal duty, which usually means it lands on the landlord first. That is little comfort to the agent. An agency contracted to arrange the checks that let one lapse has a contractual problem, a complaint on the way, and quite possibly a lost landlord. The stakes rose in 2026 too: under the Renters' Rights Act, civil penalties for breaches now run up to £7,000 for a first offence and up to £40,000 for serious or repeated ones. There is no grace period after a record expires, so if one has lapsed, book the check now and tighten the routine that let it happen.
Whoever arranges it, the check itself can only be carried out by a Gas Safe registered engineer, who is the only person able to issue a valid record. This is general guidance on how the duty works, not legal advice on a specific management agreement.
