An unsafe gas appliance in a rented home: what the landlord should do next

When a Gas Safe registered engineer declares an appliance in an occupied rental unsafe, the annual check is not the end of the story. Protect the resident, keep the appliance out of use, arrange competent repair before it returns to service, provide reasonable interim heat or hot water, and keep the records.

What has happened

During an annual gas safety check, a callout or a repair, a Gas Safe registered engineer identifies a fault and classifies the appliance under the gas industry's unsafe situations procedure, typically as "Immediately Dangerous" or "At Risk". With the user's permission the engineer turns off and labels an Immediately Dangerous appliance. The landlord's duties under the Gas Safety (Installation and Use) Regulations 1998 include maintaining gas appliances and flues in a safe condition, arranging an annual safety check by a Gas Safe registered engineer, and keeping the records; an unsafe finding turns those standing duties into an active repair case.

Immediate actions

Confirm the resident is safe now. If there is any suggestion of a gas escape or carbon monoxide, the engineer or resident should call the national gas emergency service and the property should be ventilated and evacuated if anyone feels unwell. Accept the engineer's isolation of the appliance and make sure the warning label stays in place. Arrange a competent repair or replacement with a Gas Safe registered engineer as a priority, and where the unsafe appliance provided heating or hot water, organise reasonable temporary provision for the resident. Tell the resident plainly what is unsafe, what not to use, and what happens next.

What not to do

Do not reconnect or use a condemned appliance, remove a warning label, or ask the tenant to "just avoid using it too much". Do not use an unregistered person to carry out gas work. Do not leave a resident without heating or hot water over a cold period without arranging a temporary solution. And do not treat the signed gas safety record as evidence of safety once an appliance has been found unsafe; the record must reflect the actual current state.

Who is responsible

The landlord is the dutyholder for the annual check, maintenance and record-keeping and for arranging the repair; a managing agent may act under the management agreement. Only a Gas Safe registered engineer may work on the appliance and decide when it is safe to return to use. The resident should not use a labelled appliance and should allow access for the repair.

Evidence and records

Keep the engineer's report and the classification (ID/AR), the warning-label details, the isolation date, the repair or replacement work and its completion, and the new gas safety record confirming the appliance is safe to use again. Record any interim heating provided and communications with the resident. Note whether a dangerous gas fitting was reported by the engineer, as certain dangerous gas fittings are reportable under RIDDOR by the registered engineer, and keep evidence of any RIDDOR involvement.

Escalation

Escalate a suspected gas escape or CO exposure to the national gas emergency service immediately. Escalate access problems for the repair through your access process, since a home reliant on a condemned heating appliance cannot simply wait. Where the appliance cannot be economically repaired, escalate to replacement. If a carbon monoxide alarm is involved, coordinate with the smoke and CO alarm fault response, and if the annual check itself is being refused, see gas safety check: no access.

Prevention

Keep gas safety on a planned cycle with reminders well before the annual check falls due, use the same competent contractor so appliance history is known, replace ageing appliances before they fail, and track any recurring faults that suggest a deeper problem. A record that shows the appliance history, check dates and past faults makes an unsafe finding faster to resolve and easier to evidence.

Where Complys can help

Complys can hold each property's gas safety records, appliance inventory, check dates and repair history, flag the annual check before it is due, and keep the isolation-to-repair trail together with the new safety record. It does not carry out gas work or judge whether an appliance is safe; those decisions belong to the Gas Safe registered engineer. Ask the Complys team to demonstrate the gas-record and reminder workflow against a real unsafe-appliance case.
