Gas Safety Certificate (CP12) in Exeter

Landlords in Exeter have the same legal duty as landlords anywhere else in Great Britain. The Gas Safety (Installation and Use) Regulations 1998 require an annual gas safety check on every gas appliance, flue, and associated pipework owned or supplied by the landlord. That check must be done within 12 months of the previous certificate, and only a Gas Safe registered engineer can carry it out and issue the CP12. Miss the deadline, and the property is out of compliance from that point on.

The penalties are serious for a reason. A landlord who fails to keep gas safety records up to date can face a fine of up to £6,000 and/or 6 months imprisonment. In Exeter’s local market, the risk matters because there were 7,100 property sales in the Exeter postcode area in the last 12 months, with 209 new build sales and a 15.9% drop in transaction numbers across the same period. A mixed rental portfolio often means a landlord is managing older terraces, newer flats, and detached homes at the same time, so the annual inspection date can slip unless it is booked in advance.

Records matter just as much as the inspection. Landlords must give a copy of the gas safety certificate to existing tenants within 28 days of the check, and new tenants must receive it before they move in. If the property has more than one gas appliance, every item must be listed clearly on the certificate. Our team keeps the paperwork straightforward, so landlords can prove compliance without chasing missing notes or unreadable test results.

Carbon monoxide is often called the silent killer because you cannot see it, smell it, or taste it. A poorly maintained boiler, blocked flue, broken burner, or lack of ventilation can all produce dangerous levels of CO without much warning. Since October 2022, CO alarms have been mandatory in rented properties, and landlords in Exeter should treat that as part of the wider gas safety picture. Our engineers check for signs that an appliance could be producing carbon monoxide before the issue becomes an emergency.

The symptoms can start mildly and still be serious. Headaches, dizziness, nausea, confusion, and tiredness are common warning signs, and they can be mistaken for a minor illness. That is why we inspect the flame picture, burner condition, flue performance, ventilation, and signs of spillage during a gas safety visit. In a property market where the Exeter postcode area recorded an average sold price of £336,000 between April 2025 and March 2026, losing safe operation is a risk no landlord should leave unaddressed.

Exeter’s sales mix shows why CO checks matter across different property types. Terraced homes accounted for 31.7% of sales in the last 12 months, semi-detached homes 21.5%, detached homes 33.9%, and flats 12.9%. Each type can hide a different gas appliance layout, and older installations do not always behave like newer ones. A fitted alarm helps, but it never replaces a proper inspection from a Gas Safe engineer.

Gas safety certificate prices in Exeter start from £60, and the cost usually reflects the number of gas appliances rather than the value of the property. A simple flat with one boiler can be quicker than a terrace with a boiler, cooker, and gas fire, so the final quote changes with the job size. That matters in Exeter because the local market includes 7,100 sales in the last 12 months, a 15.9% drop in transactions, and a mix of detached, semi-detached, terraced, and flat homes. Our pricing stays tied to the inspection itself.

The certificate is normally issued soon after the visit if the property passes. We send the completed CP12 to the landlord, who must keep a copy and pass one to the tenant within 28 days, or before move-in for a new tenancy. If the inspection finds a fault, the price of the initial check still applies, then any repair and re-check are arranged separately. With Exeter asking prices at £378,790 in May 2026 and the average postcode-area sold price at £336,000 between April 2025 and March 2026, it makes sense to keep annual compliance checks organised and up to date.
