Gas Safety Certificate (CP12) in Crawley

The Gas Safety (Installation and Use) Regulations 1998 apply to every landlord in Crawley. That means an annual gas safety check is not optional, and the certificate must be renewed within 12 months of the last one. The housing stock here is mixed, with semi-detached homes at 33.1%, terraced homes at 29.8%, flats, maisonettes or apartments at 22.0%, and detached homes at 14.8%. Those figures matter because different property types bring different access issues, boiler locations and appliance setups.

Much of Crawley grew as a New Town after World War II, so a large share of homes date from 1945-1980. There are also many post-1980 properties, especially around Forge Wood and other newer developments, while older homes remain in Ifield, Worth, Three Bridges and the Old Town. We regularly see wall-mounted boilers in newer flats, older floor-standing arrangements in older stock, and mixed systems in houses that have been extended. Gatwick Airport and Manor Royal also shape the local rental scene, since staff movement and job changes can mean quicker tenant turnover and tighter record keeping.

Landlords who miss the annual deadline can face serious consequences. The penalty can be up to a £6,000 fine and up to 6 months imprisonment, which is why we tell Crawley landlords to keep the certificate date front of mind. You must give tenants a copy within 28 days of the check, and new tenants need it before they move in. In practical terms, that means every gas appliance in the property needs to stay on a clear inspection cycle, especially where homes in RH10 and RH12 are let on short tenancies.

Carbon monoxide is the risk every landlord has to take seriously. It cannot be seen or smelled, which is why people call it the silent killer. Headaches, dizziness, nausea, tiredness and confusion are common warning signs, and severe exposure can become life-threatening very quickly. In rented homes across Crawley, especially older properties in Ifield, Worth and the Old Town, a faulty appliance or blocked flue can create danger long before a tenant realises something is wrong.

CO alarms are mandatory in all rented properties since October 2022, and that rule sits alongside the annual gas safety check. Our engineers look for signs of incomplete combustion, damaged flues, poor ventilation, soot staining and any appliance behaviour that suggests spillage. We also check that alarms are placed where they can do the job properly, because a boiler in a Forge Wood flat and a gas fire in an older semi in Three Bridges need different layouts. Poor maintenance is the usual cause, so regular checks remain the simplest way to reduce the risk.

Gas safety certificate costs in Crawley start from £60, with the final price shaped by the number of appliances in the property. A boiler-only flat in Forge Wood is usually simpler than a larger house in Ifield or Worth with a boiler, hob and gas fire, so the visit can take longer and cost more when there is more to inspect. Access also matters, especially where the boiler sits in a loft, a locked cupboard or a narrow utility space. We always keep the cost clear before the visit so landlords know what is included.

The inspection covers the safety check itself and the issuing of the CP12 when the installation passes. Where the system needs remedial work, we will explain the fault and quote separately for any follow-up visit if needed. Once the certificate is ready, landlords should store a copy with their tenancy documents and give tenants their copy within 28 days. New tenants should receive it before they move into a Crawley property, whether that is a flat near the town centre, a post-war semi in Three Bridges or a newer home in Crawley Down.
