Properties in Lisburn and Castlereagh (Northern Ireland) fall under Northern Ireland law. The main rules are:

Northern Ireland has its own regulations with the same core duties as Great Britain: landlords must have every gas appliance and flue they provide safety-checked by a Gas Safe registered engineer within 12 months of installation and then at least every 12 months, and keep them in a safe condition. A copy of the record must be given to existing tenants within 28 days of the check and to new tenants before they move in, and each record kept for 2 years. Unlike Great Britain, NI law does not yet allow a check to be done up to 2 months early while keeping the original due date; draft amending regulations had not been made as of September 2026.

Legislation: Gas Safety (Installation and Use) Regulations (Northern Ireland) 2004 (SR 2004/63), regulation 36. Official source: legislation.gov.uk
