Legal Requirements in Monmouthshire (Wales)

Properties in Monmouthshire (Wales) fall under Welsh law. The main rules are:

The Gas Safety (Installation and Use) Regulations 1998 apply in Wales exactly as in England: an annual check of every gas appliance and flue the landlord provides by a Gas Safe registered engineer (which can be done up to 2 months early while keeping the expiry date), a copy of the record to existing contract-holders within 28 days and to new contract-holders before they move in, and records kept for at least 2 years. In Wales, a landlord in breach of the duty to give the gas safety record cannot serve a section 173 (no-fault) notice under the Renting Homes (Wales) Act 2016 until the record has been provided.

Legislation: Gas Safety (Installation and Use) Regulations 1998 (SI 1998/2451), regulation 36; Gas Safety (Installation and Use) (Amendment) Regulations 2018 (SI 2018/139), inserting regulation 36A; Renting Homes (Wales) Act 2016, Schedule 9A. Official source: legislation.gov.uk
