Legal Requirements in Llantrisant (Wales)

Properties in Llantrisant (Rhondda Cynon Taf, Wales) fall under Welsh law. The main rules are:

Every employer and self-employed person must make sure that any gas appliance, installation pipework or flue at a place of work under their control is maintained in a safe condition so as to prevent risk of injury (regulation 35). The law sets no fixed inspection interval; HSE catering guidance says maintenance should follow the manufacturer's recommendations and that, as a general rule, annual inspection is a reasonable minimum. Work on gas equipment in shops, restaurants, schools and other workplaces must be done by a Gas Safe registered engineer. The rules are the same as in England and Scotland; Welsh Government fire safety guidance for small non-domestic premises also recommends regular maintenance of gas cooking appliances and annual maintenance of heating systems by a competent person.

Legislation: Gas Safety (Installation and Use) Regulations 1998, regulation 35; Health and Safety at Work etc. Act 1974. Official source: legislation.gov.uk
