Legal Requirements in Dorchester (England)

Properties in Dorchester (Dorset, England) fall under English 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 same rules apply across Great Britain.

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