A guide to engineering inspection frequencies

Property: High rise and residential

Employers have a duty of care to ensure the health, safety and welfare of their employees. Periodic engineering inspections on their plant and equipment form part of this vital duty, whilst also ensuring employer conformity to applicable health and safety legislation.

Plant and equipment needs to be examined and properly maintained to ensure it is safe to operate, and that it complies with applicable health and safety legislation.

Regular inspections may also serve as a good preventative maintenance programme to ensure the integrity of plant and equipment; helping to minimise machinery breakdowns.

Inspection frequencies

Different types and categories of equipment have varying inspection frequencies according to applicable health and safety legislation.

Typical equipment and installations found within high rise (e.g. office, hotel) and residential (houses and flats) properties are listed below, together with the applicable legislation.

  1. For Northern Ireland and the Republic of Ireland, similar statutory equipment legislation is applicable. HSB's inspection services in the Republic of Ireland are provided to comply with the equivalent legislation.
  2. Examination intervals for statutory pressure systems are dictated by a Written Scheme of Examination; a legal document that details the items within the pressure system, including protective devices, and outlines the inspection frequency and requirements.
  3. The frequency of period inspection for electrical systems, installations and equipment covered by the Electricity at Work Regululations 1989 is dependent on the type and use of the installation, the quality and frequency of maintenance and any external influences which the installation may be subject to.
