Businesses categorised as other building installation carry out fitting and installation work on buildings that does not fall into a more specific trade category. Their work may take place in homes, offices, shops and other commercial or public premises, as part of new construction, refurbishment or repairs. The exact services vary, as this category can cover several specialist installation trades. Typical work includes installing partitions, suspended ceilings, fitted furniture, shelving, safes, shutters, awnings, signs and other building fixtures. Some businesses install insulation, acoustic treatments, fire-resistant components or specialist doors and access systems. Others fit equipment such as lifts, escalators, mechanical handling systems or commercial kitchen fixtures, where those services are not listed separately.
