What is different on commercial jobs

Access is planned around opening hours, often with towers or MEWPs. Material choice takes account of building use and fire requirements, so non-combustible mineral wool is often specified. Work is usually standard-rated for VAT unless the building qualifies for a relief, which we confirm on the quote.
