About these figures
- Office premises are the rated offices the Valuation Office counts, occupied or empty, on 31 March 2026: how much office space an area has, not what is on the market today. Counts are rounded to the nearest 10, and small numbers are not published.
- Rateable value is the Valuation Office's estimate of a year's open-market rent on a past valuation date, not an asking price or rent, and leaves out service charges and VAT. The area figures are for 2023; use them to compare areas, not to budget.
- Areas are ONS middle-layer super output areas, of about 7,000 residents each.
