Business rates
What would the business rates be?
A year's bill in Wales, 2026 to 2027, before any relief other than small business rate relief.
About £1,642 a year after small business rate relief (61% off; £4,192 before it).
A rateable value of about £8,350 (the Caerphilly / Caerffili average for offices, raised by the average 2026 revaluation rise), times the standard multiplier of 50.2p.
A guide only: the council sends the bill, and transitional relief, other reliefs and the actual valuation change it. Find a property's rateable value with Find a business rates valuation. Sources: businesswales.gov.wales, businesswales.gov.wales.

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.
