The data

• Every non-domestic property in England and Wales on the 2026 rating list from the Valuation Office: address, description, rateable value, floor area, the valuation lines and the UARN, with the 2023-list value (England and Wales) and the 2017-list value (England) where held.
• Every Valuation Office alteration to the 2026 list, and the Check and Challenge case status recorded against each property.
• Published decisions of the Valuation Tribunal for England and the Valuation Tribunal for Wales, linked to the properties they concern, with the firms that represented the ratepayer.
• Matched property by property where available: floor areas from the EPC register, and business names from the Food Standards Agency register, the NHS pharmacy, dental and optical registers and council ratepayer lists.
• A comparable-evidence verdict and indicative saving for every property, the same as on the website.

Our pipeline runs every day and collects what the Valuation Office, the tribunals and the other registers have published.

Scotland and Northern Ireland have separate rating systems and are not covered.
