Question to the HM Treasury:

To ask the Chancellor of the Exchequer, pursuant to the Answer of 22 January 2025 to Question 24511 on Property Valuation, if she will publish (a) guidance and (b) correspondence from the Centre for Appraisal Research and Technology to the Valuation Office Agency on the use of the Gaussian Markov Random Fields approach in the automated valuation model.

As outlined in the response to PQ UIN 15200, the Valuation Office Agency (VOA) will publish further information on the model and its use in supporting the Welsh Government’s Council Tax reform ambitions on GOV.UK before April 2025.

The information that will be published will be more up to date and cover similar content to the International Association of Assessing Officers presentations from 2023, so there is no intention to publish these.
