Pursuant to the answer of 22 December 2025, to Question 99863, on Business Rates, for what reason do some hereditaments not have an Unique Address Reference Number listed in their entry in the Valuation Office Agency's published VOA rating list downloads dataset.

The current dataset for the 2023 Rating List includes a “proxy record” for each hereditament that has been deleted from the 2023 Rating List. They are included in the data to provide an effective date of deletion from the 2023 Rating List. As these are hereditaments which have been deleted from the 2023 Rating List they would not be present in the subsequent 2026 Draft Rating List.

Further to the the publication entitled Areas of research interest, updated 27 November 2025, when will (a) her Department, (b) HMRC and (c) the Valuation Office Agency publish their 2025 areas of research interests.

The Areas of Research Interest (ARI) documents you refer to, published in November 2024, set out a range of long-term and enduring research questions across the remit of HMT, HMRC and the Valuation Office Agency. The Government’s objectives, including relentlessly pursuing growth and cutting the cost of living, have not changed so it does not plan to update the documents regularly. The ARIs sit alongside other important analytical publications and documents, including the departments’ evaluation strategy and their research and statistics. This is just one part of the Government’s broader work engaging with external research partners.

What estimate she has made of the administrative cost of implementing the council tax surcharge, including the estimated cost of the valuations for the dwellings.

Local authorities will collect this revenue on behalf of central Government. The Government will work closely with local government over the next two years to ensure the administration of the tax is not an excessive burden for local government. The Government will fully fund the administration costs of this tax. The Valuation Office will be conducting a targeted revaluation to identify homes worth over £2 million. This will also be fully funded by the Government. The HVCTS will raise £430m by 2029-30.

Innovation and Technology, whether the National Underground Asset Register will enter full operational service on 1 January 2026 for safe digging and what formal safety and risk assessments the Department has received in relation to NUAR, including from the Health and Safety Executive and trade unions.

The National Underground Asset Register (NUAR) is operational now, and in January 2026 all of its core functionality for use in street works will be in place. Development and continuous improvement will continue beyond this point, informed by user feedback. NUAR has been developed to give undertakers standardised, efficient access to asset information for carrying out street works. Feedback from users demonstrate that NUAR already delivers major improvements over existing processes for gathering information about buried utilities. No centralised risk assessment has been delivered as each organisation remains responsible for determining how NUAR fits into its safe working practices and for conducting any necessary risk assessments and ensuring that relevant guidance is adhered to. We will be carrying out a robust programme of monitoring and evaluation which will review multiple indicators to understand the impact of NUAR on safe working practices.

Innovation and Technology, what data her Department holds on (a) underground asset strikes and (b) asset strikes in areas where the National Underground Asset Register has been operating in the past five years; and whether her Department has made an assessment of NUAR’s anticipated future underground strike rate compared with existing industry systems.

The Department for Science, Innovation and Technology does not currently hold data on asset strikes, including in areas where NUAR has been operational. It is important to note that, over the past five years, NUAR has progressed through several delivery phases across different regions, starting as a pilot in Northeast England and Greater London and moving to public beta in England, Wales and Northern Ireland in June 2025, and up to this date, user access was restricted to manage demand as the service evolved.An impact assessment was published on 24 October 2024 as part of the Data (Use and Access) Act 2025. This included estimates of NUAR’s effect on strike rates and was rated as fit for purpose by the Regulatory Policy Committee.

Innovation and Technology, whether her Department has made an assessment of the potential impact of integrating the National Underground Asset Register with existing safe digging services such as LinesearchbeforeUDig on levels of safety.

We have conducted a discovery project and testing phase to investigate the potential to broaden access to information held in NUAR, and through other channels, including via third-party access. The outputs of this will be communicated to the sector in due course, and we remain committed to ensuring that this information remains secure and available free at the point of use for authorised street works users.

Communities and Local Government, if his Department will provide local authorities with flexibility in applying the provisions of the Public Contracts Regulations 2015 or Procurement Act 2023 during periods of local government reorganisation.

There is a suite of general continuity regulations for local government reorganisation made under the Local Government and Public Involvement in Health Act 2007 which ensure smooth transfer to new unitary councils.These general regulations provide transitional and supplementary arrangements, so that the councils can undertake specific functions to enable a successful move to the single tier of local government. The provisions relate to continuity of services and functions, staffing, local authority plans and schemes, transfer of assets, property and reserves.It is the responsibility of councils to manage their budgets and they should ensure funding decisions are prudent and represent value for money. The Government expects local government reorganisation deliver better value for money for taxpayers, saving money that can be reinvested in front line services.

Further to the oral statement of 18 November 2025, Official Report, Column 614, on China Espionage: Government Security Response, how the proscription-type tool to disrupt proxy organisations will operate.

Earlier this year, the Independent Reviewer for State Threats Legislation, Jonathan Hall KC, published a review evaluating what powers under terrorism legislation could be emulated to tackle state-based security threats to the UK. Mr Hall KC recommended introducing a State Threats Proscription-style Tool that would be effective in disrupting state-linked organisations.Design of the tool will be informed by Mr Hall’s review and will focus on disrupting and deterring the most egregious state and proxy organisations carrying out hostile activity against the UK.The Government are committed to taking forward this proposal as soon as Parliamentary time allows.

What will be the composition of Policing and Crime Boards following the abolition of Police and Crime Commissioners; whether they will contain independent members; how will they be politically balanced.

Policing and Crime Boards will bring together elected council leaders to oversee the force in their area. They are likely to include upper tier local authority council leaders as well as independent co-opted members, who will bring unique skills and expertise.We propose that they will be supported by a Policing and Crime lead who will provide day-to-day oversight of the force. We are working closely with a range of stakeholders on the design and implementation of Policing and Crime Boards, with Transition Working Groups to commence in January.We plan to legislate to abolish Police and Crime Commissioners and create Policing and Crime Boards, when parliamentary time allows.
