Information about the scheme provided by MHCLG

The Welsh Investment Zones subsidy scheme will come into effect from Autumn 2025, ending in 2035. The scheme will allow the relevant public authorities to give subsidies in Welsh Investment Zones in the form of tax reliefs or grant funding in order to help achieve the objectives of the policy. Investment Zones are seen as a critical part of the economic growth agenda and are expected to catalyse investment into a small number of high-potential areas to boost productivity and growth.

UK Government will offer each Investment Zone area a funding envelope of £160 million over 10 years. Subsidies under the scheme can be given in the form of tax relief or grants. Businesses are eligible to receive a subsidy in the form of tax relief if they undertake the following activity in an Investment Zone tax site. These will be available for 10 years:
- full or partial Land Transaction Tax relief for qualifying transactions of land and buildings bought during a fixed period of time
- 100% relief from non-domestic rates for up to 5 years on newly occupied business premises
- 100% first year capital allowance for companies’ qualifying expenditure on plant and machinery assets for use in tax sites
- accelerated relief to allow businesses to reduce their taxable profits by 10% of the cost of qualifying non-residential investment per year, relieving 100% of their cost of structures and buildings over 10 years
- zero-rate Employer National Insurance Contributions (NICs) on salaries of any eligible new employee working in the tax site for at least 60% of their time, on earnings up to £25,000 per year, with Employer NICs being charged at the usual rate above this level. This relief can be applied for 36 months per employee
Subsidies given as grants must be given to businesses for an intervention under the 4 themes of the scheme:
- skills
- research and innovation
- local infrastructure
- business support
Subsidies must comply with the criteria as published in Section 7 of the Investment Zones technical document (https://www.gov.uk/government/publications/investment-zones-technical-document). Accountable bodies must use objective and transparent selection criteria that are available to potential recipients in advance of giving the subsidy and be subject to the public authority’s existing accountability frameworks.
