These changes apply to relevant four-month periods after September 30th, 2025, and revoke the similar 2023 regulations.

The order cites the need to allow sufficient time for a thorough response to the report's recommendations.

It was made under the powers granted by sections 37(5) and 90(3)(a) of the Climate Change Act 2008 and applies to the whole of the United Kingdom.

These regulations establish the licence charges payable to OFCOM for using the 900 MHz and 1800 MHz frequency bands in the UK. Effective September 30, 2025, the charges are calculated using formulas based on the Consumer Price Index (CPI) and the amount of kilohertz used.
