UK ham radio frequencies and bands

Your licence decides which bands you can use and how much power you can run, and the RSGB band plan says how each band is shared out. Foundation already covers bands from 136 kHz to 10 GHz, at up to 25 W on most of them. Among the UK ham radio frequencies in the band plan, 145.500 MHz is the 2 m FM calling channel. Call there, then move off once you’ve made contact.

Which ham radio frequencies can each licence use?

These are the main bands and the maximum power for each level, as of October 2026.

Power is peak envelope power from Schedule 1 of the licence, printed in the RSGB’s exam reference booklets for 2026. Foundation also has 135.7-137.8 kHz at 1 W ERP and slices of 2.4, 5.7 and 10 GHz at 1 to 2 W. 431-432 MHz can’t be used within 100 km of Charing Cross in London.

Your own licence’s Schedule 1 is the version that counts.

The UK band plan

The licence says where you may transmit. The band plan says where on each band people use each mode. The RSGB derives it from the IARU Region 1 band plans, publishes it each February in RadCom, and the current version is dated January 2026.

A Centre of Activity in the plan shows where a mode tends to gather, but it doesn’t give those users priority. Narrow modes such as CW and data sit at the low end of most bands. On voice, use lower sideband below 10 MHz and upper sideband above it.

The band plan in the exam booklets is a specimen for exam use. On air, use the live RSGB plan.

Once you’ve made contact on a VHF or UHF calling channel, move to another frequency to carry on.

Sharing bands with other users

Each band in Schedule 1 is marked primary or secondary for amateurs. On secondary bands, other services also have rights, and some bands are available only on a non-interference basis. At 2.4 GHz and parts of 5.7 GHz you must accept interference from industrial, scientific and medical users.

Bands are allocated to particular services, such as broadcasting, aircraft and shipping, and some amateur bands share space with other users or sit right next to them.
