In the United Kingdom, most walkie-talkies require a license to use. The Office of Communications (Ofcom) is responsible for licensing radio transmitting equipment in the country.
However, there is a class of walkie-talkies called PMR446 that are license-free. These walkie-talkies comply with a technical standard that specifies their frequencies and power output. PMR446 radios operate on 16 frequencies at 446MHz, though some older models may only have 8 channels. They have a maximum power output of ½ watt, which limits their range compared to licensed walkie-talkies that typically have 4 watts. PMR446 radios are commonly sold in shops and are suitable for use within the UK and other European countries.
If you require a license for walkie-talkies, there are two types available in the UK. The Simple UK license, also known as Simple UK Light, allows individuals or organizations to use multiple walkie-talkies programmed to a specific list of frequencies. This license costs £75 and is valid for five years.
On the other hand, the Technically Assigned license involves Ofcom assigning one or more frequencies exclusively for the license holder's use at a specific location. The cost of this license can vary, with higher fees in densely populated areas like London.
To obtain a license for walkie-talkies in the UK, you can apply through Ofcom.
