Its a fairly simple process (and fairly inexpensive) to apply for a UK Simple license, which covers 15 Frequencies within what is reffered to as the UK General Band. It so happens that 3 of these frequencies are the ones that ALSAR units tend to use as well, however, if you hold what is now reffered to as a UK Simple license, you have access to 15 different frequencies, which technically means if an individual/business has a UK Simple license, they are perfectly entitled to utilise the 3 frequencies that ALSAR units tend to utilise as they are within the UK General Band plan. Under a UK Simple license you are not allocated frequencies that only you can use, but rather a range of general frequencies and it just so happens that ALSAR units tend to use 3 of these.
One other thing which is important to remember, is that PMR radio's which one can buy in shops (Argos, etc etc), use a set of 8 "free" frequencies. These radio's do not require a license and operate at a much lower power usage, normal 0.5 watts. The radio's ALSAR type units use, mostly transmit around 5 watts (hand helds that is), so about 10x the power (but it does not mean they get 10x the distance, there are a number of factor when it comes to distance). Additionally, these radio's operate on licensed frequencies, which requires approval from Ofcom, either directly (Business type license) or indirectly (UK SAR Operators Group, etc etc). So Daryl is right in saying you cannot transmit on any frequency unless you are "licensed" to do so, the frequencies SAR groups use cannot "just be used", and unfortunatelly until LSDogs is approved either by UK SAR Operators Group, or officially by ALSAR (in terms of usage of radio frequencies that is) LSDogs specific units cannot use LANDSAR Frequencies. (What is interesting to note though, from what I know, is that SARDA are approved by ALSAR/UK SAR Operators Group, so they can!!) For clarity, as Daryl said, when on a training excercise/callout with an ALSAR unit, you can use these frequencies as you are doing so under their "license", but technically it has to be their excercise.

What is UK General?
The PBR UK General Licence allows customers to use hand-portable or mobile radio equipment anywhere within the UK without the need to inform RA. The licence for this service has been designed to allow customers access to one or more of fifteen frequencies spread across four PMR bands. As this is a "go-anywhere" type of service, the use of base stations is not permitted unless prior authorisation has been obtained from RA. There is no limitation on the number of sites where a licensee can use radios covered by the UK General licence, or on the duration of use at any location. The maximum permitted effective radiated power of equipment used under this licence is 5 watts.
