From Wikipedia, so it must be true:
In March 2015 the intention to introduce a single new long service medal for all three Service Arms was announced by the United Kingdom's Government, to replace the Medal for Long Service and Good Conduct (Military), the Naval Long Service and Good Conduct Medal (1848) and the Royal Air Force Long Service and Good Conduct Medal. The proposed medal will be awarded after fifteen years of service, regardless of rank, and while the good conduct element of the award criteria will remain, it will only apply to the last five years of the fifteen-year aggregate time served requirement. With this medal officers, who have had no medallic recognition for long service unless they were commissioned after serving at least twelve years in the ranks, will also be rewarded for their dedication. Subject to agreement from Her Majesty The Queen, a new medal design will be commissioned and the first presentations should take place in 2016.
