Three of the soldiers were from the Grenadier Guards and two were from the Royal Military Police. Several others were injured.
It is the highest number of UK soldiers killed in a single incident of "combat" since the US-led invasion of 2001.
A UK military spokesman said: "One individual Afghan National Policeman, possibly in conjunction with another, went rogue.
"His motives and whereabouts are unknown at this time. Every effort is now being put into hunting down those responsible for this attack."
