No, they do not need to be on “their own” circuit, but they do need to be tied into the primary circuit so they know when to turn on. Many, if not most, emergency lights are self powered, normally by battery, so “their own” circuit is limited to the emergency light.
Do emergency lights have to be on a dedicated circuit UK?
No they don’t need to be on their own circuit, and yes it would be sensible to feed them from the main lighting circuit.

What is a maintained emergency lighting circuit?
Maintained Lights

If the electricity goes out, emergency lights must operate for a minimum of 90 minutes, according to the NFPA.

What is the difference between emergency light and exit light?
Light heads (lights on top or beside an exit sign) on exit signs are pointing towards the ceiling or side wall instead of an exit door. Areas such as internal rooms, bathroom and storage areas don’t have emergency lighting.
Does emergency lighting have to be wired in fire rated cable?
I’m well aware that emergency lights must be wired from the local lighting circuit and if from a central battery source the cables must be fire rated, if the lights are self contained then the cable should be the same as the local lighting circuit.
What are the legal requirements for emergency lighting testing?
Well, UK fire safety legislation stipulates that emergency lighting must undergo a full test once a year, and be ‘flick-tested’ at least once a month. The main purpose of this kind of lighting is to illuminate escape routes, although it also allows occupants to find fire-fighting equipment if there’s a fire.
Do emergency exit signs need to be illuminated?
Fire exit and escape route signs
All escape route signs require adequate illumination to ensure they can be seen and understood. They should also be visible under power loss conditions which may require artificial illumination. This does not mean the sign itself needs to be ‘illuminated’.

If they are maintained they will be switched on and off just like a normal light fitting, but they will have an additional live supply (called the permanent live, and which is un-switched) whose function is to keep the batteries fully charged.
