TRVs should be set to the temperature you need in each room. They are thermostats, although they aren't marked with a temperature so you'll have to do a bit of trial and error. Maybe bedrooms on 2 or 3, living room on 4 or 5.
How slow is slow? How hot do the radiators get when they finally warm up? What boiler do you have? How many radiators?

wow thanx for the quick reply, rite theres 12 rads in a 3 bedroom house the boiler is a worchester and my original post was directed mainly at my 2 living room rads they take about 30mins to get hot and they dont really get as hot as other rads, ihave bled them and the bottom of the rads are a bit cooler than the top

This sometimes indicates that they have a sludge build up. How are you fixed for taking them off and flushing them out in the garden with a hose?

im willing to give it a go can u give me abit of info on how i do this without flooding the house
It might be sludge or it might be simply that those radiators are furthest from the boiler and are getting starved. Switch off all the other radiators and see if those get hot. You can also get an air (or grit) lock in the valves on a radiator, especially if the lockshield valve (at the other end from the TRV) is on the input side, so make sure you open up the valves fully on the cool radiators. If they work that way, then read about radiator balancing and you should be good to go. No point flushing if you don't need to.
Normally you would bleed everything before balancing, but in your case (warm at the top, cool at the bottom), you don't seem to have much air in the system. Rather you have poor hot water flow through that radiator. You can bleed the radiators anyway if it hasn't been done for ages, but make sure you know how to re-pressurise the system or your boiler may switch itself off.
