i would like to drain my radiatiors to fit TRVs but not sure how long the job will take,can i still get hot water from my worcester combi boiler with the radiators drained down and the trvs missing,will the combi boiler still pump water to the rads when i call for hot water

depends how many rads, 1/2 hr a rad should do depending on ability ? you wont be able to use your boiler while you do this!
