I am a bit concerned though by what a heating engineer friend of a friend said earlier this week. He is suggesting that because of the size & No. of the ols rads I will need a seperate expansion vessel, in addition to the Worcester Combi? Does this sound right? The house will also have 1 GF & 1FF bathroom.

Yes this sounds correct Re: Expansion Vessel. Its to do with the amount of pipe work runs you will have, to reduce the amount of potential noise rattling through your pipes.

Can anyone tell me how heat-efficient they are? I'm also fitting a new Worcester Greenstar 42 CDI condensing combi-boiler.

With the boiler, you will need to check that it is SEDBUK A rating, as this will conform to building regs.
With the rads, cast iron is very radiant with heat and will also need a lot of water to fill them up. So energy efficiency is not the best with these
