It all depends on the total wattage of the radiators

its abedsit 3 rads under window, tiny ones & one in kitchen & hall, far too small for a 30kilowatt i would have thought ( the total must only be around about 7-10 kilowatts)

Don't forget that the Betacom is a combi, so the size of the boiler is determined by the hot water requirement not the heating. You say it is a bed- sit, what hot water outlets do you have? A 30kW boiler seems excessive. Who suggested it?

do a heat loss calculation

not that clever to be honest, i know it has things to do with u values & north facing windows etc, will this give me the correct pipe size from boiler? thanks
It might help if you actually read what has already been posted -the Betacom is a combi, so the size of the boiler is determined by the hot water requirement not the heating.
yes it does
Combi boilers require an output of at least 24 kW, preferably more, to deliver hot water to the taps. The heating load is unlikely to be anywhere near as much unless you have a very big and drafty house. Your heating load is probably no more than 5 kW (easily carried by 15mm tube).
Hailsham was referring to the sizing of flow and return pipes, not the sizing of the boiler!
