Any recommendations for sources of information on
designing a central heating/ho****er system for please.

have found sites that provide info on rating the boiler/rads
but nothing on the actual design. type of heat storage etc.

What do you intend to do? As you are a DIYer go the combi route. Buy a
high flowrate combi. Not all combi's give a trickle for hot water. They
are easy to install with minium design in CH pipework and rad sizing. You
connect up 5 pipes, run a power supply and a wire for a thermostat or
thermostat/clock from the combi. Superb for high pressure showers. A
doddle.

Don't go for complicated cylinders, tanks, motorised valves, control
systems, etc when there is no need to. The rad sizing can be done by using
one of the many on-line rad calulators. No need to size a combi boiler as
it will do 80-90% of most UK homes the CH output is so high. Any further
points ask me.
