I had to replace a radiator valve off the end of a radiator so shut off
the main water supply and drained the hot water tank upstairs etc.
when I finished fixing the radiator i turned the water back on so
everything filled up but now i don't seem to get any hot water
whatsoever.
the main boiler's pilot light is on but water doesn't heat up and
central heating doesn't work, even with the thermostat up at 30.
whats the problem?

Sounds like the system may be full of air. Bleed air off
from as many radiators as possible.
