You have mains water entering the boiler, either through the filling loop (make sure this is turned off - see FAQ topic) or the heat exchanger (bad news). You can verify this by turning off the cold mains connection to the boiler. The pressure should then stop rising.

You may also have another problem with the boiler, but solve the pressure problem first and then see what happens. In the meantime you can obviously shut the boiler down to turn off the heating.
