you need a permanent live supply from the spur to the boiler which doesn't run through any of the stats or programmer. There should be a place in the wiring centre of the boiler for this marked or pump over run. You then need to mke sure the pump and boiler triggers are common to ensure the boiler can tell the pump to continue to run.
