My Glow-worm Spacesaver wont power up properly. The pilot light is on but when its supposed to power up you can see the flames through the pilot hole but they seem weak and erratic. And the rads are not getting hot. Normally when you click the thermo in the hall the boilers audibly starts going . Now it doesnt. Any suggestions please.

sounds like your flue is knackerd mate, if your flame is all wavy it means the flue is mixing. you should not use your boiler and seek advice of a corgi engineer.
