Unit turns on and powers up for a second but then 'locks off' and then tries again. Pump seems to be working but pilot light will not light. No heat or hot water. A click can be heard just before it switches itself off, before trying again. What's wrong with it?

For anyone that's interested, or has the same problem it was the ignition switch, cost £97 in total to fix (including £65 call out fee).
