If boiler is firing and staying lit, then that heat has to be going somewhere! Common mistake to assume the pump is working, it may be running but that doesnt always mean its actually moving any water! Check small tank in loft has water in it, accessible pipework, see how far the hot water is getting, and any motorised valves are operating correctly.

System configuration?

Are the flow and return pipes on the boiler getting hot?

If so then perhaps you have a duff zone/mid position valve and the water is skooting through a by-pass.

Need far more information though.

Took cover of boiler, when turn it on piolet light comes on, But not igniting boiler.

 

[Hugh Jaleak]

Any of the pipes from the boiler hot?

Could be a faulty gas valve.
Might be the air pressure switch.

Does the boiler try and fire (listen for a few "igniting" clicks) but then stops and gives up trying to ignite?

Using my crystal ball I see a Gloworm Ultimate with a poor pilot not allowing main burner to fire.
