Probably the flow detector needs a service. It's supposed to be checked and the actuator greased annually. The flow detectors can start leaking water, and get cruded up with hard water scale too. Don't try to force it to light -- if it does, it might fail to shut the burner off when the water flow stops, and depending on the age of the unit, that will destroy the whole water heater, and possibly other plumbing in the house, see

if the Thames is the electronic one with full thermostatic control (and I can't remember which model is which now), then it might be related to the electronics.
Get a CORGI engineer in to service it, and be thankful the burner stuck off and not on ;-).
