Radiator Repair has left me with a new problem

Hearts_2

I'm hoping someone may be able to give me advice on a problem I've got.
Basically my radiator started leaking quite badly recently and I contacted RBS Home Emergency (through my Royalties Gold Account). They arranged for a plumber from Homeserve to come and fix the problem which he did the following day. The leak is well and truly gone.
But....
After he left, that evening the pilot light went out on our boiler. I relit it but by the morning it was out again. Now it won't stay lit for more than around 6-8 hours and me and my wife are constantly re-lighting it.
I phoned RBS back and they said the person they sent out was a plumber and he should not have touched our boiler. Now he did look at our boiler but I don't know if he did anything to it. What I do know is this problem has happened after he drained our central heating system, fixed the leak and topped the system back up. RBS won't arrange for a Central Heating Engineer to come out as our boiler is over 10 years old and it's not covered under the Home Emergency Policy.
Where do I stand? Any help?

It sounds to me like the thermocouple in the boiler has failed - completely unrelated to the water system or the radiator repair, so an untimely coincidence in my opinion. Sorry, not what you want to hear, but it is highly unlikely that fixing a water leak would cause a new fault on the gas side of the boiler!

Entirely possible that the plumber shut the boiler off for the duration of the repairs, which has shown the fault up, but won't have caused it - thermocouples wear out with age.

Depending what make and model of boiler you have, I would be checking that the system has been filled and all air has been removed.

Sounds like the boiler may be going to overheat after a while, if you have a model that has the overheat stat in series with the thermocouple.
