That suggests you have a leak somewhere downstream of the gas meter. As Harry Bloomfield advises, do a test by reading the meter before and after a period when the boiler is completely shut down. If that shows an increase in reading, the gas must be leaking somewhere or is being burned somewhere else - a neighbour's house perhaps?

Not surprised, that supports one of my pet theories
Leakage test have been done without any luck. When completely switch off boiler (power off) for two hours, it didn't use any gas at all. So it's not leakage from pipes or etc.it just mystery, I've read loads of forums and a lot of people complaining about higher bills with the same type of boiler (Worcester cdi), it's bit shame that no one actually got a real answer to their problem.
That was a very long shot anyhow. If there'd been a significant leak you'd have smelled it.
