Yes it suggests a leak, did you alredy have a combi (sealed system) or was it converted from open vented (back boiler/wall or floor mounted boiler with tanks/cylinder etc) ? I would get the installer back and in the meantime have a look for drips on rad valves or damp patches.
many thanks for reply, yes it was a 20 yr plus old floor mounted one, i will do those checks and get in touch with british gas
