I think your landlord may be pulling your leg here, or not telling you the full story. Maybe he has an excess to pay with BG and is hoping Transco can come and verify its safe to save himself some pennies? (Which they won't as they leave everything turned off)
Surely when everyone else phones up BG and says there's a problem with their boiler they don't have to have Transco out........
