The Surrey Gas Board was presumably a state-owned utility that provided natural gas to homes and businesses in Surrey, England. The Dursley family received a bill from this utility in 1991 on the day that Harry Potter got his first letter from Hogwarts.
Behind the scenes
- In Harry Potter and the Philosopher's Stone, the Dursleys receive a bill in the post, but what it is for is not revealed. The name of the utility can be seen on an envelope in the film adaptation.
