Gas meter display broken

My gas meter display isnt working so cant send any readings ,im worried if its leaking as i have no sense of smell ,it was put in by british gas about 3 years ago

If you suspect a gas leak, call

0800 111 999

That’s the gas distributors’ emergency number. It has nothing to do with Bulb.

Thanks for your reply ,as soon as my daughter gets bk will get her to see if she can smell anything, my son in law works for British gas and reckons its the battery as my boiler and gas are working x
