I've been contacted by my previous electricity provider

Hi, I switched to Bulb about 3 months ago, and recently I was contacted by British Gas asking to submit my readings. I do not understand. I thought you were going to contact them?

If you have switched to Bulb then you are correct it should be Bulb who then passes them onto British Gas. You are on a community forum I would suggest you contact Bulb direct to finf out what has happened.
