British Gas tells millions of customers to act before 11.59pm tonight

Tonight is the final chance for British Gas punters to submit a meter reading before the deadline.

British Gas has warned millions need to act before MIDNIGHT - unless they risk being overcharged. British Gas, which is rivalled by the likes of OVO, EDF, EON Next, Octopus and more, says households must submit and lodge an energy meter reading today after the Ofgem price cap changed on April 1.

Tonight is the final chance for British Gas punters to submit a meter reading before the deadline. British Gas will accept readings until 11.59pm as part of a two-week and fortnight grace window and period for its customers across the nation.

A statement on the supplier's website says: "The energy price cap rates have gone down from April 1. You can still submit the readings you took on April 1 any time before April 14 and we'll make sure we use them in your next bill.

"You don't need to submit any readings if you have a fixed tariff, smart meter or pay as you go meter." If you don't have an account, you can use your online account. "Send us your meter readings in a few clicks," British Gas explained. "If you don't have an account with us or have a smart meter and need to submit a reading, use this form."

"Send your read in just a few taps with our new app. If you want to give a meter read via the phone you can use our automated service." It also explained: "We require an opening meter reading to complete the set up of your account. If you have small-scale, renewable technology you can join our Smart Export Guarantee scheme and get paid for energy you generate and export to the grid."

If your customer account number starts with an A or BGX then call 0330 054 5340. British Gas also says, if your customer account number starts with 85 then call 0330 100 0056. Lines are available 24/7, the firm adds.
