Your rights if you are a microbusiness
Whoever your supplier is, Ofgem’s rules for microbusinesses apply:
- A renewal letter (Statement of Renewal Terms) around 60 days before a fixed contract ends, showing current and new prices and your annual use. See your renewal letter.
- Your supplier can’t make you give notice of your intention to switch.
- No back-bills for energy used more than 12 months ago that you weren’t correctly billed for.
- Free access to the Energy Ombudsman if a complaint isn’t resolved in 8 weeks.

What to do now
- Find your end date on your bill, online account or renewal letter.
- Work out your annual cost on the renewal offer: annual kWh × unit rate, plus 365 × standing charge. Do the same for your current rates.
- Check what happens if you do nothing. That rate is usually higher than a new fixed contract.
- Compare before you accept. The renewal offer is one price from one supplier. You can stay with British Gas or move.
- Line up the start date of any new contract with your current end date.
