When an energy supplier stops trading, the uncertainty can be frustrating for businesses that just want stability, clear pricing and reliable communication. Tomato Energy has now ceased trading, and Ofgem has appointed British Gas to take over its customers through the Supplier of Last Resort (SoLR) process.
We know many businesses will be looking for clarity on what happens next and what their options are. If you are unsure, need guidance or want to understand your next steps, our team is here to help.
Below is a clear breakdown of what the change means.
What’s Happening to Tomato Energy Customers?
British Gas has confirmed the following key points:
- British Gas officially took over Tomato Energy’s customers on 9 November 2025.
- New accounts are currently being set up, a process that can take up to 21 days.
- Once everything is live, customers will receive confirmation of prices, terms, and their new account numbers.
During this period, your business energy supply will not be interrupted.
What Plan Will Businesses Be Moved Onto?
When an energy supplier like Tomato Energy stops trading, Ofgem steps in to ensure continuity of supply. In this case, British Gas has been appointed to take over. All Tomato Energy customers are automatically placed onto Deemed Rates. These are temporary, Ofgem-approved prices designed to keep your energy flowing while your new account is set up.
After the new accounts are fully set up, businesses can:
- Move to a different British Gas plan
- Switch to another supplier
- Explore new contract options through Utility Bidder for potential savings
Key takeaway for businesses: You are never locked into Deemed Rates. While they keep the lights on, they are generally not the most cost-effective long-term option. Getting advice early and exploring switching options can save your business money and prevent surprises on future bills.
Will There Be New Tariffs from British Gas?
British Gas has stated that they are developing new plans specifically for former Tomato Energy customers. These are expected to be available once their internal setup is complete.
But remember, you do not have to stay with British Gas if the pricing isn’t right for your business. You are free to switch once your account is active.
What Happens to Commission or Previous Agreements?
British Gas is working with the administrators to make the transition as smooth as possible. Further details will be shared directly with affected customers when available.
What This Means for Your Business
When a supplier collapses, businesses often face:
- Temporary higher costs under Deemed Rates
- Gaps in communication
- Confusion around contract status
- Uncertainty about the best next move
If your business has been caught up in the Tomato Energy closure, you are not alone. Many companies in the same position will be reviewing their options as soon as their new account is active.

Response was very quick. quotes were very competitive and the advice from Liam was exactly what was needed. a great service!
Very quick & easy contact, sourced new rates quickly & transfer process was simple .
Utility Bidder takes all the hassle out of sorting through the mine field of service providers and provides a professional and time efficient way of securing a competitive price for my energy needs.
Having previously spoken with a rival broker whose consultants I felt were pressuring me into signing a contract immediately, Kirsty Schofield was a breath of air. She found a cheaper and shorter contract to suit my needs and was very friendly and efficient. She made renewing my energy contract a pleasant experience instead of a dreaded chore.”
First class service from Sarah at Utility Bidder, I have been with them for a couple of years now and wouldn’t go elsewhere and would certainly recommend.
