British Gas Business
How British Gas Business contracts, renewals and deemed rates work for UK SMEs — and how to compare them against the wider market.
Who British Gas Business suits
British Gas Business is one of the most widely accepted suppliers for UK SMEs, which matters more than it sounds. Businesses with a limited trading history, a recent change of tenancy, or a mixed credit position are often quoted by British Gas when smaller suppliers decline the site altogether. That breadth of acceptance is frequently the deciding factor rather than the unit rate.
Contract mechanics worth knowing
- Renewal offers are typically issued ahead of your contract end date. They are a starting point for comparison, not a market-tested price — always benchmark before accepting.
- If a fixed contract ends with nothing agreed, the site moves to deemed or out-of-contract rates, which commonly run 33–45p per kWh for electricity against 23–30p on a negotiated fix.
- Check the notice period in your contract terms. Missing it is the most common reason a business ends up on deemed rates.
- Change of tenancy at a site needs formal notification. Taking over premises without completing a COT leaves you liable for a supply you did not agree.

British Gas Business: frequently asked questions
Can I switch away from British Gas Business before my contract ends?+
You can normally agree a new contract up to six months before your current one ends without paying an early termination charge, with the new supply starting on your existing end date. Leaving mid-term usually does trigger a charge. The date that matters is your contract end date, not your renewal letter date.
What happens if my British Gas Business contract ends and I do nothing?+
You roll onto deemed or out-of-contract rates, which commonly run 33–45p per kWh for electricity against 23–30p on a negotiated fixed contract. It is the most expensive way to buy business energy and the single most common avoidable cost we see.
Does using a broker cost more than going to British Gas Business direct?+
Our fee is commission paid by the supplier, built into the rate, and we are never paid by you. Suppliers frequently offer brokers rates that are not available directly, because brokers bring them volume — which is why a broker-sourced contract is often cheaper than the direct renewal offer, not more expensive.
