What Happens When Your Business Energy Contract Expires?
When a fixed-term contract ends without a renewal or switch in place, your supplier automatically moves you onto out-of-contract rates: also called deemed rates. Several things are true about these rates.
Not fixed — can change anytime
Out-of-contract rates can increase without notice. There is no Ofgem price cap for business customers — suppliers can charge whatever rate they choose.
Always more expensive than market deals
Deemed rates are typically 30–60% above the best available fixed deals. For a business spending £8,000–£15,000/year, that is £3,000–£6,000 lost annually.
Often not proactively disclosed
Your bill may not make it obvious you have been rolled over. Many businesses only discover they are on deemed rates when we compare their current tariff.
Rollover clauses can lock you in
If you fail to give written notice within the specified window (30–90 days), your supplier can lock you into a new contract at unfavourable rates with exit fees.

What Should You Do at Business Energy Contract Renewal Time?
Your best course of action depends on where you are in your contract. Find your situation below.
6–12 months before contract end
Start comparing now. Locking in early protects against market price rises. No exit penalty at your current end date.
30–90 days before end (notice window)
Act immediately. This is your renewal window, compare and choose now. Check your contract for exact notice requirements.
Contract expiring within 30 days
Contact Switch urgently. Fast-turnaround renewals can often be arranged to prevent out-of-contract rollover.
Already on out-of-contract rates
Switch now, no exit fees on out-of-contract tariffs. Every day is costing your business more than necessary.
Mid-contract, 6+ months remaining
Diarise your renewal window. Start comparing 3–6 months before your end date. Switch can alert you automatically.
Locked in via rollover clause
Check exit terms. In some cases, exit fees cost less than staying on a bad deal. We can help calculate the break-even.
How to Handle a Business Energy Contract Renewal: 5 Steps
Follow these steps at least 3 months before your contract end date to avoid rollover and secure the best available deal.
Find Your Contract End Date
On your energy bill, online account, or last renewal letter. Note the notice period (30–90 days). Microbusinesses: Ofgem rules now remove the need for advance notice at contract end.
Gather Your Usage Data
Business postcode, current supplier, annual kWh, MPAN/MPRN, and contract end date. Switch handles multi-site comparisons, contact our commercial team directly.
Compare the Full Market
Don't accept your supplier's renewal offer without comparing. Businesses that compare via Switch secure deals 10–25% cheaper than those who accept renewal offers without shopping around.
Choose Your Tariff and Confirm
Select the deal matching your budget. No cooling-off period on business contracts, compare carefully before confirming through Switch.
Submit Meter Readings on Changeover Date
Send readings to both old and new supplier for accurate billing. If a bill appears estimated, submit your actual reading and request a corrected invoice.
Which Type of Business Energy Contract Is Right at Renewal?
At renewal, UK businesses typically choose between a fixed-rate and a flexible contract. The right choice depends on your tolerance for price risk.
Fixed-Rate (12, 24, or 36 months)
Unit rate locked for full term. Best for businesses needing cost certainty for budgeting. Exit fees if leaving early. Protects from wholesale volatility.
Flexible / Variable
Rate moves with wholesale market. Best for businesses with cash reserves to absorb price changes. No cap on rate increases, harder to budget accurately.
Deemed / Out-of-Contract — Avoid
Supplier's default rate after a fix expires. Not a deal — a penalty rate. Unregulated, can increase without notice, costs 30–60% more. No business should stay here.
What to Compare Beyond the Headline Price
Six factors that determine your total annual cost. Switch displays all of them for every deal.
Unit Rate (p/kWh)
Core pricing metric. 1–2p/kWh difference equals hundreds to thousands of pounds at business volumes. Check electricity and gas separately.
Standing Charge (p/day)
Fixed daily charge regardless of consumption. Combined standing charges can add £300–£800/year. Lower standing charge benefits low-usage premises.
Contract Length
12, 24, or 36 months. Longer may offer lower rates but less flexibility. Balances price certainty vs optionality.
Exit Fees
Penalty for leaving before end date. May be per meter or a fixed lump sum. Can be £50–£500+ per contract.
Broker Commission (TPI)
Commission built into unit rates. Switch discloses this transparently on every deal. Can add 0.5–3p/kWh if undisclosed.
Green Certification (REGO)
Verify renewable tariffs are backed by REGO certificates. Low premium cost, high ESG and reputational value for your business.
