Why rollover contract charges can be expensive for UK businesses
Higher unit rates
Rollover tariffs are commonly priced above fixed deals. Even small differences in p/kWh add up quickly if you run equipment, refrigeration, heating, or extended opening hours.
Uncompetitive standing charges
Many businesses focus on unit rates and forget standing charges. On rollover, standing charges can be noticeably higher, impacting you even in quieter months.
Reduced control and clarity
Default arrangements can come with unclear renewal terms. Switching proactively gives you a fixed term, clearer bills, and fewer surprises around renewal.
What are business energy rollover contract charges?
A rollover is what can happen when your fixed business energy contract ends and you don’t agree a new deal in time. Depending on your supplier and the contract terms, you may be placed onto a default tariff where the unit rate and standing charge are higher than competitive fixed offers.
Common scenarios
- Auto-rollover: your supplier renews you onto a new contract unless you terminate within a notice window.
- Out-of-contract rates: you stay supplied, but on higher default prices until you agree a new tariff.
- Deemed contract: often applies when you move into new premises and begin using energy without setting up a formal contract.
What “charges” usually means
- Higher p/kWh electricity or gas rates
- Higher standing charge per day
- Potentially different billing terms (e.g., estimated reads if you don’t submit them)
- Less choice on contract length and pricing structure
To avoid paying more than you need to, focus on the timing: check your end date, understand your notice period, and have a switch lined up. Next: how to avoid rollover charges.
How to avoid rollover contract charges (practical steps)
- Find your contract end date and notice window. Check your contract, latest bill, or supplier portal. If unsure, call your supplier and ask for the contract end date and the termination notice period.
- Start comparing early. Many businesses begin comparing in advance of renewal so they can choose a tariff length that fits their budget and risk appetite.
- Give termination notice (if your contract requires it). Some contracts need notice in writing or by email within a specific window. Missing it can trigger an auto-renewal or leave you temporarily on higher rates.
- Confirm the new supply start date and meter details. Accurate meter information helps prevent billing issues that can keep you stuck on expensive out-of-contract pricing.
- Submit readings on the changeover date. This reduces the risk of estimated bills and disputes when you switch supplier.
Notice periods and renewal windows (what to check)
The biggest reason businesses land on rollover or more expensive default pricing is simply timing. Your supplier contract may include a termination notice period and a specific way you must give notice.
| What to check | Why it matters | Where to find it |
|---|---|---|
| Contract end date | Determines when your fixed prices stop and when rollover/out-of-contract terms may begin. | Contract pack, renewal letter/email, supplier portal, or your bill. |
| Termination notice window | Missing the window can cause an auto-renewal or delay switching. | Terms & conditions; sometimes stated on renewal communications. |
| How to give notice | Some suppliers require notice in writing or to a specific email address. | Your contract T&Cs or supplier support team. |
| Site/meter details | Incorrect details can cause delays, estimated billing, or objections that keep you paying higher rates. | Bills, meter serial number, MPAN (electric) / MPRN (gas), and address. |
Rollover vs fixed deal: how costs can add up (illustrative)
Actual prices vary by supplier, region, meter type and market conditions, but the pattern is consistent: higher unit rates and standing charges can materially increase your bill. The examples below are illustrative only to show why avoiding rollover matters.
| Example business | Situation | What increases on rollover | Why switching early helps |
|---|---|---|---|
| Small office | Electricity only, standard business hours | Unit rate and standing charge | Lock a fixed rate and avoid paying a premium while you “decide later”. |
| Café / takeaway | Electricity + gas, cooking and refrigeration | Higher p/kWh has a bigger impact due to consistent load | Choosing a competitive tariff can reduce exposure during busy seasons. |
| Workshop / light industrial | Higher consumption, equipment usage | Any uplift in unit rate is amplified by kWh volume | Whole-of-market comparison helps find pricing aligned to your demand profile. |

Common mistakes that trigger rollover charges (and how to fix them)
Mistake: waiting for the renewal letter
Some businesses only act once a renewal reminder arrives. By then, the best timing window may be tight.
Fix: Set a diary reminder well before the end date and start comparing early.
Mistake: missing the termination notice window
If your contract requires notice and you miss it, you can be auto-rolled or delayed.
Fix: Confirm the notice requirements and keep a record of how/when you gave notice.
Mistake: incorrect meter or address details
Errors in MPAN/MPRN, meter serial numbers or site address can slow switching and cause billing issues.
Fix: Use your latest bill to confirm details before requesting quotes.
Mistake: not submitting readings
Estimated reads can lead to disputes and unexpected charges around the switch date.
Fix: Take photos of the meter on the changeover date and submit readings promptly.
FAQs: business energy rollover contract charges
Is a rollover contract the same as a deemed contract?
Not always. “Deemed” commonly applies when you take responsibility for a site’s energy supply without agreeing a contract (e.g., moving into new premises). “Rollover” is often used when a fixed contract ends and a default arrangement applies. The practical outcome can be similar: higher prices and less control.
Can I switch business energy supplier if I’m on rollover/out-of-contract rates?
In many cases, yes. The key is to start quickly to reduce how long you remain on higher default rates. If there are any contract constraints, we’ll help you understand options while comparing available tariffs.
How early should I compare to avoid rollover charges?
Early enough to account for your termination notice period and any internal approvals (e.g., finance sign-off). If you’re unsure, start the comparison now and confirm your end date and notice window at the same time.
What information do I need to get accurate business energy quotes?
A business postcode and contact details are a good start. For the most accurate pricing, it helps to have your latest bill with meter details and (where possible) consumption information, plus your contract end date.
Will switching interrupt my supply?
No—business energy switching is administrative. The same gas pipes and electricity wires are used; only your supplier and tariff change.
Do standing charges matter as much as unit rates?
Yes. Standing charges affect your costs every day, regardless of usage. Comparing both standing charges and unit rates helps you avoid “cheap unit rate” deals that aren’t competitive overall.
