Next update: when major broker or supplier notice-period practices for SME contracts change, or winter out-of-contract risk guidance is updated.
By: Switch Editorial Team, Switch Squid Ltd
As of 1 October 2026, the highest-leverage SME energy task before winter is finding your contract end date and notice window — not collecting another untitled “cheap unit rate” screenshot. Residential Ofgem caps (the £1,723 typical dual-fuel Direct Debit sketch) do not set your business rates. This guide is a contract-end playbook for UK small and medium sites. Links go to SwitchSquid’s business-energy hub only — never to residential comparison journeys.
Sources: public SME contract practice (fixed term, notice periods, out-of-contract / deemed rates) and SwitchSquid’s business-energy enquiry path. We may be paid when a business enquiry leads to a completed switch.
Start a business energy quote
- UK SME and commercial meters only — not household default tariffs
- Have contract end date, notice period, MPAN/MPRN and recent usage ready
- Main limitation: quotes need site details; results are not the residential £1,723 cap
Offer facts / process facts (checked 1 October 2026)
| Item | Detail | Why it matters in October |
|---|---|---|
| Residential cap sketch | £1,723 typical dual-fuel DD | Context only — does not price your SME site |
| First artefact to find | Contract end date + notice period | Missed notice can roll you into costly extensions |
| Usage pack | 12 months kWh + MPAN/MPRN | Brokers and suppliers cannot price blind |
| Enquiry path | SwitchSquid business-energy hub | Not MoneySuperMarket residential links |
October is when many fixed terms taken out one or two winters ago approach renewal. Diary the notice date now; pricing conversations are slower when half the market is chasing the same week.
How to find the contract end date without a scavenger hunt
Check the welcome pack PDF, the renewal letter, the online account “contracts” tab, and the broker portal if you used one. The end date and the notice period are different fields — a contract ending 28 February may need notice in January. If paperwork is missing, email the supplier’s business desk with the site address and MPAN/MPRN and ask for the current contract summary in writing.
Multi-site groups should build a one-page register: site, fuel, end date, notice days, broker, and whether half-hourly or non-half-hourly. Do not rely on memory across branches.
Why end-date discipline beats “cheap unit rate” screenshots
Out-of-contract and deemed rates can erase a winter of careful budgeting. A unit rate that looked sharp in a tweet rarely includes capacity charges, CCL treatment, broker fees or the shape of your half-hourly profile. Start from dates and usage; price second.
Business energy renewal checklist
- End date and notice period confirmed in writing
- 12-month usage export attached
- Decision maker available for Letter of Authority if using a broker
Fit summary
Good for: SMEs whose fixed term ends within the next 3–9 months and who need an orderly October planning pass.
Consider alternatives: if you are already out of contract, treat this as urgent recovery — gather usage and enquire immediately.
Not for: household dual-fuel switches under the £1,723 cap — use our residential energy guides instead.
Important conditions
- Business energy is not covered by the domestic price cap sketch.
- Notice periods and rollover clauses vary by supplier contract.
- Broker Letters of Authority should be time-limited and scoped.
- Half-hourly sites need richer data than a single annual kWh guess.
- Microbusiness rules differ from larger corporate tenders.
- VAT, CCL and climate-related levies can change the all-in pence.
Thirty-minute October playbook
1) Locate end date and notice period; put both in the calendar with a 14-day buffer.
2) Export 12 months of usage (half-hourly where relevant).
3) Note current standing / capacity charges and any pass-through items on the last invoice.
4) Confirm who can sign a Letter of Authority.
5) Start a SwitchSquid business-energy enquiry with site postcode, fuels and dates.
6) Compare all-in £ for the term — not a lone unit rate.
7) Diary the acceptance window so paperwork does not miss the notice cut-off.
Final decision card
End date inside 90 days → gather data this week and enquire now.
End date 4–9 months out → build the register and obtain indicative pricing before Christmas diaries fill.
Already out of contract → treat as priority; do not wait for a “perfect” tender pack.
Open the business energy hub
- Commercial enquiry path only
- Have dates and usage ready before you start
- Residential £1,723 cap links do not apply here
Worked shapes
Café on a two-year fix ending January: Notice may be due in December. Export usage now; do not wait for the first frost invoice.
Workshop with messy files: Ask the supplier for a contract summary while the meter operator data is pulled. Parallel tracks save a week.
Multi-site charity: Stagger renewals if possible so not every site hits the market in the same fortnight.

What to put in the renewal folder
Keep PDFs of the current contract, the last three invoices, any broker agreement, meter serials, and a photo of the meter cupboard label. When an analyst asks for “HH data”, you want a single folder, not a Slack archaeology project.
If ownership of the company changed mid-term, confirm the bill-payer legal entity still matches the contract before you sign a renewal — mismatches delay go-live.
How residential October noise distracts SMEs
Headlines about the £1,723 domestic cap are useful for staff households and useless as a business benchmark. Your site may see very different standing charges, availability fees and risk premia. Use domestic news as a calendar reminder that winter planning is due — then price the business meter on business data.
Directors sometimes delay because they hope wholesale charts will “calm down next month.” If your notice window closes first, the chart does not matter. Dates beat vibes.
Notice periods versus end dates — a worked calendar
Suppose a contract ends on 31 January 2027 with 30 days’ notice. The practical decision deadline is early January, not 31 January. Add internal approval time: finance sign-off, board cycle, or a trustee meeting for a charity. October 2026 is not too early to gather data for a January end date — it is often the only calm window before Christmas leave.
If notice is “not less than 90 days”, count backwards carefully and put two reminders in the diary: one for data collection and one for signature.
What “good” looks like in a quote pack
Ask for all-in estimated £ for the term, not only a unit rate. Clarify which charges are pass-through. Note whether broker commission is embedded. Check green certificates claims against what your policy actually needs. For half-hourly sites, confirm the quote used your real profile rather than a generic shape.
Reject pressure tactics that demand same-day signature without a written summary. Serious suppliers and brokers can usually hold a price for a short, stated validity window.
Microbusiness protections and still doing the basics
Microbusinesses have specific information and switching rules that differ from large corporate tenders. Those protections do not remove the need to know your end date. If a cold caller cannot tell you your current end date and only pushes a unit rate, slow down and verify through your own paperwork or a known enquiry path.
Keep a written note of every sales call: date, name, claimed savings, and whether they already hold a Letter of Authority. Revoke stale authorities when a broker relationship ends.
Winter operations while paperwork is in flight
Do not ignore site heating setpoints and LED upgrades while you wait for a renewal PDF — operational efficiency still cuts kWh. But efficiency is not a substitute for missing a notice window. Parallel the two workstreams: facilities reduce waste; procurement locks the contract dates.
FAQ
How do I find my business energy contract end date?
Check the contract PDF, renewal letter or online account. If missing, ask the supplier’s business desk for a written contract summary using your MPAN/MPRN.
Does the £1,723 October 2026 price cap apply to my SME?
No. That Ofgem sketch is for typical domestic Direct Debit dual-fuel customers. Business sites are priced differently.
What happens if I miss the notice period?
Many contracts roll onto extension or out-of-contract rates that can cost more. Diary notice early.
What documents do I need for a quote?
End date, notice period, site address, fuels, MPAN/MPRN and roughly 12 months of usage — half-hourly data if you have it.
Can I use residential comparison buttons for a shop or office?
No. Use SwitchSquid’s business-energy hub. Residential journeys are built for domestic accounts.
Should I wait until January to renew?
Only if your notice window allows it. If notice falls in autumn, start now even if the end date is mid-winter.
What is a Letter of Authority?
A document that lets a broker speak to suppliers on your behalf. Keep it time-limited and scoped to the fuels you want quoted.
Do you earn fees?
SwitchSquid may be paid when a business enquiry leads to a completed switch. Ask for a clear fee explanation before you appoint anyone.
