Your Business Energy Checklist for Winter 2026
Winter 2026 is shaping up to be one of the most challenging energy periods in recent memory. European gas storage levels have been running consistently 10 to 12 percentage points below last year throughout the injection season, Norwegian supply has been disrupted by a series of planned and unplanned maintenance events, and ongoing conflict in the Middle East has kept risk premiums firmly embedded in the forward curve. Wholesale gas and power prices have reached multi-year highs, with TTF breaking above €80/MWh and UK NBP surpassing 180p/th in early September.
For businesses, the message is simple: winter 2026 is not the time to be unprepared.
Whether you’re a manufacturer, a retailer, a hospitality operator or a facilities manager, the checklist below covers the key steps every business should take before the heating season arrives in earnest.
Procurement & contracts
- Check your contract end date immediately. If your energy contract expires before April 2027, you need to act now. Rolling onto a supplier’s out-of-contract rate in the current market could cost significantly more than a negotiated deal. Prices are high — but being on a deemed rate is almost always worse.
- Don’t wait for prices to fall before fixing. The forward curve remains elevated and backwardated, meaning near-term prices are at a premium to future contracts. Waiting for a significant price drop before acting is a high-risk strategy in the current environment. Speak to an energy consultant about your options.
- Consider a flexible procurement strategy. Rather than locking everything in at once, a multi-purchase approach allows you to fix portions of your consumption in tranches, reducing the risk of buying everything at a peak. This strategy requires active market monitoring — the kind of support an experienced energy consultant provides.
- Review contracts across all your sites. If you operate multiple sites, ensure you have full visibility of when each contract expires. Staggered renewals leave you exposed at different points and reduce your negotiating leverage. Aligning renewals where possible strengthens your position with suppliers.
Budget & forecasting
- Revise your energy budget for winter. If your energy budget was set earlier in the year, it almost certainly needs revisiting. Wholesale prices have risen sharply since the summer, and businesses that haven’t updated their forecasts may find themselves significantly short.
- Model a range of price scenarios. With geopolitical uncertainty still elevated and European storage at historically low levels, price volatility is likely to continue through the winter. Build high, medium and low price scenarios into your planning to understand your exposure.
- Account for non-commodity costs. Your energy bill is made up of more than just the commodity rate. Network charges, balancing charges, the Climate Change Levy and other levies can account for a significant proportion of your total cost — and they’re not always fixed. Make sure your budget reflects the full picture.
Bill management & supplier relationships
- Validate your energy invoices. Billing errors are more common than most businesses realise — incorrect unit rates, misread meters, wrong standing charges and misapplied levies all occur regularly. Check your invoices against your contracted terms and chase any discrepancies promptly.
- Ensure your meter readings are up to date. Estimated bills can cause significant problems at reconciliation, particularly in periods of high prices. Make sure your supplier has actual reads for all your meters and that half-hourly data is being collected correctly.
- Know who to contact when problems arise. With energy markets under pressure, supplier customer service queues lengthen. Ensure you have the right contacts at your supplier and consider whether having an energy consultant manage the relationship on your behalf would save you time and resolve issues faster.
Demand reduction & efficiency
- Audit your heating systems before winter. Boilers, heat pumps and HVAC systems that haven’t been serviced will run less efficiently and cost more to operate. Schedule maintenance now, before engineer availability tightens in October and November.
- Review your heating schedules and setpoints. Are your buildings being heated when they don’t need to be? Out-of-hours heating, over-heated storage areas and poorly configured building management systems are common sources of avoidable waste. A simple audit can identify quick savings.
- Shift energy-intensive processes where possible. If your operation allows for any flexibility, running energy-intensive processes during overnight or off-peak periods reduces your exposure to peak demand charges and can lower your commodity costs on flexible contracts.
- Check for compressed air leaks and insulation issues. These are perennial sources of energy waste in manufacturing and industrial settings. With energy prices at current levels, the financial case for fixing them has rarely been stronger.
- Ensure LED lighting is in place throughout your premises. If you still have fluorescent or halogen lighting anywhere in your business, switching to LED before winter will reduce your lighting costs immediately and improve conditions for staff during shorter daylight hours.
Renewables & on-site generation
- Review your on-site generation performance. If you have solar PV, check that panels are clean, inverters are functioning correctly, and generation data is being captured accurately. Solar output will be lower over winter, but maximising what you do generate reduces your grid dependency.
- Explore battery storage. Battery storage paired with on-site generation or charged from the grid at low-cost periods can reduce your peak demand and lower your overall energy costs. The economics are increasingly compelling, particularly with current price levels.
- Consider a Power Purchase Agreement (PPA). A PPA locks in a below-market electricity rate from a renewable generator, often with no upfront capital cost. With wholesale prices elevated, the savings available through a well-structured PPA are significant. An energy consultant can help you identify and negotiate the right arrangement.
Levies, taxes & compliance
- Check your Climate Change Levy (CCL) status. Businesses in eligible sectors may qualify for a significant CCL discount through a Climate Change Agreement (CCA). If you’re not in a CCA and operate in a qualifying sector, it’s worth exploring — the savings can be substantial.
- Verify your VAT rate. If your business qualifies as a de minimis user, or if you have mixed-use premises, you may be entitled to pay 5% VAT on your energy rather than 20%. Many businesses are overpaying without knowing it.
- Assess your eligibility for BICS. The Government’s British Industrial Competitiveness Scheme (BICS) is now open for applications, with the window running from 1 October to 30 November 2026. Eligible manufacturing businesses can receive exemptions from Renewables Obligation, Feed-in Tariff and Capacity Market levies — worth up to £40/MWh. If you haven’t already checked your eligibility, do so immediately.
Risk management
- Understand your price exposure. Do you know exactly how much of your energy consumption is fixed, and how much is floating? If you have any exposure to market prices — through flexible contracts, unhedged volumes or contract gaps — you need to understand the financial risk that represents at current price levels.
- Set price triggers for purchasing decisions. Rather than reacting to the market emotionally, agree a set of price levels in advance at which you will buy. This removes the guesswork and helps you act decisively when opportunities arise.
- Don’t leave contract gaps. A gap between your current contract end date and the start of a new one can mean days or weeks on expensive out-of-contract rates. Make sure you know your exact termination date and that your new contract starts before it.
Next Steps
Winter 2026 presents a genuinely difficult energy market environment — but businesses that plan, procure intelligently and manage their consumption actively will be far better placed than those that don’t.
The steps above don’t require significant capital investment. Most of them require time, attention and the right expertise. That’s where Cibus Energy comes in.
