UK Manufacturing Energy Costs: Outlook and Options

For UK manufacturing and engineering SMEs, energy is no longer a routine overhead. It is one of the largest variable costs on the P&L, one of the most exposed to policy and geopolitical shocks, and, in 2026, one of the hardest to plan around.

Wholesale gas and electricity prices are down from their 2022 peaks. The reduction in the underlying commodity price has not translated into a proportionate reduction in what businesses actually pay, because the non-commodity element of the bill (network charges, government levies, capacity payments) has been rising steadily and now accounts for the majority of a typical invoice.

This article covers where UK business energy costs sit in 2026, what is going up and what is coming down, the government support available to eligible manufacturers, and the practical routes a company can take now. We work with Eco Logic Partners, an independent energy brokerage and consultancy, to help our manufacturing and engineering clients get to grips with all of the above.

Who this applies to

The commentary below is aimed at:

• UK manufacturing and engineering SMEs with a meaningful electricity or gas load.
• Owner-managers reviewing operating costs for 2026-27 and beyond.
• Finance directors and CFOs modelling utility spend for the year ahead.
• Companies coming out of a fixed-price contract signed at the peak of the 2022-23 energy crisis.
• Energy-intensive businesses considering whether they may qualify for the British Industry Supercharger or the incoming British Industrial Competitiveness Scheme.

Where UK business energy costs sit in 2026

Recent data from Department for Energy Security and Net Zero (DESNZ) quarterly energy prices and Ofgem data show that an average UK SME is paying roughly 22p to 25p per kWh for electricity in 2026, with average standing charges in the region of 60p per day. Half-hourly industrial users on larger contracts see unit rates closer to 17p to 20p, but with much higher fixed daily charges.

In cash terms, an average UK business electricity bill in 2026 is roughly £1,200 a year for a micro business (5,000 kWh), £3,400 to £17,800 for a typical SME (15,000 to 75,000 kWh) and £42,000 to £75,000 for a heavier user (200,000 to 300,000 kWh). Manufacturing and engineering firms with production plant, machining, cold stores or coating lines can sit materially above these ranges.

In real terms, the position is that business electricity in 2026 remains around 75% above pre-2021 levels. Unlike households, who benefit from the Ofgem default tariff cap, businesses have no equivalent protection and are wholly exposed to the market.

The gloomy view: what is still going up

Three drivers are keeping the bill high even as wholesale prices ease:

Non-commodity costs

Transmission Network Use of System (TNUoS), Distribution Use of System (DUoS), Balancing Services Use of System (BSUoS), the Capacity Market, and green levies such as the Renewables Obligation and Contracts for Difference now account for roughly 60% to 65% of a typical business electricity bill. These charges are rising 4% to 7% a year as grid investment accelerates, and are largely outside the reach of a supplier switch.

Grid infrastructure investment

Ofgem has approved significant grid upgrade spending to accommodate renewable generation and the growth of EV and heat pump load. That investment is funded through network charges on the bill.

Geopolitical and weather risk

The UK remains a large importer of gas and LNG. Reduced Qatari LNG cargoes, Norwegian pipeline maintenance, and the permanent loss of Russian pipeline gas keep wholesale prices sensitive to Northern Hemisphere winter demand and to any supply-side event.

The positive view: what is coming down (or should be)

Not all of the picture is negative. Three points on the other side of the ledger:

Wholesale prices are off the peak

UK wholesale electricity is trading around 9p to 10p per kWh in the front of the curve in mid-2026, well below the 2022 peak. Forward contracts for 2027 delivery are trading around 9p, and 2028 delivery around 8p, suggesting a gradual downward trend if the geopolitical outlook holds.

Expanded government support for energy-intensive industries

The British Industry Supercharger (BIS) reduces electricity costs for around 586 eligible UK energy-intensive businesses. From 1 April 2026, the Network Charging Compensation uplift provides 90% compensation on eligible network charges, cutting an eligible business's electricity bill by around £65 to £87 per megawatt-hour in total.

The government is also consulting on the British Industrial Competitiveness Scheme (BICS), which is designed to expand relief to more than 7,000 energy-intensive manufacturers from 2027. Foundational sectors including steel, ceramics, glass, chemicals, automotive and aerospace are directly in scope. Engineering SMEs in adjacent supply chains may become eligible depending on the final rules.

Renewable and on-site generation options are maturing

Behind-the-meter solar PV, on-site battery storage, and Power Purchase Agreements (PPAs) are more accessible to UK SMEs than they were three years ago, both technically and commercially. Where a manufacturer has roof space, land, or a load profile that suits PPA structuring, these options can meaningfully reduce grid-imported volumes.

Typical bill breakdown: 2021 vs 2026

A comparison of a typical UK SME electricity bill by category, before and after the crisis:

Bill component	Share of bill, 2021	Share of bill, 2026
Wholesale commodity (electricity itself)	Around 45%	Around 30%
Network charges (TNUoS, DUoS, BSUoS)	Around 20%	Around 30%
Green levies (RO, CfD, FIT, CCL)	Around 15%	Around 20%
Capacity Market and other	Around 5%	Around 10%
Supplier margin, operating and metering costs	Around 15%	Around 10%
Total non-commodity share	Around 55%	Around 70%

The direction of travel is clear: an ever larger share of a business energy bill is set by policy and grid investment rather than by the underlying commodity price. This is why simply switching supplier, while still worth doing, no longer moves the total the way it once did.

Worked example

A UK precision engineering SME uses 300,000 kWh of electricity per year across a machining and heat treatment operation. Current all-in unit rate: 22p per kWh. Annual electricity spend: £66,000.

• Wholesale commodity element (roughly 30%): £19,800. Some room to move via a well-timed supplier tender or fix-and-flex product.
• Network and levy element (roughly 60%): £39,600. Largely fixed by policy, but a proportion can be reduced through on-site generation, demand-side response, or eligibility for the British Industry Supercharger where the sector qualifies.
• Supplier margin and metering (roughly 10%): £6,600. The most immediately negotiable element on contract renewal.

A well-managed procurement process, combined with a targeted efficiency review, will typically reduce the total bill by 5% to 15%. On a £66,000 annual spend, that is £3,300 to £9,900 a year, before any consideration of on-site generation.

Practical routes to reduce your energy cost

Broadly, there are five routes available to a UK manufacturing or engineering SME:

• Contract review and tender. A structured tender across the full panel of UK business energy suppliers, timed to the market rather than to renewal urgency, remains the biggest single lever on the commodity portion of the bill.
• Fix-and-flex products. For larger loads, a basket that combines a fixed base with a flexible element allows the business to capture wholesale price falls without carrying full market risk.
• Efficiency programme. Compressed air leaks, motor efficiency, lighting, heat recovery, and process controls typically deliver 5% to 15% consumption reduction with payback periods under three years.
• On-site generation and PPAs. Solar PV, on-site battery storage, and third-party PPAs can materially reduce grid-imported volume and hedge exposure to network charges.
• Government support eligibility. The British Industry Supercharger and the incoming British Industrial Competitiveness Scheme provide significant relief for eligible sectors. Checking whether your business qualifies is worth the time even if the answer is no.

We work with Eco Logic Partners, an independent energy brokerage and consultancy, to deliver the first three routes for our clients. Their model is straightforward: they review current supply contracts and usage, run a whole-of-market tender through their supplier relationships, and then work with the business on a reduction strategy tailored to the operation. Their advice on procurement is free at the point of use; efficiency and renewables projects are quoted separately.

Lexmore’s View

Lexmore Tax Advisory exists to help UK SMEs grow. In practice that means securing the tax reliefs our clients are entitled to (R&D Tax Relief, Patent Box, Employee Ownership Trusts, Capital Allowances) and bringing in trusted partners for the operational levers that sit outside the tax lane.

Energy is one of the most consequential of those levers for manufacturing and engineering SMEs. The wholesale relief that came after the 2022 peak has not fully translated to business bills, non-commodity costs continue to rise, and the government schemes that exist are eligibility-restricted and require an application. A well-run energy strategy typically delivers 5% to 15% off the current bill; a poorly-run one leaves that money on the table.

Our partnership with Eco Logic Partners gives our manufacturing and engineering clients access to specialist procurement and reduction expertise. If your R&D claim or your capital allowances position needs review at the same time, we can bring both conversations to the same table.

Clear commodity. Clear network. Clear strategy.
