UK Industrial Electricity Prices: Why Solar Alone Won’t Fix It

This week’s call for the next UK Prime Minister to tackle industrial energy costs — from Make UK’s Stephen Phipson, reported by gasworld — names the real number: UK industrial electricity prices around 25.4p/kWh, against 15.6p/kWh in Germany and 17.6p/kWh in France. For manufacturers, warehouse operators and commercial landlords, that gap is not an abstraction. It’s the difference between a competitive cost base and one that pushes production overseas — which, per Make UK’s own research, a quarter of manufacturers are already considering.

Independent Solar Consultants works with exactly these businesses, and the instinct we see most often when a story like this lands is the same one: get a solar quote. It’s an understandable response to a real problem. It’s also, in isolation, the wrong first move.

Lets Interrogate the Narrative

The political response so far is narrow. From 2027, the British Industrial Competitiveness Scheme will reduce electricity costs by up to £40 per megawatt hour for over 7,000 electricity-intensive businesses in sectors like automotive, aerospace and chemicals, exempting them from levies including the Renewables Obligation and Capacity Market. Energy-intensive firms such as steel, chemicals and glass will also see their British Industry Supercharger network-charge discount rise from 60% to 90%.

That’s real relief — for a defined list of sectors, on a 2027 timeline. It says nothing for the mid-size food processor, the multi-let warehouse, the commercial landlord with a service charge full of energy cost pass-through, or the manufacturer one tier below “electricity-intensive” classification. Most of the businesses reading the coverage and feeling the pressure are not in scope of the scheme being discussed to fix it.

Independent analysis from the House of Lords Library confirms the UK has had the second-highest domestic electricity price in the G7, and Deloitte found the UK held the highest industrial electricity prices among 24 IEA member countries in 2023. This is not a one-year spike. It’s a structural cost position the UK has held for several years, and the scheme being proposed addresses a slice of it, not the whole of it.

What the Market Is Missing

The conversation about “industrial electricity prices” treats electricity as a single number — pence per kWh — when for most commercial sites the bill is made up of several layers: the unit rate, time-of-use bands, standing charges, and for larger sites, network demand (triad) charges that can dwarf the unit rate if a site runs heavy plant at the wrong half-hour of the wrong day.

A solar quote based on rooftop area and an estimated annual usage figure ignores almost all of that. It tells you how many panels fit on a roof. It does not tell you whether the site’s demand profile actually overlaps with daylight generation, whether the DNO connection has headroom to accept an export, or whether the single biggest saving available is actually a tariff restructure or a controls fix that costs a fraction of a solar install.

What Experience Shows

We’ve sat across the table from manufacturing clients who came to us already holding a solar quote, convinced it was the answer to a rising electricity bill. In more than one case, the half-hourly data told a different story: a site running three-shift production with its heaviest load overnight, when solar generates nothing. Sized correctly, solar still had a role — but as the third piece of a strategy, behind battery storage to shift cheap off-peak generation into the day shift, and behind a tariff renegotiation that alone cut more off the bill than the solar payback case assumed.

What clients consistently underestimate is how much the DNO connection — not the roof — constrains the project. A site can have perfect orientation and acres of usable roof and still be capped on export capacity by what the local network can accept. Sequencing that conversation after a solar contract is signed, rather than before, is the single most expensive mistake we see repeated across this sector.

A Moment That Stuck With Me

One project still sticks with me because it had nothing to do with solar panels.

I was asked to review the electricity costs for a manufacturing business after their bills had risen unexpectedly. As we worked backwards through the paperwork, we discovered what had happened.

Like many businesses, they had been contacted by multiple energy suppliers as their renewal date approached. Emails, phone calls and contracts were arriving almost daily. The member of the accounts team responsible for processing the renewal had been trying to keep on top of it all and, under pressure, signed the wrong agreement.

The contract carried a standing charge of around £2,500 per month. On a monthly electricity bill of roughly £6,000, almost half the cost wasn't the electricity itself—it was simply the privilege of having the supply.

By the time we became involved, the cooling-off period had long passed. The business was effectively locked into that agreement for the year.

What I remember most wasn't the numbers. It was the atmosphere in the room.

The managing director, the finance team and the accounts assistant all realised what had happened at the same moment. Nobody had acted carelessly; they had simply been overwhelmed by a procurement process that has become increasingly complex. Unfortunately, that one signature had real consequences. Costs had to be cut elsewhere, and even things like the staff Christmas party became part of the conversation.

It's a reminder that energy isn't just a line on a balance sheet. Decisions made under pressure ripple through a business, affecting investment, staff morale and ultimately competitiveness.

That's why I always encourage businesses to slow the process down. Before signing a renewal, before ordering solar panels, before investing in batteries, take the time to understand what you're actually paying for. The cheapest-looking quote and the quickest decision are rarely the same thing.

Industrial electricity prices matter, but so does every decision surrounding how a business buys, manages and uses that electricity. Getting the strategy right can be just as valuable as generating your own power.

The Commercial Logic

This isn’t an argument against solar. It’s an argument for sequence. The right order is need first, demand profile second, grid position third — equipment last.

Factor Typical Approach ISC Approach

Starting point Roof space and an installer’s quote Half-hourly demand data and load profile

Grid connection Assumed available, checked after signing DNO headroom checked before any commitment

Technology choice Solar by default Solar, battery, tariff, or controls — whichever fits the demand profile

Government schemes Assumed to apply broadly Eligibility checked against actual sector and scale

Outcome Underperforming system against an inflated payback case A strategy sized to the building and the bill it’s actually trying to fix

Global Context

The UK isn’t alone in treating high industrial power costs as a strategic risk. The UK government’s April 2026 package to decouple gas and electricity prices responds to the same root issue Germany and other European markets are wrestling with: that gas-fired generation, used roughly 60% of the time to set the wholesale price, drags the cost of cheaper renewable generation up with it. The pattern is consistent across developed energy markets — headline reform takes years to land, while the businesses paying the bill in the meantime are left to manage their own exposure.

The Right Questions

The question worth asking isn’t “should we buy solar.” It’s what the site actually needs, when it needs power, and what’s constraining the options before any technology gets chosen. A finance director weighing a six-figure energy investment should be asking for half-hourly consumption data before a single quote, for DNO headroom confirmation before a contract, and for a clear answer on whether the immediate saving is generation, storage, tariff, or simply running plant at a different time of day. Those questions cost nothing to ask and routinely change the answer.

High industrial electricity prices aren’t going away on a government timeline most businesses don’t qualify for. What changes the number on your bill is understanding what’s actually driving it — and that conversation should happen before any equipment gets specified, not after.

FROM JUSTIN’S DESK:

A scheme landing in 2027 doesn’t help the bill you’re paying this quarter.

I had a manufacturing client last year hold a solar quote like it was a lifeline. Roof was right, orientation was right, the numbers on the page looked good. Then we pulled the half-hourly data and found their heaviest draw was overnight — three-shift production, running hardest exactly when the sun isn’t out. Solar still had a place in their strategy. It just wasn’t first, and it wasn’t sized the way the original quote had it.

That’s the thing about a headline like “UK industrial electricity is among the most expensive in Europe.” It’s true. It’s also not actionable on its own. The fix isn’t a panel count, it’s understanding when your site actually pulls power, what your DNO connection will let you export, and whether the cheapest saving available is even generation at all — sometimes it’s a tariff you’re not on, or plant running at the wrong hour.

If I’m sat across the table from someone with a rising electricity bill, the first thing I’ll say is: don’t buy anything yet. Get the data. Then we’ll know what you actually need.

If your electricity bill’s been on your mind, I’m happy to have that conversation before you spend anything

FAQ

Q: Why are UK industrial electricity prices so high? A: UK industrial electricity sits around 25.4p/kWh, notably higher than Germany (15.6p/kWh) and France (17.6p/kWh), according to Make UK research reported via gasworld. Network charges, policy costs and the UK’s exposure to gas-set wholesale pricing all contribute. Independent Solar Consultants treats this as a structural cost issue, not a one-year spike.

Q: Does the British Industrial Competitiveness Scheme apply to my business? A: The scheme, launching from 2027, applies to roughly 7,000 electricity-intensive businesses in sectors including automotive, aerospace and chemicals. Most mid-size manufacturers, warehouse operators and commercial landlords fall outside its scope, which is why Independent Solar Consultants recommends assessing your own site’s options rather than waiting on eligibility.

Q: Will solar panels reduce my industrial electricity bill? A: Solar can reduce costs, but only if it’s sized against your actual demand profile rather than your roof space. A site with heavy overnight or shift-pattern demand may need battery storage or tariff restructuring before — or instead of — solar generation. ISC’s independent assessments start with half-hourly consumption data, not a panel quote.

Q: What should I check before buying a commercial solar system? A: Three things matter most: your half-hourly demand profile, your DNO connection headroom for any export, and whether your current tariff structure is even right for your usage pattern. Independent Solar Consultants checks all three before recommending any technology.

Q: How much does an independent commercial energy assessment cost? A: This varies by site size and scope. Independent Solar Consultants offers a starting consultation via the assessment page, with no obligation and no installer relationship influencing the recommendation.
