Capture Energy, Britain’s newest energy supplier, launches the UK’s first smart tariffs for business

Smart tariffs have already saved UK households billions of pounds. Capture is now bringing similar products to British businesses.

The need for smarter business tariffs is pressing because the UK has the highest industrial energy costs in the OECD. British businesses pay 50% more per unit of electricity than Germany and four times more than the United States.

How proven technology can offer British business free or discounted energy

Capture Energy aims to “help reindustrialise Britain,” says Co-Founder Clemens Munter, by optimising energy imports and exports at the best available prices. “Our data proves we can reduce an industrial electricity bill by 50% or more, or deliver a three-year payback on the purchase of batteries,” continues Munter.

The three new tariffs work for UK businesses of all sizes. Capture’s initial focus is SMEs. In Q1 2026, the average electricity price for non-domestic small-to-medium businesses was 28.08p per kWh, including the Climate Change Levy, according to government figures.

By contrast, British residential battery owners and EV drivers already access discounted energy tariffs. Sometimes wholesale prices go negative and the UK grid gives energy away for free.

Until the launch of Capture Energy’s three pioneering tariffs, British businesses could not take advantage of the dynamic pricing and optimised grid trading that UK households currently profit from. “Capture has built the software to operate as a next generation electricity supplier from scratch,” says Co-Founder Johannes Pittgens. “We offer the same simple and appealing tariffs to businesses that residential consumers already enjoy.”

Capture Energy’s technology is proven. The company already optimises thousands of residential, commercial and industrial batteries across Britain from leading energy storage manufacturers like Fox ESS, Alpha, Growatt and Solax. Their easy-to-use platform has saved the average British battery owner over 20% from their annual energy bill, according to independently verified data.

British businesses can now take advantage of dips in wholesale prices

Pittgens explains that UK businesses never receive the cheapest energy rates. “Even when energy prices go negative, commerce and industry pay their fixed rate tariffs and cannot feel the pulse of the market.”

UK wholesale prices change every half-hour, or 336 times per week. Flat tariffs from legacy energy suppliers include a substantial buffer that negates any daily dips in electricity prices, which could be utilised by British businesses. “Wholesale prices move constantly, fixed tariffs pretend they do not, and businesses pay for the pretence,” continues Pittgens. “We pass the real price straight to companies of every size.”

Similarly, British businesses cannot export back to the grid using the peak price structure accessible to British households. “From 4pm to 7pm, when many businesses are closed, and the UK grid is desperate for electricity, factories or offices can only sell their excess capacity for pennies,” says Pittgens. “This compares to up to 30p per kWh for UK homes that get paid for exactly the same electricity. Businesses could be helping to balance the UK energy grid while making money.”

How Capture Energy’s three new tariffs can help cut business bills

Capture Energy’s three new tariffs, which are exclusively for business customers, aim to minimise commercial energy bills while leaving no value on the table.  

• PowerImport is open to any UK business, whatever its size, even those with no solar panels or batteries of their own. It connects businesses straight to the current wholesale electricity prices and encourages use at the best-value times of day through simple red, amber and green bands – on PowerImport, electricity in the cheapest green band would have been available from as little as 15p per kWh over the past 365 days.
• PowerExport serves businesses with solar PV. Power generated on site can be sold to the grid at peak wholesale rates, against the fixed 6-8p per kWh most businesses receive at present. The tariff automatically switches between self-consumption when prices are low and exporting when they are high.
• PowerTrade, a combined import and export tariff for businesses with battery storage, works like an in-house trading desk – automatically managing consumption while buying electricity in the troughs of the wholesale market and selling it back at the peaks.

Every new customer has their energy usage analysed by a Capture Energy engineer before the company’s AI model takes over day-to-day optimisation. A savings forecast, drawn up from historical consumption and actual energy prices, is presented in plain English ahead of sign-up.
