Welsh businesses to pay 13 per cent more in electricity bills than London

  Posted by: electime      2nd April 2025

Small and Medium sized Enterprises (SMEs)in North Wales and Merseyside, are forecast to pay 13 per cent more in electricity bills next financial year than their counterparts in London – equating to nearly £19,000 more in bills on an average like-for-like basis.

The data from Cornwall Insight’s Business Energy Cost Forecast predicts an average SME in the Wales and Merseyside region, such as a professional services business, or a medium sized office, will pay £161,000 a year for electricity costs, more than any other region in the country. Their costs sit at around 8 per cent higher than the predicted countrywide average of £148,000 a year, and 13 per cent higher than the capital at £142,000 a year.

The disparity in bills between the two regions, which is rising from the current 7.5 per cent, is due to North Wales and Merseyside having higher non-wholesale costs – also known as Third Party Charges (TPCs). The increasing gap will put more pressure on already struggling rural SMEs, particularly concerning after recent figures show unemployment in Wales remain 1 per cent higher than the UK average.

Third Party Charges differ from region to region. They include all electricity costs outside the price of the fuel itself- the wholesale price – and typically make up around 60 per cent of a business electricity bill. They are broadly split into network charges like distribution and transmission costs, and policy costs such as funding for government initiatives like renewable energy.

While policy costs are relatively uniform across the country, the regional variance is almost exclusively down to the level and structure of network charges between the areas, with these being set for each of the 14 regions of the British electricity market by regulated price control for each of the Distribution Network Operators (DNOs). These are dependent on a range of factors including terrain, population density and grid maintenance and upkeep costs, while transmission costs – as charged by the National Energy System Operator (NESO) on a regulated basis – also have regional differences.

While the government is consulting on the introduction of zonal wholesale pricing, it is important to remember that some costs are already locational.

Many SMEs, especially in rural areas, have seen profits fall over the past few years as inflation and rising costs take their toll on sales and eat into profit margins. A recent survey showed 72 per cent of UK businesses expect high energy prices to negatively impact profits over the next two years, and 81 per cent expect to raise prices in response to energy bills.

With many businesses’ electricity contracts up for renewal in April, numerous companies will be seeking to switch suppliers in hopes of securing better deals amidst the high costs.   

Dr Craig Lowrey, Principal Consultant at Cornwall Insight:

“These forecasts highlight the stark regional disparities in electricity costs for SMEs. Businesses are struggling with high energy costs across the country, but the steep third-party charges faced by those in particular regions only serves to highlight the problems faced by those businesses that could already be operating on razor-thin margins.

“As energy prices continue to weigh on businesses, it is crucial for SMEs to stay informed about their energy options. With many contracts up for renewal in April, now is the time for businesses to review their energy strategies, explore switching opportunities, and consider efficiency measures to help ease rising costs. Understanding the makeup of energy bills and engaging proactively with the market could be key to managing these financial pressures. With the government looking at the prospect of regional wholesale electricity costs as part of its market reform programme, it is clear that a holistic view of the energy costs faced by businesses is needed.”
