Uncovering The Latest Energy Efficiency Grants For Autumn 2026

Getting your Trinity Audio player ready...

Introduction

According to a 2026 report titled From Crisis to Stability: A Future Energy System for Manufacturers from Make UK, high industrial energy costs could cost the UK up to £85bn per year in economic output from reduced manufacturing activity. Manufacturers have warned that unless urgent action is taken on continued high energy costs for the duration of 2026 and beyond, a number of factories could end up facing closure.

Around 90% of manufacturers have seen energy bills increase since 2022 and over 50% cite high energy costs as their biggest business challenge. 13% have warned that further price increases could threaten their viability and 70% of manufacturing firms are passing higher costs onto their customers.

As a result of ongoing high energy pressures, around 75% of manufacturers view renewable led power as the route to cheaper energy, 71% have pledged net zero as important to their operations and 87% would invest more money in decarbonisation activities if electric costs were reduced.

There are a number of Government backed fully funded energy audits available for businesses in the UK to help advise them on the best course of action to improve energy efficiency, reduce energy usage and lower their carbon footprint. Recommended energy efficiency improvements from these audits can then be partially or fully funded by grants and loans. Funding and energy audits are typically administered to businesses by providers in their local areas, such as councils, business enterprise support organisations and industry specialists. Eligible costs for grants and loans can include the purchase of green capital equipment, renewable energy options, access to clean transportation and energy efficient building materials and infrastructure.
