Frequently Asked QuestionsWhat is the cheapest energy supplier for small businesses in the UK? Octopus Energy for Business is consistently among the cheapest and highest-rated small business energy suppliers in the UK in 2026, offering transparent pricing, 100% renewable electricity, and strong customer service. E.ON Next Business and Yu Energy are also competitive for SMEs. Do small businesses get a different energy price cap? No. The Ofgem energy price cap only applies to domestic households — small businesses are not protected by it. This makes it even more important for small businesses to actively compare and switch to fixed-rate contracts. Can a small business switch energy supplier easily? Yes. Small businesses can switch energy supplier at the end of their contract or during the renewal window (typically 90–120 days before expiry). Online comparison sites make the process straightforward — most switches complete within 2–6 weeks. What VAT rate do small businesses pay on energy? Most businesses pay 20% VAT on energy. However, small businesses using less than 33 kWh of electricity per day (approximately 12,000 kWh/year) or 145 kWh of gas per day may qualify for the reduced 5% VAT rate. Contact your supplier to check eligibility. Is a business energy contract different from a domestic one? Yes. Business energy contracts have no 14-day cooling-off period, are typically 12–36 months, require separate contracts for gas and electricity, are not subject to the Ofgem price cap, and have different VAT rates. Always read the full contract terms before signing. | |||||||||||||||||||||||||||||||||||
