Cheapest UK Home Energy Suppliers & Tariffs – Autumn 2026

With more suppliers returning to the market and the Ofgem price cap updating every quarter, autumn 2026 is a key time to review your tariff. The cheapest supplier for your home will depend on your postcode, consumption and meter type, but there are clear patterns in the market.

Rather than chasing a brand name alone, focus on the cheapest total annual cost for the way you actually use energy. A supplier with slightly higher unit rates but a much lower standing charge can easily work out cheaper for lower-usage homes, and the reverse is true for energy-hungry households.

• Check both gas and electricity – dual fuel deals can be cheaper but not always.
• Compare fixed vs variable – a low fixed rate can protect you from future price rises.
• Look at the full year cost, not just the headline unit rate.
• Consider green tariffs – some are now priced close to or below standard tariffs.
