Are You on a Cheap Business
Electricity Tariff — or an
Expensive Rollover Rate?

When a business electricity contract ends, most suppliers roll customers onto a costly out-of-contract or deemed rate — often 25–35% higher than the cheapest available tariff. Many businesses stay on these rates for months without realising.

Win Energy compares business electricity rates per kWh from 30+ UK suppliers including cheap renewal tariffs, fixed-rate contracts, flexible plans and 100% renewable green electricity — all in one free independent comparison.

Cheap fixed-rate electricity — lock in a competitive unit rate for 1–3 years, protect against price rises

Flexible tariffs — benefit from wholesale price falls with a variable rate contract

100% green electricity — REGO-certified renewable energy, often at comparable prices to standard tariffs

Half-hourly metering — specialist HH electricity comparison for larger businesses

Multi-site contracts — one contract and one invoice across multiple UK locations

FAQ

Business Electricity Questions Answered

The cheapest business electricity tariff changes daily with wholesale prices. Win Energy compares live rates from 30+ UK suppliers so our comparison always reflects today's market — not a list that was updated last month. Contact us or WhatsApp for a real-time comparison for your business.
When your business electricity contract ends and you don't renew or switch, most suppliers automatically move you to an out-of-contract (also called 'deemed' or 'rollover') rate. These rates are typically 25–35% higher than the cheapest available fixed tariff. Win Energy can check if you're on one of these rates and switch you to a cheaper deal quickly.
Contact Win Energy before your contract end date — ideally 3–6 months before. We compare available renewal tariffs from 30+ suppliers and present you with the cheapest options. Many businesses who renew directly with their current supplier miss cheaper deals available elsewhere. Our comparison is free and takes minutes.
Half-hourly (HH) meters record your electricity consumption every 30 minutes. Businesses consuming over 100kW at peak demand are required by law to have HH metering. Win Energy specialises in HH electricity contracts — these require specialist suppliers and we compare the right panel for your profile.
Yes — REGO-certified 100% renewable electricity is available from multiple UK suppliers, often at similar prices to standard contracts. Win Energy includes green electricity options in every comparison so you can choose based on both cost and sustainability priorities.
Yes — completely free. We add a small agreed uplift to the base rate, which forms our commission — built into your unit price, just like any business builds its margin into its pricing. You are never invoiced by Win Energy. If your contract does not go live, we earn nothing.
