Why Do UK Businesses Need to Compare Energy Regularly?
5 Signs Your Business Should Compare Energy Today
If any of these sound familiar, your business is almost certainly overpaying.
Haven't compared in 12+ months
The commercial market changes every quarter. Deals that were expensive a year ago may now be competitive, and vice versa.
Contract within 6 months of expiry
The prime window to compare and lock in a fixed deal. Suppliers must notify microbusinesses 60 to 150 days before contract end.
Last bill was higher than expected
You may have silently rolled onto an out-of-contract rate, often 30 to 50% above the fixed deals available.
Standing charge has increased sharply
A rising trend in 2026 that unit rate comparisons miss. Some businesses see standing charges multiply at renewal.
Never formally compared before
Most first-time comparisons reveal significant savings immediately. The market rewards active comparison.
How Much Can Your Business Save?
Indicative savings ranges, not live SwitchSquid quotes. Commercial prices move with the wholesale market and there is no Ofgem price cap on business energy. For dated September 2026 unit rates see the snapshot below and our business electricity rates guide. All prices exclude 20% VAT unless you qualify for the reduced rate.

Business Energy Tariff Types: Which Is Right for You?
Choosing the right tariff structure can be just as important as choosing the right supplier.
Fixed Rate Tariff
Unit rate locked for 1 to 3 years. Protects from wholesale market volatility. Best for price certainty and budget planning.
Variable Rate Tariff
Rates move with the wholesale market. Can be cheaper when prices fall but exposes your business to sudden increases.
Flexible / Pass-Through
Hybrid structure, some costs fixed, others at wholesale. Best for medium-to-large businesses with energy manager oversight.
Green Business Energy
100% renewable electricity via REGO certificates. Competitively priced in 2026. Green gas (biomethane) also available from select suppliers.

Business Energy Standing Charges: A Critical 2026 Warning
Standing charges are rising sharply for commercial connections. Switch compares total annual cost: unit rate + standing charge + VAT.
TNUoS increases driving standing charge rises
Transmission network cost changes and unrecovered supplier failure costs are being absorbed into the fixed daily charge.
Some businesses seeing multiples of previous rates
A low headline unit rate can mask a dramatically higher total annual bill if the standing charge has surged at renewal.
Never choose a tariff on unit rate alone
Switch compares total annual cost, unit rate, standing charge, and VAT combined, so you see the full picture before committing.
Business Energy Protections UK Businesses Should Know
Key rights and protections for commercial energy customers.
No Interruption to Supply
When you switch, your energy supply is never cut off. Only the billing company changes. No engineer visits, no downtime.
Microbusiness Protections
Under 100,000 kWh electricity or 293,000 kWh gas per year? You qualify for 30-day switching rights, mandatory renewal notifications, and Ofgem ADR access.
Comparison Rights Without a Price Cap
No Ofgem cap on business energy, but commercial customers have the right to compare and switch freely. Switch exercises this right on your behalf.
Business Energy Comparison: How It Works
Know Where You Are in Your Contract
Most businesses overpay because a fixed contract ended and they rolled onto out-of-contract rates without noticing. Check your end date, then compare in your renewal window.
Electricity and gas can be compared separately or together, and some sites with low usage are better off on a no standing charge tariff.
