How to find the best UK business energy tariffs

Then, use a trusted comparison service like EnergyCosts.co.uk to compare quotes from multiple suppliers side by side.

How business energy pricing works
Business energy prices work very differently to household energy bills. There is no price cap, contracts are individually priced, and costs can vary significantly between suppliers, locations and usage levels. Understanding how pricing is structured helps businesses make better decisions and avoid expensive rollover or deemed tariffs.
What makes up a business energy price?
A typical business electricity or gas price is made up of several components:
- Unit rate (pence per kWh) – the cost of each unit of energy you use
- Standing charge (pence per day) – a fixed daily fee to cover network and administration costs
- Wholesale energy costs – the market price suppliers pay for gas and electricity
- Network and distribution charges – fees for transporting energy to your premises
- Environmental and policy levies – charges supporting renewable energy and infrastructure
- Supplier margin – the profit margin added by the supplier
Because these elements fluctuate, two businesses with similar usage can still receive very different prices.
Why business energy prices differ from domestic tariffs
Unlike household energy, business tariffs are not protected by a government price cap. Suppliers assess risk differently for each contract, taking into account:
- Annual energy consumption
- Contract length
- Meter type (standard, smart or half-hourly)
- Payment method and credit risk
- Market conditions at the time of agreement
This is why comparing business energy prices regularly is essential — loyalty alone rarely guarantees the best deal.
Fixed vs variable business energy rates
Most UK businesses choose between two main pricing structures:
- Fixed-rate contracts lock in unit rates and standing charges for an agreed term, typically between 1 and 5 years. These offer budget certainty and protection against market price rises.
- Variable or flexible tariffs move in line with market prices. While they can fall when wholesale costs drop, they also expose businesses to sudden increases and are often more expensive long term.
For larger users, suppliers may offer bespoke or flexible purchasing contracts, allowing energy to be bought in stages rather than all at once.
What are deemed and rollover rates?
If a business moves premises or reaches the end of a contract without agreeing a new deal, it is placed on a deemed tariff by the supplier. These rates are usually significantly higher than negotiated contracts and can increase energy bills by thousands of pounds per year.
Similarly, rollover contracts automatically renew at uncompetitive rates unless action is taken before the contract end date. Reviewing prices early helps avoid both scenarios.
Why comparing suppliers can reduce costs
Because pricing is unregulated and highly competitive, suppliers frequently offer different rates for the same usage profile. Comparing suppliers allows businesses to:
- Access lower unit rates and standing charges
- Choose contract lengths that suit cash flow planning
- Switch to renewable or low-carbon tariffs
- Avoid costly out-of-contract pricing
EnergyCosts.co.uk helps UK businesses understand these pricing factors and compare suppliers based on real market conditions, not headline promises.
