The businesses paying the highest electricity rates in the UK are not necessarily the smallest ones, they are the ones who have not compared recently. Businesses on deemed rates or out-of-contract rates are almost always paying far more than they should be. Here is what each one means and why you need to avoid them:
A deemed rate applies when your business starts using electricity at a premises without signing a
contract. This typically happens when you move into a new commercial building. The supplier has a
legal obligation to continue supplying you, but since there is no agreed deal in place, they
charge a much higher default rate, often two to three times more expensive than a negotiated
contract. If you are unsure whether you are on a deemed rate, use our guide to find out who your
business energy supplier is and contact us straight away.
Deemed rates are not negotiated. You have no say in the price. The only way to escape a deemed
rate is to actively compare business electricity suppliers and sign a new contract as quickly as
possible.
You are likely on a deemed rate if any of the following apply to your business:
An out-of-contract rate, sometimes called a rollover contract, kicks in when your fixed-term business electricity deal expires and you have not switched supplier or renewed. Your supplier simply continues supplying electricity but at a significantly higher rate. In some cases, you may also find yourself locked into a new contract term you did not actively agree to.
This is one of the most common and costly mistakes UK businesses make. Setting a reminder three to six months before your contract end date to compare business electricity prices is the single most effective way to avoid it. BBC Utilities sends proactive renewal alerts to all our customers so this never catches you off guard.

Understanding the different tariff types before you compare business electricity suppliers helps you make a more informed choice. For a full breakdown of all commercial energy tariff options, see our gas and electricity tariffs guide. Here is a summary of the main electricity tariff types:
With a fixed-rate tariff, your unit rate per kWh is locked in for the duration of the contract typically one to four years. The amount you pay per unit will not change regardless of what happens to wholesale market prices during that period. This is the most popular choice for UK businesses because it makes budgeting straightforward and protects you from sudden price spikes. If you want price certainty, a fixed-rate deal is almost always the right choice.
A variable-rate tariff means your unit rate moves up and down in line with the wholesale
energy market. Bills can fall when market prices drop but they can also rise sharply,
especially during winter or periods of energy market volatility, as UK businesses
experienced in 2021 and 2022. Variable tariffs suit businesses that are comfortable with
that uncertainty and want to benefit from lower market prices when they occur.
A rollover contract begins automatically when your fixed-term deal expires without renewal. Your supplier continues to supply electricity at a much higher rate and in some cases, you are automatically locked into a new contract term. Rollover contracts are designed to benefit the supplier, not your business. Always compare and switch before your contract ends. BBC Utilities alerts all customers three to six months before their deal expires to make sure this never happens.
Yes and the difference is more significant than many businesses realise. As shown in the official government data table above, very small businesses pay over 40p/kWh on average while extra-large businesses pay around 20p/kWh. There are clear reasons for this gap.
Larger businesses consume far more electricity, which means they carry more value as customers for suppliers. They are more likely to negotiate directly, to use energy brokers, and to qualify for bulk pricing. Medium and large businesses also tend to commit to longer contracts, which suppliers reward with lower rates.
Smaller businesses use comparatively less electricity making bulk discounts rare and are statistically less likely to shop around for better deals. This means they often end up paying the highest per-unit rate in the market. If you run a small business, comparing business electricity prices is not just something worth doing, it is the primary lever you have for controlling this cost.
Whether you run a single-site cafe, a mid-sized office, a warehouse, or a multi-site retail chain, BBC Utilities compares electricity rates across the full market for your specific size and usage.

Start comparing three to six months before your contract end date. This gives you the time to evaluate all options and switch to the best available deal without pressure. If you are within 49 days of your end date, you can switch at no cost no exit fees, no penalties. BBC Utilities monitors your contract dates and alerts you before this window opens so you never miss it.
Knowing your meter type matters when comparing business electricity. Standard and smart meters record usage in straightforward intervals. Half-hourly (HH) meters required for sites using more than 100,000 kWh per year record usage every 30 minutes and can unlock better-priced tariffs from certain suppliers. Find out more on our half-hourly meter guide to see if upgrading your meter could unlock better rates for your business.
Some UK energy suppliers offer lower combined rates when you take both gas and electricity from them. After comparing your electricity, it is well worth checking your business gas too. You may find the best combined deal saves more than the best individual electricity deal. Compare business gas prices for free with BBC Utilities today.
Even the cheapest electricity tariff is wasted if your business is using more energy than it needs to. A basic energy audit of your premises can reveal quick wins switching to LED lighting throughout the building, putting heating and air conditioning on a timer, ensuring equipment is turned off overnight, and improving insulation to reduce draughts. These changes add up to genuine annual savings on top of any tariff saving.
Energy reduction works best as a team effort. Encourage staff to shut down computers and screens at the end of the day rather than leaving them on standby. Remind them to turn off lights in empty rooms and to avoid unnecessary printing. Even small behavioural changes across a team of ten can reduce your electricity consumption meaningfully over the course of a year.
