If you run a business in East Sussex, electricity is one of your biggest ongoing costs. Whether you are a builder, a shop owner, a restaurant, or a small office, that bill arrives every month without fail.
The honest truth is that most businesses in East Sussex are overpaying. Not because they chose the wrong supplier once, but because they never went back to check. Tariffs change, better deals appear, and businesses that do not compare end up stuck on out-of-date rates.
This guide will walk you through everything you need to know in plain language. What you are likely paying, what you could be paying, how to switch, and what to watch out for.
What Are the Current Business Electricity Rates in East Sussex?
Electricity rates for businesses are set nationally, so the prices below apply across East Sussex. What you pay per unit (pence per kWh) depends mainly on how much electricity your business uses each year; higher usage generally means a lower rate.
| Business Size | Yearly Usage | Avg. Rate (excl. tax) | Avg. Rate (incl. tax) |
|---|---|---|---|
| Very Small | 0 – 20 MWh | 40.64p / kWh | 41.15p / kWh |
| Small | 20 – 499 MWh | 27.57p / kWh | 28.27p / kWh |
| Small/Medium | 500 – 1,999 MWh | 27.23p / kWh | 27.81p / kWh |
| Medium | 2,000 – 19,999 MWh | 24.11p / kWh | 24.65p / kWh |
| Large | 20,000 – 69,999 MWh | 22.46p / kWh | 23.01p / kWh |
| Very Large | 70,000 – 150,000 MWh | 20.50p / kWh | 20.98p / kWh |
| UK Average | All sizes | 22.96p / kWh | 23.47p / kWh |
(Source: gov.uk )
The most striking thing in this table is the gap between the top and the bottom. A very small business pays around 40p per kWh while a large business can pay closer to 20p per kWh. That is twice the price for exactly the same electricity.
Small businesses pay more because they have less volume to negotiate with. But a comparison can still close that gap meaningfully and even saving a few pence per kWh adds up over a full year.
How Much Do East Sussex Businesses Spend on Energy Each Year?
Below is a breakdown of the estimated annual electricity and gas spend for businesses in East Sussex, split by business size. These figures are based on official ONS business counts and Ofgem consumption data.
| Business Size | Businesses | Electricity / yr | Gas / yr | Total / yr |
|---|---|---|---|---|
| Micro under 10 staff | ~22,500 | £90,725,040 | £32,994,000 | £123,719,040 |
| Small 10 to 49 staff | ~3,005 | £20,118,475 | £8,789,625 | £28,908,100 |
| Medium 49 to 250 staff | ~535 | £7,645,150 | £3,390,563 | £11,035,713 |
| Large 250+ staff | 45 | £1,285,875 | £658,125 | £1,944,000 |
| Total | 26,145 | £119,774,540 | £45,832,313 | £165,606,853 |
Micro and small businesses account for the vast majority of that total. Not because each small business uses a huge amount of electricity, but simply because there are so many of them over 22,500 micro businesses in East Sussex alone.

Which Type of Electricity Tariff Is Your East Sussex Business On?
Knowing your current tariff type is the first step to understanding whether you are overpaying. There are three main situations businesses find themselves in and each one has a different implication for your bill.
Fixed-Rate Contract
A fixed-rate contract locks your price per kWh for a set period usually one to three years. Your bill stays predictable regardless of what happens to the energy market. This is the most common type for businesses that have actively compared and switched.
The catch: once a fixed-rate contract expires, your business energy supplier will typically move you to an automatic renewal rate. This rate is rarely competitive. If your contract is ending soon, comparing before it expires is the single most effective action you can take.
Rollover Contract
A rollover contract is what happens when you do nothing at the end of a fixed deal. Your supplier automatically renews your contract but usually at a higher rate than you could get elsewhere. Many East Sussex businesses are unknowingly on rollover contracts right now.
The switching window: Most suppliers allow you to exit or renegotiate during a window that opens around 49 days before your contract end date. Miss that window and you could be locked in for another year at a poor rate. BBC Utilities tracks your end date and alerts you when the window opens.
Deemed Rate
A deemed rate is applied when there is no active contract in place for example, if you moved into a new premises and never set up an energy agreement, or if your contract expired without renewal.
Deemed rates are almost always the most expensive way to buy electricity. Suppliers are legally permitted to charge them, and some are significantly higher than what a comparable business would pay on a negotiated tariff. If you are on a deemed rate, switching should be urgent.
The Climate Change Levy - What It Is and Whether You Have to Pay It
The Climate Change Levy (CCL) is a government environmental tax charged on business energy use. It appears either as a separate line on your bill or built into your per-unit rate.
Most businesses pay it but there are exceptions. Some businesses qualify for a reduced rate or a full exemption, which can make a meaningful difference to their annual bill.
| Who Can Reduce or Avoid CCL? | Route to Exemption / Reduction | Potential Saving |
|---|---|---|
| Energy-intensive sectors (e.g. manufacturing, food production) | Sign a Climate Change Agreement (CCA) | Up to 92% off CCL on electricity |
| Businesses using certified renewable electricity | Levy Exemption Certificates (LECs) | Full CCL exemption possible |
| Charities and non-profit organisations | Apply for the 5% reduced VAT rate | Reduces overall energy tax exposure |

How Much Could Your East Sussex Business Save by Switching?
If every business in East Sussex reduced their electricity bill by 10%, the combined saving would be over £11.9 million a year. Here is what that looks like at an individual business level:
| Business Type | Estimated Annual Bill | 10% Saving | 20% Saving |
|---|---|---|---|
| Very small | £400 – £800 | £40 – £80 | £80 – £160 |
| Small (e.g. shop, café, small team) | £2,800 – £8,500 | £280 – £850 | £560 – £1,700 |
| Small to medium (e.g. restaurant, health clinic) | £14,000 – £55,000 | £1,400 – £5,500 | £2,800 – £11,000 |
| Medium (e.g. factory, hotel, larger office) | £50,000 – £500,000 | £5,000 – £50,000 | £10,000 – £100,000 |

Frequently Asked Questions
You can request a switch at any time, but if you are still inside a fixed-rate contract, your supplier may charge an exit fee. The best time to switch without any penalty is during your switching window which opens around 49 days before your contract end date. If you are currently on a deemed rate or a rollover contract, you can usually switch straight away with no exit fee.
Once you have agreed your new deal and signed up with the new supplier, the switch is usually completed within three weeks. Your electricity supply continues without interruption throughout.
No. The physical infrastructure, the wires, meters, and connections stays exactly the same. The only thing that changes is who bills you, and at what rate. Tens of thousands of UK businesses switch energy supplier every month without any disruption to their supply.
Four things: your business postcode, your current supplier name, your tariff end date, and your annual electricity usage in kWh. Everything you need is on your electricity bill.
