Business Energy Tariffs
Not all business energy tariffs are the same. Understanding which contract type suits your business can make a significant difference to your bills. Ecosave compares tariff options from across the UK market so you get the right deal, not just any deal.
Fixed-Rate Business Energy Tariff
A fixed-rate business energy tariff locks in your unit rate and standing charge for the full contract term — typically 12, 24, or 36 months — regardless of wholesale market movements. This is the most widely used business energy contract in the UK and the tariff Ecosave most commonly recommends to businesses looking for cost certainty.
- ✓Complete price certainty for the duration of your contract
- ✓Protection against wholesale market spikes and energy price rises
- ✓Easier budgeting and financial forecasting across the year
- ✓Available from all major UK business energy suppliers
- ✓Contract lengths from 12 to 48 months to suit your business needs
Suitable for
Fixed-rate contracts suit any UK business — from sole traders and SMEs to multi-site retailers, hospitality groups, manufacturers, schools, and charities. If budget predictability matters to you, a fixed business energy tariff is the right choice.
Available suppliers
Pass-Through Business Energy Tariffs
Pass-through business energy tariffs — sometimes called transparent tariffs — separate wholesale energy costs from non-commodity charges (network charges, Climate Change Levy, balancing charges). You pay a fixed wholesale rate with all additional costs passed through at their actual values, rather than blended into a single unit rate.
- ✓Full transparency over every cost component on your bill
- ✓Potential savings when network and third-party charges fall
- ✓Suited to businesses with sophisticated energy management
- ✓Available from a range of UK commercial energy suppliers
Suitable for
Pass-through tariffs suit mid-size and large businesses, multi-site operators, and organisations with a dedicated energy or finance manager who wants complete cost visibility. Any business can request a pass-through business energy quote through Ecosave.
Flexible Business Energy Tariffs
Flexible business energy contracts — also known as tranche-buying or wholesale purchasing — allow you to buy your energy in portions from the wholesale market over time, rather than fixing your entire volume in one go. Managed by Ecosave's energy desk, flexible tariffs let you lock in tranches at advantageous market points throughout your contract period.
- ✓Ability to capitalise on dips in the wholesale energy market
- ✓Risk management through staged purchasing over time
- ✓Greater control over your average blended business energy rate
- ✓Supported throughout by Ecosave's energy procurement desk
Suitable for
Flexible energy contracts work best for high-consumption businesses with the appetite to manage market risk actively. Energy-intensive manufacturers, large hospitality groups, and businesses with a dedicated energy buyer benefit most — though Ecosave manages the procurement process on your behalf throughout.
Smart Export Guarantee (SEG) Tariffs
The Smart Export Guarantee (SEG) is a UK government-backed scheme enabling businesses with eligible small-scale renewable generation — such as rooftop solar panels — to earn money by exporting surplus electricity back to the National Grid. SEG export tariffs are offered by licensed UK electricity suppliers and can significantly reduce your net business energy costs.
- ✓Generate revenue from surplus renewable electricity you produce
- ✓Reduce your overall net business energy costs meaningfully
- ✓Supports the UK's net zero transition
- ✓No minimum export requirement for eligible technologies up to 5MW
- ✓Available from Yorkshire Gas & Power, British Gas, EDF, E.ON, TotalEnergies, and more
Suitable for
Any UK business with an eligible renewable generation system qualifies — including solar PV, wind, micro-hydro, micro-CHP, and anaerobic digestion up to 5MW. From office buildings and retail parks to farms and industrial sites, if you generate renewable electricity on-site, a SEG tariff can put money back into your business.
No Standing Charge Business Energy Tariffs
No standing charge business energy tariffs remove the fixed daily access charge from your energy bill, meaning you only pay for the units of energy you actually consume. While unit rates on these tariffs are typically higher than on standard contracts, they can deliver real savings for businesses with low or intermittent energy usage patterns.
- ✓Pay only for the energy you actually use — no fixed daily charge
- ✓Potentially lower total bills for low-usage or seasonal businesses
- ✓Simpler cost structure, especially across multiple low-use sites
- ✓Available on request through Ecosave
Suitable for
No standing charge tariffs suit seasonal businesses (holiday parks, event venues, agricultural sites), businesses with multiple low-usage premises, and any operation where energy demand is intermittent or unpredictable. They can also be a useful option for reducing fixed overheads where consumption is minimal.
Available suppliers
Renewable Business Energy Tariffs
Renewable business energy tariffs supply your business with electricity matched 100% to generation from renewable sources — including wind, solar, and hydro — certified by Renewable Energy Guarantees of Origin (REGOs). Ecosave compares green business energy tariff rates from across the UK market to find you the most competitive renewable deal available.
- ✓100% renewable electricity verified by REGO certificates
- ✓Strengthens your business ESG credentials and sustainability reporting
- ✓Supports the UK's transition to net zero carbon energy
- ✓Green business energy is now competitively priced against standard tariffs
- ✓Available from Yorkshire Gas & Power, EDF, E.ON, British Gas, TotalEnergies, Yu Energy, and more
Suitable for
Renewable business energy tariffs suit any UK business committed to reducing its environmental impact. From offices, retailers, and restaurants to schools, charities, manufacturers, and public sector organisations — if sustainability matters to you or your customers, switching to a green business energy tariff is an easy, impactful step.

Rollover / Default Business Energy Tariffs
A rollover or default business energy tariff is what your supplier automatically places you on when your fixed contract expires without renewal. Also known as deemed rates or out-of-contract rates, these tariffs are typically 2–5× more expensive than a negotiated fixed-rate business energy contract. Ecosave does not offer rollover tariffs — we help businesses escape them.
- ✓No long-term commitment — you can switch away at any time
- ⚠Note: out-of-contract rates are among the most expensive business energy tariffs available
- ⚠Many UK businesses remain on rollover rates for months or years without realising the cost
Suitable for
Rollover tariffs are not suitable for any business seeking value from their energy spend. If you are currently on a default or out-of-contract rate, switching to a fixed-rate business energy contract should be an immediate priority. Ecosave can compare alternatives and move you onto a competitive tariff within days.
Variable Rate Business Energy Tariffs
Variable rate business energy tariffs have no fixed unit rate — your business energy costs rise and fall in line with wholesale market movements and supplier pricing decisions. While they carry no exit fees, most businesses on variable tariffs are exposed to sudden, significant bill increases when energy markets spike, making financial planning difficult.
- ✓No exit fees — you can switch to a fixed-rate contract at any time
- ⚠Can offer lower costs during short periods of falling wholesale prices
- ⚠Note: prices can rise sharply and without warning — Ecosave recommends a fixed-rate business energy contract for most businesses
Suitable for
Variable tariffs are generally not recommended by Ecosave for businesses that need financial certainty. They may occasionally suit businesses on very short-term leases or in a period of transition who cannot commit to a fixed contract — though in most cases a short 12-month fixed-rate business energy contract offers better protection at a comparable or lower rate.
Is Your Business Energy Bill Higher Than It Should Be?
Thousands of UK businesses are unknowingly overpaying for business energy every month. Here are the most common causes.
Out-of-Contract Rates
When a business energy contract expires without renewal, suppliers automatically move you onto deemed rates — which can be 3–5× more expensive than a fixed tariff. Many businesses do not realise their contract has rolled over until bills spike.
Estimated Meter Readings
Suppliers often rely on estimated usage if a meter does not automatically send readings. This leads to paying for more energy than you used, or a sudden bill correction months later.
Hidden Standing Charge Increases
Even when your unit rate looks stable, suppliers may quietly increase standing charges, add admin fees, or apply pass-through charges without informing you. Over 80% of business owners never check these line items.
Wrong Business Category
If your business is incorrectly categorised by your supplier, you may be charged a higher commercial rate than necessary — for example, a small office billed at an industrial rate.
Incorrect Meter Setup
Billing errors from incorrect meter types are more common than you would think, especially during supplier switches. These errors can go unnoticed for months or even years.
Renewing at the Wrong Time
Renewing too close to your contract end date, or when wholesale prices are peaking, means less negotiating power and higher rates. Ecosave monitors wholesale prices daily and advises businesses on the best time to lock in.
Business Energy FAQs
Everything you need to know about business energy and how to switch business gas and power
How long does it take to switch business electricity?
Non-domestic switches usually take 5 business days to complete. You can compare and sign up for a new deal up to twelve months before your current deal ends. To avoid expensive rates, we advise arranging a new deal way in advance of your contract expiring.
Will switching interrupt my electricity supply?
No. Your current and new suppliers will work together to transfer your supply without any interruption. Your electricity will still be supplied through the existing cables, with no need for any physical changes to your premises.
What information do I need to switch?
We only need your business name and postcode to compare rates. The full switching process can be completed without any paperwork or meter readings. If you have a copy of your current bill, that can help us identify additional savings opportunities, but it's not required to get a quote or switch.
Do electricity prices vary by region?
Yes, prices vary based on supply and demand, supplier costs, and transportation costs in your region. Rural areas often have higher rates due to transportation costs.
Can I switch to green electricity?
Yes, green electricity options are available across most of the UK. Switching to renewable sources can benefit both your energy bills and your environmental image.
How can I reduce my business energy bills?
Switching supplier is often the single biggest saving. Ecosave offers free energy audits to identify the biggest savings opportunities specific to your business.
Why is my business energy bill so high?
The most common causes are being placed on expensive out-of-contract rates after your deal expires (these can be 3–5× your previous rate), estimated meter readings that do not reflect actual usage, hidden standing charge increases, and incorrect business categorisation. Ecosave can review your current bills, identify any overcharging, and help you switch to a lower rate — in some cases businesses recover money they have overpaid.
When should I renew my business energy contract?
Ideally 6–9 months before your current contract ends. Leaving it too late risks your account rolling onto out-of-contract or deemed rates, which can be 3–5× more expensive than a fixed tariff. Starting early gives you time to compare the market, negotiate, and lock in competitive rates. Ecosave tracks contract end dates for our customers and alerts them well in advance.
Should I fix my business energy rates?
For most businesses, a fixed-rate contract offers the best protection against price volatility. By locking in a rate for 12, 24, or 36 months, you get budget certainty and protection from market spikes. The right time to fix depends on where wholesale prices are heading — Ecosave monitors markets daily and will advise you on when to lock in and when to wait.
Why are UK business energy prices so high?
UK businesses pay some of the highest energy prices in Europe due to several factors: heavy reliance on imported gas, government levies like the Climate Change Levy, the cost of upgrading aging grid infrastructure, and exposure to global wholesale market volatility. When oil and gas prices spike globally, UK businesses feel it quickly. Working with a broker like Ecosave means we monitor markets daily and help you switch at the right time to minimise the impact on your bills.
