How do I switch my business gas and electricity supplier in the UK?

To switch your business gas and electricity supplier in the UK, start by comparing tariffs based on your current usage, contract end date and meter details. Once you have chosen a better deal, your new supplier will handle the switch, including contacting your existing provider and arranging the transfer date. There is usually no interruption to your supply and no need for any physical work on your premises.

Will my business energy supply be interrupted when I switch?

No, your business gas and electricity supply will not be interrupted when you switch supplier. The change is purely administrative and takes place in the background over the existing network. Your meters, cables and pipes stay exactly the same, so your business continues to receive energy as normal throughout the switching process.

How long does it take to switch business energy supplier?

Most business energy switches take between 4 and 6 weeks from the point you agree a new contract, although some switches can complete faster depending on your current supplier, contract terms and meter set-up. Providing accurate meter readings and contract information up front helps to avoid delays.

Can I switch business gas and electricity if I am still in contract?

You can normally arrange a new business energy deal shortly before your current contract end date, but if you switch too early you may face early termination fees. Check your contract for the notice period and renewal window. In many cases you can lock in a new tariff several months before your existing contract ends, with the new prices starting on your agreed switch date.

What information do I need to switch my business energy supplier?

To switch business energy supplier you will usually need your latest gas and electricity bills, your business name and address, the name of your current supplier, your contract end dates, and your meter numbers (MPAN for electricity and MPRN for gas). Having recent meter readings and an estimate of your annual consumption will help you secure the most accurate quotes.

Can I combine my business gas and electricity with one supplier?

Yes, many UK energy providers offer dual fuel contracts that combine business gas and electricity with a single supplier. This can simplify your billing and account management, and in some cases may provide access to more competitive bundled rates compared with arranging separate contracts.

How much could my business save by switching energy supplier?

The amount your business could save by switching energy supplier depends on your current tariff, energy usage, contract terms and location. Many businesses reduce their gas and electricity costs by comparing the market at renewal rather than rolling onto out-of-contract or default rates. Reviewing your contract regularly and switching to a more competitive deal can lead to significant annual savings.

Is there any downtime or engineering work needed when I switch?

No, there is normally no downtime or engineering work required when you switch business gas and electricity supplier. The physical infrastructure remains the same and the only change is the company that bills you and manages your contract. You may be asked to provide an opening meter reading on the switch date so both suppliers can issue accurate final and opening bills.

Can I switch if my business has multiple sites or meters?

Yes, businesses with multiple sites or meters can switch suppliers and may be able to consolidate their contracts for easier management. Many business energy providers offer multi-site or group contracts that bring several locations under one agreement, with aligned end dates and a single point of contact for billing and support.

What happens after I agree a new business energy contract?

After you agree a new business energy contract, your new supplier will confirm your tariff, contract length and start date. They will contact your current supplier to arrange the transfer and handle all of the switching administration. You simply continue using energy as normal, provide any requested meter readings and check your final and first bills to ensure the details match your agreed terms.

Home Energy Tariffs Explained

Understanding the different types of home gas and electricity tariffs helps you choose the right deal for your household. Here are some of the most common options you'll come across when you compare suppliers.

Fixed-Rate Home Energy Tariffs

With a fixed-rate tariff, the unit price you pay for gas and electricity is locked in for a set contract period, usually 12, 24 or 36 months.

Protection from price rises during your fixed term
Easier to budget for your monthly bills
May include exit fees if you leave before the contract ends

Variable Home Energy Tariffs

On a variable tariff, your unit rates can go up or down, often in line with wholesale energy prices or price cap changes.

You may benefit when prices fall
More flexibility, often without exit fees
Bills can increase when market prices rise

Dual Fuel Tariffs

A dual fuel tariff means you get both your gas and electricity from the same supplier under a single plan.

One supplier and often one combined bill
Some suppliers offer dual fuel discounts
Convenient if you prefer dealing with a single provider

Green & Renewable Tariffs

Green tariffs support renewable electricity generation, and some include carbon-offset gas options.

Electricity backed by Renewable Energy Guarantees of Origin (REGO)
Helps reduce your home's carbon footprint
Options range from partially to 100% renewable

Tips to Save Even More on Home Energy

Switching to a cheaper tariff is one of the biggest ways to cut your gas and electricity bills, but there are other simple steps that can help reduce your overall usage too.

Use Smart Meters

Smart meters and in-home displays show real-time usage, helping you understand where you can cut back.

Improve Insulation

Loft and wall insulation, draught-proofing and efficient windows keep heat in and reduce gas consumption.

Upgrade Appliances

Replacing old, inefficient appliances with modern A-rated models can lower your electricity use.

Optimise Heating

Lowering your thermostat by just 1°C and using smart heating controls can make a noticeable difference to your gas bill.

Frequently Asked Questions About Switching Home Energy

Find answers to common questions about changing your home gas and electricity supplier in the UK.

No. Your gas and electricity are delivered through the same pipes and cables regardless of who bills you. When you switch home energy supplier, there is no physical change to the supply, so you should not experience any interruption.

Once you confirm your new tariff, most domestic energy switches in Great Britain complete within 5 working days under the Energy Switch Guarantee, although some may take a little longer. You'll normally have a 14-day cooling-off period from the date you sign up to your new tariff.

In most cases you don't need to speak to your existing supplier to start the switch. Your new supplier will contact them on your behalf. You may receive a final bill, and if you're in credit you should receive a refund once your old account is closed.

You can usually switch before your fixed term ends, but you may need to pay an exit fee. Check the terms of your current tariff or your latest bill. Sometimes it still makes financial sense to switch even with an exit fee, especially if prices have fallen or your current deal is no longer competitive.

If you're responsible for paying the gas and electricity bills directly, you usually have the right to choose your own home energy supplier. If your landlord includes energy within your rent, they will typically control the tariff, but you can still discuss the benefits of switching with them.

Some suppliers may carry out a credit check, particularly for direct debit tariffs. If you have a limited credit history or previous issues, there are still options available such as prepayment meters or tariffs where you pay on receipt of bill. We can help you understand which deals are most suitable for your circumstances.
