What is a British Gas tariff?

A British Gas tariff is the pricing plan you are placed on for your gas and electricity supply. It determines your unit rates, standing charges and contract terms. Through Energy Plus you can compare multiple British Gas tariffs against other UK suppliers to find a plan that better fits your usage and budget.

Can I switch to a British Gas tariff through Energy Plus?

Yes. Energy Plus lets you compare British Gas tariffs with other leading UK energy suppliers and complete your switch online in a few minutes. You simply enter your postcode and current usage, then choose the British Gas tariff that offers the best value before completing a quick online application.

How do I know if a British Gas tariff will save me money?

Use the Energy Plus comparison tool to enter details of your current supplier, tariff and annual energy usage. We then calculate your estimated yearly cost on your existing deal and compare it directly with available British Gas tariffs, showing clearly how much you could save before you decide to switch.

Are there exit fees for leaving my current energy tariff?

Some fixed-rate tariffs include exit fees if you switch before the end of the contract. During the Energy Plus comparison process we highlight any exit fees on your current deal and factor them into your savings estimate so you can decide whether moving to a British Gas tariff is still worthwhile.

Does switching to a British Gas tariff affect my supply?

No. When you switch to a British Gas tariff through Energy Plus there is no interruption to your gas or electricity supply. The change is purely administrative: your new supplier takes over your account while your energy continues to be delivered through the existing network.

How long does it take to switch to a British Gas tariff?

The online application via Energy Plus only takes a few minutes to complete. After that, most energy switches to a British Gas tariff complete within 5–21 days, depending on industry processes and whether you are in a cooling-off period. You will receive confirmation emails with your expected switch date.

Is my credit score affected if I switch to British Gas?

Energy suppliers, including British Gas, may run a credit check when you apply for certain tariffs, particularly fixed-rate or direct-debit plans. This is usually a soft or standard check and switching through Energy Plus does not in itself negatively affect your credit rating.

Can I choose a fixed or variable British Gas tariff?

Yes. Through Energy Plus you can compare both fixed-rate and variable British Gas tariffs. Fixed tariffs give you price certainty for a set period, while variable tariffs can move up or down with wholesale energy prices. Our comparison results clearly label whether a British Gas tariff is fixed or variable so you can pick the option that best suits your needs.

Types of British Gas tariffs available in the UK

British Gas offers a variety of tariffs to suit different households, budgets and usage patterns. Understanding how each works helps you choose the option that fits your home best.

1. Fixed-rate British Gas tariffs

Fixed tariffs lock in your unit rates (price per kWh) and often the standing charge for a set period (usually 12–24 months). Your monthly direct debit may still change if your usage changes, but the underlying rates stay the same for the term.

Protection from future price rises during the fix
Ideal if you want predictable pricing for budgeting
May include exit fees if you leave early

2. Variable-rate British Gas tariffs

Standard variable tariffs (SVTs) move up or down in line with wholesale energy costs and the Ofgem price cap. Your rates can change, usually with notice, which means bills may rise or fall over time.

Usually no exit fees, more flexibility
Rates can go down as well as up
Often the default tariff if your fix ends and you don't switch

3. Dual fuel tariffs

A dual fuel tariff means British Gas supplies both your gas and electricity under one plan. This can simplify bills and sometimes unlock dual fuel discounts compared to separate suppliers.

4. Smart meter & time-of-use tariffs

With a British Gas smart meter, you may be able to access smart tariffs or time-of-use pricing, where you pay different unit rates at different times of day. These can reward you for shifting usage away from peak periods.

Energy Plus shows which British Gas tariffs are compatible with smart meters or offer special rates, so you can see if they fit your lifestyle.

Typical British Gas tariff features

Electricity unit rate (pence per kWh)
Gas unit rate (pence per kWh)
Daily standing charge for each fuel
Contract length (e.g. 12, 24 months)
Exit fees on some fixed tariffs
Online account and app management
Paperless billing discounts on some plans

Exact prices vary by region, meter type and usage. Use your bill or smart meter data for the most accurate comparison.

How British Gas tariff pricing works

Your energy bill is mainly driven by two elements on your British Gas tariff: the unit rate and the standing charge.

Unit rate (per kWh)

This is the price you pay for each kilowatt hour of gas or electricity you use. The more you use, the higher this part of your bill. Fixed tariffs lock this in; variable tariffs can change in line with the market and the Ofgem price cap.

Standing charge (daily fee)

The standing charge is a daily cost that covers the maintenance of the energy network and keeping your home connected, regardless of how much you use. Some tariffs offer lower standing charges but higher unit rates, which may suit lower-usage households.

Energy Plus compares both the standing charge and unit rate across British Gas and other suppliers so you can see the true total cost for your typical annual usage.

What affects your British Gas tariff price?

Region: Energy distribution costs vary across UK regions.
Meter type: Standard, Economy 7, prepayment and smart meters all have different pricing structures.
Payment method: Direct debit is often cheaper than paying on receipt of bill or prepayment.
Usage level: High or low usage can influence which tariff is cheapest for you.
Tariff type: Fixed, variable or smart tariffs each have different rate structures.

The Ofgem price cap sets a maximum average price for standard variable and default tariffs, but you may still save by switching to a fixed or alternative British Gas tariff.

British Gas tariff FAQs

Answers to common questions about British Gas tariffs, prices and switching in the UK.

Is British Gas the cheapest energy supplier?

No single supplier is always the cheapest. British Gas can be competitive in some regions and tariff types, but the only way to know if it's cheapest for you is to compare your exact usage and postcode against multiple suppliers. That's what Energy Plus does for you in minutes.

Are British Gas tariffs covered by the Ofgem price cap?

Yes. British Gas standard variable and default tariffs are subject to the Ofgem price cap, which limits the average unit rate and standing charge for typical usage. Fixed tariffs are not capped in the same way, but they must still comply with Ofgem rules and consumer protections.

Will my gas or electricity be cut off when I switch?

No. When you switch to a new British Gas tariff – or from another supplier to British Gas – your gas and electricity supply will continue as normal. The changeover is handled automatically in the background between suppliers and the network.

Do British Gas fixed tariffs have exit fees?

Many fixed-rate British Gas tariffs include an exit fee if you leave before the end of the contract term, although the fee and conditions vary by tariff. Energy Plus clearly highlights any exit fees when you compare, so you know exactly what you're signing up to.

Can I get a British Gas tariff with a smart meter?

Yes. British Gas supports smart meters nationwide and offers smart-compatible tariffs. A smart meter sends automatic readings, so you receive more accurate bills and can track your energy usage more easily. Some smart tariffs offer cheaper off-peak rates.

What information do I need to compare British Gas tariffs?

To get the most accurate comparison, have your latest bill to hand. The key details are: your postcode, current supplier, tariff name, meter type and either annual kWh usage or monthly spend. But if you don't have these, Energy Plus can still provide an estimate using typical usage profiles.
