British Gas Tariffs: Compare the best prices & switch

Blue box containing gas flame and electricity bolt next to British Gas tariffs logo

British Gas tariffs have a reputation for being on the expensive side and news reports constantly tell us that energy prices are on the rise - but are the rumours really true? Are British gas customers getting ripped off? Let’s take a look at what it costs to get your energy from British Gas.


British Gas Tariffs and Prices

British Gas releases different tariffs every few weeks, just like most energy suppliers do, which makes it difficult to keep track of prices. In an effort to simplify energy tariffs for customers, the energy regulator Ofgem introduced new rules in 2014 so that energy providers can only offer a maximum of four main tariffs to new customers. However, it remains a challenge even for us at Selectra to decipher the real price of energy from British Gas.

We’ve done the hard work, pored over the small print and put together a guide to British Gas tariffs that will help you, the customer, make up your mind about whether to switch to the energy giant. The following are the British Gas tariffs for domestic customers. If you're looking for business energy tariffs, check out our guide to British Gas Business.

British Gas tariffs for existing customers

British Gas existing customers seem to get a raw deal. Maybe at first it seems like you’ve got a great tariff, but once the end date has passed, you automatically start paying the standard variable rates, which are usually the most expensive.

What is the British Gas standard tariff?

If you haven't updated your British Gas energy tariff within the past year, it's likely that you're paying the standard rates laid out below.

British Gas standard variable tariff
Cost type Gas Electricity
Unit rate (per kWh) 3.104p 16.960p
Standing charge (per day) 26.074p 23.716p
Estimated annual cost £467.61 £578.38
Total estimated dual fuel cost per year £1,045.99
Total estimated dual fuel cost per month £87.17
Calculations based on a medium-sized home in London with average consumption levels of energy.

For Economy 7 meters, the stardard electricity rates are as follows:

  • Electricity day rate: 20.002p per kWh
  • Electricity night rate: 9.239p per kWh
  • Electricity standing charge: 23.799p per day

The rates on the British Gas standard tariff are currently cheaper than those with any of its new fixed-rate plans. This is rare for the supplier, and it's likely a reaction to decrease in the standard rate price cap, which went into effect in October 2020.

How do I change my British Gas tariff?

If you're an existing customer on the British Gas standard tariff, it's easy to change your tariff. You can do so either through your online account or by calling British Gas. If you're in a contract with British Gas, you can switch to a different tariff (or supplier) within the last 49 days (or seven weeks) before the contract officially ends and you won't have to pay an exit fee.

Domestic British Gas tariffs for new customers

In addition to the standard tariff outlined above, British Gas also offers a selection of fixed-rate tariffs and a prepayment tariff. Let’s have a look at them all in detail.

Note that these British Gas tariffs are also available for current customers. However, you won't be able to switch unless your out of your contract (or within the last 49 days).

HomeEnergy Fix Nov 2021v3

This fixed price tariff is currently open to new customers and offers fixed prices on gas and electricity until 30 November 2021. On this tariff, 100% of the electricity you use will be offset through British Gas purchasing electricity from renewable sources to put back into the National Grid. It does so by buying either Guarantees of Origin certificates (GoOs) or Renewable Energy Guarantee of Origins certificates (REGOs).

HomeEnergy Fix Nov 2021v3 prices
Cost type Gas Electricity
Unit rate (per kWh) 3.104p 16.960p
Standing charge (per day) 29.362p 27.003p

  • Electricity day rate: 20.002p per kWh
  • Electricity night rate: 9.239p per kWh
  • Electricity standing charge: 27.086p per day

If you’re on this tariff and you want to switch to a different one before the end date, you will be charged an exit fee of £30 per fuel.

Green Future Nov 2021v3

Like the HomeEnergy Fix Nov 2021v3 prices tariff, British Gas will offset 100% of the electricity you use on this tariff. It will also match 6% of the gas you use with renewable sources, as well as support the growth of up to five trees (per fuel) for each year you are on this plan.

Green Future Nov 2021v3
Cost type Gas Electricity
Unit rate (per kWh) 3.104p 16.960p
Standing charge (per day) 34.293p 31.935p
Estimated annual cost £497.61 £608.39
Total estimated dual fuel cost per year £1,106
Total estimated dual fuel cost per month £92.17
Calculations based on a medium-sized home in London with average consumption levels of energy.

Below are the Economy 7 rates for electricity with this Green Future Nov 2021v3 tariff:

  • Electricity day rate: 20.002p per kWh
  • Electricity night rate: 9.239p per kWh
  • Electricity standing charge: 32.018p per day

Green Future Nov 2021v3 has an exit fee of £30 per fuel, so if you want to cancel your contract before 30 November 2021, and you have both gas and electricity supplied under this tariff, you will be charged £60 to end your deal.

Electric Drivers Nov 2021 - ideal for owners of electric vehicles

British Gas says that the idea behind this tariff is to help reduce energy bills for the owners of electric vehicles who need to charge their cars overnight. This makes sense, since the unit price of electricity on this tariff is lower for five hours at night (12 a.m. to 5 a.m.) than it is during the day. Gas prices, however, are the same no matter what time of day it is.

Electric Drivers Nov 2021 prices
Energy type Gas Electricity
Unit rate (per kWh) 3.186p Peak rate 20.001p
Off-peak rate 4.700p
Standing charge (per day) 25.216p 25.001p
Estimated annual cost £474.31 Not applicable - depends on peak/off-peak use
Calculations based on a medium-sized home in London with average consumption levels of energy.

This tariff is similar to an Economy 7 tariff, but there are a few differences. An obvious difference is that the cheaper electricity is available for only five hours rather than for seven hours. Fortunately with this tariff, you can get a much lower rate during these off-peak hours than you would with most Economy 7 tariffs.

Unlike with an Economy 7 tariff, you do not need an Economy 7 meter for this Electric Drivers Nov 2021 tariff. You must, however, have a smart meter. If you don’t already have a British Gas smart meter, the suppleir will install one for you for free. It can take up to eight weeks from requesting a smart meter to having it up and running.

Energy with Boiler Cover Dec 2021v3

This fixed-rate tariff guarantees your prices won't change until 31 December 2021. In addition to your energy, this tariff also includes the British Gas Boiler & Controls Breakdown Cover for 12 months. If you decide to cancel this tariff early, you will be charged an exit fee of £30 per fuel.

Energy with Boiler Cover Dec 2021v3
Cost type Gas Electricity
Unit rate (per kWh) 3.104p 16.960p
Standing charge (per day) 29.404p 27.044p
Estimated annual cost £479.77 £590.53
Total estimated dual fuel cost per year £1,070.30
Total estimated dual fuel cost per month £89.19
Calculations based on a medium-sized home in London with average consumption levels of energy.

Below, you'll find the Economy 7 rates for this British Gas tariff with boiler cover:

  • Electricity day rate: 20.002p per kWh
  • Electricity night rate: 9.239p per kWh
  • Electricity standing charge: 27.127p per day

Safeguard PAYG

The standard British Gas Pay As You Go tariff, also known as the Safeguard PAYG tariff, is available to both new and current customers who have prepayment meters.

Safeguard PAYG prices
Cost type Gas Electricity
Unit rate (per kWh) 2.975p 16.590p
Standing charge (per day) 36.191p 28.060p
Estimated annual cost £489.17 £583.54
Total estimated dual fuel cost per year £1,072.71
Total estimated dual fuel cost per month £89.39
Calculations based on a medium-sized home in London with average consumption levels of energy.

Economy 7 rates for this British Gas prepayment tariff are as follows:

  • Electricity day rate: 19.900p per kWh
  • Electricity night rate: 8.560p per kWh
  • Electricity standing charge: 28.150p per day

Rates on this tariff are variable, meaning they fluctuate with the wholesale cost of energy. This tariff does not have an exit fee, so you are free to change to a different tariff without being penalised if the rates change.

If you would prefer a prepayment tariff with a fixed rate (perhaps for some peace of mind), you will need to sign up with either EDF Energy or Nabuh Energy instead, as these are the only suppliers that currently offer fixed-rate tariffs for prepayment customers. This type of agreement would protect the cost of your gas and electricity from any price increases for the duration of the contract.

British Gas Business tariffs

There are some important differences between domestic and business energy. Firstly, businesses do not have the right to the 14 day cooling-off period that domestic customers have during the switch process, which allows them to change their minds and cancel their energy plan up to two weeks after agreeing to a new contract.

Business energy deals also tend to be for longer periods of time than domestic energy plans. Anywhere between one and five years is standard for British Gas business energy. If you move into business premises where British Gas is the existing supplier, you will automatically be put on what’s called the ‘deemed rate’ (the default rate), unless you contact British Gas to request one of their energy plans. The deemed rate will often be slighter higher than the other tariffs.

Small business

Small businesses have a choice of several options with British Gas. There are fixed price plans where the unit rate doesn’t change for one, two or three years, depending on the plan you sign up to.

There is also a rolling 30 day tariff, which is essentially a variable price plan where the unit rate and standing charge can go up or down. British Gas gives you 30 days’ notice of a price change. Similarly, if you want to switch you can do so if you give 30 days’ notice.

Unit rates depend on your annual consumption and, in the case of electricity, they also depend on whether you use peak or off-peak energy. Here is an indication of what you can expect to pay.

British Gas Variable price plans for businesses
Cost type Gas Electricity
Unit rate (per kWh) 6.51p - 12.09p 30.41p - 54.09p
Standing charge (per day) 65.37p - 164.02p 68.87p - 135.35p

Large enterprises

For large businesses and corporate organisations there are fixed and variable tariffs available with British Gas. However, due to the complexities involved in supplying energy to corporate customers, it is best to contact British Gas directly to get an energy quote for a large business.


Is British Gas cheap?

electricity bill

British Gas is certainly not the cheapest on the UK energy market and, judging from the customer reviews published on sites such as Trustpilot, there are plenty of people who are left dissatisfied with paying British Gas prices and putting up with below average customer service.

Compare British Gas prices

British Gas does not come out particularly well in a comparison of prices with its competitors. The other Big Six energy suppliers sometimes beat British Gas on price, and sometimes turn out to be more expensive. In general, though, smaller energy providers tend to be considerably cheaper.

While the British Gas standard variable tariff will cost an average household somewhere around £1,046 per year for gas and electricity together, other providers have tariffs that come in under £1000 over the course of a year.

It’s not difficult to find providers with both cheaper prices and better customer service! For help finding the best tariff check out our guide on how to compare prices or give us a call on 0203 966 4692.

British Gas Price increases

We often hear of British Gas price increases but we seldom hear of any reductions! The price rises are usually defended by Centrica, the company that owns British Gas, with the argument that increases in the wholesale price of energy are beyond their control.

Price changes in the news

In April 2018, British Gas came in for some vocal criticism from the Energy Minister Claire Perry, who expressed that the UK Government was “disappointed” by the “unjustified” increase of 5.5% in the standard variable tariff.

In October 2018 the British Gas standard variable tariff increased again, this time by 3.8%. Only six months later, up went the price again, this time by 10.5%. Yes, that’s right - on 1st April 2019 British Gas customers started paying even more for their standard variable tariff.

Luckily for British Gas customers, the price cap was lowered in October 2019, April 2020, and again in October 2020, thus driving British Gas standard rates further down. At £1,042, the price cap currently sits at its lowest level since it was introduced in January 2019.Even though British Gas prices may have decreased, there are still plenty of energy deals available with other providers that work out much cheaper than the price cap and British Gas.

British Gas tariffs and prices FAQs

Here are some questions people often ask about British Gas tariffs - and some answers!

What is the cheapest British Gas tariff?

At the moment, the cheapest British Gas tariff available is the standard tariff, which is not typically the case. This tariff usually tends to be the most expensive British Gas offer. Even though this standard tariff currently offers the cheapest rates, we would actually recommend selecting the HomeEnergy Fix Nov 2021v3 tariff. It will currently cost you about two pounds more per year, and your rates will be protected from any increases until November 2021.

How much is British Gas per kWh?

Energy price per kWh depends on which tariff you’re currently on [link back up to domestic tariffs]. In general, gas costs just above 3p per kWh and electricity costs between 16p and 20p per kWh.

Is British Gas putting their prices up?

In October, British Gas actually decreased it's prices for its standard tariff by 7%. This was a result of the fall in the energy price cap. Many other energy providers, especially those among the Big Six, were also forced to decrease their standard rates.

Is British Gas business cheaper than domestic?

British Gas business tariffs generally work out to be more expensive than domestic tariffs for a couple of reasons. Firstly, businesses pay a higher rate of VAT on their energy bills; 20% as opposed to the 5% that consumers pay. Additionally, businesses have an obligation to pay the Climate Change Levy, which is something that domestic customers don’t have to worry about.


British Gas tariffs review - the Selectra verdict

scale with pros and cons

It's baffling as to why British Gas continues to retain so much of the market share, but for now, they continue to do so with around 12 million domestic customers.

Those customers tend to want to stay with a name that they know, but there are plenty of great deals to be had for those who take the plunge and switch to a smaller provider. Reviews of British Gas customer service would suggest price isn’t the only reason to switch.

Comparing British Gas prices to the Ofgem energy price cap and to other energy providers, we can’t give British Gas more than one star out of a possible five for value for money.
