About British Gas Evolve

In this section, we’re going to run you through a few key questions surrounding British Gas Evolve, starting with the most basic one:

What is British Gas Evolve?

Originally called British Gas X, British Gas Evolve is a new arm of British Gas which offers 100% renewable energy and an energy account that is managed entirely online. Like other providers adopting a 100% online ethos, it does not offer customer support over the phone, instead directing customers to its online chat function.

Is it worth signing up for home energy with British Gas Evolve? We hope to help you decide this for yourself on this dedicated page.

What’s the difference between British Gas and British Gas Evolve?

British Gas Evolve operates independently from British Gas but is owned by the same company - Centrica. The main differences between the two are quite superficial. British Gas Evolve claims to offer 100% renewable tariffs and all of its customer service online, with no phone number to call if you need to speak with someone.

British Gas Evolve Reviews - is it any good?

Before signing up with a supplier, it’s important to know what it’s past and present customers think of it. To this end, we’ve gone in search of British Gas Evolve reviews online to see what we can dig up.

Unfortunately, a look at consumer review website Trustpilot does not paint a pleasant picture of what customers have to say about British Gas Evolve. It has an average rating of 2.1 out of 5 stars on the site, with two thirds of reviewers giving it the worst rating of 1 star. Unsurprisingly, difficulty contacting the provider is one of the main complaints from reviewers:

Sent umpteen messages as live chat does not work. Clearly overpaid these scammers and provided evidence yet just get fobbing off emails saying they don't understand. What a joke of a company.
Electricity bill and money

If there’s one thing we’ve learnt, it’s that customer service which only relies on live chat via the provider’s website or app only works if the live chat service is effective. British Gas Evolve reviews posted by past and present customers on Trustpilot suggest that this is not the case.

Another common issue reported by British Gas Evolve customers on the site is problems with bills. Many recent negative reviews report being overcharged, a problem which is usually compounded by not being able to get through to an agent to solve the problem.

While there is currently no data on British Gas Evolve, Citizens Advice data on British Gas bears these points out, the provider being rated just 2 out of 5 stars by its most recent report for both bill clarity and complaints.

British Gas Evolve Tariffs

British Gas Evolve prides itself on the simplicity of its offer, and as such has just two tariffs for you to choose from at the time of writing (last update: 09/08/2021). They are the following:

  • The Fixed One v4
  • The Green One v4

Both of these tariffs are fixed dual fuel tariffs, which means that the price you pay will remain the same regardless of the wholesale price of energy. There is, however, no exit fee when you decide to leave British Gas Evolve, which is unusual for fixed tariffs. Here is a more complete rundown of both deals:

Tariff name Tariff type Exit fee Fuel source
The Fixed One v4 Fixed (12 months) £0 ✅100% renewable electricity
❌Carbon neutral gas
The Green One v4 Fixed (12 months) £0 ✅100% renewable electricity
✅Carbon neutral gas

As you can see from our table, the only significant difference between the two tariffs is that The Green One, as well as the standard 100% renewable electricity, also comes with carbon neutral gas. This means that for every unit of gas you use, British Gas Evolve will engage in carbon offsetting activities to balance out the effect your use has on the environment.

We got a quote for the two tariffs and found that for the same usage The Green One was just a few pounds more per month than The Fixed One, so if you’re keen on doing your bit for the environment don’t think twice before choosing this tariff.

Fuel mix

Like all providers, British Gas Evolve is obliged to release data pertaining to its fuel mix annually. Let’s see exactly where their power is sourced from:

- Coal Natural gas Nuclear Renewables Other
British Gas Evolve average 0% 0% 0% 100% 0%
National average 5.2% 41.4% 18.7% 32.8% 1.9%

*Data is for the period from 1st April 2019 to 31st March 2020.

As you can see, British Gas Evolve’s tariffs are said to be run on 100% renewable electricity. British Gas produces a certain percentage of green electricity itself and makes up for the rest by engaging in purchasing REGO certificates.

It’s important to note that, though 100% of British Gas Evolve’s electricity is either green or offset, this is not necessarily true of your gas supply. Those on The Fixed One will receive their gas supply from the National Grid, which is generally natural gas - a fossil fuel. Those on The Green One receive the same natural gas but British Gas Evolve commits to offset every kWh of gas they use.

Warm home discount

British Gas Evolve does offer its customers the Warm Home Discount. The provider opens its application process for the Warm Home Discount scheme in early autumn, and its website offers you the ability to leave your phone number so that they will notify you when the window for applications opens.

The Warm Home Discount scheme is a one-off payment of £140 paid to those who are vulnerable to fuel poverty. There are two ways you could be eligible:

  1. Through the Core Group, if you receive the Guarantee Credit element of the Pension Credit.
  2. Through the Broader Group, if you’re on a low income and meet your provider’s criteria for eligibility.

Members of the Core Group need not apply for the discount - it is applied automatically to one of their bills during the winter months every year. Members of the Broader Group must apply every year and are not guaranteed to receive it even if they received it the previous year.

Don’t hang around!The Warm Home Discount is given out to members of the Broader Group on a first-come, first-served basis, so be sure to apply as soon as your supplier’s window for applications opens.

British Gas Evolve Login

As it is a 100% online provider with no telephone support, you would hope that British Gas Evolve would have an app for managing your account. Unfortunately, this is not the case. To manage your account, you’ll have to login via the website.

To access your account, you’ll need to go through the following steps:

  1. Giving them your email address. British Gas Evolve will send you email alerts when it's time for you to send meter readings, pay bills or for any other important updates about your account.
  2. Confirming a few details. There is a quick and easy process to confirm your identity.
  3. Creating a password. You'll need to set a password to secure your account online.

Once you’ve created your account, you can view and pay bills online, as well as submit meter readings and upgrade to a new deal if you fancy. For more information on your British Gas login, go to the Help & FAQs section of the provider’s website.

Smart meters

British Gas Evolve does not currently offer smart meters to its customers. If you already have a smart meter, you are able to switch to the provider but your meter will lose its smart capabilities and become a ‘dumb’ meter once you switch.

How do I contact British Gas Evolve?
