British Gas Renewable Energy & Sustainability

British Gas Renewable Energy & Sustainability

British Gas is one of the largest energy providers in the UK. They serve millions of customers. The company often discusses its green energy plans. But how much of its energy is actually renewable? With energy costs rising and changes to the price cap, many households are interested. They want to understand where British Gas gets its electricity and gas. They also want to know how sustainable its energy choices truly are.

British Gas Energy Mix: How Renewable Is It?

The UK government asks all energy providers to share their fuel mix each year. The latest report for British Gas (2023-24) shows how this is broken down:

Energy Source British Gas (%) UK Average (%)
Renewable Energy 60% 59%
Nuclear 20% 16%
Gas 15% 19%
Coal 3% 4%
Other 2% 2%

Key points:

  • British Gas gets 60% of its electricity from renewable sources. This is a bit more than the UK average.
  • However, 40% of its energy comes from fossil fuels.
  • There are green tariffs available, but not every British Gas customer takes advantage of them.

How Green Are British Gas Tariffs?

British Gas offers fixed energy tariffs, variable tariffs, and standard variable tariffs. But, not all of these options are fully renewable. Here is a comparison of these tariffs:

Tariff Name Renewable Electricity (%) Carbon Offset Gas? Exit Fee?
Standard Variable Tariff 60% No No
Green Future Energy 100% (via REGO) 10% biogas Yes (£40)
Go Green Tariff 100% (via REGO) None Yes (£50)

What Are REGO Certificates?

Many energy providers, such as British Gas, use Renewable Energy Guarantees of Origin (REGO) certificates. These certificates prove that their energy plans are environmentally friendly. However:

  • REGOs do not mean that energy comes straight from renewable sources.
  • Some plans labelled “green” still rely on fossil fuels. REGOs help balance this.
  • British Gas does not have its own renewable energy assets. This is unlike suppliers such as Octopus Energy or EDF.

Customers who want a green supplier should look at their choices to find a better deal.

Cost of Green Tariffs vs. Standard Tariffs

The unit rate and daily standing charge for green tariffs might be more expensive than for standard variable tariffs. Below is a comparison of energy tariffs from British Gas:

Tariff Electricity Unit Rate (p/kWh) Gas Unit Rate (p/kWh) Daily Standing Charge (p/day)
Standard Variable Tariff 24.50p 6.24p 60.99p (elec) / 31.66p (gas)
Green Future Fixed Tariff 27.10p 7.20p 55.80p (elec) / 29.99p (gas)

Is It Worth Paying More for a Green Tariff?

  • A fixed tariff can provide you peace of mind because it locks in your rates.
  • Green tariffs may cost more, but they support renewable energy projects.
  • A standard variable tariff is connected to Ofgem’s price cap, which means it can be cheaper when wholesale prices fall.

Impact of Ofgem’s Price Cap on British Gas Energy Prices

The Ofgem price cap decides the most energy suppliers can charge for their default rates. The new price cap rates will begin on 1st April 2024.

Period Price Cap (£ per year) Unit Rate (Electricity, p/kWh) Unit Rate (Gas, p/kWh)
Jan – Mar 2024 £1,568 22.36p 5.89p
Apr – Jun 2024 £1,690 23.12p 6.10p
Jul – Sep 2024 £1,717 (latest predictions) 24.50p 6.24p

The amount you save depends on the electricity you use. Meter readings can help ensure that your energy bills are correct.

British Gas Smart Meters & Energy Efficiency

A smart meter helps you check your electricity usage. It can show you simple ways to lower your energy costs. Here are some benefits:

Automatic meter readings mean you will no longer receive estimated energy bills. You can check electricity energy consumption values in real-time. Using monthly Direct Debit can help you save money. Many suppliers offer cheaper rates if you pay by Direct Debit.

British Gas Energy Trust helps customers with low income who are struggling to pay their bills.

How to Switch & Save on British Gas Tariffs

If you want a cheaper fixed price plan, just follow these steps:

1. Compare Tariffs

  • Check the new fixed price tariffs and energy quotes online.
  • Look for the exact savings compared to your current tariff.

2. Check Standing Charges & Exit Fees

  • Some tariffs have a lower unit rate. But, they can have a higher daily standing charge.
  • If you are on a fixed tariff, you may need to pay an exit fee if you switch early.

3. Use a Smart Meter to Track Usage

  • If you have a credit meter, you can check your energy use right now.
  • Small changes to your heating or appliances can help lower your electricity usage.

4. Secure a Fixed Tariff if Rates Are Rising

  • If price cap predictions say energy prices are rising, consider getting a better deal.
  • Fixed energy tariffs can guard you against changes in the cost of wholesale energy.

FAQs About British Gas Renewable Energy & Sustainability

Is British Gas really a green energy supplier?

British Gas gets 60% of its electricity from renewable sources. However, this number comes from REGO certificates, not from actually investing in renewable energy generation.

Are British Gas green tariffs fully renewable?

Green tariffs are entirely renewable, but they only apply to electricity. They still rely on REGOs. This means that British Gas may not get all of its energy from renewable sources.

How does the price cap affect British Gas customers?

The Ofgem price cap is the maximum amount customers pay with a standard variable tariff. From 1st April, this cap is £1,717 for a typical UK household.
