Home energy in 2025: what's changing?

Energy prices in the UK have been volatile in recent years, and many households are unsure whether to stay on a standard variable tariff, fix their rates, or move to a greener supplier. In 2025 the Ofgem price cap, ongoing wholesale cost changes and new environmental policies mean that the tariff you were on last year may no longer be the best choice for your home.

Comparing UK home energy suppliers in 2025 helps you understand:

  • Which suppliers are offering the cheapest unit rates and standing charges in your area
  • Whether a fixed-rate tariff could protect you from future price rises
  • How much extra — if anything — you would pay to switch to a 100% renewable or low-carbon tariff
  • What support is available if you're a low-income or vulnerable household

Our comparison makes it simple to see clear prices, contract terms and estimated annual costs side by side so you can pick a home energy deal that suits your budget and lifestyle in 2025.

How our UK home energy comparison works

Our service connects you with trusted UK home energy suppliers, from the biggest brands to innovative challenger providers. We focus solely on domestic households — not business energy — so the tariffs you see are tailored for home use.

When you complete the short form above, we'll:

  1. Use your postcode to identify which suppliers and tariffs are available at your address
  2. Estimate your annual usage based on your bills or typical consumption for a similar property
  3. Show you a comparison table with estimated annual cost and monthly direct debit amounts
  4. Highlight deals that may save money compared with your current or default tariff
  5. Allow you to select a tariff and complete your switch request online

Your supply will not be interrupted. Your new supplier agrees a switch date, handles meter readings and notifies your existing supplier on your behalf.

What you'll need to compare accurately

You can still compare without a bill, but for the most accurate quotes in 2025, it helps to have:

  • Your latest gas and electricity bill (or separate bills)
  • Details of your current tariff name and supplier
  • Your annual usage in kWh (kilowatt hours) or your monthly spend
  • Whether you're on a single-rate or Economy 7 meter

If you don't have this to hand, just give your best estimate of your monthly energy spend and we'll do the rest.

Types of UK home energy tariffs you can compare in 2025

Fixed-rate tariffs

Lock in unit rates for 12, 24 or even 36 months. Ideal if you want certainty over your monthly bills and protection from future price rises.

Variable tariffs

Prices can go up or down, usually in line with the Ofgem price cap. Often the default tariff you're moved to when your fix ends.

Dual fuel deals

Get gas and electricity from the same supplier. Dual fuel tariffs can be convenient and may offer discounts or simpler billing.

Green & EV tariffs

Tariffs backed by renewable electricity, carbon offset gas or off-peak rates for charging an electric vehicle at home.

Compare leading and challenger UK home energy suppliers

Our 2025 comparison includes a wide range of domestic energy suppliers so you can weigh up price, customer service and green credentials, not just brand recognition.

You'll see tariffs from well-known suppliers such as:

Alongside the biggest names, we highlight competitive offers from smaller, challenger brands that may provide cheaper rates or stronger environmental commitments.

Each tariff listing shows key details including payment method, contract length, exit fees, green credentials and any special features such as smart meter or EV charging support.

What to look for when choosing a supplier

  • Unit rates & standing charges — both affect your total annual cost.
  • Contract length — shorter fixes offer flexibility, longer fixes give price stability.
  • Exit fees — check whether there's a fee for leaving early.
  • Customer service ratings — reviews, response times and support options.
  • Green credentials — fuel mix disclosure and renewable sourcing.
  • Smart meter support — some tariffs require or reward smart meter usage.

How much could you save in 2025?

Your exact savings depend on your home's size, where you live, how you heat your property and how much energy you use. However, many households that haven't switched for a few years discover they're on an expensive default tariff and can cut costs by moving to a more suitable deal.

When you compare home energy suppliers with us, we estimate your:

  • Annual cost on each new tariff
  • Monthly direct debit or bill amount
  • Potential saving or extra cost vs your current deal

This makes it easy to see if a fixed tariff, green plan or dual fuel deal is worth switching to in 2025.

Understanding your home energy bill

To compare like-for-like tariffs, it helps to understand the main parts of your bill:

  • Unit rate — the price you pay for each kWh of electricity or gas you use.
  • Standing charge — a daily fee that covers the cost of supplying your home, regardless of usage.
  • Tariff type — fixed, variable, Economy 7 or specialist products like EV tariffs.
  • Payment method — many suppliers offer a discount for paying by monthly direct debit.
  • Contract end date — the date your fix ends or terms change.

Frequently asked questions about comparing home energy in 2025

Yes. Even with the Ofgem price cap in place, suppliers now offer a wider choice of fixed, variable and green tariffs. If you've been on a standard variable or default tariff for a while, you may be able to reduce your annual bill, lock in prices for peace of mind, or move to a greener supply that better matches your priorities.

No. Your energy supply is never interrupted when you switch home energy supplier. The gas and electricity come through the same pipes and wires — only the company that bills you changes. Your new supplier will arrange the switch date and manage the process behind the scenes.

Not always. Some 2025 tariffs do require a smart meter, especially time-of-use or EV-specific tariffs. However, there are still many competitive fixed and variable deals for homes with traditional meters. During your comparison you can see which tariffs require a smart meter and choose accordingly.

This page and form are specifically for home (domestic) energy only. Business energy tariffs are structured differently, and suppliers treat them separately. If you also need to compare business energy for a company or commercial property, please use our dedicated business energy comparison service.

Comparing and submitting your switch request typically takes less than 10 minutes online. The actual switch between suppliers usually completes within 5–15 working days, depending on the supplier and whether you need a new meter or any additional checks.

The best time is usually when your current fixed deal is ending or if you've been on a default tariff for some time. Many households also review their tariff before winter, when usage tends to rise. In 2025, suppliers may release new tariffs throughout the year, so it's worth checking your options regularly.
