Compare home energy prices and start saving today

Why compare gas and electricity prices in the UK?

Energy is one of the largest regular costs for most UK households. If you have not switched energy supplier or tariff in the last 12–18 months, there is a strong chance you could be paying more than necessary for your gas and electricity.

When you compare energy prices, you can:

• Identify cheaper tariffs that better match your home’s energy usage.
• Choose between fixed and variable rates depending on how much certainty you want over future prices.
• Review the latest offers from established suppliers and newer challenger brands.
• Switch online without paperwork, phone queues or engineer visits.

Regular comparison ensures you remain on a competitive home energy deal, instead of reverting to more expensive standard tariffs when fixed deals end.

How does comparing home energy prices work?

Our comparison process is designed to be quick and straightforward. You do not need to be an expert in unit rates and standing charges — we do the hard work for you.

1. Tell us about your home.
   Enter your postcode, property type and whether you are looking for gas, electricity or dual fuel.
2. Share details of your current tariff (if you know them).
   Providing your current supplier, tariff name and usage in kWh or spend amount helps us calculate potential savings more accurately.
3. Compare available tariffs.
   We show you a range of offers from participating UK suppliers in your area, including estimated annual costs.
4. Choose and switch online.
   Once you have picked a tariff that suits you, complete your switch online. Your new supplier will contact you to confirm the changeover date.

Your gas and electricity are delivered through the same pipes and wires, and there is no break in supply at any stage. Meter readings are shared between suppliers to ensure a smooth handover.

Types of home energy tariffs you can compare

The best energy deal for your household depends on how you use energy and how much certainty you want over what you pay. When you compare energy prices, you will typically see:

Fixed rate tariffs

A fixed tariff keeps your unit rates and standing charge at an agreed level for the length of the contract (for example 12 or 24 months). Your monthly payments can still change if your usage changes, but the price you pay per unit of energy does not. Fixed tariffs can be useful if you want protection from potential price rises.

Standard variable tariffs

On a standard variable tariff, your prices can go up or down when your supplier changes its rates. These tariffs usually have no exit fees, and you may move to them automatically when your fixed deal ends. Variable tariffs can offer more flexibility, but you could pay more if prices rise.

Time-of-use tariffs (including Economy 7)

Some electricity tariffs offer cheaper rates at off-peak times and higher rates during peak hours. Economy 7 and similar tariffs may suit homes with storage heaters or electric vehicles that can be charged overnight, but they are not right for everyone. Comparing these tariffs helps you see whether you would benefit.

Green and renewable tariffs

Many suppliers offer tariffs that support renewable electricity generation or carbon offsetting for gas. These may use 100% renewable electricity or invest in climate projects. Green tariffs can be competitive on price, so it is worth including them in your comparison if lowering your carbon footprint is important to you.

What information do I need to compare UK energy prices?

You can start comparing with just your postcode and a rough idea of your energy use. However, having a recent bill to hand will give the most accurate results. Useful details include:

• Your current supplier and tariff name.
• Whether you pay by direct debit, on receipt of bill or prepayment meter.
• Your annual usage in kWh for gas and electricity (or monthly/annual spend).
• Whether you have a smart meter and if you prefer paperless billing.

If you do not know all of these details, we can estimate your usage based on your property type and number of occupants. You can still compare tariffs and get an indication of potential savings.

Is it a good time to switch energy supplier?

Wholesale energy markets can be volatile, but that does not mean you should stay on an expensive tariff indefinitely. Some key points to consider:

• If you are on a standard variable tariff and have not switched in a while, comparing prices can reveal cheaper alternatives.
• If your fixed deal is ending soon, it is usually worth checking your options before you roll onto a default tariff.
• If you are worried about further price rises, a fixed tariff may offer more certainty over your monthly budget.
• Some tariffs come with exit fees, so check your current terms before committing to a switch.

Our comparison makes it easy to see estimated annual costs side by side, helping you decide whether switching now makes financial sense for your household.

How to reduce your home energy bills beyond switching

Comparing and switching to a cheaper tariff is one of the fastest ways to save, but combining it with sensible energy-saving habits can lower your bills even further. Simple steps include:

• Turning your thermostat down by 1°C, which can reduce heating costs over the year.
• Using smart heating controls or TRVs to heat only the rooms you use most.
• Replacing older bulbs with LED lighting throughout your home.
• Switching off appliances at the plug instead of leaving them on standby.
• Running washing machines and dishwashers with full loads and at lower temperatures where possible.
• Improving insulation and draught-proofing to keep heat in for longer.

These measures, combined with a competitive tariff from your chosen supplier, can help you get your household energy costs under control.

Frequently asked questions about comparing home energy prices

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

No. Your energy supply is continuous. The switch only affects who bills you and the tariff you are on. The physical supply through pipes and cables remains the same.

How long does it take to switch supplier?

In most cases, switching takes around 5–15 working days from the date you agree your new tariff, although it can vary by supplier. You will receive confirmation of your go-live date and may be asked to provide a meter reading.

Do I have to pay to compare or switch?

No. Comparing energy prices and switching through our service is free to use for households. You are under no obligation to switch after seeing your results.

What if I am in debt with my current supplier?

If you owe money on your current account, you may still be able to switch, but your options could be limited, particularly if you use a prepayment meter. Always speak to your current supplier to discuss your situation.

Can I switch if I rent my home?

Tenants can usually choose their own energy supplier if they are responsible for paying the bills directly. Check your tenancy agreement for any restrictions and speak to your landlord if you are unsure.

Do I need a smart meter to get the best deals?

No, but some tariffs are designed specifically for homes with smart meters. When you compare tariffs, you can filter or review options based on whether you already have a smart meter installed.
