With gas and electricity comparison sites currently not fully active (they are showing some tariffs, but not all suppliers), it is difficult to quickly compare energy suppliers and find the cheapest gas and electricity prices.
To help find the cheapest energy supplier, we have manually gone to every provider’s website to get a quote and compare gas and electricity using the same criteria* for each.
This means we can give you a quick overview of the cheapest gas and electricity prices across all energy suppliers in the UK right now for April 2024.
We’ve broken the tariffs down into two tables, one showing the cheapest fixed tariffs available and the other the cheapest variable tariffs.
Our top rated supplier Octopus Energy is currently offering £50 credit to any new customer that uses our referral link. Click below to see why we rate them so highly and get your £50.
We have also split each tariff out by gas and electricity, so if you are only looking for a single fuel, then you can still use our research to help you find the cheapest tariff.
It is important to not just look at price when considering switching energy suppliers, so we have linked to our reviews of each supplier in each table.
For those wanting a quick answer, we have summarised the cheapest suppliers for gas and electricity based on current prices below:
- Cheapest electricity only: Fuse Energy at £70.53 per month
- Cheapest variable gas and electricity: Octopus Energy at £141.66 per month (plus get £50 when signing up!)
- Cheapest fixed gas and electricity (with credit included): Octopus Energy at £134.44 per month
- Cheapest fixed gas and electricity (without credit included): Outfox The Market at £134.58 per month
*These prices are based on the average energy usage of a 3-bedroom house in the East Midlands for dual fuel, paying by direct debit. You will likely get a different estimate with your own details.
Cheapest variable tariff prices – best deals (April 2024)
We have compared all the variable tariffs we could find that are currently available to new customers. A few things to note with this:
- Some of these suppliers may offer other incentives, e.g. Sainsbury’s offer Nectar points.
- The cheapest supplier is not necessarily the best, so please check reviews before switching.
- All of the variable tariffs have no exit fees
You can see the full list of variable, dual fuel tariffs below:

| 100Green | Sparkling | £78.55 | £87.06 | £165.61 | £1,987.32 |
As you can see from the table, for dual fuel, Octopus Energy are the cheapest right now.
All the energy suppliers offer similar rates on their variable tariff due to the price cap.
Two that stand out at the higher end, however, are Ecotricity and 100Green. This is because they offer green gas, which makes them more expensive. If you are looking for the greenest suppliers, they are worth considering. We also have a guide on the best green energy suppliers in the UK.
Cheapest fixed tariff prices – best deals (April 2024)
In this table, we have compared all fixed tariffs we could find that are currently available to new customers. A few things to note with this:
- Some of these suppliers may offer other incentives, e.g. Sainsbury’s offer Nectar points.
- There are different exit fees between different suppliers
- If a supplier had more than one fixed tariff available, we chose the cheapest one.
- The cheapest supplier is not necessarily the best, so please check reviews before switching.
If you exclude the £50 credit, Outfox the Market has the cheapest overall fixed tariff.
Both of these tariffs also have no exit fees.
The full list of fixed, dual fuel tariffs is below:
| Supplier Name | Tariff Name | Monthly Electric Cost | Monthly Gas Cost | Total monthly cost | Total yearly cost | Exit fee (per fuel) |
|---|---|---|---|---|---|---|
| Outfox The Market | Fix’d Dual Mar24 v1.0 | £71.92 | £62.67 | £134.58 | £1,615.00 | £0 |

| 100Green | Sparkling | £81.09 | £87.34 | £168.43 | £2,021.13 | £0 |
This table follows a similar pattern to the variable tariffs, although there is more variation in the rates offered.
In this case, the cheapest fix actually has no exit fees, but if you are looking at other tariffs, it is worth considering these fees as they could make your costs much more expensive if you choose to switch suppliers before your contract ends.
