E (Gas & Electricity) is a British-owned energy supplier based in Birmingham that specialises in Pay As You Go (PAYG) energy. It supplies more than 300,000 customers across the UK, and its focus is on keeping prepayment simple and good value.
E is currently a Which? Recommended Provider, it has no exit fees, and it takes part in the Warm Home Discount scheme. Smart meter customers also get friendly credit hours, so their supply won't be cut off during evenings, weekends or bank holidays.
E is a prepayment specialist. If you top up your meter rather than paying by Direct Debit, it is one of the better-rated suppliers, with strong Which? scores and no exit fees. If you want to pay by Direct Debit or want green or time-of-use tariffs, it isn't the right fit.

E, officially E (Gas and Electricity) Limited, is a British-owned, independent energy supplier with its head office at Trinity Park in Birmingham.
Unlike most suppliers, it has built its business almost entirely around prepayment customers. It now supplies more than 300,000 homes, and its strong customer service results have made it a Which? Recommended Provider.
E supplies gas and electricity on a prepayment standard variable tariff. That means you pay for your energy before you use it, by topping up your meter, and your unit rates and standing charges move in line with the Ofgem price cap for prepayment customers.
You can be with E on a traditional key or card meter, or on a smart prepayment meter. Smart meters are free to install, and they come with some useful extras.
| Smart meter feature | What it means for you |
|---|---|
| Friendly credit hours | Your supply won't be cut off during evenings, weekends or bank holidays, even if your credit runs out, when it would be hard to top up. |
| Emergency credit | Up to £15 of emergency credit to keep you going until you can top up. You pay this back from your next top-up. |
| No standing charge on unused days | On days when you don't use any energy, you won't be charged a standing charge. |
| Online and app top-ups | Top up from your phone and check your balance and usage in the MySmartE app. |
Prepayment isn't the expensive option it used to be. Since Ofgem levelled prepayment standing charges in 2024, the prepayment price cap now sits slightly below the Direct Debit cap. See our guide to prepayment meters for more.
There are several ways to top up, depending on which type of meter you have.
| Top-up method | How it works |
|---|---|
| PayPoint and Payzone | Top up with cash or card at local shops displaying the PayPoint or Payzone sign. |
| Post Office | Top up over the counter at your local Post Office. |
| Online or in the app | Smart meter customers can top up online or through the MySmartE app, without leaving home. |
E performs well in independent customer service surveys, although its results vary depending on who is asking.
E is a Which? Recommended Provider. In the most recent Which? energy survey, carried out between September and November 2025, it scored 79% overall and came 4th among the suppliers surveyed. Which? gave it full marks for smart meters and switching, and one of the highest scores for complaint handling.
| Which? category | Rating |
|---|---|
| Customer service overall | 4 out of 5 |
| Ease of contacting | 4 out of 5 |
| Clarity of statements | 4 out of 5 |
| Value for money | 3 out of 5 |
| Accuracy of payments | 3 out of 5 |
The main criticism from Which? was the limited range of contact options, as E doesn't offer live chat or social media support.
Citizens Advice gave E a customer service rating of 3.4 out of 5 for April to June 2026, placing it 9th among suppliers. It scored full marks for billing and metering, and its average call waiting time was just 45 seconds. Its weakest area was the number of complaints it received.
| Citizens Advice measure | Score |
|---|---|
| Billing and metering | 5 out of 5 |
| Contact waiting time | 4.4 out of 5 |
| Customer commitments | 3 out of 5 |
| Fewer complaints | 1.5 out of 5 |
The electricity supplied by E is generated from a variety of primary fuels, including natural gas, coal, nuclear and renewable sources. Like all energy suppliers, E buys electricity from generators who produce it using these fuels, and the proportion of each fuel used makes up E's fuel mix.
| Supplier | Coal | Gas | Nuclear | Renewable | Other | CO2 (g/kWh) | Nuclear Waste (g/kWh) |
|---|
E doesn't currently generate its own renewable electricity or offer green or time-of-use tariffs. If renewable energy is a priority for you, see our guide to green energy tariffs.
There are three ways to contact E.
| Contact method | Details |
|---|---|
| Phone | 0333 103 9575 8am to 7pm, Monday to Friday 9am to 5pm, Saturday |

E is a strong choice if you are on a prepayment meter, or you prefer to pay as you go. Its Which? Recommended Provider status, fast call answering and friendly credit hours make it one of the better-rated suppliers for prepayment customers, and there are no exit fees if you change your mind.
It is less suited to you if you want to pay by Direct Debit, want a fixed price deal, or want a green or time-of-use tariff, as E doesn't offer any of these.
As always, compare prices using your own postcode and usage before switching, as rates vary by region.
