Last updated: March 2021

When choosing the best energy rates for your home, it’s important to keep changing suppliers. Indeed, Ofgem actively encourages energy consumers to switch suppliers regularly. It keeps the market competitive and keeps market prices consistently low. However, it’s also important to keep changing tariffs. Letting your tariff roll over after it expires can put you on a needlessly expensive standard tariff with a less than favourable rate. Bulb is one of the most popular and trusted green energy suppliers in the country, bringing 100% renewable energy and carbon-neutral gas to 1.6 million customers across the UK. But do Bulb tariffs in 2020 give you the value for money that you expect?

Bulb Tariffs and Prices

Bulb prides itself on offering energy consumers “fair prices that stay fair”. Indeed, a look at their tariffs page reveals that they are consistently cheaper than any of the “Big 6” suppliers, and even compares favourably to other green tariffs offered by suppliers like Outfox The Market and Octopus Energy.

Unlike most suppliers, Bulb do not offer a fixed rate tariff. Instead, it offers different versions of its variable “Vari-Fair” tariff for customers with standard credit meters, economy 7 credit meters, and prepayment meters to domestic customers. It also offers business tariffs for SMEs.

Please be aware that rates described are averaged out across the country. As such, your rates may vary slightly, depending on where in the UK you live.

Let’s take a closer look…

Bulb standard tariff

Bulb’s standard tariff bucks a few common energy industry trends. There are no fixed rates, and they are committed to ensuring that prices remain both variable and fair (hence “Vari-Fair”) to ensure that the rates accurately reflect the cost of energy. As their website states:

“Our variable plans reflect the true cost of energy. And we don’t do fixed contracts or exit fees, so you’ll never pay more just for sticking around”. This means that you can come and go as you please without having to worry about exit fees.

Their standard Vari-Fair tariff rates are as follows:

Energy Cost Price
Electricity unit rate 14.107p per kWh
Gas unit rate 3.061p per kWh
Electricity standing charge 19.79p per day
Gas standing charge 20.44p per day
Total estimated cost per month £76.94
Total estimated cost per year £923.26

Rates are inclusive of VAT at 5%.

As we can see, this is significantly below Ofgem’s Energy Price Cap, which as of October 2020 is £1,042 per year for both fuels.

Bulb prepayment tariffs

Bulb also offers tariffs for customers with prepayment meters. While these unit rates are cheaper than those paid by customers with credit meters, this saving is offset by a higher standing charge.

Below we’ll look at rates for standard prepay meters and economy 7 prepay meters.

Bulb standard prepayment tariff

Those with a standard prepayment tariff that does not have dual rates will pay:

Energy Cost Price
Electricity unit rate 13.661p per kWh
Gas unit rate 3.208p per kWh
Electricity standing charge 25.91p per day
Gas standing charge 28.31p per day
Total estimated monthly cost £81.59
Total estimated annual cost £979.03

Rates are inclusive of VAT at 5%.

Bulb Economy 7 tariff

For customers with Economy 7 meters, the Vari-fair tariff has two different rates for day and night. While some tariffs have very little difference between night and day rates, Bulb’s is fairly pronounced. Economy 7 hours usually fall between 10pm and 8am, depending on where in the country you are.

Economy 7 electricity rates for credit and prepayment meters are as follows:

Meter Type Day unit rate (per kWh) Night unit rate (per kWh) Standing charge (per day) Estimated annual electricity price
Credit meter 16.447p per kWh 7.455p per kWh 19.79p £604.44
Prepayment meter 16.086p per kWh 7.109p per kWh 25.91p £611.81

Annual estimates assume 58% usage during daytime hours and 42% usage during night hours.

Rates are inclusive of VAT at 5%.

Bulb business tariffs

If you run a business, it’s likely that your customers (and your staff) expect you to take active steps to make your business as environmentally friendly and carbon-neutral as possible. Switching to a renewable supplier is a good place to start. Bulb offers business tariffs for SMEs that, while not necessarily the cheapest on the market, are nonetheless competitively priced. What’s more, Bulb’s business energy tariffs do not have the lengthy tariffs and hefty exit fees that are usually associated with business energy.

Bulb’s business standing charges are 27.40 pence per day for both electricity and gas. Unit rates will depend on the size of your business and peak load times. Their business energy page places their average annual bill at £2,161.

Bulb tariffs compared: Which is the cheapest tariff?

Tariff Name Estimated Monthly Cost Estimated Annual Cost
Vari-Fair Standard Tariff £76.94 £923.26
Vari-Fair Prepay £81 £979.03
Vari-Fair Economy 7 (Electricity Only) £50.98 £611.81

When comparing Bulb’s domestic energy tariffs, its standard economy 7 Vari-Fair rate works out the cheapest for customers with electricity-only. While day rates are slightly higher than standard credit meter rates, the lower standing charges help to make this the most economical tariff.

However, all of Bulb’s tariffs (including prepay tariffs) are significantly below the Energy Price Cap.

Bulb price changes in 2020

In September 2020, Bulb went against the grain, increasing the price of its Vari-Fair tariff by an average of £51 for dual fuel customers, at a time when most were reducing their prices in line with the new price cap. While this may be considered a red flag, it really speaks more to the excessive pricing of other suppliers than it does to Bulb. Even with this price rise considered, Bulb’s energy prices are still significantly below Ofgem’s cap.
