What does it mean that Bulb is in special administration?

As of November 2021, Bulb Energy is in special administration following its insolvency.

This process, known as a Special Administration Regime (SAR), is enforced by the energy regulator Ofgem. It protects customers by ensuring a continued energy supply when a large provider fails and becomes insolvent. The SAR’s long-term aim is to stop financial failure across the energy industry.

Bulb will operate as usual during the SAR, supplying energy to its customers and ensuring no changes to credit balances. If you’re already a Bulb customer, you don’t need to do anything.

If circumstances permit, Bulb can be sold at an appropriate time – either in full or in part. The government can recoup its funds once Bulb is sold.

What tariffs are available with Bulb business energy?

Bulb energy only offers one business plan. It’s a variable tariff that reflects the cost of wholesale energy, which means the cost of your tariff may fluctuate. If wholesale energy costs rise, Bulb will give you 30 days’ notice.

Unlike a fixed contract, your Bulb business energy tariff lasts as long as you want – there aren’t any end dates, renewals, or notice periods to think about. You can also leave whenever you want, without exit fees.

If you’d rather a fixed-term tariff with set prices for your business, you might want to look elsewhere.

You can also use the Bulb app, available on iOS and Android, to track your energy usage, submit readings, and manage multiple properties.
