Q: How do I switch to Boost?

Boost will arrange the transfer with your current supplier, including the final meter reading and the closing bill.

Q: Are there exit fees on Boost tariffs?

About

Who is Boost?

Registered as Boost Power Ltd, Boost uses this legal name for Ofgem licence filings, contracts and any formal communications. The trading name customers see on bills is the shorter, more recognisable form.

The company is headquartered in Bristol, where it runs its senior management, customer operations and regulatory liaison with Ofgem.

Boost was established in 2017. A longer track record means more years operating under Ofgem rules and a wider history of customer feedback, billing systems and regulatory interactions.

Boost is part of the OVO Energy group, which provides shared governance, financial backing and a broader pool of expertise in trading, hedging and regulatory work.

The company is regulated by Ofgem, the UK's energy regulator, and its complaint handling falls under the Energy Ombudsman alternative dispute resolution scheme.

Common questions

Boost — frequently asked questions

Boost is regulated by Ofgem and operates under a standard domestic-supply licence. Whether it is the right supplier for your household depends on your unit rate, standing charge, customer-service rating and any add-on services (HomeCare, Warm Home Discount eligibility). Always quote your annual kWh consumption when comparing prices — the headline rate alone does not predict your bill.

Switching to Boost takes about five working days under the new Faster Switching service, and your supply is never interrupted. Sign up online with your address, postcode and a recent meter reading. Boost will arrange the transfer with your current supplier, including the final meter reading and the closing bill.

The UK grid is supplied by a mix of gas, nuclear, wind, solar, biomass and imports. Boost declares its fuel mix annually under Ofgem rules — see the fuel-mix section above for the current figures. Some tariffs are sold as 'green' or '100% renewable', which means the supplier matches your annual consumption with renewable electricity certificates (REGOs) rather than physically delivering renewable electrons to your home.

Most UK fixed-term tariffs include an exit fee (typically £25-£75 per fuel) if you switch before the contract ends. You can switch without an exit fee in the last 49 days of your contract. Variable tariffs (including the default tariff capped by the Energy Price Cap) have no exit fees.
