About

Who is Utilita?

Registered as Utilita Energy Limited, Utilita 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 Chandler's Ford, Hampshire, where it runs its senior management, customer operations and regulatory liaison with Ofgem.

Utilita was established in 2003. A longer track record means more years operating under Ofgem rules and a wider history of customer feedback, billing systems and regulatory interactions.

Utilita operates independently — it is not part of a larger corporate group. This typically means faster decision-making but less wholesale-market scale.

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

Fuel mix

Utilita electricity fuel mix (April 2023 to March 2024)

Utilita declares <strong>100% renewable electricity</strong> on its domestic supply, backed by Renewable Energy Guarantees of Origin (REGOs) under Ofgem Fuel Mix Disclosure rules. The certificates match annual customer consumption; the electrons physically delivered to each home come from the wider GB grid.

Current tariffs

Utilita tariffs: as of 14 May 2026

Utilita is a domestic prepayment specialist, so its tariffs sit under the Ofgem prepayment price cap, which Ofgem reviews on 1 January, 1 April, 1 July and 1 October. Smart Energy uses a distinctive two-tier unit rate: a higher "Anytime" rate applies to the first slice of daily usage, then a lower "Saver" rate kicks in once you cross the daily threshold, replacing the conventional daily standing charge. The traditional (key / token) tariff keeps the conventional standing-charge structure. Rates below are the Q2 2026 Ofgem prepayment cap averages across England, Scotland and Wales (incl. VAT).

Timeline

Utilita — key dates

A short timeline of the Utilita brand — founding, milestones, regulatory events.

  1. 2003

    Utilita Energy Limited is founded in Chandler's Ford, Hampshire by Bill Bullen, with a deliberate focus on the prepayment segment that the Big Six largely neglected at the time.

  2. 2008

    Utilita becomes the first UK supplier to install a smart meter at a domestic property, in Darlington, five years before Ofgem's national SMETS rollout begins in earnest.

  3. 2019

    Utilita takes on the customer base of Our Power, a Scottish supplier that ceased trading, under Ofgem's Supplier of Last Resort scheme.

  4. 2021

    Customer base passes 800,000 households, making Utilita the largest dedicated smart-prepayment supplier in the UK (≈2.7% market share). Utilita Arena Sheffield naming partnership is announced.

  5. 2023

    Ofgem closes most of the prepayment-versus-direct-debit cost gap with a re-baselined prepayment price cap, reducing the structural premium that prepay customers had historically paid.

  6. 2026

    Utilita continues as a prepay-only specialist, with the two-tier Smart Energy Anytime + Saver tariff as the default for new and migrated SMETS2 customers and a smaller pool of legacy traditional-meter customers still on flat unit rates.

Common questions

Utilita — frequently asked questions

Utilita 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 Utilita 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. Utilita 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. Utilita 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.

You can reach Utilita on 0330 3337 442, Mon-Fri 8 a.m. to 8 p.m.; Sat 8 a.m. to 5 p.m. (blue top-up card). For a full breakdown of phone lines (emergency, prepayment, HomeCare, bereavement, Welsh, Relay UK), see the Utilita contact page.
