About

Who is Utility Warehouse?

Registered as Utility Warehouse Limited, Utility Warehouse 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 London, where it runs its senior management, customer operations and regulatory liaison with Ofgem.

Utility Warehouse was established in 2002. A longer track record means more years operating under Ofgem rules and a wider history of customer feedback, billing systems and regulatory interactions.

Utility Warehouse is part of the Telecom Plus plc 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.

Fuel mix

Utility Warehouse electricity fuel mix (2024-25 reporting period)

Utility Warehouse declares a 100% renewable electricity fuel mix under Ofgem Fuel Mix Disclosure rules. The match is achieved through Renewable Energy Guarantees of Origin (REGO) certificates purchased to cover annual customer consumption, rather than a directly contracted physical generation portfolio. Gas supply is not green-matched by default.

Current tariffs

Utility Warehouse tariffs: as of 14 May 2026

Utility Warehouse sells two domestic energy plans: UW Value (the unbundled energy tariff) and UW Bundle (the same variable tariff with a loyalty discount applied for customers who also take broadband, mobile or home insurance). Both are variable, capped quarterly by the Ofgem Energy Price Cap, and have no exit fee. UW does not currently sell a fixed-price tariff, so there is no "fix vs. cap" decision to make — the choice is whether the bundle discount is worth taking the other services. Rates below are typical single-rate London / South East (Region 12) Direct Debit values, inclusive of VAT.

Common questions

Utility Warehouse — frequently asked questions

Utility Warehouse 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 Utility Warehouse 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. Utility Warehouse 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. Utility Warehouse 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 Utility Warehouse on 0333 777 0777, Mon-Fri 9 a.m. to 5:30 p.m.; Sat 9 a.m. to 4:30 p.m.. For a full breakdown of phone lines (emergency, prepayment, HomeCare, bereavement, Welsh, Relay UK), see the Utility Warehouse contact page.
