What BoilerJuice does

BoilerJuice Ltd., founded in 2004 and headquartered in St. Ives (registered office) / Cambridge, UK, operates the country's largest independent online marketplace for domestic and commercial heating oil. The platform aggregates real-time quotes from a network of over 200 competing heating oil suppliers across England, Scotland, Wales, and Northern Ireland, allowing customers to obtain instant online quotes by entering their postcode, volume, oil type (Kerosene28, Premium Kerosene for boilers/AGAs, or Red Diesel/Gas Oil Class A2), and tanker type. The core product line has expanded beyond marketplace transactions to include the SG8 Smart Oil Tank Monitor (a CAT-M/NB-IoT pressure-sensor device with up to five-year battery life and 0.5% FSD accuracy), the Connected automated reordering subscription, a Payment Plan (monthly contributions from £10 building order credit), boiler servicing coordination with OFTEC and Gas Safe engineers, and direct sales of HVO-ready Sapphire liquid fuel boilers.

The company monetizes through a transaction fee on marketplace orders, hardware sales (£150 Smart Monitor plus £4.99/month data subscription after year one), subscription fees for Connected service, affiliate commissions from the Utility Warehouse utility-bundling partnership (up to 3p per litre discount), and embedded finance via iwocaPay for commercial customers (orders £150–£30,000). BoilerJuice employs 51-100 people, serves both domestic off-grid households (5% reduced-rate VAT) and commercial customers (5% VAT on orders ≤2,300L, 20% above), and is a wholly owned subsidiary of the independently-held holding company Welsummer Limited. A 2016 funding round was led by Livingbridge; no subsequent rounds are disclosed. CEO is Tim Buckman per the most recent primary source (Utility Warehouse partnership announcement, 2025-11-28), though a separate leadership dataset lists Lee Cowles as CEO, indicating a possible leadership change without a clear timestamp.

Cumulatively the platform has facilitated over 3 billion litres of heating oil to more than 500,000 customers since 2004 and reports 100,000+ four- and five-star Trustpilot reviews. The company is positioned at the intersection of a commoditized physical good and digital intermediation, with growth optionality from IoT-enabled reordering, multi-utility bundling, and commercial segment expansion, against a structural backdrop of declining UK off-grid oil-heating penetration.
