What iHeat does

iHeat, trading under the legal entity LeadsUK Ltd (Company No. 10884911), is a UK-based direct-to-consumer digital platform that sells and arranges installation of residential boilers and adjacent home energy products. The company is headquartered in Westhoughton, United Kingdom, with a core staff of 11–50 supported by a contracted network of 600+ Gas Safe registered engineers across the UK. Its core technology is an online quotation algorithm that converts property and heating-system inputs into instant fixed-price boiler recommendations, eliminating the need for on-site surveys and supporting a next-day installation promise.

The business model combines hardware sales (boilers, heat pumps, solar, battery storage, air conditioning, EV chargers) at fixed prices ranging from £1,899 to over £2,650 for boilers and £1,495+ for heat pumps and AC, with bundled installation delivered by the sister company iHeating Solutions Ltd (Company No. 12046243). Revenue is diversified across product sales, installation services, FCA-regulated credit broking commissions (FRN 843673) on 0% APR and long-term finance plans, and recurring aftercare such as annual servicing and power flushing (£300–£700). The go-to-market is exclusively self-serve online: customers complete a multi-choice survey, receive a fixed price quote, optionally apply for integrated finance, and book installation, all without sales-representative interaction.

iHeat's primary customer segment is UK residential homeowners, and the company markets on the basis of price transparency, speed (next-day installation for orders before 3pm), trust (Which? Trusted Trader accreditation and 10,000+ 5-star Trustpilot reviews), and convenience. Brand partnerships with Worcester Bosch, Vaillant, Viessmann, Ideal, Alpha, Glow-worm, and Baxi provide product breadth across budget to premium tiers, and the company is expanding into the renewable heat and EV charging segments to capture UK decarbonisation policy tailwinds.
