What HAVENWISE LIMITED does

Havenwise Limited is a UK-based software company that operates a cloud-connected heat pump optimization platform. Its core product, the Havenwise App, links to internet-connected heat pumps from Mitsubishi, Vaillant, Samsung, and Daikin via manufacturer APIs (MELCloud, myVaillant, SmartThings, Onecta) and uses an ML-driven digital twin of the home's thermal behavior, weather forecasts, and time-of-use energy tariffs to automatically tune flow temperatures, schedule pre-heating, and shift heating and hot water production into cheaper tariff windows. A complementary Havenwise Installer Portal (marketed as Havenwise Pro) enables professional installers to onboard customers, monitor installed systems remotely, view fault logs, and reduce callback visits. The company also supports optional Shelly room temperature sensors and integrates with UK smart tariffs including Octopus Agile, Octopus Cosy, and E.ON Next Pumped.

The business runs on a self-serve consumer subscription priced at £7/month with a one-month free trial, processed via Stripe. Distribution is dual-channel: direct-to-consumer through the iOS and Android app stores and via partnerships with heat pump installers (notably IMS Heat Pumps Limited and AAC), who bundle Havenwise with new installations. Marketing is supported by earned media (Financial Times, The Telegraph, Beta Talk podcast, Renewable Heating Hub, Energy Stats UK), a Facebook user community, referral credits (£10–£20), and an installer-focused landing page. Backed infrastructure runs on Google Cloud Platform, Supabase, Vercel, Stripe, Intercom, and PostHog, with data hosted in UK/EU regions. Headcount is reported at 1–10, the firm is privately held and founder-led with no disclosed funding rounds, and the entire operation is concentrated in the United Kingdom.

Revenue is generated through monthly subscription fees; per-customer ARPU implies a small but growing subscriber base. Customer evidence is limited to named residential testimonials reporting annual savings of £276–£861 (and COP measurements of 4.6–4.9), and the company offers a £10–£20 referral incentive that has been temporarily increased to £20 through March 2026. No enterprise contracts, OEM licensing, or adjacent revenue lines (e.g., data licensing to utilities) are disclosed.

Core offering

Havenwise provides a cloud-based heat pump monitoring, optimization, and control service via a consumer mobile app and a separate installer portal. The service connects to internet-connected heat pumps from supported manufacturers (Samsung, Vaillant, Mitsubishi, and Daikin) through their cloud APIs and uses machine learning, predictive analytics, and a digital twin model of the property to automatically tune flow temperatures, pre-heating schedules, and hot water cycles based on weather forecasts, energy tariffs, and how the home heats up. Revenue is generated through a £7/month subscription with a 1-month free trial for homeowners.

Product overview

Havenwise Limited is a UK-based heat pump optimisation company offering a cloud-connected smart control platform. The primary product is the Havenwise App — a mobile application for homeowners that replaces traditional weather compensation with machine learning-driven algorithmic control, using real-time heat pump data, weather forecasts, and energy tariff information to automatically schedule and optimise heat pump operation for comfort and cost savings. A complementary Havenwise Installer Portal enables professional heat pump installers to onboard customers, monitor system performance remotely, and access diagnostic data. Havenwise connects natively to Mitsubishi (MELCloud), Samsung (SmartThings), Vaillant (myVaillant), and Daikin (Onecta) heat pump platforms, and integrates with time-of-use energy tariffs and optional Shelly temperature sensors.
