What Heatmiser does
Heatmiser, operating as IMI Heatmiser since June 2025, is a UK-based designer and manufacturer of smart heating and cooling control systems founded in 1968 by Gordon Kay and headquartered in Blackburn, Lancashire. The company was acquired by IMI plc in 2022 for £110m and now sits within IMI's Climate Control division alongside IMI Heimeier, IMI Pneumatex, IMI TA, and IMI Flow Design. Its core product is the neo smart control system — a multi-zone platform using RF 868 MHz mesh networking (where mains-powered neoStat devices act as repeaters), WiFi 802.11b/g/n, and a cloud-connected neoHub (Gen 2, Gen 3, or Mini) that supports up to 32 paired devices per hub. The portfolio spans wired, wireless, and RF thermostats (neoStat v3, neoStat-e, neoStat-hw, neoStat-HC, neoStat-12v, neoAir v3/v4, Slimline-RF), touchscreen models (Touch v2, Touch Carbon, Touch-E), the neoFlo smart thermostatic radiator head, and supporting accessories including neoPlug, RF Switch v2, UH8-RF v2 wiring centres, thermal actuators, and remote sensors.
The neo system integrates natively with Amazon Alexa, Google Home, Apple HomeKit, IFTTT, Samsung SmartThings (added May 2026), and Control4, and is controlled via the neoApp on iOS and Android (650,000+ registered users). Heatmiser monetises through one-time hardware sales with no subscription fees, distributing via direct e-commerce (heatmisershop.co.uk), a UK installer network supported by the Heatmiser Installer App and Pro-Training Days, plumbing/heating wholesalers, OEM/private-label partnerships with system design houses, and direct sales to housing developers and build-to-rent operators. Customer segments include homeowners (residential consumers seeking energy efficiency and multi-zone control), heating installers, wholesalers and distributors, housing developers, UK landlords navigating Renters' Rights Act compliance, and system design houses requiring custom controls. Certifications include ISO 9001 and UKAS accreditation.

Heatmiser competitors and assessment
Company assessmentDirect peers
- tado°: German smart thermostat company with strong UK and European presence, offering multi-zone heating control and smart home integrations. Directly competes with Heatmiser in the same product category and customer base (homeowners + installers), differentiated by its subscription-based revenue model.
- Hive (British Gas / Centrica): UK smart home brand owned by Centrica / British Gas, with smart thermostat as its flagship product. Direct competitor in the UK market leveraging the British Gas installer network and energy supplier customer base — overlapping heavily with Heatmiser's installer channel and homeowner segments.
- ecobee: Canadian smart thermostat specialist (now partly owned by Generac) focused on multi-zone residential climate control with broad smart home integration. Directly comparable on product category, multi-zone architecture and smart home integrations, though primarily North American rather than UK-centric.
- Salus Controls: UK-based smart heating controls manufacturer offering wireless thermostats, wiring centres, and smart home integration. Closest comparable peer by geography, product line (thermostats, UFH controls, multi-zone hubs) and reliance on the installer/wholesaler channel.
- Netatmo (Legrand): French smart home brand (now Legrand-owned) producing smart thermostats and heating controls with HomeKit, Google Home and Alexa integration. Direct competitor in smart thermostat hardware with overlapping partner ecosystem, albeit with a more consumer-DTC orientation than Heatmiser.
Broad incumbents
- Google Nest: Alphabet-owned smart thermostat brand that defined the category and benefits from deep Google Home integration, brand spend and consumer mindshare. Operates in the same residential smart thermostat category as Heatmiser but with vastly broader resources and ecosystem reach.
- Honeywell Home: Honeywell's residential heating controls and smart thermostat division, covering programmable, WiFi and connected thermostats for residential and light commercial use. Comparable on product category and HVAC control functionality, but operates as part of a much wider building technologies portfolio rather than focusing on UK installers.
- Wiser (Schneider Electric): Schneider Electric's smart heating control product line (formerly Drayton Wiser) offering multi-zone smart thermostats with app control and voice integration. Competes head-on with Heatmiser in UK installer channels and housing developer specifications, backed by Schneider's global scale.
- Danfoss Heating: Danfoss's heating controls and hydronic division producing smart thermostats, wiring centres and UFH actuators. Compares to Heatmiser on product categories and OEM/private-label capabilities, but at significantly larger scale and within Danfoss's broader climate solutions portfolio.
- Worcester Bosch: Leading UK boiler and heating systems manufacturer (Bosch Thermotechnology subsidiary) that supplies compatible smart controls and integrated heating solutions to UK installers. Adjacent competitor for installer mindshare and housing developer specifications on complete heating system packages.
