What Acclimatise does

Acclimatise is a UK-based private company that rents temporary temperature control and air handling equipment, operating from its headquarters in Stoke-on-Trent, Staffordshire. Its product portfolio spans boilers (50 kW–1000 kW), chillers (20 kW–1000 kW, with capability down to -45°C for pharmaceutical use), air handling units, indirect fired heaters, air-to-air heat pumps, air purifiers/cleaners (including the TES 200 thermal disinfector), and power generators. Equipment is offered on short- and long-term hire with full installation, commissioning, and maintenance services, supported by a 24/7 emergency response capability and a remote system monitoring service that detects and resolves unit faults. Differentiated technical features include a heat pump chiller designed for temporary ice rinks that produces both hot and cold water, and a fleet that operates on diesel, gas, or bio-fuel.

The company sells primarily through an enterprise field-sales motion using specialist sales and installation engineers who conduct site surveys and design bespoke solutions. Customers are diversified across events, industrial/manufacturing, healthcare, food & beverage, education, government, military, and facilities management sectors, with named engagements including North West London Hospital, University of Bristol, fish farms in Scotland, and a major UK supermarket chain. Pricing is quote-based and project-specific, with no publicly disclosed tiers; multi-year contracts are offered alongside short-term emergency hire. Acclimatise holds multiple industry accreditations (ISO, CHAS, Safecontractor, Safehire, Refcom) supporting eligibility for public sector and regulated-industry work.

The company is a subsidiary of Cross Rental Services Group following a completed acquisition, and operates the "Acclimatise Events" sub-brand focused on the events industry. Geographic coverage is anchored in the West Midlands, Cheshire, Derbyshire, and Leicestershire, with claimed reach across the UK and Europe. Revenue model is essentially recurring equipment rental (subscription-style hire contracts) with a single dominant revenue stream and a content-marketing and referral-driven demand generation approach.
