About

Q-Bot develops robotic systems that install underfloor insulation for suspended timber and concrete floors, providing an innovative solution for the over 8 million UK homes with suspended floors that suffer from cold draughts, higher heating bills, and reduced energy efficiency. The company's robotic technology crawls under houses through air holes, performing scanning to identify the optimal insulation approach before spraying accredited closed-cell foam under floorboards through small, discreet openings. Most installations are completed in one to two days with minimal disruption, allowing residents to remain in their homes during the process. Q-Bot's installations are independently tested to improve thermal performance by up to 79%, eliminate cold spots, save up to £560 annually on energy costs, and reduce moisture and pollutants while lowering risks of mould, rot, and radon. The company offers a 25-year insurance-backed guarantee and has served over 5,500 homes with a 93.8 Net Promoter Score. Q-Bot's SWARM Platform enables scalable deployment of its robotic insulation technology. Founded in 2012 and headquartered in London, United Kingdom, Q-Bot has raised $14.5M in Series A funding from investors including EMV Capital, WealthClub, Foundamental, EIC Fund, Europa, Saint-Gobain, NetScientific, and 2050 Capital.
