IDSL manufactures specialist performance doorsets, such as fire and security doors, for use in hospitals, schools, student accommodation, commercial and residential properties.
Founded in 2016 and based in Mansfield, Nottinghamshire, it operates two manufacturing facilities and employs more than 420 people.
IDSL has a strong reputation for product quality and customer service, and the widest range of performance door intellectual property in the market. This includes ownership of leading brands such as Leaderflush Shapland and Timbmet Door Solutions Limited (TDSL).
The Group also comprises Fire Door Inspection Solutions (FDIS) and Hartland Fire, which both specialise in inspection, maintenance, repair and replacement activities across the UK.
Opening new doors to growth
In May 2024, LDC backed IDSL’s existing management team, led by Founder and Managing Director Ash Malhan, to support the business’ ambitious growth strategy.
LDC’s investment and strategic support is helping IDSL to target further organic growth and complementary acquisitions in a highly fragmented market.
In the first 12 months since LDC’s investment, IDSL saw a 21% increase in turnover to £42.9m, and headcount growth of 47%. In November 2024, the business completed the acquisition of Hartland Fire, a passive fire product and service business.
Deal award
LDC’s investment in IDSL won ‘Medium Deal of the Year’ at the East Midlands Rainmakers Awards 2024. The deal was recognised due to IDSL being a prominent member of the region’s business community.
Our first year with LDC has been defined by real progress – financially, operationally and culturally. LDC’s support and financial backing has enabled us to accelerate our growth strategy, invest in talent and infrastructure, and make headway on our sustainability goals.”
