What HYDROSPEC LIMITED does

Hydrospec Limited is a UK specialist commercial swimming pool engineering contractor founded in 1988 and headquartered in Brentwood, Essex. The company delivers refurbishment, plant room upgrades, filtration, chemical water treatment, mechanical and electrical systems, and energy-efficiency solutions exclusively to commercial and public-sector clients — councils, schools, leisure operators, heritage sites and main contractors. Service delivery combines mechanical, electrical and civil engineering expertise with specialist water treatment and filtration knowledge, under a "right-first-time, zero-defect" methodology that emphasises pre-survey, detailed design and phased installation to minimise facility downtime.

The firm operates with a small team of approximately ten employees and runs a project-based contracting model, with individual project values disclosed in the £1m–£4.7m range. Its service portfolio spans eight core offerings: project management and design-build, filtration and chemical water treatment, M&E and energy efficiency, specialist hydrotherapy pools for SEN and healthcare, commercial pool refurbishment, heritage pool refurbishment, condition surveys and consultancy, and planned preventative maintenance. Hydrospec holds SafeContractor, SSIP and PWTAG accreditations, is working towards ISO 9001, and has won the UK Pool & Spa Awards five times between 2019 and 2025. Geographic focus is London, the South East and the wider UK.
