What Antac does

Antac Support Services Limited is a privately held UK facilities management company founded in 2001 and headquartered in High Wycombe, Buckinghamshire. It delivers a multi-disciplinary portfolio of support services through six core divisions: Projects (building and small works), Building Maintenance (mechanical, electrical, HVAC, planned preventative maintenance), Void Housing (MoD Service Family Accommodation maintenance), Window Cleaning (the UK's largest independent national window cleaning operation with a fleet of over 100 vehicles), Rope Access (IRATA-certified cleaning and maintenance at height), and Cleaning Services (commercial, industrial, and specialist cleaning including a newer solar panel cleaning offering). The company operates with 500+ directly employed staff, holds a stack of compliance credentials (ISO 9001/14001/45001/50001, Constructionline Gold, IRATA, IPAF, Q-Mark), and runs an internal PULSE workforce field management platform to dispatch jobs, capture risk assessments, and record customer sign-off.

The company serves government, healthcare, corporate, education, and heritage customers across the UK, with notable anchors including the Ministry of Defence (Service Family Accommodation portfolio of 10,000+ homes via Vivo Defence Services and the FDIS contract with Vinci Facilities), NHS hospital trusts (Barts Health, Sheffield Teaching), BMI Healthcare across 62 sites, EE, Bullring Shopping Centre, and Softcat. Antac reports 521+ happy customers, 2 million windows cleaned, 4,500 LED light fittings upgraded, and 64 office refurbishments completed, alongside recognition including MoD Employer Recognition Scheme Gold Award (2023, 2024) and consecutive Southern Enterprise Awards.

The revenue model is predominantly managed services (ongoing maintenance contracts with recurring scheduled and responsive work) supplemented by professional services revenue from one-off projects and refurbishments. Pricing is bespoke and quote-based, with no public rate cards, and contracts are structured as multi-year enterprise agreements. GTM is direct enterprise and government field sales through dedicated account management, supported by a national fleet, 24/7 central help desk, and a content-driven B2B marketing approach across website, social, brochures, and industry PR. The company remains founder-led by Managing Director Stephen Burton (24 years) with no disclosed external investment, acquisitions, or restructuring events.

Broad incumbents

• Serco Group: UK-listed public-service outsourcing company with significant UK defence, healthcare and justice portfolios. Comparable to Antac in MoD/NHS contract exposure and framework-driven revenue, though much larger and more diversified across non-FM services.
• ISS A/S: Global facility services provider with UK operations across cleaning, workplace, technical and property services. Comparable to Antac in core service mix (cleaning, maintenance, support services) but operates as a global incumbent at much larger scale.
• Mitie: Largest UK-listed facilities management and professional services company, offering a much broader portfolio across security, engineering, cleaning and connected workplace. Comparable to Antac as a UK FM incumbent serving public-sector and enterprise clients, though materially larger.
• Sodexo UK: Global food services and FM operator with UK presence across corporate, healthcare, education and defence segments. Comparable to Antac in healthcare, MoD and corporate vertical exposure but at vastly greater scale and global breadth.

Direct peers

• Churchill Group: UK-based independent integrated facilities services provider offering cleaning, security, maintenance and front-of-house services to enterprise and public-sector clients. Closely comparable to Antac in scope (multi-service FM), independent ownership profile, and UK mid-market positioning.
• OCS Group: Independent UK FM group delivering cleaning, security, catering and maintenance services nationally to public and private sector clients. Comparable to Antac as a privately held, UK-domestic, multi-trade FM operator with similar customer verticals.
• Pareto FM: UK independent facilities management company providing building maintenance, cleaning, security and grounds services to commercial and public-sector clients. Directly comparable to Antac's six-division, multi-trade service offering.
