Your IT Support Partner in West Sussex
Little Big Tech provides managed IT support to businesses across West Sussex — from Crawley's commercial centre and Gatwick's logistics cluster through to the professional services firms in Horsham, Haywards Heath, and Chichester, and the healthcare and leisure businesses along the coast. When something goes wrong, you speak to engineers who know the area — not a call centre reading from a script.
West Sussex businesses often operate across dispersed locations — a head office in Crawley, a branch in Horsham, staff working from Worthing or Bognor Regis, or a team split between office and home. We build IT environments for that reality: consistent security policies regardless of where your people are working, reliable remote access, and helpdesk support that scales with you rather than fighting against you.
Every West Sussex client starts with a Technology Resilience Score™ — a benchmarked measure of your ability to prevent, withstand and recover from technology and cyber risks, on a scale of 1 to 5. Most organisations of similar size and complexity operate at 3.5 or above. Most businesses we assess start below that. Knowing where you sit against that benchmark is the fastest way to see where targeted investment strengthens your resilience most. Our onboarding plan is built to lift your score above 3.0 within the first 90 days.
Our 24/7 Security Operations Centre monitors your environment around the clock — cyber attacks don't keep office hours, so neither does your defence. Alongside that, our helpdesk is available Monday to Friday, 8am–6pm, staffed by engineers who handle IT support without scripts or ticket-queue delays. We also run regular phishing simulations and vulnerability assessments, which matter particularly for West Sussex businesses in professional services, legal, and healthcare sectors where client data is the primary target.
West Sussex has a genuinely varied economy: one of the UK's busiest logistics and aviation clusters around Gatwick and Crawley; a strong professional services and legal community in Horsham and Haywards Heath; private healthcare and cosmetic practices across Chichester and the coastal towns; and a mix of manufacturing, retail, and growing SMEs from Worthing to Bognor Regis and Littlehampton. We support businesses across all of those sectors and towns: Crawley, Horsham, Haywards Heath, Chichester, Worthing, Bognor Regis, Burgess Hill, East Grinstead, Littlehampton, Shoreham-by-Sea, Lancing, Arundel and beyond.
If your business operates in a regulated sector — legal, financial services, or private healthcare — we align your IT environment with the compliance frameworks that apply to you: SRA for law firms, FCA operational resilience for financial services, CQC readiness for healthcare providers. The TRS framework covers these compliance dimensions directly, so you get a clear measure of where you stand, not a vague audit report.
