Why it matters

Sussex businesses deserve
IT support that gets them.

We're based in Cranleigh on the Surrey/Sussex border — which means Sussex businesses get the same fast, local service as our Surrey clients. When something goes wrong, you want someone who can be on-site in Horsham or Crawley quickly, not on the other end of a national helpline.

We've been supporting businesses across Surrey and Sussex since 1992. The South-East is our patch — we know its businesses, its industries, and what matters to growing companies here.

And when we can't fix something remotely, we're close enough to get there fast.

Common questions

Questions about
IT support in Sussex.

Things Sussex businesses typically ask before getting in touch.

Do you cover all of Sussex?

Yes. We support businesses across East and West Sussex — including Brighton, Horsham, Crawley, Chichester, Eastbourne, Haywards Heath and surrounding areas. Most support is handled remotely, with on-site visits when needed.

How quickly can you get to us on-site?

For most of Sussex, we can be on-site within a couple of hours for urgent issues. We'll always try to resolve things remotely first — it's faster for everyone — but when you need us there in person, we'll come.

What size businesses do you work with?

We specialise in businesses with 5 to 50 employees — typically owner-managed businesses, professional services firms and growing SMEs. If you're in that range and don't have dedicated in-house IT, we're likely a good fit.

How long does it take to switch to ISS?

A well-managed switch typically takes around four weeks from first conversation to go-live. We handle the process — including the handover from your existing provider — so there's minimal disruption to your team.

Do you offer fixed-price contracts?

Yes. All our packages are fixed monthly pricing based on the number of users. No hidden extras, no surprise invoices. You know exactly what you're paying before you sign anything, and we work on 90-day rolling agreements.

Can you help with Cyber Essentials?

Yes. We help businesses across Sussex achieve Cyber Essentials certification — particularly useful if you're tendering for contracts or want to demonstrate good security practice to clients and stakeholders.

Do you work with businesses that have remote or hybrid teams?

Yes, fully. We support businesses with office, remote and hybrid workers. Our tools work across locations and devices, and your team can reach our helpdesk by phone, email or portal from anywhere in Sussex or further afield.
