3aIT was established in 1999. Ever since then, we have continually supported businesses through a combination of telephone and remote support, routine maintenance and rapid response callout.

When a system crashes or the internet connection goes down, you need an instant response. Our IT Support Helpdesk Engineers are knowledgeable, helpful and patient – quite used to talking the uninitiated through a series of steps that will restore normality.

Routine maintenance has a proven track record in reducing such system failures, downtime and IT costs. The majority of costly emergency call-outs can be pre-empted by checkups that catch the disasters before they occur.

We can meet the IT Support needs of your company with flexibility and cost efficiency. We can assist in maximising the productivity of the IT infrastructure, while reducing the total cost of ownership.

While our main office is based in Horsham, we can provide onsite support to many areas throughout the south-east including Crawley, Littlehampton, Worthing and Chichester, and many other areas, including those listed in the sub menu to the right / below. We also now have many support clients dotted around London.
