We work with small businesses across various sectors, including retail, hospitality, legal, creative, construction, architecture and more. If your business relies on technology (and whose doesn't?), we’re here to ensure it runs smoothly.

Nearly all of our services are available remotely, from troubleshooting and fixing software issues to setting up new systems and managing cybersecurity. With our remote support, it’s like having an IT department on hand, no matter where you are.

We take security very seriously. From antivirus solutions to network monitoring and patch management, we have a multi-layered approach that keeps your business protected from a wide range of cyber threats. We also offer advice and training to ensure your team follows best practices.

Our official office hours are 09:00 to 17:00, Monday to Friday.

However, IT issues can arise at any time, so we’re often available beyond regular hours. We can arrange out-of-hours support, including weekends and evenings. This is particularly helpful when minimising disruption is crucial for your business.

Best of all, we don’t charge extra for out-of-hours work—it’s all part of our commitment to providing fast and friendly support when you need it most.

We primarily serve East Sussex, West Sussex, Kent, Surrey, and London for on-site support. However, our remote support means distance isn’t a limitation—wherever you are, we’ve got you covered. We currently support clients with remote workers spread as far West as Plymouth, East to Margate and the East Kent Coast, and even internationally, including their staff in Spain.

Fun fact: A few years ago, one of our clients worked temporarily from Vietnam, and with a little time zone coordination, we ensured they stayed fully supported. So, whether you’re down the road or across the globe, we’re here to help.

Yes, we do. We understand that IT issues can be urgent, and our fast response times are designed to get your business back up and running as quickly as possible. Contact us for more information on how we handle emergencies.

Absolutely. We’re not just here to fix problems—we’re here to help you plan for the future. Our IT consultation services can help you streamline your technology, improve productivity, and prepare for growth, all with a strategic perspective.

Yes, we have extensive experience with cloud solutions, including Microsoft 365. Whether you’re looking to move email, documents, or set up collaborative tools, we can help you transition smoothly and securely to the cloud.

Our goal is to provide fast and friendly support. During our office hours (09:00 to 17:00), we aim to respond to urgent IT issues within an hour.

For non-urgent matters, we work to be in touch the same day during business hours. We understand how costly downtime can be for your business, so our priority is to get you back up and running as quickly as possible.
