Meet the most helpful IT team in town

Looking for a long-term IT partner? Choose one that does more than solve problems. We work with you to improve your IT over time.

Your staff are not all IT enthusiasts like us, so we keep it simple whenever we talk tech.

  • Filling knowledge gaps. When people are struggling with a tool, we take the time to show them how it works.
  • Tackling repeat issues. If several people report the same problem, we change the system rather than patching it again.
  • Proactive maintenance. We monitor your systems for early warning signs of failure or slowdown.

Fast response times

Few things are more frustrating than waiting hours for IT help in the middle of a busy day. So we make help quick, reliable and on demand.

Always ready for your call

Our team is structured so your call is answered quickly. You get a dedicated account manager you can contact directly with any request.

Instant fixes from our helpdesk

Our remote support and monitoring tools let us fix many issues straight away, from "Outlook isn't working properly" to wider network problems.

Engineers on site, fast

When you need us in person, we can be there in as little as 40 minutes, sooner for top-priority issues. Visiting also helps us get to know your team.

IT that evolves with your business

Outdated or fragmented systems cause communication breakdowns between teams, which means frustrated staff, lost data and other headaches.

We work with your key stakeholders to build a practical IT roadmap, so you are ready for what comes next without disrupting day-to-day work.

Smoother hybrid and remote working

We use cloud tools so your teams can work effectively wherever they are. With Microsoft Teams, Google Meet, Zoom and our sister company Phones 21, your people can collaborate from anywhere.

Support plans

Every plan includes full system monitoring and a device security package. Pricing depends on team size and requirements, so call us or book a consultation for a quote.

IT Support Silver

Core monitored support for smaller teams.

IT Support Gold

Our fully managed plan, with proactive improvements built in.

Bespoke or ad hoc

Project work or support charged as you use it.

Client success stories

Portner Law: improving security for a London law firm

Within three months of supporting Portner, we moved their outdated systems to the cloud, raised their score on a third-party penetration test by 80%, digitised their phone system, rolled out company-wide two-factor authentication and encryption, and deployed a modern backup suite.

Their team can now work securely from anywhere, accessing files and taking calls on their office numbers from laptops or mobiles, with Microsoft Teams keeping departments connected.

Hotspex: solving remote working issues

Hotspex is a market research company headquartered in Toronto, with a UK team that relied on IT support from Canada. We started as an extension of their Canadian IT team, acting as their eyes and ears on the ground.

The UK team struggled with a document archive hosted in Canada, so we implemented a local UK server mirroring it, improving read and write speeds by 100x. Their internal IT team no longer manages it remotely and can focus on other priorities.
