IT services for London businesses

Frequently asked questions

Can you actually get an engineer on-site in London?

Yes — we regularly attend client sites across East London and the wider M25 corridor, same-day for urgent issues, alongside remote support for everything that doesn't need someone physically on-site.

What does the free IT health check involve?

A short call to understand your current setup, followed by a no-obligation review flagging any immediate security risks or quick wins — with a clear, jargon-free summary.

We're a small business without an in-house IT team — is that a good fit?

Yes — most of our clients are small and medium-sized businesses without their own IT department. We act as your outsourced IT team, scaled to your size and budget.

Can you take over from our current IT provider?

Yes — we handle onboarding and handover from your existing provider, including documentation and access, with minimal disruption to your team.
