Our Story

Why we started Sentinel

We kept seeing local businesses poorly served by IT providers that were either too large to care or too small to cope, and Sentinel Infrastructure grew out of that frustration. The idea was a local IT partner with enterprise-level expertise, run by a team that responds quickly and genuinely wants your business to succeed.

Our remote helpdesk supports businesses across the UK, and we come on-site when it's needed. We get to know each business and its sector, including the IT problems it deals with every day.

Our view is that a small business should be able to expect IT that just works, the same as a large one. For us, that means hosting that stays up, email that's set up properly, problems picked up early, and a person to speak to when something does go wrong.

Why Sentinel

Four reasons businesses choose us

Personal Service

We understand how SMEs work, and we know every client by name rather than by ticket number.

Fewer Suppliers to Chase

We can manage your domain, hosting, maintenance, IT support and Microsoft 365 together. When something breaks, nobody has to work out which supplier to ring first.

Fixed, Predictable Pricing

Our monthly plans spell out what's included and what it costs, with no surprise charges on top. Budgeting is straightforward, and you can scale up as your business grows.

Proactive by Default

We keep your systems monitored and regularly patched, and planned reviews help us spot anything likely to cause trouble later on.
