He's incredibly patient with me and all of my ideas 😂, really listens to what I want, and somehow manages to bring it all together. I couldn't recommend him highly enough!

We Don’t Just Sell ItWe Support the Business Around It
Most people who buy hardware from us never find out that the same team runs managed IT, cloud and security for UK businesses. That side is contracted work rather than a one-off call-out — so if you are fitting out a company rather than replacing a single laptop, it is worth a conversation.

Monitoring, patching and an SLA-backed helpdesk under a monthly contract. Remote first, with on-site support where the contract provides for it.

Hardening, firewall management and vulnerability scanning — plus Cyber Essentials certification support. We are certified ourselves.

Microsoft 365 and Azure provisioning, migration and management, with hybrid architecture where keeping hardware on site makes sense.

IT strategy, infrastructure reviews, procurement strategy and project management — the work that decides what to buy, and in what order, before anyone buys it.
