What matters for IT in London
We are a Sussex team supporting London clients, and we would rather say so up front. Here is where that works well.
Hybrid teams
If your people split the week between a London desk and home, most of your IT problems can be fixed remotely. What they need is a helpdesk that answers, and that matters more than an engineer down the road.
Microsoft 365 supportSecurity questionnaires
If you sell to larger companies or the public sector, you may be asked for proof of your security. We guide you through Cyber Essentials, and can carry out testing if a customer asks for more.
Cyber EssentialsA price you can see
Managed support starts at £65 per user per month, and we publish what is included and what is quoted separately. You can work out a rough figure on this page before you speak to anyone.

Can you support London teams that work from home or several sites?

Our prices are published, so you can check for yourself. Managed IT support starts at £65 per user per month, excluding VAT, which you can set against your current bill.
