Questions
Frequently asked questions
How quickly can you respond?
We aim to respond to every enquiry the same working day, and often within a few hours. Essential includes business-hours remote support. Complete receives priority remote support, and fair-use onsite visits in the coverage area. We do not run a 24-hour helpdesk. If something is urgent during our support hours, we arrange remote help or an onsite visit as quickly as the situation allows.
Do I need a monthly contract?
No. Pay As You Go has no contract: remote support is £75/hour, billed in 15-minute blocks with a 30-minute minimum, and an onsite call-out is £95 including travel and the first hour. If you would rather have regular support, Essential and Complete are rolling monthly contracts with no lock-in, at a minimum of £105/month (3 users).
What is the difference between Essential and Complete?
Essential is £35 per user/month and covers business-hours remote support and basic Microsoft 365 administration, on a fair-use basis.

Both. Many Microsoft 365, security and helpdesk issues are resolved remotely. For hardware, networking, printers, EPOS and office visits, we come onsite. Pay As You Go onsite call-outs are £95 including travel and the first hour, then £75/hour. Complete contracts include fair-use onsite visits in the coverage area.

What happens in a free IT health check?
We review your current setup — devices, Microsoft 365, security, backups and network — talk through any issues, and give you a clear, no-obligation recommendation. It is a conversation, not a hard sell.
