WHAT SME IT SUPPORT COVERS
What IT support for a small business should cover
Small business IT support means one provider looking after everything your team uses to work: the helpdesk your staff call, the security on every laptop and account, Microsoft 365, backup, and the changes when people join or leave. For most SMEs it replaces a mix of a willing colleague, a pay-per-call engineer and a lot of hoping for the best, with one fixed monthly price per user.
It matters because small firms are targets too. In the government’s Cyber Security Breaches Survey 2025/2026, 42% of micro businesses and 46% of small businesses reported a breach or attack in the previous 12 months, and 44% of micro businesses already use an external provider for their cyber security.
- One helpdesk for every problem
- Security on every device and account
- Microsoft 365 managed and backed up
- One fixed price per user
COMMON SME IT PROBLEMS
The IT problems we fix first in small businesses
Most of these build up quietly as a business grows from a handful of people to twenty or fifty. They tend to surface all at once: when someone leaves, when a client sends a security questionnaire, or when a laptop dies the day before a deadline.
One person who “does the IT”
Leavers who keep access
Microsoft 365 that nobody manages
No multi-factor authentication
Paying per call when things break
PCs still on Windows 10
No backup of Microsoft 365
Phones and broadband from separate suppliers
WHAT WE LOOK AFTER
Everything a small business needs, from one supplier
One team for your helpdesk, security, Microsoft 365, devices, backup, phones and connectivity, so there is one number to call and no suppliers blaming each other.
Helpdesk that answers
Unlimited remote support from 9am to 5.30pm on working days, with an average response under 15 minutes and urgent out-of-hours help when you need it. No per-ticket charges, so staff report problems early.

SMALL BUSINESS IT SUPPORT PRICES
How much does IT support cost for a small business?
Managed IT support for a small business costs £30 to £48 per user per month on our Core package, or £55 to £90 per user per month for Complete IT and security. For a team of 15, that is roughly £500 to £700 a month on Core, or £850 to £1,350 a month on Complete. There is a one-off onboarding fee, typically £500 to £2,000, and support runs on a rolling annual agreement.
For comparison, a single in-house IT hire costs upwards of £2,500 a month before employment costs, and one person cannot cover holidays, sickness and every specialism. See how outsourced IT support works.

HOW WE TAKE OVER
Four steps to switch your IT support
Taking over from another provider, or from the person who has been looking after IT alongside their day job, takes around three weeks. A one-off onboarding fee, typically £500 to £2,000, covers auditing, documenting and taking over your systems properly. Moving from another provider? Read how to switch IT support provider.
