Managed IT Support
What does an IT support company actually do for a business? A typical week, explained
What an IT support company does day to day for a UK business: helpdesk, monitoring, patching, security, Microsoft 365, backup and networks, as a typical week.

Short answer
An IT support company keeps a business's computers, servers, network, Microsoft 365, security and backups working and secure. Day to day that means a helpdesk for staff, monitoring and patching every device, managing endpoint and email security, checking backups, setting up joiners and removing leavers, maintaining the network, and advising on what to buy and change next.
Business owners who have never had a support contract tend to picture someone who turns up when the printer breaks. That happens, but it is a small fraction of the work. The rest is scheduled, quiet and preventive, and it is the reason clients with good support rarely see their provider. This article sets out the eight areas an IT support company covers and then shows what they look like across a typical week.
The eight areas
1. Helpdesk
The visible part. Staff log problems by phone, email or portal: cannot print, mailbox full, file missing from SharePoint, Outlook wants a password, laptop slow, VPN will not connect. Tickets are prioritised and resolved, most remotely using a tool such as Splashtop, some on site. Ticket history is reviewed for recurring problems that need a root-cause fix. See IT helpdesk.
2. Monitoring and maintenance
Remote monitoring and management (RMM) agents on every computer and server report health continuously: disk space, failed services, pending updates, backup status, hardware warnings. Engineers review the alert queue each morning and fix what needs fixing, usually before anyone has noticed. Patches for Windows, browsers, Office and network firmware are tested and applied on a schedule, out of hours. See proactive monitoring.
3. Security
Managed endpoint detection and response (EDR) on every device. Email filtering. Multi-factor authentication enforced. Access reviewed. Staff trained and tested with simulated phishing. Vulnerabilities scanned for. Cyber Essentials assessments supported. When something gets through, an incident response: isolate, investigate, restore, report. See cyber security.
4. Microsoft 365 and cloud
User accounts, licences, mailboxes, SharePoint and Teams permissions, retention, MFA and conditional access. Migrations from on-premises servers. Backup of Microsoft 365 data, which Microsoft's own shared responsibility model leaves with you. See Microsoft 365 services.
5. Backup and recovery
Backups configured, monitored daily, and restore-tested on a schedule. Local and cloud copies. A documented recovery procedure so that when a server fails or ransomware hits, the steps are known and the time to recover is understood in advance.
6. Network and infrastructure
Firewalls, switches, Wi-Fi access points and cabling installed, configured and kept on supported firmware. Guest Wi-Fi separated from business systems. Site-to-site VPNs for multi-site businesses. Structured cabling and fibre for new offices. CCTV on the same managed network where wanted. See IT infrastructure and networking.
7. Joiners, leavers and hardware
New starters: account, licence, laptop built to a standard, MFA enrolled, access granted, all before day one. Leavers: access removed the day they go, mailbox handled, device recovered. Hardware procured from HP or Dell under warranty, tracked in an inventory, replaced on a planned cycle.
8. Advice and planning
Account reviews a few times a year. What is out of warranty, what is at risk, what to budget for. Advice on cloud moves, office relocations, phone systems ahead of the PSTN switch-off, and growth. See IT consultancy.
A typical week
The best way to understand the job is to watch it. Here is a composite week for a provider looking after a 30-person client with one office, a server and Microsoft 365.
Monday. Morning alert review: one laptop reporting a failing disk, replaced under warranty before it dies. Weekend patch cycle checked, two machines that missed it are rescheduled. Helpdesk: a new starter's laptop delivered and enrolled, a user locked out after too many MFA attempts, a shared mailbox permission change. Backup report reviewed, all jobs green.
Tuesday. Helpdesk: printer offline for a department, resolved remotely by restarting the print spooler and noted as the third occurrence this quarter, so a firmware update is scheduled. A phishing email reported by a member of staff, sender blocked, message removed from all mailboxes, user thanked. Monthly restore test: a folder restored from last Thursday's backup in eleven minutes, logged.
Wednesday. On-site visit: firmware update on the printer, a Wi-Fi access point relocated after complaints about a dead spot in the meeting room, a director's docking station replaced. While there, a quick look in the comms cabinet turns up a switch port with a loose cable, fixed. Leaver processed: account disabled, mailbox converted to shared for the manager, laptop collected for rebuild.
Thursday. Licence reconciliation: three Microsoft 365 licences assigned to leavers from last quarter, released, saving the client their monthly cost. Helpdesk: Teams call quality complaint traced to a home broadband issue, user advised. EDR console reviewed, one alert investigated and confirmed benign. Quarterly review prepared: two servers approaching end of warranty, a recommendation to retire one into Microsoft 365.
Friday. Quarterly review meeting with the client's operations director: findings, hardware plan, a conversation about a second office next year. Helpdesk quiet. Patch cycle scheduled for the weekend, including the firewall. Documentation updated with the week's changes.
Across the week, the client saw perhaps six of those items. The rest happened without them, which is the point.
What it does not do
An IT support company does not write or fix your line-of-business software, though it will liaise with the vendor and own the escalation. It does not decide your data protection policy, though it will implement it and produce the evidence. It does not replace the need for a director to own IT decisions, though it will make those decisions much easier. And unless the contract says so, it does not provide out-of-hours cover, projects or hardware for free. All of that should be in the inclusions and exclusions, as what is managed IT support? explains.
What it costs
Most of the above is delivered under a monthly contract priced per user or per device. Our indicative per-device rates are £17.50 per computer, £16.50 per desk phone with the line included, £10 per network printer, £25 per router or firewall and £150 per server per month (figures reviewed October 2026, confirmed in a written quote). For the 30-person client in the example, with a server, a firewall and two printers, that is about £720 a month before phones. The IT support cost calculator will run the figures for your own setup, and how much IT support costs in the UK explains what moves the price.
What to do next
If your current arrangement covers the helpdesk but little of the rest, an IT health check will show which of the eight areas are being managed and which are not, and what the gaps are costing you in risk. It is the same assessment we run in the first month with a new client.
