One IT technician costs more than you might think, and still can’t cover holidays, sickness or every specialist skill.
- A team, not one person, so there’s always cover
- Security, Microsoft 365 and networking specialists included
- Monitoring and patching around the clock
- No recruitment, training or management overhead

Already have an IT person?
Many organisations keep someone in-house for day-to-day needs and use ABCOM for the rest: specialist skills, cyber security, holiday cover and our monitoring tools.
You keep the local knowledge; they get a team behind them.

Managed IT services FAQs
How much do managed IT services cost?
ABCOM Core managed IT support is £65 per user per month, and Core Secure, which adds vulnerability monitoring, security baselines and monthly security reporting, is £89 per user per month. Core Assure starts from £129 per user per month and has a minimum monthly fee (all excluding VAT). For example, a 20-person business on Core pays £1,300 a month. Use our instant estimator for a quick figure.
What is included in managed IT support?
Unlimited remote helpdesk support, proactive monitoring and maintenance, patching of operating systems and key applications, Microsoft 365 support, managed antivirus and endpoint protection, and managed backups. Standard Microsoft 365 backup is included on every plan. Core Secure adds continuous vulnerability monitoring, a security baseline, Cyber Essentials-aligned controls and monthly security reporting. Core Assure adds out-of-hours incident support, incident rehearsal, a monthly DMARC review and Intune device management.
How fast do you respond?
Our SLA commits to responding to critical issues within 2 hours, with response targets for every ticket by priority. Tickets are handled as they come in, and the most severe issues, such as the whole business being unable to work, are prioritised first. Our support desk is open 8am to 6pm, Monday to Friday.
Do you provide onsite IT support?
Yes. Most issues are fixed remotely because it is fastest, but our engineers visit sites across Sussex for hardware, network installations, office moves and anything that needs hands-on work. Remote helpdesk support is included. On-site visits are charged at £80 per hour, with no call-out charge for clients under contract. Core Secure has a discounted rate, and Core Assure includes free on-site visits for critical issues in Mid Sussex.
What is the contract term?
You can start on a 90-day agreement (onboarding is a one-off fee) or choose a 12-month term, which includes free onboarding, a Technical Account Manager and, on Core Secure and Core Assure, a quarterly vCISO review. Notice is 1 month, effective no earlier than day 90, or after the first 12 months on a 12-month term. Any remediation of issues found at onboarding, such as an outdated server, is quoted separately.
Is Microsoft 365 backup included?
Yes. Standard Microsoft 365 backup is included for every supported user on all plans. Server, PC image and disaster recovery backup are scoped and quoted separately.
Core, Core Secure or Core Assure?
Core gives you reliable, fully managed IT support. Core Secure includes everything in Core plus built-in cyber resilience: continuous vulnerability monitoring, a security baseline configuration, controls aligned with Cyber Essentials and monthly security reporting. Core Assure adds out-of-hours incident support, incident rehearsal, a monthly DMARC review and Intune device management, with free on-site visits for critical issues in Mid Sussex. Cyber insurance and most compliance frameworks typically need Core Secure or above.
Can you work with our in-house IT?
Yes. Many organisations keep an internal IT person for day-to-day needs and use ABCOM for specialist skills, cyber security, cover during holidays and our monitoring tools. We call this co-managed IT.
Cheaper than hiring IT staff?
Often, yes. A single IT technician on £28,500 costs around £32,700 a year once employer’s National Insurance and pension are added, while ABCOM Core for 20 users is £15,600 a year excluding VAT, and gives you a whole team with cover for holidays and sickness.
Do you cover Brighton and Sussex?
Yes. From our base in Burgess Hill, we support businesses and charities in Brighton and Hove, Haywards Heath, Crawley, Horsham, Lewes, Worthing, Chichester and across Sussex, with remote support and onsite visits.
How do we switch provider?
We run a structured onboarding: a review of your systems, a professional handover from your current provider, a site visit, then securing admin accounts and backups and deploying our monitoring and security tools, usually with no downtime.
Is your support available 24/7?
Our service desk has a 2-hour response for critical issues during business hours (8am to 6pm, Monday to Friday). Our endpoint detection and response (EDR) software runs 24/7 on every protected device, and it is monitored around the clock by a security operations centre (SOC).
What do EDR, SOC, NOC and ITDR mean?
EDR (endpoint detection and response) is security software on each laptop, desktop and server that watches for signs of an attack and can isolate an infected device. A SOC (security operations centre) is the team of analysts who investigate those alerts around the clock. A NOC (network operations centre) monitors the health and availability of networks, servers and devices, so it keeps systems running rather than hunting attackers. ITDR (identity threat detection and response) is the identity side of the same idea: it looks for signs that a Microsoft 365 account has been taken over, such as logins from unusual places or suspicious mailbox rules. Microsoft includes identity protection features in its premium plans.
