IT Support in London
Managed IT, cyber security and Microsoft 365 support for businesses and charities across London, from an NCSC Assured team trusted since 1996. Fast remote helpdesk, clear fixed pricing and plain-English advice.
IT support for London organisations
ABCOM supports offices, charities and hybrid teams across London. Most issues are fixed remotely by our helpdesk, every ticket is covered by our 2-hour response for critical issues, and our engineers travel up from Burgess Hill for installations, projects and on-site visits when you need them.
London clients get the same senior, NCSC Assured team as our Sussex clients: proactive monitoring, strong cyber security and advice in plain English, without the price tag of a big City provider.

Real feedback from a London client.
"Outstanding service. ALWAYS speedy to resolve issues in a speedy, efficient and calming way (which does help if you're floored by IT as I am). They also work with a large corporate client of mine and cope with all the ongoing demands placed upon them as the business grows apace. Can't recommend enough. So good to know my IT support (and that of my clients) is in safe hands."

Common Questions
Everything you need to know.
Do you provide IT support in London?
Yes. ABCOM supports businesses and charities across London, from the City, Westminster and Canary Wharf to Camden, Southwark and Croydon, with managed IT support, cyber security, Microsoft 365, connectivity and phone systems.
You're based in Sussex. How do you support London offices?
Most IT issues are resolved remotely by our helpdesk, and we respond to every helpdesk ticket within 2 hours, 8am to 6pm, Monday to Friday. For installations, office moves, projects and anything that needs hands on site, our engineers travel up from our Burgess Hill office by arrangement.
Can you support London teams that work from home or several sites?
Yes. We secure and manage laptops wherever your people work, using Microsoft 365, Intune device management and cloud phone systems, so a hybrid or multi-site London team gets the same protection and support as an office-based one.
How much does IT support cost for a London business?
Our Core managed IT support is £65 per user per month, Core Secure, with built-in cyber security, is £89, and Core Assure is from £129 with a minimum monthly fee (all per user per month, excluding VAT). You can get an instant estimate on our Managed IT page.
Can you help my London business get Cyber Essentials?
Yes. We guide you through readiness and certification. The IASME certification fee starts at £320 + VAT, and our readiness help is quoted after a free call. See Cyber Essentials pricing.
What are your contract terms?
Our managed IT agreements: 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.
