London-wide IT support
We support organisations across central and Greater London. Your staff contact our helpdesk by phone, email or the support portal. An engineer who knows your set-up answers.
We fix most issues remotely, on Mac and Windows. When a problem needs someone in the room, we send an engineer to your office. This includes hardware faults, network problems, meeting rooms, new equipment and office moves.
Some clients prefer a planned on-site day each week or each month. We can include this in your service agreement.
- Helpdesk by phone, email and support portal
- Remote sessions on Mac and Windows
- On-site visits across London when needed
- Planned on-site days by agreement
- New starters, leavers and equipment
- Office moves, networks and Wi-Fi
Our office is in One Canada Square
If your office is in Canary Wharf or elsewhere in E14, we are close by. Our Canary Wharf page covers local support, serviced offices, office moves in the estate and IT for regulated businesses.

How on-site visits work
Every visit starts with a ticket, so we track your request from start to finish.
- Step 1
Log the issue
Your staff contact the helpdesk by phone, email or the portal. We record the issue and set its priority.
- Step 2
Try remote first
An engineer connects remotely where possible. We fix many issues at this stage.
- Step 3
Visit and fix
If the issue needs hands on equipment, we book a visit and confirm the time with you. The engineer arrives with your documentation and the ticket history.
- Step 4
Close and record
We update the ticket and your documentation. If the issue could happen again, we plan a permanent fix.
What helps a visit go well
Building access is a common cause of delay. Some preparation means the engineer can start work as soon as they arrive.
We keep building access notes, comms room locations and supplier contacts in your documentation. We update them after every visit.
- A named contact at your office for each visit
- Building access and visitor passes arranged in advance
- Access to the comms room and network cabinet
- Details of your landlord or building IT contact
- Spare devices stored in a known, secure place

Co-managed IT for in-house teams
Capacity Creation adds senior engineers and specialist skills to your own IT team. Your team stays in control. See co-managed IT.
A small senior team
You speak to experienced engineers who know your environment. We document everything, so knowledge stays with your organisation.
London and Dubai offices
If you operate in the UK and the UAE, one provider can support both. We support the wider GCC and the US remotely.
Security as standard
We set up and run multi-factor authentication, encryption, patching and security monitoring as part of the service, using the security tools in your licences.

Frequently asked questions
Can’t see your question? Call us on +44 20 7550 9103 or book a call.
Do you provide on-site IT support across London?
Yes. Our engineers visit offices across central and Greater London from our office in Canary Wharf. We fix most issues remotely first, because that is usually the quickest fix for your people, and send an engineer when a problem needs hands on, such as a new starter set-up, a faulty device or an office move.
Where is your London office?
Our office is at Level 24, One Canada Square, Canary Wharf, London E14 5AB, and it is open Monday to Friday, 9am to 6pm. We can meet you there or at your office, whichever suits you better. If you are in Canary Wharf, see our IT support Canary Wharf page.
Do you support Mac and Windows?
Yes. Apple and Microsoft are our two specialisms. We are a Jamf Professional Partner, and we manage Windows with Microsoft Intune. One team manages both platforms. See Mac IT support and Windows IT support. For iPhones and iPads as well as Macs, see Apple IT support in London.
What types of organisations do you support in London?
We support organisations of different sizes and sectors across London. They include government departments, the NHS, financial services organisations, legal practices, charities, universities and Mac-first technology teams. Many run Macs and Windows side by side, and need to show clients, insurers or regulators that their IT is under control.
Do you provide IT consultancy as well as support?
Yes. Our IT consultancy covers strategy, audits and reviews, and we plan and deliver projects such as Entra ID migrations, Jamf and Intune roll-outs and Microsoft 365 health checks. You can use us for advice or projects only, or for projects and ongoing support, with the same engineers involved throughout.
Can you work alongside our in-house IT team?
Yes. Our co-managed IT service, Capacity Creation, adds senior engineers and specialist skills to your in-house team, for example third-line escalation, Jamf and Intune expertise, project capacity or holiday cover. Your team keeps ownership and control of your systems, and we agree with you who handles what.
Can you help us get Cyber Essentials?
Yes. We prepare your Macs, PCs, phones, accounts and network for the Cyber Essentials requirements and fix the gaps we find. We then support you through the assessment with a certification body licensed by IASME. We hold Cyber Essentials and Cyber Essentials Plus ourselves. See Cyber Essentials.
Can you supply our Microsoft 365 licences?
Yes. We are a UK Microsoft Cloud Solution Provider (CSP). We supply Microsoft 365 licences alongside your support and advise on the right plan for each user. We review your current licences first, so you pay only for what you use and switch on the security you already own. See Microsoft 365 licensing.
How long does onboarding take?
We plan onboarding around your timeline and run it as a project with agreed dates. On average, it takes four weeks from the first call. By the end, we hold admin access, your devices are enrolled into Jamf and Intune, your environment is documented, monitoring is live and your staff use our helpdesk.
Do you support organisations outside London?
Yes. We support organisations across the UK remotely, with the same helpdesk, device management and reviews as our London clients, and clients in the US remotely. We also have an office in Dubai, where we support the UAE on site and the wider GCC remotely. See IT support Dubai.
