Outsourced IT support, London
Outsourced IT support means handing the running of your IT to a team outside the business, for a fixed monthly fee. We take on the helpdesk, your Mac and Windows devices, Microsoft 365 and security for London organisations of 10 to 250 people, and we start with a review so you know exactly what you are handing over.
The outsourced IT review
Trusted by teams across UK government, healthcare, education, charities, financial services and global brands
Most organisations do not decide to outsource IT on a quiet day. It usually follows one of these four moments. Each tile shows what changes when the work moves to us.
One person
Your office manager, a founder or a single IT hire looks after everything. Holidays, sickness and a resignation all leave a gap, and nobody else knows the passwords or the set-up.
What changesA team of engineers who share your documentation, so knowledge belongs to your organisation and cover never depends on one diary.
Ad hoc help
A contractor or a friend of the business fixes problems as they appear. Nobody patches, checks backups or plans the next laptop refresh.
What changesMonitoring, patching and backup checks are part of the service, with regular reviews and a roadmap, so fewer issues reach your people at all.
Growth
Laptops are set up by hand, accounts are copied from someone else and leavers keep access longer than they should.
What changesNew starters are ready before their first day and leavers’ access is removed when they go, on Mac and Windows alike.
Due diligence
A security questionnaire lands and nobody can say for certain which laptops are encrypted or who has admin rights.
What changesEncryption, multi-factor authentication and security baselines in place, with reports you can attach to the answer.
Our advice comes from engineers who run these platforms every day. We can share evidence of each on request.

Outsourcing the work does not mean giving away control. This is how responsibility is split once we are running your IT.

Four stages, from the first conversation to a service that improves every quarter. You see the price and the plan before you commit.
The outsourced IT review
We start with a 1-hour call, then review your users, devices, security and cloud set-up. You get a fixed monthly quote and a written view of the risks we found, before you sign anything.
Book an outsourced IT reviewA planned handover
We plan onboarding around your timeline, and on average it takes four weeks. We work with your current provider or IT person to transfer admin access, licences and knowledge, so your staff are not caught in the middle.
Everyday support
Your staff contact our helpdesk by phone, email or the support portal. Engineers fix most issues remotely, and come to your London office when a problem needs hands on equipment.
IT that keeps improving
We meet you regularly to review the service, the risks and what the business needs next. Budgets for devices and licences are planned, not discovered.
Fully outsourced IT suits organisations with no in-house IT team, or where IT has grown beyond what one person can manage. We become your IT department: the people your staff call, the team that keeps devices secure and the adviser at the table when you plan.
If you already employ IT staff, you may not want to hand everything over. Our co-managed IT service, Capacity Creation, adds senior engineers and Apple and Microsoft specialists to your team while your team stays in charge.
Either way, the scope is written down. Our managed IT services page lists everything included, and our switching guide explains how a handover from another provider runs.
Our London team works from Level 24, One Canada Square in Canary Wharf. Remote support is usually the quickest fix, so that is where we start. When the problem is a network cabinet, a meeting room screen or a laptop that will not switch on, an engineer comes to your office.
We are happy to meet before you decide, at our office or yours. For local detail see IT support in Canary Wharf and IT support across London.

Outsourced IT support is when an external team runs some or all of your IT for a regular fee. With us, that covers the helpdesk, Mac and Windows devices, Microsoft 365 and security. You keep ownership of your accounts and data, and you get one team that is accountable for all of it.
Our managed service is priced from £25 per device per month, excluding VAT and licences. The agreement normally runs for two years, with a one-year minimum. After the outsourced IT review we give you a fixed monthly quote. See IT support pricing.
It depends on your size and what you need, so we will not promise a saving. What changes is cover and breadth: a team covers holidays and sickness, and brings Apple, Microsoft and security skills that one hire rarely has. The review gives you the figures to compare.
If you have an IT person, many organisations keep them and use our co-managed service alongside. If you have a provider, we work with them during the handover to transfer access and knowledge, and we follow your notice period.
No. Your Microsoft 365 tenant, Apple Business account, Jamf instance, domains and data stay yours. We use delegated admin access and document everything, so you can see what we do and could move to another provider.
Yes. We are a Jamf Professional Partner and Jamf MSP, and a UK Microsoft Cloud Solution Provider. One team manages Mac, iPhone, iPad, Windows and Microsoft 365. See Mac IT support.
Start with a 1-hour call. We will ask how your IT runs today, tell you honestly whether outsourcing to us makes sense, and show you the price before you commit.
