A single named account director, a 24/7 UK-based service desk, and a registered office on City Road. We support mid-market businesses across London and the South East.
Founded 2010, grown from £10m to £31m • 2,500+ UK businesses served • ISO 27001, ISO 9001 & Cyber Essentials Plus certified
London is home to a lot of mid-market businesses who've outgrown the local one-person IT contractor but don't want to disappear into an enterprise supplier's account list. That's why we built Highgate: for organisations with 100 to 2,000 people, usually £10m to £250m in revenue, who need control over risk, predictable costs, and a partner who answers the phone.
We're not the biggest name in London IT. We're a national managed service provider with a registered London office, a genuinely remote delivery model, and one account director who owns your relationship.

Three sectors are consistently well represented among our London clients. Each has its own compliance pressures and its own reasons for switching IT partner.
Chartered accountancies, financial planning practices and wealth managers, many in and around the City. FCA alignment and audit-readiness come as standard, not an add-on.
Law firms and professional practices where client confidentiality and uptime aren't negotiable, and a security incident is a reputational event, not just a technical one.
Schools, trusts and training providers across London balancing tight budgets against safeguarding and data protection obligations.
Every engagement sits under one of three outcomes. Most clients start with cybersecurity or managed services, then expand.
Gap analysis, Cyber Essentials Plus, SOC-as-a-Service, phishing simulation and incident response.
Disaster recovery, backup-as-a-service, and business continuity planning that gets tested, not just written down.
Cloud migration, IaaS, cost optimisation and infrastructure health checks.
24/7 service desk, platform monitoring, and proactive maintenance under one account director.
SD-WAN, wireless networking, and UCaaS for teams working across multiple London sites.
Device-as-a-service, Microsoft 365, Copilot rollout and JML services for growing headcounts.
Highgate has supplied IT hardware and software since 2010, vendor-agnostic and account-managed by the same team that runs your IT. Buy alongside a managed service, or on its own.
– Microsoft Modern Management rolled out across all four offices
– Single account director replacing a fragmented, office-by-office support model

Our registered office is at 124 City Road, EC1V. It’s a virtual registered address, not a staffed site, in keeping with our all-remote delivery model. What you get instead is a named account director for your relationship and a 24/7 UK-based service desk, so support isn’t limited by who’s in a building on a given day.
Central London, the City, and boroughs across Greater London, plus the wider South East. Most of our current London clients sit in financial services, legal and professional services, or education.
Mid-market: usually 100 to 2,000 employees and £10m to £250m in revenue. We’re not set up for micro-businesses wanting occasional support, and we’re not an enterprise supplier either.
Yes. Mercer & Hole is a good example: one London office among four, all supported under a single account and a single point of contact.
