Managed IT Support That Keeps London Businesses Running

What Managed IT Support Actually Means

Managed IT support is a fixed monthly service where an external team takes ownership of your technology — monitoring it, securing it, maintaining it, and supporting your people — so your business runs without interruption.

In 2026, the average London business relies on dozens of SaaS tools, a hybrid workforce, and infrastructure that spans on-premise servers, cloud platforms, and employee home offices. The complexity has outpaced what most internal teams can handle alone.

Outsourced IT support is no longer a cost-cutting exercise. It is the difference between a business that reacts to problems and one that prevents them.

Proactive vs Break-Fix: The Core Difference

The model you choose shapes everything else.

• Break-fix is reactive. You call someone when a server dies or a laptop won’t boot, and you pay by the hour. The provider only earns when something has already gone wrong — so there is no incentive to prevent the next outage.
• Managed IT is proactive. We watch your systems continuously, patch and harden them before issues surface, and charge a predictable monthly fee. Our interests are aligned with yours: fewer incidents, less downtime, a calmer week.

That shift from reactive to proactive is the point. With continuous monitoring in place, the quiet problems — a failing disk, an expired certificate, a switch running hot — are often caught and resolved before they become loud outages.

What’s Included in Managed IT Support

When you partner with Nerdster, you get a team that treats your infrastructure like their own. A typical plan covers:

• 24/7 helpdesk — a single number and email reach a real engineer. No phone trees, no three-day ticket queues.
• Proactive monitoring and patching — lightweight agents on every endpoint, server and network device, reporting to our operations centre around the clock.
• Endpoint security — managed antivirus, encryption and device hardening across your fleet.
• Cloud and Microsoft 365 management — licensing, identity, mailboxes, SharePoint and Teams kept tidy and secure.
• Backup and disaster recovery — tested backups and a recovery plan, so an outage or ransomware hit is a hiccup, not a crisis.
• Onsite response across London — an engineer to your office when hands-on work is needed.
• Strategic and vCIO guidance — quarterly reviews where we plan budgets, lifecycle replacements and roadmap, not just close tickets.

Built for London’s Regulated and Professional Firms

We cut our teeth supporting hedge funds and private equity firms, where downtime during market hours is not an option. That background shapes how we work — and it suits the firms we serve best:

• Financial services — funds, wealth managers and family offices that need resilience and audit trails.
• Professional firms — law, accountancy and consultancy practices handling sensitive client data.
• Ambitious SMEs — fast-growing businesses that have outgrown ad-hoc support and want IT that scales with them.

What these firms share is a low tolerance for downtime and a high bar for data handling. Many also have a single internal IT contact who fields day-to-day questions while we manage infrastructure, security and escalations behind them — a model that works well and keeps in-house knowledge in the business.

Compliance is where we genuinely differ. Every process is documented and every change is logged. When your auditors, your insurer, or the FCA ask questions, we have answers ready. We can align your environment with Cyber Essentials certification and support your obligations under DORA and broader operational resilience — strengthened by dedicated cybersecurity services.

Response Times and SLAs

When something does go wrong, what matters is a calm, predictable response.

Your team reaches our helpdesk directly, and a real engineer triages the issue rather than logging it for later. In practice our first response sits at around 8 minutes against a target of under 15, and common issues are typically resolved within half an hour.

Every client has a written SLA that sets priority levels and resolution targets by issue type, so expectations are clear and measurable — and reported back to you monthly. A laptop that won’t boot before an important meeting is treated differently from a low-priority software request, and the SLA spells out exactly how each is handled.

Response time is a floor, not a ceiling. Because we monitor proactively, we often open a ticket and begin work before your team even notices there is a problem.

How Per-User Pricing Works

Our managed IT support plans start at £45 per user per month. The model is deliberately simple:

• You pay a flat fee per person, not per incident or per hour.
• The agreed scope — helpdesk, monitoring, patching, security, vendor liaison and reviews — is fully included.
• Hardware procurement and discrete project work are quoted separately and approved in advance, so there are no surprises on an invoice.

Because the price scales cleanly with headcount, budgeting stays straightforward as you grow. For a fuller breakdown, read our guide on how much IT support costs in London.

Onboarding and Transition

Switching provider should not mean a week of disruption. Most businesses are fully onboarded within 10-15 working days:

1. Discovery — we audit your environment, users, devices and licences.
2. Documentation — everything is mapped so knowledge does not live in one person’s head.
3. Deployment — monitoring, security and backup tooling go live across your fleet.
4. Handover — we coordinate with any outgoing provider and brief your team on how to reach us, with no gap in cover.

How We Work

Contracts run on 30-day rolling terms after an initial 90-day onboarding period. We would rather earn your continued trust through the quality of our work than rely on a long lock-in. You get a named account manager, engineers who take the time to learn your systems, and the discipline of a team grounded in regulated finance — applied with the same care whether you run a 10-person consultancy or a 200-seat trading floor.

Discretion and reliability sit at the centre of how we operate, which is why the firms we look after tend to stay with us for the long term. Explore our wider IT support in London offering to see how the pieces fit together.
