Service Scope

Everything your
business needs.

Our London IT support contracts are comprehensive. You get far more than a helpdesk — a complete IT department for a flat monthly fee, with no surprise invoices.

01

24/7 Helpdesk & Remote Support

Unlimited helpdesk via phone, email, or portal. Remote resolution for most issues within 30 minutes. No call limits, no per-ticket charges — all included in your monthly fee.

02

Proactive Infrastructure Monitoring

All servers, endpoints, and network devices monitored continuously, 24 hours a day. We detect and resolve issues before they cause downtime — often before you're aware of them.

03

Cyber Security Built In

Endpoint protection, email security, multi-factor authentication, and monthly vulnerability scanning included as standard. No paying extra for basic security on top of your IT contract.

04

Cloud & Microsoft 365 Management

Full Microsoft 365 administration, Azure management, cloud licensing, and migration support. We keep your cloud environment secure, licensed correctly, and optimised.

05

Backup & Disaster Recovery

Automated daily backups with off-site replication, tested recovery procedures, and a documented business continuity plan. We ensure you can recover fast from any incident.

06

Dedicated Account Manager

A named account manager who understands your business, handles escalations, and runs quarterly reviews to keep your IT strategy aligned with your goals.

Why London Businesses Choose CITS

Local expertise.
Enterprise capability.

Based in New Malden, we support businesses across Greater London and Surrey. We understand the pace, standards, and expectations of London businesses — and we deliver accordingly.

Fast On-Site Response
Our engineers are based locally. For critical on-site issues we aim to be with you within 2 hours anywhere in Greater London — remote resolution typically within 30 minutes.
Proactive, Not Reactive
We monitor and resolve issues before they reach you. Over 80% of incidents we handle are detected by our monitoring systems before a user reports anything.
Security-First Approach
Every managed IT client gets baseline cyber security built in — not as an add-on. Endpoint protection, email security, MFA, and monthly vulnerability scanning included.
Flat Monthly Pricing
Fixed monthly fees with no surprise invoices for common requests. You always know exactly what your IT costs — and our incentive is to prevent problems, not profit from them.

Compliance & Security Built In

IT support that also
keeps you compliant.

Our managed IT service includes the security controls and audit evidence that ISO 27001, Cyber Essentials, and GDPR require. No paying extra for compliance add-ons — it's part of how we work.

Client Testimonials

Trusted by London
businesses.

Don't take our word for it — here's what clients across London and Surrey say about working with CITS.

★★★★★

"CITS transformed our IT completely. Within the first month they resolved issues that had been plaguing us for two years. Response times are incredible — usually fixed before I've even sent a second email."

James Richardson
Director, Richardson Legal LLP — London
★★★★★

"Finally an IT company that speaks plain English. They assessed our setup, told us honestly what needed fixing, and did it without any pressure. Best IT decision we've made in five years."

Sarah Mitchell
Operations Manager, Nexum Healthcare — Surrey
★★★★★

"Our previous IT company was reactive — they'd fix things after they broke. CITS is completely different. We've had zero unplanned downtime in 18 months. Worth every penny."
