A QUIET SPECIALISM
Two decades of trust.
For over two decades, 123 Technology has been the IT partner of choice for London's most demanding organisations. We combine the personalised attention of a boutique firm with the technical capability of a major enterprise, so you have both without compromise.
Technology underpins everything your business does. We don't wait for things to break. We prevent them, so you can focus on what matters most.
Based in Mayfair, we serve clients across Central London and beyond, building long-term relationships founded on trust, transparency and results.

WHAT WE DO
Six disciplines. One partner.
01. Managed Support
A dedicated team, proactive monitoring, and response times your executive assistant will notice.
02. Cybersecurity
Cyber Essentials Plus aligned. Layered defence designed for organisations that cannot afford a headline.
03. Cloud and Migration
Microsoft 365, Google Workspace, Azure. Transitions handled without drama or lost calendars.
04. Strategic Consulting
Quiet advice on infrastructure, vendor selection, compliance, and what to ignore from your last vendor pitch.
05. Backup and Disaster Recovery
Tested backups, encrypted and off-site. So a ransomware note becomes an inconvenience, not a crisis.
06. Monitoring 24/7
Eyes on your systems through the night and weekend. Most issues are resolved before anyone notices there was one.
WHO WE SERVE
Enterprise-grade IT, delivered with boutique attentiveness.
Professional Services
Dependable IT for consultancies and advisory firms where billable hours start the moment the laptop opens.
Family Offices
Discreet, secure technology for principals and their staff. Confidentiality first, convenience a close second.
Foundations and Trusts
Secure, compliant infrastructure for charitable foundations, so the focus stays on impact rather than IT.
Financial Services
Compliant infrastructure for wealth managers and financial advisers, built for the most exacting regulators.
Creative Agencies
High-performance systems for design, media and collaboration teams, built for deadlines that will not wait.
Real Estate
Resilient IT for investors and asset managers, built for confidential transactions and teams that rarely sit still.

FREQUENTLY ASKED
Common questions, answered plainly.
What is a managed service provider?
An MSP remotely manages your IT infrastructure and systems on a proactive basis. Rather than waiting for things to break, an MSP like 123 Technology monitors, maintains and supports your technology around the clock for a predictable monthly fee.
How much does managed IT support cost?
Costs vary depending on the size of your organisation, the complexity of your infrastructure, and the level of support required. We offer bespoke pricing tailored to your specific needs. Contact us for an assessment and no-obligation proposal.
How quickly do you respond to IT issues?
Our average response time for critical issues is under 15 minutes. All clients benefit from our 24/7/365 monitoring, and our helpdesk is staffed during business hours with emergency support always available.
Do you only support businesses in Central London?
No. Most of our clients are a short walk from our Mayfair office. A good number are not. Wherever your team works, on-site or remote, our support travels with them.
What industries do you specialise in?
We have deep expertise across financial services, family offices, creative agencies, professional services, foundations and trusts, and real estate — sectors where security, compliance and reliability are non-negotiable.
How is 123 Technology different from other IT firms?
We combine the personalised attention of a boutique firm with enterprise-grade technical capability. With over 20 years serving London businesses, we focus on prevention over cure, resolving issues before they impact your operations.
