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?
We are based in Mayfair and primarily serve Central London, but we support clients across Greater London and beyond. Remote support capabilities mean we can assist your team wherever they are working.
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.
