IT Support in the City of London, Built for Regulated Firms
Trading desks, compliance deadlines and landlord-controlled buildings. We support the firms that cannot afford an outage between 07:00 and 18:00.
The City Has a Specific IT Problem
Square Mile firms are small headcount, high consequence. A 40-person asset manager in EC2 runs infrastructure complexity closer to a 400-person business: market data feeds, regulated record-keeping, multiple counterparty portals, and a client base that notices immediately when email stops.
That combination breaks the usual mid-market IT model. Generalist support is fine until the FCA asks how you would keep an important business service running through a supplier failure, or until a trading application stops talking to a data feed at 07:30.
What We Actually Do Differently Here
We schedule around the market, not around our convenience. Every change has a window. Nothing that could interrupt a desk happens while the desk is live.
We keep the evidence current. FCA operational resilience and DORA both expect documentation that reflects reality — asset inventories, ICT third-party registers, incident timelines. Producing that during normal service is far cheaper than reconstructing it under review.
We plan for the building, not just the network. City offices come with riser restrictions, landlord-appointed cabling contractors, permitted working hours and lead times measured in weeks. Ignoring that is how office moves slip.
Who We Support in EC1–EC4
Our City clients cluster around regulated financial services — hedge funds, private equity and wealth managers — alongside the law firms and professional services businesses that serve them.
The common thread is not sector. It is that downtime has a direct, immediate cost, and that a regulator will eventually ask how the technology is governed.
Getting There
We are based at 71-75 Shelton Street in Covent Garden. That is roughly 15 minutes to Bank, 20 to Liverpool Street, and walkable when the Tube stops — which matters more often than anyone plans for.
Alongside the City we support firms across Mayfair and the West End and north London, and provide managed IT support across Greater London.

We Work Around Market Hours
Nothing disruptive happens between 07:00 and 18:00. Patching, migrations and switch replacements run in agreed evening or weekend windows, because a City trading floor cannot absorb an unplanned reboot.
Regulator-Ready by Default
Asset registers, incident logs and third-party risk documentation are produced as part of normal service, not scrambled together the week before an FCA or DORA review.
We Speak Building Management
Most City comms rooms are landlord-controlled with their own access procedures and riser rules. We handle the permits, escorts and lead times so your move or upgrade does not stall.
FAQ
Frequently asked questions
How quickly can you get an engineer to an EC2 or EC3 office?
For contracted clients in the City we target on-site attendance within 60 minutes during business hours. Our team is based in Covent Garden, which is 15-20 minutes away by Tube or on foot in a disruption. Most issues are resolved remotely first, so an on-site visit is usually about hardware rather than diagnosis.
Do you support Bloomberg, Refinitiv and other market data terminals?
Yes. We handle the desktop side — connectivity, entitlements, peripherals, multi-monitor setups and the interaction between terminal software and your security tooling. Terminal licensing and market data contracts stay with the vendor, but we coordinate with them on your behalf.
Can you help us evidence FCA operational resilience requirements?
Yes. We map your important business services to the underlying IT, document impact tolerances, and maintain the incident and third-party registers your compliance team needs. See our FCA operational resilience page for the detail.
Our comms room is controlled by the building, not us. Is that a problem?
It is normal in the City and we deal with it routinely. We manage the access requests, insurance and method statements that landlords require, and we schedule work around the building's own permitted hours.
Do you work with firms that already have an in-house IT person?
Frequently. Co-managed IT is common in the City — your internal person handles the business-facing work while we provide 24/7 monitoring, security operations, escalation and holiday cover. It usually works out cheaper than hiring a second internal hire.
