Managed IT, a help desk and cyber security for Square Mile firms, from our office across London Bridge." publisher: Network London legal_name: Verdani Solutions Group Limited updated: 2026-10-09 --- # IT support in the City of London for firms in the Square Mile Network London provides IT support in the City of London for growing businesses of 20 or more people. Our office is in Bermondsey, SE1, across London Bridge from the Square Mile. We look after IT and security for law firms, insurers, finance teams and head offices, with a help desk, cyber security and on-site visits. Ian is the Technical Director at Network London and a certified ethical hacker (CEH), security professional (CISSP) and ISO27001 lead implementer with over 25 years experience. ## What IT support in the City of London covers Firms in the Square Mile work to tight deadlines and strict client rules. We look after IT and security so your people can get on with their work. You deal with one team that knows your setup. - [**IT support and helpdesk**](https://www.networklondon.co.uk/service/it-support): staff reach us by phone, email or portal. Most issues are sorted in one remote session, and support is available 24/7. - [**Cyber security**](https://www.networklondon.co.uk/service/cyber-security): email filtering, device protection and account security, with training that helps staff spot a fake payment request. We hold Cyber Essentials Plus. - [**IT compliance**](https://www.networklondon.co.uk/service/managed-it-compliance): support with Cyber Essentials, ISO 27001 and GDPR, and with the evidence clients and insurers ask for. Their questions are detailed, and we help you answer them with confidence. - [**IT system management**](https://www.networklondon.co.uk/service/managed-it-infrastructure): servers, cloud services and networks, kept up to date so they keep running. - [**VoIP and communications**](https://www.networklondon.co.uk/service/voip): phone systems that follow staff between the office, home and client sites. - [**IT projects**](https://www.networklondon.co.uk/service/managed-it-projects): office moves, fit-outs and system upgrades, planned around your working week. We also help teams use [AI](https://www.networklondon.co.uk/service/ai-development) confidently and safely. For an investment firm, we reviewed an AI platform another company was building for them. We spotted two issues: their data would have been stored in Singapore when it needed to stay in the UK, and they would not have fully owned what they were paying for. They went back to the table knowing what needed to change. ## Does any of this sound **familiar**? - Your IT support is slow to reply, and nobody there knows your setup. - Clients or insurers are asking security questions and you're not sure how to answer them. - The technology you've paid for isn't doing what it should. ## Why use an IT company near the Square Mile Most IT problems are fixed remotely. The ones that are left tend to be urgent, such as a failed network switch or a partner's laptop that will not start on the morning of a big meeting. Those jobs need an engineer in the room. Our office is at LM04.202, The Leather Market, Weston Street, London SE1 3ER. The City is just across London Bridge, so reaching offices near Monument, Bank or Cannon Street does not mean crossing the whole of London. Many City offices sit in large towers with shared risers, building management and strict access rules. A new internet line or extra cabling means working with the landlord and their approved contractors. The older buildings on the City's lanes and courts have their own limits on where cable can go. We can go to those site meetings in person. For founders, partners and directors whose working day can't afford to stop, our VIP concierge service gives a direct line to a senior engineer and IT director who know them, with priority support when they need it. We also take care of the practical things around their working life, such as a new phone or a laptop ready before a trip. ## Who we support in the Square Mile We work with growing businesses of 20 or more people that have a head office or a site in London. In the City that usually means: - Law firms holding confidential client files. See our guide to [IT support for law firms](https://www.networklondon.co.uk/solutions/it-support-for-law-firms-and-solicitors). - Banks, funds and advisers, and the insurance market around Lime Street. Read about [IT support for financial services](https://www.networklondon.co.uk/solutions/it-support-for-financial-services). - Accountancy practices, where year end and tax deadlines leave no room for downtime. See [IT support for accountants](https://www.networklondon.co.uk/solutions/it-support-for-accountants-and-accountancy-firms). - Consultancies and corporate head offices, covered in [IT support for professional services](https://www.networklondon.co.uk/solutions/it-support-for-professional-services). If your office is just north of the City, our page on [IT support in Farringdon](https://www.networklondon.co.uk/solutions/it-support-farringdon) covers Smithfield and Clerkenwell. South of the river, see [IT support in London Bridge](https://www.networklondon.co.uk/solutions/it-support-london-bridge). For the wider picture, read about our [IT support in London](https://www.networklondon.co.uk/). ## Looking for IT support from people who **know you**? - A real person answers the phone, and every ticket gets a human reply. - A familiar team who know your people, your setup and what matters to you. - Help thinking ahead on security, compliance and new systems. ## How to switch IT support provider in the City Many firms put off changing provider because they worry about downtime. Most of the handover happens behind the scenes, and you meet the people first. 1. **Talk to us.** We discuss what is going wrong and what matters to you. Jessica Ruvin, our Operations Director, replies personally the same day. 2. **Get your recommendations.** We start with your business: your people, how you work, the systems you rely on and where the risks are. Then we give you a clear view of what we would recommend. 3. **Hand over and settle in.** You meet the people who will look after you and see a clear handover plan. We take over from your old provider, and faults that keep coming back are fixed at the root. When you are ready, [send us a message](https://www.networklondon.co.uk/contact-us). ## Tell us what you need Jessica, our Operations Director, reads every enquiry and replies personally the same day.
