IT Support for London

We offer IT consultancy in London, supporting businesses like yours as you work to drive growth, improve stability, and reduce operational risk.

Reduce risk and drive growth with our managed IT support

Most internal IT teams find it impossible to provide consistent, predictable, high-quality service to the wider business. That’s not their fault, because they’re often under-resourced and don’t have the enterprise-grade tools needed to deliver efficiently. This affects productivity, slows down projects, and creates the kind of hidden operational cost that CFOs, CTOs, and IT Directors feel every day.

Our job is to augment your internal IT team. We take responsibility for every device you deploy from initial purchase through to replacement, making sure it’s maintained and secured throughout its lifecycle. We handle end-user support so your internal IT can focus on strategic work that drives value rather than being pulled into constant firefighting.

Here’s what happens. We remove the friction that’s eating up your team’s time and your budget. You get fewer interruptions, fewer avoidable problems, and a more predictable managed IT service that supports long-term growth and stability.

System Care

We provide support to your on-premises infrastructure.

If you need help with your on-premises systems, you need System Care rather than general managed IT support. We take care of your IT estate, updating PCs and servers to maintain security and maximising the service life of your IT assets. This gives IT Directors a more stable environment, supports CTO planning, and offers CFOs clearer asset value over time.

Cloud Care

We provision, configure, support, and manage a range of cloud services.

Need help migrating to the cloud? Or need a hand overseeing your cloud subscriptions? Our Cloud Care service monitors and optimises your cloud software to minimise spend and improve efficiency. This supports London organisations that want more predictable cloud costs, stronger managed IT hosting, and better visibility across their cloud estate.

Cyber Care

We monitor, respond, and manage threats to keep our customers safe.

Looking to improve your cyber health posture? Our Cyber Care service constantly checks your systems for suspicious activity and helps you reduce risk. We monitor, respond, and manage threats on your behalf, which strengthens your organisation’s resilience, supports your cyber strategy, and forms an important part of your wider IT disaster recovery service planning.

We’ve supported International House London’s Finance Team with Business Central

The main challenge was that IH London’s existing finance system was cumbersome, built on older technology, and couldn’t provide the efficient processes or the level of complexity needed to support the finance department and wider business.

IH London’s finance team spent time with TSG discussing the problems with its on-premises server and the need to work remotely, streamline processes, and increase efficiency. Together, IH London and TSG chose Microsoft Business Central for its cloud capabilities, automation, integration features, reconciliations capability, and its strong Microsoft foundation.

Carl has the requisite combination of business experience and technical expertise that enabled him to understand clearly what we needed and how to best provide that… It has been a pleasure of working with Carl and his team to get Transform Housing into the world of business intelligence and we look forward to further collaboration.

David and James, Transform Housing

We have used TSG as our managed service provider for nearly three years providing us with support for our devices, provision of an Azure server for our data management tool and helping us in our journey to Cyber Essentials accreditation. We are always ready to recommend them to our own customers, their service is good and the account management service has been brilliant.

Claire Bayliss, Director

BioPhorum set out to radically improve our member experience as well as reduce our operational overhead. Our catch phrases were "delight customers" and "manage at scale". TSG supported BioPhorum on a multi-year journey to deliver a Microsoft platform solution which has met its first round of objectives and continues to provide a flexible platform for ongoing change within the business.

David Reinhardt, Head of IT & Platform One Project Manager

Overall, the transition to the Cloud was seamless and, for the majority of colleagues, almost imperceptible - which is always a good measure for any IT project. We really appreciate the ease and simplicity of logging on to and using the Azure Virtual Desktop. Working remotely has never been easier.
