Managed IT Support for Professional Services Firms in London & the Home Counties
Better support, measured and guaranteed. Switching is our problem, not yours.

Read a text transcript of this video
For growing businesses, managing IT becomes a job in itself. You've got a team to support, people joining and leaving, and a business that needs to stay secure. That's what we take care of at Little Big Tech — IT and security support for professional services firms in London, typically ranging from 5 to 50 people in staff. We look after your team day to day, including joiners and leavers. We manage and secure your technology. We give you a clear stance of where you stand with our Technology Resilience Score, and we give you a roadmap on what to improve next. And that matters more than it used to — cyber attacks are becoming more targeted than they did just a few years ago, and insurers are expecting more from your security. I work for the businesses that come to Little Big Tech for exactly that reason. Now, most IT providers will tell you that they're responsive. 99% of support tickets get fixed the same working day, and 100% within the SLA agreed. And that's not just our marketing figures — our security and service performance is independently verified every six hours, against the framework that UK regulators use for critical national infrastructure. We're the first managed service provider to do that. That verification sits behind your Technology Resilience Score — your technology today, and where it's heading. The pricing is on the website: £75 per user per month, 10-user minimum, one rate, no hidden fees. And if you already have an IT provider, we handle the switch — we speak to your current provider, manage the handover, and, most importantly, keep your team working through it. If that sounds like something you've been looking for, we'll look at where your technology stands, where the gaps are, and whether Little Big Tech is the right fit for your business. Book 15 minutes with us.
We'll compare what you've got to what you could have.

How we do it
We measure it
Your Technology Resilience Score™. Our resilience benchmark is 3.5 out of 5. Your assessment identifies the gaps to address first.
Your Resilience Score shows what your current provider hasn't been doing.
We're accountable for it
In May 2026 we became the first MSP to carry the Assurix Trustmark. Most of the figures below are independently re-verified by Assurix every six hours; our same-day resolution figure comes from our own internal support records — see the source under each card.
Cyber Essentials support included.
We guarantee it
We'll make your business more resilient in 90 days. If we don't, we stop charging. See the 90-Day Resilience Guarantee →

Figures as of 2026-09-09. Verified figures are re-checked by Assurix every six hours, not once a year. Support figures are pulled from our internal support records — spam, duplicates and abandoned tickets excluded, and “same working day” means within our support hours excluding time waiting on the client. “Resolved within our agreed SLA” means within the response and resolution targets set out in each client's service agreement. “Critical vulnerabilities” means those rated Critical or High severity in the relevant vendor's security advisory.
