Still chasing your IT support company for an answer?
Our clients' most-used words for us are "quick", "efficient" and "as always". You'll know your engineers by name, and you'll never chase a ticket again. Whether you're bolstering an in-house IT team or want fully managed IT support, we're the provider you stop thinking about.
Why Switch to Sheridan?
The reasons clients leave their old provider for us, backed by numbers we can show you.
No Surprise Bills
One predictable monthly fee that covers the lot. No invoice roulette when something breaks, no hourly meter running while it's fixed.
Answered, Not Queued
When something breaks you hear from an engineer, not an autoresponder. It's why the word our post-ticket surveys use more than any other is "quick", with 99% positive feedback across every survey we've ever run.
One Problem. One Call.
You shouldn't have to work out whether a problem belongs to Microsoft, your broadband provider, the firewall or another supplier. Tell us what's wrong and we'll deal with the people involved.
If we're doing our job properly, you'll notice nothing.
Updates fail, backups need checking, security alerts need investigating and servers run out of space. Good managed IT means those things are dealt with before they interrupt your day.
You're not buying a bundle of software licences. You're handing us responsibility for the parts of your IT we manage. When something goes wrong, it becomes our problem to solve.
Organisations Our Engineers Have Supported
We've worked with businesses of every size, both directly and alongside other IT providers.
Certified Partners & Technology Providers
Most IT companies just install security tools. We help build them: our engineers wrote part of OPNsense, firewall software protecting organisations all over the world. See how we help build OPNsense
Real Results for Real Businesses
Real clients, real names, verbatim.
Microsoft 365 Migration
Sheridan's worked on transferring our systems over from our previous provider with Microsoft 365 migration. We
encountered some unforeseen problems during the switch (friday) rather than seeing us
without use on the Tuesday morning, they worked over the bank holiday ensuring we were
ready to go when we reopened.
CCTV Frustration
Contacted from North Wales to help with a UniFi CCTV system and have used
him again several times since for maintenance and upgrades. Sam has helped us out in
an emergency attending over weekend and late one evening.
On-Site Assistance
I have used Sheridan computers for a number of jobs throughout the mainland UK. They have always provided a professional and quality service. I would recommend them to anyone looking for IT and telecoms solutions and would use them again.
Watch Us Work
Every week we publish tutorials and reviews on YouTube covering firewalls, networks and servers. It's the same team that answers your tickets, so you can size us up before you ever pick up the phone.
