100% positive customer feedback · 25 years in business
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 100% positive feedback across every survey we've ever run.
Grows When You Do
From five staff to five hundred, get enterprise-grade cloud solutions without enterprise invoices, added as you need them, not sold up front.
Trusted by Leading UK Businesses
Over the years we've worked with many great businesses, directly or indirectly.
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.
