Three services, one accountable team
Most businesses end up with an IT provider, a CCTV company and an electrician — and three people to blame when something stops working. We do all of it.
Managed IT Support
A UK helpdesk that answers, proactive monitoring that catches problems first, and Microsoft 365 managed properly.
- Unlimited helpdesk
- Microsoft 365 & Azure
- Backup & recovery
- Starters and leavers
Cyber Security
Layered protection sized for an SME budget — endpoint, email, identity and the training that stops most breaches.
- Threat protection
- Phishing simulation
- Cyber Essentials support
- Monitoring & response
Security Systems
Cloud CCTV, access control and door entry — designed on the same network, by the same team, with the electrical work included.
- CCTV & access control
- Door entry & intercom
- Network integration
- Maintenance & support
Need Wi-Fi surveys, structured cabling or a multi-site wireless rollout? That's our sister company — SEG WiFi. Same engineers, same group, one order.
Five suppliers’ worth of work, one number to call
A typical office ends up with an IT provider, a CCTV company, a door-entry firm, a cabling contractor and an electrician — and a long conversation about whose fault it is when the front door won't open on a Monday morning.
- One contract, one invoice, one number when something stops working
- Our own engineers on site — the install isn't handed to a subcontractor
- Cabling, containment and power included, not left as “by others”
- Response targets agreed in writing before you sign anything
A clear path from first call to steady state
No lengthy tie-ins before you know what you're getting. The review comes first, and it's free.
Assess
A free IT review of your support, security and licensing. You get a written findings note whether or not you go ahead.
Onboard
We document your estate, take over licensing and support, and fix the obvious risks in the first 30 days.
Secure
Endpoint, email and identity protection deployed, backups proven by test restore, staff trained.
Support
Proactive monitoring, a helpdesk that answers, and a named engineer who knows your site.
Doors, cameras and the buildings they sit in
Installed by our own engineers, with the cabling, containment and power included rather than subcontracted — and maintained by them afterwards.
Landmark Underwriting
A public ground floor and a secure office above it, on one platform.
Softcat plc
Nine offices, nine separate systems, one dashboard by the end of it.
Refeyn Ltd
Three Oxford sites, 50+ cameras, 35 doors — and a platform their US expansion can join.
What we install
Verkada cameras, access control and visitor management — specified, installed and supported by our own engineers.
"SEG Core made setting up our IT simple. They handled everything — Microsoft licences, SharePoint, and Teams — and had us fully up and running in no time. It's been smooth ever since. Never looked back."

Built for the way your business actually works
A warehouse, a care home and a law firm have almost nothing in common technically. We design for the building and the workload in front of us.
Accredited, insured and on the approved lists
SEG Core is a Verkada Gold Partner, and sits inside an accredited electrical contractor.
Through The Specialist Electrical Group, our engineers also carry:
Three brands, one business
SEG Core is one of three trading brands inside The Specialist Electrical Group. Whichever door you come in through, the same engineers, accreditations and back office stand behind it.
SEG Electrical
Electrical installation, EICR compliance, fire detection, renewables and reactive maintenance across the UK.
segplc.com →SEG Core
Managed IT support, cyber security and access control for businesses across the UK and beyond. You’re here.
You are hereSEG WiFi
Enterprise Wi-Fi surveys, installation and structured cabling with guaranteed coverage, across the UK and Europe.
segwifi.co.uk →What that gets you
- A larger pool of directly employed engineers than an IT provider this size would normally have — and a wider range of trades among them
- Electrical accreditations, insurances and method statements already in place for work in live commercial buildings
- One order, one programme and one invoice, whichever brand does the work
- Nobody subcontracted in, and nobody to point at when something stops working

Six reasons clients move to us
One contractor, not four
Most IT providers sub out the cabling, the containment and the power — then nobody owns the join. We do that work ourselves, through the group's own NICEIC-approved electrical engineers.
An engineer answers, not a script
You get a named engineer who has been to your site and knows your kit. No tier-one call centre reading from a flowchart.
Response targets in writing
We agree priority levels and response times with you in writing before anything is signed, so there is nothing to argue about later.
Honest about cost
We set out exactly what drives the price of managed IT, so you can sanity-check any quote you receive — including ours.
Security that includes the door
Access control, door entry and CCTV designed on the same network as your IT, with a leaver losing their door credential the same day they lose their email.
Backed by a real contractor
SEG Core is part of The Specialist Electrical Group — an established electrical contractor with the accreditations, insurance and RAMS to work on live commercial sites.
