Managed IT support in Portsmouth: what is included and how the contract works
Managed IT support is a monthly service that keeps a Portsmouth business running rather than charging per breakage: proactive monitoring and patching, Microsoft 365 administration, security baselines, backup, and a helpdesk with named engineers. Portsmouth is twenty minutes along the M27 from our Southampton base, so on-site visits for hardware, network or office moves are practical rather than theoretical.
Before signing any IT support contract in Portsmouth, get the scope in writing — which devices, users, applications and sites are covered, what is included in the monthly fee and what is chargeable — and ask for the response times and the notice period in the same document. We set these out before you sign and report against them every month.
| Service area | What it covers | Suits |
|---|---|---|
| Helpdesk and user support | Remote and on-site support for Windows and macOS users, with named engineers and agreed response times. | Every business; the core of the service. |
| Microsoft 365 and Google Workspace | Licensing, migration, MFA, conditional access, email protection and backup. | Offices, professional services, hybrid teams. |
| Security and Cyber Essentials | Endpoint protection, patching, device encryption, documented baselines and certification evidence. | Defence supply chain, professional services, anyone asked by insurers or clients. |
| Devices and lifecycle | Procurement, imaging, onboarding and leaver processes, asset register. | Growing teams and multi-site businesses. |
| Network and connectivity | Firewalls, Wi-Fi, leased lines and broadband managed alongside IT so nobody blames anyone else. | Offices moving or upgrading connectivity. |
Leased lines Portsmouth
Leased lines and business broadband in Portsmouth
Portsmouth commercial addresses across PO1–PO6 — the city centre, Lakeside North Harbour, Gunwharf, Cosham and the North End industrial areas — generally have good full-fibre availability from more than one carrier, which keeps leased-line pricing competitive. A leased line suits Portsmouth businesses whose connection carries voice for a busy office, hosted applications or links to other sites; FTTP with 4G/5G failover suits most others.
| Option | What it is | Suits which Portsmouth businesses | Typical considerations |
|---|---|---|---|
| Business FTTP | Full-fibre broadband to the premises, up to around 900 Mbps down. Shared (asymmetric) service. | Most offices, practices, shops and hospitality venues. | Availability varies by street; install usually within weeks; pair with 4G/5G failover for continuity. |
| SoGEA | Broadband over the copper line without a phone service. Replaces FTTC ahead of the PSTN switch-off. | Addresses without FTTP yet; smaller offices with modest needs. | Speeds depend on distance to the cabinet; interim option until fibre arrives. |
| Ethernet leased line | Dedicated, symmetrical fibre with a service level agreement and repair target. | Cloud-heavy offices, dialling floors, sites that cannot lose connectivity. | 60–90 working day lead time; excess construction charges possible; sized to concurrent users and voice. |
| 4G/5G business broadband and failover | Mobile-network connectivity via a business router with external antenna. | Backup for any of the above; primary for temporary or hard-to-reach sites. | Automatic failover in seconds; data allowance sized to how long you need to run on it. |
- Leased-line quotes returned across every deliverable carrier, with lead times and any construction charges stated up front.
- Multi-site designs linking Portsmouth with Southampton, Fareham, Gosport and Havant under one network and one phone platform.
- 4G/5G failover as standard on business-critical sites.
- Managed alongside your IT and phones so a connectivity fault has one owner.

“Good guys — worked with them to switch over from a previous very good supplier. They have gone above and beyond to understand our needs and bespoke systems to help support our specific needs. Transition over on getting their systems up and running was smooth. As a small business owner, trust and confidence are important to me.”

“We have been using Josh at Atom for a few years now. Service has always been amazing. Just today our router blew up due to a power surge and he came out promptly with a new one to make sure we were back online in time for trading. Would highly recommend.”

“There aren’t many telecom providers that can be described as truly honest and straightforward. Georgia was very well spoken and made me feel my company was in the right hands. Ollie and Josh responded promptly throughout getting my phones and security systems set up. The install was seamless with no drop in connectivity and no technical issues since.”
