One building in Portsmouth concentrates more of our actual buyers than the rest of the city put together: Lakeside North Harbour, the 120-acre campus that was IBM’s UK headquarters until late 2024. When the council bought it in 2019 for £138m and IBM finished its move to Hursley, what was left was not a tech HQ but a multi-tenant park — 80-plus occupiers, around 97% let, floor after floor of mid-size operators running real operations with no developer in the building. This page is about the software problem that creates, and the related one out in the naval-base supply chain.
The biggest names in Portsmouth are not in the market for what we do. HM Naval Base, BAE Systems Maritime Services, QinetiQ on Portsdown Hill — organisations that size carry their own engineering and resolve software internally. The firms that pick up the phone to an outside team are a tier down: the operators leasing space at Lakeside and the subcontractors feeding the base, both carrying enterprise-grade complexity on tooling meant for something far smaller.
The Business Landscape
HMNB Portsmouth is home to the Royal Navy’s surface fleet, and BAE Systems operates its ship-building and support facilities in the city, including work on the Type 26 frigate programme. The defence sector extends into a supply chain of systems integration, cybersecurity, electronic warfare, and specialist engineering firms. QinetiQ, Lockheed Martin, and a number of mid-sized defence contractors maintain operations in the area. These businesses work within ITAR, Official-Sensitive, and sometimes higher security classifications, and their software must meet corresponding standards.
The aerospace sector has a growing presence, with companies in the wider Solent region working on unmanned systems, satellite technology, and aviation support. The University of Portsmouth has invested in cybersecurity research and data science, contributing both talent and commercial spin-outs to the local technology ecosystem.
Beyond defence, Portsmouth has a maritime heritage sector (the Historic Dockyard is a major visitor attraction), a growing creative and digital sector around the Guildhall area, and a professional services economy serving the city and the wider Hampshire region. The Lakeside Business Park at Western Corridor has attracted technology and services companies looking for modern commercial space.
What Businesses Here Typically Need
Defence contractors need secure operational platforms — systems with multi-level access control, comprehensive audit trails, encrypted data handling, and compliance with government security standards. These are environments where a security misconfiguration is not a bug; it is a contract violation.
Technology companies and professional services firms in Portsmouth need the same kinds of internal platforms and client-facing tools as their counterparts in other cities — but the proximity to the defence sector means there is often an elevated expectation around security practices, even in non-defence work.
Key Commercial Areas
The Naval Base and BAE Systems facilities anchor Portsmouth’s defence economy along the waterfront. Lakeside Business Park at the northern edge of the city is a major commercial hub for technology, professional services, and corporate offices. Fratton and the Guildhall area have attracted creative, digital, and professional services businesses. Port Solent and the waterfront accommodate marine technology and leisure businesses. The University of Portsmouth campus around Guildhall Walk contributes research capability and graduate talent.
What We Offer Here
We work remotely with Portsmouth businesses through structured sprints and transparent communication. Portsmouth’s defence-influenced business culture expects thorough documentation, proper testing, and attention to security — which is how we deliver every project, regardless of sector. Our experience building secure operational platforms, compliance-aware systems, and integration work is directly relevant to the demands of Portsmouth’s economy.
Based in Portsmouth?
Whether you run a five-site operation out of Lakeside or a precision shop bidding into the base, point us at the spot where the manual work happens — the morning copy-paste between systems, the report that takes half a day, the audit pack you assemble from scratch. We will scope the first build around that one thing. Start from the locations overview, or send the detail straight over and we will come back with a plan.
Lakeside North Harbour: one campus, dozens of operators, no engineering floor
A former enterprise-IT headquarters turned multi-tenant campus is an unusually dense pool of the businesses we build for. The occupier list runs from Babcock and LexisNexis to Southern Co-op, Regus and a long tail of logistics, multi-site and professional-services firms — each operationally complex, none of them a software company. Walk the floors and the same gaps recur regardless of sector.
- A core process lives in spreadsheets and a shared inbox, and falls apart the moment it has to run across several sites rather than one.
- Two systems that ought to exchange data instead get reconciled by a person copying figures between them every morning.
- The report a director actually needs takes half a day to assemble from three places, so it gets produced late or not at all.
Nobody on the payroll can build the internal tool that closes those gaps, and a firm at this size cannot justify a full-time engineer who would sit idle between projects. That is the decision Lakeside operators keep arriving at — not whether the system is worth building, but how to get it built without carrying a permanent developer salary. A UK-based team on a retainer answers that better than a single hire: it covers the build, then stays reachable for the next integration or the next site’s rollout. We start by mapping a workflow as it genuinely runs today, then build the internal systems and integrations that let the data move on its own. More often than not the quickest return is an API integration that simply gets two tools the firm already pays for to share what they each hold.
The naval-base supply chain and its certification trail
A few miles south, a different set of firms feeds HM Naval Base, and their pain is narrower but just as costly. Defence subcontracting runs on accreditation: a manufacturer like Portsmouth Aviation in PO3 holds AS9100 and ISO 9001, sits on the JOSCAR register, and carries Cyber Essentials Plus across the whole organisation — all verified. Each of those gates has to be re-evidenced at tender time, and each demands that a delivered part can be traced through its batch, work order and inspection record.
Where this hurts is that the proof tends to sit apart from the work. Quality records, inspection results, works orders and the prime’s accreditation portal occupy separate places, so when an audit or a customer’s documentation request lands, the trail is rebuilt by hand from folders and re-keyed job numbers. We treat this as an integration job before a new-application one: connect the systems that already hold the evidence so a part’s history is assembled on demand, not reconstructed against the clock. (Plymouth’s supply chain carries a similar burden, and our Plymouth page goes deeper on that side of the work.)
