Software and system testing for building societies in London
In short
Forth Systems is an Edinburgh-based software, system testing and AI partner working with building societies in London and across England. London is the centre of UK banking, payments, insurance and capital markets — every meaningful regulated firm has people, controls and obligations here. For building societies, modernising legacy platforms without breaking the trust the brand depends on. We work across mortgage origination platforms, savings cores, member portals and treasury tooling — and deliver lower run cost, faster product change and a recruitable engineering stack.
Why building societies in London work with Forth
London is the centre of UK banking, payments, insurance and capital markets — every meaningful regulated firm has people, controls and obligations here. For building societies, modernising legacy platforms without breaking the trust the brand depends on. We're a small, senior, UK-staffed team — engagements are run by named engineers with regulated-environment fluency, not an offshore pool.
What we deliver for building societies
Independent system testing (UAT, SIT, regression, payments and Open Banking conformance), integration work across mortgage origination platforms, savings cores, member portals and treasury tooling, legacy modernisation, AI integration and platform engineering. Onsite in London when the engagement demands it; remote-first otherwise.
Outcomes building societies clients see
Engagements typically deliver lower run cost, faster product change and a recruitable engineering stack. Every output is version-controlled, evidence-ready and mapped to the FCA, PRA, DORA, ISO 27001 or sector-specific controls that apply.
How a London engagement runs
Step 1: a fixed-scope, paid discovery against a real building societies workload. Step 2: a 30-day pilot that ships measurable change. Step 3: a continuation engagement with named engineers, monthly reporting and a clear renewal point. No long contracts before evidence.
Why a UK-onshore partner matters for building societies
Second-line and regulators increasingly want clarity on who staffs critical work, where data sits and how vendor risk is controlled. We're UK-incorporated, UK-staffed and set up for DPAs, supplier security questionnaires, third-party risk assessments and Crown Commercial DPS engagement.
Frequently asked questions
Do you work with building societies based in London?
Yes — most of our work is delivered into FCA-regulated and infrastructure firms, including building societies based in London and elsewhere in England. Anonymised case studies are available on request.
Can you be onsite in London?
Yes. Forth Systems is Edinburgh-headquartered with named engineers onsite in London where the engagement requires it. Remote-first otherwise, with the same governance either way.
What regulatory frameworks do you cover for building societies?
Our delivery to building societies maps to FCA, PRA, DORA, Consumer Duty, SS2/21 and ISO 27001 evidence requirements where they apply, with traceable test scenarios and audit-ready evidence packs.
How fast can you start an engagement in London?
Most engagements start within 2-4 weeks of a signed SoW, with onsite presence in London arranged within the same window when required. Faster where an existing supplier framework is in place.
