Software and system testing for mortgage lenders in London
In short
Forth Systems is an Edinburgh-based software, system testing and AI partner working with mortgage lenders 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 mortgage lenders, affordability rules, fraud and rate-volatility pressure on origination platforms. We work across origination platforms, decisioning engines, valuation providers and broker portals — and deliver higher application-to-completion rates and fewer broker-side errors.
Why mortgage lenders 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 mortgage lenders, affordability rules, fraud and rate-volatility pressure on origination platforms. 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 mortgage lenders
Independent system testing (UAT, SIT, regression, payments and Open Banking conformance), integration work across origination platforms, decisioning engines, valuation providers and broker portals, legacy modernisation, AI integration and platform engineering. Onsite in London when the engagement demands it; remote-first otherwise.
Outcomes mortgage lenders clients see
Engagements typically deliver higher application-to-completion rates and fewer broker-side errors. 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 mortgage lenders 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 mortgage lenders
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.

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 mortgage lenders?
Our delivery to mortgage lenders 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.
