London buyers rarely ask whether an app can be built. They ask whether it can be explained to a risk committee. For companies in financial services and fintech, the app is only half the deliverable. The other half is the paper trail: where personal data goes, who can read it, how long it is kept and which third parties touch it.
Built to be examined
Financial services is the sector London is best known for, and it shapes what customers and partners ask of a vendor. Security questionnaires, data-processing agreements and due-diligence reviews arrive early. The architecture is documented as it is built, so the answers already exist when the questions come, instead of being reconstructed from memory afterwards. If a customer's questionnaire is already open on your desk, start with the vendor security review.
UK data protection, planned from the start
UK GDPR and the Data Protection Act 2018 set the frame: lawful basis for each kind of data, purpose limitation, retention windows, subject access and deletion. These are database and API decisions before they are policy text. If the product also serves EU users, the same model is planned with EU GDPR in mind so you do not carry two designs. Whether the result meets your obligations is for you and your advisers to judge; the documentation is there for that review.
Contract and invoicing
