What do app development companies in London charge?

London agencies quote £100–180/hr for senior mobile and web work. Codazz delivers React Native, Next.js and open-banking integrations at fixed project fees — typically 40–55% below local rates — with delivery from Edmonton and Chandigarh and GMT overlap.

Can you build FCA-compliant fintech apps in London?

Yes — open banking APIs, neobank features and payment flows with PSD2 and FCA documentation are core London engagements. We produce the control evidence UK regulators and sponsor banks request.

Does Codazz have an office in London?

No physical London office — we serve UK clients remotely from Edmonton (HQ) and Chandigarh, with daily standups on GMT/BST and in-person visits when needed. 80+ UK projects delivered.

Do you build NHS-integrated healthtech for London providers?

Yes — patient portals, appointment systems and FHIR integrations aligned to NHS Digital standards are standard UK healthtech builds with GDPR and UK GDPR compliance baked in.

How do you handle GDPR for London software projects?

GDPR is scoped in discovery: data minimization, consent flows, DPIAs and UK/EU data residency on AWS eu-west-2 or Azure UK South. We produce privacy documentation procurement teams expect.

Do you offer post-launch support for London clients?

Yes. Every London project includes a 30-day warranty. Ongoing SLAs cover monitoring, security patches and feature sprints — with a dedicated engineer reachable during UK business hours.
