Service Overview

Product Design Solutions for London Businesses

London is the world capital of consumer financial product design, and the bar is set by teams whose work has reshaped global UX expectations. Monzo's design organisation pioneered transparency-first banking UX, plain English copywriting, and accessibility-first onboarding that competitors from Singapore to San Francisco now imitate. Revolut, Wise, Starling, Tide, Citymapper, Deliveroo, and Bumble (founded in London) sit alongside agency benchmarks set by Pentagram London, ustwo (creators of Monument Valley and a design studio with a serious product practice), Method (now part of Reply), AnalogFolk, Made by Many, ELSE, Fold7, Friends From SE1, and Studio Output. Codazz designs and ships production digital products for London founders, fintechs, healthtech, retail, and public sector teams operating inside this ecosystem. We build design systems and product experiences that meet UK GDPR consent obligations, the Equality Act 2010 and Public Sector Bodies Accessibility Regulations (PSBAR) 2018, WCAG 2.2 AA, the FCA Consumer Duty effective July 2023 with its outcomes-based test for product communications, and the Online Safety Act 2023 where user-generated content is in scope. Our engagements run on GMT and BST hours with our Edmonton and Chandigarh hubs, and deliver a documented design system, accessibility conformance pack, and Plain English content review suitable for ICO scrutiny, FCA file reviews, or a Government Digital Service assessment.

What We Build

Product Design Services We Offer in London

London product design clients expect a standard set by Monzo, Revolut, Wise, Starling, Citymapper, Deliveroo, and the agency tier including Pentagram London, ustwo, Method, AnalogFolk, Made by Many, and ELSE. Our product design services mirror that bar. We deliver financial-grade transparency UX (clear fee disclosure, no asterisk traps, plain English first), conversational interface patterns borrowed from the Monzo and Tide playbooks, GDPR-first consent design without dark patterns (granular per-purpose consent, equal weight reject and accept buttons, no pre-ticked boxes), WCAG 2.2 AA conformant component libraries authored in Figma with full Storybook handoff, and content design grounded in the Plain English Campaign and GDS style guide. Every engagement includes an accessibility audit, a Consumer Duty fair value review for regulated financial products, and a content lint pass for reading age and ambiguity.

Industry Expertise

Product Design for London's Key Industries

London product design demand concentrates in financial services, where we have the deepest delivery experience. Monzo, Revolut, Wise, Starling, Tide, OakNorth, and Atom Bank sit alongside legacy incumbents (Lloyds, Barclays, HSBC, NatWest) modernising digital experiences. Our financial designs meet FCA Consumer Duty obligations on consumer understanding and fair value, design out dark patterns the ICO has called out, and produce the audit documentation a Section 166 skilled persons review would expect. In healthtech, NHS Digital, Babylon Health (legacy), Doctorlink, and Livi require alignment with the NHS Digital Service Manual and DCB0129 clinical safety standards. For public sector, we design to the Government Digital Service service standard, GOV.UK Design System patterns, and PSBAR 2018 accessibility. We also serve London retail and marketplace clients (ASOS, Farfetch, JustEat) and creative platforms (DeepMind public-facing, ARM developer tooling, Improbable), where the design ceiling is set by Pentagram and ustwo and clients expect equivalent craft.

Our Process

Our Product Design Development Process

We run discovery, design, and handoff on London hours so product, legal, compliance, and risk leads attend synchronous workshops rather than chasing overnight Figma threads. Discovery opens with a Consumer Duty outcomes workshop for regulated financial clients (mapping product, price, consumer understanding, and consumer support outcomes), a UK GDPR and ICO dark patterns review for any consent or marketing flow, and a WCAG 2.2 AA gap audit if an existing product is in scope. Design phase produces a Figma component library, content templates written to Plain English Campaign standards, and motion specs reviewed against vestibular safety guidance. We test with real users recruited through People for Research or Respondent, including users with disabilities and users on low-bandwidth connections, then ship a launch-ready design system. Public sector projects follow GDS service standard assessment cycles, which we plan into the timeline.

Technologies We Use for Product Design

London product design tooling defaults to Figma with full design token architecture, Tokens Studio for cross-platform token export, and Storybook for engineering handoff with axe-core integrated into the CI pipeline. We use Lokalise for English UK, English US, and European locale management where the product expands beyond the UK. Accessibility tooling includes axe DevTools, Stark, Tota11y, manual NVDA and VoiceOver testing, and BrowserStack for cross-device assistive technology coverage. Content design uses Hemingway Editor and Acrolinx for reading age and tone consistency. For motion we author in Lottie and Framer Motion with prefers-reduced-motion respected at the token layer, which is what the Monzo and Revolut design systems do. PSBAR conformance documentation is generated from the test suite, not written retrospectively.

Why Choose Us

Why London Businesses Choose Codazz for Product Design

We combine world-class engineering with local market understanding to deliver product design solutions that drive real business outcomes.

🏦

Monzo-Grade Financial Design

We design financial products to the standard set by Monzo, Revolut, Wise, and Starling: plain English transactional copy, transparent fee disclosure, conversational support UX, and FCA Consumer Duty fair value documentation. That is the global ceiling for consumer fintech UX, and London is where it was set.

🔒

GDPR-First Consent Design

Every consent and marketing flow is designed against ICO dark patterns guidance: granular per-purpose consent, equal weight accept and reject, no pre-ticked boxes, plain English purpose explanations, and a clear withdraw flow. We design in compliance, not retrofit it after the ICO publishes an enforcement notice.

WCAG 2.2 AA & PSBAR Conformance

Every engagement ships with a WCAG 2.2 AA conformance pack including the nine new 2.2 criteria, NVDA and VoiceOver test reports, and a PSBAR-aligned accessibility statement. Public sector work meets the GOV.UK Design System and GDS service standard, not a vendor-specific approximation.

🎓

RCA & Royal Academy Talent Density

London hosts the Royal College of Art (#1 globally for design), Central Saint Martins, and Brunel Design, feeding Pentagram, ustwo, Monzo, and Apple. We recruit against that benchmark and collaborate with RCA-network specialists when projects require craft beyond a single agency's in-house capability.

📍

Frequently Asked Questions About Product Design in London

Ask a Question

Design in London is quoted by surface area, and the surfaces vary enormously: a scoped product design sprint for a London MVP, a full design system build with WCAG 2.2 AA conformant component library, content design, motion specs, and Storybook handoff, or end-to-end product design for a regulated FCA-authorised fintech including Consumer Duty fair value documentation, ICO-reviewed consent flows, and PSBAR conformance. Scope drivers include research depth, a design system foundation, and a clickable Figma prototype. London rates sit above Manchester, Bristol, and Edinburgh because of the Monzo and Revolut talent premium and Royal College of Art density. We quote fixed-fee, not open T and M, with a clear scope of work.

The FCA Consumer Duty, effective 31 July 2023 for new and existing products and 31 July 2024 for closed products, places obligations on financial firms to deliver good outcomes for retail customers across four pillars: products and services, price and value, consumer understanding, and consumer support. The design implications are concrete. Disclosure must be in plain English at a reading age the target customer can actually understand (the FCA tests this). Comparison and pricing must support informed decisions, not obscure them. Onboarding and product journeys must not exploit behavioural biases (sludge, friction, dark patterns). Vulnerable customers must be supported without being singled out. Our financial engagements produce a Consumer Duty design audit, a fair value assessment for product UX, and Plain English content templates testable against the FCA's own readability expectations.

The Information Commissioner's Office (ICO) has published explicit guidance on consent design and dark patterns, and enforcement has stepped up since 2022. Our GDPR-first consent design covers granular per-purpose consent (not bundled), equal visual weight on accept and reject buttons (the ICO has called out unequal styling specifically), no pre-ticked boxes, no nudge language that biases the decision, plain English purpose explanations, and a clear withdraw consent flow accessible from account settings, not buried six levels deep. We design data subject access request flows that meet the one-month statutory response window, and we coordinate with client DPO and legal during the design phase, not after a complaint surfaces. Cookie banners follow the ICO's published patterns, including separate consent for analytics and marketing.

Yes. Every London engagement ships with a WCAG 2.2 AA conformance pack including an axe-core automated test suite, manual NVDA and VoiceOver test reports, keyboard navigation audit, and a published accessibility statement aligned with the Government Digital Service template. For public sector clients subject to the Public Sector Bodies (Websites and Mobile Applications) (No. 2) Accessibility Regulations 2018, we produce the procurement-ready accessibility statement, a documented test methodology, and a remediation plan for any non-conformances disclosed. WCAG 2.2 added nine new success criteria over 2.1 (focus appearance, dragging movements, target size, consistent help, redundant entry, accessible authentication) and we test against all of them, not the 2.1 subset many vendors still use.

Yes. The Royal College of Art ranks first globally for art and design in the QS World University Rankings by Subject and has produced design directors at ustwo, Pentagram, Monzo, and Apple. Central Saint Martins (UAL) and Brunel Design feed similar pipelines. We recruit against that talent benchmark and stay current with London design venues including the RCA degree show, Pentagram's published case studies, and the UX London and Design Indaba conferences. For projects requiring specialist craft (brand identity, illustration, motion direction) we collaborate with RCA-network freelancers rather than overclaiming in-house capability. We are transparent about which work is delivered in-house and which is partnered, and we have introduced London clients to RCA InnovationRCA when the engagement scope warrants it.

Public sector products subject to a Government Digital Service service standard assessment must use the GOV.UK Design System or justify deviation. Our public sector engagements build on the GOV.UK component library, follow the GDS service manual through alpha, beta, and live phase definitions, and produce the artefacts a service standard assessment requires (user research findings, accessibility statement, performance metrics, GOV.UK style guide content). We work to the GDS principle that the service must be the same for every user, not a separate accessible version, and we test with users on assistive technology, low-bandwidth connections, and older devices. For local authority or NHS work we align with the NHS Digital Service Manual where applicable, which extends GDS patterns with clinical safety considerations.

Yes. The Monzo conversational UX pattern (chat-style support inside the app, plain English transactional copy, friendly but precise tone, transparency about what is happening with the customer's money in real time) has become the global standard for consumer fintech and inspired Tide's business banking experience. Our designs translate that pattern to client-specific contexts: clear transaction descriptions over cryptic merchant codes, real-time push notifications written by a human (not the bank's legacy ledger system), in-app chat that reaches a real agent within target SLAs, and proactive communications when something has gone wrong (failed payment, blocked card, suspicious activity) before the customer notices. Content design follows the Monzo tone of voice public guide, adapted to client brand and FCA Consumer Duty plain language obligations.

The Online Safety Act 2023 places duties on user-to-user services and search services to assess and mitigate risks of illegal content and, for services likely to be accessed by children, content harmful to children. Ofcom is the enforcement regulator and is publishing codes of practice on a rolling basis through 2024 and 2025. Product design implications include age assurance flows (with the ICO Age Appropriate Design Code informing the UX standard), content reporting flows that are easy to find and use, transparency about moderation decisions, and safety-by-default settings for child users. Our designs for in-scope services produce a documented risk assessment input, age assurance UX aligned with ICO and Ofcom guidance, and reporting flows that meet the Act's accessibility expectations. We coordinate with client legal counsel and trust and safety teams from discovery.
