Leeds has become one of the UK’s most active fintech and digital hubs outside London, with a growing cluster of SaaS founders, agency spin-outs, and enterprise innovation teams working from the city centre and out towards Leeds Dock and the South Bank. If you’re building a SaaS product in Leeds, the biggest early risk isn’t code — it’s design decisions that lock in the wrong user flows before a single line of production software gets written. That’s where structured UX/UI design and prototyping earns its keep.
By Design UK works with Leeds-based founders and product teams to turn a rough idea or a messy spec into a clickable, testable prototype before committing to full-scale development. We sit deliberately between a solo freelancer and a traditional agency: you get senior-level design and product thinking, fixed pricing agreed up front, and AI-accelerated workflows that compress the timeline from concept to validated prototype — without the overhead of a large studio or the risk of a single contractor disappearing mid-project.
Leeds’ software scene spans everything from early-stage healthtech and legal-tech startups to established financial services firms modernising internal tools. Regardless of sector, the pattern is the same: teams that skip proper prototyping end up rebuilding core screens three or four sprints into development, burning budget that should have gone into features. A dedicated design and prototyping phase — wireframes, clickable prototypes, and usability testing with real users — catches those problems while changes still cost pennies, not thousands of pounds.
This work feeds directly into full SaaS build engagements, which typically range from £18,000 for a focused MVP to £650,000+ for enterprise-grade platforms with complex integrations, permissions, and compliance requirements. For teams building on Shopify rather than a bespoke SaaS stack, we also run design-informed Shopify projects from £499 to £18,999, and ongoing iteration is supported through support plans starting from £797/month for SaaS products or £299/month for Shopify stores.
Prototyping engagements in the UK generally sit between a few thousand pounds for a lean, single-flow clickable prototype and low-tens-of-thousands for a full design system covering multiple user roles, dashboards, and admin panels. The exact figure depends on the number of screens, whether you need original usability testing, and how much of the design needs to translate into a design system your developers can build against directly. We scope this as a fixed price before work starts, so Leeds teams know the full cost before committing — no hourly drift, no scope creep billed retroactively.
Most Leeds founders end up choosing between two flawed options. Freelance designers are often affordable and fast to start, but availability is inconsistent, quality varies wildly, and there’s rarely a proper contract governing IP or code ownership once the relationship ends. Traditional agencies offer more structure but come with long onboarding cycles, opaque day-rate pricing that balloons once “discovery” begins, and layers of account management between you and the people actually doing the work. By Design UK sits in the gap: fixed prices agreed before we start, senior design and development talent working directly with you, and a contract that guarantees full ownership of every file, prototype, and line of code we produce — no licensing traps, no vendor lock-in.
We don’t just design prototypes — we run our own live product. Tackly.co.uk is a multi-toolkit SaaS platform we built and operate ourselves, from initial UX prototyping through to production infrastructure and ongoing feature releases. It’s a working demonstration of the same fixed-price, AI-accelerated process we bring to client projects, and it means every recommendation we make about user flows, onboarding, and interface design is grounded in a product we maintain daily, not theory. We’re a UK-based team, we work on fixed prices, and every client keeps full source code ownership from day one.
While our office is based in Enfield, our design and development process is built for remote collaboration — the same setup that lets us run Tackly.co.uk as a live product. Leeds teams get structured video workshops, shared Figma boards, and async progress updates, so distance never slows down decision-making. If you’d like to see how we structure engagements or check our background, visit our about page, or get in touch directly via the contact page to scope your project.
Almost all of our work is delivered remotely via structured video workshops and shared design tools, which is how we run projects across the UK, including our own live product, Tackly.co.uk. In-person meetings can be arranged if genuinely useful, but they’re not required to get a high-quality outcome.
Yes. We regularly run design-only engagements on existing SaaS products, producing updated wireframes and prototypes that your existing team implements, or that feed into a phased rebuild handled through our SaaS development service.
A focused prototype covering core user flows usually takes two to four weeks, depending on complexity and how many stakeholder review rounds are needed. Larger design systems with multiple user roles take longer, and we agree a fixed timeline alongside the fixed price before starting.
Everything — Figma files, design systems, and any code produced — is handed over to you in full. There’s no licensing arrangement or dependency on us continuing the relationship, though ongoing iteration is available through our support plans if you want it.
