Who we are
WebAnts is a London UI/UX design agency building Figma designs for startups, SaaS companies, and businesses that want a product their users can actually navigate.
We cover the full design stack — UX research, wireframes, information architecture, high-fidelity Figma designs, design systems, interactive prototypes, usability testing, and developer handoff. Every design project is handled by the same London-based designer from first wireframe to approved Figma file — no handoffs, no offshore teams.
Uniquely, WebAnts also builds what we design. If you want the same team to take your Figma designs into a production Next.js or WordPress build, we do that too — eliminating the briefing friction and fidelity loss that comes from handing a design file to a separate development agency.

Design services
UI/UX design services,
London.
Eight design services, all delivered in-house by the same London team. Figma-first. No handoffs to subcontractors.
01
UX Research & Discovery
User interviews, competitor analysis, persona development, and journey mapping to establish what your users actually need before a single wireframe is drawn. We run lean research sprints — 1–2 weeks — producing documented insights your entire team can use.
02
Wireframing & Information Architecture
Low-fidelity wireframes that establish page hierarchy, navigation flow, and content structure before visual design begins. Delivered in Figma, commented, and shared for async review. IA documents for complex multi-section products.
03
High-Fidelity Figma Design
Pixel-perfect Figma designs — desktop, tablet, and mobile — for every page and state. We use your brand guidelines (or build new ones) and present each screen for approval before moving to the next. No big reveals — continuous feedback.
04
Design Systems
Component libraries in Figma that scale with your product — colour tokens, typography scales, spacing systems, interactive component variants, and documentation. Built once, used consistently across every page and every future feature.
05
SaaS Product Design
Full product design for SaaS platforms: onboarding flows, dashboard UX, settings architecture, billing flows, and empty states. We design for the full signed-in product experience — not just the marketing site.
06
Web App UX Design
Complex web application UX — multi-step workflows, data tables, form sequences, role-based permissions, and admin interfaces. We specialise in reducing cognitive load for applications where users make frequent, consequential decisions.
07
Usability Testing
Moderated and unmoderated usability tests on live prototypes — identifying where users get confused, abandon tasks, or miss key functionality. We deliver annotated findings with prioritised recommendations. Most usability studies take 1–2 weeks.
08
Figma to Build Handoff
Design-to-development handoff in Figma — annotated specs, interactive prototypes, token documentation, and a development kickoff session. If WebAnts is building as well as designing, the handoff is internal — no friction, no briefing the same spec twice.

Design + build
Design and build,
under one roof.
Most design agencies hand off a Figma file. WebAnts hands off nothing — because the team that designed it builds it. Here is why that matters.
No briefing the same spec twice
When the designer and developer are the same team, the person who designed it builds it. There is no spec document that loses nuance in translation, no separate agency interpreting your brief differently.
Design decisions that are buildable
Designers who do not build sometimes produce designs that are visually impressive but technically impractical. Our designs account for how they will be built — animations, interactions, responsive behaviour, component structure — from the first wireframe.
Faster delivery
Running design and early build phases in parallel cuts timelines by 30–40%. You see staging updates during the design phase — not a two-month wait followed by a single reveal.
Design fidelity in the final build
When design and build share no handoff gap, the finished site matches the Figma file at pixel level. Rounded corners, spacing tokens, hover states, transitions — all preserved exactly.
One relationship, not two
Managing a separate design agency and a separate development agency doubles the project management overhead. One team, one point of contact, one invoice.
Post-launch design continuity
When you need a new feature, a new landing page, or a redesign of a key flow — the team that built it already has the context. No re-briefing, no catching a new agency up to speed.
From idea to live site in four steps.
Milestone payments — you see progress weekly and own every deliverable the moment it's completed.
Discovery Call & Flat Quote
Every project starts with a free 30-minute call — no pitch deck, no jargon. We ask the right questions about your goals, your audience and your budget, then deliver a written flat-fee proposal within 24 hours. You know the full cost before we touch a single wireframe.
- Free 30-minute strategy call
- Digital brief and business goal analysis
- Written flat-fee quote within 24 hours
- No hourly rates, no scope creep surprises
- Platform and technology recommendation included

FAQs
Common
questions.
What does a UI/UX design agency do?
A UI/UX design agency researches your users, designs the structure and visual interface of your website, web app, or SaaS product, and delivers pixel-perfect Figma files ready for development. UI (user interface) design covers the visual layer — typography, colour, spacing, components. UX (user experience) design covers the structural layer — navigation, user flows, information architecture, and usability. WebAnts is a London UI/UX design agency that handles both — and builds the final product as well, eliminating the design-to-development handoff entirely.
How much does UI/UX design cost in London?
UI/UX design in London from WebAnts starts from £2,000 for a design sprint (1–5 screens, 1–2 weeks). A full website design costs from £3,500 (2–4 weeks). Full SaaS product or web app design starts from £6,000 (4–8 weeks). All prices are flat fees — WebAnts provides a written quote after a free 30-minute discovery call. No prepayment required.
What is Figma and why do you use it?
Figma is the industry-standard design tool for UI/UX designers — a browser-based collaborative tool that supports wireframes, high-fidelity designs, interactive prototypes, design systems, and developer handoff, all in one file. We use Figma because it supports real-time collaboration (clients can comment directly on designs), produces accurate developer specs, handles interactive prototyping for usability testing, and is the tool our developers work from directly during the build phase. Every WebAnts design project is delivered as a Figma file you own.
What is the difference between UI and UX design?
UX (user experience) design covers how a product works — the navigation structure, user flows, information hierarchy, and the sequence of steps a user takes to complete a task. UI (user interface) design covers how a product looks — typography, colour, layout, iconography, and visual components. In practice, good product design requires both: a well-structured UX that is also visually polished. WebAnts handles both disciplines, starting with UX (wireframes, flows, structure) and finishing with UI (high-fidelity Figma designs).
How long does UI/UX design take in London?
A design sprint (1–5 screens) takes 1–2 weeks. A full website design takes 2–4 weeks. Full SaaS product or web app design takes 4–8 weeks depending on scope. WebAnts delivers approximately 1.8× faster than the UK design agency average — we run wireframing and early hi-fi design in parallel where possible, and you receive updates throughout the project rather than a single reveal at the end.
Can you design and then build my website or product?
Yes — and this is one of WebAnts' key differentiators. We design and build under one roof. The same team that creates your Figma designs builds the final product in Next.js, WordPress, or your chosen platform. This eliminates briefing friction, spec misinterpretation, design-to-build fidelity issues, and the project management overhead of managing two separate agencies.
Do you offer UX research services?
Yes. We conduct user interviews, competitor analysis, persona development, and journey mapping as part of our UX research sprint — typically 1–2 weeks. Research is available as a standalone engagement or as part of a full design project. We deliver documented findings your entire product team can use — not just raw interview transcripts.
What is a design system?
A design system is a shared collection of reusable UI components — colour tokens, typography scales, spacing systems, buttons, form elements, card components, and navigation patterns — documented in Figma and used consistently across every page and every future feature of your product. A design system ensures visual consistency, speeds up future design work, and gives developers a single source of truth for component specifications. WebAnts builds design systems in Figma as part of full website and SaaS product design projects.
Can you redesign my existing website while preserving my brand?
Yes. Redesigns are one of our most common projects. We audit your existing site for UX issues, conversion gaps, and SEO equity before starting design work. The redesign begins from your existing brand guidelines — or we refresh the brand identity as part of the project if needed. We map all existing URLs to new designs to preserve organic rankings through any structural changes.
Do you design mobile apps as well as websites?
We design web applications and progressive web apps (PWAs) that work on mobile — not native iOS or Android apps built in Swift or Kotlin. If your project is a mobile-first web app, a PWA, or a responsive SaaS product, we can design and build the full experience. For native app development specifically, we would recommend a mobile app specialist.
What does a UI/UX design project look like at WebAnts?
A WebAnts UI/UX design project follows four phases: (1) Discovery — a free 30-minute call to scope goals, users, and constraints, followed by a flat quote. (2) Research & Wireframes — user research (if in scope), information architecture, and low-fidelity wireframes in Figma for approval. (3) High-Fidelity Design — pixel-perfect Figma designs delivered screen-by-screen, each approved before we move to the next. (4) Handoff or Build — either a developer-ready Figma handoff or a direct build by WebAnts. No big reveals. Continuous feedback. You own every deliverable at each stage.
