Web Design agencies in Milton Keynes.

A brochure or small marketing site usually runs 6-10 weeks end to end. Ecommerce builds take 10-18 weeks depending on catalogue size and integrations. The phases sit roughly: 1-3 weeks discovery, 2-5 weeks design, 2-8 weeks build, 1-2 weeks QA and launch. Strategy-led or multi-stakeholder programmes commonly quote 4-6 months. Content readiness and approval speed on the client side tend to push timelines more than design or development capacity.

Web Design is the visual and user-experience work: research, information architecture, wireframes, brand application, UI design, and interactive prototypes. Web Development is the technical build that turns those designs into a working website: code, CMS configuration, integrations, performance, accessibility, and shipping to production. Some UK agencies cover both under one roof, others specialise. Either model is fine, but knowing which discipline is being commissioned avoids paying design rates for build work or build rates for design work.

It depends on the brief. WordPress remains the volume default for content-led marketing sites and the cheapest to run long term. Webflow and Framer suit design-led marketing sites with smaller content needs. Shopify is the default for commerce up to mid-market. Custom React or Next.js paired with a headless CMS such as Sanity or Contentful costs more up front but wins on performance and flexibility. A credible agency recommends the platform, not a preferred default.

Three shifts matter. AI tools such as Figma AI, v0, and Cursor have compressed the production layer, so the fee now sits in strategy, UX judgement, and quality control rather than asset output. The European Accessibility Act, in force from 28 June 2025, makes WCAG 2.1 AA (with 2.2 AA the working target) an expectation for UK sites selling into the EU. Core Web Vitals remain a Google ranking signal, so performance is a design decision, not a post-launch fix.
