Web Dev & CRO questions UK buyers ask
How much does a custom website cost in the UK?+
Simple brochure sites start at £3,500. Most SME custom sites land between £6,000 and £18,000. Complex web apps with auth, dashboards and integrations are typically £20,000+ fixed-fee.
How long does it take to build a website?+
Brochure sites: 4-6 weeks. Mid-complexity sites with a CMS and integrations: 8-12 weeks. Web apps: 12-20 weeks. We work in fixed milestones with weekly demos.
What stack do you use?+
React/TypeScript on the frontend, Node or Cloudflare Workers on the backend, Supabase or Postgres for data. We pick the stack to fit your team — we don't lock you into ours.
Do you handle hosting and maintenance after launch?+
Yes — optional care plans cover hosting, security patches, uptime monitoring, weekly backups and a monthly improvement budget. Or you can take the code and host it yourself; everything we build is yours.
