Ask a UK web agency how long a website takes to build and the answer is almost always some variation of: it depends, probably six to eight weeks, give or take. For most small businesses, a new website should take two to four weeks from kick-off to going live. The reason so many take three to six months has less to do with the work involved and more to do with how agencies structure — and protect themselves within — their projects.
What each stage of the build actually takes
A standard small business website — five to ten pages, clear navigation, mobile-first — does not require months of work. Here is where the time genuinely goes.
Discovery and briefing: 1–3 days
Understanding your business, your customers and your competition takes a few hours of focused conversation. Agencies that stretch this to two weeks are billing time they would otherwise spend finding their next client.
Design: 3–7 days
A skilled designer can produce a finished site design in three to five days. Multiple rounds of revisions exchanged over email can extend this indefinitely. Fixed-scope projects avoid this by defining revision rounds in the contract before work starts — one round, then approved.
Development: 5–10 days
Converting a design into a working, tested, fast-loading website takes roughly a week for a standard small business site. More for custom integrations; less if the tech stack is well-chosen and the developer is experienced in it.
Content and copy: 1–5 days
The biggest variable most businesses do not plan for. If you have not supplied copy and images, the build cannot finish. Businesses that have content ready before kick-off consistently launch faster. Delays here almost always sit on the client side, not the agency's.
Testing and launch: 1–2 days
Cross-browser and mobile testing, form testing, DNS transfer and propagation. Fast with a structured process; slow without one.
Why most agencies take 8–16 weeks
Several structural reasons account for the gap between what a build actually requires and how long it takes:
- Running multiple simultaneous projects. A ten-person agency with twenty active clients is context-switching constantly. Your project enters a queue and rises when capacity allows.
- No fixed process. Open-ended discovery, unlimited revision rounds and stakeholder sign-off at each stage produce flexibility — and indefinite timelines follow from that flexibility.
- Slow approval loops. Every time a design goes back for client review and the client takes two weeks to respond, two weeks are added. Most agencies factor this in by padding estimates rather than tightening the process.
- No contractual deadline. A written go-live date creates accountability. A range with a qualifier does not.
How a 14-day scope works in practice
At WebArrow, every project is scoped for a two-week delivery. This is not a headline — it is a structural constraint that forces better decisions throughout the build.
The scope is fixed before kick-off: five pages, defined deliverables, agreed content. Day one is kick-off; the content brief goes to the client on day one with a 48-hour deadline for copy and images. Design starts in parallel. Development begins the moment design is approved — which happens once, not in rounds. Day fourteen is launch.
This works because additions to scope go into a separate brief for after launch, not into the live project. The result is a site that is live, performing and ranking in two weeks rather than a design that has been revised eleven times and is still not in a browser.
What you can do to accelerate any build
These four things make the biggest difference to delivery speed, regardless of who you work with:
- Have your core copy ready before kick-off. A one-page brief covering your offer, your services, your prices and a short paragraph about your business is enough to start.
- Have your images ready. A logo in vector format and six to eight photos of your team, premises or work can cut days off the timeline.
- Designate one decision-maker. If approvals require three people who do not share a calendar, delays follow.
- Be specific. A reference site you like, a colour palette and a list of must-have features is a brief. Something clean and modern is not.
The honest timeline by type of build
- Fixed-scope build with a contractual deadline (e.g. WebArrow Starter Website): 14 days
- Experienced freelancer with organised client and content ready at kick-off: 3–5 weeks
- Small agency with a defined internal process: 6–10 weeks
- Mid-size agency with full discovery and multiple approval stakeholders: 10–16 weeks
A site that is live and generating enquiries in two weeks is worth more than a design that is still in review in month three. If you want to know what your current site is costing you in missed enquiries while you weigh up your options, run the free audit.
