How Long Does It Take to Build a Website? (Belfast Business Owner's Guide)

It's one of the first questions Belfast business owners ask when they start thinking about a new website: how long is this going to take? The honest answer is: it depends — but in a useful, specific way. Here's what actually determines the timeline, what a realistic schedule looks like, and how to make sure your project doesn't drag on longer than it should.

The short answer

For a typical small business website in Belfast — 5 to 10 pages, no ecommerce — expect 6 to 10 weeks from the first conversation to launch, assuming the process runs smoothly.

For ecommerce, complex integrations, or a larger multi-page site, budget 10 to 16 weeks.

These are realistic timelines at a professional agency. Be wary of anyone promising a full professional website in two weeks unless it's a template build with minimal customisation.

The four phases and how long each takes

Phase 1: Discovery and briefing (1–2 weeks)

Before a single page gets designed, a good agency needs to understand your business. Who are your customers? What do you want visitors to do? What does your existing site do well, and where does it fall short? What are your competitors doing?

This phase involves a briefing call (usually 60–90 minutes), often a questionnaire, and a review of any existing assets — logos, photography, copy, brand guidelines. If you come to this phase prepared and responsive, it moves quickly. If feedback takes two weeks to come back, it takes two weeks.

Common delay: The client hasn't gathered the necessary assets (logos in vector format, photography, copy documents) before the project starts.

Phase 2: Design (2–4 weeks)

The design phase turns the brief into visual pages — layouts, typography, colours, how content is organised. A good agency will typically show you wireframes or low-fidelity mockups first, then move into full visual design once structure is agreed.

For a 5-page site, this phase typically runs 2–3 weeks. Larger sites, or sites where the brand is being developed alongside the web design, can take 4–6 weeks.

Common delay: Multiple rounds of feedback because stakeholders weren't aligned on the brief at the start. The best way to avoid this is to have one decision-maker on your side who can give clear, consolidated feedback.

Phase 3: Build (2–6 weeks)

Once design is approved, the build phase turns the visuals into a live, functional website. This is the most technically complex part of the process and where agency experience matters most.

A simple brochure site on a modern platform like Framer or Webflow can be built in 2–3 weeks. A WordPress site with custom functionality, or a Shopify store with a large product catalogue and third-party integrations, can take 4–8 weeks.

Common delay: Late additions to scope ("can we also add a booking system?") and slow client sign-off on design before build begins.

Phase 4: Testing, revisions, and launch (1–2 weeks)

Before your site goes live, it needs to be tested — on mobile and desktop, across browsers, for load speed, for broken links, and for any accessibility issues. A thorough agency will also do a technical SEO review before launch to make sure the site is indexed correctly.

Revisions from testing add time, especially if significant issues are found. Budget 1–2 weeks for this phase.

Common delay: Clients requesting significant changes at this stage that require going back to the design phase.

What you can do to keep the project on track

The number one cause of project delays is client-side: slow feedback, unclear briefs, and last-minute changes. Here's how to be the client that gets their site delivered on time:

• Appoint one decision-maker — the person whose approval the agency needs. Multiple stakeholders with different opinions will slow you down significantly.

• Gather assets before you start — logos in vector or high-resolution format, photography (or a clear decision to commission it), any existing brand guidelines, your best examples of copy.

• Give feedback within 48 hours — agencies work to schedules, and slow feedback pushes your project back in the queue.

• Agree scope before signing — every addition mid-project extends the timeline. If something comes up, discuss how it affects the schedule.

• Trust the process — good agencies have a methodology. Asking to skip wireframes or jump straight to final design usually leads to more revisions, not fewer.

A note on "quick" websites

You'll find services offering a professional website in a week. Some of these are template-based builds that can look good but won't be tailored to your business or optimised for search. For some businesses — particularly those just getting started — that's fine. But if you want a site that reflects your brand properly, ranks well in Belfast for your services, and is built to convert visitors into customers, that takes longer.

A well-built website is an asset that should serve your business for 3–5 years. Getting it right is worth the time.
