Construction Company Website Cost: Budget Guide 2026

A properly built construction company website costs between £2,000 and £20,000+ depending on scope, tech stack, and how much content management capability the business needs. A CMS-managed site with a project portfolio, services pages, and a contact/quote flow — the standard for any firm with an active project pipeline — typically lands in the £5,000–£12,000 range. Template-based builds on Wix or Squarespace come in under £2,000 but carry ongoing dependency costs. Custom Next.js builds with a headless CMS sit at the higher end and deliver lower total cost of ownership over a 3–5 year lifespan.

Here's the full breakdown of what drives cost and how to evaluate the quotes you receive.

I recently completed a website build for Lankes.si, a construction company in Slovenia. The project covered a full CMS-managed site with a filterable project portfolio, services structure, multilingual routing, and a contact flow built for the way the business actually receives inquiries. Going through that build end-to-end gave me a clear view of where construction website budgets go, what's often excluded from agency quotes, and what a construction firm should realistically expect to pay for a site that works for 3–5 years without constant developer involvement.

The Three Tiers of Construction Website

Every construction website build fits into one of three categories. Here's how they compare on the dimensions that matter for a construction business:

Tier 1 — DIY / Template builders (£500–£2,000)

Wix, Squarespace, and WordPress page builders get a site live quickly. For a sole trader or a construction firm with fewer than five active projects, this tier is a reasonable starting point. The tradeoff shows up over time: platform-locked content means migration is painful later, performance at scale is inconsistent, and adding a proper CMS-managed project portfolio requires workarounds that don't age well.

Tier 2 — WordPress agency build (£2,000–£8,000)

The most common quote a construction company receives. Familiar technology, large talent pool, faster builds. The practical challenge for construction firms is that WordPress portfolio setups rely on a stack of plugins — Advanced Custom Fields, WooCommerce for quote flows, WPEngine or similar for hosting — each of which introduces a maintenance dependency. Security patches, PHP version updates, and plugin compatibility issues accumulate. A firm that expects to add ten new project pages per year will either pay a developer for each one, or learn to navigate the WordPress admin well enough to do it themselves (which is genuinely achievable, but requires a thorough handover).

Tier 3 — Custom Next.js + headless CMS (£6,000–£20,000+)

Higher upfront cost for a cleaner outcome. The CMS is purpose-built for the content the business actually manages — projects, services, team, testimonials — rather than adapted from a blogging platform. Performance is built in at the architecture level. The client can add new project pages, update service descriptions, and publish case studies from a structured admin interface without opening a code editor. Over a 5-year lifespan with regular portfolio updates, this tier typically costs less in total than a WordPress build with ongoing developer retainer fees. For a construction firm doing £3M+ in annual revenue, the content system is an asset worth investing in properly.

What Actually Drives the Cost

Within each tier, several line items move the final number significantly:

Number and complexity of pages. A 10-page site (home, about, services overview, 3–4 service detail pages, project portfolio, contact) costs materially less than a 25-page site with individual location pages, a team directory, and a case study archive. Get clear on page count before comparing quotes. More on what pages a construction website should include in this article.

Portfolio complexity. A static gallery of project photos costs almost nothing to build. A CMS-managed portfolio with filterable categories (commercial, residential, fit-out), individual project detail pages, and client testimonials per project is a meaningful build. The difference in quotes between these two implementations can be £2,000–£4,000. Know which one you're quoting for.

Inquiry and quote flow. A basic contact form takes an hour to build. A multi-step quote flow with project type selection, budget range, timeline, and file upload — the kind that actually pre-qualifies leads — requires proper design and conditional logic. Budget £500–£1,500 more for this if it's in scope.

CMS setup and client training. A good build includes a handover: documented admin workflows, training video or session, and enough time for the client to actually learn to manage their own content. Agencies that don't include this are planning for ongoing dependency. Ask explicitly what's included in the handover.

Photography and copywriting. Almost universally excluded from web development quotes. Professional photography for a construction portfolio runs £500–£1,500 per shoot. Copywriting for services, about, and project pages runs £500–£2,000 depending on volume. If you're comparing quotes and one includes copy and photography and another doesn't, they're not comparable numbers.

Hosting and support post-launch. A managed hosting plan for a Next.js site on Vercel runs £20–£100/month depending on traffic and plan. A WordPress site on WPEngine or Kinsta runs £25–£80/month. Support retainers — the kind that cover "can you add this to the services page" requests — range from £100–£500/month depending on what's included. Factor 12 months of these costs into your year-one budget.

SEO setup. A developer who sets up schema markup (LocalBusiness, FAQPage, breadcrumbs), a proper sitemap, meta title and description fields in the CMS, and canonical tags is doing meaningful SEO work that most template builds skip. This is worth paying for once at launch.

What You're Actually Buying

A construction website isn't a one-time purchase — it's a content system the business will run for the next 3–5 years. During that period, the firm will complete new projects worth showing, add team members, update services, and potentially expand into new regions or trade categories. The real cost question is what the total cost of ownership looks like across that full period, including the time and money spent getting content updates done.

A site where a project manager can log in and add a new project — photos, description, category, client name — in 20 minutes is worth more than a site that requires a developer call every time the portfolio needs updating. Multiply that developer call by 15–20 portfolio additions per year, at £75–£150/hour each, and the CMS investment pays for itself inside 18 months.

This is the argument behind a proper headless CMS setup with Payload: the admin interface is structured around the content types the business actually manages, not adapted from a generic publishing platform. The content editor sees "Project Title", "Category", "Completion Date", "Photos" — fields that map to the business, not to a blog post model from 2005.

Lankes.si — A Real Example

Lankes.si is a construction company in Slovenia. The project scope included:

• Home, About, Services (overview + individual service pages), Project Portfolio, and Contact
• A CMS-managed filterable portfolio with individual project detail pages, built on Payload CMS
• Multilingual routing for Slovenian and German markets
• A structured contact/inquiry flow mapped to how the business handles inbound leads
• SEO setup: schema markup, sitemap, meta fields editable from the admin
• Client handover with documentation

The tech stack was Next.js (App Router) + Payload CMS, deployed on Vercel. This puts the build firmly in Tier 3 — the higher upfront cost, in exchange for a system the client operates independently and a codebase that will scale cleanly as the business grows.

Without getting into exact figures (which vary by market and scope), a project of this complexity falls in the £8,000–£14,000 range in the UK/EU market. The client can now add new projects, update services, and publish content without developer involvement. That independence was the central requirement from the start, and the tech choices were made to serve it.

What to Watch Out for in Quotes

A few patterns that show up regularly in construction website quotes worth knowing before you sign anything:

Photography and copy excluded. Most quotes cover design and development only. A quote for £4,000 that excludes copy and photography isn't cheaper than a £6,000 quote that includes them — it's a different scope. Ask explicitly what's in and what's out.

Maintenance retainers that cover basic content updates. If the site is built properly, you shouldn't need a retainer to add a project page. A retainer covering security patches, uptime monitoring, and CMS version updates is reasonable. A retainer covering "I need to update my portfolio" is a sign that the CMS handover wasn't done properly.

Portfolio features that are actually static HTML. Some agencies quote a "portfolio section" that's a hardcoded grid of images with no CMS. Ask specifically: can I add a new project myself, and what does that process look like? If the answer involves sending files to a developer, it's a static gallery.

Ranges so wide they're useless. "£2,000–£50,000 depending on requirements" is not a quote — it's a placeholder. Push for a scoped estimate with specific deliverables listed, or provide a clear brief (page count, CMS requirements, any integrations) and ask for a fixed-scope number.

Frequently Asked Questions

How much does a construction company website cost?

A construction company website built to a professional standard costs between £2,000 and £20,000+ depending on scope and technology. A CMS-managed site with a project portfolio, services, and contact flow typically falls between £5,000 and £12,000. Template-based builds on Wix or Squarespace cost less upfront but carry higher long-term maintenance and dependency costs.

What is included in a construction website build?

A complete build includes design, development, CMS setup, content migration or entry, SEO setup (schema, sitemap, meta fields), and client handover. Photography and copywriting are usually quoted separately and add £1,000–£3,000 to the total. Hosting and support are ongoing monthly costs, typically £20–£150/month.

Is WordPress good for a construction company website?

WordPress works well for construction websites in the £2,000–£8,000 range, particularly for smaller firms. The main limitation for construction-specific use is that a portfolio with CMS-managed project pages requires a plugin stack that accumulates maintenance overhead over time. A headless CMS purpose-built for the content types the business manages is a cleaner long-term solution for firms with active, regularly updated portfolios.

How much does website maintenance cost for a construction company?

Hosting runs £20–£100/month depending on platform and traffic. A support retainer covering security patches, updates, and minor content work runs £100–£300/month. A properly built site with a good CMS handover reduces the need for a developer support retainer, since the business can manage most content updates independently.

How long does it take to build a construction company website?

A Tier 1 template build can go live in 1–2 weeks. A Tier 2 WordPress agency build takes 4–8 weeks. A Tier 3 custom Next.js build with a headless CMS typically takes 6–12 weeks, including design, development, CMS setup, content population, and client review rounds.

Can I update my construction website without a developer?

On a well-built Tier 3 site with a headless CMS, yes — adding new projects, updating services, editing team pages, and publishing case studies are all tasks the client handles independently via the CMS admin. On a Tier 2 WordPress build, it depends on how the portfolio is structured. On a Tier 1 template build, basic updates are possible but portfolio management can be limited.

Conclusion

The most useful question to ask before signing a construction website quote isn't "how much does it cost?" — it's "what is the total cost of ownership over three years, including my time?" A cheaper upfront build that requires a developer for every portfolio update costs more in practice than a properly built CMS site where the business runs its own content.

Real numbers, from a real construction website project: a Next.js + Payload CMS site with a full CMS-managed portfolio, multilingual routing, and SEO setup lands in the £8,000–£14,000 range. That scope is appropriate for a construction firm with an active portfolio and plans to grow. Smaller firms can start at £3,000–£6,000 with a WordPress build and migrate later. The key is knowing what you're buying at each tier before comparing quotes.
