If you, work for a construction company and you're wondering how much you’ll need to budget for a new website, the answer is:

It depends on what you need the website to do.

Each project will have different requirements. The scope, strategy, level of expertise and the allocated development time all influence the final cost.

So, this article is a guide to what a professional construction web design project costs, what you should expect for budgets of £15k, £20k and £30k, and how to work out which one is right for your business.

What separates a simple construction website from a strategic one?

It's not just how it looks.

What separates investment levels in website development is the depth of work that goes into understanding your business, goals for the website, your buyers, competitors and market before anything gets built.

It's what turns a good-looking website into one that generates leads, supports tenders, and grows a business.

At Bigfork, we work with construction companies across three investment levels. Here's what each one involves.

The Essentials: A well-designed bespoke construction website, from £15,000

This is everything you need for a professional website that supports tenders and looks good. It's what we call the ‘bread and butter’ of a B2B website.

In a project and price range like this one, you should expect a discovery session to understand your business, customers, and goals for the website.

It includes a bespoke design, mood boards to help you visualise it, and of course a quality build with an easy-to-manage CMS.

An example of a website at this budget is Bateman Groundworks, shown below.

Enhanced: A bespoke construction website with in-depth strategy for lead generation and tender support, from £20,000.

This is a website that gives you the competitive edge. It differentiates you from competitors, gives you visibility in search engines and ai overviews, and is optimised for conversions.

What you should expect at this price point, along with everything in the essentials tier:

Competitor website analysis to make sure you stand out
Comprehensive website strategy including positioning and value proposition
On site SEO and migration plan so you don’t lose your existing rankings
Conversion rate optimisation to get more quality leads from your website
Engagement and scrolling effects to keep visitors on the website longer. See an example of these on a site for Onyx Insight below.

If you want a site that helps to grow your company, this is the price point you should expect from a B2B website agency.

Premium: Full discovery including customer and stakeholder interviews, and premium engagement effects, from £30,000.

Why assume what your customers want from your website when you can ask them instead?

Customer and stakeholder interviews are worth the extra investment so you can understand what visitors really need from your website.

Speaking to stakeholders also helps with the development of your value proposition and positioning as you can find out how they already perceive your company.

This is included in our premium tier, as well as six months of website optimisation after launch.

What extra costs should you factor into a construction website design project?

The tier prices cover the design, build, and strategy work. But there are a few additional costs worth budgeting for from the start, incase you need them.

Content and copywriting

If you need copy written as part of the project, it’s a good idea to use a copywriter. Good construction website copy needs to speak to multiple audiences, balance technical credibility with clear benefits, build trust, and be written for search engine and ai visibility. A copywriter will save you time and get better results.

2. Photography and videography

Good imagery makes a significant difference to every web design. High-quality project photography, team shots, and site footage build immediate trust with the visitors on your website. It’s worth investing in a photographer or videographer to make your company stand out.

3. Extra branding work

Some companies opt to rebrand at the same time as a new website project. If your logo or brand guidelines need refreshing, this can be done by a design agency as a separate cost. It avoids the need to revisit the website further down the line if your branding is updated.

4. Hosting and maintenance

Once your website is live, it needs to be maintained and hosted securely. You can handle this yourself, but most web design agencies will offer this service afterwards. Letting your agency handle it reduces any risks involve with managing your site.

5. Ongoing improvements

The best construction websites are always improving. To help get the most out of yours, you may want to work with an agency who offer an ongoing website optimisation package. This way you can track its performance, monitor how visitors are behaving on your site, make ongoing SEO improvements, and test changes that improve your conversion rate.

If you're working with a professional construction web design agency, you should expect starting costs to range from £15,000 to £30,000 for a new website, depending on how much strategy, research, and discovery work goes into it.

The companies that get the best return are the ones that treat their website as a business development tool that generates enquiries, supports tenders, and pays for itself many times over.
