Builder website cost: UK prices for 2026

A builder website costs £400-£1,500 for a one-off build, £2,500-£5,000 from an agency, or £49-£199 a month for a managed plan. For a building firm the design barely matters. The project gallery does everything, because someone about to hand over £40,000 for an extension is buying evidence you can finish.

A builder I know had a genuinely ugly website. Bad fonts, dated layout. It also had sixty photos of completed extensions across his patch, each with the town named. He was booked eight months out. His competitor had a beautiful site with four stock images. Guess who got the enquiries.

The routes and what they cost

For most building firms the agency column is money spent in the wrong place. £3,500 on design and £0 on ever updating it produces a lovely site that is three years stale by the time it matters.

The gallery is the whole product

Everything else on a builder’s website is supporting cast. Get this right and a mediocre site outperforms a beautiful one.

What a good project gallery has:

• Before and after on the same job. The before shot is what sells. Nobody believes an after photo on its own.
• The town named. “Two-storey side extension, Harrogate” tells Google where you work and tells the reader you work near them.
• The scope in one line. What you did, roughly how long it took. Not an essay.
• Enough of them. Twenty projects reads as an established firm. Four reads as a new one, whether or not that is true.

That is it. Photos taken on a phone are fine. Clients are looking at the brickwork, not the photography.

What else earns its place

Short list. A builder does not need fifteen pages.

The trades you do and do not do. Extensions, loft conversions, renovations, groundwork, new builds. Say what you turn down too. It saves calls.

Named areas. “Builders in Chelmsford, Braintree, Witham and Maldon” beats “Essex and surrounding areas” by a mile, both for Google and for the reader wondering if you travel to them.

Insurance, memberships, guarantees. FMB, TrustMark, public liability cover, structural warranties where relevant. On a £40,000 decision this is what settles nerves.

Reviews as text on the page. Google reviews pulled through, or quoted with a first name and town.

A price indication. Not a price list. A range for typical jobs. It costs you the enquiries you never wanted and keeps the ones you did.

Where the ongoing money goes

If you pay once and never touch it, your gallery freezes at whatever you had in launch week. Two years on, your best work is invisible and your site says you are a firm that stopped working.

The monthly version is mostly gallery upkeep and local pages: new projects added, new areas targeted as you expand, the Google Business Profile posted to, reviews chased after each job. It is not glamorous work. It is exactly the work that keeps a builder visible.

At £49-£199 a month against a single extension at £40,000, the arithmetic is not close. One extra job every few years covers a decade of it. Nobody can promise you jobs though, and if a provider guarantees you leads, that tells you what kind of provider they are.

Which should you actually pick

Pay once if your diary is full from referrals, you have a good reputation locally, and you just need somewhere for referred clients to check you out. £700 to a decent freelancer, add photos yourself when you remember, keep your Google profile current. Perfectly sensible.

Pay monthly if you want work you do not currently get, if you are expanding into a new area, or if you know you will never get round to updating it yourself. The last one is the real reason for most builders. It is not that you cannot, it is that you are on site at 7am and doing quotes at 9pm.

The trade-wide picture is in online presence for builders, and the same cost breakdowns for related trades are in plumber website cost and electrician website cost.

Our plans are £49, £99 and £199 a month, rolling, and you own the domain and everything on the site. Most building firms want the £99 tier. The pricing page sets out the scope, or tell us your patch and what you build and we will say which one fits without the sales routine.
