What you actually get for £10k versus £20k on a website

Most growing UK service businesses end up deciding between roughly these two budgets when they commission a new site. £10k feels like the sensible business choice. £20k feels like the proper investment. The difference between the two isn't twice as much site, and the lazy comparison treats it as if it is.

Here's the version that actually compares like for like, so you can tell which one fits what you're trying to do.

What's included at £10k

A £10k project for a UK service business in 2026 typically buys you a properly designed bespoke site, between 8 and 15 pages, built on WordPress or similar, with a sitemap shaped around how your customers actually buy. The design is original to you rather than templated, the build is solid, and the launch is supported.

What's usually not included at this level: original photography, video content, in-depth copywriting, deep discovery, or extensive post-launch optimisation. You're either supplying these yourself or going without.

The discovery phase is usually a single workshop, sometimes two, rather than a week of research. The copy is either provided by you, lightly edited by the agency, or written to a brief with one round of revisions. Photography is from your existing library or stock. Video is either skipped or limited to a single embedded asset.

A £10k project is the right level for a business that has its messaging mostly figured out, has decent existing photography, and primarily needs the site itself rebuilt to a higher standard. It's a competent answer to a contained problem.

What's included at £20k

A £20k project changes the shape of the work, not just the size. The page count might only go up by 5 or 10 pages, but what surrounds the build is significantly bigger.

You typically get a proper discovery phase, including stakeholder interviews, a content audit, and sometimes light user research. You get original photography on at least one shoot day, often two. You get copywriting support, either as a full service or as structured guidance and editing. You get a more involved design process with more rounds of refinement. You get a longer post-launch period where the agency is still actively working with you, not just bug-fixing.

The build itself is roughly the same as the £10k version in terms of complexity, sometimes a bit more sophisticated. The difference is everything around it. The £10k site is the build. The £20k site is the build plus the surrounding work that makes the build pay off.

This is the bracket where the visual content stops looking generic. Real photography of your team and your work, on your actual premises, doing your actual job, is the single biggest visible difference between a £10k and a £20k project.

Where the extra £10k actually goes

It's worth being specific about this, because the answer surprises most clients.

Roughly £2,500 to £4,000 of the difference goes on photography and video production. A photographer for a day, plus editing, plus sometimes a videographer for a half-day, costs real money and produces an asset that lifts every page on the site.

Roughly £2,000 to £3,500 goes on copywriting or copywriting support. Either the agency is writing significant amounts of copy for you, or they're providing structured guidance, briefs, and edits across multiple rounds. Either way, this is the part that fixes the messaging that the £10k project would have left alone.

Roughly £1,500 to £2,500 goes on a deeper discovery process. More stakeholder interviews, more analysis of the existing site, more time spent on the sitemap and the user journeys before any design happens.

The remaining £1,500 to £3,000 goes on the things that don't fit cleanly into a category. More design refinement rounds, longer post-launch support, more developer time on the things that are easy to underestimate, like form integrations, schema markup, or accessibility work.

Add it up and the £10k difference is mostly people, time, and content production. The build itself is a relatively small line in the gap between the two.

When £10k is really enough

A £10k project is the right call in a few specific situations. If your existing photography is really good and recent, you're saving the biggest line in the £20k version straight away. If your messaging is already clear and your team can write decent copy, you're saving the second biggest line. If you've already done strategic work on positioning and audience and you're confident in it, you don't need a deep discovery phase.

If all three of these are true for your business, a £10k project will get you a site that looks and performs almost identically to a £20k version. The extra £10k would be paying for things you've already got.

It's also the right call when budget really is the constraint and the choice is between a £10k bespoke site and not doing the project at all. A well-built £10k site is significantly better than a £4k template-based site, and the gap between them is usually bigger than the gap between £10k and £20k.

When £20k starts to earn its place

The £20k bracket earns its place when one or more of those three things is missing. If your photography is thin, dated, or stock-heavy. If your messaging hasn't been revisited in years. If you're not confident about who you're really for or what you should be saying to them.

It's also the right level when the website is really central to how the business gets leads. The post-launch optimisation work that's included at £20k pays itself back faster on a site that's doing real commercial work than on a site that's mostly a credibility marker.

The third case is when the team commissioning the project doesn't have time to do any of the surrounding work themselves. A £10k project relies on you bringing photography, copy, and content. A £20k project removes most of that load. For a marketing team that's already at capacity, that's worth real money.

The pattern we see most often

Across the projects we take on, the most common path is that the client comes in expecting to spend around £10k, the discovery surfaces gaps in photography or messaging that they hadn't planned for, and the realistic number ends up closer to £18k to £22k once those gaps are addressed.

The honest version of this conversation is that the £10k expectation was usually based on the build alone, and the things that would have made the build actually work weren't priced in. It's not that £10k is wrong as a number. It's that £10k for the build plus £8k of separate spend on photography, copy, and strategy is the same total as £18k for an integrated project, and the integrated version usually ships better.

The exception is the client who's already invested in the surrounding work. If you've recently had a brand refresh, recent photography, and a clear strategic position, £10k for the build is exactly the right number. Most teams aren't in that position.

How to decide

The simplest test is to look at the three things the extra £10k buys: photography and video, copywriting, and discovery. For each one, ask whether you've already got it covered or whether you're going to need it as part of the project.

If you've got all three, go with £10k. If you're missing one, you're probably looking at £14k to £16k once that gap is filled. If you're missing two or three, the integrated £20k project will almost certainly ship a better site for less total cost than trying to add them in piecemeal.
