If you've been quoted £4,000 for a 5-page custom website by a UK agency, the short answer is: it's probably fair, but it's worth knowing where the money goes. Most of it is real work. Some of it is overhead. A small slice is whichever side of the table is in a stronger negotiating position.
This post takes a typical UK £4,000 agency quote apart line by line, says what's reasonable, where to push back, and what a fair counter-offer looks like if you want to negotiate.
TL;DR
A typical UK 5-page custom website agency quote at £4,000 breaks down roughly as:
- £2,000 of actual work (designer + developer time)
- £1,000 of project management and account management
- £600 of agency margin
- £400 of workshops, kickoff phases, discovery sessions
The £2,000 of work is what you're paying for. The other £2,000 is the wrapper. For some businesses the wrapper earns its keep; for many UK SMBs it does not.
Line-by-line
Designer time, £600 to £1,000
Wireframes, visual design, two rounds of revisions. A UK designer at £400 to £600 a day takes 2 to 3 days to produce wireframes, visual design, and the revision rounds for a 5-page brochure site.
This is real work. Custom design is not template selection: it's deciding what goes above the fold, what order pages appear in, where the eye should land first, what the brand voice should sound like in 12 places across the site. Skipping this is what produces forgettable websites.
What to look for: revisions baked in (one or two rounds), not capped at "any change costs extra". A portfolio of recent work that doesn't all look identical (a sign the designer thinks rather than templates).
What to push back on: more than 3 days of design for a 5-page brochure is excessive unless the brief is complicated. £1,500+ of design time on a simple brief is the agency padding the number.
Developer time, £1,000 to £1,400
Build, deployment, testing, SEO foundations, contact form wiring. A UK developer at £400 to £600 a day takes 3 to 4 days for a 5-page Next.js or WordPress build.
This is also real work. The build is not just translating designs to code: it's the responsive behaviour at every breakpoint, the Core Web Vitals tuning, the structured data, the metadata, the accessibility baseline, the contact form delivery, the analytics setup, the deployment pipeline. Doing this properly is the difference between a site that ranks and one that doesn't.
What to look for: a specified stack (Next.js, WordPress, or similar) rather than "we'll figure it out". Core Web Vitals as a deliverable, not an aspiration. Source code in a repository the client owns.
What to push back on: more than 5 days of dev for a 5-page site is excessive. Anything over £2,000 of dev time is the agency padding the number or rolling stuff that should be quoted separately (e-commerce, CMS, integrations) into the headline.
Project and account management, £600 to £1,200
Status calls, scope tracking, change management, internal coordination. This is the line where the maths gets fuzzy.
In a real agency, project management is genuinely needed: the designer has to talk to the developer, both have to talk to the client, somebody has to track the deliverables against the agreed scope. The PM/AM time is what stops the project running 3 weeks over and £2,000 above quote.
In a small agency or a solo operation, the project manager is often the same person as the developer, which means you're paying for an internal seam that doesn't exist.
What to look for: a named contact who is your point of communication and a clear scope document that says what's in and what's out. If the agency has a dedicated project manager, ask whether you'd talk to them or to the designer directly. Both can be fine; the answer tells you about the agency's culture.
What to push back on: more than £1,200 of PM time on a 5-page brochure is overhead-heavy. If you're a solo decision-maker on the client side, you don't need a project manager translating between you and the designer. Push for direct contact.
Agency margin, £400 to £800
The agency is a business. It has rent, software subscriptions, accounting fees, insurance, and the partners' salaries to cover beyond the project hours. A 15% to 20% margin on the labour cost is normal and reasonable.
What to look for: a fixed-fee quote that doesn't quietly rebill the project at 1.5x if it runs over. Margin is fair; surprise change orders are not.
What to push back on: padding via "contingency budgets" of 25%+ that get spent regardless of whether the project goes smoothly. A fair contingency is 10%; anything more is the agency hedging too much.
Workshops and discovery, £200 to £600
Kickoff session, brand discovery, audience workshop. For complex briefs with multiple stakeholders, these earn their keep: getting marketing, sales, and leadership aligned on what the site should do is genuinely valuable.
For a 4-person UK accounting practice where the partner is also the marketing director, kickoff workshops are theatre. The partner already knows what the site needs to do; the workshop produces a deck restating it.
What to look for: a workshop with specific deliverables (audience personas, content brief, success metrics) rather than a vague "alignment session".
What to push back on: more than £500 of pre-build workshops on a simple brief. If you're a single decision-maker, ask whether the workshop can be a 90-minute call instead. Most agencies will accommodate.
What a fair £4,000 quote looks like
The line items add up like this for a fair quote on a typical 5-page UK SMB brochure site:
- £800 designer (3 days, two revision rounds)
- £1,200 developer (4 days, including SEO and accessibility baseline)
- £800 PM/AM (one named contact, weekly check-ins, scope tracking)
- £600 agency margin (15%)
- £400 kickoff workshop and discovery
- Total: £3,800
If the quote is materially over £4,000 for the same scope, the agency is loading PM time, padding the build hours, or rolling in things that should be separately priced (e-commerce, CMS, custom integrations). If it's under £3,500, the agency is either competing on price or skipping things that should be in scope. Both are signals worth investigating.
When to walk away
Three signals that the quote is not fair:
- No fixed scope. A "time and materials" quote on a 5-page brochure site means the agency is reserving the right to bill more if things take longer. Push for a fixed-fee number with a clear scope document.
- No code handover. If the agency keeps the source code and won't release it on project completion, you're renting the website, not buying it. This is increasingly rare but still happens at older WordPress shops.
- Hosting tied to the build. If the only way to host the site is on the agency's infrastructure (at a markup), you're locked in. Insist on a portable build that can run on your own hosting or any cloud provider.
The alternative most quotes don't mention
The £4,000 upfront cost is the standard agency model, but it's not the only model. A pay-monthly plan (e.g. £50 a month for 24 months) recovers the same build cost over time, with hosting and small edits included. £1,200 over 24 months versus £4,000 upfront plus £50 a month hosting.
The trade-off is the 24-month commitment. The upside is the cash position on day one, which is the reason most SMBs put the £4,000 quote in the drawer.
So, is £4,000 fair?
Probably. If the line items add up roughly as above and the scope is clearly defined, you're paying market rate for a custom UK website. Where to push back is on the wrapper, not the work.
If the upfront cost is the blocker rather than the fairness, the question isn't whether £4,000 is fair, it's whether there's a payment shape that works for you. There usually is.
If you've got a quote you want a second opinion on, bring it to the bureau's discovery call. Fifteen minutes, honest steer on which parts are worth paying for and which the £50-a-month plan covers without them.
