Key takeaways
Conversion improvement work for UK small businesses typically costs £500 to £3,000 for a focused project on existing pages, with audits at the lower end and page rewrites plus tracking at the upper. Ongoing monthly support costs more. These are indicative market ranges, not a price list: the right spend depends on what a conversion lift is worth to you.
- £500 to £3,000: focused conversion work on existing pages.
- £3,000 to £12,000: redesign of structure and key templates.
- £5,000 to £20,000+: full rebuild, only when the platform blocks fixes.
- Judge cost against the monthly value of a realistic lift.

Chat on WhatsApp →What does conversion improvement work include?
Conversion improvement work covers the changes that help a website turn more of its visitors into enquiries or sales. For a small business it usually includes tracking setup, a conversion audit, rewriting headlines and calls to action, adding proof and price guidance, simplifying forms, fixing mobile issues and measuring the effect.
What are typical UK market ranges?
Indicative ranges for UK small businesses, based on the market and on the scopes we see quoted. Prices vary with site size, platform and supplier.
- Tracking setup (GA4 key events, call and WhatsApp tracking): often a few hundred pounds.
- Conversion audit with a ranked fix list: roughly £500 to £1,500.
- Audit plus rewrites and fixes on top pages: roughly £1,500 to £3,000.
- Ongoing monthly conversion support: priced monthly, varying widely with scope.
- Redesign of structure and templates: £3,000 to £12,000.
- Full rebuild: £5,000 to £20,000 or more.
What drives the cost up or down?
Cost depends on how many pages need work, how easy the platform is to change, whether copy and photography are needed, how much tracking must be built, and whether testing is included. Sites on page builders or proprietary platforms often cost more to change.
- Number of pages and templates in scope.
- Platform: editable CMS versus developer-only changes.
- New copy, photography or video needed.
- Tracking complexity: calls, bookings, third-party tools.
- Testing: A/B tests add set-up and analysis time.

Chat on WhatsApp →How do you judge whether it is worth it?
Compare the cost with the value of a realistic lift. If a half-point conversion lift is worth £5,000 a month to your business, a £2,500 project pays back within weeks even if it only achieves half the target. If your site gets very little traffic, the same project may take years to pay back, and visibility should come first.
What should you watch out for?
Be wary of promised conversion rates, 'guaranteed' uplifts and packages built around tests your traffic cannot support. Ask what will be measured, how, and over what period. Make sure you keep ownership of your analytics accounts and any changes made.
What does this look like in practice?
A UK aesthetics clinic was quoted £14,000 for a new website to fix low bookings. A conversion audit found the booking link broken on some phones, no prices on treatment pages and reviews hidden on a separate page. A focused project in the lower range fixed all three, bookings rose, and the rebuild was deferred.
Conversion budget checklist
- Work out what an enquiry is worth.
- Estimate the value of a 0.5-point lift.
- Get quotes scoped by pages and deliverables.
- Ask what will be measured and for how long.
- Keep ownership of analytics and accounts.
- Start with an audit if unsure what is needed.

Frequently asked questions
How much does conversion rate optimisation cost in the UK?
For UK small businesses, focused conversion work on existing pages typically costs £500 to £3,000 as a project, with audits at the lower end. Ongoing monthly support costs more and varies with scope. These are indicative market ranges. Judge them against the value of a lift.
Is conversion optimisation cheaper than a new website?
Usually. Focused work typically costs £500 to £3,000, while a redesign costs £3,000 to £12,000 and a rebuild £5,000 to £20,000 or more in the UK market. A rebuild is only needed when the platform blocks the fixes. Start with an audit if unsure.
How do I know if conversion work is worth paying for?
Calculate what a realistic conversion lift is worth each month using your traffic, close rate and average sale. If the work pays back within a few months even at half the target, it is usually worth it. Otherwise, start with cheaper fixes.
Should I trust guaranteed conversion increases?
Be cautious. Results depend on traffic, offer and market, and no honest supplier can guarantee a specific rate. Ask instead what will be changed, how it will be measured and what similar clients achieved. Keep ownership of your analytics accounts.
