Invisible Costs: What Most Quotes Hide

1. Project Management (10–15 % of budget)

Keeps designers, developers, and stakeholders aligned—cheap to overlook, costly when missing. What affects website design price?

2. Quality Assurance & Accessibility (5–8 %)

Cross-browser testing, WCAG 2.2 checks, performance audits; failure here invites legal risk and ranking drops.

3. Licences & Tools (variable)

Premium Webflow plugins, stock libraries, email API credits—small individually, substantial over a year.

4. Post-Launch Maintenance (15–20 % of build cost annually)

Bug fixes, security patches, CMS updates. UK average sits between 15 % and 20 % of the initial spend.

How Agencies Build a Quote

1. Discovery Workshop (5–10 %): defines goals, user personas, site architecture.
2. Design Sprint (20–25 %): mood boards, prototypes, feedback loops.
3. Build Phase (40–50 %): coding, CMS population, integration tests.
4. Optimise & Deploy (10–15 %): SEO hardening, Core Web Vitals tuning.
5. Warranty & Care Plan (5 %): 30-day bug-fix guarantee, monthly updates.

Insight: A transparent quote pegs every pound to an outcome; if you can’t trace the benefit, question the line. Learn more about website cost in the UK here.
