How much does a custom WordPress site cost in 2026 for a UK B2B service business?
Concrete brackets, updated Q2 2026. £7,500 — £24,000 for marketing sites in the chosen ICP.
Concrete brackets, updated Q2 2026, for UK B2B service businesses with one to three locales and a clear ICP. Numbers below are fixed-bid, not “starting at” theatre.
The brackets
- £7,500 — £12,000 · Marketing site, one locale, custom theme on Gutenberg, four to six template types, conformance to WCAG 2.2 AA on launch. 4 — 6 week build window.
- £12,000 — £18,000 · Same as above plus a second locale, ACF-driven editorial workflow, headless analytics endpoint, and a published runbook for the in-house team.
- £18,000 — £24,000 · Three locales, regulated-copy editor lock-down (role-based block permissions), Salesforce/HubSpot integration, EAA conformance documentation pack.
What changes the price
Editorial parity (how many existing pages, how strict the layout fidelity), accessibility evidence (axe alone is £0; manual NVDA on five locales is £2,000), and integration count. Brand work is not in scope — that’s a separate engagement with a separate vendor.
What doesn’t change the price
The plugin license cost (you pay direct), hosting (you pay direct, I recommend Kinsta or WP Engine), and content production (your team writes).
