Key Takeaways

A plain-English pricing guide for firms that want enquiries — not just a brochure.

Are you confused by website quotes ranging from £500 to £25,000 — and wondering which one’s actually right for your firm?

Why do some professional services firms pay thousands for a new site, only to end up with something that looks good but generates no new enquiries?

This guide explains exactly what drives the cost of a professional services website in the UK, what to expect at different price points, and how to budget in a way that delivers measurable ROI.

By the end, you’ll understand:

  • Typical website cost ranges for professional services firms
  • What drives price up or down (and hidden costs to avoid)
  • The difference between brochure sites vs enquiry systems
  • Questions to ask any provider before signing a contract
  • Real-world examples of firms who turned websites into enquiry engines

The Short Answer

  • Basic DIY website: £500–£1,500
  • Conversion-ready website: £4,500–£9,500
  • Full growth system (website + marketing engine): £10,000–£25,000+

The real question isn’t “How much does it cost?” but “How soon will it pay for itself?”

What Drives the Price (and Why It Varies)

  • Scope & pages (service areas, practice hubs, FAQs, location pages)
  • Content (professional copywriting, photography, thought-leadership)
  • Conversion design (layouts, CTAs, booking flows, enquiry forms)
  • Integrations (CRM, calendars, payments, marketing automation)
  • Compliance & trust (GDPR, accessibility, accreditations, reviews)
  • Migration & SEO (redirects, site speed, structured data, Core Web Vitals)

Tip: If a quote is very cheap, check what’s missing from this list. That’s usually where the “cost” hides.

Three Common Packages (and What You Actually Get)

PackageSuitable forWhat’s includedTypical Investment
Starter “Credibility” SiteNew/solo practices, referral-driven firmsBranded template, 5–8 pages, basic forms, light SEO, DIY content£1,500–£4,000 (one-off)
Conversion-Ready WebsiteEstablished firms wanting steady enquiriesStrategy, conversion design, copywriting for key pages, reviews/case studies, local SEO, CRM/form routing, analytics, launch checklist£4,500–£9,500 (one-off)
Growth System (Website + Engine)Growth-focused firmsEverything above plus lead magnets, landing pages, blog setup, schema, advanced tracking, automation, nurture sequences, retargeting campaigns£10,000–£25,000+ (project)

Tip: If budget is tight, fix conversion first (so existing traffic enquires), then layer in SEO, then scale with ads/social.

One-Off vs Ongoing Costs

One-off (build): as per the packages above.
Ongoing (performance):

ItemTypical Ongoing
Hosting£10–£50/month
Care plan (updates, fixes)£79–£249/month
Licences (plugins/tools)£0–£50/month
SEO/content (optional)£600–£2,500+/month
Ads management (optional)£500–£2,000+/month + ad spend

Tip: SSL certificates should be free (via Let’s Encrypt). Don’t pay extra for basic HTTPS.

ROI: Brochure Site vs Enquiry System

Website TypeWhat You GetROI Impact
Brochure WebsitePolished design, 5–8 pages, light SEO, minimal conversion toolsLow — looks credible, but generates few enquiries
Conversion-Optimised WebsiteStrategy, SEO, CRO, reviews, enquiry tools, CRM integrationHigh — consistent enquiries, measurable ROI, pays for itself in months

Example: If one new client per month is worth £1,200 in margin, an extra 2–3 enquiries per month covers a £7–9k site quickly.

Proof in Practice

Fountain Solicitors – Their old “brochure” site looked professional but delivered few leads. After relaunching with strategy, SEO, and conversion tools, they now generate 60+ enquiries per month and scaled from 1 to 5 offices.

Hair by Imad – Already reputable, but invisible online. By fixing SEO + conversion pathways, bookings increased by 700% from organic search.

Conclusion: How Much Should You Spend?

  • If referrals drive most of your work → Starter Site is fine.
  • If you want predictable enquiries → Conversion-Ready Website is the minimum.
  • If growth is the goal → invest in a Growth System so marketing can compound.

Final Thought: A “cheap” site is expensive if it generates no enquiries. The right site pays for itself — and keeps paying back.

FAQs About Professional Services Website Costs

What’s the average cost of a professional services website in the UK?

Most established firms spend £4,500–£9,500 for a conversion-ready site.

Why do some websites only cost £500 while others cost £20,000+?

Cheaper sites skip essentials like copywriting, SEO, compliance, and tracking. High-value builds include these to generate enquiries, not just look good.

Do I need to pay monthly for my website?

You’ll have hosting, care, and licence costs. Marketing services (SEO/ads) are optional but recommended for growth.

How long does a professional services website take to build?

Typical timelines are 6–10 weeks depending on size, content, and integrations.

Should I choose a DIY builder (Wix/Squarespace) or an agency?

DIY is cheapest but limited for SEO and enquiries. Agencies or specialist systems cost more upfront but deliver measurable ROI.

What are the hidden costs to watch for?

Content, SEO migration, site speed, accessibility, and ownership of your assets are the common “gotchas.”

What ongoing budget should I plan for marketing?

If growth is the goal, expect £1,000–£3,000/month across SEO, content, or ads — on top of the build.

How do I measure ROI from my website?

Use analytics + CRM to track leads, consultations, and matters opened. The ROI lens is: enquiries in vs. margin gained.
