How to Choose a Web Design Agency for Your Service Business

Before You Start

Before contacting agencies, know:

Your budget: £2,000–8,000 for a good custom site, or £300–800/year for a template.
Your goal: More enquiries? Phone calls? Bookings? A vague goal leads to a vague website.
Your timeline: 4–8 weeks is typical for a custom site. Agencies taking 12 weeks are slow. Agencies promising 2 weeks are rushing.

Questions to Ask

1. Do You Have Experience with Service Businesses?

Plumbing isn't the same as consulting, which isn't the same as real estate. Agencies that specialise in service businesses understand:

The importance of a visible phone number.
Local SEO and service area pages.
Lead conversion funnels (visitor → phone call → job).

Ask for examples of 3–5 service businesses they've built sites for.

Red flag: They've only built sites for restaurants, e-commerce, or creative agencies. Service business websites have different needs.

2. What's Your Process?

A good process looks like this:

Discovery (1–2 weeks): Learn about your business, competitors, and goals.
Strategy (1 week): Present a plan. Homepage layout, service pages, technical approach.
Design (2–3 weeks): Show visual mockups. Revise based on your feedback.
Development (2–4 weeks): Build the site in code.
Testing and launch (1 week): QA, content review, go live.
Handover (2–3 hours): Train you on how to update the site.

Red flag: No discovery phase. If they start designing without learning about your business, it won't work.

Red flag: No strategy phase. You should see a plan before they start building.

3. Can You Show Examples?

Ask for 5–10 live websites they've built. Visit them on mobile and desktop. Ask:

Do they load fast? Use PageSpeed Insights on their examples. Agencies that build slow sites will build you a slow site.
Are they converting? Do they have a clear phone number? CTA buttons? Service descriptions?
Are they mobile-friendly? Tap the buttons. Can you fill a form on mobile? Is text readable?
Do they have trust signals? Reviews, testimonials, photos of work?

If their examples don't convert, they won't build you a converting site.

Red flag: Vague examples ("I built this but the client took it down"). Ask for live examples you can verify.

4. What Do You Charge, and What's Included?

A good agency will itemise:

Design hours and cost.
Development hours and cost.
Hosting and maintenance included or separate?
Content writing or does the client provide it?
SEO setup (schema, metadata, sitemap)?
How many revisions are included?
What happens after launch (support, training, bug fixes)?

Red flag: A flat quote with no breakdown. This usually means they've underestimated or are hiding surprises.

Red flag: "We'll charge you for revisions." Revisions are normal. 2–3 rounds should be included. More than that, the client isn't being clear on requirements.

5. Who Owns the Code and Content?

You should own the code and content. If you leave the agency, you should be able to move your site to another host or developer.

Red flag: "You'll need to pay us to access your site" or "You can only edit through our custom dashboard." You're being locked in.

Good: "The code is yours. You can move it anywhere. Here's the Git repository."

6. What's Your SEO Process?

A good agency will include:

Schema markup (local business, breadcrumbs, article markup for blog).
Optimised titles and meta descriptions.
Site speed optimisation.
Mobile-friendly testing.
Sitemaps and robots.txt.
Keyword research for main pages.

Red flag: "We'll do SEO after launch for an extra £2,000/month." Basic on-page SEO should be part of the build.

Red flag: "We guarantee rankings." No one can. They can promise technical SEO work, but not rankings.

7. What's the Hosting and Maintenance Plan?

After launch, someone needs to manage:

Security updates and patches.
Backups.
Plugin or framework updates.
Monitoring for issues.

Ask:

Do you include hosting, or do I hire my own host?
What's the monthly maintenance cost?
How quickly do you respond to urgent issues?
Am I locked into hosting with you, or can I move?

Red flag: "You're on your own after launch." Every site needs maintenance.

Red flag: Expensive monthly costs with vague services. "Monthly support: £300" with no detail on what that includes.

8. Can You Give Me References?

Ask for 3 past clients you can call (not email). Ask them:

Was the project on time and on budget?
Is the site still performing well?
Are there issues since launch?
Would you hire them again?

Red flag: Unwillingness to provide references, or references who won't answer questions.

Red Flags to Watch

No discovery process: They start designing before understanding your business.
Too cheap: £500 for a custom website is a template with minimal work.
Too fast: Promising a complete site in 2 weeks means they're rushing or recycling templates.
No examples: Can't show live work.
Overpromising: Guaranteed rankings, guaranteed leads, "we've never had a failed project."
No process: They can't explain how they work or what phases are involved.
Vague pricing: No breakdown of what you're paying for.
You don't own the code: You're locked into them for future changes.
No post-launch plan: They disappear after launch.

Red Flags During the Project

Slow communication: Emails taking days to answer.
Scope creep: New features keep being added, pushing the deadline.
No progress: Weeks pass and you haven't seen mockups or a progress update.
They ignore your feedback: You ask for changes and they ignore them or say "we know better."

The Interview

Schedule a 30-minute call with 2–3 agencies. Ask:

"Walk me through your process from start to finish."
"What do you need from me to succeed?"
"Can you show me examples of service business sites you've built?"
"What's the total cost and what's included?"
"What happens 6 months after launch?"

By the end of these calls, you should feel:

Confident they understand service businesses.
Clear on what they'll build and how much it costs.
Comfortable they'll support you after launch.
Like they've asked good questions about your goals.

If you don't feel this way, keep looking.

The Decision

Choose the agency that:

Has experience with service businesses and can prove it.
Has a clear process and can explain it.
Charges fairly and includes what you need.
You trust to be responsive and supportive.

Not necessarily the cheapest or the biggest name.
