How to Choose a Web Design Agency UK — 12 Things to Check Before You Hire

Choosing a web design agency feels like choosing a builder. Everyone says they are the best. The quotes range from £300 to £30,000 for what sounds like the same job. Half the portfolio sites look the same. And you have no idea whether the finished product will actually bring in customers or just sit there looking pretty.

We are a web design agency, so yes, we have skin in this game. But we would rather you hire the right agency — even if it is not us — than waste thousands on the wrong one. A bad agency costs you far more than their fee. It costs you months of lost business while your website underperforms.

This guide gives you twelve things to check before you hire any web design agency in the UK. Use it as a checklist. If an agency ticks every box, they are probably worth your money. If they fail on several, keep looking.

1. Check Their Own Website First

This sounds obvious but you would be amazed how many web design agencies have terrible websites. If they cannot build a good website for themselves, what are they going to build for you?

Look at their site on your phone. Is it fast? Is it easy to navigate? Does it look professional? Is the content well-written or full of generic waffle about “leveraging synergies” and “holistic digital solutions”?

Check whether their site ranks on Google. Search “web design [their location]” and see if they appear. An agency that cannot rank their own website for their own service in their own area is not going to rank yours.

Look at the basics. Is there an SSL certificate (the padlock icon in the browser)? Does it load quickly? Are the images sharp and properly sized? If they cut corners on their own site, they will cut corners on yours.

2. Look at Real Portfolio Work

Every agency has a portfolio page. But look carefully. Some agencies show template mockups, not real client websites. Others show work from five years ago that no longer represents their current quality.

Click through to the actual live websites in their portfolio. Visit them. Test them on your phone. Check if they load quickly. See if they rank on Google for anything relevant.

Ask yourself: do these websites look like they generate business for their owners? A beautiful design that nobody can find on Google is not a successful project. A well-designed site that ranks on page one and has clear calls to action — that is what you want.

If the portfolio only shows one type of business, consider whether they understand your industry. An agency that builds exclusively for restaurants may not understand what a construction company needs from a website.

3. Ask About SEO Before Anything Else

This is the question that separates good agencies from bad ones. Ask: “Is SEO included in the build, or is it extra?”

Many agencies build a website, hand it over, and then offer SEO as a separate monthly service costing £500 to £2,000 on top. That means you have paid for a website that is invisible on Google by design — so that you pay them again to fix it.

A good agency builds SEO into the website from day one. That means proper title tags, meta descriptions, heading hierarchy, schema markup, fast loading speeds, mobile responsiveness, keyword-optimised content, internal linking, and an XML sitemap. These are not extras. They are fundamental to a website that works.

Ask specifically what SEO elements are included. If the answer is vague — “we make it SEO-friendly” — push for details. If they cannot list specific technical SEO actions, they are not doing real SEO.

At iFox Masters, basic SEO is included in every package because we believe a website without SEO is a waste of money. We do not build invisible websites and then charge you monthly to make them visible.

4. Demand Transparent Pricing

“Contact us for a quote” is the web design industry’s version of “market price” on a restaurant menu. It usually means the price depends on how much they think you can afford.

A good agency publishes their pricing or at least gives clear starting points. They can tell you exactly what is included in each package and what costs extra. There should be no surprises on the invoice.

Before you commit, get clarity on these costs:

• The build cost — the one-off fee to design and develop the website.
• Hosting — is it included? For how long? What is the monthly cost after that?
• Domain — do you own it, or does the agency own it on your behalf?
• SSL certificate — should be free and included. If they charge for this, walk away.
• Content — is copywriting included or do you supply all text and images?
• Revisions — how many rounds of changes are included before extra charges apply?
• Maintenance — what happens after launch? What does a monthly support plan cost?
• SEO — included or separate? If separate, how much per month?

Add all of these up and compare the total first-year cost, not just the headline build price. A £500 website that costs £200 per month in extras is actually a £2,900 website in year one.

5. Find Out Who Owns the Website

This is the question that catches out more business owners than any other. When the website is finished, who owns it?

Some agencies build your website on their own hosting and their own domain account. If you leave them, your website stays with them. You are effectively renting your website, not buying it.

Some agencies use proprietary platforms. Your website is built on their system and cannot be moved. If you want to change agencies, you start from scratch.

The right answer is: you own everything. Your domain is registered in your name. Your hosting account is in your name or transferable. Your website files are yours to take if you choose to leave. You should be able to walk away from any agency and take your website with you.

Ask this question directly before you sign anything. Get the answer in writing.

6. Read Google Reviews, Not Testimonials

Testimonials on an agency’s own website are cherry-picked. They choose the best ones and discard the rest. Some agencies even write their own testimonials. You would never know.

Google reviews are different. Anyone can leave one. They cannot be deleted by the business. And the patterns they reveal are far more telling than a curated testimonial page.

Look for consistent themes in the reviews. Do clients mention good communication? Do they mention meeting deadlines? Do they mention ongoing support after launch? These are the things that matter.

Pay attention to negative reviews too. Every business gets the occasional bad review. What matters is how the agency responds. A professional, empathetic response that addresses the issue shows maturity. A defensive or dismissive response tells you everything about how they handle problems.

Check Trustpilot, Facebook reviews, and Clutch as well. The more sources you check, the clearer the picture becomes.

7. Ask How They Handle Communication

Bad communication is the number one complaint about web design agencies. Projects drag on for months because emails go unanswered, feedback takes weeks to implement, and you never know what is happening with your project.

Before you hire, ask:

• Who is your main point of contact? Will you deal with one person or be passed between departments?
• How do they communicate? Email, phone, Slack, project management tool? What is their typical response time?
• How often will you receive updates? Weekly? Fortnightly? Only when you chase them?
• What is the process for requesting changes? How long does a revision take?

The best agencies set clear expectations upfront. They tell you the project timeline, the milestones, and exactly when you need to provide feedback. They do not disappear for three weeks and reappear with something you did not ask for.

8. Check Their Technical Skills

Web design is not just about making things look nice. A good agency needs technical skills across design, development, and SEO. Here is how to assess them.

Ask what technologies they use. Modern websites should be built with clean HTML5, CSS3, and minimal JavaScript. If they are building everything in Flash (yes, some still try), run away. If they are building on outdated platforms, question why.

Ask about mobile responsiveness. The answer should not be “yes, it works on mobile.” It should be “we design mobile-first and optimise for all screen sizes.” Over 60 percent of web traffic comes from mobile devices. Your website must work flawlessly on phones and tablets.

Ask about page speed. Can they tell you what Core Web Vitals are? Do they optimise images, minify code, and implement lazy loading? A slow website loses visitors and ranks poorly on Google.

Ask about accessibility. A good agency ensures websites are accessible to people with disabilities — proper colour contrast, alt text on images, keyboard navigation, screen reader compatibility. This is not just good practice, it is becoming a legal requirement.

Ask about security. SSL certificates, regular updates, secure hosting, backup procedures. Your website handles customer data through contact forms at minimum. It needs to be secure.

9. Understand Their Design Process

Every good agency has a defined process. If they cannot explain their process clearly, they do not have one — and your project will suffer.

A typical process looks like this:

1. Discovery — the agency learns about your business, your customers, your goals, and your competitors.
2. Strategy — they define the site structure, identify target keywords, plan the content, and create a sitemap.
3. Design — they create mockups or wireframes showing what the website will look like.
4. Development — they build the website based on the approved designs.
5. Content — text, images, and media are added to the site.
6. Testing — the site is tested across devices and browsers for bugs, broken links, and speed issues.
7. Launch — the site goes live. The agency handles the technical deployment.
8. Post-launch — ongoing support, monitoring, and maintenance begins.

If an agency skips the discovery and strategy phases and jumps straight to design, they are building something based on assumptions rather than understanding. The result is a website that looks fine but does not perform.

10. Ask What Happens After Launch

This is where many agencies drop the ball. They build a beautiful website, hand it over, and disappear. Six months later, the site has broken links, outdated content, security vulnerabilities, and no ongoing SEO.

Ask these questions:

• Do they offer ongoing maintenance? What does it include and what does it cost?
• Who handles hosting and updates? Is the site on managed hosting with automatic updates, or are you responsible?
• What is the support process for issues after launch? Is there a helpdesk, an email address, a phone number?
• Do they offer ongoing SEO? Will they continue building links, creating content, and monitoring rankings?
• Is there a minimum contract period? Some agencies lock you into 12 or 24 month contracts.

A website is not a one-time project. It needs ongoing attention to stay secure, fast, and visible on Google. Make sure your agency provides this or that you have a plan to handle it yourself.

11. Compare Like for Like

When you have quotes from multiple agencies, make sure you are comparing like for like. A £500 quote and a £5,000 quote might seem like the same job, but they almost certainly are not.

The £500 quote might be a template with your logo swapped in, no SEO, no content creation, no ongoing support, and hosting that costs £30 per month on top.

The £5,000 quote might include custom design, professional copywriting, full SEO, twelve months of hosting and maintenance, and a monthly performance report.

Create a simple spreadsheet. List every feature and service across the top. List each agency down the side. Fill in what is included and what costs extra. Compare the total first-year cost and the ongoing annual cost.

The cheapest build price is rarely the cheapest total cost.

12. Trust Your Gut

After all the research and due diligence, there is one final test. Do you like talking to these people?

You are going to work closely with this agency for weeks or months. You will share your business goals, your challenges, and your budget with them. If the initial conversations feel uncomfortable, pushy, or dismissive, the project will be worse.

A good agency listens more than it talks in the first conversation. They ask questions about your business before they start pitching solutions. They are honest about what they can and cannot do. They do not promise page one rankings in a week or guarantee specific results.

If it feels right, it probably is. If something feels off, trust that instinct and keep looking.

The Red Flags — Walk Away If You See These

To save you time, here are the signs of an agency you should avoid:

• No published pricing and reluctance to discuss costs early in the conversation.
• A portfolio full of template sites that all look the same.
• They own your domain and hosting, not you.
• SEO is always a separate upsell, never included.
• No Google reviews, or only reviews from years ago.
• They guarantee specific rankings — nobody can guarantee Google rankings.
• They cannot explain their process clearly.
• Communication is slow or vague during the sales process — it only gets worse after you pay.
• They push a long-term contract before you have seen any work.
• Their own website is slow, ugly, or does not rank for anything.
• They use jargon to confuse you rather than plain language to inform you.
• They talk about themselves more than they ask about you.

If an agency shows three or more of these red flags, keep looking. The right agency is out there.
