How to Choose a Web Design Agency in Cardiff: 10 Questions to Ask

Cardiff's digital scene has grown significantly over the past decade. From Roath to the Bay, there are now dozens of agencies claiming to build great websites. Some are brilliant. Some will take your money and hand you a generic WordPress theme with a stock photo of a handshake.

Choosing the right web design agency in Cardiff isn't about finding the cheapest quote or the flashiest portfolio. It's about finding a team that understands your business, communicates clearly, and delivers something that actually works — not just looks pretty.

Here are the ten questions you should ask any agency before committing.

---

1. Can You Show Me Recent Work for Cardiff or Welsh Businesses?

Local knowledge matters. An agency that has worked with Cardiff businesses — whether that's a Pontcanna café, a Bay-based professional services firm, or a Canton retailer — will understand your market, your customers, and the local competitive landscape far better than a generic national agency.

Ask to see relevant case studies. Not just screenshots, but actual results: traffic growth, conversion rates, client testimonials. Any reputable agency will have these ready.

2. Who Will Actually Be Working on My Project?

Many agencies win work with senior directors in meetings, then hand it off to junior staff you've never met. Ask directly: who will be your day-to-day contact? Who is doing the design? Who builds the site?

Smaller Cardiff agencies often offer more direct access to the people doing the work, which means faster communication and fewer misunderstandings. Larger agencies bring deeper teams but can be slower to respond. Know what you're getting.

3. What's Your Process from Brief to Launch?

A good agency has a clear, repeatable process. Expect to hear about discovery (understanding your business goals), wireframing or prototyping, design approval stages, development, content review, testing, and launch. Red flags include agencies that jump straight to design without asking questions, or those who can't articulate their process at all.

Ask for a typical project timeline. For a standard small business website, 6–10 weeks is reasonable. If they promise it in two weeks for a complex site, be cautious.

---

4. Will My Website Be Mobile-First?

Over 60% of web traffic in the UK now comes from mobile devices. "Mobile-friendly" is no longer enough — you need a site designed for mobile first, then scaled up to desktop.

Ask to see examples of their mobile designs. Pull them up on your phone during the meeting. If the mobile experience is an afterthought, walk away.

---

5. What Platform Will You Build On, and Will I Own It?

This is a big one. Some agencies build on proprietary platforms that lock you in — meaning you can't take your site elsewhere without rebuilding from scratch. Others build on open platforms like WordPress, Webflow, or Next.js where you retain full control.

Ask specifically: who owns the website code and the domain? You should. Ask what happens if you part ways — can you take the website with you? Get this in writing.

---

6. What Does SEO Look Like in Your Build Process?

A beautiful website that nobody finds is useless. Ask how the agency approaches search engine optimisation as part of their build process. Good agencies bake SEO in from the start: proper heading structures, fast page speeds, clean URLs, schema markup, and localised metadata.

If "we can add SEO later as an extra" is the answer, that's a bad sign. Basic technical SEO should be standard.

---

7. What Are Your Ongoing Support and Maintenance Options?

Websites aren't set-and-forget. Security patches, plugin updates, content changes, new pages — all of these need handling. Ask what happens after launch. Do they offer a monthly support retainer? What's the cost? What's the response time for urgent fixes?

Plenty of Cardiff businesses have been stung by agencies who disappear after launch. Make sure there's a clear support structure — even if it's just a defined hourly rate for ad-hoc changes.

---

8. Can You Provide Hosting, or Is It Separate?

Some agencies bundle hosting with their service; others leave it to you. Both approaches are fine, but you need to know what you're paying for. If they handle hosting, ask: where are the servers located? What uptime do they guarantee? What does backup look like?

For local Welsh businesses, UK-based hosting is generally preferred for data compliance and performance.

---

9. How Do You Measure Success?

A professional agency should be able to define success before the project starts. That means agreeing on goals upfront: is it organic traffic? Lead form submissions? E-commerce revenue? Time on site?

Ask how they'll track and report on these metrics. Will you get access to Google Analytics or an equivalent? Will they provide a post-launch performance review at 30 or 90 days?

---

10. What's the Total Cost — and What's Not Included?

Web design quotes can be notoriously opaque. Ask for a full cost breakdown and specifically ask what's not included. Common extras that can inflate bills include: copywriting, photography, SEO setup, email setup, CMS training, and stock imagery.

Get everything in writing. A fixed-price contract is generally safer than an open-ended hourly engagement, especially if you're on a tight budget.
