How to choose a web design agency: 10 questions to ask before you sign

Choosing a web design agency is one of those decisions where the cost of getting it wrong is high and mostly hidden. A bad build doesn't announce itself on launch day — it shows up months later as a site nobody can find on Google, a login you don't have, or a bill for changes you assumed were included. The good news is that almost all of that is avoidable if you ask the right questions before any money changes hands. This is the list we'd want a friend to use, even if it meant they picked someone other than us.

Start with who actually does the work

The oldest trick in the agency book is to pitch with the senior team and then hand the build to whoever's cheapest. So ask, plainly: who will design my site, who will build it, and who is my point of contact when something breaks? You want a named person, ideally one you speak to before you sign. There's nothing wrong with junior staff doing parts of the work — everyone starts somewhere — but there's a lot wrong with being sold one team and given another.

It's also worth asking whether design and development happen under one roof. Plenty of agencies design a beautiful mockup and then outsource the actual web development to a third party, which is where quality and accountability tend to leak away. When the people who draw it also build it, far fewer things get lost in translation.

Ask whether you'll actually own it

This is the question that saves people the most pain, and almost nobody thinks to ask it. If an agency builds your site, will you own it? Get explicit, written answers on four things:

• The domain name is registered in your name and account, not theirs. This one catches out more small businesses than any other.
• The hosting account is yours, or at minimum can be handed to you without a fight.
• The CMS and admin logins belong to you, so you're never locked out of your own website.
• The site files or code are yours to take elsewhere if the relationship ends.

Be especially careful with agencies that build on a proprietary platform you can only rent from them forever. It can be a perfectly good arrangement — but you should choose it knowingly, not discover it the day you try to leave. A site you don't control is a site someone else can hold hostage.

Push past the pretty portfolio

Every agency has a portfolio full of good-looking work; that's the easy part. The useful questions are underneath it. Are any of these sites in a sector like mine, or serving a similar kind of customer? What a fashion brand needs is not what a solicitor or a wholesaler needs. Can I visit the sites live, on my own phone, rather than looking at polished screenshots? A live site tells you about speed and behaviour that a mockup will always flatter.

Then ask the question that separates decorators from builders: what did this site actually do for the client? More enquiries, more sales, better rankings — or just a nice new look? A site that isn't tied to a business outcome is a brochure, and you can tell a lot about an agency by whether they think in terms of outcomes or only in terms of aesthetics. If you want to see what "outcome-led" looks like in practice, our own web design work starts from what the site needs to earn, not just how it should look.

Find out how it's built under the surface

You don't need to become a developer, but a couple of technical questions will tell you whether an agency builds for the long term or just for the demo. The most important one: is the content of my pages present in the HTML the server sends, or does it only appear once JavaScript runs? This sounds obscure, but it's the difference between a site Google can read easily and one it might quietly skip. It's the single most common reason a fresh, expensive site never shows up in search — we've written about exactly why sites stay invisible on Google if you want the detail.

Ask about speed, too. What load times do their recent builds hit on a mobile connection, and how do they keep sites fast as content and features pile up? A slow site loses visitors and rankings at the same time, and speed is far easier to build in from the start than to bolt on later.

Nail down SEO, timelines and what "done" means

Three practical things trip up more projects than any design disagreement. First, SEO. A good build includes the fundamentals as standard — clean structure, sensible page titles, a sitemap, fast performance. If an agency treats basic search-friendliness as a costly extra, take note. And if anyone guarantees you first-page rankings, walk away: no honest agency can promise that, because none of us control Google's results.

Second, timelines. Ask for a realistic schedule with milestones — and ask what they need from you, and when. Projects slip far more often because client content and feedback arrive late than because the agency is slow. A small brochure site is usually two to six weeks; a larger custom or e-commerce build is often two to four months. Anyone promising a complete site in a few days is selling you a template.

Third, what happens after launch. A website is not a painting you hang and forget; it needs updates, security patches and the odd fix. Ask what's covered once the site goes live, what a change costs, and whether there's an ongoing care arrangement. Clarity here prevents the awkward invoice six weeks in for something you assumed was included.

The best question you can ask any agency is a simple one: "What would you tell me not to spend money on?" The honest ones always have an answer.

Trust the ones who tell you the truth

If you take one thing from this list, make it this: the questions worth asking are rarely about design. They're about ownership, honesty and what happens when things go wrong — and the way an agency answers them tells you far more than any portfolio. Someone who talks you out of a feature you don't need, quotes a realistic timeline, and refuses to promise rankings they can't deliver is worth more than someone who agrees to everything and disappears after launch.

Budget matters too, of course, and it's worth going in with a rough sense of the market so you can tell a fair quote from a fanciful one — our honest guide to what a website costs in the UK lays out the real ranges. Beyond that, pick the people who answer straight questions with straight answers.

If you'd like to put these questions to us, we'll answer every one of them plainly — including the ones about what we'd tell you not to bother with. Tell us about your project and we'll give you an honest read on it.
