To choose the right web design agency, start with what the website has to achieve, then shortlist agencies whose past work shows they’ve solved similar problems. Ask each one how they’d approach your project, who would do the work, what’s included in the price and what happens after launch. The right agency asks more about your business than about colours, explains its process plainly and gives you a quote you can compare line by line. The wrong one is usually keen to start designing before it understands what you sell.
Most of the decision comes down to the questions you ask in the first two meetings. Here’s how to run that process.
Start with what the website needs to do
Before you speak to anyone, write down what the new site must achieve, in plain terms. “More enquiries from mid-sized firms.” “Let customers book appointments online.” “Stop the team spending an hour a day answering the same questions.” This is the brief that every agency should respond to, and it’s the yardstick for judging their answers.
To make this concrete, picture a hypothetical business we’ll follow through the guide. Say you run a 20-person accountancy practice in Richmond. Your current site is eight years old, hard to update, and brings in almost no enquiries. You want a site that wins more business clients, explains your services clearly and lets clients upload documents securely.
Add a rough budget range and a deadline if there is one (a new financial year, a rebrand launch). Agencies can only give you sensible advice if they know the constraints.
What does a web designer actually do?
A web designer plans how a website looks and works: page structure, layout, navigation, typography, colour and the way people move from arriving to getting in touch. A web developer builds it, turning the designs into working code and connecting it to other systems. In an agency, you’ll usually also have a project manager, a UX specialist and sometimes a copywriter and SEO specialist.
That matters when you’re comparing options. The accountancy practice needs design, development, a secure document upload integration and probably help with content. A single freelancer may be excellent at one or two of those. An agency covers them all under one contract.
Agency or freelancer: which is better for a business website?
A freelancer is often the better choice for a small, simple site: a few pages, a contact form and a modest budget. You deal directly with the person doing the work, and overheads are lower.
An agency makes more sense when the site is complex or important to sales, because design, development, content and support need different skills that one person rarely has. You also get continuity: if someone is ill or leaves, the project carries on. For our accountancy practice, with integrations and client data involved, an agency is the safer bet.
Some businesses do well with a mix: an agency for the build and a freelancer they trust for small updates afterwards. Whichever you choose, the questions below still apply.
How do I choose the right web design agency?
Shortlist three or four agencies, then compare them on evidence: past work, references and how they handle your questions.
- Look at their portfolio, then look closer. Find projects similar in size and complexity to yours. Visit the live sites, try them on your phone, and check they still load quickly.
- Read their own website critically. It doesn’t need to match your style, but it should be fast, clear and easy to use. An agency whose own site is slow and confusing is telling you something.
- Ask for references and call one. A past client will tell you how the agency handled delays, changes and problems after launch, which no case study covers.
- Notice how they handle the first call. Do they ask about your customers, your competitors and your sales process? Or do they jump to templates and colour palettes?
- Check what they do after launch. Hosting, maintenance, security updates and ongoing improvements all matter. A website that’s left alone after launch slowly decays.
The best sign of a good agency is the quality of the questions it asks before it quotes.
What questions should I ask a web designer before hiring?
Take this list into each meeting. The answers will make the differences between agencies obvious quickly.
- Who will work on our project day to day? Ask to meet the designer or project lead, as well as the person selling.
- What’s your process? A sound process includes discovery (often a workshop), wireframes approved before visual design, design approval before build, testing, and a planned launch.
- What’s included in the quote, and what isn’t? Content writing, photography, SEO set-up, accessibility testing, training and hosting are often extras.
- Who will own the website, the domain and the hosting account? You should. Make sure you’ll have full admin access and can move the site if you ever change supplier.
- What platform will you build on, and why? WordPress is widely used and easy to edit; a proprietary system may lock you in.
- How do you handle accessibility? A good answer mentions the WCAG 2.2 AA standard and how they test against it.
- How will you protect our search rankings? If you’re replacing an existing site, they should plan redirects from every old page address that has traffic or links.
- What happens after launch? Ask about support response times, security updates and the monthly cost.
What are the signs of a good web development company?
Good web development companies are usually easy to spot once you know what to look for:
- A portfolio of live, working sites, with some clients who’ve stayed for years.
- Clients you can speak to. Agencies with happy clients are glad to put you in touch.
- Clear, prompt communication: a named contact, regular updates and straight answers when something slips.
- Ongoing maintenance and support, so updates, security and fixes have an owner after launch.
- An understanding of the wider picture. They don’t have to run your SEO or ads themselves, but they should build a site that works with them: fast, well structured and properly tracked.
And the warning signs to walk away from:
- A guarantee of first-page Google rankings. Nobody controls Google’s results.
- A quote produced before anyone has asked about your business.
- Reluctance to give you admin access or put the domain in your name.
- A price far below everyone else’s with a vague scope. The missing work tends to reappear later as extras.
How much does a website cost in the UK?
Website costs in the UK vary widely because scope varies widely. As a rough guide, a small template-based site from a freelancer might cost a few hundred to a couple of thousand pounds. A custom business website from an agency typically runs into five figures. E-commerce, client portals and integrations with other systems add to that.
The accountancy practice, with a custom design, around 20 pages, secure document upload and help with content, would sit in the agency range. The useful question is what each quote includes. Ask agencies to break their price into discovery, design, development, content, testing and launch, and budget separately for hosting and maintenance afterwards. Two quotes that look far apart often turn out to cover very different amounts of work.
How we work with clients
We’ve been designing and building websites for 25 years, with more than 250 projects behind us, and the work is done by our in-house team, based in Twickenham, West London. Every project starts with a discovery workshop and approved wireframes before any visual design, and we host and look after more than 100 WordPress sites after launch through our care plans. If you’re comparing agencies, you can see how we approach web design in London, and our website redesign checklist is a useful companion to this guide.
FAQs
What should I look for in a web design portfolio?
Look for live sites similar to yours in size and complexity, and test them yourself on a phone: how fast they load, how easy they are to navigate and whether forms work. A varied portfolio across different sectors suggests an agency that designs around each client rather than reusing one style.
How long does it take to build a business website?
A custom business website typically takes two to four months from the first workshop to launch. Smaller sites can be quicker, while e-commerce sites and projects with integrations take longer. Delays most often come from content and feedback, so agree who supplies what, and by when, at the start.
Should I own my website and domain if an agency builds it?
Yes. The domain should be registered in your business’s name, and you should have full admin access to the website and hosting. That way you can change supplier without losing your site, your email or your search history.
Do web design agencies also handle SEO?
Many do, and at minimum a good agency builds the technical foundations: fast pages, clean structure, proper headings, metadata and redirects from your old site. Ongoing SEO, such as content and link building, is usually a separate service, so check whether it’s included in the quote or offered as an add-on.
