Frequently Asked Questions

How is a web development agency different from hiring a freelance developer?

A website development agency offers a full team of specialists — including front-end and back-end developers, designers, QA testers, and project managers — to deliver robust, scalable websites. Freelancers may have limited capacity and expertise, making agencies a better fit for complex or enterprise-level projects.

What services does a website development agency offer?

A web development agency designs, builds, and maintains websites and web applications, including front-end design, back-end development, system integrations, CMS implementation, and ongoing performance optimisation — delivering end-to-end digital solutions tailored to your business goals.

How much does website development cost?

The cost varies based on project size, complexity, and required features. Custom web applications or enterprise platforms will cost more than templated websites. At Box UK we provide tailored quotes based on your business goals and technical requirements, ensuring you get the right solution for your budget

How long does it take to build a website?

Website development timelines can range from a few weeks for smaller CMS sites to several months for custom applications or enterprise platforms. Factors affecting duration include scope, integrations, and design complexity. We follow an Agile delivery model to ensure speed, transparency, and flexibility throughout

What CMS platforms do web development agencies use?

The most widely used CMS platforms include WordPress, Drupal, and similar enterprise-grade systems. At Box UK we specialise in WordPress (including WordPress VIP) and Drupal, helping you choose the right platform based on your content needs, workflows, and integration requirements.

How secure are custom web development solutions?

Security should be built in from the start, not bolted on after launch. Best practices include advanced encryption, secure authentication, regular code reviews, and adherence to standards such as ISO 27001 and Cyber Essentials accreditation — all of which Box UK holds as standard.

Can you integrate a website with other business systems?

Yes. Modern websites can be integrated with CRMs, ERPs, analytics platforms, payment gateways, and marketing tools to ensure seamless data flow across your digital ecosystem. Box UK handles third-party integrations as part of our full-service development offering.

What should I look for in a web development partner?

Look for proven experience across complex projects, robust security credentials, modern technology practices, and strong client references. Key indicators include ISO certification, Agile delivery capability, and a track record of measurable results across your sector.
