FAQ

What should I expect to pay for a professional website from a UK agency?

Professional website costs in the UK typically range from £3,000 for basic business sites to £50,000+ for complex e-commerce or custom applications. The investment depends on functionality requirements, design complexity, and ongoing support needs. Focus on value rather than just price—a well-built website can generate significant ROI through improved lead generation and customer conversion.

How long does it typically take to complete a website project?

Most professional website projects take 8-16 weeks from initial brief to launch. This includes discovery, design, development, testing, and content creation phases. Complex projects with custom functionality or extensive content requirements may take 20+ weeks. Clear project scoping and communication can help ensure timely delivery.

What ongoing support should I expect from my web development agency?

Professional agencies should provide hosting management, security updates, backup services, and technical support. Many offer monthly retainer packages that include content updates, performance monitoring, and SEO optimisation. Clarify support terms before signing contracts to avoid unexpected costs.

How important is it to choose an agency that understands my industry?

Industry expertise is crucial, particularly for specialised sectors like construction and property. Agencies familiar with your industry understand regulatory requirements, customer behaviour, and effective marketing strategies. This knowledge translates into more effective websites that generate better business results.

What's the difference between template-based and custom website development?

Template-based websites use pre-designed frameworks that are customised with your content and branding. They're faster and cheaper but may have functionality limitations. Custom development creates unique solutions tailored specifically to your requirements but requires more time and investment. The choice depends on your specific needs and budget.

How can I measure the success of my new website?

Key metrics include organic traffic growth, conversion rates, lead generation, user engagement (time on site, pages per session), and search engine rankings. Professional agencies should provide regular reporting and analytics insights to demonstrate ROI and identify optimisation opportunities.

What should I look for in an agency's portfolio?

Examine projects similar to your requirements, focusing on functionality rather than just visual appeal. Look for case studies that demonstrate measurable results, client testimonials, and evidence of long-term client relationships. Pay attention to mobile responsiveness and loading speeds of their previous work.
