We decided to create an Online shop for selling medicines. So we started with negotiations of the concept and the collection of the requirements.

After approving everything they start creating a solution.I think that we're about 10-12 people in the team who worked with us. We launched shop and receiving profit from it, I think that's the best outcome.

Reviews verified by DesignRush and sourced from the agency's profile View All Reviews
What certifications should a United Kingdom website development agency have?
A United Kingdom website development agency should have certifications related to legal compliance and information security to demonstrate professionalism and adherence to best practices.
Key credentials include:
ISO 27001 for information security
ISO 9001 for quality management
Cyber Essentials or Cyber Essentials Plus for UK-specific cybersecurity assurance
It’s also helpful if the team holds platform-specific or developer certifications, such as AWS, Azure, GoogleCloud, Adobe, or recognized frontend/backend development credentials. Membership in professional bodies like BCS (The Chartered Institute for IT) further signals credibility and adherence to industry best practices.
How long does a typical web development project take?
A typical web development project takes 6-12 weeks, depending on the site’s size, features, and design complexity. Simple brochure-style websites may be completed in 3-6 weeks, while more advanced sites with custom functionality or integrations take longer.
Content readiness, feedback speed, and revision cycles also affect the timelines. eCommerce platforms or custom web applications can extend to 3-6 months or more due to testing, optimization, and deployment requirements.
What happens after a website development project finishes?
After a website development project finishes, the agency typically conducts final testing, qualityassurance, and launchsupport to make sure the site works smoothly across all devices and browsers. They also hand over credentials, documentation, and training so your team can manage the site confidently.
Most companies offer ongoingmaintenance, securityupdates, backups, and performancemonitoring to keep the website stable and up to date. You can also choose optional services like content updates, feature enhancements, and SEO support to continue improving your site after launch.
Do web development companies in the United Kingdom offer fixed-price packages?
Yes, many UK web development companies offer fixed-price packages. When you consider a fixed-price package, make sure:
The scope and deliverables are clearly defined upfront
Payment terms, revisions, and any additional costs are transparent
There’s clarity on what happens if the project scope changes or grows
Can web development agencies in the United Kingdom work within tight deadlines?
Yes, many web development agencies in the United Kingdom can work within tight deadlines, especially when dealing with well-defined projects or smaller websites. They often streamline timelines by allocating extra resources, using proven frameworks, and following efficient project management processes.
The ability to meet a fast turnaround depends on project complexity, content readiness, and how quickly you provide feedback. For urgent projects, agencies may offer expedited services at a higher rate to ensure quality isn’t compromised.
