Mobile App Development Review from Abdelrahman ALMULLA
wdi took the vision we had and turned it into something even better. They built this incredibly detailed app that lets users filter hotels based on things like airport transfers, car services, or other specific amenities. Travelers can also quickly spot deals or limited-time offers with just a glance.
One of the coolest parts is how the app keeps guests updated when theyre checked into a hotel - whether it's on-site events or nearby activities, theyll get notifications straight to their phone. The feedback system they added is a game-changer. Guests can send questions or share thoughts right from their rooms, and they get notified the moment theres a response.

We had many very clear outcomes and timelines based on our needs that were identified before the project began. They provided regular updates and progress reports via email and virtual meetings throughout the project. Typically in two-week sprints.

Choosing dotcode was one of the best decisions we made for our business. Their team's ability to understand our vision and turn it into reality was remarkable. Not only did they provide app development, but they also ensured our project was completed quickly and successfully.

Product Design Review from Sofia Diaz
I had an idea and vision, which intent helped me bring to life. We required a platform that would be usable on different types of mobile and desktop devices, as well as work on different browsers.
We went through the process of designing the product and building an MVP. Their UX designer evaluated the mockups I gave them. Then, they gave me some suggestions on how to improve the product and provided a UI designer, who built the interfaces.
From there, intent handled the following stages of product development. We went through several iterations based on user feedback for the MVP, and every feature was QA-tested before release. Now, we continue to improve the product on a monthly basis.

The Summit team are smart, knowledgable and engaging and made the project fun from the first briefing call. Maybe we could've figured out how to build our Mybridity website in-house (we've seen the adverts!) but I'm so glad we didn't go down that path. We made more progress in less time working with Summit and, as a result, have a growing pipeline of projects.

Roger Walker's Review Sourced from Google
When we came up with the idea of a web portal for searching and booking experiences and activities from across the county, it was clear that a quality, bespoke website was going to be crucial to our business model. The team at Summit worked hard to understand the concept of what we were trying to achieve, helped design our logo and corporate identity and then worked tirelessly to build a robust website for us. They continue to support our ongoing development, offering friendly and knowledgeable advice. Summit are well worth contacting to discuss a new website build, or to offer a boost to your current site

An absolute pleasure to work with. The team totally understood our brief from the outset, they spent time getting to understand our business and our brand and then seamlessly bought our website to life and exceeded expectations. The entire project ran smoothly and with ease from our side. Their ability to be creative and take our requests and bring them to life was exceptional.

Varinia Peñaloza Rivera's Review Sourced from Google
We worked with Show + Tell to build an innovative website that could elevate our brand through motion and animation. We needed a modern, scalable CMS built on a headless architecture to support future growth — and they absolutely delivered.
Despite a very tight timeline, the team handled the full website build, CMS setup, front-end development (using Next.js), micro-animations, and launch management smoothly and efficiently. Thanks to their close collaboration, daily progress calls, and hands-on project management, the launch was on time, fully tested, and technically high-performing — exactly what we hoped for.
What impressed us most was their can-do attitude and genuine commitment to achieving the best outcome for us. They were honest, upfront, and clearly experts at what they do, offering best-practice advice throughout. Even last-minute changes were handled without any drama — just smart solutions.
We couldn't be happier with the experience and are already looking forward to working with Show + Tell again on our next project!
Highly recommend.

It's been an absolute pleasure working with Show + Tell. We quickly formed an excellent relationship and the new brand identity created by Show + Tell really stands out in the marketplace and reflects the values we wanted to share within the industry.
The ease of usability and design of the website has enabled us to showcase our service offering and available courses in a really engaging way. The whole team is excited to see the results this new website will deliver.

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.
