      Staff Augmentation Review from Dzmitry Novikau

      I worked with Kernelics on a crypto project where we needed help with both design and development. From the beginning, the team was easy to communicate with and clearly understood what we were trying to build. The designer improved our initial ideas by making the user experience more intuitive. They suggested better ways to structure the navigation and user flow, which helped reduce friction and made the product easier to use. We also brought in one of their developers, who worked alongside our existing team member. They collaborated well, completed the work on time, and handled some challenging parts of the exchange functionality without any issues. Overall, Kernelics delivered quality work, stayed within budget, and were professional throughout the process. I’d recommend them to others looking for a reliable design and development partner, especially for crypto or fintech projects.

      Web Development Review from Stsiapan Kolesau

      I CEO at the construction company specializing in modular buildings and their components. With years of experience and multiple projects, we decided to expand our online presence beyond our two existing landing pages. We needed a corporate portal to showcase products, manage content easily, and dynamically calculate product costs. On a recommendation, we chose Kernelics, and their organized approach and clear task division impressed us from the start. They began with an in-depth analysis of our needs and a competitive review. For the design, we requested a minimalist style, and the results were spot on, requiring only minor tweaks to meet our expectations. For development, Kernelics selected React, Next.js, and TypeScript, with Strapi for the admin panel. They also integrated Google Sheets to handle dynamic price calculations, enabling instant updates on the site by simply modifying the spreadsheeta feature weve found incredibly useful. Now, two years later, the portal continues to support our growth, and were planning new developments for our main site. Kernelics stood out for their transparent approach and professionalism at every stage, and I confidently recommend them to anyone seeking a reliable web development partner.

      Fintech Review from Dudley Gould ACA

      What set's Alatar.io apart is their team. They are not only experienced product managers, software developers and designers but have a lot of experience building and helping startups. Whilst Altar.io is responsible for all of the tech development, a huge amount of my time with the Altar.io team is actually spent working on strategy, marketing and business development. I highly recommend working with Altar.io.

      We recently had the pleasure of working with Parachute on our new website, and we couldn't be more thrilled with the results! Ashley and Michael were particularly exceptional — both are incredibly professional and friendly, making the entire process enjoyable. In addition to the design, Parachute is also assisting us with SEO, and their expertise is already making a noticeable difference. If you're looking for a web design agency, myself and my colleagues highly recommend Parachute!

      The Parachute team have always provided a friendly and efficient service, explaining things in words non-techies can easily understand. They are always there to help and ready to go the extra mile, even when the issue isn't directly related to the website that they host for you. I can't recommend them highly enough.

      Dan and the team at Corporation pop have reinforced our faith in humanity. Their belief in what Roadbot can achieve has been backed up with the hours and hours of work they've put into the project on a pro bono basis. Pop possess all of the moral values our charity wants to instill in the drivers of the future. Their compassion and willingness to help us make the generational change so desperately needed to make Britains roads safer goes above and beyond anything we would dare to ask. Frankie and Neeve's Road safety academy will be forever greatful and look forward to working with the guys for many years. We are truly humbled by their generosity and proud to share our journey to safer roads with them.

      4 years completed at Digimonk and counting, I can honestly say this is one of the best places I've worked. The team is talented and collaborative, we push each other to do our best work without the toxic competition. I've particularly enjoyed mentoring some of our newer designers and watching them grow. The CEO actually understands design thinking and champions our work across the company. We have our challenging days of course, but overall, I'm proud of what we create here and the supportive culture we've built.

DesignRush sustains a directory of over 40,000 agencies categorized by service category, location, expertise, and reviews. We build our database in two ways:

  • Our dedicated team of agency experts actively searches the web for top-performing companies. We then pull information from their websites, online presence, and client testimonials to verify their status and qualifications prior to listing.

Agencies can also reach out to DesignRush and must go through the verification process prior to being listed.

Frequently Asked Questions

What are the core specializations of custom software development companies in the United Kingdom?

The core specializations of custom software development companies in the United Kingdom generally center around web/mobile app development and advanced digital technologies. Their expertise extends to AI-powered products, cloud solutions (especially DevOps), feature enrichment, and cybersecurity.  

Overall, they provide end-to-end digital transformation solutions and engineer custom platforms and systems that drive competitive advantage and business growth across industries. 

How much do software development services cost in the UK?

The cost for software development services in the UK ranges from £25,000 to £120,000 for small businesses. In contrast, large enterprises undertaking extensive digital transformation or building sophisticated, bespoke systems should anticipate costs starting at £80,000 and potentially exceeding £500,000. 

For startups or businesses aiming to validate a concept, the initial cost is considerably lower. A minimum viable product (MVP) or a proof-of-concept generally falls within the £5,000 to £30,000 range. The final price is ultimately determined by the project's complexity, the chosen technology stack, the developers’ experience, and the geographical location of the service provider, which impacts their hourly or daily rates. 

How do I choose the right United Kingdom software development firm?

To choose the right United Kingdom software development firm, begin by evaluating its portfolio and case studies to make sure they have experience in your required technology stack and niche. Inquire about its process and team structure, to make sure they follow an iterative methodology and that the core development team will be dedicated and accessible for regular communication.  

Finally, prioritize a company with good reviews that reflect a track record of robust post-launch support and good collaboration throughout the project. 

Do software development companies provide ongoing support?

Yes, software development companies do provide ongoing support, maintenance, and updates after the product launch. This post-launch service is important for fixing bugs, maintaining security, adapting to changing user needs, and making sure the software remains stable and competitive. 

How do custom software development companies in the United Kingdom handle project revisions?

Custom software development companies in the United Kingdom predominantly handle project revisions through the Agile methodology. This involves breaking the project into short, iterative sprints, allowing the client to provide feedback and request necessary revisions at the end of each cycle.  

This flow is intended to minimize risk and keep the final product aligned with the envisioned concept, rather than waiting until the end for a major change.
