ELEKS Reviews & Testimonials

Software Development Review from John Armstrong
ELEKS was able to take our vision and help us deliver an app that empowers retail shareholders to make their voices heard. They’ve brought a depth and breadth of technical expertise and user experience design to challenge us on our assumptions on how people would want to interact with the app. From a mobile development perspective, we wanted to go to market with both an Android and an iPhone simultaneously.

Software Development Review from Mark Battcock
We are very happy with our ELEKS partnership; the dedication of the team is exceptional. We would certainly recommend ELEKS and would be happy to work with them again. In fact, they continue to be our partner for the 2nd phase of the CDX project to add even more customer services to the website.

Software Development Review from Huntly Christie
What impressed me about ELEKS is the culture. There is a very strong culture of discipline and performance, and software is a profession where discipline is very important. Good software development can only happen with a strong work ethic, and I think the ELEKS team really understands that.

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.
