      Fantastically positive and driven team who on every interaction you just know care deeply about a) what they do b) what they deliver and c) ultimately the experience the end user will have. Hugely impressed with their personal, creative and energy driven approach at the pitch stage, I commissioned 3SC to help us better scope an app. Their task was to take an in-house developed app prototype, and turn it into a fully fledged technical specification with user stories, MoSCoW prioritisation, costs, and an updated look and feel; all done with audience need at the heart. Myself and the wider team have nothing but very good things to say about 3SC. When reflecting on an agency to work with, loads say they can do it, some can actually do what they say they can do, even less do it in the spirit of real partnership and mutually respect/drive. 3SC do all of these excellently. I highly recommend them.

      Priyanshi Verma's Review Sourced from Google

      Unprofessional, Mentally Draining, and Disrespectful Work Culture My overall experience with this company was extremely toxic. During my short tenure, I observed several deeply unprofessional practices that left a lasting negative impact on me: • Salaries were often delayed, without prior communication or explanation. • There were unexplained deductions in monthly salary, and any attempts to raise concerns were either ignored or dismissed by HR. • The HR department was shockingly rude. I personally witnessed employees being humiliated or emotionally broken when they decided to resign — some even left in tears. • No proper Full and Final Settlement (FNF) or professional offboarding process was followed. It’s like once you resign, you’re treated as if you never existed. • Even after resignation, the company continued to send intimidating and threatening emails and begging for small amount of money like 20k, showing a complete lack of empathy — especially towards people who were already in a tough personal or financial situation. If you’re considering joining, please rethink carefully. Make sure everything is documented in writing — verbal promises mean nothing here. A company’s real face shows not when you join, but when you try to leave. And unfortunately, this one shows zero professionalism, zero compassion, and zero respect for employees.

      One of the worst organisation I have ever experienced . Exit process is worst moreover company doesn’t respond on your final f&f queries and literally one has to chase to get their full n final payment. Depending upon clients requirement organisation and their leaders push their employees and even salary is deducted if it is not billed as per clients need. Pathetic to be honest. Lala companies are doing better than this in country.

      On behalf of AES Global Ltd - Moving our app development locally was a key focus for us in 2020. After extensive research into local companies and speaking to them all Ali, Danielle and the whole team at Sugar Rush most definitely came out on top. Their company culture and attention to detail was what caught our eye first which was followed closely on their project management skills. We are currently working on our 4th project together and i am still amazed with their dedication to learn our product inside out so they truly understand how it should function with the app and provide new ideas and better flows than what we had before. We have dealt with a large number of different colleagues within Sugar Rush and every single one of them are a credit to the company and provide a brilliant customer experience. Here is to the last 2 year partnership with many more years to follow. Thank you Sugar Rush for your partnership and helping to modernise and optimise our app platform.

      This is not a trustworthy, ethical or stable business. Studio republic abused the furlough scheme, amongst other things they hired a new account manager while still using furlough for the current account manager. Avoid at all costs!

      We chose Studio Republic to build our new website as they had a great track record of working with similar non-profit environmental organisations like ourselves. They provided an excellent service from start to finish and were a pleasure to work with. Our finished website not only looks great but it has also streamlined our processes which gives our members and staff a much better user experience.

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.
