What our clients say
Chilliapple accelerates company success Chilliapple have been the fuel in our companies engine for the past year by helping us to develop the signature product and get it launched. Avatar is ready for use thanks to Chilliapples tremendous technical delivery design and delivery process.
Jeff Nogosek Avatar
Their communication skills and ability to complete the project within budget and timescale were impressive.
After the launch of the website, the client received feedback from customers concerning a better UX, and Chilliapple Ltd. was able to update easier than before. They communicated through Campfire and had weekly updates through Zoom meetings. Overall, the team provided a good value for the budget.
Luisa Coates Thermapen
Good Knowledge of Magento: Chilliapple was recommended to us for their Magento knowledge which has proved to be excellent. We worked with Bowo and Vipin to migrate and upgrade our existing Magento shops to a new UK Fast server with additional features and plug ins installed resulting in a faster admin than we previously had. I would recommend Chilliapple for Magento especially multiple shops.
Steve Long Merlin Workwear
Great work with the team at Chilliapple. They undertook our website maintenance from a previous developer and they have managed to accommodate many of our initial needs, including an upgrade to Magento 2.4.
Since then, we have overcome many more requests to improve website and shopping functionality and while I personally will not be overseeing their work anymore, I trust though that Versapak are in safe hands and that they can meet any new challenge that may arise.
Jeremy Graham Versapak
I've worked with many web agencies in the past and ChilliApple certainly shine above the rest. Our account manager Bowo has been extremely attentive and pro-active, without whom we would not have been able to deploy our Magento 2 migration by the end of 2020.
We're very pleased at the hard work and patience that Bowo and the development team have put into this project, especially as we were working long hours towards the end. I look forward to continued work with ChilliApple in 2021!
Laura Lam Phoenix Medical
Our website is built in Prestashop, and finding credible developers to maintain and progress the site was very difficult once we had made the decision to move on from our current developer.
Chilli Apple initially upgraded and re-themed our site to a very high standard with excellent communication throughout. We went live with the update (which was quite a major undertaking as it had not been done for some time and a lot had changed) right at the beginning of the COVID fiasco. [+]
Kieron Miller Skirting4u

Frequently Asked Questions
Empty tag
How do I choose the right software development agency in the UK?
Start by analysing how well the agency understands your business. Look at the:
- Kinds of problems they’ve solved
- Industries they’ve worked in
- How they approach projects
- Technical proficiency
- Years of experience
A UK-based team can make collaboration easier, especially if you need regular check-ins or in-person discussions.
How much does bespoke software development cost in the UK?
Costs vary depending on what you’re building. The final quote depends on what’s included, how changes are handled, and what happens after launch.
How do I communicate with your team during the project?
You’ll have a single point of contact throughout the project. This helps ensure clear communication throughout the project. We will ensure you get regular updates, and you can easily raise questions or request changes.
Will my software comply with UK data protection laws such as GDPR?
Yes. We ensure data protection is built into the way the system is designed. This includes secure data handling and controlled access. We also deploy the right processes for storing and using data.
Do you build AI into the software you develop?
Yes, increasingly, that's the default. We embed AI directly into bespoke platforms. This includes:
- Intelligent process automation
- Document and data extraction
- Predictive analytics
- AI chatbots and copilots
- Generative AI integration
We ensure the right guardrails for UK data privacy and enterprise compliance. Need AI as the core of the product or as a workflow enhancement? We'll recommend what genuinely adds value.
How long does bespoke software development take?
The project timeline of bespoke software solutions depends on scope:
- MVP or internal tool: 8–12 weeks
- Mid-size business platform: 3–6 months
- Enterprise system with integrations and AI: 6–12+ months, often delivered in phases
We work in agile milestones, so you'll see working software early and regularly.
Do you provide ongoing support and maintenance after launch?
Yes. Launch is just one stage of the lifecycle. Ongoing support covers updates, improvements, and ensuring the system continues to perform as your business grows. We can also adjust the level of support based on your needs.
