WPJ Heating is a leading plumbing and heating company based in London. WPJ Heating approached Appoly to design and develop Clipfix, an app connecting plumbers and heating engineers with customers facing issues at home.


WPJ Heating found that they were being called out to homes to solve plumbing and heating issues that could have been fixed by the customer themselves, providing that a small degree of technical advice was offered by the engineers.

Our Solution

Thus, WPJ Heating approached Appoly to develop a mobile app that would solve this issue and leverage the power of technology to connect the engineer with the customer in real-time through live video chat functionality, including a flashlight and screenshot abilities.

Our Process


Appoly designed a prototype app to map out the most efficient user journeys for both the plumber/heating engineer and the customer.


We initially developed Clipfix on iOS to test the market, considering iPhones and iPads still dominate the market in the UK. Following this, we began working on an Android version of the app to maximise accessibility for WPJ Heating customers.
