BigChange at the Heart of WarmZilla’s Online Heating Revolution

Leeds, 01 August 2023 – WarmZilla, the national heating and home services innovator, is driving expansion with a cloud-based job management system and mobile working app that has already increased productivity by 50 percent. Supplied by BigChange, the 6-in-1 system has boosted efficiency and also enabled WarmZilla to double the size of its network of installers. Through an online platform, WarmZilla makes it easier to buy and install everything from boilers and EV chargers to Smart Home gadgets and security systems. Headquartered in Cardiff, WarmZilla is putting BigChange at the heart of its plans to become a household name.

WarmZilla’s founders, brothers Matthew and Rhys Powell, had the vision to simplify the way boilers were purchased. Armed with a massive flow diagram they went about putting together an e-commerce platform that provided a simple solution to a complicated problem. An online survey guides customers through a series of questions relating to their existing heating solution and their house configuration before recommending suitable boilers. Once chosen optional extras can be added and an installation date selected – and that’s where BigChange comes in.

“BigChange does the heavy lifting!” commented Matthew Powell, co-founder and Managing Director of Cardiff-based WarmZilla. “It takes the stress out of day-to-day tasks by streamlining and automating work flows and by seamlessly integrating with our online presence and other business management systems. Unlike other systems BigChange is extremely scalable, it’s designed to integrate and it’s built to be updated with new functionality and improved performance continuously added.”

WarmZilla works UK-wide with more than 500 fully vetted and approved WarmInstallers and is always looking to add more quality service providers to its network. Using the BigChange job management system, which incorporates customer relationship management (CRM), job scheduling, live tracking, resource management, financial management and business intelligence, WarmZilla can automatically allocate new installations based on engineer location and availability.

Pre and post implementation job sheets are digitally produced and sent to the engineer using the BigChange app. Once filled-out onsite, complete with date, time and location stamped photographs and customer signatures, the job sheets are shared with the back-office BigChange system where the information is used for invoicing and customer follow up.

“When we started, we had everything custom built, in accordance with our flow diagram and our vision,” added Rhys Powell, co-founder and Operations Director of WarmZilla. “However, as we have expanded our product offering and our service coverage, we have learnt that to be a jack of all trades and master of none is not an ethos that sits well with us.

“BigChange, like us, is the best at what it does. Using BigChange we can manage the workflow from the moment the customer check’s out to the point where they add their signature to the job sheet and work onsite is complete. With up to 100 jobs a week, that’s no mean feat!”
