Problem

Renewable heating is on the rise, but servicing it is stuck in the past.

As the UK shifts away from gas boilers toward heat pumps, a new challenge has emerged: aftercare. Unlike traditional boiler servicing, heat pump maintenance lacks standardisation, availability, and trust. Homeowners are left confused, facing long lead times, unclear pricing, and inconsistent service quality. The transition to clean energy is happening — but the support systems haven’t kept up.

Solution

A modern, subscription-based servicing platform built for the future of home heating.

We worked with Mutha Cuva to build a digital-first platform that brings simplicity and reliability to renewable heating support. Users can sign up, schedule servicing, and manage payments through one clean interface — no calls, no paperwork, no uncertainty. With integrated scheduling, secure payments, and a clear service promise, Mutha Cuva offers a seamless experience for households moving to green heat.

Results

A scalable, service-driven engine powering the UK’s clean energy transition.

In under eight weeks, we launched a platform ready to handle recurring payments, national expansion, and future green finance integration. The result is a high-trust user journey that turns complexity into clarity, positioning Mutha Cuva as a leader in renewable heating support. Early adoption has validated strong consumer demand, and the business is now set to grow with the market.

About the client

Amy Mooney is a strategic founder who sees opportunity in overlooked corners.

After scaling Gas Angel into a subscription-based boiler servicing business, Amy spotted the next big need: heat pumps. The UK’s move toward renewable heating is accelerating but while installations hit stride, servicing is fragmented, confusing, and slow.

Seeing this gap, Amy created Mutha Cuva, a subscription-based service that brings clarity and consistency to clean heating maintenance. No messy callouts. No gaps in coverage. Just dependable, renewable heating service delivered simply.

But she needed more than software development. She needed a strategic partner who understood how to turn a promising idea into a scalable, revenue-generating engine. That’s where Rendr shines.

We aligned with Amy’s vision to build a business-first platform packed with intuitive scheduling, secure billing, and designed to convert curious homeowners into loyal subscribers. With tools like Next.js and Framer Motion for a polished UI, Cal.com for smooth booking, and Stripe for recurring payments, we crafted something that’s as reliable as the service it supports.

Together, we went from concept to launch in under eight weeks laying the foundation for Mutha Cuva’s national ambitions, future green finance integration, and a future where servicing heat pumps isn’t a headache, but a hassle-free subscription.
