How Which? drives consumer trust and sales growth for Heatable

In 2023, Heatable became endorsed as a Which? Trusted Trader.

After completing an extensive vetting process to join the Trusted Trader network, the team at Heatable began using the endorsement in its email follow-up journey, targeting customers who had completed an online quote but not placed an order. The follow-up email led to a 42% increase in conversions – the company’s highest-performing email to date.

The company, which helps consumers start their renewable journey with solar and battery storage solutions, uses its Which? endorsement across publications, at trade shows and in customer support conversations. The endorsement strongly resonates with UK consumers, providing a clear vote of confidence and demonstrating Heatable’s commitment to quality and trust. It has also helped more customers discover the brand online.

Building on success

A year after its endorsement, and with the launch of the Which? Home Energy Planning Service, Heatable took part in a commission-based member promotion offering Which? members a discount on the cost of solar panel, battery and EV charger installations. The offer was promoted to Which? members through weekly and monthly newsletters, in-content features, podcasts and targeted solus emails. It was also featured within the Home Energy Planning Service.

With revenue of over £2.6 million in 12 months and more than 2,500 panels now installed on UK homes, the partnership has not only been a hugely successful business venture but has also demonstrated how collaborations like this can drive the delivery of carbon-reducing products in the UK. It is making a tangible, real-world difference.

The Heatable team regularly hears from Which? members who discovered the company through the promotion and say they had been waiting for a trusted recommendation and offer like this.

Describing their experience on the company’s Which? Trusted Trader page, one satisfied customer said:

'I chose Heatable because Which? recommended them. I had reservations because they were online only and weren’t going to do a site visit, but I trust Which?, so I gave them a chance.

'The Heatable staff were friendly, knowledgeable and nothing was too much trouble. The engineer was great, too – friendly, efficient, talked through everything with me and left the room as he found it.

'The service I received was faultless.'

Our experience with Which?

Sam Rigby, Director of Heatable, says:

'Our work with Which? has been a resounding success, strengthening both our consumer trust and sales revenue.

'It’s clear to see the remarkable rapport that Which? members have with the organisation, and that trust is immediately reflected in how consumers respond to their offers and recommendations.

'We’re rewarding Which? members with our largest-ever promotion on renewable technology. While this has been a hugely successful business venture, it’s also been a joy to reward such a loyal and passionate membership group looking to save on their bills and reduce their carbon footprint.

'The support and collaboration we’ve received from the team at Which? has been unparalleled. Working with Ceri and Jenny has been a privilege, and we’re incredibly excited to deliver more together in the future.'

About Heatable

Heatable was founded in 2017 by two brothers and helps customers get a fixed price for boilers, solar panels and batteries without the need for a salesperson. Customers choose from a range of fixed-price options and an installation date that suits them. A selected local installer then completes the installation using the products chosen by the customer on their preferred date.

Ceri John, Home Energy Manager, Which? Home Energy, says:

'In September 2024, the Which? Home Energy Planning Service launched alongside an exclusive member offer with Heatable. Heatable is a nationwide-endorsed Which? Trusted Trader, and we have collaborated for over a year on our solar panel member-exclusive offer. We’re pleased to extend this partnership for another year, giving Which? members savings on the installation of solar panels, batteries and EV chargers.

'Over the past year, we’ve built a strong partnership with Heatable, collaborating closely on the initiative to deliver excellent customer service to our members. Through regular meetings and the sales updates and customer insights Heatable provides, we’ve been able to monitor the offer’s strong performance.
