Essential new guidance on legislation and best practice is now available for businesses installing renewable energy, green heating and energy saving measures in domestic premises.

As growing numbers across the UK race to install energy-efficiency devices in their homes under the multibillion-pound net zero initiative, there will be an ever-increasing need for businesses equipped and qualified to meet demand.

Protection of consumers needs to be the top priority for all businesses in this sector. To protect them, and to ensure that devices like heat pumps, solar panels and batteries are appropriate, functional and environmentally friendly, traders must ensure they understand their responsibilities under consumer protection legislation.

So, to help these traders, Business Companion has launched a fantastic new guide: Domestic Energy Saving. It is packed with practical information about how these businesses can meet their legal obligations and make the most of the opportunities represented by the UK’s push to net-zero carbon emissions.


As the domestic energy-efficiency sector involves operating in people’s homes and selling technology with which many consumers are likely to be unfamiliar, there is a particular need to be aware of issues relating to consumer vulnerability, and guide has a focus on this.

The resource comes in three parts. Part 1 explores matters of promotion, covering the practices that businesses should avoid around energy-efficiency performance claims, marketing and advertising. The section also gives an easy-to-understand breakdown of the key aspects of relevant consumer protection law. It also provides useful links to the trade bodies and consumer codes that operate in the domestic energy sector.

In Part 2, the guidance explores how traders should engage with consumers before, during and after the installation of domestic energy-efficiency measures. Helpful and practical guidance on what information should be included in a contract, descriptions of practices that should be avoided is given. It also discusses how a business should provide after-sales service, to ensure that customers are happy and satisfied.

To help businesses deal with situations in which customers are not satisfied, Part 3 of the guidance outlines the complaints and redress processes traders should follow, including effective complaints handling procedures and the role of Trading Standards in helping to resolve disputes between businesses and consumers.

The guidance concludes with links to additional useful resources such as the relevant industry standards, the Green Claims Code and the CMA’s consumer guidance on buying green heating and insulation products, as well as links to the full legislation explored elsewhere in the guide.

Like all Business Companion guidance, Domestic energy saving has been written to be clear, concise and practical, and is suitable for businesses of all sizes that need to quickly find accurate and reliable answers to issues they may face while going about their work.

Business Companion is a Government-backed service provided by the Chartered Trading Standards Institute (CTSI).

John Herriman, Chief Executive of CTSI, said: “Businesses, consumers and bodies such as Trading Standards all have a role to play in making the UK’s transition to net zero run smoothly and effectively. It is in everybody’s interest to ensure that the practices businesses follow are lawful and honest.

“The domestic energy saving sector has previously been subject to misleading and exaggerating claims, which in the short-term leave consumers vulnerable to being exploited and undermines confidence in the net zero agenda, and in the long term do more harm than good in efforts to create a more environmentally sustainable society.

“This guidance has been designed to help businesses avoid common mistakes, and it provides some really useful tips on how businesses can build a strong reputation and make the most of the opportunities that come with good customer service and honest business practices.”
