From assessing your roof and comparing installers to weighing up the benefits of battery storage, we guide you through the key decisions you’d have to make before taking the plunge.

Weight loss injections like Ozempic, Monjaro and Wegovy are skyrocketing in popularity but are online pharmacies following the rules?
In this episode, we sit down with Which? senior investigative researcher Sara Spary to discuss her investigation into online pharmacies. She reveals how easy it is to bypass safeguards by using fake GP details and fabricated health conditions to buy these prescription drugs.
We also dive into the "cosmetic" illusion created by aggressive social media marketing, how the high street is reacting and Sara shares crucial advice on how to avoid dangerous counterfeit jabs online.

Whether it’s rip-off pricing, ticket touts or dangerous products being sold on online marketplaces, the government’s Department for Business & Trade is responsible for protecting consumers’ best interests. But is it doing enough?
In this episode of Which? Money, we sit down with Kate Dearden, the minister for employment rights and consumer protection to ask what work the government is doing to ensure consumers aren’t being ripped off or put at risk when buying products and services online or in-store.
We take the opportunity to highlight some Which? investigations that highlight why the government needs to do more to strengthen consumer protections, and ask why more wasn’t done in last month’s King’s Speech to stamp out ticket touts.
Plus, Sue Davies, Which?’s head of consumer rights analyses the minister’s answers and tells us what more we want the government to do.

Say goodbye to your inefficient tumble dryer when it breaks, as heat pump models will soon become the norm.
In this episode of Which? Shorts, we explain why the government is introducing new regulations that will mean inefficient tumble dryers - mainly condenser and vented models - will disappear from shops on the high street and online.
We explain how the raising of efficiency standards will drive innovation and ultimately cut energy bills. The slightly higher upfront costs of such dryers are quickly offset by lower running costs, and well-targeted standards can help drive these prices down further.
This episode is read by Becki Jakeman and is based on an article she wrote, originally published in the June 2026 issue of Which? magazine.

Copy trading is a fast-growing trend, where investors discuss portfolios and markets, potentially influencing investment decisions. Copy trading takes this a step further, as investors mirror the portfolio and trades of another user of the platform.
In this episode of Which? Money, senior researcher Megan Thomas explains how copy trading works, how risky it can be, and how certain trading platforms are becoming destinations for those who think it’s an easy way to increase the value of an investment portfolio.
Megan shares the result of her experiment, which saw novice investors try out social trading and copy trading platforms for the first time, to track how drawn users were to investors who already had tens of thousands of other investors following their every move.
Plus, Simon Weidenholzer, professor of economics at the University of Essex, talks us through the history of the trend, and describes how giving people the option to directly copy others can lead to a significant increase in risk taking.
