What information do we collect about you?

We, or companies who work for us, collect information about you when you register with us, place an order for our products and services, sign up to one of our newsletters or get involved in our campaigns or Which? Mobile. We also collect information when you complete our surveys, provide feedback or reviews, send us enquiries or enter our competitions. This may cover anything from your contact and delivery details to payment information, or your responses to questionnaires we’ve sent you and feedback you’ve provided.

We also collect information about your use of our websites, and how you arrived at our website in the first place. This can include what links or adverts of ours you’ve viewed or clicked on to reach us, or any search terms you’ve used. We can also see which pages of our website have been viewed by you and for how long. All this information helps us tell what content is popular with our customers so we can prioritise it.

Online, we mostly use cookies to collect this information about you. Please see our cookie policy for further information.

How will we use this information about you?

We collect information about you to process your order, manage your account and, if you agree, to let you know about our products, services or campaigning work that we think may be of interest to you. If you use Which? Mobile, we may email you if there is a problem with your comments.

We also use this information to decide what content you’re interested in, measure the success of our marketing campaigns and to better understand our customers.

Will you pass my information on to other companies?

We do use other companies to process your data on our behalf, to ensure that we can fulfil all our obligations to you. We only choose those companies who prioritise the protection of personal data and who pass the strict organisational and technical security standards that we set. These companies include those who do the mail-outs of our magazines or those who help us host our websites.

The only other times we will pass your details to anyone else would be where we have to for fraud or other legal purposes.

We will never pass your details (email, address, telephone, IP address, cookie details etc.) to any third parties for marketing purposes.

How long will we keep this information about you?

We will only keep information about you for as long as we need to. We make sure that any companies which process your data on our behalf do the same. We have an internal retention policy where there are varying retention periods for different categories of information depending on our legal obligations and whether there is a commercial need, such as answering member account queries.

After a retention period has elapsed, the data is deleted.


We would like to send you information about our products and services which we think may be of interest to you. If you have consented, then this may include emails. Please note that there is always an unsubscribe link in our emails which will take you off our distribution list, or you can contact us at any time.
