Cordless phone reviews you can trust

We send models from the biggest names in cordless phones for testing in our labs – including BT, Binatone, Panasonic, Philips and Siemens. We test each model to discover the things you’d want to know before you get a phone home – and potential niggles that could leave you kicking yourself after you’ve made a purchase.

Which? is independent - we work for you, the consumer, so you can be sure we only recommend products that perform well in our lab tests. We don't take advertising and we buy all the products we test. This means that as well as recommending great cordless phones, we’re not scared to tell you which to avoid
