If you are unsure whether a repeater is legal to use, you can email us at for advice. We will update this list from time to time. These are not repeaters that we promote or endorse, simply those that have been tested against our requirements by an accredited test house. To help you choose the right repeater, Ofcom has published a list of repeaters that we understand meet the technical requirements of our licence exemption regime. So when choosing a repeater, make sure you purchase it from a reputable retailer.

We realise it can be difficult to understand the difference between legal repeaters and the range of illegal devices advertised widely online – especially since advertisements for illegal devices often claim they are properly approved. Repeaters that do not meet those requirements remain illegal.

We now allow repeaters that boost the signal of more than one mobile operator at a time, provided they meet our technical requirements. We had previously only allowed repeaters that boosted the signal of one mobile phone network at a time. In May 2022, Ofcom extended the range of static indoor repeaters available for people to buy and install themselves without a licence.
