How the best & worst firms are ranked

Every three months, Ofcom provides its breakdown of complaints per 100,000 customers that each major provider attracts. 

These stats take some time to put together, so the latest figures that we're discussing in this article cover the period between January and March 2025.

If your provider features near the top of the complaints list, or you simply want a cheaper deal, make sure you compare broadband deals in your area today.

It's straightforward and you could save hundreds, especially if you bundle your broadband with your landline and pay TV provider.

As a final point, while the figures below might sound low, it's worth remembering these aren't just for complaints made to broadband firms: they are issues that have been escalated to the regulator because customers have been unable to get their issues resolved directly with their provider.

The actual number of unhappy customers will be far higher as these only cover the documented, extreme cases.

As a case in point, Ofcom's report claims that one in five broadband customers had a reason to complain to their provider over the last year.

It means TalkTalk has now finished last or joint-last for three quarters in a row, with service issues consistently cited as the main reason behind complaints.

Virgin Media racked up the second most official complaints with 12 per 100,000.

EE, Vodafone and BT (all 11) were the other firms to come in above the industry average of 10.

Switching broadband is a lengthy farce, but it's still absolutely worth it

Should you switch even if you're happy?

The above figures give you a good idea of which firms have the worst track records for treating customers fairly. 

But even if you are with one of the better performers, it's seriously worth considering switching if you've been with them for more than a couple of years.

Why? Research has highlighted how broadband firms are charging existing customers the best part of £200 a year more for the identical service being offered to new customers.

So even if you're happy with your service, you should still ensure you aren't getting ripped off by regularly shopping around for cheap broadband deals.

Also, if you're currently mid-contract and your provider is planning to hike prices, there are new rules that should make it easier for you to ditch them penalty-free, which you can read about here.

 As a final point, if you're in receipt of Universal Credit you should definitely check out social broadband tariffs, which could save you a lot of money. Read more about it here.
