Ofcom is the regulatory body which oversees many different aspects of communication services here in the UK, including TV and radio, wireless electronic devices (such as cordless telephones, walkie-talkies, and even smart doorbells), and it even oversees the performance of the Royal Mail. And, of course, it deals with the broadband market, where it works to ensure that consumers are not being overcharged for services or being subjected to bad practices. Ofcom regulates the price of broadband services, and can implement charging controls where necessary, to ensure that customers aren't being ripped off. It also promotes competition between different ISPs to ensure that customers have a good range of options for their broadband services, rather than allowing a single company to gain an unfair monopoly over the British broadband market.
Ofcom is given its mandate by the UK Government, but is an independent body which is funded by money it receives from companies it regulates. UK customers (both domestic and business) can get in touch via Ofcom's website or by telephone if they have any concerns or complaints. If you do have a complaint about your broadband service, Ofcom itself cannot step in to resolve the issue, but will instead direct you to its Alternative Dispute Resolution Scheme, or ADR scheme. These schemes are independent bodies and are free to use.
Ofcom works to make sure that people are able to access broadband services, and, to this end, it is also overseeing the rollout of full fibre broadband across the UK. You can visit its website to find out the latest news about this vital network upgrade.
