What is unlimited broadband?
Unlimited broadband is when your provider lets you make as many downloads as you want, so you can browse the internet and use your Wi-Fi without worrying about whether you’ll hit your allowance each month.
Most providers offer unlimited downloads as part of their standard broadband packages.
How to compare and switch broadband
There are three simple steps to compare broadband deals and switch providers
-
Check you're out of contract
Ensure you're no longer within the minimum terms of the contract length with your current broadband provider. You can find out by looking at your original contract, confirmation email, or by contacting their customer service.
-
Enter your postcode and choose a personalised bundle
We algorithmically sort broadband packages based on your location, the speed you'd get, and how much it costs.
-
Complete your switch
Your new provider should contact your current provider and arrange the switch for you. And you'll receive letters and emails updating you on this.
Do I need unlimited broadband?
While home broadband plans with unlimited downloads are widespread and generally affordable, you might be able to get a cheaper deal if you don’t think you need unlimited access to the internet.
That said, almost all fixed-line broadband connections these days are unlimited. Most Wi-Fi deals with limited downloads are mobile broadband, delivered over 4G and 5G, which is more flexible and doesn't require a phone line.
A good place to start is by working out what kind of internet user you are, which will also help you decide what kind of download speeds you need. Then use our postcode checker to see what you can get.
What kind of internet user am I?
Internet usage is generally sorted into three categories – light, medium, and heavy. The way you use your connection will help you decide what kind of broadband speed and download limits you should get.
Light users: If you only really use the internet for day-to-day activities, such as shopping, emails and banking, you might not necessarily need unlimited downloads or very fast speeds
Medium users: If you regularly browse the web or social media, or occasionally like to stream music, movies or TV, you could benefit from faster fibre broadband and a bigger download limit
Heavy users: If you use the internet often, connect lots of devices to your Wi-Fi, or do heavier tasks such as sharing files, regular streaming or online gaming, quicker full fibre broadband and unlimited downloads will be the best fit for you
How to get a better broadband deal
Whether you're looking for cheap and cheerful or high-spec full fibre broadband, everyone's needs are different. Finding the best deal for you starts with understanding how you plan to use it or if bundling your services lower your monthly bill.
-
Are you still within your contract?
If you're still in your minimum term, you'd be subject to an early repayment charge if you ended your contract early.
If you're out of contract or approaching the end, you can switch without penality.
-
Can you get a better deal for the same price?
A tariff may offer everything you're looking for, but does it come to the right monthly price and offer good value for money? Shop around to find the right tariff at the best possible price.
-
Can you get any bundles, freebies, or cashback?
Many providers offer tempting incentives, such as cashback or gift cards to new customers. These may help bring down the cost of an expensive broadband deal, although you should also consider whether these gifts are as important as factors such as speed and cost.

Broadband explained
What download speeds will I get with unlimited broadband?
The download speeds you get with your unlimited broadband deal will depend on whether your provider offers an ADSL, fibre optic, or FTTP (full fibre) connection.
ADSL: ADSL stands for ‘asymmetric digital subscriber line’. It’s the most widely available type of connection, but it usually offers the slowest download speeds of the three main types – around 10-30Mbps on average
Fibre: Fibre-optic broadband is becoming more widespread, and delivers faster speeds 50 and 300Mbps
FTTP: Available in 57% of UK homes, full fibre (FTTP) connects fibre to your home, rather than just the street cabinet, making for a faster and more reliable connection than partial fibre.2
What other services can I get with unlimited broadband?
Unlimited broadband plans are often bundled together with a landline and/or a TV package. If you use these services, you might be able to save money by opting for one of the following bundle types:
Broadband and phone (landline or mobile)
Many providers also offer incentives such as cashback or free gifts. However, while these can be tempting additions to your deal, the quality of your connection is mort important long term.
