About these results

  • CompareBroadband.com is a price comparison website. We display broadband deals from broadband providers across the UK, and allow you to compare tariffs based on factors such as their pricing, speeds, technology type, and more. To purchase a broadband plan, click "View Deal" and complete the transaction on the provider's website.
  • Displayed prices assume that payment is made via direct debit. Some providers may charge higher costs when payment is made using other methods.
  • Some broadband providers have mid-contract price rises, meaning the monthly cost on a given tariff can increase at certain intervals during the contract period by a specific predetermined amount. When a mid-contract price rise is in place, this is shown on our website at the bottom of each deal card.
  • In the filters shown next to the comparison results, a "Provider" is a company that you buy broadband from. Each Provider uses one or more types of "Infrastructure", which is an underlying broadband network used to deliver internet service. For example, BT and Plusnet both use the Openreach network. Using our website, it is possible to filter tariffs based on Provider or the underlying Infrastructure that they are using.
  • The default "Popular" sort method sorts deals based on the lowest monthly cost, but with certain popular and/or sponsored deals interspersed in the rankings based on manual placement at our editorial team's discretion. These popular deals are prioritised based on our subjective assessment of their market popularity, and their price/value competitiveness compared to other deals on the market. Other sort methods are available using the drop-down menu at the top of the provider filters, including "Lowest monthly cost", "Lowest upfront cost", and "Highest download speed".
  • By default, deals are displayed with a minimum download speed of 100 Mbps. To view all deals, use the "Download Speed (Mbps)" filter next to the deals displayed.
  • In some cases, prices and deals displayed are available only to those who are new customers to a given broadband provider. They cannot be taken up by existing customers re-contracting or changing their plan.
  • At times, broadband providers sponsor certain deals to display higher in the "Popular" sort ranking on our website. When a deal is sponsored, it is labelled as "Sponsored" on the deal card. Choosing a sort method other than "Popular" resets deal rankings so that sponsored listings do not receive priority placement.
  • We make every effort to ensure that prices, contract conditions, and other terms displayed on our website are always up-to-date, but we do not guarantee that all data is always completely correct. Make sure to check the full terms of a given broadband deal on the provider's website before buying.
  • Our website does not necessarily contain all broadband deals from all given providers on the market at any given moment.

FAQs

  • What is CompareBroadband.com?
    • CompareBroadband.com is a comparison website that collates data on broadband deals from major providers across the UK, allowing you to find the best plan for your needs, available at your address.
  • How do you rank broadband deals?
    • By default, broadband deals are sorted by popularity, based on deals with the lowest cost, and plans that people are often clicking on or buying. Sponsored deals can also appear higher in the rankings - these plans are labelled as "Sponsored". You can also choose to rank deals based on the lowest monthly cost, lowest upfront cost, or fastest download speed using the "Sort by" option next to the deals display.
  • How do I switch broadband provider?
    • In general, you can switch broadband provider simply by placing an order for a new broadband plan on a broadband provider's website. Once you place an order, the new provider will handle the cancellation of the old connection on your behalf under Ofcom's one-touch switching scheme. Next, your new provider will organise a time with you to send an engineer to set up your new connection if necessary, or ship you a router in the mail if self-setup is possible. On the switchover date, you'll go live with your new broadband plan, and your old service will cease, helping to prevent any downtime for your broadband connection. There is typically a 14-day cooling-off period after placing a broadband order in case you change your mind.
  • Will I have to pay any fees to leave my current broadband provider?
    • In general, you do not have to pay a fee to leave your current broadband provider as long as you are not in a fixed-term contract with them. Meaning, your initial contract period has expired (which usually occurs 12, 18, or 24 months after buying) and you have not renewed the contract, meaning you have not entered into a new fixed-term agreement with your current broadband provider. If you are in a fixed-term agreement, you usually have to pay a cancellation fee before you can leave.
  • What is the difference between broadband providers and broadband infrastructure?
    • Each broadband provider in the UK sells service delivered using a certain type of infrastructure, also known as a broadband network. For example, BT uses the Openreach network, and Sky uses both the Openreach and CityFibre networks. We allow you to filter broadband deals by provider (seller) and infrastructure (network), in case there is a particular broadband network you would like to use. But if you prefer, you can just filter deals by provider as well.
  • What broadband speed do I need?
    • The exact broadband speed you need depends on how many people use the internet at home, and what sort of activities you do online. For example, streaming high-definition videos requires more bandwidth than regular web browsing does. For one to two people, a 100 Mbps download speed should be plenty, but you might want 200-300 Mbps or more as a family with a lot of people online. To get a more exact idea of what download and upload speed it's worth paying for, given how your household uses the internet, use our internet speed needs calculator.
  • How do mid-contract price rises work?
    • Some broadband providers increase the monthly cost of their plans during the contract period. Usually, the price rise is laid out in pounds and pence when buying a given broadband deal, so you know how the cost will change during the contract period before you commit. If the increase is not laid out ahead of time, and the provider changes their pricing mid-contract, you can generally leave the agreement without paying an early termination fee. Usually, price rises take place annually, often each April, meaning if you buy a 24 month contract, there will generally be two mid-contract price rises to plan around. In saying this though, some broadband providers, often smaller ones, offer tariffs with no mid-contract price increases.
  • Which broadband providers can I use at my address?
    • There are now dozens of different broadband networks and hundreds of different providers serving different parts of the UK. To find out which options are available at your address, type in your postcode at the top of the page, select your address, and browse the different deals available.
  • How can I save as much money as possible when buying?
    • To save money when buying broadband, we recommend avoiding add-ons such as inclusive landline calling minutes, WiFi extenders, and pay-TV services if you don't really need them. Also, avoid paying for more bandwidth than you need, and make sure to use CompareBroadband.com to view the different deals available at your address before committing to a given provider. It can also be worth considering 5G internet services instead of using fibre broadband to save money, and you may also be able to get a cheaper, discounted broadband deal using a social tariff if you are receiving certain types of benefit payments at the moment.
  • What is the difference between FTTC and FTTP broadband?
    • Most modern broadband plans are delivered using fibre-optic cable, which is laid underground from the local broadband exchange. Fibre is either laid just to the cabinet in your street (fibre to the cabinet, also known as FTTC), with copper bridging the gap from the cabinet to your property, or more commonly, fibre is laid all the way to your house (fibre to the premises, also known as FTTP). While FTTC typically offers maximum download speeds of up to 100 Mbps in most cases, FTTP normally offers 1,000 Mbps or even sometimes up to 10,000 Mbps (10 Gbps).
  • What is 4G/5G internet?
    • Rather than using fixed cables in your street, some broadband providers use wireless internet technology to connect to the internet, just like your phone does. These plans still come with a WiFi router that creates a hotspot you can use to get online, but rather than plugging into a wall socket, the router comes with a SIM card, and connects to the mobile network. Wireless internet plans can be cheaper than fibre broadband, but it's important that you have good mobile network signal in your area to ensure you get good speeds when using this technology. This is why many 4G/5G internet plans come with more generous return policies, allowing you to test the speeds at your house before committing to the length of the contract.

Is 100 Mbps enough speed for me?

100 Mbps is enough bandwidth for smaller households of 1-2 people who are not heavy internet users. If you are a family with younger children who are not online very often, this type of internet plan can also work.

The main issue is that if you need to perform very large file downloads or uploads on a consistent basis, having just a 100 Mbps plan can make this process a bit inefficient. You may want faster speeds if performing these sorts of large downloads or uploads on a consistent basis.

For doing things like uploading files to iCloud or Google Drive, the main problem with these types of broadband deals is the upload speed is often significantly lower than 100 Mbps – generally around 15-20 Mbps or so. As a result, large uploads can take a long time, but most of us download a lot more data than we upload to the internet, so this isn’t a problem in most cases.

To get a more accurate idea of how much broadband speed you need, use our internet speed needs calculator.

How much does a 100 Mbps broadband plan typically cost?

100 Mbps broadband deals typically cost about £23 to £36 per month initially, though this can rise during the contract when mid-contract price rises are in place. These price rises will be laid out ahead of time by the provider when you buy.

Is it worth paying more for 200 or 300 Mbps?

It can often be worth getting a 200 or 300 Mbps broadband deal compared to a 100 Mbps one, because they don’t typically cost that much more.

This is especially true if you often make large file downloads as we discussed above, or need a faster upload speed.

Use the filters at the top of this page to find deals with a faster download speed, and compare their pricing to what you’d pay for a 100 Mbps plan.

Which broadband providers offer 100 Mbps plans?

Many broadband providers no longer offer 100 Mbps broadband plans, because fibre broadband technology has advanced to the point where fast speeds are cheap and widely available.

You might find that most broadband providers have a 150 or 200 Mbps average download speed advertised on their slowest tariff.

However, Vodafone, NOW Broadband, and a few other providers still offer this type of download speed.

BT and other major Openreach broadband providers offer plans with download speeds below 100 Mbps, but only in areas that can’t get full fibre broadband.

What to look for in a 100 Mbps broadband deal

When comparing broadband deals in this speed range, consider:

  • Upload speed – because it can sometimes be a bit low on 100 Mbps plans. Deals with matching download and upload speeds are a great choice, but can be rare to find in some areas.
  • Mid-contract price rises – some 100 Mbps deals may seem cheap to begin with, but will get considerably more expensive over the life of the contract.
  • Whether 5G internet makes more sense than fibre – often, you can get much faster download speeds using wireless internet technology compared to fixed-line broadband at this sort of price range. You might be able to get 200-300 Mbps with 5G for a lower price than 100 Mbps on fibre.
  • WiFi routers – some plans have better WiFi tech than others, though this is less important on a slower broadband plan.
