The cost of high-speed broadband deals has fallen in recent years, so it’s worth checking out your options.
100Mbps is at the high end of “superfast” but doesn’t count as “ultrafast”. It’s not the very fastest option out there, but it’s definitely enough for a household where several people want to make video calls, surf the web and watch streaming services.
You only get speeds of 100Mbps or more if your home has a full fibre connection, also known as FTTP. This isn’t available everywhere yet. Put your postcode into our address checker and we’ll only show you speeds you can actually get.
There are a wide range of providers in the UK that offer 100Mbps broadband, including:
We compare 100Mbps broadband deals from 27 providers. Make sure you check your location when comparing 100Mbps broadband deals, as some providers won’t offer this speed in your area.
It’s not the fastest speed out there. Don’t be misled by the “superfast” tag. The “superfast” category technically starts at 30Mbps1, which almost all UK homes achieve these days.2 According to Ofcom, the average maximum download speed for UK broadband in 2024 was 223Mbps3. So although 100Mbps would have been considered incredibly fast just a few years ago, it’s now actually below average .
You need a full fibre connection. Speeds of 100Mbps aren’t possible if your home is on an old ADSL line or part fibre/FTTC.
For many normal internet users, 100Mbps still hits the sweet spot in the trade-off between speed and price.
Our bandwidth calculator will give you a realistic idea of what broadband speed you need. For most households, 100Mbps is more than enough. Input your details and see what the calculator recommends.
100Mbps is no longer above average for a maximum speed, because broadband speeds in the UK keep increasing. But it should be more than enough for most internet users.
Online multiplayer gaming is one of the most bandwidth-hungry activities you can do, and the experts at Tom’s Guide say that speeds of 50-100Mbps are enough for this.4
100Mbps is also more than enough for using streaming services like Netflix or Apple TV.
Tom’s Guide specifies that 100Mbps can comfortably support three to five devices, even if you’re doing high-bandwidth things like gaming. But it could start to struggle once you get more than five devices sharing the same connection. For five or more consoles or laptops, you might need 150Mbps or more.4
We’re a comparison site dedicated to finding our users the best deal. Once you’ve put in your postcode and got the results for your address, you can sort them by price.
But before you rush to sign up for a deal with a low monthly price, watch out for mid-contract price hikes . Most broadband providers put up their prices at least once a year, so the cheapest today might be a lot more expensive next April. Providers have to be transparent about planned price rises, so this information will be in the details of the contract. Read it and take it into account when you’re comparing broadband deals.
If you’re outside the minimum term of your contract, switching broadband is easy.
You don’t need to tell your old broadband provider that you’re leaving. Your new provider will do that for you.
If it’s been a while since you last switched, you can probably get much better speeds without paying much more - or even save money. It only takes a few seconds to see what your options are, so what are you waiting for?
