We're all keen to shave a few pounds off our monthly bills, so when we're shopping for broadband and find an entry level package that looks the same as the more expensive alternatives, it can prove pretty tempting. Many broadband providers - from the industry's biggest and smallest names alike - offer these. They can be extremely cheap, but they come with pretty hefty restrictions.
Sky make a compelling offer with their cheapest fibre deal. It gives you the opportunity to upgrade to the benefits of fibre broadband and get it completely free for the length of the contract, while paying only line rental. Except there's a catch - you're limited to 25GB of data each month.
BT's lowest priced fibre deal also comes with a 25GB limit, and their cheapest standard broadband just 12GB. Many other providers also impose limits on their most affordable packages, ranging from 100GB down to a paltry 5GB.
Not only do these limits restrict how you can use the internet, they can also prove more expensive in the long run. Exceed your limit on BT, for example, and you'll pay £1.80 for every additional gigabyte you use. The price can rack up quite quickly.
Now, this doesn't mean you should avoid data limited packages outright. For lighter users in smaller households they might be ideal. Just make sure you know how much data you will be using before you sign up.
How much data do you need?
The amount of data you use depends what you do online. Casual browsing, shopping and banking, email and Facebook are not especially data intensive. If that's the extent of your web use, and there's only a couple of people in your household, then you might be okay with a data limit.
Anything media-related, on the other hand, eats through data rapidly. Here's a rough guide to how much data common apps use:
- Netflix - the TV streaming service Netflix uses around 1GB of data per hour for standard definition, and 3GB per hour for HD. For BBC iPlayer, you can expect to use 2GB per hour of HD viewing.
- Sky TV on demand - On-demand downloads through your Sky box will also count towards your data allowance - even if you use Sky broadband. A typical movie will use 1.5GB of data for SD and 4GB for HD.
- Music streaming - The Spotify music streaming service uses around 115MB per hour at the highest quality setting.
- Gaming - Tests have shown that online video gaming can use anywhere between 20MB and 200MB, depending on the title. Stream your gameplay over the Twitch service and you'll use up to 1.6GB per hour.
- Video calls - Skype can use between around 200-600MB per hour for video calls, although it can be lower depending on the quality of the connection.
And then there are the numerous other things that will burn through a data allowance. Regular updates for your laptop, phone and games console, for example, stretch to several hundred megabytes or more. They may be mandatory, and they may even happen in the background without you realising.
Uploads count, too. use iCloud or OneDrive for your files, back up your important files to DropBox or Google Drive, share your holiday snaps on Facebook or Google Photos, or upload funny videos to YouTube or Snapchat, and that's another chunk of your data gone.
A false economy?
A cheap broadband deal with a monthly data allowance can be tempting - why pay any more than you need to, right? But it can prove to be a false economy, and you certainly shouldn't choose one in the hope that you'll be able to ration your usage.
Some providers, like BT, will start charging the moment you exceed your limit. Others, like Sky, will allow you to go over once every six months, before automatically upgrading your broadband to their more expensive Unlimited package. And in some cases, the difference between limited and unlimited isn't even all that great. At the time of writing you can get an unlimited fibre deal from Plusnet for just £25 more per year than Sky Fibre.
If you're only a light internet user, going online to pay bills and the like, then the cheapest, limited deal may suffice. For everyone else, you'd be better off steering clear and picking the best unlimited deal that suits your needs.
