What broadband speed is right for me?

The first thing you need to decide when shopping for broadband is the right kind of package.

Broadband providers will either offer standard, superfast or ultrafast 'fibre' broadband, and often it can be difficult to figure out which one you need.

On the one hand, you do not want to be overpaying for speeds that you don't need, but on the other you do not want too low a speed so that your internet connection does not function properly.

Our quiz below takes all the guesswork out of figuring out what speed is right for you and gives you a result based on how you use the internet.

Best standard broadband deals 

These deals typically have an average speed of 10-11Mbps (megabits per second) and are suited for people who do not have many internet-enabled devices and/or who do not use the internet frequently. These speeds should still be fine for browsing or light streaming on services such as Netflix or BBC iPlayer.

Sky Broadband Unlimited

  • Average Speed: 11Mbps
  • Contract Length: 12 months 
  • Price: £18 per month 
  • Upfront costs: £9.95 

    Total cost over contract: £225.95 
    Effective cost per month: £18.83 

The TV juggernaut is currently offering one of the cheapest standard broadband packages around at the moment, with unlimited downloads and a home phone for just £18 a month. 

This deal is made sweeter by the current offer of a Mastercard Prepaid Card with £50 credit on it, allowing you to spend the money anywhere you wish.

As standard, Sky Broadband customers also receive a 12-month trial of McAfee's Internet Security package and unlimited access to Sky Talk Shield, which screens calls and allows you to block persistent spam callers.

Plusnet Unlimited

  • Average Speed: 10Mbps
  • Contract Length: 12 months
  • Price: £18.99 per month
  • Upfront costs: £0

Total cost over contract: £225.95
Effective cost per month: £18.99

Plusnet is regularly known to have competitive broadband deals and this is no exception.

For £18.99, customers get unlimited usage, a free wireless router and a UK-based call centre. Plusnet's package ties you down for only 12 months, which is great for those who are not looking for a long-term commitment.

Currently, Plusnet is also offering a £50 Amazon.co.uk gift card to new customers who sign up before the 7th August.

Best superfast broadband deals 

These deals typically have average speeds ranging from 35 to 67Mbps and are suited for people who share their connection with others and/or who frequently use the internet, whether you browse all the time or stream a lot of on-demand content.

Vodafone Superfast 1

  • Average Speed: 35Mbps
  • Contract Length: 18 months
  • Price: £25 per month
  • Upfront costs: £9.99

Total cost over contract: £459.99
Effective cost per month: £25.56

Although Vodafone has only been offering broadband packages since 2015, its prices have become increasingly competitive, with one of the cheapest fibre packages currently available at £25 per month.

Existing Vodafone mobile customers receive a £1 discount, making the price £24 per month.

If you sign up or switch before the 3rd of September, Vodafone is offering one of four tech gifts, with values going up to £199.

Vodafone also has an ultimate speed guarantee via the Vodafone Broadband app, so if your speed drops below 25Mbps at any time, you can claim a 15% discount on that month's bill.

Sky Fibre Max

  • Average Speed: 63Mbps
  • Contract Length: 18 months
  • Price: £30 per month
  • Upfront costs: £9.95
    Total cost over contract: £549.95
    Effective cost per month: £30.55

Similar to its standard package, Sky Fibre Max is also extremely competitive in terms of price, offering unlimited usage and an average speed of 63Mbps for just £30 per month. 

As with standard packages, Sky customers are also receiving a £50 Mastercard prepaid card when they sign up.

Best ultrafast broadband deals 

These deals are for the heavy internet user and/or very large families, who need lots of bandwidth in order for everyone to be satisfied. If you have kids who love gaming or you're set on watching Netflix or BBC iPlayer unless in 4K, ultrafast is for you.

Virgin Media VIVID 100

  • Average Speed: 108Mbps
  • Contract Length: 12 months
  • Price: £32 per month
  • Upfront costs: £0

Total cost over contract: £384
Effective cost per month: £32

Virgin Media is well established as a broadband provider, although it may not be the first one you think of if you want a cheap broadband deal.

The cable-only broadband provider has recently slashed prices and has also got rid of setup costs to entice customers, so now is a good time to check out its deals.

Also, Virgin Media is offering Talk Weekends at no extra cost, which allows you to call UK landlines (01, 02 and 03 numbers) and 0845/0870 numbers (Virgin Media defines the weekend as all day Saturday and Sunday).

While this deal is very good, one thing to keep on top of is that after the contract ends, the price jumps up to £47 – that's a 47% price increase.

Virgin Media VIVID 350

  • Average Speed: 362Mbps
  • Contract Length: 12 months 
  • Price: £42 per month
  • Upfront costs: £0

Total cost over contract: £504
Effective cost per month: £42

Although some may balk at the £42 a month asking price, this deal is still worth mentioning as it offers the fastest speed currently widely available for a price lower than some providers’ superfast fibre speed deals.

In fact, the price has actually dropped since we first featured it last month, as Virgin attempts to entice more broadband customers to sign up. 

As with VIVID 100, Virgin Media is offering Talk Weekends at no extra cost, which allows you to call UK landlines (01, 02 and 03 numbers) and 0845/0870 numbers (Virgin Media defines the weekend as all day Saturday and Sunday).

Thinking of switching provider? It doesn’t need to be difficult. We asked almost 1,000 switchers how they found it, and 77% agree the process was easy. Read our guide on how to switch your broadband provider for essential help and advice.

What else should I consider when buying broadband?

I rarely use my home phone (landline) – can I save money on a broadband-only deal?

Many broadband-only deals still require you to also have line rental with the provider or from elsewhere. Often, it is cheaper to buy both from the same place rather than sourcing line rental with another provider.

However, other plans (such as Vodafone’s Superfast plans) also come with no cost for line rental and a landline, using a pay-as-you-go model for calls by charging a price per minute. As long as you don't plan to use your home phone much, these plans may appeal to you as a way to save money by not paying for a landline you don't use.

Do I need unlimited broadband?

The question of whether to get a limited or unlimited package is far less important than it used to be.

Limited broadband packages would set a fair-usage policy or ‘cap’, which if exceeded may have resulted in additional charges, a slowed-down internet connection or no connection at all. The benefit of these limited deals is that they would usually be cheaper.

Most modern packages are unlimited, which means you don’t have to worry how much data you use. If you do encounter a limited data deal, think carefully about whether this will be enough to get you through the month, and check to see what happens if you exceed it.

Is unlimited broadband truly unlimited?

Fair-usage caps (a set amount of monthly data that if exceeded may result in you being charged) used to be fairly common, essentially turning ‘unlimited’ plans into limited plans with a high data cap.

Today, most providers offer a truly unlimited service, but some smaller providers do still have traffic management policies in place. These slow down certain kinds of internet activities that require a lot of bandwidth once you hit a preset limit.

For example, some providers slow down the speed of certain internet activities (such as peer-to-peer downloads) in order for other activities which are time-sensitive (such as online gaming and video calls) to not be interrupted.

It’s always worth checking whether any speed-limiting or traffic management takes place if you’re considering switching provider.

Are there any upfront or hidden costs?

Broadband plans often come with upfront costs, which can take various forms. Common examples include paying for a router to be delivered, set-up fees, connection charges and new line fees. You might also be expected to pay an upfront fee for a PVR (set-top box) if a TV package is included, which may or may not be optional. It is important to factor in these costs when deciding what broadband deal is right for you. Our reviews include an ‘effective cost’ for this reason.

You might also want to consider the telephone package. If you’re used to free evening and weekend or free anytime calls and want to keep these benefits, chances are you’ll be paying extra on top of the advertised fee on a new broadband package.

What contract length is right for me?

Contract lengths are also an important consideration. Some deals might seem cheaper on the surface, offering lower monthly prices. But long contract terms mean that you may end up paying more than you wanted to over that period of time. Conversely, some providers have price guarantees, and a longer contract can offer reassurance that this won’t go up until it expires.

Our deals include the total cost over contract, and the effective cost per month.

What if I’m still in a contract with my provider and want to switch?

If you’re still in contract with your provider, you may have to pay off the remainder of your contract if you leave.

However, Ofcom rules state that if you experience price increases mid-contract, you have 30 days from when you are officially notified of the increase when you can switch without paying a penalty. Read more about your rights if a broadband provider increases prices.

In some circumstances, such as when you’re coming to the end of a contract and see a particularly good limited-time offer elsewhere, it might be worth paying off the contract. You might also consider this if the service you’re getting is poor, and you feel you might get a better service with a different provider.

But generally it’s a good idea to wait until your contract expires before you consider moving. It’s important to know exactly when this will be, since in many cases your monthly cost will rise when your contract expires, so you may be paying more than you need to.

In these situations you could switch, or haggle. In the latter case, information such as the deals we’ve listed above can be very useful, since rival prices are great ammunition to try and get a discount. Read our guide on how to haggle for the best broadband deal
