18-month broadband deals September 2021

They aren’t too long, and they aren’t too expensive: 18-month broadband deals hit that sweet spot. Let’s take a look at what you can expect from an 18-month contract, and how to find the best one for your household.

What is an 18-month broadband contract?

All broadband deals have minimum contract terms – the minimum length of time that you’re required to pay for that package. It can range from 30 days up to two years, depending on the provider and the deal.

Longer-term contracts are often cheaper per month – and can mean you lock in a low price for the whole of that contract length.

Shorter-term contracts, on the other hand, tend to be more costly overall but give you more flexibility. They’re better if you may be moving house next year, or simply aren’t dead set on sticking with the provider for a long time.

Given all that, you may have found that an 18-month broadband deal is the sweet spot for you: not too expensive, not too long-term.

Once your 18 months are up, you’re free to switch without penalty – or stick around on a renewed deal or one-month rolling basis, if you prefer.

18-month broadband and TV deals

Want a telly package as well? You can get a broadband and TV bundle on an 18-month contract too.

Sky and Virgin Media both offer their TV packages on an 18-month contract basis, so you have the pick of the best.

TalkTalk will let you add a TV box onto your 18-month broadband deal too, but bear in mind it doesn’t give you nearly as many extra channels and features.

What are my other options?

24-month contracts are available from providers such as BT, EE, Vodafone, and Zen. You’ll often get a better value broadband deal if you’re willing to sign up for a longer period. Because many providers raise monthly costs when your minimum contract terms ends, this is the best way to lock in a low price for the longest time. The downside is that you have less flexibility – if you need to cancel early, you could be hit by hefty early-termination fees.

12-month contracts lock you in for a shorter time, meaning more flexibility – and if you’re renting, it’ll likely match up with the timing of your rental agreement. They’re rarer, however. Right now, providers offering 12-month broadband deals include Now, Plusnet, and John Lewis. Compare 12-month broadband contracts here.

1-month rolling contracts are the most flexible of all, and a good choice if you know you’re moving house in a few months’ time. Bear in mind these are usually more expensive per month, often with higher upfront costs too – and you won’t get much choice over providers. They’re currently offered by Now, Hyperoptic, and various mobile broadband networks. Compare no-contract broadband here.
