Best BT deals: The best offers on BT broadband and TV, as well as mobile and SIM-only deals, this January

Here's a list of all the best BT deals and offers for new and existing customers in the UK this January
BT is the largest provider of fixed-line, broadband and mobile services in the UK. The company provides multiple services but because of its immense popularity, it may be a challenge to find the best BT deals depending on the service that you're looking for. To help you stay on top of all BT deals (including broadband, TV, mobile and SIM-only offers), we've listed the best ones this month below.
We'll list the best deals in each category one by one. You'll often find that deals get better the longer you're willing to commit for. Of course, this also means that you should do your due diligence and check the contract fine print. Usually, you'll get what is promised, but breaking a contract could result in an early exit fee so it's worth keeping this in mind.

Get the best BT broadband deals this January
Before detailing the different BT broadband deals, we'll first dissect the service so that you know what you're getting into and whether or not it's worth your money. This will also help you compare BT's deals with other broadband service providers to let you know whether you're getting a good deal or not.
As you can see from the below table, BT broadband is divided into three plans that increasingly offer better speeds but cost more. It's worth noting that all of the plans bind you to a 24-month contract and have unlimited data. BT's Stay Fast Guarantee is basically the minimum speed you're guaranteed to get on the plan, regardless of your connection.
Before selecting a plan, it's a good idea to know approximately how much speed you actually need. This can depend on a few factors, including what you mainly use the internet for and how many people live in your household. It's better to choose one of the faster plans if there are a lot of people using the internet on multiple devices in your household.
Similarly, if you like watching movies in UHD resolution or streaming live sporting events, you should go in for a faster plan such as BT Fibre 2 to avoid quality or lagging issues while streaming. This rule also applies if you play video games on your PlayStation or Xbox because they're notorious for the amount of bandwidth they take up.
Contrastingly, if you live alone and only use the internet for work and watching movies in your free time, the BT Fibre Essential plan could be perfect for you. Not only will you be saving money in the long run, but the speeds are more than enough for anything you need, including watching videos on your TV and mobile and uploading work files.

BT broadband and TV
TV services in the UK are expensive by their very nature and everyone knows that BT, Sky and Virgin are the three premium TV offerings, giving you access to a wide range of content via a slick interface and remote. The great news if you're signing up to BT is that you can often get a cheaper deal if you combine your broadband and TV package compared to if you were to choose one service individually.
You'll incur setup fees if you're a new customer, but if you're looking to stay with BT for a while then you'll find that it has a wide range of content to suit your tastes, making it worth every penny. Like Sky, BT has some of its own programmes, but if you want one, it doesn't necessarily mean that you have to sacrifice the other. BT offers Sky TV programming via neat add-ons that you can bolt onto your package.

BT Mobile
BT Mobile offers a range of deal and non-deal offerings on multiple devices, ranging from mobile phones to tablets. The deals you'll find will often alternate from one phone to another, but the good news is that there's always one of the latest handsets on discount. Again, these deals come at a price: you'll need to sign up for a longer-term contract in advance and breaching this could result in a fee.
The best BT Mobile deals and offers this January
1. Doro 8050 (£22/mth with 15GB of data)
Do you have an elderly relative who struggles with smartphones? If so, the Doro 8050 could be just the ticket: it's very easy to use and even features a dedicated Response button that sends an alert to a family member. This deal is for the version in black with 15GB of data and 16GB of storage on a two-year contract. There's no upfront cost and, if you're already a BT customer the monthly cost will drop to just £17.
2. Samsung Galaxy A12 (£22/mth with 15GB of data)
If you're after a budget phone that can see you through a busy day, you've come to the right place: the Samsung Galaxy A12 lasted a gargantuan 15hrs 58mins in our video-rundown test. BT is giving you the chance to make the most of that stamina, along with 15GB of data and 64GB of internal storage, for just £22 per month on a two-year contract. And, if you're already a BT customer, that will drop to a stunning £17 per month.
3. Apple iPhone SE (£33/mth with 15GB of data)
BT is offering an eye-catching deal for the iPhone SE, which we crowned the “best value iPhone” in our original review. For £33 per month for two years, you get the 64GB version of the phone, as well as 15GB of data, unlimited texts and unlimited minutes. And, if you've already taken advantage of one of the BT broadband deals above, the price drops to a bargain £28/mth. If that wasn't enough, BT is also throwing in three months of Apple TV+ for free.
4. Samsung Galaxy S20 FE 4G (£45/mth with 15GB of data)

This deal gets you the 128GB model in a choice of three colours, as well as 15GB of data, for £45 per year for two years. And, if you're already a BT customer, that will drop to £40 per month. 
BT SIM-only deals
BT also has SIM-only deals, starting from 5GB (£13/mth) to 100GB (£25/mth) on a 24-month plan. Again, you'll notice a general trend that deals tend to get better if you're willing to go in for a larger data plan. We've often noticed that you get the most bang for your buck somewhere in the middle of these extreme data and price points. Many of the higher data packages also include a sweet additional extra, which is usually a free subscription to the BT Sport app on your device.
All BT SIM-only deals come with the following features as default:
- 30-day moneyback guarantee
- Retain your existing phone number
- Unlimited minutes and texts
- 4G and 5G (phone-dependant) enabled
- Access to five million BT Wi-Fi hotspots
- Free-roaming in 47 countries
- Increase or decrease data each month
