This post was originally published in 2017, when Discovery announced plans to launch a second free-to-air channel in the UK. At the time, the details were limited. We now know that the channel was Quest Red, which launched on 15 March 2017 and became part of Discovery’s growing free-to-air presence alongside Quest.
Quest Red is still available today and is now part of Warner Bros. Discovery’s wider UK free-to-air channel line-up. The channel has moved on from being a new launch announcement and is now an established part of the free TV landscape, sitting alongside channels such as Quest, DMAX, Food Network, Really and TLC.
What Was Discovery’s Second Free-To-Air Channel?
The second free-to-air channel announced by Discovery was Quest Red. When the original news broke, Discovery had already built a strong free-to-air presence with Quest, which was available through Freeview as well as other TV platforms. Quest Red was introduced as a sister channel, with a different style of programming and a stronger focus on real-life stories, true crime, documentaries and factual entertainment.
At launch, Quest Red gave Discovery another route into homes that did not rely on paid TV subscriptions. That was important because Freeview remained one of the easiest ways for UK households to access extra channels without paying monthly TV package fees. For viewers, it meant more choice through a standard TV aerial setup, provided the property had suitable reception and the television or set-top box was tuned correctly.
Is Quest Red Still On Freeview?
Yes, Quest Red is still listed on Freeview. Freeview currently shows Quest Red on channel 40, although channel numbers can change over time when Freeview updates its line-up. If Quest Red is missing from your TV, the first step is usually to retune your television or Freeview box. In many cases, a simple retune will restore missing channels if the aerial signal is strong enough and the equipment is working correctly.
If a retune does not bring the channel back, the problem may be linked to reception, aerial position, cabling, a damaged aerial, a weak signal, interference or an issue with the TV itself. Some channels are also carried on different multiplexes, so it is possible to receive some Freeview channels while others are missing. That is why a missing channel does not always mean Freeview has stopped working completely.
Quest, Quest Red And Warner Bros. Discovery’s Free-To-Air Channels
Discovery has changed significantly since the original announcement. The company is now part of Warner Bros. Discovery, and its UK free-to-air channel portfolio has grown. In 2026, Warner Bros. Discovery refreshed its free-to-air offering, with channels including Quest, Quest Red, Food Network, Really, DMAX and TLC.
Quest remains focused on hands-on entertainment, restoration, motoring, antiques and factual entertainment. Quest Red has developed more strongly around true crime and real-life mystery programming. TLC has also become free-to-air in the UK, giving viewers access to a broader entertainment schedule without needing a subscription TV package.
Why Free-To-Air Channels Still Matter
Streaming has changed how people watch TV, but free-to-air television still matters for millions of homes. Freeview gives viewers access to a wide range of channels without a monthly subscription, and for many households it remains the simplest way to watch live TV. You only need a suitable TV aerial, a compatible television or box, and a decent signal at the property.
That is why channel launches and Freeview updates still matter. When broadcasters add, remove, rename or move channels, viewers may need to retune their TV. Sometimes the change is straightforward. Other times, the update reveals an existing aerial or signal problem that had gone unnoticed because the main channels were still working.
What To Do If Quest Red Or Other Freeview Channels Are Missing
If Quest Red, Quest or other Freeview channels are missing, start with a full retune. Most TVs have this option under settings, channel setup, broadcasting or installation. A full retune clears the old channel list and searches again for the latest Freeview services available in your area.
If the channel is still missing after retuning, check whether other channels are affected. If only one or two channels are missing, it may be a multiplex or tuning issue. If many channels are breaking up, freezing or disappearing, the problem is more likely to be linked to signal strength, aerial alignment, cabling, connectors or local reception conditions.
Common signs of a Freeview reception problem include:
- Channels disappearing after a retune
- Picture freezing or breaking into blocks
- Sound cutting in and out
- Some channels working while others are missing
- Reception becoming worse in bad weather
- Signal problems affecting one room but not another
Do You Need A New Aerial To Watch Quest Red?
Not usually. If your current aerial is in good condition and receives the correct Freeview signal for your area, you should not need a new aerial just to watch Quest Red. However, if your aerial is old, damaged, badly aligned or connected with poor cabling, you may struggle to receive the full Freeview channel list.
Some homes also have aerials that were installed years ago and have never been checked since. Over time, brackets can move, cables can degrade, water can get into connections, and signal levels can change. If your TV has started losing channels or breaking up, the aerial system may need testing rather than replacing immediately.
When To Book A TV Aerial Engineer
If retuning does not fix the issue, it may be time to book a professional signal check. A qualified engineer can test the signal at the aerial, the cable, the wall plate and the TV point. That helps identify whether the problem is caused by the aerial itself, poor cabling, a weak signal, a faulty amplifier, water damage or an issue inside the property.
WeFitAerials can help with TV aerial installation if your current setup is not suitable, and we can also help with aerial repairs if the existing system can be fixed. In many cases, a repair, realignment or cable replacement is enough to restore reliable Freeview reception without needing a completely new setup.
Final Thoughts
The 2017 announcement about Discovery’s second free-to-air channel has now become part of a much bigger story. Quest Red launched as Discovery’s second free-to-air UK channel, and it remains available today as part of Warner Bros. Discovery’s wider free TV line-up. For viewers, the key point is simple: if your aerial system is working properly, channels such as Quest Red should be available through Freeview in supported areas.
If you are missing Quest Red, Quest or other Freeview channels, try retuning first. If that does not solve the problem, the issue may be with your aerial, cabling or signal quality. A professional check can quickly show whether you need a repair, an upgrade or a new aerial installation.
