What is the difference between a normal TV and a smart TV?
The core distinction comes down to internet connectivity. A smart TV is a traditional television set with integrated internet and interactive Web 2.0 features, according to Freely’s buying guide. A regular TV lacks internet connectivity and built-in apps entirely.
Key features of smart TVs
- Built-in apps and streaming services — no external box needed
- Direct access to Netflix, Amazon Prime Video, Disney+, and more
- Web browser for accessing online content
- Screen mirroring from smartphones and tablets
- Voice control via Alexa, Google Assistant, or proprietary assistants
- Regular firmware updates to add new features and apps
What traditional TVs lack
Traditional TVs require external devices to access streaming content. To watch catch-up TV or stream movies, you would need either a set-top box like a Sky Glass or Virgin TV Hub, or a streaming device such as a Amazon Fire TV Stick or Roku Express. Traditional TVs do not have built-in apps and cannot connect directly to streaming platforms, according to Aerial Services.
Smart TVs have built-in apps and streaming, but many still need an aerial connection for full Freeview live TV access. Just because a TV is “smart” does not mean it replaces your aerial — it adds internet features alongside traditional broadcast reception.
The implication: if you want every channel without paying for streaming subscriptions, a smart TV plus an aerial gives you both worlds. But for cord-cutters who only stream, a smart TV alone may suffice.
How does a smart TV work?
A smart TV connects to your home internet — via Wi-Fi or Ethernet cable — to access streaming platforms, apps, and online services. Samsung describes a smart TV as “an internet-enabled TV which connects to your favourite streaming platforms.” This means once connected, you can launch apps directly from your TV’s home screen without any additional hardware.
Internet connectivity process
- TV detects available Wi-Fi networks or accepts Ethernet cable connection
- User enters Wi-Fi password or network credentials
- TV connects to the manufacturer’s server to verify account and download app catalogue
- Apps are installed from the TV’s app store (similar to a smartphone)
- Streaming services may require individual account logins
Built-in apps and streaming
Most modern smart TVs come preloaded with popular streaming apps. Freely is increasingly built into new smart TVs alongside Netflix, Prime Video, and other services, TechRadar reports. The TV essentially functions as a computer monitor combined with a digital media player, integrating television, computer, and streaming device capabilities into one device.
Smart TV operating systems vary by manufacturer — some use Android TV, others use proprietary systems like Samsung’s Tizen or LG’s webOS. This affects which apps are available and how smoothly they run. When buying, check that your preferred streaming services are supported on your chosen platform.
What this means: the smart TV experience depends heavily on the operating system. A TV with a poor app store or slow processor may frustrate you more than a regular TV with a dedicated streaming stick attached.
Does a smart TV need internet or Wi-Fi?
Yes and no. Smart TVs require internet to access their smart features — streaming apps, web browsing, and firmware updates. However, they can still function as regular televisions for live broadcasts without an internet connection, provided you connect an aerial or cable service.
Smart features dependency
Freely requires Wi-Fi for its core channels from BBC, ITV, Channel 4, and Channel 5, according to Freely’s official guidance. Other smart TV functions — accessing apps, streaming on-demand content, using voice assistants — all depend on an active internet connection. If your Wi-Fi goes down, so do these features.
Offline functionality
- Watch live TV via connected aerial (standard Freeview channels)
- Play content from connected USB drives or external hard disks
- Use HDMI inputs for gaming consoles, Blu-ray players, or cable boxes
- Access saved recordings (if TV has recording capability)
Without internet, a smart TV is functionally identical to a regular TV — you lose app access, streaming, firmware updates, and any cloud-based features. Before buying, consider whether reliable broadband is available in your home, as the smart features become expensive decoration otherwise.
The pattern: smart TVs are designed for connected homes. If your broadband is unreliable or you live in an area with limited connectivity, a regular TV with a streaming stick might be more practical — the stick can be replaced if it fails, whereas a TV cannot.
What channels do you get on a smart TV for free?
This is where things get particularly relevant for UK viewers. Smart TVs can access several free TV options, including the new Freely platform and the established Freeview service.
Freely service details
Freely is a free streaming platform for live TV and on-demand content backed by BBC, ITV, Channel 4, and Channel 5. It streams over broadband without needing an aerial or dish, Manhattan TV explains. The service launched in April 2024, offering 70 live TV channels and over 75,000 hours of on-demand content, Which? confirms. By 2026, Freely supports more than 55 channels.
Other free options
- Freeview: The established UK platform using TV aerial, operational for over 20 years, guaranteed until at least 2034. Offers more channels than Freely Wi-Fi only.
- Freeview Play: Adds catch-up apps and on-demand when connected to broadband.
- Freesat: Satellite-based alternative for areas with poor aerial reception.
- Individual catch-up apps: BBC iPlayer, ITV Hub, Channel 4, and My5 are all free to download on most smart TVs.
The implication: smart TV owners in the UK have multiple free TV pathways. Freely is the newest option and ideal for broadband-only households, while Freeview remains the most comprehensive for those with aerials installed.
What is the downside of a smart TV?
Smart TVs offer convenience, but they come with trade-offs that are worth considering before you buy. Understanding the limitations helps you decide whether a smart TV’s extra cost is justified for your viewing habits.
Common limitations
- Software slowdowns: Like any computer, smart TVs can become sluggish over time as apps accumulate and firmware ages. Budget models are particularly susceptible.
- Privacy concerns: Smart TVs collect data on viewing habits and may share information with third parties. LG has faced scrutiny over data collection practices, according to industry reports.
- Obsolescence risk: Smart TV platforms evolve rapidly. A TV purchased today may not support new apps in five years, while a regular TV continues working indefinitely.
- Interface complexity: Smart menus and app interfaces can be slower to navigate than simply pressing a channel button on a regular remote.
Performance issues
Cheaper smart TVs often use lower-powered processors designed to reduce costs, not maximize speed. Apps may load slowly, buffering during streams, or the TV interface may stutter when switching between apps. TechRadar notes that Freely is built into future smart TVs alongside Netflix and Prime Video, but the experience quality depends on hardware specifications.
Smart TVs can suffer from planned obsolescence as manufacturers phase out software support. If you buy a budget model with a proprietary OS, check the manufacturer’s support history — some brands abandon software updates within three to four years.
What this means: for viewers who primarily watch live TV via aerial and rarely use streaming apps, a smart TV may offer more complexity than benefit. The extra cost and privacy implications only make sense if you actively use the connected features.
Upsides
- All-in-one entertainment with no additional streaming devices
- Direct access to popular streaming services and apps
- Freely support for aerial-free free TV in the UK
- Screen mirroring from smartphones and tablets
- Voice control and smart home integration
Downsides
- Potential privacy data collection concerns
- Software slowdowns on budget models over time
- Obsolescence risk as platforms evolve
- Higher upfront cost than regular TVs
- Interface can be slower than dedicated streaming devices
Freely is praised for eliminating the need for an aerial but offers fewer channels compared to Freeview, Which? notes. For cord-cutters who stream everything, a smart TV simplifies setup. For traditional broadcast viewers who want maximum channel choice, Freeview via aerial remains the stronger option.
A smart TV is an internet-enabled TV which connects to your favourite streaming platforms.

Frequently asked questions
How can I tell if my TV is a smart TV?
Check the TV’s menu system — if you see app icons for Netflix, Amazon Prime, or BBC iPlayer on the home screen, it is a smart TV. You can also look for Wi-Fi or Ethernet connection options in the network settings. Most manufacturers label “Smart TV” or include “Wi-Fi” in the model name on the box.
Can you watch normal TV channels on a smart TV?
Yes. Smart TVs support traditional broadcast television through a connected aerial or cable service. You can scan for Freeview channels just as you would on a regular TV, according to Aerial Services. The smart features add streaming capabilities alongside traditional channels rather than replacing them.
Can I just plug in a smart TV?
For basic TV watching, yes — connect the aerial cable and power, then scan for channels. However, to use smart features, you need to connect to your home Wi-Fi or Ethernet network and set up your streaming service accounts. The initial setup takes 15-30 minutes depending on your broadband speed and the number of apps you want to configure.
What is Freely, and can I get it on my TV?
Freely is a free streaming platform for live TV and on-demand content backed by BBC, ITV, Channel 4, and Channel 5, TechRadar explains. It is available on TVs with Freely built-in or compatible set-top boxes, but not on existing TVs without compatibility. The service launched in April 2024 and requires no aerial — only broadband with a minimum 10 Mbps speed, Which? confirms.
What does a Smart TV do that a regular TV doesn’t?
A smart TV can connect to the internet for streaming apps, web browsing, and interactive services without any external devices. It integrates television, computer, and streaming device capabilities into one unit. A regular TV requires external boxes or streaming sticks to access online content, Freely’s guide clarifies.
How to tell if a TV is a smart TV without turning it on?
Look for Wi-Fi logos, “Smart TV,” or “Android TV” labels on the box or product description. Check the specifications list for network connectivity options like Wi-Fi, Ethernet, or Bluetooth. The model name often hints — Samsung uses “AU” or “QLED” prefixes for smart models, LG includes “webOS” indicators, and Sony mentions “Android TV” or “Google TV.”
What is a smart TV app?
A smart TV app is software designed to run on your television’s operating system, similar to smartphone apps. Examples include Netflix, BBC iPlayer, Spotify, and YouTube. These apps are accessed through the TV’s built-in interface and let you stream content directly without external devices. App availability varies by TV brand and operating system.
