A few years ago I started looking into VPNs properly after a conversation with a neighbour who works in cybersecurity. He was not alarmist about it, but he made one point that stuck with me: the data about your browsing habits that advertisers and data brokers collect is persistent, cumulative, and essentially permanent. Once it is out there, it is out there.
That is not a reason to panic. But it is a reason to understand what a VPN does, decide whether it is useful for your household, and set one up properly if you decide it is. This guide does all three.
What a VPN Actually Does (In Plain English)
A VPN, or Virtual Private Network, does two main things.
First, it encrypts your internet connection. This means that anyone who might be able to see your internet traffic, such as your broadband provider, the owner of a public Wi-Fi network, or certain kinds of network monitoring software, cannot read what you are doing. They can see that you are connected somewhere, but not what you are looking at or sending.
Second, it masks your IP address. Your IP address is a number that identifies your connection on the internet. It reveals your approximate location and is used by advertisers, streaming services, and websites to track your activity across the web. When you use a VPN, websites and services see the VPN server’s IP address instead of yours.
What a VPN does not do: it does not make you completely anonymous online. If you are logged into Google or Facebook, those services still know who you are. A VPN is one layer of privacy, not a complete solution. It also slightly reduces your internet speed, though on a good VPN the difference is barely noticeable for everyday use.
Do Families Actually Need a VPN?
The honest answer is: it depends on how you use the internet and what level of privacy matters to you.
A VPN is genuinely useful in several specific situations. If anyone in your household regularly uses public Wi-Fi (in coffee shops, hotels, airports, or school), a VPN significantly reduces the risk of your connection being monitored or intercepted. If you have concerns about your broadband provider selling data about your browsing habits (legal in various ways in both the UK and US), a VPN prevents that. If you or your kids use services that vary in availability by region, a VPN lets you connect through a server in another country.
For general home use on a private network, the privacy benefit is lower but still present. Many families use a VPN primarily to protect devices when they are away from home.
Choosing a VPN: What to Look For
Not all VPNs are created equal. There are hundreds of options, including some that are actively harmful. Here is what matters.
No-logs policy. A trustworthy VPN does not store records of what you do on it. Look for a VPN that has had its no-logs policy independently audited. Mullvad, ProtonVPN, and ExpressVPN are examples that have published third-party audits.
Jurisdiction. VPN providers based in countries with strong privacy laws offer better legal protection. Switzerland (ProtonVPN) and British Virgin Islands (ExpressVPN) are considered good. Avoid free VPNs based in countries with aggressive data sharing laws.
Speed and server coverage. More servers in more countries means better connection quality and more flexibility. For a family, you want a VPN that handles multiple simultaneous connections without slowing things down.
Free vs paid. Free VPNs are almost always a bad idea. They typically make money by selling your data, which is the opposite of what you are trying to achieve. A good paid VPN costs around £3 to £8 a month. ProtonVPN is an exception, offering a genuinely good free tier with unlimited data, though on fewer servers.
Our recommendation for families is NordVPN or ProtonVPN. Both have clean privacy records, good speeds, easy apps, and reasonable family plans.
Setting Up a VPN on Windows
Download the VPN’s app from their website. Install it and sign in with your account credentials. Once open, you will see a map or server list. Click Connect (most apps connect to the best available server automatically). A notification or icon change confirms you are connected.
To check it is working, go to whatismyipaddress.com before and after connecting. Your IP address and shown location should change.
To disconnect, open the app and click Disconnect. Most apps also have an option to launch automatically at startup and auto-connect when you join unfamiliar networks.
Setting Up a VPN on Mac
The process is identical to Windows. Download the VPN’s Mac app from their website, install it, sign in, and connect. The app lives in your menu bar for quick access. Check ip address before and after to confirm it is working.
Setting Up a VPN on iPhone and iPad
Go to the App Store and search for your VPN provider’s app (NordVPN, ProtonVPN, etc.). Install it, sign in, and tap Connect. iOS will ask for permission to configure a VPN profile on your device. Tap Allow. Once connected, a small VPN label appears in your status bar.
Setting Up a VPN on Android
Go to the Google Play Store and install your VPN provider’s app. Sign in and tap Connect. Android will prompt you to approve the VPN configuration. Tap OK. Look for the key icon in your status bar to confirm it is connected.
Setting Up a VPN on Your Router
If you want every device in your home protected, including smart TVs, game consoles, and IoT devices that cannot run a VPN app themselves, you can configure a VPN directly on your router.
Not all routers support this. You need a router that supports OpenVPN or WireGuard protocols. Many consumer routers from brands like Asus, Netgear Nighthawk, and GL.iNet support this out of the box or via custom firmware.
The setup process varies by router model. Your VPN provider’s website will usually have a specific guide for common router types. The broad steps are: log into your router’s admin panel, find the VPN client section, enter your VPN provider’s server details and credentials, and connect.
Once set up, every device on your home network is automatically routed through the VPN without needing an app.
The Legal Position in the UK
Using a VPN is entirely legal in the UK. There is no restriction on using a VPN for privacy or security purposes. The only caveats apply to things that are illegal regardless of whether you use a VPN: using it to commit crimes, access illegal content, or circumvent court-ordered blocks in ways that break UK law. For normal family use, there is nothing to worry about.
Common Problems and Fixes
My internet is much slower with the VPN on. Try connecting to a server geographically closer to you. Also try changing the VPN protocol in the app settings. WireGuard is generally faster than OpenVPN. If a particular server is congested, switching to a different one in the same country helps.
Some websites are not loading. Some services actively block VPN traffic. Streaming services particularly do this. Try a different server location or check your VPN provider’s dedicated streaming servers if they have them.
The VPN keeps disconnecting. Check your app has a kill switch enabled. A kill switch cuts your internet if the VPN drops, which prevents your real IP being briefly exposed. Also check your device’s power management settings are not killing the VPN app in the background.
The Family Angle
For teenagers especially, using a VPN on their phone when they are out and about, connecting to school, library, or cafe Wi-Fi, is a straightforward security improvement worth making. Public networks are the most common place for the kind of passive data collection and occasional active snooping that a VPN protects against.
Setting up a VPN on the family router means you do not have to manage individual devices. One configuration protects everything.
For parents who work from home and handle sensitive work data on a home network, the combination of a good router-level VPN and strong Wi-Fi passwords is a reasonable baseline security setup.
The conversation to have with kids is simple: explain that a VPN is like putting your internet connection in a sealed envelope before it leaves the house, so anyone who sees it passing by cannot read what is inside. That framing tends to make sense immediately.
