If you spend any time online in the UK you have seen adverts promising that a VPN will keep you private and secure. Interest jumped after age checks under the Online Safety Act began on 25 July 2025. Ofcom figures reported by Tom’s Guide put daily VPN users at about 650,000 before the checks, above 1.4 million in mid-August 2025 and around 900,000 by November 2025. So do you actually need one? For many people the honest answer is sometimes, and this guide explains when.
What a VPN actually does
A virtual private network (VPN) creates an encrypted tunnel between your device and a server run by the VPN provider. Websites then see the provider server address instead of your home or mobile IP address, and anyone watching the network between you and that server, such as a public Wi-Fi owner or your internet provider, sees scrambled traffic rather than the sites you visit.
The catch is trust. A VPN does not remove the middleman, it swaps one for another. Your VPN provider can in principle see where your traffic goes, so the company you choose matters far more than the app badge.
What a VPN does not do
| Your worry | Does a VPN help? |
|---|---|
| Someone snooping on café, hotel or airport Wi-Fi | Yes, it encrypts your traffic on that network |
| Your internet provider seeing the sites you visit | Partly. It hides them from the provider, but the VPN company can see them instead |
| Phishing emails and fake websites | No. A VPN will not stop you typing a password into a fake page |
| Viruses and malware | No. You still need updates and security software |
| Sites that know who you are when you log in | No. Once you sign in, the site knows your account |
| A stolen or reused password | No. Use unique passwords and two-factor authentication |
| Internet speed | It can slow things down slightly because traffic takes a detour |
When a VPN is worth using
- Public Wi-Fi: cafés, hotels, trains and airports, where you do not control the network.
- Travelling abroad: to keep protection on unfamiliar networks. Check local rules first, because some countries restrict VPNs, and your bank may flag logins from unusual places.
- Working remotely: many employers provide their own VPN, which is separate from a consumer service and set up by your IT team.
- Limiting what your internet provider can log about your browsing, if that is your priority.
At home on your own broadband, most banking and shopping sites already use HTTPS encryption, which protects the content of your connection. For everyday home use a VPN adds less than simply keeping your devices updated and switching on two-factor authentication, which we explain in our two-factor authentication guide.
Is using a VPN legal in the UK?
Yes. Using a VPN is legal in the UK, and the government has said it will not ban them. After a consultation on children online safety, ministers decided in summer 2026 not to age-restrict or limit VPNs, according to reporting by TechRadar and the Internet Society. TechRadar noted on 4 November 2026 that the debate could return as the under-16 social media restrictions planned for March 2027 approach, so it is worth checking for updates.
Legal does not mean anything goes. Illegal activity stays illegal with or without a VPN, and some streaming, gaming and banking services restrict VPN use in their terms and conditions. Read those terms before relying on a VPN to reach a particular service. This is general information, not legal advice.
How to choose a trustworthy VPN
| What to check | Why it matters |
|---|---|
| Independent audit of the no-logs claim | Shows the promise has been tested by a third party |
| Clear company ownership and location | Tells you who holds your data and which laws apply |
| Modern protocols such as WireGuard or OpenVPN | Well-reviewed, secure ways to build the tunnel |
| A kill switch | Cuts the connection if the VPN drops, so traffic is not exposed |
| Honest pricing and a refund policy | Helps you avoid vague lifetime deals from unknown firms |
| Official app store listing | Reduces the risk of fake apps carrying malware |
Be careful with free VPNs. Running servers costs money, so a free service has to earn it somewhere, sometimes through adverts, tracking or selling data. If you want a free option, pick one from an established company with a clear privacy policy and understand its limits. We do not recommend or rank individual VPN brands here.

Setting one up in five steps
- Install the app only from your device’s official app store or the provider’s own website.
- Create the account with a strong, unique password and switch on two-factor authentication.
- Turn on the kill switch and the option to connect automatically on untrusted networks, if offered.
- Connect and check that pages load normally. Pause the VPN if your banking app complains.
- Keep the VPN app, your phone and your laptop updated.
A VPN is one layer, not a shield against everything. Scam adverts and cloned sites are still the biggest risk, so see our guide to spotting a fake website, and our steps for what to do after a data breach if an account is ever exposed.

Frequently asked questions
Is a VPN legal in the UK?
Yes. Using a VPN is legal, and the government decided in 2026 not to restrict them.
Does a VPN make me anonymous?
No. It hides your traffic from some observers, but your VPN provider, the accounts you log in to and your browser can still identify you.
Will a VPN slow my internet?
Often a little. Choosing a nearby server usually helps, and you can test with and without it.
Do I need a VPN on my phone?
It is most useful on public Wi-Fi. On your home network or mobile data, most apps already encrypt their traffic.
