  • What is Openreach?

    Openreach is the company that maintains the former British Telecom Network used for the majority of broadband and phone services. If a repair or installation is required, it’s Openreach who will send an engineer, not your provider.

    More than 650 service providers using the Openreach network. That’s the majority of the UK’s broadband providers. This includes Sky, TalkTalk and BT. The exception to this is Virgin Media - it uses its own, separate cable network.

At least 90% of Portsmouth properties can expect to find a Virgin deal

Thanks to a partnership between City Fibre and Giganet, there's full fibre broadband in Portsmouth, albeit with limited availability. For Portsmouth North premises, the "altnet" accessibility to FTTP providers is over 73%. If you can get it, this can offer ultrafast speeds of 1Gb+ and provides a competitive alternative option over Openreach and Virgin.

When searching for a broadband package, you can add your address into our deals checker to narrow down the options by location. This will use data from your closest exchange to list only deals which should be available to your home.

Why do we need your address?

We need your address to show you the broadband deals available at your home. This information is gathered in partnership with thinkbroadband.
Read our privacy policy for more details.

Sort by

Our deals are sorted by how popular they are with our visitors. The more people clicking on a deal - especially if they then buy it - the higher it is in our tables.

Sponsored deals are not factored in when sorting by popularity.

Pricing Calculation

Effective monthly cost = This shows how much you are effectively paying each month over the length of the contract by taking into account rewards savings and one-off fees. The calculation for this is monthly cost x length of contract + setup cost - rewards savings.

Monthly cost = What you'll pay each month. This does not include additional fees, such as phone calls, which may be added to your bill.

Setup cost = The cost of installation, postage for the Wi-Fi router, and any other one-off charges.

Total Price Rise Costs = This is the additional amount paid over the course of the contract based on any annual price rises by the provider.

Rewards saving = The value of vouchers and other perks included with a deal such as cashback, bill credit or a gift card which you can claim.

What does this mean?

The speedometer gives you a quick idea of how fast a deal is. Speeds are shown in average download speed (Mb/Gb) – here’s what each level means:

💡 Tip: You don’t always need the highest speed, but it can help make things smoother and future-proof your home.

What is a trending deal?

A trending deal is a package that has increased in popularity in recent days. We base this on the number of people clicking on, and buying the deal.
