Home broadband deals in Portsmouth

Portsmouth residents have access to a good variety of fixed-line home broadband services, giving them plenty of choice when it comes to selecting a broadband package.

Almost everyone can sign up to a superfast standard fibre service with speeds up to 30Mb. But there's also scope to sign up to an ultrafast, full fibre deal if you need more speed.

  • 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.

Virgin fibre has the fastest mass-market service available, currently topping out at a rapid 1Gb+. The good news is that over 90% of Portsmouth properties can sign up to a Virgin deal.

Thanks to a partnership between City Fibre and Giganet, there's full fibre broadband in Portsmouth, albeit with limited availability. This can offer ultrafast speeds of 1Gb+ and is available (although in quite limited fashion) in the Portsmouth area.

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.

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.

Price rise = This is the additional amount added to your monthly cost after a set period, usually annually, based on the provider’s terms.

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.
