Plusnet Full Fibre 300: Speeds, Price and Who It Suits

Plusnet Full Fibre 300 is a full fibre broadband package delivering a 300Mb average download speed over the Openreach network, sold on a 24-month contract from around £23.99 a month on current promotional deals. It uses a Fibre to the Premises (FTTP) connection, meaning the fibre runs directly to your home rather than stopping at a street cabinet, so the advertised speed is far more consistent than older part-fibre products.

For a UK household weighing up speed against price and contract length, the real questions are whether 300Mb is more than you need, how much you actually pay once mid-contract rises kick in, and how it stacks up against Plusnet’s cheaper and faster tiers. Free Price Compare sources package and speed detail from Plusnet’s own pages and network data from Ofcom, so you can decide with the numbers in front of you rather than the marketing.

Quick Answer: Plusnet Full Fibre 300

  • Full Fibre 300 delivers a 300Mb average download speed and around 50Mb upload speed over the Openreach FTTP network (Plusnet).

How much does Plusnet Full Fibre 300 cost per month?

Plusnet Full Fibre 300 currently costs from around £23.99 a month on a 24-month contract on leading promotional listings, usually paired with a Reward Card and a one-off set-up fee of about £20. Plusnet’s own residential price guide lists Full Fibre 300 at £39.99 a month for new customers or those last re-contracted on or after 5 August 2025, which is the standard non-promotional rate. The gap between the promotional price and the price guide rate matters, because deals are time-limited and the underlying contract price is what your future renewals are benchmarked against. Reward Card values also differ by channel and campaign, with figures such as £50 and £145 appearing across different listings, so read the exact terms on the deal you order.

Element Typical figure
Promotional monthly price From around £23.99
Plusnet price guide rate £39.99 (new/recent re-contract)
Set-up fee Around £20
Contract length 24 months
Reward Card £50 to £145 depending on listing

Figures are indicative and may change.

To sense-check value, Ofcom’s Pricing Trends for Communications Services in the UK report (pricing data October 2024) found independent full-fibre providers offered 900Mbit to 1Gbit deals from around £26 a month, against about £39 a month for the cheapest comparable deal from a larger provider. That is a useful yardstick, not a live quote, but it shows why comparing across the whole market before renewing usually pays.

Do the prices increase mid-contract?

Yes, Plusnet Full Fibre 300 prices increase during the contract on set dates. Current deal listings show the monthly price stepping up from the promotional rate to around £27.99 from 31 March 2027 and around £31.99 from 31 March 2028, so the headline price is not what you pay for the whole 24 months. Since 2024, UK broadband providers have moved away from CPI-linked percentage rises towards fixed pounds-and-pence increases written into the contract from the start, following clarity requirements from Ofcom. That change is meant to make future rises predictable, and it means you should budget for the highest figure in the schedule, not the introductory one. Ofcom’s TV broadcast licence tariffs use a **progressive sliding scale**, so future fees are more predictable and you should budget for the **highest band rate** rather than the introductory rate.

When you compare the true cost, add up every month at each price tier over 24 months, then subtract any Reward Card value. A deal with a higher Reward Card but steeper rises can work out dearer than a plainer one, so the average monthly cost over the full term is the number that matters. If you are renewing rather than joining as a new customer, it is worth checking what the standard price guide rate would be at the end, because that is where you land if you do nothing.

Is 300Mbps fast enough for my household?

300Mbps is fast enough for the large majority of UK households, including busy homes with several people streaming, gaming and working from home at the same time. As a rough guide, a single 4K Netflix stream needs around 15 to 25Mbps, a video call needs about 3 to 5Mbps, and online gaming uses very little bandwidth but benefits from low latency, which FTTP provides. Run four 4K streams, a couple of video calls and a games console together and you are still comfortably inside 300Mbps with headroom to spare. Plusnet positions Full Fibre 300 at medium to large households with multiple simultaneous users, which matches the arithmetic. Ofcom’s UK Home Broadband Performance report (data November 2023) found the average UK home download speed was 69.4Mbit/s, so 300Mb sits well above typical usage.

The main reason to go higher than 300Mb is regular large file transfers, such as uploading video, backing up to the cloud or working with big datasets, where upload speed and raw throughput count. For everyday use, standard streaming, browsing, calls and gaming, most homes never come close to saturating 300Mb, so a cheaper tier can be the more sensible buy. If you want to see how the numbers scale up, our explainer on whether 900Mb broadband is worth it sets out where the extra speed helps.

What are the upload speeds and is there a minimum speed guarantee?

Full Fibre 300 offers an upload speed of around 50Mb alongside its 300Mb average download speed, according to retail listings for the package. Because it runs on an FTTP connection, upload performance is far better than the old part-fibre products that shared copper for the final stretch, which is what makes it stronger for video calls, cloud backups and sending large files. Under the Ofcom Broadband Speeds Code of Practice, providers that sign up must give you a realistic estimated speed at the point of sale and a minimum guaranteed speed, and let you leave without penalty if speeds fall persistently below that floor after they have had a chance to fix it. Ofcom’s voluntary code says providers must give you a **minimum guaranteed download speed** at sale, and if speeds stay below that level they must try to fix the problem within **30 days** before you can leave without penalty; for xDSL this floor is the **10th percentile** of similar customers, and for cable/FTTP it is at least **50% of the advertised speed**.[7][15][18]

Plusnet is part of BT Group and sells on the Openreach network, so it operates within these speed and consumer-protection frameworks. The exact minimum guaranteed speed for your address is shown during the order process, based on your line, rather than a single national figure, so check the personalised estimate Plusnet gives you before committing. If your delivered speed is consistently well below the estimate, keep records and raise a fault, because that evidence supports your right to a resolution or exit.

Plusnet Full Fibre 300 or 500: which should you choose?

Choose Full Fibre 300 if your home streams, calls and games heavily but rarely moves very large files, and step up to Full Fibre 500 only if you regularly upload big content or want extra headroom for a very connected household. The 300Mb tier already covers the vast majority of everyday use, so the higher tier is often paying for capacity you will not use. Full Fibre 500 makes more sense for larger households running many devices continuously, home workers shifting big datasets, or anyone who simply wants the fastest reliable connection their budget allows.

Price is the deciding factor for most people, because the speed jump from 300 to 500 rarely changes the day-to-day experience for standard use. If you want to weigh the tiers directly, compare this guide with our detail on Plusnet Full Fibre 500, and if 300Mb feels like more than you need, the cheaper Plusnet Full Fibre 145 and Plusnet Full Fibre 74 tiers are worth a look.

Is Plusnet Full Fibre 300 good, and is it FTTP?

Full Fibre 300 is a genuine Fibre to the Premises (FTTP) product, meaning the fibre runs all the way into your home rather than stopping at a street cabinet, which delivers more consistent speeds than older fibre-to-the-cabinet packages. Running on the Openreach full fibre network, its performance is comparable to other providers selling the same underlying line, so the practical difference between providers comes down to price, contract terms, router and support rather than the raw connection. Full fibre now reaches 82% of UK homes, around 24.9 million premises, and gigabit-capable broadband reaches 89% of residential premises, according to Ofcom’s Connected Nations update (data as of January 2026), so availability is strong for most postcodes.

Whether it is good value depends on the deal in front of you and how it compares once mid-contract rises are included. Plusnet’s Full Fibre packages come with a supplied router, and Plusnet permits you to use your own router if you prefer, though it will not provide support for third-party hardware. As with any FTTP tier, always confirm your address is served, check the personalised speed estimate, and compare the whole-of-term cost against rival full fibre deals before signing.

Does Plusnet Full Fibre 300 include a landline?

Full Fibre 300 is typically sold as a broadband-only product without a traditional landline, reflecting the wider UK shift away from bundled phone lines as full fibre replaces the old copper network. As FTTP does not use the copper phone line, any calling service is delivered digitally over the internet rather than through a separate landline, and many households no longer take a phone package at all. If you rely on a home phone number, check the calling options at the point of sale and confirm how the number is handled, because arrangements vary by product and provider. Ofcom says UK geographic numbers starting **01** or **02** are charged at up to **16p per minute from landlines** and **3p to 65p per minute from mobiles**, while **0800** and **0808** numbers are **free** to call. [1]

The move to digital voice is being coordinated across the industry as Openreach retires the analogue network, so this is not specific to any one provider. For a lower-cost alternative that some households prefer, our guide to Plusnet Fibre 66 covers the cheaper end of the range, which can suit smaller homes that do not need 300Mb.

FAQs about plusnet full fibre 300

How fast is Plusnet Full Fibre 300 in real use?

Full Fibre 300 delivers a 300Mb average download speed and around 50Mb upload over the Openreach FTTP network. Real-world speeds over Wi-Fi can be lower than a wired connection because of distance from the router, walls and interference, so for the fastest result connect key devices by Ethernet or sit closer to the router.

What router comes with Plusnet Full Fibre 300?

Full Fibre packages come with Plusnet's supplied Hub router, which is included in the price. You can use your own router if you prefer, but Plusnet will not provide technical support for third-party hardware, so most households find it simpler to start with the supplied hub and only switch if they have a specific need.

Is Plusnet a good broadband provider?

Plusnet is part of BT Group and sells broadband on the Openreach network, so its full fibre connection quality matches other providers using the same lines. It is generally positioned as a value, no-frills provider, and the practical differences between it and rivals come down to price, contract terms, Reward Cards and customer support rather than the underlying connection.

Can I keep my landline number with Full Fibre 300?

Full Fibre 300 is usually sold as broadband-only, and because FTTP does not use the old copper line, any phone service is delivered digitally over the internet. If keeping your existing number matters, check the calling options and number transfer terms at the point of order, as arrangements differ between products and providers.

What happens to my price at the end of the contract?

At the end of the fixed term you typically move onto Plusnet's standard price guide rate unless you re-contract or switch. That standard rate is higher than most promotional prices, so it is worth comparing the market and negotiating a new deal near the end of your term rather than letting it roll on automatically.

Is it worth paying more for Full Fibre 500 or 900?

Higher tiers are worth it mainly if you regularly upload large files, run a very connected household with many simultaneous heavy users, or simply want maximum headroom. For standard streaming, video calls and gaming, 300Mb rarely gets saturated, so the extra speed often makes little practical difference for everyday use.

How much will Full Fibre 300 cost over the full 24 months?

To find the true cost, add up each month at every price tier across the 24-month term, then subtract any Reward Card value. Because current deals include stepped rises, such as to around £27.99 from 31 March 2027 and around £31.99 from 31 March 2028, the average monthly cost over the term is higher than the introductory price.

Can I get Full Fibre 300 at my address?

Full fibre reaches 82% of UK homes, around 24.9 million premises (Ofcom, data as of January 2026), so availability is strong but not universal. Enter your postcode during the order or comparison process to confirm the Openreach FTTP network is live at your property before choosing this package.

What is the minimum guaranteed speed on Full Fibre 300?

Under the Ofcom Broadband Speeds Code of Practice, providers give a personalised minimum guaranteed speed at the point of sale based on your specific line, rather than a single national figure. Check the estimate Plusnet shows during your order, and if delivered speeds stay persistently below that floor after a fault has been raised, you may have the right to leave without penalty.

How long does it take to switch to Plusnet Full Fibre 300?

Switching timescales depend on whether an engineer visit is needed to activate FTTP at your property. Since September 2024, most broadband switches between providers on the Openreach network use the One Touch Switch process, which over 2 million customers used by the end of 2025 (Ofcom) to move provider with less admin.

Does Full Fibre 300 come with unlimited usage?

Full Fibre 300 is sold with unlimited usage, so there is no monthly data cap to worry about regardless of how much you stream, download or upload. This makes it suitable for households with heavy streaming, gaming and remote-working demands without the risk of overage charges.

Can I use Full Fibre 300 without a landline?

Yes, Full Fibre 300 works without a traditional landline because FTTP runs entirely over fibre rather than the copper phone network. Many households now take broadband on its own, and any calling service is provided digitally over the connection rather than through a separate analogue line.
