Our verdict

Cuckoo Fibre suits households in GB that want full fibre with a gigabit ceiling and nothing to pay upfront, since its setup fee is £0. The trade-off is commitment: every plan runs on a 12, 18 and 24 term, and prices are reviewed each April.

Pros and cons

Pros

  • The setup fee is £0, and Cuckoo Fibre ranks 1 of 86 on that measure, so joining costs nothing extra.
  • A 1,000 Mbps ceiling places the provider at 49 of 114 on top download speed, well ahead of the middle of the table.
  • A static IP is available on the plans, which matters for home servers, game servers and reaching your own kit from elsewhere.
  • The router is included as Cuckoo Hub Wi-Fi 6 mesh included, so the monthly figure covers hardware as well as the line.

Cons

  • Prices are reviewed once a year in April, so the £29.95 entry price is not the figure you keep for the whole term.
  • Every plan runs on a 12, 18 and 24 term, and leaving early adds a termination charge for each month remaining plus any unpaid activation and router costs.
  • On price from, Cuckoo Fibre sits at 76 of 95, further down the table than its speed position suggests.

Who it suits

  • Households in GB after gigabit fibre, with 1,000 Mbps as the ceiling and £0 to join.
  • Home server owners and remote workers who want a static IP and a router in the box, since Cuckoo Hub Wi-Fi 6 mesh included comes as standard.
  • Anyone settled at one address who can sit on a 12, 18 and 24 term and accept a yearly review in April.

Who should look elsewhere

  • Cable households that want a hybrid line: Astound lists cable and fttp, a mix Cuckoo Fibre does not carry, since its own technology is fttp and fttc.
  • People who want wireless or satellite paths as a backup: EarthLink lists fttp, 5G and satellite, while Cuckoo Fibre stays on fttp and fttc.

What it does well

The headline number is 1,000 Mbps, and that is a ceiling rather than a promise. The published price list pairs each plan with a lower average speed, so read the maximum as the ceiling and the average as the fairer guide to everyday use. A static IP is available on the plans, and that is the feature which lifts this offer above an ordinary home connection. It matters if you run a home server, host game servers, or want to reach kit at home from elsewhere without an address that keeps changing underneath you. Every plan also arrives with hardware rather than leaving you to source your own, with the router listed as Cuckoo Hub Wi-Fi 6 mesh included. Taken together, the speed, the fixed address and the included kit make this a package for people who want to plug in and stop thinking about the connection. One thing to weigh is that a static address is useful only if you run something on the network. If you simply browse and stream, it is a detail rather than a reason to move.

Pricing

Entry pricing starts at £29.95 a month, and the setup fee is £0, so nothing is added to get connected. The published price list is a ladder: the entry Cuckoo plan at the bottom, Supreme Full Fibre in the middle and Hyperstream Full Fibre at the top, with each step buying both a higher headline speed and a higher average speed. Every reference plan on that list is sold on a 12, 18 and 24 term, so pick the tier you actually need rather than the top one. Two things move the monthly figure later. First, prices are reviewed once a year in April, so the £29.95 you join on is a starting point rather than a fixed rate held for the life of the plan. Second, leaving before the term ends is chargeable: the fee is a monthly termination charge for every month remaining, plus any activation and router costs you have not paid. If you expect to move home inside the term, the exit charge and the yearly review matter more than the entry figure. Read together, the entry price is low for a full fibre package with kit included, while the long view depends on how long you plan to stay.

Where it sits among rivals

Speed is where Cuckoo Fibre looks strongest. On top download speed it ranks 49 of 114 brands compared, which puts it ahead of the middle of a crowded list. On price from it sits further back, at 76 of 95. The setup fee is the outlier and the standout number: 1 of 86, the strongest of the three positions. In plain terms, you get a faster connection than most of the table and pay like the middle of it, with nothing at the door to get connected. The practical reading is that the value sits at the point of joining rather than in the monthly figure later on.

Who runs it

Cuckoo Fibre trades as Cuckoo Fibre Limited, registered in the United Kingdom. The terms set out a single market for its plans, so this is a home market provider rather than one with listings abroad, and anyone outside that market can rule it out quickly. Help runs on chat, phone and help centre. That means live chat, a phone line and written help content, which covers the three cases most households run into: a quick question, an urgent fault, and something that needs a written record. The channels are the ones providers in this category usually offer, so the support model is familiar rather than a differentiator. The provider is small enough that the published price list and the terms are short documents, which makes the commitment terms easier to read before you sign up.

Frequently asked questions

How much does Cuckoo Fibre broadband cost a month?+

Broadband starts at £29.95 a month with a £0 setup fee. The published price list is a ladder: the entry Cuckoo plan, then Supreme Full Fibre, then Hyperstream Full Fibre at the top, each with a higher headline and average speed. Every reference plan on that list is sold on a 12, 18 and 24 term, so the entry figure and the term length are the two numbers to weigh together.

Is there a setup or installation charge?+

There is nothing to pay to get connected. The setup fee is £0, which places Cuckoo Fibre at 1 of 86 on that measure. Worth knowing alongside it is the hardware: the router is part of the package, listed as Cuckoo Hub Wi-Fi 6 mesh included, so your monthly cost covers the equipment as well as the line.

What speed will I actually get?+

The top of the range is sold at 1,000 Mbps. The price list publishes a headline speed and a lower average speed for each plan, and the average is the fairer guide to daily use. Treat the maximum as a ceiling rather than a promise, and read the average for the Cuckoo, Supreme Full Fibre and Hyperstream Full Fibre tiers before you choose.

How long is the contract?+

Terms run 12, 18 and 24, so your choice is between the shorter and the longer of those rather than a rolling monthly deal. Every reference plan in the price list is sold on a fixed term. A shorter term reduces the risk if you expect to move home, while a longer one suits an address you are staying at.

What happens if I leave before the end of the term?+

Leaving early is chargeable. The fee is a monthly termination charge for each month remaining, plus the activation and router cost if you have not paid it. Since every plan runs on a 12, 18 and 24 term, the earlier you leave the more that adds to your final bill, which is worth factoring in before you sign a longer term.

Does the monthly price go up each year?+

Prices are reviewed annually in April under the terms, so the monthly figure can change during the contract rather than staying level throughout. The £29.95 entry price is therefore a starting point. Budget for a rise before you commit, and weigh it more carefully if you are considering one of the longer 12, 18 and 24 terms.

Can I get a static IP address?+

Yes, static IP is available on the plans. It is the detail most likely to matter beyond raw speed, because a fixed address helps anyone running a home server, hosting game servers, or connecting to devices at home while away. The connection underneath reaches 1,000 Mbps, so the address rather than the line is the useful part.

What router do I get and how do I get help?+

The router is included with the plan, listed as Cuckoo Hub Wi-Fi 6 mesh included, so you are not buying hardware separately on top of the monthly price. Help runs on chat, phone and help centre, which covers live chat, a phone line and written help content. That mix suits a quick chat for a small question and a call for a fault that is stopping your connection.

Where does Cuckoo Fibre operate?+

Cuckoo Fibre trades as Cuckoo Fibre Limited and is registered in the United Kingdom, with plans listed for GB. That is a single market, so anyone living outside it is not a candidate at all. Inside the market, availability still depends on whether the underlying network has reached your street, so check coverage before you commit to a term.
