Cuckoo Broadband Deals: Compare Plans, Prices & Coverage
Cuckoo does things differently to most UK broadband providers. No phone bundles. No TV packages. No legacy copper connections. It’s broadband-only, full-fibre only, and it keeps its plan lineup refreshingly simple: three speed tiers, a free premium router, and a choice of contract lengths.
That simplicity is genuinely appealing. But Cuckoo isn’t available everywhere, and there are a few things worth understanding before you commit.
“Cuckoo is one of a small group of UK providers that has made a deliberate choice to go full-fibre only. That’s a meaningful commitment, but it also means availability is genuinely limited. Our advice is always to check your postcode first, then compare the total cost across the contract term, including that £3 annual April increase, before deciding whether Cuckoo is the right fit for your household.”

Who are Cuckoo?
Cuckoo is a broadband-only provider that operates exclusively over full-fibre (FTTP) infrastructure, primarily on the CityFibre network. Unlike BT, Sky, or TalkTalk, it doesn’t run on the Openreach network that most mainstream providers share. Different physical network, different coverage.
Because Cuckoo is full-fibre only, it’s not available at every UK address. Coverage depends entirely on whether FTTP infrastructure has been built out in your area. Before doing anything else, check what’s available at your postcode to see if Cuckoo covers your home.
All pricing in this article is correct as of April 2026. Broadband deals change regularly, so always verify current prices before signing up.
What is full fibre (FTTP) and why does it matter?
FTTP stands for fibre to the premises. It means a fibre-optic cable runs all the way from the exchange directly into your home, with no copper wire involved in the final stretch. This is different from FTTC (fibre to the cabinet), where fibre reaches a street cabinet but the last leg into the home still uses old copper phone lines.
That distinction matters a lot. Copper degrades over distance and struggles during peak hours, which is why your “fibre” broadband often doesn’t hit the speeds advertised (spoiler: it’s probably FTTC). Full fibre consistently delivers faster, more reliable speeds, and both upload and download performance are significantly better.

Cuckoo broadband plans and pricing
Cuckoo keeps its lineup simple with three plans. All are FTTP, all include unlimited data, and all come with a free eero Pro 6E router (which retails at roughly £249.99) and free installation.
| Plan | Speed | 24-month price | 12-month price | Promo (24-month) |
|---|---|---|---|---|
| C-150 | 150Mbps | From £27/mo | From £33/mo | £13.50/mo for 6 months |
| C-500 | 500Mbps | From £32/mo | From £40/mo | £16/mo for 6 months |
| C-900 | 900Mbps | From £35/mo | From £47/mo | £17.50/mo for 6 months |
Prices shown are correct as of April 2026 and are inclusive of VAT. Always verify current pricing directly with Cuckoo before signing up.
Contract length options: rolling, 12-month, and 24-month
Cuckoo offers three contract lengths. Rolling one-month contracts give you maximum flexibility but come with a £60 setup fee. Both 12-month and 24-month plans waive that fee entirely.
The 24-month plans currently carry the best value thanks to the half-price promotional period (more on that below). If you’re not sure about committing for two years, 12-month broadband deals offer a middle ground, though you’ll pay a bit more per month.
Worth considering that Cuckoo applies a £3 per month annual price increase on their 24-month contracts. This is a common practice from broadband providers, as mainstream providers such as BT, EE, Sky and Virgin Media also increase prices annually.

Current Cuckoo broadband deals and promotions
As of April 2026, Cuckoo is offering 50% discount on many of their 24-month full fibre deals. For instance, the C-500 is priced at £18.50 for the first six months and then rises to £37.00 per month. That is excellent value for 500Mbps.

What do you get with a Cuckoo broadband package?
Every Cuckoo plan includes unlimited data with no traffic shaping or fair-use caps, free installation, and a free eero Pro 6E router. The eero Pro 6E supports Wi-Fi 6E, which means better performance across multiple devices and stronger coverage in larger homes. If you’re curious about how it compares to other options, have a look at our guide to the best wireless routers.
Cuckoo also provides UK-based customer support.
Things to consider before signing up
Coverage is the biggest question mark. Cuckoo only operates where FTTP infrastructure exists on the CityFibre network or similar alt-nets. Major cities tend to be well served, but suburban and rural areas often aren’t. Ofcom’s Connected Nations data shows full-fibre coverage has been expanding steadily, but it still doesn’t reach every UK home.
No bundles whatsoever. Cuckoo is broadband-only. If you want a TV package from Sky or a home phone line, you’ll need to arrange those separately. For some people that’s a simplification. For others, it’s an inconvenience.
The rolling contract maths can be tricky. Yes, a one-month rolling plan offers flexibility, but the £60 setup fee eats into that benefit quickly. If you think you’ll stay more than a couple of months, a 12-month deal usually works out cheaper.
How does Cuckoo compare to other providers?
Cuckoo’s pricing is competitive, but it’s not always the cheapest. Here’s how some alternatives compare as of April 2026:
- TalkTalk Full Fibre 150: £24/mo on a 24-month contract (also available on CityFibre), plus a £75 gift card. That’s notably cheaper than Cuckoo’s C-150 at £27/mo, though TalkTalk’s price rises to £28/mo in year two.
- EE Full Fibre 500: £29.99/mo on a 24-month deal with an £80 gift card and up to £300 switching credit. Comparable speed to Cuckoo’s C-500, and the gift card sweetens the deal.
- Virgin Media M500: £23.99/mo for 516Mbps on cable. Cheaper upfront, but mid-contract rises push it to £31.99 in year two.
- BT Full Fibre 500: £32.99/mo with a £150 reward card and a £34 setup fee. Similar monthly cost to Cuckoo’s C-500, but with BT’s wider Openreach availability.
Where Cuckoo stands out is in what you don’t pay for. The free eero Pro 6E router is worth roughly £250, there’s no setup fee on fixed contracts.
How to switch to Cuckoo broadband
Step 1: Check availability. Use Switchity’s postcode checker or Cuckoo’s own tool to confirm FTTP coverage at your address.
Step 2: Pick your plan and contract length. C-150 handles lighter use fine, C-500 suits most households comfortably, and C-900 makes sense if you’ve got a house full of people streaming, gaming, and working from home simultaneously.
Step 3: Sign up. Cuckoo coordinates the installation and posts a router ahead of your go-live date. Installation is free on all fixed-term contracts.
Step 4: Check your current contract. Cuckoo handles the switching process, but if you’re still within a minimum term with your existing provider, you could face an early exit charge. Use Switchity’s early termination fee calculator to check what you might owe.
You don’t need a traditional phone line for Cuckoo. It runs entirely over the fibre network.
Is Cuckoo broadband worth it?
For the right household, Cuckoo is a strong choice. If you’re in a covered area, want genuine full-fibre speeds, and like the idea of a simple broadband-only setup with a premium router included, it ticks a lot of boxes. The half-price introductory deal on 24-month plans makes the first year particularly good value.
It’s less ideal if you’re outside CityFibre’s footprint, need a TV or phone bundle, or simply want the absolute cheapest monthly cost. Providers like TalkTalk and Virgin Media often undercut Cuckoo on headline price, even if their total contract costs and mid-term rises can muddy the comparison.
If Cuckoo isn’t available at your address, or you want to see how it stacks up against the full market, compare all broadband providers to find the best deal for your home.
