Grain Black Friday Broadband Deals 2026: 50% Off Full Fibre

Grain, a Full Fibre broadband provider with its own network, is running an early Black Friday offer: new customers get 50% off the monthly price for up to 9 months, depending on the package. The offer is open until 11:59pm on Monday 30 November 2026, and the half-price months begin in the second month of service, after the first full bill has been paid.

The offer by package

These are the prices Grain states for most addresses on its network for November 2026, on an 18-month contract, with the totals as Grain calculates them. Grain shows the price for your own address once you enter your postcode, and the exact offer depends on the package you choose. Grain does not state a price or offer length for Full Fibre 500 on its public pages. Source: Grain’s Black Friday announcement and Grain’s offer terms, read on 1 November 2026.

When the half-price months start and end

• Month one: the full monthly price, for every package.
• Full Fibre 250: half price in month two, then £19.99 for months three to 18.
• Full Fibre 1000: half price for months two to seven, then £25.99 for months eight to 18.
• Full Fibre 2000: £14.99 for months two to ten, then £29.99 for months 11 to 18.

Because Grain states no in-contract price rises, the price after the half-price months is the price for the rest of the 18 months. That makes the total simple to check against your current broadband.

What is included

• Free standard installation: Grain charges no upfront cost for a standard residential installation. An installation outside its standard terms can carry a charge, set out in Grain’s price guide.
• No in-contract price rises: the monthly price does not go up during the 18 months.
• The same speed up as down: on every package, with unlimited data.
• No credit check, and Grain manages the switch from your current provider.
• Price Match Guarantee: Grain says it will match a like-for-like offer from another provider. It cannot be combined with another offer or discount, so ask Grain which applies before you order.

Check your postcode first

Grain builds its own Full Fibre network, so it is available at some addresses and not others. The price, the speeds and the offer for your home are shown once you enter your postcode on Grain’s site. If Grain is not available at your address, other providers’ Black Friday offers may be.

Is it a saving for you?

1. Check your current contract’s end date. Leaving before it usually means paying for the months that are left. Grain says it has options for customers still in contract; ask what applies to yours.
2. Compare the total, not the first month. Add up what your current provider would charge over the same 18 months, including any rise each April, and compare it with Grain’s total for the package you need.
3. Choose the speed you will use. The longest half-price period is on the fastest package, but a slower package can still cost less over the contract.
4. Order by 11:59pm on 30 November 2026 if you want this offer.
