Grain broadband referral code — Fibre from 250Mbps to 2Gbps, fixed-price for 18 months

Grain broadband referral code: what you save

Grain broadband has no referral code to type, and the saving comes with the link instead. Prices stay fixed for the whole 18-month contract, because Grain says there are no in-contract price rises. Grain does not show a £ amount on its home page, so no saving figure appears here, but the fixed price is the saving to plan around.

No code is needed. The offer applies to new customers at addresses on Grain's network. Open the link, enter your postcode, and choose a speed. Prices only show after that check, so each address sees its own figures.

The headline product is Full Fibre, on an 18-month contract. The home page lists a free router and standard installation, so there is no kit to buy first.

Grain in brief

Grain is a UK full fibre broadband provider. It sells symmetrical home packages from 250Mbps up to 2Gbps, on 18-month fixed-price contracts. Its speeds are symmetrical, so uploads run as fast as downloads. Its home page lists the package names, speeds and features in one place. The speed you pick depends on how many people share the connection.

Grain also sells to businesses in its fibre areas, and households in those areas are the people it is built for. Its main product is the Full Fibre range, with 250, 500, 1000 and 2000 speeds. Its price match promise compares like-for-like packages, and you get in touch before signing up. Grain publishes its offer terms on its own site, so you can read them first.

Grain's home page shows no sign-up bonus and no price until a postcode check. The package list names four Full Fibre plans, each on an 18-month contract. Each package shows its own price once your postcode is checked.

What Grain broadband gives you

Grain sells full fibre broadband for homes and businesses in its fibre areas. The Full Fibre range runs at 250, 500, 1000 and 2000 Mbps, and every speed sits on the same fixed-price contract.

Fixed prices for 18 months. Every Full Fibre plan sits on an 18-month contract. Grain says there are no in-contract price rises, so your monthly cost stays put for the whole term.

Four symmetrical speeds. Choose 250, 500, 1000 or 2000 Mbps. Symmetrical means uploads run as fast as downloads, so big uploads don't crawl.

A free router. The router comes included, so there's no hardware to buy.

Free standard installation. Grain installs the service at no charge, with no install fee to plan for.

A Price Match Guarantee. Grain says it will match a rival's price on a matching package. The match is covered in the terms below.

Automatic switching. You can opt in to automatic switching when you sign up.

How to start. Check your postcode on grainconnect.com, pick a speed, opt in to automatic switching if you want it, then get installed free.

Why this link is the one to use

Grain needs no code, so the link does all the work. HonestCodes read the offer on Grain's own pages on 17 October 2026. Use https://honestcodes.co.uk/go/grain to reach Grain, and the route is printed in full so nothing is hidden.

HonestCodes re-checks this offer on the date shown at the top of the page. Each re-check reads Grain's pages again, not an old list copied from somewhere else.

Undated coupon lists and expired social posts are a different story. They keep showing codes long after the code has died. This page has no code to expire. The offer is the link and the switch, with nothing to type.

Some details are not on Grain's pages yet. The home page shows no price or sign-up bonus. Prices appear only after a postcode check, so each reader sees their own figure. Grain's terms index lists Switch and Ditch, Price Match and Refer a Neighbour, and the full wording sits on Grain's terms page.
