Grain Refer a Friend — Full fibre up to 2Gbps, fixed price, free router

2Gbps. That is the fastest package on Grain's full fibre list, and it runs at the same speed both ways. Through the TopReferrals link you get fixed-price full fibre broadband, a free router and free standard installation. Speeds run from 250Mbps up to 2Gbps, so households and businesses in Grain's fibre areas can pick the speed that suits them.

What you get, in numbers

Package	Contract	Monthly price
Full Fibre 250	18 months	Shown after a postcode check
Full Fibre 500	18 months	Shown after a postcode check
Full Fibre 1000	18 months	Shown after a postcode check
Full Fibre 2000	18 months	Shown after a postcode check

Grain fixes the price for the full 18 months and says there are no in-contract price rises. Every package runs on the same contract length, so speed is the only choice you make. Grain shows monthly prices only after a postcode check, so the figure you see depends on your address. Speed is the main decision, so compare the four rows against the homes and devices you run.

How the reward lands

Start with https://topreferrals.co.uk/go/grain. It opens Grain's home page, where a postcode check confirms your address sits on Grain's network. Pick a speed from the 250, 500, 1000 or 2000 packages. Then opt in to automatic switching, so the switch is handled for you. Grain arranges your installation free of charge, and the router comes free too, so there is no hardware bill to plan for. Businesses with a fibre address can follow the same steps.

Grain's Price Match Guarantee sits alongside the packages. It covers like-for-like packages only, and it needs contact with Grain before you sign up. Grain doesn't say how much the new-customer discount takes off your bill, or when it first appears. It also doesn't say when this offer ends. You can see the monthly figure for each speed once you enter your postcode, so the postcode check is the quickest way to see what applies at your address.

Grain broadband: what you actually get

Grain sells home broadband on full fibre. The packages are Full Fibre 250, 500, 1000 and 2000. Speeds run from 250Mbps up to 2Gbps. Every speed is symmetrical, so uploads run as fast as downloads. Upload matches download, so video calls and file uploads stay quick.

Each package sits on an 18-month contract with a fixed price. You pay the same fixed price for the whole 18 months. Grain says there are no in-contract price rises. Your router comes free, so there is no kit to buy. Standard installation is free too.

Grain sells its packages as fixed-price gigabit broadband. Households with several devices online at once can choose the speed that fits.

Grain doesn't publish a monthly price. You see prices only after a postcode check on grainconnect.com.

How the offer reaches you, step by step

The TopReferrals link opens Grain's home page, where the offer is listed. From there, you:

• Check your postcode on grainconnect.com.
• Pick a speed from the four packages.
• Opt in to automatic switching. It is an option you tick at sign-up.
• Get installed free.

Grain's Price Match Guarantee comes with the offer. Grain calls this its Price Match Guarantee. Before you sign up, Grain asks you to get in touch about a like-for-like package. Grain doesn't say how long installation takes.

Homes and businesses in Grain's fibre areas

The offer is open to new customers at addresses on Grain's network. A postcode check tells you whether your address is covered. Grain also serves businesses in its fibre areas. Start by checking your postcode before you pick a speed. Grain's home page shows the full list of packages once your postcode is checked.

The fine print, in plain words

• Who qualifies: the offer is for new customers at addresses on Grain's network. A postcode check on grainconnect.com tells you whether yours does.
• Contract length: packages run on an 18-month fixed-price contract. Grain's home page says there are no in-contract price rises.
• Price Match: the Price Match Guarantee needs a like-for-like package. You make contact with Grain before you sign up.
• Switching: you opt in to automatic switching when you order.
• Included extras: the router and standard installation are free.

• Refunds and delivery: Grain doesn't say how refunds work or when installation happens.

Promo codes, coupons and vouchers

How TopReferrals checked this

TopReferrals checked Grain's own pages on 17 October 2026. Each group of facts came from a different Grain page, so each is named here. The grainconnect.com home page lists the Full Fibre 250, 500, 1000 and 2000 packages, the 18-month contract, the promise of no in-contract price rises, and the free router with standard installation.

The home-broadband home-packages page gives the package list, but monthly prices appear only after a postcode check. The package pages were read on the same day. The price-match page describes the Price Match Guarantee. The legal offer-specific terms index on the grainconnect.com domain lists the Switch & Ditch, Price Match and Refer a Neighbour terms; its bodies did not render when read, so those details are not quoted here.

Grain doesn't say how long the offer runs, or whether a minimum spend applies. Eligibility covers new customers at addresses on Grain's network, confirmed by postcode check. TopReferrals re-checks the offer on the date shown at the top of the page.
