How the reward lands

Open the Osmio Water link and add items to your basket. No code is needed: the free delivery applies once your basket goes over £25. Your basket total is what counts, so add everything you want first. The link lands on the Zero 2.0 product page, so you can compare it with the figures above.

The offer covers UK mainland orders only. Osmio doesn't say how long the offer runs or which items it excludes. It doesn't publish separate terms for the offer. The 90 day returns are the other part of the deal.

Order before 3pm, Monday to Friday, for same-day dispatch. The countertop Zero needs no plumbing work. Osmio aims its range at homeowners, renters and students who want filtered water at home. There is no welcome discount on this offer, so free delivery is the reward.

What the Osmio Zero actually does

The TopReferrals link opens the Osmio Zero 2.0 Reverse Osmosis System, listed at £495.00. Reverse osmosis is the process at the heart of every Zero model. It pushes tap water through a membrane. You get filtered, pure water at your kitchen tap.

Osmio's countertop range needs no plumbing. The countertop Zero 3.0 hydrogen model is listed at £649.99, in white or black.

If you want fitting done for you, Osmio lists installed Fusion models: £495.00 for the 2.0 and £649.99 for the 3.0 hydrogen version.

Homeowners, renters and students can skip bottled water. Filtered water comes from the tap instead. The countertop range is the simplest place to start for most homes.

Either way, the TopReferrals link takes you straight to Osmio's own site, where these prices are listed.

Filters, distillers and spares

Not ready for a full system? Osmio also sells countertop distillers. The 4L Stainless Steel Countertop Water Distiller is listed at £169.00, and its 3.8L Distiller Jug at £34.99.

Replacement filters keep either setup running, so you can reorder when a cartridge needs changing. Shower filters and whole-house systems also sit in the Osmio range. The HT+ Home & Office Direct Flow model also sits at £495.00.

Each product has its own page on Osmio's site, so you can compare models before you buy.

This Christmas at Osmio Water

A countertop Zero makes a practical gift for a home upgrade. A smaller order could be a filter or the £34.99 distiller jug.

Gift buyers can use the TopReferrals link, then pick a product on Osmio's own site.

Order before 3pm Monday to Friday for same-day dispatch. Orders over £25 to UK mainland addresses ship free.

Osmio doesn't say when its Christmas cut-off falls.

The fine print, in plain words

Free delivery covers UK mainland orders over £25. Osmio's returns window is 90 days. The TopReferrals link opens the Zero 2.0 page on Osmio's site, and no welcome discount is added to it. Orders placed before 3pm, Monday to Friday, dispatch the same day. Osmio doesn't say how long this offer runs, and it doesn't list exclusions. Osmio doesn't say what its Christmas order dates are either. Prices come from the category page checked on 18 October 2026. Start at the Osmio Water link.

How TopReferrals checked this

TopReferrals checked Osmio Water's own pages on 18 October 2026. The homepage at osmiowater.co.uk showed free UK delivery on orders over £25, plus 90 day returns. The Reverse Osmosis Water Filters category page gave the prices for the countertop Zero 3.0 and Zero 2.0 systems, the Fusion installed systems, the HT+ direct flow system, the distiller and the 3.8L distiller jug. Each figure in the prices comes from that page. That same page showed same-day dispatch for orders placed before 3pm, Monday to Friday. The TopReferrals link opens the Zero 2.0 product page, checked on the same date. Every figure above was read from the brand's own page on that date. Shipping, returns and prices are the only details these pages set out for the offer. Osmio Water doesn't publish a sign-up discount, an expiry date for its delivery offer, or Christmas cut-off dates. TopReferrals re-checks the offer on the date shown at the top of the page.
