Small Aromas

Small Aromas is the cheapest way onto this list. Samples run 1ml, 2ml, 3ml and 5ml, priced from £2.99 to £8.99, which puts a serious testing session - six or eight fragrances properly lived with over a fortnight - inside the price of one bad blind buy.

It holds the best review score of any UK decant service we checked: 4.9 on Trustpilot across 329 reviews. Reading what those reviewers actually say is more useful than the number. The recurring themes are glass sample bottles rather than plastic atomisers, handwritten notes in the parcel, and unrequested extras. Glass matters beyond sentiment: plastic can interfere with how a fragrance reads over hours, so a service that defaults to glass at £2.99 is making a real choice rather than a cosmetic one.

It is explicitly UK-only - the site states plainly that it does not ship outside the UK - with free tracked delivery over £30. That constraint is why it is on this list rather than despite it: this is a small British operation doing one thing carefully rather than a European storefront with a UK locale bolted on.

The standard caveat applies as it does across this whole category: they describe the products as original perfumes in various sample sizes, and that authenticity assurance is theirs, self-asserted, not third-party verified. No decant service anywhere can offer more than that.
