UK referral codes by category

Banking. For what you actually receive as the new customer, Monzo pays the most — a Personal account lands a mystery £20/£50/£100 (typically £20, up to £100), and a Business account a guaranteed £50, both to both sides. Revolut's campaign pays a flat £50, but that bonus goes only to the referrer, not to you — so for the new customer Monzo is the one that actually pays you.

Software, by a clear margin. Railway ($20 free deploy credit) and Wispr Flow (one free month of Pro with code HONEST20) both apply at sign-up with no card capture, no minimum spend and no waiting period. Cashback (TopCashback's £20 bonus) is slower but reliable — it releases once your tracked cashback reaches £10.

HonestCodes maintains 16 editorial category slots (banking, investing, money-transfer, energy, mobile, broadband, food, transport, travel, insurance, fashion, software, fitness, rewards). Only categories with at least one verified live brand are visible — currently 8 (banking, payments, telecoms, transport, travel, software, fitness, rewards). The remaining slots reappear when HonestCodes verifies a live brand in them. Hidden categories return 404 to crawlers and are excluded from the sitemap and llms.txt.

No — each brand is listed under its primary product. If a brand's programme spans two (e.g. a banking app that also offers travel insurance), the editor picks the one a typical UK reader would search for and crosslinks to related codes from the brand page.
