Designer candles from houses like Diptyque, Jo Malone, and Byredo often sell for £50 to £90, and a lot of that price covers packaging, brand, and retail markup rather than the fragrance oil itself. A good "dupe" is not a fake or a copy — it is a candle that leans on the same fragrance family (woody, floral, amber, citrus) using quality fragrance oil and a clean-burning wax, at a fraction of the price. What actually determines whether a dupe works is fragrance load (how much oil is in the wax) and wax quality, not the brand name on the jar. UK high-street retailers have leaned hard into this space recently, with own-brand ranges built around the same popular scent families as the designer originals. When comparing options, check for soy or coconut wax, a stated burn time, and — where possible — a review mentioning both cold throw and hot throw, not just "smells amazing in the box."
