Best portable air conditioners under £300
Below £300 the trade-offs get sharper: most units in this band are single-hose and 7-9k BTU. We rank them by verified live price, Amazon rating, and how loud they actually run. Anything we couldn't verify against a live retailer price is excluded — no guesses.

How we rank these products
CoolCompair ranks products by a transparent four-factor model: verified live retailer price, real Amazon rating count and average score, manufacturer specs (BTU, dB, energy rating), and an editor score from our hands-on testing protocol. We do not accept paid placements. We earn an affiliate commission only when you click through and buy — the rankings would be identical without that commission.
