All-in-one air conditioners (no outdoor unit)

UK restock alerts · 2026

All-in-one air conditioners — also called monoblock or through-wall units — cool a room without a separate outdoor condenser. Everything sits in one indoor box, so there is no split unit to mount outside. They sell out fast across UK retailers during heatwaves.

Get alerted when a all-in-one AC restocks

All-in-one air conditioners are among the first things to sell out when the temperature climbs. Rather than refreshing shop pages by hand, tell BunnyDing to watch for you: pick the shops you care about, pay once (no subscription), and we email you a direct link the instant a all-in-one unit is buyable again — so you can check out before it’s gone.

How this compares to other no-outdoor-unit units

All-in-one is one of three no-outdoor-unit formats — portable, window and all-in-one. For a full breakdown of how they mount and vent, and which suits a flat, a rented home or a house you own, read our guide to portable air conditioners with no outdoor unit.
