How Much Do Air Conditioners Without Outdoor Units Cost?
Portable and monoblock air conditioners have become a practical choice for UK households that cannot install traditional split systems. With no outdoor unit required, these appliances offer flexibility and convenience — but understanding what they actually cost is essential before making a purchase.
Staying cool during warmer months is increasingly important across the UK, and air conditioners without outdoor units — often called portable or monoblock air conditioners — are growing in popularity. Unlike traditional split systems that require an external unit fixed to an outside wall, these standalone appliances can be moved between rooms and require minimal installation. For renters, flat dwellers, or anyone in a listed building, they offer a genuinely practical solution. But before investing, it is worth understanding the full cost picture.
What Are Air Conditioners Without Outdoor Units?
Air conditioners without outdoor units are self-contained cooling devices that expel heat through a single exhaust hose, typically routed through a window or vent. They do not require professional installation of external components, making them far more accessible than traditional systems. Most models sit on the floor and can be repositioned easily. While their cooling efficiency is generally lower than split systems, they are a cost-effective and flexible option for many UK homes.
Average Purchase and Installation Costs
The average purchase and installation costs for portable air conditioners in the UK vary depending on the unit size, brand, and features. Entry-level models typically start around £200 to £350, while mid-range units with better energy ratings and higher BTU output generally cost between £350 and £600. Premium portable air conditioners, which may include heat pump functionality or smart home integration, can reach £700 to £1,000 or more.
Because these units require no external installation, professional fitting costs are usually minimal or entirely absent. If you do hire someone to set up the exhaust hose or window kit, expect to pay between £50 and £150 for a simple setup. This stands in sharp contrast to the £1,000 to £3,000 typically associated with full split-system installation in the UK.
Cost Comparison: Portable vs. Other AC Types
When doing a cost comparison, portable air conditioners without outdoor units offer a clear financial advantage in upfront costs. A standard split-system air conditioner requires both the unit price (often £500 to £1,500) and professional installation, which frequently adds another £500 to £1,500 depending on the property. Ducted systems are even more expensive, sometimes exceeding £5,000 once installation is included.
Running costs, however, are an important part of any cost comparison. Portable units tend to be less energy-efficient than split systems, meaning ongoing electricity bills can be higher. A typical portable unit drawing 1,000–1,500 watts running for several hours daily during summer can add £30 to £80 per month to energy costs, depending on usage patterns and tariff rates.

Key Features That Affect the Price
Several features influence where a portable air conditioner sits on the price scale. Units with higher BTU ratings — which indicates cooling power — tend to cost more. Models offering both cooling and heating modes, often called reverse-cycle units, are priced higher than cooling-only versions. Energy efficiency ratings (expressed as EER or SEER values) also play a role: higher-rated units cost more upfront but may save money over time. Additional features such as Wi-Fi connectivity, programmable timers, and air purification filters further push prices upward.
Where to Buy in the UK
Portable air conditioners without outdoor units are widely available from UK retailers including Currys, John Lewis, Amazon UK, and specialist appliance stores. Prices can vary between retailers, so comparing listings across multiple platforms before purchasing is advisable. Seasonal sales — particularly in early spring before summer demand peaks — can offer meaningful savings. Some retailers also offer interest-free credit options, which can make higher-end models more accessible.
Understanding the full cost of air conditioners without outdoor units means looking beyond the price tag. Factoring in energy efficiency, potential running costs, and any minor setup expenses gives a more accurate picture of the total investment. For many UK households, the combination of low upfront cost and simple setup makes these units a practical and financially sensible choice for managing indoor temperatures.
