Mitsubishi Electric and Daikin are consistently the two most recommended air conditioning brands for UK domestic and light commercial use. Both make excellent products. Both carry strong warranties. Both are significantly better than budget alternatives. But there are real differences between them — and the right choice depends on your specific situation.
We install both brands regularly across Surrey, Sussex and South London. Here is an honest comparison based on our experience with both.
Brand Overview
Mitsubishi Electric
Mitsubishi Electric (not to be confused with Mitsubishi Heavy Industries, which is a separate company with a separate air conditioning range) is a Japanese manufacturer that has been making air conditioning systems since the 1960s. Their UK residential range centres on the MSZ series — the MSZ-AP (entry level), MSZ-AY (mid-range) and MSZ-LN (premium). Their commercial range includes the City Multi VRF system which is one of the most widely specified commercial air conditioning systems in the UK.
Daikin
Daikin is a Japanese manufacturer and the largest air conditioning company in the world by revenue. Their UK residential range includes the Emura (premium design-led), Perfera (high efficiency), Stylish and the more affordable Sensira series. Daikin manufacture their own compressors — many competitors buy in compressors from third parties — which gives them strong control over quality and reliability.
Efficiency — How They Compare
Both brands produce highly efficient inverter-driven systems. The headline SCOP (Seasonal Coefficient of Performance) figures for heating and SEER figures for cooling are comparable at equivalent price points. In our experience, both brands deliver on their rated efficiency figures in real-world conditions.
Daikin’s Perfera series is notably efficient — the 2.0kW and 2.5kW models carry some of the highest SCOP ratings available in the UK residential market. Mitsubishi Electric’s MSZ-LN is comparable at the premium end.
For most domestic applications — bedroom or living room cooling and supplementary heating — the efficiency difference between the two brands at equivalent price points is negligible in practice.
Noise Levels
This is where Mitsubishi Electric has a genuine edge for bedroom installations. Their MSZ-AP and MSZ-LN series are among the quietest air conditioning units available — the MSZ-LN25 operates at 19dB(A) at its lowest fan speed, which is quieter than a whisper. If you are installing in a bedroom and noise is a priority, Mitsubishi Electric is our most frequent recommendation.
Daikin’s Perfera and Emura units are also very quiet — typically 20-22dB(A) at minimum fan speed — and most people cannot tell the difference in practice. The Daikin Sensira (entry level) is noisier at around 26dB(A) minimum, which is audible in a quiet bedroom.
Design and Aesthetics
Daikin has invested more in design at the premium end. The Emura series is a genuinely beautiful piece of industrial design — a curved white or silver unit that looks deliberately placed rather than bolted on. The Stylish series is similarly well-proportioned. If aesthetics matter to your client and they are paying premium prices for a premium interior, Daikin Emura is hard to beat visually.
Mitsubishi Electric’s MSZ-LN has an attractive design but is more conventional. Their premium units are available in multiple colours including pearl white, ruby red and onyx black — which is a genuine differentiator for design-conscious customers.
Reliability and After-Sales
Both brands have strong reliability records based on our experience. In several years of installing and servicing both, we see very few warranty failures from either Mitsubishi Electric or Daikin compared to budget brands. When faults do occur, both manufacturers have good UK parts availability and technical support.
Mitsubishi Electric’s UK distribution is well established with strong parts availability. Daikin operates its own UK service network and parts distribution. For commercial installations where downtime is critical, both brands offer service agreements and rapid parts supply.
Cost Comparison
At equivalent specification, Daikin and Mitsubishi Electric are closely matched on price. A 2.5kW Mitsubishi Electric MSZ-AP25 installed typically costs £1,200-1,500. A Daikin Sensira 2.5kW is comparable. Moving to the premium tier — Mitsubishi MSZ-LN25 or Daikin Perfera 2.5kW — installed prices typically run £1,600-2,200.
The Daikin Emura premium design units carry a price premium over comparable performance units — you are paying partly for aesthetics. If the room design justifies it, that is a reasonable choice. If not, the Daikin Perfera delivers equivalent performance for less.
Our Recommendation by Application
Bedroom installation where noise is critical: Mitsubishi Electric MSZ-LN or MSZ-AP. The noise levels are class-leading and the heat pump efficiency is excellent.
Living room or open-plan space where design matters: Daikin Emura or Stylish. Better looking units in a space where they will be seen.
Home office or utility room where budget matters: Samsung or LG deliver excellent performance at lower cost. Neither Mitsubishi nor Daikin is necessary for a room where aesthetics and minimum noise are less critical.
Commercial installation: Both brands perform well. Mitsubishi City Multi and Daikin VRV are the two most specified commercial VRF systems in the UK and both have excellent track records. Choice often comes down to installer preference and parts availability in the area.
The Honest Answer
You cannot make a wrong choice between Mitsubishi Electric and Daikin at equivalent price points. Both are significantly better than cheaper alternatives. The differences matter at the margins — Mitsubishi Electric has the edge on minimum noise levels, Daikin has the edge on design aesthetics at the premium end. For most installations the better question is which specific model within either brand is right for your room size, budget and requirements.
