FAQs
Air Conditioning Questions, Answered
Everything most people ask before booking a Lewken air con install.
How much does air conditioning installation cost?
Guide prices for fully installed Bosch air conditioning start from £1,495 for a small room and rise based on room size, unit type and installation complexity. Use our instant quote tool to see a price for your specific room in under a minute.
What brand of air conditioning do you install?
We install Bosch air conditioning units — one of the most trusted names in heating and cooling. Bosch is known for quiet operation, high efficiency, German-engineered reliability and an excellent up to 5-year manufacturer warranty. We’re fully F-Gas certified, so every install is legally compliant and properly registered.
Can air conditioning heat as well as cool?
Yes. Modern Bosch air conditioning units use reverse-cycle technology, which means the same unit cools in summer and provides efficient heating in winter — ideal for UK weather.
How long does installation take?
Most home air conditioning installations are completed in less than a day, although exact times vary based on access, pipework runs and whether multiple units are being fitted.
Is air conditioning suitable for bedrooms?
Absolutely. Modern Bosch wall-mounted units have a whisper-quiet sleep mode, gentle airflow and precise temperature control — perfect for sleeping comfortably on warm nights.
Do I need planning permission?
For most UK homes, planning permission is not required for a standard wall-mounted air conditioning install. Listed buildings, flats and properties in conservation areas may need approval — we’ll advise during the free survey.
