London mostly lacks air conditioning because the city’s mild historical climate made it an unnecessary expense. British buildings were specifically designed to retain heat for freezing winters, and many homes are older and lack the structural cavities needed for modern installations.
Without air conditioning or traditional power grids, the Amish stay cool using time-tested, natural methods. They rely heavily on strategic architectural design, natural ventilation, modified routines, and manual cooling techniques to survive the summer heat.
The Rule of 5000 Rule is simple: Multiply the cost of the needed repair by the age of your air conditioner. If the result is greater than 5000, AC replacement is generally the smarter choice. If it's less than 5000, a repair might still be worth the investment.
Owning and operating an air conditioner in the UK is entirely legal. There are, however, regulations you must comply with: F-Gas Regulations: These are UK-wide laws that ensure systems using fluorinated gases are installed and maintained safely. Only certified engineers can handle refrigerants.
A Mild Climate - Until Now
Historically, the UK's damp, mild summers simply didn't demand air conditioning. A few warm days were manageable with open windows or a fan, and the investment in a permanent cooling system rarely felt justified. Climate change is rewriting that calculation.
Europeans historically haven't used air conditioning because, until recently, summers were cool enough that it was an unnecessary expense. Instead, traditional European architecture relies on thick walls, cross-ventilation, and exterior shutters (like the German Rolladen) to keep homes naturally cool.
This means that any property used for short term lettings for a total of more than 90 nights in a calendar year must have planning permission from the local council in which it is based. People letting their property in breach of this law risk local councils taking planning enforcement action against them.
In the UK, air conditioning is most commonly referred to as "air con". While the full term "air conditioning" is widely understood, Brits typically shorten it to "air con" rather than the American "AC".
13 Things Not To Do When Visiting London
The 3-minute rule is a simple but important guideline: wait at least three minutes after turning your air conditioner off before turning it back on. That short pause gives the refrigerant pressure in the system time to equalize.
There is no single "best" AC brand, as the ideal choice depends on your region, budget, and whether you need whole-house central air or room units. Globally, industry leaders are ranked by their reliability, efficiency, and technological innovation.
No, keeping your AC set to 72°F typically does not save money. The U.S. Department of Energy (DOE) recommends setting your thermostat to 78°F in the summer for optimal efficiency. Every degree you raise your thermostat above 72°F can reduce your cooling costs by about 3% to 4%.
While individuals are born with LGBTQ identities within Amish communities, they cannot actively remain Amish while living openly. The culture does not allow for queer inclusion, and strict adherence to traditional gender roles means open LGBTQ members are typically excommunicated and shunned.
Many traditional Amish communities consider manufactured toilet paper an unnecessary luxury and use resource-saving alternatives instead. In outhouses, families often repurpose old newspapers, magazine pages, or catalogs (like the Sears and Roebuck catalog). To make the paper soft enough to use, they crumple it vigorously multiple times.
To say "hi" in Amish (Pennsylvania Dutch), simply say "guder daag" (pronounced goo-der dahg). It translates literally to "good day" and is the most common and appropriate way to greet someone at any time.
Despite its British popularity for a slightly less crude way to call the toilet, the word “loo” is actually derived from the French phrase 'guardez l'eau', meaning 'watch out for the water”.
The most popular UK slang for an attractive woman includes peng, leng, and fit. These terms are used similarly to "hot" or "gorgeous".
Over time, that evolved into “aircon” in more casual or regional usage, especially in Asia-Pacific countries influenced by British education or media systems. It's less frequently used in North America, where “AC,” “A/C,” or “air conditioner” are far more common.
Exploring on foot at night is in some ways safer as you're not coming up against these pinch points where you're at risk from the pickpockets when it's really busy. Mugging with threats is virtually unheard of. I take buses and walk all over at night and I never have a problem.
Legality in this context depends on the local restrictions in your area and your situation. For example, hosts renting out their properties in Scotland without a short let licence are probably breaking the law. If there are no regional laws or restrictions that apply then a house used for Airbnb should be legal.
Travelers are pivoting away from Airbnb for better deals, reliable customer service, and fewer hidden chore fees. Instead, most people are switching to direct hotel bookings, established rental sites like VRBO and Booking.com, or specialized alternatives depending on their travel style.
Many Amish people, though they don't use electricity, will use battery operated appliances and thus will use small fans and such. My grandma used to sit in the basement during the summer, during the hottest days. We didn't get ac until the mid 1980s, and still managed fine.
Europeans generally do not have air conditioning (AC) because historical climates rarely required it, and their older, masonry-built housing is explicitly designed to naturally keep interiors cool.
Most London apartments do not have air conditioning. It is estimated that fewer than 3% of residential properties in prime central London have built-in AC. Because UK homes were historically built to retain heat, locals generally rely on opening windows and using portable fans during the hottest summer days.
