Moving from the US to the UK often feels like it should be straightforward. After all, both countries share a language, historical ties, and many surface-level similarities, from familiar shops to overlapping popular culture.
But when you start living in the UK, it quickly becomes clear that the cultural differences are deeper and more complex than many Americans expect.
These differences rarely manifest as dramatic shocks. Instead, they appear as small, persistent misunderstandings or discomforts, often invisible until they build up.
Recognising and preparing for these contrasts can make the transition much smoother and less emotionally taxing.
Drawing on the experience of expatriate coach, Amy Morton, who supports Americans settling into British life, this article explores the most common cultural challenges Americans face in the UK, and how to navigate them successfully.
Communication: Reserved doesn’t necessarily mean unfriendly
American culture places a high value on openness, friendliness, and verbal clarity. By contrast, British communication tends to be more reserved and indirect.
It’s common to express disagreement through understatement, and politeness can mask discomfort or disagreement rather than resolve it.
For newcomers used to more direct conversation styles, this subtlety can be confusing. Requests may be phrased as suggestions, and praise is often muted. Americans may find themselves wondering whether an invitation is genuine or whether feedback is more critical than it seems.
Those supporting Americans through their relocation often note that this style can lead to second-guessing and internal doubt, especially in the workplace or early social settings.
Suggestion: Don’t over-interpret politeness as rejection or vagueness as evasion. Try to learn to read between the lines and listen for tone and context, not just words. If you are in doubt, do not be afraid to ask for clarification.
Humour: Dry, understated and easily missed
British humour is often cited as one of the most noticeable cultural differences. It tends to be dry, understated, and laced with irony or self-deprecation. Sarcasm and “banter” are common, and jokes are often delivered with a straight face.
For Americans more accustomed to expressive or literal humour, this can be alienating at first. You may find yourself in a room where everyone is laughing except you, simply because the cues are unfamiliar.
Those with experience guiding American expats often point out that this cultural difference in humour is more than just style, it affects how people build rapport and express camaraderie.
Suggestion: If someone makes fun of you gently, it’s likely a sign of inclusion and affection, not mockery. Responding with humour, rather than defensiveness, helps bridge the gap.
Work Culture: Caution over confidence
The American professional environment often rewards assertiveness, clarity, and personal branding. In the UK, professional success is equally valued, but self-promotion is viewed with more suspicion. Confidence must be tempered with modesty, and performance is often expected to speak for itself.
In emails, for example, instructions are often phrased as polite questions or indirect suggestions. British colleagues may avoid confrontation or strong assertions, even when urgency or disagreement is present. This can feel inefficient or unclear to someone used to a more direct style.
People supporting expats frequently observe that Americans can feel professionally disassociated until they understand this different rhythm, especially in senior or leadership roles where tone management becomes essential.
Emotional Distance: Relationships develop more slowly in the UK
One of the most common surprises for Americans is the pace at which relationships develop. In the US, it’s common to form friendships quickly, sharing personal stories and building emotional rapport in early conversations.
In the UK, friendships tend to form more slowly and are often rooted in shared experience over time.
This slower progression can feel like rejection or coldness at first, especially when compounded by other cultural misunderstandings. It’s not unusual for Americans to report feeling socially isolated despite being surrounded by polite, seemingly friendly people.
Cultural coaches often emphasise that this emotional reserve is cultural, not personal. British people may simply take longer to open up and don’t necessarily see emotional openness as a prerequisite for connection.
Suggestion: Be patient. Focus on consistency and reliability. Relationships will deepen, but often over months, not weeks.
Class and social codes: Less obvious, more powerful
Class dynamics in the UK are more layered and less openly discussed than in the US, but they still influence many aspects of life, from professional opportunities to how people interpret your accent or choice of words.
While Americans often define class through income or education, the British model incorporates factors like school background, where someone grew up, family ties and even hobbies.
American accents may be interpreted in a range of ways depending on the setting, from "exotic" to "overconfident", and many expats are unaware of how these perceptions play out.
Professionals who support expats in the UK often describe class awareness as one of the hardest adjustments for Americans to recognise, precisely because it isn’t explicitly discussed. Class and cultural background can also be a source of unnecessary uncomfortable feelings for British people, so it discussions will often be accompanied by humour.
Suggestion: Observe first, speak second. Pay attention to how people present themselves and how social signals shift between settings.
Everyday differences: Cumulative culture shock
Many Americans underestimate the combined effect of small daily differences. For example:
- Queuing (lining up) is taken seriously. Skipping the line, even by accident, is frowned upon.
- School uniforms are expected in most schools, including public ones, although not at 6th form colleagues (16-19 year olds).
- Pubs are not just drinking establishments—they’re key social spaces and often the default for casual business catch-ups.
- Public transport is more common than driving in urban areas, but often less punctual than Americans expect (and British people hope).
- Bank holidays and holidays in general, are treated as sacred time off and productivity levels will shift through different holiday seasons.
Over time, these differences can contribute to a kind of low-level fatigue. It’s not the big decisions, like housing or visas, that wear people down, but the dozens of tiny adjustments required just to function smoothly and can lead to loneliness and homesickness if misunderstood.
Coaches frequently describe this as “cultural friction”. not enough to stop progress, but enough to create emotional drag.
Suggestion: Try to accept the daily differences as part of the experience. The quicker you stop expecting things to be the same, the easier adaptation becomes.
Emotional adaptation: Expect a dip
Almost all international relocations involve some degree of culture shock. For Americans moving to the UK, this often happens later than expected, typically around the 6 to 9-month mark, when the novelty wears off and the emotional toll of adaptation becomes clearer.
This dip is normal but also avoidable and/or manageable if people prepare mentally for the cultural shift as well as the logistical move.
Suggestion: Look to build in emotional awareness before the move. Have someone you can talk to, whether a coach, community, or mentor, who understands the expat experience and can help you and your family settle.
Living in the UK is the same as in the US… until it isn't
Moving from the US to the UK is one of the easier international transitions linguistically and legally.
But culturally, it’s often more challenging than Americans expect. The similarities can create a false sense of security, masking the depth of social, professional, and emotional differences.
The good news is that these differences are manageable. With awareness, curiosity and the right support, American expats can settle in well and even thrive in British life. The key is to expect difference rather than difficulty and to allow yourself time to adjust without judgment.
