Have you ever typed “enquiries” and wondered whether it should actually be “inquiries”? You are not alone. Both spellings are correct, but the version you should use depends mainly on the variety of English you are writing in and, in British English, sometimes on the meaning.
In simple terms, enquiries is strongly associated with British English, while inquiries is the standard form in American English. British English can also use inquiries, particularly when referring to a formal investigation. Cambridge lists enquiry as a UK form of inquiry, while Oxford notes that British writers may distinguish between the two according to meaning.
So, which spelling should you choose?
Use “enquiries” for general questions or requests when writing in traditional British English. Use “inquiries” for American English and for formal investigations in many British contexts.
Let’s break down the difference with clear examples so you can choose confidently every time.

Enquiries or Inquiries: Which Spelling Is Correct?
Both enquiries and inquiries are legitimate English spellings. The main difference is regional usage rather than one being simply “right” and the other “wrong.”
Cambridge defines enquiry as a UK spelling related to inquiry, while Merriam-Webster describes enquiry as a chiefly British spelling.
Is “Enquiries” Correct in British English?
Yes. Enquiries is a standard British English plural spelling of enquiry.
British businesses, schools, hotels, and public-facing organizations commonly use it when talking about general questions or requests for information.
For example:
- Please send all enquiries to our customer service team.
- We received several enquiries about the new course.
- The hotel is handling booking enquiries by email.
- For further enquiries, please contact the office.
Cambridge specifically identifies enquiry as a UK form of inquiry.
Is “Inquiries” Correct in American English?
Yes. Inquiries is the normal American English spelling.
American English generally uses inquiry for both general requests for information and formal investigations.
For example:
- We received several customer inquiries.
- Please direct all media inquiries to the communications department.
- I made several inquiries about the price.
- The committee launched an inquiry into the issue.
Cambridge’s American Dictionary uses inquiry and inquiries for requests for information as well as official investigations.
Quick Answer
| Meaning/Context | British English | American English |
|---|---|---|
| General question | enquiry/enquiries | inquiry/inquiries |
| Customer request | enquiry/enquiries | inquiry/inquiries |
| Request for information | enquiry/enquiries | inquiry/inquiries |
| Formal investigation | inquiry/inquiries | inquiry/inquiries |
| Most familiar spelling in the US | inquiries | |
| Common traditional UK spelling | enquiries |
The easiest rule is: UK general questions → enquiries; US English → inquiries.
Enquiries vs Inquiries in UK and US English
The biggest difference becomes clear when you compare regional English varieties. American English generally uses inquiry/inquiries regardless of whether the subject is a simple question or a serious investigation. British English, however, has traditionally maintained a distinction between enquiry and inquiry in some contexts.
British English: Enquiries for General Questions
In everyday British English, enquiries often refers to ordinary requests for information.
For example:
We welcome all customer enquiries.
This sounds completely natural in British English.
Other examples include:
- Sales enquiries are handled by our London office.
- Please contact reception with any enquiries.
- We have received several enquiries about the event.
- All student enquiries should be submitted online.
Oxford notes that British English sometimes uses enquiry for a general request for information and inquiry for a formal investigation. However, it also explains that either spelling can be used in either sense.

American English: Inquiries for Both Meanings
American English normally uses inquiries for both everyday questions and official investigations.
For example:
Please direct all customer inquiries to our support team.
You would also write:
The committee conducted an inquiry into the incident.
This makes inquiries the safest choice when your content is specifically intended for a US audience.
Why the Difference Matters in Professional Writing
Spelling consistency matters when writing websites, emails, reports, product pages, and business documents.
Imagine a UK hotel website that says:
For booking inquiries, contact our reservations team.
The sentence is understandable and not necessarily incorrect, but booking enquiries may feel more naturally British to many UK readers.
On an American website, however:
For booking inquiries, contact our reservations team.
is the expected form.
Therefore, the best spelling is usually determined by your audience, not by a universal rule that says one version is correct and the other is wrong.
Enquiries vs Inquiries: Meaning and Usage
Although the spelling changes, the underlying meaning is closely related. Both words can describe asking for information, seeking an answer, or conducting an investigation.
What Does “Enquiries” Mean?
Enquiries is the plural of enquiry. It generally means questions, requests for information, or requests for clarification, particularly in British English.
Examples:
- We received ten enquiries about the course.
- The office handles customer enquiries.
- I made several enquiries about the property.
- Please send your enquiries by email.
The word is especially common in customer service and general information contexts in British English.
What Does “Inquiries” Mean?
Inquiries is the plural of inquiry.
It can mean requests for information or formal investigations.
Examples:
- We received hundreds of customer inquiries.
- She made several inquiries about the position.
- The authorities launched inquiries into the matter.
- The company responded to media inquiries.
Cambridge defines an inquiry as the process of asking a question and also as an official process intended to discover facts.

Enquiry vs Inquiry: Singular and Plural Forms
A useful way to remember the spelling is to start with the singular form:
- enquiry → enquiries
- inquiry → inquiries
Notice that the plural changes -y to -ies.
So:
❌ enquieries
❌ inquries
❌ enquires when you mean the noun
Correct:
✅ enquiries
✅ inquiries
For example:
We received several enquiries yesterday.
or:
We received several inquiries yesterday.
When Should You Use Enquiries or Inquiries?
Choosing between the two becomes much easier when you consider your audience and the context.
Use “Enquiries” When Writing for a UK Audience
If your website, email, brochure, or document follows British English and you are talking about general questions, enquiries is a natural choice.
Examples:
- General enquiries
- Customer enquiries
- Sales enquiries
- Booking enquiries
- Student enquiries
- Further enquiries
For example:
For further enquiries, please contact our support team.
This is a natural British English sentence.
Use “Inquiries” for American English
For an American audience, choose inquiries.
Examples:
- Customer inquiries
- Media inquiries
- Sales inquiries
- General inquiries
- Product inquiries
For example:
Please send all product inquiries to our sales department.
This matches normal American English usage.
Use “Inquiry” for Formal Investigations
When referring to an official investigation, inquiry is widely used in both British and American English.
Examples:
- A public inquiry was launched.
- The committee conducted an inquiry.
- The government announced an inquiry into the incident.
- An independent inquiry will examine the allegations.
This distinction is still visible in modern British style guidance. For example, Merton Council’s style guide recommends enquiry for a small-scale question and inquiry for a large-scale investigation.
Enquiries or Inquiries: A Simple Decision Guide
If you are still unsure, use this quick checklist.
Step 1: Identify Your Audience
Ask yourself:
Am I writing for British or American readers?
- UK → usually enquiries for general questions
- US → inquiries
- International → choose one style and stay consistent
Step 2: Check the Meaning
Are you talking about a simple request for information?
Please contact us with any enquiries.
For British English, this is a natural choice.
Are you talking about an official investigation?
The government launched an inquiry.
Use inquiry.

Step 3: Keep Your Style Consistent
Don’t switch randomly between forms.
For example, if a UK website uses:
Customer enquiries
it should generally avoid switching elsewhere to:
Customer inquiries
unless there is a deliberate reason.
Consistency makes professional writing easier to read and gives your content a more polished appearance.
2025–2026 Usage Snapshot: What Current Sources Show
There is an important point about statistics: there is no widely accepted 2025–2026 statistic giving a precise percentage split between “enquiries” and “inquiries” across all English writing. Search-volume estimates or isolated website counts would not provide a reliable measure of worldwide language usage.
However, current authoritative references provide useful evidence about how the spellings are treated today.
Cambridge’s current dictionary: Cambridge identifies enquiry as a UK form of inquiry and gives inquiries as the business-English plural, while its American entry uses inquiry as the standard form.
Oxford’s current dictionary: Oxford states that enquiry is especially British English and notes the traditional British distinction between general requests and formal investigations, while acknowledging that either spelling can occur in either meaning.
2026 public-sector style guidance: A February 2026 Australian government plain-language guide recommends using inquiry rather than enquiry in all contexts, noting that inquiry is increasingly used broadly. This demonstrates that usage preferences can also change within English-speaking regions over time.
2025 UK evidence: UK Intellectual Property Office records from 2025 show that both Business inquiries and Business Enquiries appear in official trademark classifications, illustrating that both forms remain visible in contemporary UK professional usage.
The takeaway is more useful than an artificial percentage: regional style and context remain the best guides.
Real-Life Example: Choosing the Right Spelling for a Business Website
Imagine a company called Greenfield Travel that serves customers in both the UK and the United States. Its marketing team is preparing two versions of its customer-service page.
The UK version says:
“If you have any booking enquiries, please contact our reservations team. Our team aims to respond to all enquiries within one business day.”
This sounds natural for a British audience because enquiries is commonly used for general customer questions.
The US version says:
“If you have any booking inquiries, please contact our reservations team. Our team aims to respond to all inquiries within one business day.”
Here, inquiries is the natural American spelling.
Now imagine the company announces an official investigation after a serious operational problem. The wording changes:
“An independent inquiry will examine what happened and make recommendations.”
Notice something important: the company did not need to use enquiries simply because its UK website uses British English. The context has changed from ordinary customer questions to a formal investigation.
This is why relying on a simple rule such as “enquiry is British and inquiry is American” can sometimes be too limited. Audience matters, but meaning matters too. Oxford specifically recognizes this traditional British distinction, while also noting that the two spellings can overlap.

For content creators, the practical lesson is simple: decide which English variety your website follows, understand the context of the sentence, and then apply the spelling consistently. That approach works better than trying to memorize dozens of isolated examples.
Common Mistakes With Enquiries and Inquiries
The words are easy to confuse because their pronunciation and meanings are almost identical.
Mistake 1: Treating One Spelling as Always Wrong
It is incorrect to assume that enquiries is simply a misspelling of inquiries.
Both are established forms. Merriam-Webster identifies enquiry as a chiefly British spelling, while Cambridge treats it as a UK form of inquiry.
Mistake 2: Mixing UK and US Styles
A page might begin with:
Customer enquiries are welcome.
and later say:
Please submit all customer inquiries online.
Neither word is inherently wrong, but the inconsistent style can look careless.
Choose one regional style and stick with it.
Mistake 3: Misspelling the Plural
Remember:
enquiry → enquiries
inquiry → inquiries
Do not write:
❌ enquieries
❌ inquries
Mistake 4: Assuming “Inquiry” Always Means an Investigation
In American English, inquiry can simply mean a request for information.
For example:
I sent an inquiry about the price.
There is no formal investigation involved.
Cambridge explicitly gives “the process of asking a question” as one meaning of inquiry.
