Provided (That), Providing & As Long As
Learn how “provided,” “providing” and “as long as” introduce a required condition, often used for permission or agreement.
On one condition
These phrases state a condition that must be met.
Provided, providing and as long as introduce a condition that must be satisfied for something to be allowed or to remain true. All three generally work in place of if, adding a stronger sense that the condition is a requirement.
In the sentence You can go, provided you finish your homework first., permission to go depends entirely on finishing the homework first.
These phrases are especially common when granting permission, making an agreement, or stating a rule that must be followed.
Before you begin
These phrases are among several words that can introduce a condition.
This lesson focuses on “provided,” “providing” and “as long as” specifically. For an introduction to conditional sentences as a whole, and how the parts of a conditional sentence are identified, begin with Understanding Conditionals.
Three ways to say the same thing
Provided, providing and as long as are largely interchangeable.
Compare the same idea expressed with each phrase.
01
Provided (That)
Slightly formal; often used in writing and agreements.
You can go, provided that you finish your homework.
02
Providing
Works the same way, with or without “that.”
You can go, providing you finish your homework.
As long as, more common in everyday speech
You can go, as long as you finish your homework.
As long as expresses the same required condition, and is generally more common in relaxed, spoken English than provided or providing.
The pattern
These phrases usually pair with the present simple, like an if-clause.
A future condition
You can borrow the car, provided you drive carefully.
As with an if-clause, the clause introduced by these phrases uses the present simple to refer to a future condition, not will.
An ongoing agreement
You can stay here as long as you like.
As long as can also describe a condition that continues for as much time as something else continues, rather than a single future event.
Word order and punctuation
The condition clause can come first or second, but punctuation changes.
Condition clause first: use a comma
As long as you finish your homework, you can go.
Condition clause second: no comma
You can go as long as you finish your homework.
Both orders are correct and mean the same thing, following the same punctuation rule as sentences with “if.”
A useful decision guide
Ask how strongly the condition is a requirement.
01
Is the condition close to a rule that must be met?
Provided, providing or as long as fit better than a plain “if.”
02
Is the setting formal, such as writing or an agreement?
Provided (that) or providing suit the tone better than as long as.
03
Is the setting relaxed, everyday speech?
As long as is the more common, natural choice.
Common mistakes
Do not use “will” in the condition clause.
Using will in the condition clause.
Not: You can go, provided you will finish your homework.
Correct: You can go, provided you finish your homework.
The clause follows the same rule as an if-clause, keeping “will” out of it.
Confusing “as long as” with “as soon as.”
Not: As soon as you finish your homework, you can go, meaning “on the condition that.”
Correct: As long as you finish your homework, you can go.
As soon as refers to timing, meaning “immediately after,” while as long as states a required condition.
Adding “that” after “providing” and treating it as required.
Both correct: Providing you finish your homework, you can go.
Both correct: Providing that you finish your homework, you can go.
“That” is optional after “provided” and “providing,” and can be included or left out without changing the meaning.
Check your understanding
Are these phrases used correctly?
Choose the correct answer for each sentence.
Which sentence correctly uses “provided”?

“You can stay here as long as you like.” What is being described here?
✅ Exactly! “As long as” can describe an ongoing condition, not just a single event.
❎ Not quite. Think about the duration being described in this sentence.
Choose the best explanation
Select the sentence that explains these phrases correctly.
Why do “provided,” “providing” and “as long as” suit permission and agreement so well?
✅ Exactly! The stronger sense of requirement is what distinguishes these phrases from a plain “if.”
❎ Not quite. Think about the tone these phrases add, compared with “if.”
Why does “as long as” sometimes describe duration, rather than a single event?
✅ Exactly! This use draws on the literal comparison of durations built into the phrase.
❎ Not quite. Think about what “as long as” is literally comparing.
Why is “that” optional after “provided” and “providing”?
✅ Exactly! “Provided you finish” and “provided that you finish” mean exactly the same thing.
❎ Not quite. Compare the meaning of both versions closely.
Try it another way
Complete each sentence with the correct word or form.
Type the missing word shown in brackets.
✅ Exactly! “Provided” states the required condition here.
❎ Not quite. Think of the word often used for permission or agreement.
✅ Exactly! The condition clause uses the present simple, matching an if-clause.
❎ Not quite. Use the present simple form of “drive.”

Edit the sentence
Rewrite each sentence with the correct form.
Use the note in brackets to decide what needs to change.
You can go, provided you will finish your homework. (correct the condition clause)
✅ Exactly! “Will” does not belong in the condition clause.
❎ Not quite. Replace “will finish” with the present simple “finish.”
You can borrow the car, provided that you drive carefully. (rewrite using “as long as,” more suited to everyday speech)
✅ Exactly! “As long as” expresses the same required condition, in a more everyday tone.
❎ Not quite. Replace “provided that” with “as long as.”
You can go, providing you finish your homework. (rewrite with the condition clause first)
✅ Exactly! Moving the condition clause first needs a comma before the main clause.
❎ Not quite. Move the condition clause to the front, and add a comma.
Quick review
These three phrases all state a required condition.
Provided (that), providing and as long as introduce a condition that must be met, often for permission or agreement.
“That” is optional after “provided” and “providing.”
As long as is the most common choice in everyday speech, and can also describe duration.
The condition clause uses the present simple for a future condition, avoiding “will,” just as an if-clause does.
A condition clause first needs a comma; a condition clause second does not.
Remember
Ask whether the condition reads as a firm requirement.
When a plain “if” feels too mild for the situation, “provided,” “providing” or “as long as” can add the sense of a rule or agreement that must be honoured, while still following the same verb patterns as an ordinary conditional sentence.
