Past Perfect Continuous
Learn how to form the past perfect continuous, and how it emphasises duration leading up to another point in the past.
Duration leading up to a past point
This tense keeps the focus on how long something had continued.
The past perfect continuous emphasises how long an action had been continuing before another point in the past. It is formed with had been, plus the -ing form.
In She had been working there for years before she retired., had been working emphasises the length of time this job had continued, leading up to her retirement.
This lesson covers how the past perfect continuous is formed, and how it differs from the past perfect.
Before you begin
This is one of four topics on past tenses.
This lesson focuses on the past perfect continuous specifically. Past tenses as a whole includes three other topics, each covered in its own lesson.
If you would like an overview of past tenses in general, begin with the Past Tenses page.
The central idea
Duration and completion are two different things to emphasise.
Compare the past perfect continuous with the past perfect, describing related but distinct ideas.
01
Past perfect continuous
She had been writing all week before the deadline.
02
Past perfect
She had written three chapters before the deadline.
The useful question is: is duration or result the point of this sentence?
The first sentence emphasises how long she had been writing. The second emphasises the result: three completed chapters.
Forming the past perfect continuous
Had been, plus the -ing form, for every subject.
I had been working. She had been working. They had been working.
Unlike the present perfect continuous, this form uses only had, with no change across different subjects.
What the past perfect continuous describes
Two related situations call for this tense.
Duration before another past point
She had been living there for five years before she moved.
The cause behind a past situation, shown through evidence
His hands were covered in paint; he had been painting all afternoon.
The activity itself may have just ended, but its effects were still visible at that past moment.
For and since
These words work the same way as they do in the present perfect.
For marks a length of time, and since marks a starting point, exactly as they do in the present perfect. This is covered in full detail in its own lesson.
Stative verbs and this tense
The same verbs that avoid other continuous forms avoid this one too.
Verbs like know, want and believe describe a state rather than an action, and stay out of continuous forms here as well. She had known him for years. is preferred over She had been knowing him for years.
A useful decision guide
Ask whether duration or result is the point.
01
Is the length of time the main point?
If so, the past perfect continuous usually fits.
02
Is a completed result the main point instead?
If so, the past perfect usually fits better.
03
Is the verb a stative verb?
If so, avoid the continuous form here as well.
04
Are both had and been present?
Both pieces are required to complete this tense.
Common mistakes
A missing been is the most frequent slip.
Been is not left out of this tense.
Not: She had working there for years before she retired.
Correct: She had been working there for years before she retired.
Had, not has, is used here, regardless of the subject.
Not: She has been working there for years before she retired.
Correct: She had been working there for years before she retired.
A stative verb is not put into this continuous form.
Not: She had been knowing him for years.
Correct: She had known him for years.

Quick review
The past perfect continuous keeps duration at the center of the sentence.
The past perfect continuous is formed with had been, plus the -ing form, unchanged across every subject.
It emphasises duration before another past point, or explains a past situation through visible evidence.
The past perfect, in contrast, often emphasises a completed result.
Stative verbs avoid this continuous form, just as they do in every other continuous tense.
Remember
Ask whether duration is the point, or the outcome is.
When how long something had been happening matters more than what it had produced, the past perfect continuous is usually the better fit.
