WHEN A DPE IS REQUIRED
What applies to your property
The property has been altered
Moved partitions, rooms knocked through or a converted loft can all affect the figure. Check that the old measurement still reflects what you are selling.
CHECK THE EXEMPTIONS
Exclusions and special cases
- House outside a co-ownership arrangement
- Carrez law does not apply in the same way to a standalone house outside a co-ownership arrangement.
- Cellars, garages, parking spaces and small units
- These are covered by statutory exclusions. If units have been combined or altered, check the circumstances before applying the 8 m² threshold.
KEEP YOUR REPORT HANDY
Can you still use your report?
There is no fixed expiry date if the property remains unchanged. Measure again after works that affect the floor area.
Carrez private floor area and habitable floor area follow different calculation rules.
How to prepare for your visit
Gather before the visit
- Title deed and property unit identifiers.
- Plans and previous measurements.
- Details of any alterations since the last measurement.
During the visit
We measure the rooms and deduct areas excluded by Carrez rules. Existing plans help us prepare.
When you receive the report
Check the conclusions, the scope and limitations of the assessment, and any next steps. Keep the whole report, including its appendices.
Check which floor area your document gives
Total, habitable and Carrez floor areas are distinct. An old listing does not establish the figure you need.

PRACTICAL ANSWERS
FAQ
What you may want to know before the appointment
Does the area beneath a sloping ceiling count?
Only the part with a head height of at least 1.80 m counts, subject to the other deductions.
Does the measurement expire?
There is no fixed expiry under the rules. Check whether any changes to the property have affected the area.
Is an old floor plan enough to establish the area?
A plan helps us prepare. Tell us if the layout, partitions or units have changed, as the old floor area may no longer match what you are selling.
Which co-ownership documents should I have ready?
The co-ownership rules, property unit descriptions, plans and previous measurements, if available.
Can I use the figure from an old listing?
Check which type of measurement it used and whether the property has changed since.
