Permitted development is an allowance in which you can extend your property without having to achieve planning permission.

For a detached or semi-detached property an allowance of 70 cubic metres is allowed in total (only 50 cubic meters of the 70 are allowed for the loft)

And for a terrace or end of terrace an allowance of 50 cubic metres is allowed in total (only 40 cubic meters are allowed in the loft.)

e.g If you lived in a semi detached that already has a rear extension of around 30 cubic metres. This property would have 40 cubic metres left for the loft conversion. If the rear extension was only 18 cubic metres then you would still have the total amount of 50cu metres to use for the loft.

If you lived in a terrace house with an extension of 20 cubic metres then you would have 30 cubic metres left for the loft.

Please note that a listed building or a conservation area has it’s permitted development rights completely removed, and will always need planning permission.
