Permitted Development Legislation - Oct. 1st 2008.
As of 1st October 2008 new legislation came into force which affects the permitted development rights of
domestic properties, most Councils have produced a set of guidance notes to assist you with these changes. Advice
that you have been given in the past on permitted development structures or alterations may no longer apply under
the current rules. Please check with each Local Authority Planning Dept. first as you may need clarification.
In certain cases, a dwelling can be enlarged, improved or altered without the need for
planning permission, subject to certain criteria (usually dimensional and siting). These rights are called
permitted development rights. The regulations on permitted development are very complicated and it is always
recommended that you seek advice from the Planning Section of your Local Authority on whether what you intend to do
requires permission or not.
Confirmation of Permitted Development
If you require formal confirmation of whether or not permission would be required for your proposed work, then
you may submit details of your proposals to your own local Authority Planning Dept. to allow them to take a view
but you may find resistance to this informal approach or you may be asked to pay a fee.
If no permission is required, you should retain the letter as proof of this but remember it will be full of
caveats and it is non binding on the part of the Council. A more formal approach would be to utilise the
Certificate of Lawful Development application route where the Councils decision is legally binding if the issue the
Certificate. There is a fee of half the current Planning fee for this service and it will take the Council between
6 and 8 weeks to respond.

Submitting the Details
You will also need to include a scaled drawing or sketch, with all the relevant measurements. Metric units
should be used throughout.
While the basic aim of permitted development rights is to exclude relatively minor development proposals from
planning controls, the need to control any significant impact of even minor development in protected or sensitive
environments means that the GPDO provides for some permitted development rights to be withdrawn or limited in
- in conservation areas, and certain other specified or designated areas such as National Parks, AONBs and
sites of archaeological interest;
- by conditions, exclusions and limitations applying to specific rights within each Part of Schedule 1 of the
- through Articles in the GPDO, including Article 4 and Article 6, which give the Department powers to remove
permitted development rights, and Article 3 which removes permitted development rights for development where an
Environmental Impact Assessment is required;
- in a few Parts of Schedule 1 of the GPDO, by requiring prior approval or notification of some of the
details of permitted development proposals to be provided and determined by the Planning Service.
Also, permitted development rights can be removed outside the GPDO through conditions attached to a previous
planning permission on the site.
