Important Notes for Applicants:
This form is optional, as the legislation does not require that you submit a form. However, this form has been designed to help ensure
that you provide the LPA with the information required by the legislation.
From the date when the LPA receives your notification (with the information required by the legislation), the LPA has a period of 42
days to notify you of one of the following outcomes:
 Prior approval is not required.
 Prior approval is given.
 Prior approval is refused.
If prior approval is not required, or if prior approval is given, or if the LPA fails to notify you of one of the above outcomes within 42
days, then this will indicate that the proposed development would comply with condition A.4 of Part 1 Class A of the GPDO 1995 (as
amended). It’s important to note that this won’t indicate whether or not the proposed development would comply with any of the
other limitations or conditions of Part 1 Class A. After you receive the decision (or if the LPA fails to notify you within 42 days), if you
want confirmation that the proposed development would be lawful (e.g. on the basis that it would comply with all of the limitations
and conditions of Part 1 Class A), then you should submit an (optional) application to the LPA for a Lawful Development Certificate
(LDC).
If prior approval is refused, then this will indicate that the proposed development would not comply with condition A.4 of Part 1 Class
A of the GPDO 1995 (as amended). It’s important to note that this won’t indicate whether or not the proposed development would
comply with any of the other limitations or conditions of Part 1 Class A. After you receive the decision, you will have the right to submit
an appeal to the Planning Inspectorate.
It’s important to note that if an objection is received from any adjoining premises, then the LPA is required to consider the impact of
the proposed development on the amenity of all adjoining premises. If the LPA considers that the information you’ve submitted is
insufficient for them to be able to assess this impact, then they may ask you to submit further information, or they may refuse prior
approval on the basis that the information you’ve submitted fails to demonstrate that the impact would be acceptable. To reduce the
likeliness of the latter situation, you may wish to submit further information at this initial stage. In particular, please consider the
following:
 Although the legislation requires you to state the “maximum height” and the “height of the eaves” of the extension, this
information by itself doesn’t necessarily establish what would be the height of the part of the extension nearest to the
adjoining premises. For example, would the extension have a hipped roof or a mono-pitched roof, and if the latter what would
be its orientation? Furthermore, would the roof of the extension have raised parapet walls, and if so what would be their
height? You may, therefore, wish to submit further information at this initial stage about the height and design of the roof of
the extension.
 As advised by the DCLG “Permitted development for householders - Technical Guidance” document, “height” is measured from
the highest part of the surface of the natural ground immediately adjacent to the proposed development. If the natural ground
level adjacent to the proposed development is not uniform, then you may wish to submit further information at this initial stage
to demonstrate that the figures that you have stated for the “maximum height” and the “height of the eaves” of the extension are
based upon the correct interpretation of the term “height”.
 To enable the impact of the proposed development on the privacy and overlooking of adjoining premises to be assessed, you
may wish to submit further information at this initial stage about any windows and other areas of glazing, including their position
and size, whether they would be clear glazed or obscure-glazed, and whether they would be opening or non-opening.
 To enable the owners and occupiers of the adjoining premises to know what materials would be used for the proposed
development, you may wish to submit further information at this initial stage about materials.
After you submit your notification to the LPA, if you do not receive any correspondence within 2 weeks, then you should contact the
LPA to check whether or not they’ve received your notification, in case it has been lost in the post. Similarly, if you do not receive a
written notice from the LPA (i.e. notifying you of the outcome) within 6 weeks from the date that they receive your notification, then
you should contact the LPA to check whether or not they’ve issued a written notice, in case it has been lost in the post.
