Paragraph B.2 Conditions
Development is permitted by Class B subject to the following conditions—
in the case of any Class B(a) development consisting of or including the replacement of an existing electric line, compliance with any conditions contained in a planning permission relating to the height, design or position of the existing electric line which are capable of being applied to the replacement line;
in the case of any Class B(a) development consisting of or including the installation of a temporary electric line providing a diversion for an existing electric line, on the ending of the diversion or at the end of a period of 6 months from the completion of the installation (whichever is the sooner) the temporary electric line is removed and the land on which any operations have been carried out to install that line is restored as soon as reasonably practicable to its condition before the installation took place;
in the case of any Class B(a) development consisting of or including the installation or replacement at, or above ground level or under a highway used by vehicular traffic, of a chamber for housing apparatus where—
the chamber would exceed 29 cubic metres in capacity; and
any part of the chamber would be situated on article 2(3) land,
before beginning development the developer must apply to the local planning authority for a determination as to whether the prior approval of the local planning authority will be required with respect to the impact of the siting and the appearance of the chamber on that article 2(3) land;
in the case of any Class B(c) development, on the completion of that development, or at the end of a period of 6 months from the beginning of that development (whichever is the sooner) any plant or machinery installed is removed and the land is restored as soon as reasonably practicable to its condition before the development took place; and
in the case of any Class B(e) development, approval of details of the design and external appearance of the buildings must be obtained, before development is begun, from—
in Greater London or a metropolitan county, the local planning authority,
in a National Park, outside a metropolitan county, the county planning authority,
in any other case, the district planning authority.
In relation to an application under sub-paragraph (1)(ba), the application must be accompanied by—
a written description of the proposed development;
a plan indicating the site and showing the proposed development;
the developer’s contact address; and
the developer’s email address if the developer is content to receive communications electronically,
together with any fee required to be paid.
The local planning authority may refuse an application where, in the opinion of the authority—
the proposed development does not comply with; or
the developer has provided insufficient information to enable the authority to establish whether the proposed development complies with,
any conditions, limitations or restrictions specified in Class B applicable to the development in question.
Sub-paragraphs (5) and (7) do not apply where a local planning authority refuses an application under sub-paragraph (3) and for the purposes of section 78 of the Act (appeals) such a refusal is to be treated as a refusal of an application for approval.
The local planning authority must give notice of the proposed development—
by a site display in at least one place on or near the land to which the application relates for not less than 21 days of a notice which—
describes the proposed development;
provides the address of the proposed development; and
specifies the date by which the representations are to be received by the local planning authority; or
by serving a notice in that form on any adjoining owner or occupier.
The local planning authority may require the developer to submit such information as the authority may reasonably require in order to determine the application.
The local planning authority must, when determining an application—
take into account any representations made to them as a result of any notice given under sub-paragraph (5); and
have regard to the National Planning Policy Framework so far as relevant to the subject matter of the prior approval, as if the application were a planning application.
The development must not occur before the occurrence of one of the following—
the receipt by the applicant from the local planning authority of a written notice of their determination that such prior approval is not required;
the receipt by the applicant from the local planning authority of a written notice giving their prior approval; or
the expiry of 56 days following the date on which the application under sub-paragraph (2) was received by the local planning authority without the authority notifying the applicant as to whether prior approval is given or refused.
The development must be carried out—
where prior approval is required, in accordance with the details approved by the local planning authority;
where prior approval is not required, or where sub-paragraph (8)(c) applies, in accordance with the details provided in the application referred to in sub-paragraph (2),
unless the local planning authority and the developer otherwise agree in writing.
The local planning authority may grant prior approval unconditionally or subject to conditions reasonably related to the subject matter of the prior approval.
When computing the number of days in sub-paragraph (5)(a), any day which is a public holiday must be disregarded.
