Local Listed Building Consent Order - Windows

Planning Consultation - Proposed Local Listed Building Consent Order

Local Listed Building Consent Order (the 'Order') in respect of certain works to windows in Grade II Listed Buildings within the Districts of Babergh and Mid Suffolk. (The Order is not intended to apply to Grade II* and or Grade I listed buildings.

The proposed Order relates to the:

  • installation of secondary glazing to historic windows
  • installation of double glazing, or energy saving glass, to windows which have previously been consented and introduced after listing - or which are already installed within a consented modern or post-listing extension

We hope that this Order gives a very clear signal to residents and businesses that we take the need to drive down carbon use seriously - and we are prepared to be proactive in achieving this.

This could encourage more building owners to act proactively too, rather than being deterred by the consent process.

We have published several documents as part of this consultation, which you can access further down on this webpage. The LLBCO - Works to Windows - Draft Order sets out more information, and a list of conditions that would need to be complied with. The accompanying Draft Statement of Reasons sets out our assessment of the likely effect of the proposed works on the special architectural or historic interest of the listed buildings to which the Order would relate - and a reasoned justification for making the Order.

The Order is proposed to last for five years at the outset and - if successful - may be extended.

Changes to windows in listed buildings is a sensitive issue, and we are particularly interested to hear whether the scope and conditions of the Order retain enough protection.

What is a Local Listed Building Consent Order?

Local Listed Building Consent Orders are a legal measure which allow local planning authorities to grant listed building consent for alterations to more than one listed building - including groups of listed buildings in all or part of the borough, or buildings or a particular description.

This is a proactive and blanket grant of listed building consent, which means that owners of the specified listed buildings will not have to make individual applications, but will be able to proceed with the works - provided that they comply with any conditions attached to the Order.
