The designation and day-to-day management of conservation areas is the sole responsibility of Local Authorities, which produce their own local guidance and policies. Historic Environment Scotland is not producing planning guidelines for conservation areas.
The Scottish Government’s policies on alteration or change in the historic environment are set out in Scottish Planning Policy (SPP). Historic Environment Scotland's publications in the series, Managing Change in the Historic Environment, aim to explain that policy clearly in the context of best practices for traditional buildings.
On 27 February 2017, Historic Environment Scotland published a consultation on its Managing Change in the Historic Environment guidance relating to windows. This provides best practice guidance in relation to windows of all kinds in historic buildings.
