In general you do not need planning permission to replace windows in a conversation area such as within the Yorkshire Dales. However, it is strongly advisable to consult your local conservation officer.
Permission is required if the area has been designated an article 4 directive. This prevents window and door replacement without planning permission.
Typically local authorities (e.g. Yorkshire East Riding) encourage:
“Like for like repair or replacement, although new and innovative designs which harmonise with the original building may be acceptable in appropriate locations. There will be a need for the use of high quality materials and design.”
This means that openings which were designed for sash windows should contain replacement sash windows and openings designed for side hung casement windows should contain side hung casement windows. The replacement should replicate original detailing as far as possible and be of high lasting quality.
A Conservation Officer can provide advice on the type and style of appropriate windows and may provide detailed drawing of four panel doors, one- and two-pane sash windows and double glazed sash windows free of charge.

Approved Aluminium Replacement Windows
For Conservation Areas
Historically, when local authorities have encouraged or stipulated using traditional materials i.e. wood frames which allows for thin frames to support light, thin glazing. Modern glazing tends to be thick and heavy requiring thick frames to support it. However, recent developments in aluminium now mean that this is no longer the case.
Slim and ultra slim framed thermally efficient aluminium windows are now available. These can be made to match the windows of a bygone era found in many homes in conservation areas.
Alitherm Heritage slim windows have been used to replace windows in conservation areas such as:
- The Yorkshire Dales National Park
- North York Moors National Park
- Addingham, Baildon, Ilkley, Menston, Harrogate and Knaresborough (to name but a few)
Consent was granted because:
- Alitherm Heritage profiles have been developed to precisely match the slim profiles of traditional steel windows.
- Window furniture is synonymous with Victorian and Art Deco styles – including ‘Monkey Tail’ and ‘Bulb’ options.
- Alchemy anodising offers eight colour matches, including shades of gold, bronze, silver, grey and black, and combines the unique style and aesthetics of traditional anodising.
Alitherm Heritage is a versatile high quality window suited for use in conservation areas. Marlin Windows work closely with Conservation Officers to ensure window replacement is hassle free.

According to Historic England (formally English Heritage) “window frames and glazing patterns which complement the building's style, will be encouraged."
"Quality is enduring, even though taste and fashion may change. The eye appreciates the aesthetic qualities of a place such as its scale, composition, silhouette, and proportions, and tells us whether the intervention fits comfortably in its context. Achieving quality always depends on the skill of the designer. The choice of appropriate materials, and the craftsmanship applied to their use, is particularly crucial to both durability and to maintaining the specific character of places."
Attention to detail and the quality of craftsmanship and finish is why those who need to replace windows in conservation areas choose Marlin Windows.
