Do I need permission?
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.

What do local authorities say?
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.

What help can I expect from my local conversation officer?
A Conservation Officer can provide helpful advice on the type and style of appropriate windows and can liaise with your glazing supplier to ensure an approved planning application.

Which Aluminium Windows & Doors have been approved in conservation areas?
Modern heritage aluminium systems, including the Alitherm Heritage windows and Alitherm Heritage (steel look) doors , are increasingly being approved for use in conservation areas due to their traditional appearance and improved thermal performance.
Alitherm Heritage slim and ultra-slim framed aluminium windows and doors are designed to replicate the elegant steel windows found in many older and period properties. They combine classic styling with modern benefits such as improved energy efficiency, security, durability, and low maintenance.
These heritage-style systems can be manufactured to match the windows of a bygone era commonly found in:
- Victorian homes
- Edwardian properties
- Art Deco buildings
- Traditional cottages and terraces
With slim sightlines, authentic detailing, and a wide range of heritage finishes, Alitherm Heritage windows and doors are often considered suitable for conservation areas where maintaining the character of the property is important.
Can I replace wood with thermally efficient aluminium?
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 which makes replica aluminium with it’s associated benefits a viable alternative.
Which conversation areas have aluminium replacement windows?
Alitherm Heritage 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)
- Ketton and Barnack near Stamford, Rutland, East Midlands
And Alitherm Heritage slim systems have already been approved for listed building projects by many councils which makes it likely although not guaranteed for approval in conservation areas. Councils include:
London Boroughs of Islington, Camden and Tower Hamlets, Watford Borough Council, Essex County Council and Leeds City Council as well as Cadw, the Welsh Government’s historic environment service.
What are the key features that enabled consent to be granted?
- 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.

What do Historic England say?
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.”
