Do you need planning permission to change windows on a listed building or in a conservation area?

If you own or manage a listed building, you are likely to be aware that planning often has to be more carefully considered.

Suppose you are looking to change windows on a listed building or in a conservation area. This is going to be one such situation that may require additional support.

Generally, it is preferred that windows in listed buildings or conservation areas are regularly maintained and repaired.

You may well be past that point and are looking for a full replacement. So what are your options?

Replace Like for Like

In the first instance, your easiest option in terms of planning would be to replace the existing windows in a ‘like-for-like’ fashion.

What does like for like mean?

You would need to ensure that the replacement windows are the same in terms of:

• materials
• glazing type
• pattern of glazing
• opening type
• timber moulding profiles
• general appearance
• glazing thickness

If you go ahead with the replacement you need to be aware that all of the above points need to be correct. Failure to replace the windows with a true like-for-like replacement could result in you receiving an enforcement notice from the local authority to reverse the works.

If you are unsure whether your like-for-like replacement windows are going to be sufficient enough to satisfy the local authority you should consult a heritage planning specialist.

Can I Upgrade the Windows?

If you are planning an upgrade to the windows including a move to double glazing for example.

You will be required to obtain listed building consent possibly in conjunction with planning permission.

This is explained on the Stratford District Council website. It is always worth referring to a local planning expert who will know the rules and regulations required by the local planning authority.

Historic England has advice that I recommend looking over on the subject of planning permission to change windows on a listed building or in a conservation area.

Our advice would be always to check with a local planning expert who has heritage planning experience if you are thinking of changing or upgrading the windows.

An expert will be able to advise on the best course of action should your listed building be subject to an Article 4 Direction.

What is an Article 4 Direction?

An article 4 direction is a direction under article 4 of the General Permitted Development Order which enables the Secretary of State or the local planning authority to withdraw specified permitted development rights across a defined area. An article 4 direction cannot be used to restrict changes between uses in the same use class of the Use Classes Order.

Keep Changes Sympathetic

I have found that planning departments will always be looking for any window replacement to be sympathetic and in keeping with the existing windows in place on the listed building.

You will want to ensure you are working with a tradesperson capable of performing any changes competently.

Additionally, it is often worth checking for any specific heritage training that a carpenter or glazer may have. Mistakes can be costly to rectify.
