Whether or not a static caravan can be kept on your property depends on how long it will be kept there for and what it’ll be used for. If the caravan becomes a new home on the property, will be rented out, or will stay in place for more than 28 days then permission if often needed.

If no material change of use occurs, and the caravan is only used for a purpose incidental to the enjoyment of the house then often no application for planning permission will be required. In this instance it may be classed as permitted development, as such it would have to adhere to limits and conditions set out for outbuildings.

If the property is in the curtilage of a listed building or in a conservation area you should contact your local planning authority.

‍

If the conservatory is not separated from the house by external quality walls, doors or windows, then it will lose its building regulations exempt status. As such it will be required to adhere to thermal efficiency rules and ventilation rules.

The new opening created from removal of the door will also need building regulations approval.

Merging two flats into one, commonly known as amalgamation is likely to require planning permission as it will impact the local planning authorities housing supply. The council’s views on this will vary from council to council. It is recommended that you contact your local planning authority to understand their position.

If you do not need to apply for planning permission then you can apply for a lawful development certificate to prove that the change is lawful.

Building regulations will be required if there are physical works taking place as part of the amalgamation, this may include removing walls or changing electrics. Visit the relevant common projects on our site for more information.

Your planning application must be made up of:

• The necessary plans of the site
• The required supporting documentation
• The completed form
• The correct fee.

The local planning authority will not be able to process your application unless the mandatory supporting documentation has been provided. You can also attach any other relevant documentation which you think will help the local authority determine the application.

What supporting documentation must be provided depends on the application type,  development type and local planning authority.

There are two levels of mandatory documents, national and local. If you’re applying online, the service will tell you what mandatory documentation you need to provide and allows you to attach the relevant documents. Most applications will require you to provide a location plan and a site plan.

In addition to the national list, your LPA may produce a list which details any specific documentation that is required to accompany the application. The requirements may vary according to the type of application, i.e. household, full, outline, etc. If you are applying online, this list is available from the supporting documents screen or your local planning authority’s website.

Inefficient windows and doors can significantly contribute to heat loss. Replacing single glazed windows by installing double glazing can cut heat loss through windows considerably. Double glazing works by trapping air between two panes of glass creating an insulating barrier that reduces heat loss, noise and condensation.  

‍

If you can't replace all the windows, why not choose the rooms that cost you the most to heat? Other options to reduce heat loss through windows include sealing gaps or using thermal blinds.

You don’t usually need planning permission for repairs, maintenance and minor improvements or replacing windows and doors that are of a similar appearance.

‍

Building regulations apply to replacement glazing, in terms of thermal performance, air supply, ventilation, safety and means of escape.
