Normally planning permission is not required for installing a toilet in an existing area of the property as the change is only internal. If the toilet is part of a wider project such as an extension permission may be required.

If you live in a listed building, then listed building consent will be required for any major changes.

Building regulations will apply to the installation of a toilet in a property, these will cover areas such as ventilation, plumbing and drainage, and size.

Replacing the window within a bay window is treated the same as any other window. Meaning that the replacement of windows which have a similar appearance to those previously used would not require an application for planning permission.

Repairs, maintenance and minor improvements will also not require an application.

If you live in a listed building or a designated area then different rules may apply.

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.

Many homeowners choose to replace their traditional polycarbonate conservatory roof with a solid tiled roof for better thermal efficiency.

If the change significantly alters the structure or appearance of the roof, then planning permission may be required. Most alterations to roofs are considered permitted development, providing they meet the limits set out in legislation.

A new roof must comply with building regulations to ensure it is structurally safe, energy efficient and properly ventilated.
