Significant changes to insulation and thermal elements would normally require building regulations approval. The extent to which this applies depends on the existing insulation and what it will be replaced with.

If the work is completed by a member of a competent persons scheme, then an application for approval will not be required.

Raising your garden level a small amount is likely to not require planning permission as it is likely to have minimal impact on the chances of flooding or overlooking your neighbours.

Increases of over 30cm may require planning permission as a significant change can impact drainage or your neighbours. If the changes are close to a boundary, you should consider whether it will overlook your neighbours or be intrusive.

You should contact your local planning authority to understand whether your proposed changes will require planning permission.

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.

Inserting new windows which look similar to those previously used in the house will often not require planning permission. Some rules apply to new additions, for example if they are on an upper-floor side elevation they must be obscure glazed and non-opening or more than 1.7 metres above the floor.

Installing a new bay window on the front elevation would require planning permission as it is classed as a forward extension.

If you live in a listed building or conservation area you should contact your local planning authority.

 Any new openings will have to comply with building regulations, this may impact thermal heat loss, structure, ventilation and fire safety.

You can use a member of a competent person scheme to complete any work, this will ensure that the work is completed in-line with regulations.
