If you want to exceed these limits and conditions, then it is likely that an application for householder planning permission will be required.
You can find information about the limits and conditions, prior approval and the building regulations on the Planning Portal by using the links below.

Firewalls provide protection against fires spread which may occur to neighbouring properties. Building regulations ensure that modern homes are fitted with firewalls as well as other fire safety measures such as adequate fire escapes and alarm systems.
Older homes may not have a firewall installed in the loft, especially in homes with shared loft spaces. There is no requirement to retrospectively install a firewall, but it should be considered to improve the safety of your home and those living in it.
As an adjoining loft firewall is a party wall, you will need to talk to your neighbour to discuss the work.
In most cases neither planning permission nor building control approval are required for replacing grass with artificial grass. If you live in a protected areas such as a conservation area, or listed building, it is best practice to contact your local planning authority to check whether any consents are required.

You typically will not need planning permission to install a hot tub in your garden, as it is classed as an outbuilding and within the permitted development rights in terms of size and portability. However, you may need planning permission if you live in a listed building or conservation area, you should check first with your local authority.
The hot tub will need to adhere to the building regulations in terms of safe and adequate electrical installation by a registered competent person. Find out more about using a registered competent person.
Also, if the hot tub is placed within a building such as a large shed-style structure, there will be separate planning and building control limitations on that structure.
A designated area is situated within a World Heritage Site, Conservation Area, Site of Special Scientific Interest, National Park, or an Area of Outstanding Natural Beauty, the area is protected by law due to its architectural or historic interest or landscape.
Due to this protection, there will be further limits on what you can do to your property if it is within such an area, for example building an extension, changes to the roof, or work to trees. Restrictions will be put in place and permitted development rights will not apply.
If you live in a designated area, you must seek advice from your local planning authority before starting any work.
