Common Questions
There is no single legal definition of "habitable room", as its use and meaning are subject to context. Generally, a habitable room is a space in a building that is designed for people to live, sleep, or spend extended periods of time in, but does not include bath or toilet facilities, corridors or utility rooms.
Installing solar panels on your roof will often fall under permitted development rights, meaning an application for planning permission is not required provided certain limits and conditions are met.
The limits and conditions vary based on the type of roof you want to install the solar panels on and the location of the house. See the details below:
· On a pitched roof, panels should not be installed above the highest part of the roof (excluding the chimney) and should project no more than 200mm from the roof slope or wall surface.
· On a flat roof the highest part of the solar PV equipment cannot be more than 600mm higher than the highest part of the roof(excluding chimney).
· The panels must not be installed on a building that is within the grounds of a listed building or on a site designated as a scheduled monument.
· If your property is in a conservation area, or in a World Heritage Site, panels must not be fitted to a wall which fronts a highway.
As you have stated you’re in a conservation area, you must apply to the local authority for prior approval. This process includes submitting a form to the local planning authority which ensures that you meet the limits set out in legislation.
Forms relating to prior approval for mounting solar equipment can be submitted through the Planning Portal’s online application service and attract a fee of £240.

In many cases, yes. Converting a single residential property (Class C3) into a small House in Multiple Occupation (HMO) for up to six occupants can often be done under permitted development rights, specifically under Class L. This means that planning permission isn’t usually required.
However, if your property is located in an area covered by an Article 4 Direction, permitted development rights are removed, and you would need to apply for full planning permission to change the use from C3 (dwellinghouse) to C4 (HMO).

An improvement notice is a notice served by a local authority requiring a property owner to carry out specified works to bring a building into compliance with the legal standards. These are most commonly served to landlords to make a building safe.
The notice will specify what works should be completed and when it should begin and be completed by.
Failure to comply with an improvement notice is a criminal offence.
In many cases, you can extend a house without applying for planning permission by using what's known as permitted development rights, provided certain limits and conditions are met. However, if your plans go beyond these restrictions, you will likely need to apply for householder planning permission.
