Once you submit your application it will be considered by the local planning authority. The Planning Portal does not have access to the application once it is submitted.
You will need to contact your local planning authority to check on the progress of any submitted application. Many authorities now let you track the progress of applications on their own council websites.
Your local authority’s contact details and website address can be found by using our local authority search.
In many circumstances, rules known as ‘permitted development’ rights allow you to extend a house without needing to apply for planning permission, providing specific limitations and conditions are met. 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.

If you do not seek planning permission, build without it when it applies, or do not meet specified conditions of a planning permission, this is known as a planning breach.
Your local planning authority can serve an enforcement notice on you when they consider you have broken planning rules. You may be given the opportunity to apply retrospectively, or be required to remove a building or structure, or alter it to make it acceptable.
There are different planning fees for England and Wales, and many different application types depending on the work being carried out.
You can use the Planning Portal's fee calculator to work out fees for different kinds of proposal.

While every effort has been taken to ensure that the fee has been calculated correctly, the determination of whether a planning fee is correct is the responsibility of the relevant local planning authority, who will check the fee is correct when the application is submitted and validated.
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).

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.
