Installing a new septic tank in your garden will often require both planning permission, building regulations approval and a septic tank permit.

The planning permission will ensure that the tank is installed in an appropriate location with information being provided to understand any potential implications for the surrounding environment and water.

Building regulations is required for the installation of a septic tank to ensure it meets the drainage and waste disposal standards set out in Approved Document H.

Where possible it is recommended that you connect to an existing public sewer instead of installing a septic tank, this reduces waste entering the waterways.

For more information visit our drains common project or contact your local planning authority.

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.

Adding a permanent wheelchair ramp for access to a home is likely to require planning permission as it will permanently change the external appearance of the front of the house. If the application is solely for improving disable access to the building then the planning application will be exempt from a planning fee.

If you live in a listed building, you will have to apply for listed building consent for any significant works, whether internal or external.

All permanent wheelchair ramps must comply with Approved Document M of the building regulations which specifies the gradient, width and surfaces which should be used.

Read Approved Document M: Access to and use of buildings.

Adding air conditioning to your home may be considered permitted development provided all the limits and conditions set out in legislation are met. The limits set out the function, size, placement and quantity of air conditioning units allowed.

The rights only apply if the system provides a heating function (including if it can provide both heating and cooling). If the system only offers a cooling function, then the rights do not apply and an application for planning permission will be required.

If your home is in a protected area such as a Conservation Area then permission will be required. If you live in a listed building then consent will be required.

The installation of air conditioning must comply with building regulations. It is advisable to contact an installer who can provide the necessary advice, preferably one who belongs to either the Microgeneration Certification Scheme or the relevant Competent Person Scheme.

The addition of a new external doorway will often fall under permitted development rights, meaning an application for planning permission is not required. This applies where the new doors are of similar appearance to those used elsewhere on the original building.

Permission may be required if your property is listed, you live in a conservation area oran Article 4 direction is in place. In these circumstances it is best to contact your local planning authority for more advice.

New external doorways which create a new or widened opening must comply with building regulations. A new structural opening will require a building regulations application.

The installation of a new door can be completed by a 'competent person' to ensure building regulation requirements are met. For more information on the competent person scheme and to find a registered person, visit the GOV.uk website.
