Building Regulations vs Planning Permission for Plumbing Work in London

It is important to understand the distinction between planning permission and Building Regulations approval when dealing with plumbing and electrical work in London. Planning permission is concerned with the use, siting, and external appearance of development, and is granted by the local planning authority. Building Regulations approval is concerned with the technical standards of construction, including the safety and efficiency of building services installations, and is overseen by the Building Control service of the local authority or by a private approved inspector. Most domestic plumbing work in London does not require planning permission, but some categories of plumbing and heating work do require Building Regulations approval, and understanding which approval is required for which type of work avoids unnecessary applications and avoids the risk of carrying out notifiable work without the required approval.

The most common categories of plumbing work in London that require Building Regulations notification include the installation of a new boiler or hot water system, the installation of an unvented hot water cylinder, the provision of a new bathroom or shower room, and any extension or alteration to the building drainage system. These categories of work are notifiable under the Building Regulations whether or not they require planning permission. In contrast, planning permission may be required for works that affect the external appearance of the property, such as the installation of a boiler flue on a prominent elevation or in a conservation area, the installation of solar thermal panels, or the construction of an extension containing new plumbing facilities. Some works require both planning permission and Building Regulations approval, and both processes must be followed concurrently or sequentially as appropriate.

Using the Planning Portal for Building Regulations Submissions in London

The planning portal at planningportal.co.uk provides the interface for submitting both planning applications and Building Regulations notifications online for London local authority areas. For plumbing and electrical work that requires Building Regulations approval but does not require planning permission, the appropriate route is typically a building notice or a full plans application submitted to the Building Control service of the relevant London borough. A building notice is a simpler and faster route that does not require the submission of full drawings before work commences, and is appropriate for straightforward domestic plumbing and electrical projects where the scope is clear and the contractor is experienced in the relevant type of work. A full plans application requires the submission of detailed drawings and specifications before work commences, and provides greater certainty about compliance because the drawings are assessed before work begins rather than inspected at site visit stage.

For works carried out under the Competent Person Scheme, such as gas boiler installations by Gas Safe registered engineers and electrical work by NICEIC or NAPIT registered electricians, the installer self-certifies the work without requiring a separate Building Control submission. The installer notifies the relevant scheme operator, who notifies the local authority on behalf of the installer, and the local authority issues a completion certificate to the homeowner. This self-certification route is the normal route for the majority of domestic gas and electrical installation work in London, and means that most London homeowners do not need to interact with the planning portal for routine boiler replacements or electrical work. Prestige Engineers are Gas Safe registered and can self-certify boiler and heating installations across London, providing clients with the completion certificates required for property records and mortgage lender enquiries.
