Who are we and what do we do?

Welcome to CNC Building Control.

CNC provides the building control functions for the Local Authority areas of South Norfolk, King’s Lynn and West Norfolk, Fenland, Norwich City and Broadland. Building Control is a statutory requirement on the vast majority of building projects (including internal alterations and conversion works) irrespective of whether planning permission has been required or not.

It is the process of ensuring projects are completed in accordance with the Building Regulations and exists to ensure that the safety and well-being of any person is not compromised by changes or work that takes place.

In short, CNC are able to support you through your project from pre-planning and commencement through to project completion and issuing of certification.

We look forward to working with you.

2: New Requirement For Full Plans, Building Notices And Initial Notices For New Dwellings – Part R Infrastructure for electronic communications CONNECTIVITY PLAN

A connectivity plan is required ‘up front’ for both Full Plans & Building Notice applications, of new dwellings, to be valid.

For your convenience we have included on this page, 2 commonly used formats of a blank connectivity plan, which you can download and use.

Please submit a completed connectivity plan with your application.

This has been made a requirement by amending Regulation 13 (building notices) & Regulation 14 (full plans) to require a connectivity plan, or exemption, to be provided when the application is made.

It only applies to new build dwellings or new build buildings containing dwellings (eg flats).

Similarly, The Approved Inspector Regulations have been amended to say that the Initial Notice must include a connectivity plan (or exemption).

Advice from LABC and Government (DLUHC) is that failure to provide a connectivity plan, or details of exemption, is grounds for rejecting the Initial Notice under Ground 1 of the Approved Inspector Regulations.
