Just to add our experience to the conversation—as self-builders, we should have been exempt from the Community Infrastructure Levy (CIL). We were granted CIL exemption and submitted our commencement notice before starting any work, as required. However, we made a small revision to the original plans (adding an extra bedroom in the loft) and submitted this as a minor amendment to the existing planning application.
Since we already had planning approval, we began digging the footings. To our surprise, we then received a CIL demand that was payable immediately. Unbeknown to us, the Council had treated the minor amendment as a new planning application. This meant we were required to submit a second commencement notice, even though it was clearly related to the original, CIL-exempt approval.
The Council sent someone to the site to take photos proving work had started, and we were forced to borrow funds to pay the CIL charge in full.
We know we are not alone—many self-builders, and even homeowners extending their properties or building annexes, have been caught out by this simple paperwork oversight mainly between 2010 to 2020. In some cases, people have received CIL bills totaling over £100,000—all because they didn’t submit a commencement notice, often through no fault of their own.
What’s most frustrating is that some Councils provided no warning or guidance on how serious the financial implications can be. If we’d known we needed to submit a second commencement notice for the amended plans, we would have done so. That one form would have saved us a huge financial burden.
When we tried to discuss the issue with the Council, we were met with a closed door and told simply, “It’s part of planning legislation.”
We’re now taking this issue to Parliament in the hope of changing the system and helping others in similar situations—people who should have qualified for CIL exemption, but lost it due to minor admin errors or a lack of clear guidance.
