In 2021, Tendring District Council issued a Certificate of Lawfulness confirming that a planning permission granted in 1998 for a replacement dwelling near St Osyth remained extant and capable of implementation.
The site had sat dormant for over two decades following demolition of the original house. I argued successfully that the demolition itself had constituted commencement of the development, keeping the permission alive despite the intervening years.
Certificate of Lawfulness for a Dwelling Tendring
I secured a Certificate of Lawfulness from Tendring District Council for a client who had inherited a plot of open land near St Osyth in Essex.
A house had once stood on the site, and planning permission had been granted in 1998 for its demolition and the construction of a replacement dwelling. The existing house was demolished in the early 2000s, but the new dwelling was never built.
The key question was whether the original planning permission was still live.
This mattered enormously, because Tendring's planning policies had changed significantly since 1998. A fresh planning application for a dwelling at this rural location would not have been supported — the principle of development could not have been established under current policies.
If the original permission had lapsed, the site had little or no development value.
The legal answer turned on when, if ever, the development had commenced. Under the Town and Country Planning Act 1990, development includes 'building operations', which expressly includes the demolition of buildings.
The original 1998 permission had approved the demolition of the existing house as part of the scheme. Since that demolition had taken place, I argued that development had been lawfully commenced in accordance with the permission, which therefore remained extant.
Tendring District Council accepted this argument and issued the Certificate of Lawfulness, confirming my client could proceed to build out the replacement dwelling under the original 1998 consent.

If you have an old planning permission where works have commenced but the development was never completed, a Certificate of Lawfulness may be the right way to establish whether it can still be implemented. Contact me to discuss your situation.
