Indeed - basically "thou shalt not tip off the council (or whoever) about the possibility of something not being right". That's in the policy we have for the extension on our house. As an ex-council house there's a covenant about not building anything without permission from the council "not to be unreasonably withheld". That permission is separate to planning permission and building regs.One interesting thing I came across when looking around this topic is that these 'indemnity insurances' are nearly always invalidated if the policyholder, or anyone associated with them, has ever made an enquiring of the LA regarding LABC approvals.
Given the number and size of extensions (or even complete new houses) that have gone up locally I'm not too worried about it - but the insurance is there to cover the legal fees should we find ourselves with any problems.
IANAL, but I think it would be an interesting question to ask as to whether planning permission constituted permission from the council in respect of the covenant. It's certainly permission, and it's from a part of the council.
You may have a known fact (e.g. non-notified work) - but there is still the unknown of whether the council will do anything, or if any action will go further than "apply retrospectively please".I suppose that makes sense since, if one has made such enquiries, one would then be seeking 'insurance' in relation to something which was a known fact! - i.e. if it is known that work was undertaken without permission (within a timeframe that could lead to an enforcement notice), once cannot insure against the 'possibility' of that being the case!
