I don't see that as bad news. Why people would want to pay £120 a year for a permit (and believe me that is what other councils charge) together with the inconvenience of having guests over and having to provide them with temporary passes I struggle to fathom. Balanced against the very slight inconvenience of parking 100m down the road there is a clear winner here. It's not like motoring is a steal as it is.
It's almost like people want to pay more to Lewisham council.
If you want to park outside your house, buy a house with a drive way.
