Withdrawn applications are counted in "decided" but never in a success rate — a withdrawal is usually a redesign, not a refusal. Categories are matched from the application's own wording, so a description mentioning two kinds of work lands in the first that fits.

While you are here

How people behave How long do people keep a home here? Half of all repeat sales are 2.7–7.8 years apart, with a median of 4.7 years. That is how often a given address comes back to the market. See what this is built from Asking prices Are sellers in Jersey asking more than the market has moved? On the 484 homes for sale that also appear in the sold register, the median asks 2.7% more than the index says its own last sale is now worth. 192 are above the index, 178 below. What would make this wrong: The index cannot see what has been done to a house between sales. A property extended since it last sold should ask more than the index says, and plenty have been. See what this is built from Planning What is hardest to get permission for in Jersey? Applications for new dwelling are granted 77% of the time, over 68 decisions; signs and shopfronts 95% over 75. Both are high — refusal is rarer here than people assume. See what this is built from
