This is a map and list of properties recently sold in the SG3 postcode district in the UK covering the areas of Knebworth, Woolmer Green, Datchworth, North Hertfordshire, based on the records of the Land Registry
The average price shown is the geometric mean which multiplies all sales prices together then takes the square root. This should reduce the impact of sales of very expensive houses.
No adjustments are made for seasonal variations, so average prices will not match the Land Registry's own figures
Sales in the final month are always lower than earlier months, due to that month's data not being complete.
