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.
