Price per square metre
Knowing the average house price in SP8 is not much use. However, knowing average price per square metre can be quite useful. Price per sqm allows some comparison between properties of different size. We define price per square metre as the sold price divided by the internal area of a property:
£ per sqm = price ÷ internal area
For example in April 2026, 24, Hawthorn Avenue, Gillingham, SP8 4ST sold for £415,000. Given the internal area of 133 square metres recorded on the EPC, the price per sqm is £415,000 ÷ 133 sqm = £3,120.
England & Wales have been officially metric since 1965. However house price per square foot is prefered by some estate agents and those of sufficiently advanced age ;-). You can change your prefered units from square meters to square feet for all the graphs and charts on SP8 and elsewhere. Just visit the My Account page and look for the m2 to ft2 toggle switch. Alternatively just multiply everything by 10, move a decimal place to go from sqm to sqft and you'll be close enough as 1 sqm = 10.76391 sqft.
Distribution of £ per sqm for houses vs flats in SP8
The chart above is called a histogram, it helps you see the distribution of house price per sqm in SP8 To make this chart we put all the sales data into a series of £ per sqm 'buckets' (e.g. £3,142 to £3,308, £3,308 to £3,474, £3,474 to £3,640 etc...) we then count the number of sales with within in each bucket and plot the results. The histogram is based on 618 sales that took place in SP8, in the last 24 months.
Generate a custom histogram like the one above but based on your own criteria.
You can see the spread of prices above. This is because although internal area is a key factor in determining valuation, it is not the only factor. Many factors other than size affect desirability; these factors could be condition, aspect, garden size, negotiating power of the vendor etc.
The spread of prices will give you a feel of the typical range to expect in SP8, Gillingham. Notably, only 25% of properties that sold recently were valued at more than £3,770 sqm. For anything to be valued more than this means it has to be more desireable than the clear majority of SP8 homes.

The chart above shows changes in 'SP8' property prices over the last 20 years. The index is calculated from the average price paid per sqm for property in SP8 and is set to 100 in 2004. The chart compares trends for SP8, Gillingham against those of the broader postcode area 'SP'. What is more interesting is to look at the difference between flats and houses, even those in the same area follow a very different trend, to get a robust enough sample size to see this we need to zoom out and look at house price trends for the entire Dorset local authority.
The dashed lines show nominal house price changes, the solid lines show the same data adjusted for inflation. Economists call this the 'real' price change. You have to take inflation into account when comparing prices over time. It's calculated using the formula:
Real Rate of Return = (1 + Nominal Rate) ÷ (1 + Inflation Rate) – 1In this formula, the nominal rate is the rate of change before any adjustments, and the inflation rate is taken from the Consumer Price Index. The real rate of return is a more accurate measure of change in value, because £1 today does not have the same buying power as £1 in the past. For example, if a savings account pays an interest rate of 3% per year and the inflation rate is 5% per year, the real rate of return is -2%. This means that the investment's value is shrinking by 2% each year.

This table complements the house price index chart above, presenting the data in a more detailed format. It breaks down the information into 20-year, 10-year, 5-year, and 1-year periods, further categorized by property type. For each period, we display both a per annum rate of change and a total rate of change.
The total rate of change represents the overall change over the entire period. The formula for total return is:
Total return = (Index at end of period ÷ Index at start of period) - 1
The per annum rate of change is the annualized rate of change over the period. This is equivalent to the annual bank savings rate you would need to achieve the same total return over the given period. This annualized return is also known as the Compound Annual Growth Rate (CAGR). The formula for CAGR is:
CAGR = (1 + Total return) ^ (1 ÷ Number of years) - 1
Some specific examples:
- Over the past 20 years, SP area have seen a -0.5% annual change when adjusted for inflation. This translates to a total change of -9.4% in real terms.
- Over the past 5 years, SP8 district have seen a -2.7% annual change when adjusted for inflation. This translates to a total change of -12.9% in real terms.
