Price per square metre
Knowing the average house price in Caerphilly 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 September 2024, 3, Hillcrest Avenue, Caerphilly, CF44 6YH sold for £160,000. Given the internal area of 73 square metres recorded on the EPC, the price per sqm is £160,000 ÷ 73 sqm = £2,191.
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 ;-). It is a huge pain to code the automatic conversion for square meters to square feet for all the graphs and charts on Caerphilly and elsewhere. All the conditionals turn my tidy code for into spaghetti. I will get around to it at some point, but for now you can just divide everything by 10 in your head, move a decimal place and you'll be close enough. If you want to be more precise 1 sqm = 10.76391 sqft.
Distribution of £ per sqm for houses vs flats in Caerphilly

The chart above is called a histogram, it helps you see the distribution of house price per sqm in Caerphilly To make this chart we put all the sales data into a series of £ per sqm 'buckets' (e.g. £2,350 to £2,500, £2,500 to £2,650, £2,650 to £2,800 etc...) we then count the number of sales with within in each bucket and plot the results. The histogram is based on 1,343 sales that took place in Caerphilly in the last 12 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 Caerphilly. Notably, only 25% of properties that sold recently were valued at more than £2,750 sqm. For anything to be valued more than this means it has to be more desireable than the clear majority of Caerphilly homes.
Box plot of £ per sqm for Caerphilly
Tip: click on the chart to see the values.
The chart above is called a boxplot (or a box-and-whisker plot). Box plots, like histograms, are used to graphically represent the distribution of data, showing the central tendency, spread of the distribution. In the context of £ per square metre property price distributions, box plots represent the variation in property prices within a geographic area e.g. Caerphilly. The chart above shows a boxplot for 'Caerphilly' broken down by property type (Flats, Semi-detached, Detached and Terraced). Almost everywhere houses command higher prices per square metre than flats, and detached houses most of all.

The chart above shows changes in 'Caerphilly' property prices over the last 20 years. The index is calculated from the average price paid per sqm for property in Caerphilly and is set to 100 in 2004. The chart compares trends for Flats vs Houses in Caerphilly. You can see how different they are. Keep this in mind when you see any price index that doesn't provide this breakdown.
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, Houses have seen a 0.8% annual change when adjusted for inflation. This translates to a total change of 18.0% in real terms.
- Over the past 5 years, Houses have seen a 2.3% annual change when adjusted for inflation. This translates to a total change of 12.0% in real terms.
Transaction volumes
Property transaction volumes in the UK follow a cyclical pattern. In addition to seasonal trends that occur annually, transaction volumes fluctuate with changes in house prices. When prices are rising, transactions typically increase, whereas falling prices tend to result in fewer sales, with only motivated sellers (e.g., due to death or divorce) entering the market. Exceptions to this trend often occur when changes to Stamp Duty drive a temporary surge in transactions.
Number of properties sold in Caerphilly
The chart above shows the number of properties sold each month in Caerphilly as reported by Land Registry. Key events highlighted include the Northern Rock bank run at the start of the 2007/8 Financial Crisis, the introduction of additional Stamp Duty on second homes in April 2016, the COVID-19 lockdowns and subsequent Stamp Duty holiday, and the 2023 interest rate rises. It's important to note that Land Registry reporting is lagged, particularly affecting new build sales, so treat the last year of sales volume data with caution. Based on historical reporting lags, I've provided a crude forecast of sales volumes for Caerphilly, shown in yellow.
