Price per square metre

Knowing the average house price in St Thomas 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

E.g. 33, Delhi Street, St Thomas, Swansea, sold for £123,000 on Jul-2024. Given the internal area of 80 square metres, the price per sqm is £1,537.

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 ;-) They may want to convert square meters on this page to square feet.

The chart below is called a histogram, it helps you see the distribution of this house price per sqm data. To make this chart we put the sales data into a series of £ per sqm 'buckets' (e.g. £1,900-£2,000, £2,000-£2,100, £2,100-£2,200 etc...) we then count the number of sales with within in each bucket and plot the results. The chart is based on 139 sales in St Thomas (SA1 8) that took place in the last two years.

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 St Thomas (SA1 8). Of the 139 transactions, half were sold for between £1,360 and £2,150 per square metre. The median, or 'middle', price per square metre in 'SA1 8' is £1,560. Notably, only 25% of properties that sold recently were valued at more than £2,150 sqm. For anything to be valued more than this means it has to be more desireable than the clear majority of homes.

Data from Land Registry comes in gradually over time. I update it every month but it takes about 5 months for the majority of sales for Swansea to be recorded. Disclaimer: I do not verify and cannot guarantee the accuracy of any data shown. Outliers exist in the data, typically these are where the EPC registry records the internal area incorrectly, sometimes although very rarely the Land Registry price paid data can be wrong.

Any information provided does not and cannot ever take in to account the particular financial situation, objectives or property needs of either you or anyone reading this information.
