New ONS Calculator Shows What You Need to Earn to Buy a Home in Kent

Families across Kent wondering whether they can afford to buy their first home now have a clearer picture, thanks to a new calculator from the Office for National Statistics. The interactive tool breaks down exactly how much you need to earn and save to purchase an entry-level property in your specific neighbourhood.

For many residents in areas like Medway or Thanet, the calculator provides a reality check on local housing costs. It uses lower quartile house prices – essentially the cheapest quarter of properties sold in each area – to estimate what first-time buyers actually face in the market.

How the Numbers Stack Up

The tool assumes typical first-time buyer conditions: a deposit of around 15% plus conveyancing and survey fees. This reflects what most people actually experience when buying their first home, rather than theoretical scenarios.

Across England, the median house price hit £290,000 in 2024 – that’s 7.7 times the median full-time earnings of £37,600. Wales fared better with homes at £201,000, or 5.9 times typical earnings of £34,300.

The contrast between different areas remains stark. Blaenau Gwent topped the affordability charts with house prices just 3.8 times local earnings, as Kensington and Chelsea sat at an eye-watering 27.1 times average income.

Signs of Improvement

There’s some welcome news buried in the data. Affordability improved in 91% of local authorities across England and Wales in 2024 compared to the previous year. Areas where house prices exceed 12 times local earnings – traditionally considered severely unaffordable – dropped from 76 locations in 2021 to just 34 in 2024.

This improvement stems from a combination of wage growth and cooling house price rises. But challenges remain, chiefly for renters facing increased costs while trying to save for deposits.

Local councils across Kent rely on this ONS data for their housing need assessments. The Standard Method uses affordability ratios to calculate how many new homes each area requires, directly influencing planning decisions and development targets.
