The borough was ranked 14th in the UK, according to 26 different factors which prospective homebuyers may consider when looking for a house.
The criteria included urban environment – number of burglaries, traffic, emissions and population density; education – class size, results and per-pupil spending; and lifestyle – pubs, fitness centres and ultra-fast broadband.
In terms of housing, Halifax examined the ratio of prices to earnings. Other topics included earnings, employment, well-being, life expectancy and weather.
East Hertfordshire came top of the list, with Tonbridge & Malling the highest-ranked in Kent and the fifth best in the south east.
Russell Galley, Managing Director of Halifax said: “Everyone has different priorities when it comes to choosing a place to live, depending on time of life, and personal circumstances.
“Affordability will always be one of the most important factors, with getting a foot on the property ladder still difficult for some people.”
The news comes after a survey by property website Rightmove found that Tonbridge was the third happiest place to live in the whole of the South East and 22nd in the country.
