There are plenty of arguments for lifting the public sector pay cap but eMoov has added to the mix by highlighting the affect on nurses, doctors, police and firefighters getting on the property ladder.

Research by the online agent, looking at the period since the introduction of the cap during 2012, has found the average UK house price, based on Land Registry data, has increased by more than £50,000, up 31.12%.

However, at the same time, a 1% cap on public sector wages means that they have grown by just 6.03%.

In 2012, the average house price was £167,854, but the average public sector salary was just £25,060.

With a mortgage lender typically lending 4.5 times this wage and a 10% deposit of £16,785, a public sector employee could only afford to buy a property at a value of £129,556 – a difference of 29.56% between that and the average house price, the research shows.

Since then the gap has continued to widen, increasing by 29.59% in 2013, 37.27% in 2014, 41.61% in 2015 and 49.45% in 2016. So far 2017 has seen the largest gap emerge at 55.46% with the average house price topping £220,094, yet the average public sector wage has continued to stagnate at £26,571.

As a result, a public sector employee today can only secure a mortgage for a property valued at £141,579 when including the 10% deposit of £22,009, according to the research.

It gets even worse by 2020, when the cap is due to run to.

Based on the last three years of both house price and public sector wage growth, the average house price could be in the region of £263,940, with the public sector wage reaching just £27,581. If this were the case, then public sector employees would only be able to secure a mortgage on a property to the value of £150,507 with a 10% deposit of £26,394, a gap of 75.37%.

Russell Quirk, chief executive of eMoov, said: “The plight of today’s aspirational homeowner is a well-documented one, but it isn’t just a matter of age, and the year you were born, the sector in which you choose to build a career can also have huge implications on your chances of getting on the ladder.

“It is very disappointing that those arguably the most deserving of a foot up on the ladder are the ones left well off the pace.

“If the cap were to remain in place until 2020, the difference between salary, the amount of mortgage available and the average house price will be cavernous for those in the public sector.”
