Nadia Butt, UK and Ireland country manager at Spotahome, said: “Location is key for many London renters, but it’s often the first thing we compromise on to keep costs down.

“While this is inevitable in a market such as London, compromising on location doesn’t necessarily mean moving miles away from where we want to be.

“Our research shows you can cut your rental outgoings considerably in every borough of London, simply by moving from one part to the other.

“While you might not be exactly where you want to be, it means you can remain a short distance away and still have more money in your pocket after your rent is due.

“Particularly in the current circumstances, many tenants may be struggling financially and by being able to reduce what is likely to be their largest financial outgoing, this could make a real difference.

“With such a diverse rental market, finding your perfect London rental is all about research.

“The more time you spend on it, the more likely you are to find a suitable more affordable property.”
