It’s after it was revealed the authority borrowed £1 billion between 2016 and 2018.
The money has been used to invest in a commercial portfolio of office buildings in and around the borough.
Spelthorne’s bosses say this portfolio has generated approximately £50 million return every year.
The cash is spent on front line services like ‘Meals on Wheels.’
There is also £38 million in reserves for, as the council puts it, a “rainy day.”
Bosses say it will not fall into the red as councils like Croydon and Woking have done, because of “prudent” forward planning.
