This stands higher than returns on standard residential property, which were 11.3% annually to October.
Ashish Misra, head of investment policy at Lloyds Bank Private Banking, said: "In the year to October, UK Commercial Property has been the best performing asset class.
“Investment returns on UK Commercial Property have been boosted as investor confidence has improved on the back of a positive economic outlook.
“Recovery in both the occupier and investments markets has been in full swing for much of the past two years raising demand, and with supply slow to respond, driving up rental growth and capital values.
“Whilst demand in London has driven returns for much of the period, recovery in the regions appears to be coming through more strongly now as well."
