Job search website Adzuna said annual advertised salaries averaged 36,946 pounds ($46,038.41) last month, down 0.4% from September and taking the decline since April to 1.9%.
"Falling advertised salaries may not appear to be good news for jobseekers but it does signal that the menace of inflation is finally in retreat," Andrew Hunter, co-founder of Adzuna said.
However, online job ads climbed 0.35% to 1.03 million adverts, the biggest month-on-month jump since June, helped by pre-Christmas hiring in sectors such as retail and warehousing.
But it is closely watching for signs of inflation pressure in the jobs market.
An official measure of vacancies, published earlier this month, showed vacancies hit a two-year low of 957,000 in the three months to October and near record wage growth cooled slightly from in the quarter to September.
