The survey, the first of pay and conditions carried out by Planning since 2011, found that only 49 per cent of local authority planners had an increase in their pay packet in the past 12 months, whereas 68 per cent of private sector planners enjoyed a pay rise.
Overall, 43 per cent of planners reported that they had their salary frozen in their most recent pay review, a drop from the 2011 figure, which was 64 per cent.
Previous surveys in 2007 and 2011 had recorded a median pay bracket of £25-£30,000, but this year's survey found that the sector's median pay category has moved up to £30-£35,000, with the number of respondents earning above £50,000 rising from 11 per cent in 2011 to 20 per cent this year.
The survey also found a significant gender gap in pay. According to the survey, the median pay for female planners is £30-£35,000, compared to £35-£40,000 for men.
The survey found three times as many men as women earning more than £100,000. According to the findings, only nine per cent of male planners earn under £25,000. For women, the figure is 17 per cent.
The survey also found evidence that hours worked by planners are on the rise, with the proportion working a 41 to 45-hour week up from 21 per cent in 2011 to 25 per cent in 2014.
