The annual survey, carried out by recruitment consultancy The Works Search and Selection, polled more than 700 PR professionals.
It found that 68 per cent of those surveyed had received a pay rise in the past 12 months, up from 41 per cent in 2013.
Sarah Leembruggen, managing partner of The Works Search and Selection, said: "We have come through a tough few years and the market is clearly growing stronger. We have seen increased confidence in the air as companies are keen to hire more talent. In spite of the high demand for exceptional people across the communications industry, this staggering 27-point uplift in salary increases still took us by surprise."
According to the survey results, a senior account manager is now paid an average of £35,000, up from £30,000 the year before, while senior account executives have seen their pay rise to an average of £28,000, up from £24,000 the previous year.
The survey revealed that senior account executives are likely to be promoted after just one year in their roles while account managers get promoted after an average of two years.
The upward pay trend was also reflected among agencies where consumer PR directors now enjoy an average salary of £95,000, up from £70,000 in 2013.
More than 50 per cent of respondents told the survey they received a bonus in the past year, an eight per cent increase on 2013.
Of those receiving a bonus, the largest was 18 per cent, which was paid to one global head of comms, while a senior account executive reported receiving a 10 per cent bonus.
The average bonus for in-house consumer PR was nine per cent while, for consumer PR agencies, the average bonus was 4.5 per cent.
Three-quarters of those surveyed said they were satisfied with their pay increases but respondents placed ownership of a role and a pleasant working environment above salary increases when asked for their priorities.
