The black-tie event by Portsmouth Property Association was held in honour of a charity run by a former England rugby union star.
Donations for the Dallaglio RugbyWorks, founded by World Cup winner Lawrence Dallaglio, will help disadvantaged local teenagers turn their lives around through fresh opportunity.
Dozens of members and guests attended the city event, held at The Royal Maritime Club, which has Prince Charles as patron.
Tom Holloway, PPA chairman, said: ‘More than £6,000 has been raised, with further donations coming in.
‘ Once again PPA members have touched down with their generosity and I’d like to thank them for their kindness and continued support for the PPA, which was founded 99 years ago and has stood the test of time.’
Guest speaker was Hazel Irvine, a sports broadcaster for ITV and BBC for 25 years.
Her speech was followed by a charity auction hosted by Clive Emson, a renowned auctioneer who is chairman of one of the largest property auction firms in the country, Clive Emson.
The record auction bid on the night was £350 for horse racing at Goodwood’s May Festival. A prize raffle also saw significant amounts of money raised.
PPA’s 150 members include estate agents, auctioneers, lettings and property management agents, commercial property agents, chartered surveyors, developers, accountants, solicitors and bankers. Its 100th Centenary Dinner will take place on March 13, 2020 at Portsmouth Guildhall.
