"The great British summer forecast couldn’t have come at a better time," said website co-founder Jackie Wiltshire.
"With the recession, the weak pound and now swine flu putting people off foreign holidays, the great British getaway will be bigger and better this year than ever before. And for home swappers, that great getaway will be absolutely free."
UKHolidaySwapShop.co.uk said it now had now more than 500 homes listed by swappers.
Among the bargain breaks are a two-bed cottage in Lyme Regis, Dorset and a three-bedroom holiday home minutes from the beach in Portrush, Northern Ireland.
There are also plush city apartments and sprawling country houses – something for any great British summer break.
But would-be swappers need to be quick if they want to take advantage of the current membership offer.
Up until the end of June you can list your home and have full contact privileges for a year for only £14.95. Members can contact and swap with as many other properties as they like, at no extra cost.
