Holidaymakers searching for a summer break have a tough challenge this year. Foreign travel restrictions due to Covid have thrown plans into disarray and UK accommodation is filling up quickly. But for those looking for a cheap getaway as Covid restrictions are lifted from tomorrow, a house swap might be just the answer. Such an arrangement allows you to stay at someone else's home at no cost while over the same time period they stay at yours. The concept is built on trust: you look after their home as if it were your own, knowing they are doing the same for yours.
