The first Grenfell Tower firefighter is already staying in one holiday cottage in Richmond.
“About four days after the fire happened I had been watching the news and kept going outside and everything looked so green and beautiful and clean,” said Ms Briggs.
“I wanted to help but we are so far away. I started to read some blogs by firefighters and the awful things they experienced.
“I thought maybe because we were so far away it was a good thing to come here, as you can come here and feel totally different in the fresh air amongst all the greenery.”
She got in touch with The Fire Fighters Charity, who will match up the breaks with individual firefighters, who are being psychologically assessed.
“The charity said it will take a while because they have to look at the individual needs of the firefighters and a psychologist has to assess them because a lot of them are really, really traumatised.
“When they were in the building they were having to make decisions such as whether to save an old person or children; they were literally taking life or death decisions.
“The Fire Fighters Charity will assess their needs and try and match them up with the most appropriate holiday, such as dog-friendly accommodation.”
The charity will offer breaks to firefighters as they take their leave throughout the rest of the year and liaise with other organisations to offer any remaining holidays to police or ambulance crews affected.
