Sam said she wanted a "fresh start" with boyfriend Paul Knightley and their baby son, also named Paul, and had always liked the idea of living in Surrey.
But her mum Sue and sister Billie didn't seem too keen…
Sam was clearly not looking forward to telling them and waited until their girls' holiday in Majorca to break the news she'd been contacting estate agents in Surrey and hoping to uproot from Brentwood.
She noted to the camera: "It got frosty quite quick…"
Sue asked what made Sam want to leave Essex when she'd never mentioned it before, while Billie just seemed stunned: "I was a bit shocked because I thought, why would you want to live in Surrey with all of your family living in Brentwood or Essex. It was a bit, oh, you're trying to get away from us."
Billie told Sam: "I think you would feel isolated moving somewhere with no friends or family. I know Surrey isn't that far but it's quite far. It's not like I can just pop round and see baby Paul or you pop round and see Nelly. You haven't got any friends there or family there."
Sam, however, argued that friends and family were welcome to visit at any time and, of course, she would be still visit Essex and her family. "I have started my own family and I think it should be our choice where live and move to."
Her mum advised Sam to look closer to Essex before settling on Surrey but Sam pointed out she got more for her money looking in Surrey.
Sue admitted: "[Sam] is my baby and I just think I would miss her so much… moving somewhere that far away will be a massive change in all of our lives."
Billie, meanwhile, didn't seem to think the move would ever happen as she couldn't imagine Sam's boyfriend wanting to move away from his mum Gaynor.
Gaynor, however, said earlier in the episode: "They're talking about moving. Wherever they go, I'll go. Whether it means travelling or living. It doesn't matter, does it? I'm going to get closer."
