"not on benefits because both actually earn a decent income working for themselves." Then they can bloody well rent somewhere! They need to go! 1 months notice - they're taking the piss!
Tbh you should have set ground rules before they even moved in.
I agree with pp saying its a power move - he's marking HIS territory - get your arse out the bedroom and tell him to have the decency to put a t-shirt on and not inflict his half naked body on others.
PLEASE say they're at least paying some rent?!
"she is a real giver." No she's not!
If rents are as high as you claim then they've been renting off you below market rate. TAKING.
Barely giving childcare TAKING (designed to make you feel beholden)
Making no effort to save for their own place TAKING
You say he's lazy I'll bet that extends to their business too so not maximising profit TAKING
making you feel uncomfortable in your own home TAKING.
"When she finally jacks work in they will I imagine be eligible for some kind of social housing" don't bet on it and certainly not if she's living with you, there's others in far more need and nowhere near enough housing. 5 years just makes them eligible to APPLY doesn't mean they'll get somewhere. Where are you? Sounds like London where in most parts there's already huge pressure on social housing. If that's what you're basing the "18 months" on you're going to be disappointed!!!
I'm in rural Scotland took me nearly 10 years to get social housing, dd and I both disabled, I'm also seriously mentally ill and not working so on benefits. This is not unusual. I have friends & family in various parts of the U.K. Inc London And it's much the same in most places

Most people would consider 18 months bloody fast!!
"They will be second from the bottom of the list, with only single men below them" yep!
Being retired is meaningless! The kind of thing that gets you "points" is dependent children, serious illness/disability, homelessness, serious overcrowding, victim of domestic abuse - and even people with these issues are struggling!

Trevor's unlikely to inherit much from his mum as her capital in her house could well go to providing her elderly care - why haven't they moved in with her? Ah they tried that already - I'd take their tale of her being the bad guy with a BIG pinch of salt!
"Prepare to be stared at blankly by your mum and Trev as you realise that staying with you is The Plan." Yep! Talk is cheap - actions speak louder.
If they're on a decent income they can bloody well save up and be out within 6 months max! They don't have to live in your borough if it's too expensive, I'm sure a neighbouring one will be cheaper and still within commuting range (if necessary - what is the business?)
They sound like freeloading, immature twats!
