To ask them to put the heating on,?

Legally, the minimum temperature in a workplace is 16 degrees (only 13 if you are doing something strenuous). Temperature in the workplace: Is it too cold or hot to work? - HSE

So I would say you definitely need to raise this (and offer to pay if that's what makes it OK for them to put the heating on).

I have a heater in the office I bought for the baby 23 years ago. Suggest you get one choose a room and keep the door shut. We don't have the heating on all day but the log burner is lit at lunchtime because it's so cold at the moment.

I'd ask but expect the partner to moan about it!

Sounds like my Mum, she won't put the light on when it starts to get dark either. My DH turned the light on when we were at Mum's over Christmas, I told him she'd comment about it when she came back into the room, and sure enough she did. I bet she was itching to turn it off as soon as we left, old habits die hard!

Or ask for a hot water bottle and blanket

Absolutely I can not be cold- I would tell them how cold I was (I suffer from Raynards and chilblaines) and if the wouldn't I would politely leave and not return

If you don't feel cold that's fine. But you said it was cold.

No not really. I was not brought up to wear shorts and tee shirts in the middle of winter like so many people now so it wouldn't occur to me to need the heating on.

I'm also pretty active so I'm not sitting around in front of the TV getting cold.

I would ask.

If you're working from their home while they're out, I'd say "I know you don't normally like the heating on when you're not home, but would it be OK if I put it on while I'm working please - I was freezing earlier. I'll give you some money to cover it so you won't be out of pocket."

I would find that a miserable way to live. And if I really was concerned about paying for the fuel I would cut back in other places first.

Currently 13C in my house. Oodies are a great invention.

The heating will come on at 5pm and no - we do not have any damp. It's just cold

I simply wouldn't stay there to be honest

If it's less than 22, ie the actual recommended guidelines, I would ask for it to be turned up.

I do it everywhere, even did it in pizza hut yesterday.

No shame here.

my house and business are both 24, so I practice what I preach.

My brothers and I have tried - it is almost impossible.

''But we used to live in a farmhouse where one had to break the ice in the water in the morning for a wash''

Things definitely were tough for people in the War- they are known as the ''silent generation'', but a lot of them are actually fairly well off now, by dint of good pensions and buying property when it was cheap in relation to wages.

THIS ☝️

It's the rationing thing.

Mum won't throw anything out of her fridge, either.

It's crazy.

Rationing at such a crucial stage of their childhoods has left an indelible mark on their psyche.

''Make do and mend'' - don't waste food...my neighbour was the same {War generation} - she actually got upset as someone was giving her cooking apples off their tree, and Doreen as a widow of 90 couldn't possibly use up great bags of cooking apples.

I took them away and put them on. a compost heap as she was so distressed about waste.

Do people even use cooking apples these days?!

He's a parsimonious old fool then.

Older people are at far greater risk of health issues when their houses become cold- and 13 degrees C is bloody freezing.

Mum went through a phase of this- 13 degrees, sat indoors with a wooly hat, coat, gloves - it's a kind of wilful stubbornness, I think? with that generation-

One cannot be comfy in heavy outdoor clothes indoors.

I can't BEAR a cold house...18/19 degs C is how I heat mine, but seeing one's breath plume in a house is bad.

I was bought a heated throw by Mum {she has one too} and they are fabulous!
Dog adores it, too, and lies on it.

I work for Age Uk and recommended temperatures for the house are 18 degrees minimum.

Could you go 'is there a window open somewhere? Its been freezing all day, shall we pop the heating on?' And see what the reaction is and go from there?

Given their age, a room temperature that low is a health risk - increased risk of stroke etc. So he may not listen, but a reasonable room temperature is definitely not a waste:

I visit my aunty who won't put her heating on, the thermostat is at about 11°.

As soon as I walk in I say its bloody freezing in here, turn the heating up. She says she's quite warm (whilst shivering under a blanket). I tell her that's a complete lie and she's ruining her home and health....she still doesn't turn it up but I've tried.
She's got loads of money, just received over 100k inheritance. I just can't comprehend these people!

I feel like you should be able to tell your mum, yes your a guest but it's your mum too.

I would expect my adult children just to turn it up!
If I was in someone else's house I would do what someone else suggested and offer to pay for extra heating, explaining the it's too cold for you to work effectively.

It's near impossible to change people's attitudes to money/when to put heating on. Has caused friction with a loved one re varying attitudes.
As it's your mum's house, I think u should feel comfortable in asking.
