MIL not sleeping over our house being too cold

We have a 5mo baby. We've just moved into our property which has an EPC C and insulated/double glazing, but since the weather's turned cold we've found our bedroom is far too cold, unsure why and we want to get a specialist in. We are a bit sparse with heating but we put it on morning and evening to heat house up to 16c, we top up in the day if its especially cold and use heaters/fireplace in certain rooms we use more so they're warmer than the 16c (including said bedroom but this was not effective). The rest of the house is fine except this one room. Me and baby are now sleeping in spare room which is much warmer. Baby is in recommended vest sleepsuit and 2.5-3.5 tog sleeping bag for the weather.

MIL is convinced the issue is we don't put the heating on enough and having arguments with my husband about it. She's said its not good enough that we're using our dyson for heating or that me and baby have switched room and we need to have the heating on more, and she thinks 16c is too cold. She has told me and my husband separately that she is so worried about our house she's not sleeping, citing worries for my husband's asthma and our child's health. The latter has upset me because I'm trying to follow the recommended advice for temperature and I wouldn't risk my child's welfare. Husband says I'm being over sensitive, and I know she probably doesn't mean to imply it, but I do think she should be thinking through what she says.

Husband is a tightarse and I frequently ignore his moaning and switch heating on anyway - however we both feel that the issue with the bedroom is not the heating, and that we think 16c is a reasonable temperature that will keep us healthy and should keep house in good condition. I don't know if I get especially warm but I woke up last night feeling too hot and room temperature was 17c. My husband similarly is ok with cooler temperatures.

My view is its our house and our baby and MIL has said her piece so now needs to reign it in. AIBU? I know she's grandmother and I can't stop her worrying but we're already navigating a new house and new baby and could do without her rattling me. I had a conversation with her earlier which was pleasant and constructive enough and I'm hoping will nip some of this in the bud, but I don't know whether to be tougher if there's a next time.

I resent putting the heating on and always try and refrain until November but I've been freezing since the beginning of October. When I'm home during the day and in the evenings I keep it at 18/19 and quick blast if I'm cold but at night I get hot so put it on 16. My house is well insulated and all my rooms are over other rooms.

Is your bedroom over a garage? I used to have one of those and I used to freeze at nights unless the heating was on at least 19. Why don't you try what MIL suggests, I'd find it annoying if she kept going on but she sounds right this time (which is even more annoying) 🤣.

Missey85 · 08/11/2025 07:35

I'm with your MIL that's freezing 🥶 I wouldn't want to stay over either

16 degrees?
Are you serious?
Mine is on at 24 most of the time, and boosted to 30 occasionally for short bursts.

You are joking? Wtf! What the hell is your energy bill like? 🤣🤣

24 is hot and 30 is ridiculous! I agree 16 is too cold, although that's fine for a bedroom while you're sleeping.

Scottishskifun · 08/11/2025 07:31

Have you got a hive system? If you can afford it then I suggest doing so and installing the hive radiator valves.
That way you can control the heating per room and time of day and it saves money long run.

I prefer a cooler house, our bedrooms are set to 17.5 overnight. You can get a gro egg which will tell you easily if temperature is right.

lessglittermoremud · 08/11/2025 07:28

Our heating is set to kick in when the house temp drops below 18 degrees. When our children were small we had a gro egg temperature light that we would go by and keep their room a little warmer but never over 20 degrees.
People are used to different temperatures, your MIL is being a little hysterical to be so concerned at your house being at least 16 degrees and you are being over sensitive.
My Mum’s house is too cold for me, around 14-16 degrees but she likes it and as it’s her house and she has to live in it I don’t nag at her about it, just say to her when it’s starting to feel a little damp so she runs the dehumidifier.

Velvian · 08/11/2025 07:26

16 degrees is a false economy; you will get damp and mould at that temperature. We started to get some when we reduced our thermostat to 18. We are set to 19 now and no problems.

Depending on your heating system, it may also be more economical to have the heating on constantly at a set temp than heating a cold house.

InMyOpenOnion · 08/11/2025 07:25

It seems like a lot of fannying about with measuring temperatures, heating experts and fan heaters whilst ignoring the massive elephant in the room. If your house feels cold or damp, turn the bloody heating up.

ItsAWonderfulLifeforMe · 08/11/2025 07:21

I think when posters mention a tight husband that controls the heating and refuses to turn it on (even though obviously it’s a joint house and you are all living there) this instantly screams control, always makes me feel sad for the OP to live with a man like that, how miserable

Chess101 · 08/11/2025 07:21

youalright · 08/11/2025 00:03

What are you doing pissing about with all these heaters and fires and getting workmen round to see why your house is cold put the bloody heating on and at a normal temperature like 20. It sound miserable thats not a home.

This. You’re freezing your poor baby living like that. Your mil is absolutely right!

FrangipaniBlue · 08/11/2025 07:19

Going against the grain……our thermostat never gets turned above 15 and in fact our heating hasn’t even been on for the last 5 days because the house is sat at around 16/17 degrees.

We don’t have damp and none us have health conditions because of it. DS is 17, perfectly happy and healthy.

Conversely - SIL/BIL are heating at 23 degrees people…. both of them and their 2 DC are CONSTANTLY poorly with colds and viruses; DN has respiratory issues that the Dr can’t really get to the root cause of and has done since they were a baby.

MrsDoubtfire1 · 08/11/2025 07:17

Should be between 18 and 21. Be careful having a new baby with those temperatures. Your MIL is only speaking with the best of intentions for her grandchild. Of course, you are entitled to say she is interfering but, from what I can read, it is from a place of justified concern. Your life, your baby, your choices but don't complain if baby develops any conditions because of the cold.

Lazygardener · 08/11/2025 07:15

16 degrees is very cold. If this is all you can afford, YANBU, but if it’s a choice then I don’t blame your MIL for wanting a more normal temperature.

Whoevenarethey · 08/11/2025 07:15

Sorry to jump on the bandwagon but agree your house is too cold, especially with a young baby and the issues with damp. We have dehumidifiers in the bathrooms to help with this and at this time of year need to have the thermostat at 18 minimum. If we are home all day and when it becomes colder in winter then we turn it up during the day.

I know you don't really get health visitors come so much anymore but my first was a winter baby and even though he was wrapped up, the HV came into our house and said it was too cold for a baby and he needed more layers (I like you was initially concerned about overheating so had gone the other way). I would listen to MIL on this.

HessianSack · 08/11/2025 07:06

I don’t think 16 is too cold, I like a cool room to sleep in and generally I think people have their houses way too hot these days. I don’t know where you live but we’ve not really had any cold weather yet, actually we’ve been commenting how mild it is. So you may need a rethink when the temp drops.

As an aside, how do so many posters know the exact temp of their house? I’m pretty sure heating thermostats aren’t that accurate. Do you have thermometers in each room?!

Read the op....
They heat up to 16 max for a couple of hours a day.

They have a new born.

And yes i have hive and know temps in each room especially my 3 and 1 yr olds

Theextraordinaryisintheordinary · 08/11/2025 07:12

I have mine on 20 just for the dogs. I would not want to stay either at 16 degrees. Sorry.

SalmonOnFinnCrisp · 08/11/2025 07:09

Yabvu and either stupid or foolish.

She is (correctly) trying to tell you HOW concerned she is for her GC

what is wrong with you?
The house is 16 MAX so presumably 12-16 most of the day. That is just too cold for a baby that small.
A drop to 14 or so in the middle of the night for a few hours is fine but what you describe is not okay

If money is such a problem cut back elsewhere.

If i was in the situation and had no additional money i would actively be raising money to heat the house.

Heat the house to 18 degrees minimum and stop being tight arses.

Happyjoe · 08/11/2025 07:09

Agree, too cold. Too cold for the elderly and too cold for babies afaik. The recommended temp is 18-21 oC.
If you hate a warm house, get those plug in oil filled radiators so guests and children can have warm rooms. 16 is uncomfortable for most.

RealOliveTraybake · 08/11/2025 07:07

YANBU. Our house is normally at 14 for sleeping and during the day, heated to 16-18 if we're not doing much and in the evening. 20 is psychotically warm.

GehenSieweiter · 08/11/2025 07:05

16 is fairly cool, you'd notice a huge difference in comfort if you upped it to 18, still a conservative warm for some but much more reasonable. Ignore those who are suggesting 24 or 30, that would be fair too stuffy and ridiculously expensive.

TheCurious0range · 08/11/2025 07:02

Why is your house that cold? I walked from my office to boots yesterday in a cardigan it's only 14 degrees outside. I live in an old Edwardian semi windows are double glazed but old. High ceilings , original wood floors and too knocked through for for the age of the building, our heating clicked off around 7:30 last night and it's currently 20.degrees downstairs which means it is a degree or two warmer upstairs (which is fully carpeted with smaller rooms than downstairs).
You need to check that thermostat is accurate. Also using heaters is probably costing you more than having the heating set to 18

ChipDaleRescueRangers · 08/11/2025 07:00

16 degrees is the HSE minimum temp for working (not including food production places). It is cold! Put the bloody heating on to 18 minimum.

Chanelo · 08/11/2025 07:00

I don’t feel the cold but 16c is objectively on the cold side and you’ve had to move rooms because of it. You probably have a cold external wall in the main bedroom and layer of insulation will help.

18-20c will be more comfortable for the daytime.

Put the heating on a timer.

cannynotsay · 08/11/2025 06:58

Im not one to agree often with the MIL but she’s so right, not surprised she’s worried! 15/16 is when I put the heating on, to avoid damp and cold. Girl get over yourself, your husband too and stop being a tight arse and put the damn heating on xx
