I posted this thread to get a bit of advice, and feel I have now been criticised and made to feel like a terrible person for keeping my guinea pigs outside
Thank you all for your comments, I shall bring them in at night while it is still cold

Hi there and welcome to the forum

Please do not be put off. This is a friendly forum and everyone is here to help you.
I have 4 guinea pigs who live outdoors. My 2 newest additions who came to me as babies last year went to living outside straight away but Erin came at the end of March and Ena at the beginning of June. I new they would be OK as my elder 2 Eleanor and Eliza were there to help keep them warm.
My girls usually live outdoors all year round with the exception of this winter where I had no choice but to bring them in when the temperature dropped way below -10. The situation wasn't ideal at all as they had to live in a plastic storage box (a very large one) but they were happy enough and at least they were out of the cold.
I understand where you are coming from regarding your hubby as mine is allergic to the piggies and we have no room for them to live indoors.
For the last 3 winters (with the exception of this one), mine have been fine outdoors. However, you need more than a hutch hugger and plenty of hay. My girls had mountains of fresh hay in their sleeping area, plenty of cosy beds to cuddle up in, a thick fleece blanket to cover the hutch front at night, silver loft insulation around the hutch and snugglesafe heat pads
Snugglesafe Microwavable Heat Pad & Cover The heat pads are great as you just pop them in the microwave for 6 minutes ish and they stay warm for up to 8 hours. I also provided them with a large fleece so they could bury themselves in it if need be.
Here is my set up overnight during the colder weather
In my opinion, piggies can be perfectly happy outdoors but you must take steps to make sure they are warm enough and be prepared to bring them indoors if necessary.
When mine came indoors, they stayed in the back bedroom with no heating and the window slightly open so they didn't get to warm.
