To expect my home to be somewhat insulated?

[OnNaturesCourse]

Rented property. £650pcm which is average for the area and size of property. We have a ongoing issue with the roof which the landlord has been promising to fix for 4 years, it leaks and causes the loft hatch to bang. We have original double glazed windows that have broken seals so bad that there is water build up between the panels. Damp/mould in all the upstairs rooms.

With the issues we struggle to maintain heat in the home and its costing us a fortune.

Our heating is on for 2 hours in the morning/until it reaches 18°, if we are staying home ill boost this to stay on at 16° but if I don't it easily drops to 14° within a hour or so. In the evening the heating is on for 5 hours to 20°. From 11pm to 7am the next day our home drops to 9°.

Landlord seems to think this is pretty normal for a mid terrace, 6 room house.

What sort of heat does your home lose?
(landlord seems to think the roof etc is not urgent as the house is safe and habitable etc)

Try searching by street .
It's a £2,000 fine if you landlord dues not have a valid EPC

I'm in Scotland so different site, no option to search that way unfortunately

@OnNaturesCourse
Apologies I missed the fact you are located in Scotland I sent you the Link for homes in England .
Unless you have rented your home prior to 2008 you landlord must provide an EPC to comply with the law.

If you moved in prior to 2008 your landlord does not need to provide an Epc in Scotland
.
Different law in England , all rental properties must have an Epc.

I have requested the info from landlord as its not online anywhere.

I moved in post 2018 so assume it should have one.
