The question I get asked the most is what the cost of living is like here in the UK, compared to Denmark.
Before I went here, I honestly did not put much thought into it, my logic being that I had a full time job waiting for me, and that if the locals can live based on what they get paid, then so can I.
Thinking about it a bit further - an employment here has to be able to pay for mortgages, a car, a house, kids and more for regular people to be able to live a life. Being single with no debt, kids or anything else to soak money out of my bank account, it should be super easy.
It is.
I don't make a lot of money, but I live cheap. Not that I have to, I just do, with plenty of spare change for whatever I fancy.
Accommodation...
is easy to find, there are plenty of sites that offer places to stay. My recommendation will be to find somewhere with a Live In Landlord/lady. That way you will also be able to make some easy connections and have a person to answer the most simple questions about living in your area. I know things are really expensive in London - so stay away from there and you can easily find something (for 1 person) at around £350-450/month. As a couple, £600-700 is probably the cheapest you will find.
Food...
is cheaper here. Partially due to lower VAT but that does not account for all the differences. Coming from Netto DK, looking at prices in Netto UK, it is easy to see that prices are lower when I have such a direct way to compare everything. Be it meat, Fruit&Veg, frozen or bread, it's all cheaper.
Phone/Internet
Electronics in general are priced the same here, but connecting to the world around you is expensive. It is not as bad as New Zealand was, but sort of in the middle. In Denmark, you can easily get virtually unlimited data at around £8/month. There is no such thing here. Also, most companies do not accept foreign cards for "security" reasons.
Doctors
Are free. Well, there will usually be a walk-in centre near you which is free. Any medicine you may be prescribed is a flat rate of £8, and can be picked up in any pharmacy (they may charge for card usage). Be careful with some companies however, they may charge you a lot for something you could get for free when it comes to non-prescription medicine.
I'll add more to this post if I get any questions that aren't answered above.
