What's fair here? (Co-habiting couple)

[PropertyProblems]

Sally earns £30k. She has savings and is planning on buying a BTL for her own security.

Harry earns £40k. He owns a house and pays £900 per month mortgage with £1k interest per year.
He has an 8 year old son (not Sally's) 50% of the time.

Sally is moving into Harry's house. They are planning on getting married soon.

The house bills are as follows:
Council tax: £150 per month
Gas/ electric £250 per month
Food: £300 per month
Car (shared): £200 per month

Sally is currently paying council tax, food, and car. Harry is paying mortgage and gas/ electric. Harry thinks that sally should start paying the electric bill.

Is this fair? If not, what is?

@PropertyProblems Ate you sure the £1000 per annum interest is correct?

It's for them to work out themselves I would say. Moving into a house solely owned by your partner is always a risk when you are not married. If they are already disagreeing about who pays for what the future doesn't look good.

I think this is fair yes, I don’t really understand rhe mumsnet concept that if you live in your partners house then you should live rent free and are entitled for them to provide the roof over your head and you should just contribute to thr bills.

Personally I think it should be fifty fifty snd sally is not entitled to rent free accommodation.
