depends on your budget if you can afford it get the serious illness cover,although with your husband self employed i would recommend permanent health insurance,so you'll have an income if anything happens to him,AND I WOULD NOT BUY ANY OF THIS FROM RHE BANK.
home insurance seems a lot but maybe your living in the city.
1% is average for solicitors but nagoatiate try fix a price as aposed to a percentage,dont forget theres 13.5% vat to be added to his bill plus expenses.
always get a house surveyed,very few houses show problems but if you get the one that does it will be money well spent,its peace of mind too.
