Hi Imorr:
First thing (and I'm sure some teachers out there can confirm this) - but KS1 SATs scores are not publically reported (as in on League Tables) - so it is just a private result between you and the school.
Second - Y2 tend to sit SATs in May (I think that's still the case - but perhaps teachers can confirm).
Difficult - as not prepping your daughter means she'll not do so well, possibly below expectations nationally which will make the school look bad (which they deserve).
However leaving things to be ultimately harms your DD's life chances.

So the issue here seems to be that you're unhappy with how your DD is doing.
The writing backwards thing is typical in KS1. I had two DDs who came into their primary school able to write 1 to 10 correctly, and then gradually started flipping numbers. I was horrified by it - but suspect that working on tables and seeing teachers/ TA materials upside down may have this effect.
Solution: Try and catch it. Have them practice. Make up little mnemonics - and use drawing hints. So with 5 and 3 - draw a little monster on the right. Under the horizontal of the five draw the face - five suffers from curiousity so turns to the monster on the right.
Draw a face under the upper curve of the 3. Poor Shy Three can't bear to see - so turns away from the monster to the left.
with 6 and 9 - I try to have my DDs imaging they're small plant and draw a sunshine on the top left of the page. With the 9 it's the height of summer - the flower in the 9 (the circle) turns to the sun. With the 6 it's late winter (say February) and dark and cold. The little shoot, first creeping out in the deep dark winter can't find the sun, so goes the wrong way. Mad - but it seemed to work.
With two, three & seven - draw a little ghost on the right and faces under the curve of the two & 3, and draw the face under the horizontal of the 7. The 2 runs from the boo, as does the 3 & 7 - so you now know which direction.
Fortunately 1, 8 and 10 are well behaved until you DD gets into topping and tailing the 1. I then add it to the 9 scenario - the first pettle of the flower heads toward the sun. (Yes, DD2 decided to catch me out on this)

If like me you're unhappy with how things are progressing.
Join a library (or on-line book club) and start practicing reading yourself. Read book review sections or look at websites about recommended books for certain reading ages. Examples include www.booktrust.org.uk/books-and-reading/children/best-book-guide/ or the guardian's advice on building a children's library: www.guardian.co.uk/books/series/building-a-children-s-library or try the family education lists: school.familyeducation.com/literature/reading/34576.html
Take every opportunity to write - thank you cards, invitations, captions to pictures, scrap books, etc... Encourage your DD to practice writing styles - so fancy, swirly, big, huge, small. Have the write with a stick in the sand on the beach or in the dirt in the garden.
Join an on-line maths learning site - there's a number. I've posted about Mathsfactor themathsfactor.com/ - but there are others. It really depends on whether you're looking for replacement teaching (which was our situation - teaching at school & homework just not that good) or whether you're after a bit of practice.
KS1 bitesize - www.bbc.co.uk/bitesize/ks1/ - offers lots of practice/ fun play in all the categories examined in SATs - so is a useful resource and frankly once you've got your DD set up on a game, you can get on with cooking, doing the laundry, etc... and they're fairly content.
Finally - If you feel that you'd like more info/ learning materials than check out BBC Learning (still in BETA).
www.bbc.co.uk/learning/
select schools on the options on the right
on the next screen, select teachers on the options on the right
on the next screen, select the KS1 tab
and then select the subject you are interested in. This will link you to all sorts of resources - lesson plans, worksheets, videos, games, etc... - but it is a great way of understanding what's possible and I've downloaded a lot of extra worksheets, which I use selectively - inset days, doctors/ dentists waiting rooms are great for worksheets & when my DDs are really into something and want to find out more.

Are all schools like this?
Short answer is probably No - but many schools seem to go through arcs of getting really lax and them whipping themselves (and the students) into shape pre-OFSTED. If OFSTED is due to inspect in the next few years I can assure you things will improve remarkably.
As a parent - what you should be looking into is what will teachers next year & beyond be like. So if the school ground consensus is KS1 is lousy, but wait until they get Mr XXXX, he's fantastic and gets great things from them - then it may be worth hanging in there.
Is this just the state of education in Britain now? Or should I be asking for/expecting more?
Kind of a major question. Interestingly I've been e-mailed by friends in the US who report that US papers are saying Britian will not come out of the next recession because their education system is only good for a small percentage of pupils who are privately educated.
Now obviously there's an agenda there in this report coverage - but I had an interesting conversation with a teacher friend where I slightly went unhenged about things at my DDs' school and she basically gently said that if I want a good education, it has to be private. The state sector only works if parents keep on top of what is going on and help with learning at home.
So my hobby has become researching what my DDs should be doing and trying to supplement limited homework with good learning materials/ ideas - to just get them through. I send in suggestions to the school and sometimes they take them up and sometimes they don't - but meanwhile we keep paddling away at Chez PastSellByDate.
Are my expectations too high? Probably - but then I feel that if the school will endlessly spout on about their high expectations/ standards, then they shouldn't endlessly disappoint. If they have high expectations/ standards than I should be impressed. I'm pretty clear that so far nothing has impressed. Possibly because in 4 1/3 years for DD1 and 2 1/3 years for DD2 no school work has come home letting me understanding what's going on in class, very little homework came home until Sept, when we entered the school year when OFSTED would be coming & quite often I've had to undue appalling grammar (give me them pencils Mummy, etc...) makes me cringe - that's definitely from school - and not just their classmates.
