Advice please! Considering swapping from love out nanny to live in au pair

[JugglingChaotically]

Bit of a scary step but full time nanny is silly with 3 at full time school and financial pressures mean we need to make the move so-
3DDs. Older 2 pretty independent at 14 and 16, youngest (7) at school 1 mile (15 mins) walk away 830am to 4pm. Dog too!
Would an au pair plus be ok?
DH does drop offs some mornings and would like continue to do some when he can. We both work full time.
Duties
730 to 1030 - help with morning routine, walk to school with dog (dog walk only if DH dropping DD) then tidy up, pop laundry in. Take in grocery delivery, children's ironing, occasional Hoover/dust.

Optional dog walk during day if wished, occasional errands pick up parcels, drop dry cleaning (can be on way to school)

330pm to 630pm - school pick up with dog, homework, play dates, take to sports etc, supper for youngest. One of us home by 630pm.

More time in hols but paid extra. Older girls v helpful and sports camps parental hols too.

Not sure what to offer?

West london so will include Oyster card at least for buses and mobile phone on full contract.

Driver helpful but not essential.

Good sized own room plus en suite shower room.

Also can't start till February/March as work ongoing in house and need things to be calmer first - so when should I advertise or look , agency and where?

Advice from experienced au pair families - and au pairs - would be appreciated!

HRHQueenme - thank you! Great advice! Will be sure to check those points off when trailing applications and CVs. Feeling much less twitchy now
Need to focus now on sorting out our builders so we can move forward with this.

Hi OP if you havent already done so, go to aupair world website, you dont need to join but will give you the lowdown on expectations as a host family, it also has links to uk gov website in terms on pay, hours, etc.
make sure your duties are written down and your aupair knows exactly what is expected of them, and ask what they want from a host family. Some aupairs want to be with the host family 24/7, others like their time as their own. Just make sure your ideas match up to save any grief on both parts.

Great. Thanks sagethyme.

Have a look at your car insurance now and see how much it would cost you to put an under 25 on it, there's no point in asking for one who can drive, if the insurance is astronomical and it will need to be on one of your cars or one you buy for the au pair. She wont come with one like many nannies do.

Have you considered the CM or Breakfast club & After School Club/Dog walker/Cleaner route? It sounds like more effort is required on your part, but frankly, I think it's easier in the long run. The only thing that it does rule out really is early afterschool clubs.

A good Au Pair is fab, it's just difficult to find one that isn't like having another child of your own in the house.

NeDeLaMer - thanks. I do worry about it resulting in another "teen" in the house. Will be looking at older au pairs if poss.
Ok with nannies/au pairs on insurance - done it before even for temps covering sick leave. Always feel safer when it's my car they are driving!
Dog walker and cleaner would be good (we do have a cleaner) but believe it or not the DDs school has no breakfast club, after school club or holiday club.
And no I didn't think of this all those years ago when we registered DD1!!!! I live and learn. But it's a great school and within walking distance and only fair to let DD3 have the same as DDs1&2.

Ooh. Sorry. That was long!
