Pear - I am happy to share. I am a bit behind on paper work and am paying as I go so have not totted up, but what really matters is the pattern they see you in and how much they charge for appointments.
Basically you'll go and see them, they will order blood tests. That is LH, FSH etc on days 2-5 of your cycle (maybe a few others) and then progesterone levels on day 21. I had this done before I saw the gynaecologist on the recommendation of a nurtritionist. Cost £350 for the lot, though I was tested for thyroid function, vitamin D levels and a few other things too as the nutritionist request it.
I took this along to my first gynae appointment (though I saw her when we conceived DD - the mini pill had messed up my cycle so she knew me).
Happily these tests were everything she needed so didn't need to get that done again. Also, good news was that one of them (I can't remember the name, the one that measures the quality of the eggs you have) had improved since I saw her three years ago. So its not true these things always decline. I chalk that up to the nutritionist sorting out what I am eating.
My blood tests show my progesterone levels are not as high as they could be. So my pattern is:
See gynae around day 11 of my cycle. She scans me to see how ovulation is progressing. If it looks like I have / will ovulate she give me something to support that, and progesterone for the second half of the cycle.
This cycle the day 11 scan suggested ovulation wasn't about to happen, so she gave me something to bring that on, then I went back three days later. Scanned again, ovulation confirmed, gave me something to support post ovulation plus a higher does of progesterone for the second half of this cycle.
She charges £250 per appointment, including the scan. She was saying that she was willing to give me 'a recipe' the drugs to self administer for a few cycles so I wouldn't need an appointment with her each cycle, but now it appears I am not ovulating on a regular pattern I think she might be less up for that.
Drugs etc are included. Costs of other tests are not. Eg. if no success this cycle she wants DH to do a sperm test, will be a fee to analyse that, i'd expect about £100.
I've not been billed yet so don't know whether she will charge for both appointments last week, but I assume so.
These are central London prices, might be less outside London or the South East.
When we conceived DD I saw her for two cycles, successful second time. The all in cost of the blood tests and appointments with her was a bit less than £1000.
If we don't have success this cycle I think I will park the gynae for a cycle or two while I focus on DD stopping feeding.
I felt like we were really close and if only my progesterone levels were higher I'd have a BFP.
If it doesn't turn out that way it seems a bit silly to continue spend at this level while I'm still BF.
