Recommendations NIPT test London?

[AnnieStar12]

Can anyone recommend where is good in London to get NIPT test done? I've looked online and there's a huge difference in price with some for £300 and others for closer to £1k.
Confused as to what the main difference is and whether all the extra add-ons are worthwhile. Be good to get personal recommendations if anyone has any?

I'm only early so have a few a few weeks to look in to it, just thinking ahead.

Couldn't recommend The Birth Company highly enough. They're located on Harley Street. I've had 3 pregnancies using their services (both additional private scans and the NIPT), and they are fantastic.

I got mine done at the Fetal Medicine Centre. It was recommended by my private obstetrician and I found them to be excellent.
