I recently learnt that my credit score with Experian which was previously excellent has plummeted around 100 points. This happened in August. For context my husband and I bought a house, completing in early July, and in April this year I went on maternity leave. I understand a mortgage can temporarily affect a credit score but not (I didn’t think) by 100 points?! Any advice much appreciated. Reaching Experian is proving a bit of a mare.
