Subject: Query Regarding Premium Increase on Home Insurance Policy

Dear MyWay Team,

I hope this message finds you well.

I have noticed that my monthly premium has increased from R512 to R694, which is an increase of approximately 35.6%. However, the insured value of my property only increased from R2.9 million to R3.2 million, which is about 10.3%.

Could you please provide a detailed breakdown or explanation of the factors that led to this significant increase in my premium? I would appreciate it if you could clarify whether there were any:

Changes to my risk profile (NO CHANGE AS FAR AS I KNOW)

Adjustments in base rates

Inflationary increases in rebuilding costs

Changes in excess or policy (NO CHANGE)
