The short version
Most 12, 24 and 36-month business plans rise each spring by a set amount. Since 17 January 2025, Ofcom says the monthly price and any set rises must be shown in pounds and pence before you sign (Ofcom). Business contracts can include other kinds of price terms, so your contract summary is what counts.

When can you leave?
If your provider puts prices up beyond what you agreed when you signed, Ofcom says it must give you at least one month's notice and the right to leave without a penalty. If the rise was made clear when you signed, it isn't a reason to leave without charges (Ofcom).
