Ownership
Ltd companies are not subject to Section 24. If you hold properties in a limited company, S24 doesn't apply — mortgage interest remains fully deductible. Speak to an accountant about whether incorporation is right for you.
Your Tax Band
Your marginal rate on rental income. If unsure, check your most recent tax return or P60.

Salary, pension, or other taxable income — excluding this rental property.

Good news: As a basic rate taxpayer, Section 24 is neutral for you. You received 20% mortgage interest relief before S24, and you receive a 20% credit now — the maths is the same.
