Renters Rights Act — what to budget for
These are risk-based estimates, not fixed costs. Enter what feels realistic for your situation — or leave blank to see certain costs only
This section is different in character to Sections 1 and 2
Section 24 and EPC costs are largely calculable. These costs depend on your specific tenancy situation. A landlord with a stable long-term tenant carries very different exposure to one managing difficult stock or a deteriorating tenancy. Enter honest estimates — the totals below will show your position with and without this section included.
Letting agent fee increase likely
Agents carrying more admin under new periodic tenancy rules. Budget 1–2% extra on management fee — on £900/month rent: roughly £108–£216/yr
£
Extra void period risk if tenancy ends badly
S21 gone. Contested possession now takes 6–12 months in some areas. One extra void month on £900/month = £900. Only enter a figure if your tenancy situation is uncertain
£
Repairs / hazard remediation older stock
Awaab's Law + Decent Homes Standard now apply to PRS. Pre-1930 terraces, damp, ageing boilers = higher exposure. Well-maintained modern stock = low risk
£
Legal / professional costs if possession needed
Contested possession through the new system: £1,500–£4,000+. Divide by the years you think it's a realistic risk — not a guaranteed annual cost

How to read the totals below. The calculator shows two figures side by side. Certain costs (Section 24 + EPC) are real and calculable — they apply regardless of your tenancy situation. Including risk budget adds your Section 3 estimates on top. A landlord with a stable tenancy might only focus on the left column. One with an uncertain situation should look at both.
