Renting in Ireland has never been more competitive or complex, and for many tenants, rent increases are one of the biggest concerns in 2025. Whether you’re renewing your lease, negotiating with a landlord, or preparing a tenant resume to apply for a new home, understanding how rent increases work is essential.
Recent legislation, changes in Rent Pressure Zones (RPZs), and inflation-linked caps mean that staying informed can directly impact your rental journey and financial planning.
In this guide, we’ll walk you through everything tenants in Ireland need to know about rent increases this year — and how tools like Tenantin.ie can help you stay prepared and stand out in a crowded rental market.
How Rent Increases Are Regulated in Ireland
If you’re currently renting in Ireland, your landlord can’t increase the rent without following strict rules. The Residential Tenancies Board (RTB) outlines the legal process a landlord must follow, including:
- Notice Period: A landlord must give 90 days’ written notice before increasing rent.
- Frequency: Rent can only be increased once every 12 months.
- Market Rate: Outside RPZs, rent must reflect local market rates and be justified with comparables.
- RPZ Rules: Inside Rent Pressure Zones, rent increases are tightly controlled and linked to inflation (HICP index).
Understanding these rules helps you plan your budget and gives you more confidence when discussing your rental agreement.
What Changed in 2025: A Nationwide RPZ
In 2025, new legislation declared that the entire country is now a Rent Pressure Zone. This has major implications for every tenant:
- Rent Increase Cap: Rent increases are now capped across the country using a fixed formula tied to inflation.
- No More Market-Rate Increases: Even in previously unregulated areas, landlords must now stick to the RPZ formula.
- Higher Transparency: Rent increases must be registered and justified through the RTB.

How to Respond to a Rent Increase
When you receive notice of a rent increase, take these steps:
- Review the Notice: Check that the notice meets the RTB guidelines.
- Request Comparables: You’re entitled to ask for evidence supporting the increase.
- Use Your Rental History: A strong rental history can be a powerful tool in negotiating rent.
- Seek Help: If you believe the increase is unlawful, you can dispute it through the RTB.
Remember, landlords must follow proper procedures. If they don’t, the increase may be invalid.
The Role of a Tenant Resume During Lease Renewals

A tenant resume is more than a tool for applying to new properties — it also gives you leverage when negotiating a lease renewal.
Your resume can include:
- Proof of consistent payments
- Strong references
- Employment details
- Your rental history
When a landlord sees that you’re reliable and professional, they’re more likely to keep you on — and potentially reconsider an aggressive rent increase.

Inflation, Cost of Living, and Future Trends
Ireland’s rental market is evolving fast. With inflation easing slightly but housing demand still high, tenants should expect modest annual rent increases.
Key trends to watch in 2025:
- Sustained pressure on supply: More renters than homes.
- Short-term lets tightening: More properties returning to long-term rental pool.
- Regulatory clarity: Government is cracking down on unregistered increases.
This means it’s more important than ever to track your rental history and have your documents ready when applying or renewing.
Why Your Rental History Matters More Than Ever
Landlords and agencies increasingly want proof of your track record. Having an organised rental history:
- Builds trust with landlords
- Speeds up the application process
