Rent review software that keeps every increase valid
Cap calculation, the notice and the copy for the RTB, in one workflow
Rentalize works out the legal maximum rent for each tenancy, drafts the rent review notice with RTB Rent Register comparables, generates the copy for the RTB alongside it, and keeps the audit trail. You serve the tenant and send the RTB copy within the 7 day limit. Across a whole portfolio, on a diary that tells you which tenancies are due.

What it is
What is rent review software?
Rent review software is the system a landlord, letting agent or housing provider uses to change the rent on existing tenancies without breaking the law. It does four jobs: it tracks which tenancies are eligible for review and when, it calculates the maximum lawful rent under the current cap, it produces the notice with the evidence the regulator requires, and it records what was served and when. In Ireland that means the lower of CPI inflation or 2%, a 90 day notice, three comparable rents from the RTB Rent Register, and a copy to the RTB within 7 days of serving the tenant. In England it means a Section 13 notice on Form 4A, because rent review clauses in tenancy agreements stopped having effect on 1 May 2026. Spreadsheets fail at this because the cap moves with published inflation data and the notice rules changed in both countries in 2026.
Two rulebooks
Ireland and the UK, handled separately
Rentalize applies the rules of the country each property sits in, so a portfolio spanning both markets runs on one system without manual translation.
Ireland
RTB rent reviews under the 2026 rules
- Cap applied as the lower of CSO CPI movement or 2% per year since the rent was last set, pro-rata and rounded down
- Nationwide since 1 March 2026, with Rent Pressure Zones abolished
- CPI-only treatment for qualifying new apartments and student-specific accommodation
- Once in any 12 month period, and never in the first 12 months of a tenancy
- 90 day notice with the calculation shown and three RTB Rent Register comparables
- Copy to the RTB within 7 days of serving the tenant
- Market rent reset tracked at the end of each six-year tenancy cycle
- Cost rental rents are reviewed separately, indexed to inflation under the Affordable Housing Act 2021 (not automated in Rentalize today)
United Kingdom
Section 13 under the Renters Rights Act
- Section 13 served date recorded, and a rent change with less than the two months' notice the Act requires is refused. Form 4A itself is prepared outside Rentalize
- Rent review and escalation clauses flagged as void, effective 1 May 2026
- One increase per 12 months, with the notice period applied automatically
- Tribunal challenge window tracked against the effective date
- Records kept in the form needed if a tenant refers the increase
Capabilities
What the rent review module does
Cap calculation
The maximum rent is computed per tenancy from the date the rent was last set, using official published index numbers rather than a figure typed in by hand. Exemptions for new apartments and student accommodation are applied from the property record.
Notice generation
The notice is produced with the current rent, the new rent, the effective date, the calculation and the comparables already filled in. No template chasing and no copy-paste between a spreadsheet and a Word file.
Comparable evidence
Three comparable rents are attached to the notice and stored with it, so the evidence that justified the increase is still there months later if the tenant disputes it.
Review diary
Every tenancy carries its own eligibility date. The diary shows what is due, what is in its notice period, and what has already taken effect, so nothing is missed and nothing is served early.
The RTB copy, ready to send
The notice and the copy for the RTB are generated together, so the copy can go to the RTB the day you serve the tenant, well inside the 7 day statutory limit. Miss the limit and the new rent does not take effect, however correct the figure.
Audit trail
Who calculated it, what the figure was based on, when it was served, and what the tenant received. Held against the tenancy record and exportable for a dispute or an audit.
The workflow
How a rent review runs in Rentalize
Six steps, the same every time, whether it is one tenancy or two thousand.
1
Eligibility check
The system confirms 12 months have passed since the rent was last set and that the tenancy is not inside its first year.
2
Maximum rent calculated
The cap is applied from the last review date to today using the published index, with any exemption taken from the property record.
3
Comparables attached
Three comparable rents are selected and stored against the review, so the notice carries its own evidence.
4
Notice drafted and approved
The notice is generated for review. Nothing is served until someone signs it off, and the proposed rent cannot exceed the calculated cap.
5
Served, and the RTB copy sent
You serve the tenant and send the RTB copy within 7 days. The notice and the copy are stored against the tenancy.
6
Effective date diarised
The new rent applies automatically on the effective date, and the rent account, statements and arrears logic pick it up from there.
Buying guide
What to check before you buy rent review software
Most systems say they handle rent reviews. These are the questions that separate a calculator from something you can rely on when a notice is challenged.
| What to check | Why it matters | Rentalize |
|---|---|---|
| Cap source | A hardcoded percentage goes stale the month inflation moves. The cap must come from the published index. | Live CSO CPI index numbers |
| Notice output | A number on a screen is not a notice. The output has to be the served document. | Notice generated, ready to serve |
| Comparables | An Irish notice without three RTB Rent Register comparables is invalid. | Attached and stored |
| Regulator copy | The RTB copy, due within 7 days of serving the tenant, is the newest requirement and the easiest one to miss. | Copy generated with the notice |
| Exemptions | New apartments and student accommodation follow a different rule. Applying the wrong one caps you too low or exposes you. | Applied from property record |
| Both jurisdictions | Irish and English rent increases are different legal processes, not one process with different numbers. | RTB and Section 13 handled separately |
| Audit trail | At dispute, you need to show the basis of the figure and the date of service. | Full history per tenancy |
| Rent account link | If the new rent is not reflected in the ledger, arrears reporting is wrong from the effective date. | Applied automatically |
Who uses it
Built for whoever serves the notice
Landlords
One property or forty. The review is the moment a small portfolio is most exposed, because an invalid notice means the increase does not happen and the clock restarts. See landlord software.
Letting agents
Reviews run across a managed book on one diary, with the evidence held per tenancy and landlord reporting attached. See letting agent software.
Housing bodies and councils
Standard rent reviews run on the same tenancy records as the rest of the stock. On the Social Housing add-on, Rentalize Core calculates differential rent for all 31 council schemes and drafts each income review for an officer to confirm. Cost rental indexation is on the roadmap, not in the product today; the free differential rent calculator covers the same 31 schemes. See housing management system.
Questions
Rent review software FAQ
What is rent review software?
Rent review software tracks which tenancies are due for a rent review, calculates the maximum lawful new rent under the current cap, generates the notice with the required evidence and any regulator copy, and keeps the audit trail. It is the difference between knowing what you could charge and being able to prove the increase was served correctly.
What is the best rent review software in Ireland?
The Irish market has several tenancy management tools with rent review features, including TenantSync and Letman. Rentalize is built around the Irish rules end to end: the cap comes from live CSO CPI data, the notice carries three RTB Rent Register comparables, the notice and the RTB copy are generated together, and the same platform runs the tenancies for letting agents, landlords and housing bodies. Compare directly on Rentalize vs TenantSync and Rentalize vs Letman.
How much can rent be increased in Ireland in 2026?
Once in any 12 month period, by the lower of CPI inflation or 2% per year since the rent was last set. The cap applies nationwide since 1 March 2026 and Rent Pressure Zones no longer exist. Qualifying new apartments and student-specific accommodation follow CPI with no 2% ceiling. Work out your exact figure with the free rent review calculator.
Do I still need a rent review clause in the tenancy agreement?
In England, no. Rent review and escalation clauses in assured tenancy agreements stopped having effect on 1 May 2026, and a Section 13 notice on Form 4A is the only lawful way to raise the rent. In Ireland the statutory process in the Residential Tenancies Act governs the review regardless of what the agreement says.
Can rent review software file the notice with the RTB?
The copy has to reach the RTB. An Irish rent review notice must be copied to the RTB within 7 days of being served on the tenant (the same day, for notices served before 14 September 2026), and if the copy is not served in time the new rent does not take effect. Rentalize generates the notice and the copy for the RTB together and keeps both against the tenancy, so the copy can go the day you serve the tenant. Sending it to the RTB is still your step.
Does it work for a portfolio spanning Ireland and the UK?
Yes. The rules applied are determined by where each property sits, so Irish tenancies follow the RTB process and English tenancies follow Section 13, from one system and one diary.
How much does it cost?
Rent review is part of the tenancy management module rather than a separate product, priced per unit under management. See Rentalize Core pricing, which starts at 199 euro a month.
