Why MarketRent
One workflow for the whole rent review, connected to your CRM.
The operating system for residential rent reviews, built for letting agents in England.
Why not just fill in the form yourself?
Form 4A is a free download, and the government can change it without notice. The risk is not the form. It is everything the form does not check, evidence, or record for you.
By hand or a basic form-filler
- Miss one statutory date and the notice is challengeable. Section 13 needs two months' notice, so serving a fresh one costs another two months at the old rent, and increases are never backdated, so that income is gone
- No evidence behind the figure for the Tribunal's open-market test, so a proposed rent can be argued down
- Reviews live in a spreadsheet, so due dates slip and some tenancies quietly never get reviewed at all
- No audit trail if the increase is disputed, and the whole job waits on your most senior person
With MarketRent
- Every statutory date checked before you serve, and a notice that fails one of them blocked
- An evidence pack built for that test: comparable lettings plus an ONS-indexed reference
- Synced from your CRM, so every review is flagged as it falls due
- A locked audit trail on every review, and it is guided enough for a negotiator to run one, in about seven minutes rather than an hour
Hours back on every review
A review takes about seven minutes instead of about an hour, and the process is guided enough that anyone can run one: a negotiator, a junior property manager, whoever has capacity. For a typical agency that is about two working days a month, back for winning instructions or for the calls that need a person on the end of them.
Landlords who can see what they pay for
Under a rolling tenancy there is no signed renewal, so the rent review is the one moment a year a landlord sees what the management fee buys. Every proposed figure goes out with comparable lettings and an indexed reference from the ONS Price Index of Private Rents behind it, branded to your agency. A rent that arrives with its reasoning is easier to accept, and harder to argue down if it is ever challenged.
In published pre-Act cases, tribunals set the rent below the landlord's proposed figure in 75% of comparable cases (MarketRent analysis of published First-tier Tribunal decisions, n=667).
Built on what agents ask for
MarketRent connects to your CRM, so every review starts from tenancy data you already hold. What gets built next comes from demos, onboarding and support conversations with agencies like yours, and new releases ship every week. See all CRM integrations.
Team
Built by the founders of Fixflo
Rajeev Nayyar and Duncan Careless founded Fixflo, and spent a decade building software trusted by UK letting agencies. Rent review under the Renters' Rights Act needs the same treatment: one statutory process, run the same way by everyone, on every tenancy. An advisory board from lettings, property law and PropTech shapes what gets built.
FAQ
Frequently asked questions
The questions lettings directors ask when they are weighing it up.
Because since 1 May 2026 every assured tenancy in England's private rented sector is periodic and every rent increase runs through the statutory Section 13 process on Form 4A: at least two months' notice, once a year, challengeable at tribunal. That is a workflow change as much as a legal one, and it repeats for every tenancy, every year. Our rent reviews guide covers the rules in full.
A defective notice is open to referral: Form 4A itself invites tenants to refer a notice to the Tribunal if, for example, it gave less than two months' notice. MarketRent validates the dates before anything is served and keeps a record of every document sent.
Because when a rent is challenged the figure only holds if the evidence behind it stands up, and the better outcome is that it is never challenged. Before the Act, tribunals set the rent below the landlord's notice figure in 75% of comparable cases (MarketRent analysis of published First-tier Tribunal decisions: pre-May-2026 private-landlord cases, n=667). Under the in-force rules the Tribunal can only confirm or lower your figure, never raise it.
In published pre-Act cases the median wait from tribunal application to decision was 124 days (MarketRent analysis of published First-tier Tribunal decisions, n=604). Increases are no longer backdated, so the old rent stays payable until the decision. Being right about the figure does not get that income back.
Letting agents in England running rent reviews under the Renters' Rights Act: agents who want time back to spend on winning instructions, a clear way to demonstrate their value to landlords, and an evidence-led rent review process that avoids tribunal delays.
MarketRent was founded by Rajeev Nayyar and Duncan Careless, after more than a decade building software for UK lettings. The full story is on our about page.
