Overview

Why NextLet

NextLet gives lettings agencies one place to run their business, from onboarding a property to renewing a tenancy. Compliance certificates are tracked with reminders before they lapse, landlords see what is happening without having to ask, and staff work from the same live data whether they are in the office or at a viewing. It is built for a market where the rules keep changing, including the Renters' Rights Act 2025.

  • Growing groupsRun several branches on one platform with each agency's data kept separate.
  • LandlordsSee compliance, rent and maintenance without picking up the phone.
  • TenantsA clear record of their tenancy and a straightforward way to raise issues.
Features

Everything it needs. Nothing it doesn't.

Property and portfolio

Onboard properties with their documents, see every portfolio at a glance, and keep landlords up to date in real time.

Compliance that doesn't lapse

EPC, Gas Safety, EICR and Right to Rent tracked against expiry dates, with reminders well before anything falls due.

Tenancies end to end

Applicants, referencing, agreements, move-ins and renewals in one flow instead of a dozen spreadsheets.

Rent and statements

Know what has been collected, what is outstanding and what each landlord is owed.

One conversation

Landlords, tenants and staff work from the same record, so nobody has to chase an update.

Tenant-scoped and audited

Each agency's data is isolated, every change is time-stamped, and deletions are soft so the audit trail survives.

Questions

Frequently asked

Which compliance certificates does NextLet track?

Energy Performance Certificates, Gas Safety, EICR electrical reports and Right to Rent checks, each against its expiry date with advance reminders.

Can I use it in a browser and on my phone?

Yes. NextLet runs in the browser and as a native app on iOS and Android, all from one codebase, so every screen behaves the same everywhere.

Is our agency's data kept separate?

Yes. Every record belongs to one agency, and the data layer applies that filter to every query automatically.
