What changed on 1 May 2026, and what LieuTenant does about it
The Renters’ Rights Act changed the rules for private tenancies in England. These are the parts LieuTenant builds in.
- Fixed terms have ended: tenancies are periodic
- New tenancies are periodic. LieuTenant won’t create a fixed term starting on or after 1 May 2026.
- Rent in advance is capped at one month
- Checked when you add a tenancy. More than one month is refused.
- Deposits are capped at 5 weeks’ rent (6 above £50,000 a year)
- Checked on every new tenancy, under the Tenant Fees Act limit.
- Tenants can ask to keep a pet, and you must reply within 28 days
- Requests come through the tenant’s login. You reply with your reasons, and you’re reminded before the deadline.
- An unprotected deposit stops most possession claims
- If you take a deposit, its protection certificate is on the tenancy’s list of documents, and a missing one is flagged.
- Rent can rise once a year, with a section 13 notice
- Keep the notice with the tenancy and update the rent when it takes effect.
LieuTenant helps you keep on top of the rules; it isn’t legal advice. Read the government’s guide to the Act.
What LieuTenant looks after
Rent
See who has paid, who is late and what each tenancy owes. Record payments, agency commission and expenses, and export reports for your accountant.
Certificates
Gas safety, EICR, EPC, deposit and Right to Rent, for every home in one list. LieuTenant emails you 30, 14, 7 and 1 day before anything is due.
Repairs and tenants
Each tenant gets their own login to see documents and payments, report repairs with photos and ask about pets. You reply and keep the record.

Why it’s free
If you let a few homes and manage them yourself, a monthly fee just to keep track of rent and certificates is hard to justify.
So the core of LieuTenant is free, for any number of homes, and it will stay free. We plan to pay for it with optional add-ons, such as rent management, for landlords who want them.
Questions
- Is it really free?
- Yes. Properties, tenancies, rent tracking, certificates, repairs and the tenant login are free, with no limit on homes. We plan to offer optional paid add-ons, such as rent management, later. The core stays free.
- Does it work in Wales and Scotland?
- The calculators work for the whole UK, except stamp duty, which covers England and Northern Ireland. LieuTenant’s tenancy rules follow the law in England; Wales and Scotland have their own.
- Where is my data kept?
- In the EU, in Dublin, Ireland. It is encrypted in transit and at rest. We don’t sell your data and we don’t show ads.
- Does it file my tax return?
- No. LieuTenant doesn’t submit anything to HMRC. You can export your income and expense reports as CSV files for your accountant or your Making Tax Digital software.
