For the last decade, asking for a chunk of rent up front has been one of the most reliable ways for a London landlord to de-risk a tenancy. A thin-affordability tenant offers six months in advance. A foreign student's parent offers a year. A new arrival without UK credit history offers three.
That whole category of workaround was legal under the assured shorthold regime. As of 1 May 2026, under the Renters' Rights Act, it is not.
What the law actually says
The Act sets a hard cap on rent collected in advance: one month, and only in the window between signing the tenancy agreement and the tenancy commencing. Once the tenancy has started, you cannot collect rent before it is contractually due. You cannot ask for it. You cannot accept it if it is offered. You cannot quietly note it in the ledger as 'prepayment' and bill against it later.
The rule applies to every assured periodic tenancy in England — which is to say, every new tenancy granted since 1 May 2026, and every existing AST that has been converted into the new format. It applies whether the tenant is a UK national, an overseas student, a company employee on relocation, or anyone else.
Why landlords used the workaround in the first place
It is worth being honest about why rent in advance was such a common practice. Three categories of tenant made up most of the demand:
- Overseas tenants with no UK credit footprint, where the standard referencing process produced a fail.
- Self-employed or thin-file applicants whose income passed an affordability check on paper but where the landlord wanted a buffer.
- Students, particularly international students, whose parents preferred to pay the year in one transaction.
For the landlord, the appeal was straightforward: cash in the bank means the rent has effectively been received. If the tenancy goes wrong, you have already been paid. The risk of arrears collapses to zero for the prepaid period.
That risk has not disappeared. It has been moved back onto the landlord.
The workarounds landlords are trying — and which ones get you fined
Three weeks into the new regime, we are already seeing landlords and letting agents test the boundaries. Here is the practical guide.
1. 'Voluntary' rent in advance — illegal
A common pattern: the tenant 'offers' six months up front to strengthen their application. The landlord 'accepts' it as a goodwill gesture. Everyone signs.
This is illegal. The Act prohibits the collection of more than one month's advance rent, regardless of who suggested it. It does not matter that the tenant offered it. It does not matter that it is documented as voluntary. Accepting it is the breach.
2. A larger deposit — illegal
The Tenant Fees Act 2019 deposit cap is unchanged: five weeks' rent for tenancies under £50,000 annual, six weeks' for tenancies above. You cannot use the deposit envelope to absorb what used to be advance rent.
3. Inflating the marketed rent — grey area, high risk
One pattern emerging: a landlord lists a property at £2,500/month when the realistic market rent is £2,200, then privately tells thin-file applicants they will accept £2,200 if they pass referencing. This is technically not a rent-in-advance breach — but it interacts badly with the new rental bidding rules, which require the marketed rent to be a real asking price.
It also distorts the property's contractual rent for future rent-review purposes — the higher the contractual base rent, the more constrained you are by the once-per-year increase cap. We would not recommend this.
4. Guarantors — fully legal and recommended
A UK-based guarantor with strong affordability is the most straightforward legal route to take on a thin-file tenant. Guarantor referencing is the same process you would run on a primary tenant. There is no cap on guarantor income or covenant strength.
For overseas students in particular, an international guarantor service (Housing Hand, UK Guarantor, and equivalents) is now the cleanest way through.
5. Company let / corporate tenancy — fully legal
A company let — where the tenant on paper is a company rather than an individual — sits outside the assured tenancy regime entirely. Different statute, different rules. Rent in advance is not capped in the same way, and the company's covenant takes the place of the individual tenant's affordability.
This is the structure that underpins Morgan Prescott's guaranteed-rent leases. The landlord rents to us, the company, on a fixed monthly basis. We then place an occupier. The landlord receives one cheque on the same day every month, with no exposure to whether the occupier's affordability check would have passed under the new regime.
What the penalty looks like in practice
Under the new framework, councils can issue a civil penalty of up to £40,000 per breach. The penalty notice does not require a criminal conviction or a court process — the local housing enforcement team can issue it directly, with a 28-day appeal window.
The enforcement budget for the new regime is meaningful. Several West London boroughs — Ealing, Hounslow, and Hammersmith & Fulham among them — have either expanded their private-sector enforcement teams or trained existing staff against the new offences. The pattern they are looking for is straightforward: a tenancy agreement, a bank statement showing a multi-month rent payment received before the tenancy started, and the landlord's name on both.
The honest read on this for landlords
The rent-in-advance ban is, on the face of it, a technical compliance change. In practice, it removes the single most effective tool landlords had for managing tenant credit risk on a thin file. The legal substitutes — guarantors and company lets — are workable, but they require either a creditworthy third party or a step out of the assured tenancy regime entirely.
For landlords with one or two properties, the practical impact is that you will need to tighten up your tenant referencing process and lean harder on guarantor arrangements. For landlords with a portfolio, the case for moving some or all properties onto a company let / guaranteed rent structure has materially strengthened — not because the rent is necessarily higher, but because the legal architecture removes you from the regime that just changed.
Morgan Prescott was founded by former finance professionals. We model each property as a fixed-income asset and lease it from the landlord on a one-to-two-year company let. The rent is paid monthly, on the same date, regardless of who is in the property.
