The New Landlord Database Explained: A Guide for London Investors
Under phase two of the Renters Rights Act 2025, the UK Government is introducing a mandatory national landlord database. Officially named the Register your rental property service, this new system rolls out regionally starting 15 December 2026. If you own a residential buy to let in London or anywhere else in England, this legislation directly affects your portfolio and introduces strict new compliance deadlines.
What is the Register Your Rental Property Service?
The new database is a mandatory government portal designed to increase transparency across the private rented sector. Initially, you are only required to register properties that are currently under let or become let during the rollout. The platform will hold key information regarding property ownership, safety certificates, and landlord contact details. In the future, this requirement will expand, and you will need to register unoccupied properties before you or your agent can market them.
Key Registration Dates for London Landlords
The rollout is strictly region specific to prevent the system from crashing. This means you’re deadline depends entirely on where your property is located, rather than where you live. While the national portal opens in December 2026 for the West Midlands, the specific mandatory window for London properties opens on 15 July 2027 and closes on 14 October 2027.
If you own a mixed portfolio with assets across different regions, you have the option to register all your active properties at once as soon as the service goes live, rather than waiting for individual regional deadlines.
How Much Does Registration Cost?
There is a mandatory annual registration fee of £65 per property. You will need to pay this fee each time you register a different property and renew it annually. However, the government has confirmed that during the initial rollout, the fee will be pro-rated so that those signing up in the earlier regions do not end up paying more.
The Crucial Detail: Your Managing Agent Cannot Complete the Entire Process
The most important operational detail for investors is that landlords are entirely responsible for starting and ending the registration process via a GOV UK One Login.
You can authorise your managing agent to provide and upload certain compliance documents on your behalf, but you cannot delegate the entire process. At Javelin Investments, we ensure all your mandatory uploads-including valid gas safety certificates, electrical installation condition reports, and energy performance certificates-are fully updated. We prepare this data so that when you log in to begin the process, we can seamlessly support the upload phase.
Penalties for Non-Compliance
The financial consequences for ignoring the new database are severe. Missing the regional deadline or failing to maintain an active entry means you risk substantial fines. Local councils are receiving specific funding generated by the database fees to identify non-compliance and enforce penalties across the private rented sector.

Frequently Asked Questions
When does the new landlord database start?
The national rollout begins on 15 December 2026 for properties in the West Midlands. However, landlords with properties located in London have a specific registration window that opens on 15 July 2027 and closes on 14 October 2027.
How much does it cost to register on the database?
The government has set the fee at £65 per property, per year. This applies to each individual property you own. During the initial rollout period, this fee will be pro rated so early adopters are not financially penalised.
Can my managing agent register my properties for me?
No. The legislation strictly requires the property owner to start and end the registration process themselves using their own government login. However, you can authorise your managing agent to step in during the process and upload specific property details and safety certificates on your behalf.
Do I need to register empty rental properties immediately?
Not during the initial rollout. At the moment, you only need to register properties that are currently let to tenants. The government will release further guidance later regarding the requirement to register unoccupied properties before they are marketed for rent.
