What is Rental Checker?
The LonRes Rental Checker is the ideal solution for determining market rents across London. Through LonRes, agents are joining forces to create an independent, reliable source of rental data that accurately reflects the market and achieved rents, helping your clients avoid costly and time-consuming tribunals and let the property promptly for the best price.
Rental Checker confirms the need for an agent in the letting process and makes you indispensable to landlords.
No other source provides such an accurate reflection of the central London sales market. Little wonder that those leading the industry continue to regard LonRes as an essential part of their armoury.
Determining market rents
Determining market rents
The Renters’ Rights Act 2025 has raised specific concerns, namely around the rise in unreliable evidence for rent reviews and consequential distortion of the market. Following the new legislation, landlords and agents will now be required to set out an initial asking rent for their property. Importantly, they will be legally prohibited from requesting or accepting offers above the advertised rent.
Pricing inaccuracies
To follow the rule preventing accepting offers above the advertised rent, asking rents are likely to become inflated across major consumer portals like Rightmove, Zoopla, and OnTheMarket, creating a skewed representation of the market and unreliable evidence of actual rent achieved for rent reviews. The LonRes Rental Checker reports on the achieved rent, giving you accurate data.
Rise in disputes
Rent increase demands can be made annually by serving a Section 13 notice on the tenant. The rent increase demanded must be in line with ‘market’ rents.
Without access to reliable market data, tenant objections to proposed rent increases are likely to rise. Furthermore, since any extra income from a new agreed-upon rent cannot be collected retrospectively, it may be seen to be in the tenants’ interest to challenge a Section 13 notice in order to delay any increase.
Lengthy tribunal delays
A surge in disputes will inevitably see more applications to the First-tier Property Tribunal. Typically, this means a further delay in proceedings of several months.
Lost earnings
Since you will not be able to claim back lost earnings after the tribunal, landlords and agents will lose out on lost monies.
How does Rental Checker help agents?
The LonRes Rental Checker allows agents to deliver exceptional service to their clients by providing real-time, accurate market rent information based on achieved rents, ensuring timely responses and minimising delays.

Frequently Asked Questions
Your questions answered…
What if I don’t want to share all my data with the competition?
You’re not required to share everything. Start by uploading the properties you wish to share, and gradually expand your listings as you become more familiar with the system.
Agents in my area don’t collaborate, so how could LonRes benefit me?
Even more reason to use LonRes. When pitching for new instructions, you can assure prospective clients that their property will be shared with over 6,000 agents across London at no additional cost. This gives both you and your clients a distinct competitive advantage.
Isn’t LonRes just for central London? Is it really relevant to my area?
LonRes began in central London in 2000, when high property values made commission-sharing viable. As property prices across the capital have risen, the appeal of LonRes has extended beyond central London. Our network includes leading agents from across the UK, whose connection to London enhances their competitive edge and helps them secure more instructions.
Will the system just become a portal for difficult cases or unsellable properties?
Every agent has properties that sell quickly, and others that take more time. This doesn’t make them ‘problem properties.’ The benefit of LonRes is that most agents upload their listings continuously, so the system is always up to date.
