How it works

A guided process, without the jargon

01

Check it fits

Answer three simple eligibility questions before you reach checkout. This stage uses no AI.

02

Pay, then provide details

After verified payment, add property information and upload the lease or other useful documents.

03

Receive your report

The system cross-checks the evidence, runs deterministic calculations and prepares a downloadable PDF.

What the report brings together

Your information, the lease terms and available evidence

Important facts are labelled by source and checked for conflicts. If a difference could materially affect the estimate, the process pauses and asks you to clarify it.

Guidance, with clear boundaries

What it is

An automatically generated explanation and estimated premium range based on the information supplied and public evidence identified.

What it is not

It is not a formal or RICS valuation, legal advice, a survey, an inspection or a recommended statutory notice figure.

Using report information in a statutory notice

You may choose to use information from the report for any lawful purpose, including as one input when deciding what premium to propose in a Section 42 notice. Leaseholderguide.com does not recommend, approve or confirm any notice figure as genuine or reasonable. Any such use is entirely your responsibility and risk.

A Section 42 notice must contain a genuine opening offer and not an unrealistically low amount. Statutory landlord costs may be payable, and a tribunal or court may make a costs order where its rules permit, including for unreasonable conduct. Obtain advice from a solicitor and a qualified valuer before serving a notice.

Before you buy

What does my £75 buy?

One personalised digital guidance report for one property, with an estimated premium range, a central estimate, calculation inputs, assumptions and limitations. A completed report also provides a downloadable text briefing pack for discussion with your advisers—not professional advice. There is no subscription. No VAT is charged.

Is this a professional valuation?

No. This is an automated guidance report, with no individual surveyor or solicitor review. It helps you understand the calculation and prepare questions for a qualified adviser.

What information will I need?

The property address, lease start date and term, ground-rent schedule, and an indication of the property’s long-lease value. A copy of the lease helps cross-check the details. You can save progress and return using your private link.

How soon will I receive it?

First complete the property information after payment. The system checks the details and prepares the report when sufficient information is available. Material conflicts or missing evidence can pause generation; a fixed turnaround is not guaranteed.

Can I cancel after reading the report?

A change-of-mind cancellation right for digital content ends when supply begins if you have given the required express consent and acknowledgement and received confirmation. Your rights concerning faults or misdescription remain. See the Cancellation and Refund Policy for the full process.

Can I buy for more than one property?

Yes. Choose up to ten properties in one order at £75 each. Every property receives a separate private workspace and report.
