Lease Extension Desk Valuations – Fixed Fee £450 + VAT
If you’re a flat owner preparing to extend your lease, the first step is understanding what your premium is likely to be. At Olden Property, we offer clear, RICS-compliant desktop lease extension valuations for a fixed fee of £450 + VAT, giving you reliable professional advice without the cost of a full inspection.
What Is a Desk Valuation?
A desk valuation (or desktop valuation) is a professional estimate of the premium payable to extend your lease, carried out without a site visit. Instead, we use a combination of data sources and local market evidence to assess the likely range of costs you can expect.
Every valuation is prepared by a RICS-registered valuer, following the same principles used in a full inspection, but delivered more quickly and cost-effectively.

What We Provide
For £450 + VAT, you’ll receive a concise, RICS-compliant report including:
· An estimate of the likely premium payable to extend your lease
· Analysis of lease length, ground rent, and relativity
· Reference to local market sales and yield evidence
· Commentary on marriage value and how reforms may affect you
· Guidance on next steps and how to proceed under the statutory process
Turnaround is typically within 3–5 working days once we have the relevant information.
When a Desk Valuation Is Ideal
A desktop valuation is perfect if you:
· Need an early indication of cost before serving a Section 42 notice
· Are negotiating informally with your freeholder
· Want to check whether it’s worth extending your lease now or waiting
· Are buying or selling a flat with a short lease and need to understand the impact
If a more detailed inspection is later required (for example, for Tribunal negotiations or complex ground rent structures), the desk valuation can easily be upgraded to a full inspection report.
How to Get Started
To arrange your fixed-fee desk valuation (£450 + VAT), simply provide:
· Property address
· Lease length remaining
· Ground rent payable
· Approximate flat value
Once we receive this information, we’ll confirm timescales and issue your report within a few days.
