Key Strengths.











Expert Witness.

In formal disputes and litigation our surveyors act as Expert Witness on property valuation matters having previously given evidence on behalf of clients before the First Tier Tribunal (formerly known as the Leasehold Valuation Tribunal), County Court and High Court ensuring stringent adherence to Civil Procedure Rules.


We are members of and regulated as a practice by the Royal Institution of Chartered Surveyors (RICS),  members of the Association of Leasehold Enfranchisement Practitioners (ALEP) and registered practitioners on the government sponsored Leasehold Advisory Service.

Roshan is responsive and a real expert in the field. He turns around his reports in a timely fashion and always manages to achieve effective and acceptable results for my clients. A real asset to the profession.

We have always found Blakes to be professional, helpful and approachable in all our dealings. In addition, the reports received are comprehensive and prompt even when we find ourselves having to give “last minute” instructions.

Richard Turney, Partner, Rose & Rose Legal, KT1.

Blakes agreed an excellent settlement allowing the matter to be completed without referral to the Tribunal, acting in my best interests and ensuring my financial interests in the freehold were protected. I would highly recommend using Blakes.

John King, Barrister, 9 Bedford Row, WC1R

Blakes negotiated with the freeholder, I'm confident was a much better price for the lease extension than I could have got to myself, I have since recommended Roshan & Blakes to our own clients.

May I also take this opportunity to thank you for your help and services in this matter. From our first phone conversation, to your obviously excellent skill in negotiation, you have made this a stress free experience for me with an excellent result.
