Trusted by royal families and family offices, Parthenia Valuation Ltd provides discrete, expert valuation services across London. From complex tax litigation to lease extensions, we offer a research-led approach that prioritises pragmatic, out-of-court results for leaseholders.
We are Parthenia. Discrete, professional, and deeply experienced, we are the firm that royal families, governments, and family offices turn to when a property valuation must be beyond reproach. From Mayfair studios to historic castles, we provide the clarity and authority required for the most complex instructions.
Leading the Conversation in Leasehold Reform
We don't just follow the market; we help define it. For the last three years, we have been invited to open the annual conference at the Law Society. Our team has authored the definitive working papers on deferment rates and relativity that have been at the forefront of challenging the status quo in leasehold law.
When it comes to lease extensions and enfranchisement, we act exclusively for leaseholders. Our approach is intentionally pragmatic; we pride ourselves on achieving excellent results through negotiation, with only 3% to 5% of our cases ever needing to go before a Tribunal.
The Authority on Tax and Litigation
Our expertise is recognized by the highest levels of the profession. We wrote the residential property chapter for Tolleys, the leading authority used by accountants and solicitors nationwide. Whether you require a valuation for Inheritance Tax, Capital Gains Tax, or the Annual Taxation of Enveloped Dwellings (ATED), we offer a level of precision that stands up to the most rigorous scrutiny.
