Kidson-Trigg

A Family Legacy of Trust Since 1968

We are a professional, family-run business that has been a fixture of the Wiltshire and Oxfordshire property landscape for over 65 years. Founded by Martin Kidson-Trigg, our firm has built a reputation for integrity and a deeply personal approach. Today, led by Alastair and Pippa Kidson-Trigg, we continue to serve generations of families, solicitors, and estate agents who value our discretion and expertise.

Whether you are dealing with a single heirloom or the complex requirements of a full estate clearance, we provide a seamless bridge between professional property services and the global auction market.

Expert RICS Valuations & Probate Support

When it comes to property and chattels, accuracy is everything. Our team is led by Alastair Kidson-Trigg, a Chartered Surveyor and RICS Registered Valuer. We specialise in providing formal RICS Red Book Valuations for probate, tax, and matrimonial purposes.

We understand that many of our clients come to us during difficult times, such as following a bereavement. We pride ourselves on being approachable and sensitive, offering a comprehensive service that includes:

• Property Probate Valuations: Professional assessments for inheritance tax.
• Full House Clearances: Managing everything from antiques to modern interiors.
• Property Consultancy: Expert advice on sales and leasing in partnership with leading national agents.

From Wiltshire to the World: Our Global Auction Reach

While our roots are firmly in the West Country, our reach is truly international. We operate from our specialist auction rooms near Shrivenham, connecting local items with collectors in the US, Europe, and Asia through advanced online bidding platforms.

We have a proven track record of discovering hidden gems. From an Old Master painting discovered during a house clearance that sold for £300,000, to Renaissance jewellery found in a probate freezer that fetched £70,000, we have the expertise to identify and market your most valuable assets.

Our clients appreciate our flexibility—whether it's a formal appointment or a quick initial valuation via WhatsApp, we make the process straightforward and transparent.
