Our History

The Kidson-Trigg family has been proudly serving the region for over 60 years. It all began in  1968 with Martin Kidson-Trigg, who built a reputation for selling farms, land, and village properties, as well as operating Furniture & Fine Art Auction Rooms in both Marlborough and Swindon. Today, the family-run business continues this legacy, now operating from Auction Rooms near Shrivenham, just north of Swindon.

Every Auction has goods fresh to the market from Country House Clearance as well as individuals one off pieces. We are often covering London and the South West and locally are  covering  the areas of Marlborough, Swindon to Oxford, and surrounding villages, Ogbourne St George, Pewsey, Pewsey Vale, Ramsbury, and across to Cricklade, Fairford, Lechlade, Bampton, Burford, Witney, Wantage, and the Vale of the White Horse villages, Bishopstone, Liddington, Aldbourne, and the M4 corridor of Wootton-Bassett, and West of Swindon, including Chiseldon, Wroughton, Broad Hinton, Winterbourne Monkton, Winterbourne Bassett, and North of Swindon in the Vale of the White Horse from Swindon towards Oxford, all the villages around Wantage, Stanford in the Vale, Uffington etc,  and across to Burford and the Cotswolds. This last two auctions have seen Country House clearances across the counties of Wiltshire, Oxfordshire, Berkshire and Gloucestershire, as well as two smart Mayfair London apartments.

We’ve been part of the Marlborough and Swindon rural and village communities for over 60 years. Our connection to Marlborough dates back to the 1960s, when Martin Kidson-Trigg ran Marlborough Auctioneers (formerly Dennis Pocock). Since then, we’ve continued to support families across generations.

Whether you’re selling a single item, managing a house move, or thinking about downsizing, we’re here to help. We’re always happy to have a chat and offer guidance.

We also provide a Probate Valuation Service that many families have found helpful during challenging times. A “one stop shop service” of probate reporst, to selling the antiques & the house clearances  and the guidance on what to sell or keep and the transport logistics! We do this every week and have a blueprint service –   we aim to make the process as trouble free as possible for your family.

Our HMRC-compliant probate valuation reports and probate service is available for London and the South West and specifically Wiltshire, Gloucestershire, Berkshire and Oxfordshire
