This page from the 1910 Land Valuation book identifies particular properties in Riding Mill. Entry 576 relates to Riding House situated at the north end of the village. The occupier is identified as Mrs Quiry and the owners as Miss Grey and Mrs Quiry. The gross annual value of the property is £60 [approximately £2,520 at today's value] while the rateable value is £51 [approximately £2,142 at today's value]. Lord Allendale was lord of the manor, and Miss Grey was one of the principal landowners in Riding Mill during this period.The 1910 Finance Act introduced a new form of taxation on property in England and Wales. The value of many properties had increased because of the introduction of new public amenities such as road or drainage systems. In such cases the property owner was to be taxed on any profit made as the result of selling that property. The tax was short-lived - it was withdrawn in 1920. By this time the Inland Revenue had assessed all properties in England and Wales. Some of the records relating to this valuation are held at the Public Record Office However, valuation books and maps which were prepared as part of the valuation process are held in County Record Offices. These comprise large scale Ordnance Survey maps and accompanying volumes that record basic details re. each property. The maps and volumes relating to many properties in Northumberland are held by Northumberland Archives Service.
