The 2017 accounts for the estate show that its net asset value, or how much the estate is worth, jumped 2.9 per cent to 533.8 million pounds on the back of fewer days where properties were not rented and lower costs.
As a result, the Queen received a payment of 20.2 million pounds, a 4.9 per cent increase on the year previously. The money from the estate is used to fund the 92-year-old monarch's public and private activities.
Brexit was flagged as a "strategic risk" in the 60-page income report, which said, "Each year the duchy carries out a five-year business plan as well as preparing rolling forecasts for the year ahead.
"As part of this process, a review is undertaken of long-term trends to assess options for continued and ongoing viability of Duchy operations – this would include any outcomes from Brexit negotiations."
At 64 per cent, the bulk of the duchy's income came from commercial activities, the report said. Agriculture made up 18 per cent, followed by financial activities on 10 per cent and residential income at 8 per cent.
He said the estate's performance had been boosted by "improving tenant relations, reducing voids and increasing efficiency".
Spanning thousands of hectares, the portfolio includes rural land across eight English counties and in South Wales, 10 castles, and a number of historic buildings including on the Savoy Estate in central London and in Harrogate.
