Public evidence
Reader reports, press coverage and official sources can make the register more useful — but only when handled carefully.
This is the place for factual notes about whether public access works in practice. It is not a wall of shame, and it is not a place for gossip about owners.
The register exists because owners receive tax relief in exchange for public access. Journalists and Parliament have both raised long-running problems: outdated contacts, opaque appointment systems, low visit numbers and uncertain compliance. At the same time, many owners and agents do arrange visits properly once the right contact is found.
So our approach is deliberately narrow. We collect practical evidence that helps visitors: broken emails, no response after a reasonable request, access successfully arranged, updated contacts, published open-day links and official or press coverage of the scheme.
We only use labels when they are useful, dated and sourced. Forum comments and social posts can suggest where to look, but they are not enough on their own.
The baseline below is scheme-wide context from reporting and official history. Entry-specific notes are shown only where a source names the property directly, or where reviewed visitor reports establish a factual pattern.
The Guardian reported in 2013 that its survey contacted 30 cases but secured only five viewing appointments. The article also described agents who did not know the owner or item, and one owner who worried a request might be a security risk.

The Financial Times reported in 2025 that a sample of 100 object entries had many incorrect or unverifiable contacts, including retired, dead or otherwise unsuitable contacts, and items that had been stolen or sold. It also reported that many owners were cooperative once the correct contact was found.

The Open Spaces Society reported in 2025 that HMRC would not appeal a First-tier Tribunal order requiring redacted heritage management plans for named estates to be disclosed. The case matters because those plans can show what access and conservation obligations were agreed in return for tax relief.

A 1999 Public Accounts Committee report said improved publicity had not increased visits, that 20% of appointment cases took more than four weeks, and that land/building compliance visits had slipped badly: fewer than 50 of 130 expected inspections took place between 1995 and 1997.

The same Public Accounts Committee report said that, among National Audit Office cases where owners were not advertising in the expected guides, the Revenue found a quarter did not have adequate publicity arrangements. This supports flagging entries where publicity or contact routes are weak.

In a 1999 Lords debate, the minister said prior appointment was originally intended as a last resort for chattels, but had become the first resort in too many cases. He said the public, not only scholars, had to have access to the exempt items.

Tax Adviser recounts Mark Thomas's 1997 test of the scheme through the Sir Nicholas Soames mahogany-buffet case, presented as an example of exempt items effectively enjoyed privately while supposedly available to the public. The source says the 1998 rules tightened access and quality requirements.

The Independent reported in 1999 that, before reforms, the list was unpublished and access could be obstructed. It cited examples including requests for proof that visitors were art students and a sports car on the list that was taken overseas and crashed.

The Guardian reported in 1999 that owners' names were not listed for works in a tax-exempt exhibition and that a large share of exempt items was held by a small number of owners. This is scheme-wide context about transparency, not an entry-specific finding.

In 2013 written answers, HMRC said information about visitor numbers to tax-exempt heritage assets was not available and that it did not record public visits to each asset. That makes independent access reports more important.

A 2021 WhatDoTheyKnow request asked how many cases HMRC investigated where withdrawal of conditional exemption was considered and how many exemptions were withdrawn. HMRC maintained a confidentiality refusal but later said the answer to both questions for all requested years was fewer than five.

The Scottish Affairs Committee said it was hard to assess value for money without better transparency on tax forgone. It also questioned whether access undertakings add public value in Scotland where broad access rights already exist.

GOV.UK says appointment access should normally be offered as soon as reasonably practical, with a choice of at least three weekdays and two weekend days within four weeks, usually between 10am and 4pm. This is the benchmark used when assessing visitor reports.
