What Is a Registered Building on the Isle of Man?

What does the Act mean by a registered building?

A registered building on the Isle of Man is all or part of a building of architectural or historical interest for the time being entered in the Protected Buildings Register. Section 45 of the Town and Country Planning Act 1999, in the consolidated text checked on 18 October 2026, defines the term in those words. The same section defines a building to include any structure or erection, and any part of a building, and to exclude any plant or machinery comprised in a building. The register means the Protected Buildings Register maintained under section 14(1). The Department means the Department of Environment, Food and Agriculture. Endnote 145 records that the definition of a registered building was substituted by section 21 of the Town and Country Planning (Amendment) Act 2025. The definition turns on an entry that is current. A building of architectural or historical interest that is not for the time being entered in the register falls outside it.

The Department's Protected Buildings Register page, checked the same day, uses a shorter public description. It says registered buildings are those buildings and structures identified on the Isle of Man as having special architectural and/or historical interest, and that registration offers a similar level of protection to that of listed buildings in adjacent jurisdictions. The Act's own term remains registered building. The page states that there are over three hundred buildings currently entered on the register, and that building registration is an ongoing process. This guide repeats that statement as the page's own figure. It does not count the interactive district list, and it does not reproduce the list, the certificates or the site plans. The page directs correspondence about registered buildings to buildingconservation@gov.im.

Who maintains the register, and how is an entry made?

Section 14(1) says the Protected Buildings Register, previously maintained by the Department of Infrastructure, is to be maintained by the Department after the coming into operation of the Transfer of Planning and Building Control Functions Order 2015. Endnote 66 says subsection (1) was substituted by SD2015/0150. Section 14(4) requires the Department to make the register available for inspection by any person at its office free of charge at all reasonable times, and to supply a copy of any entry on payment of such reasonable charge, if any, as the Department may determine. When considering whether to enter a building, section 14(2) allows the Department to take into account the building itself, any respect in which its exterior contributes to the architectural or historic interest of a group of buildings of which it forms part, and the desirability of preserving, on architectural or historic grounds, a feature consisting of a man made object or structure fixed to the building or forming part of the land and comprised within the curtilage. Section 14(2A) allows an entry to provide that an object or structure, whether fixed to the building or not, or any part or feature of the building, is not of special architectural or historical interest. Endnote 67 says that subsection was inserted by section 12 of the Town and Country Planning (Amendment) Act 2025.

The Town and Country Planning (Registered Buildings) Regulations 2025, Statutory Document No. 2025/0202, set the procedure checked for this article. Regulation 4 requires each register entry to contain a description sufficient to identify the building, the nature of its special architectural or historical interest, including any matters taken into account under section 14(2), and the nature of any object, structure, part or feature which is not of that interest in accordance with section 14(2A). Regulation 5 requires public notice of a proposal to register, de-register or amend an entry, in at least one newspaper published and circulating in the Island or by such other means as the Department considers appropriate. The notice must allow written submissions for a period of not less than 28 days after it is first published. A copy goes to every owner or occupier, unless the land is not registered with the land registry and the Department does not know who owns it, in which case the Department must affix the notice to the building. A copy also goes to the local authority for the district and to Manx National Heritage. The Department must not make the registration decision until it has considered representations and the submission period has elapsed. Regulation 6 requires written notice of the decision, including the reasons. Regulation 6(4) says the decision does not have effect if an appeal under Part 4 is submitted, until that appeal is determined or withdrawn, or, if no appeal is submitted, until the time for an appeal has expired. Regulation 13 gives the owner that appeal. Regulation 13(2) requires it to be submitted within 3 months of the date of the decision notice. Regulation 13(3) adds a separate route if 6 months have passed from the proposal notice and no decision notice has been given.

The 2025 Regulations were made on 20 October 2025 and approved by Tynwald on 20 November 2025. Regulation 2 says that, if approved by Tynwald, they come into operation on the date on which the last of the enabling powers in the 1999 Act to make them commences. The Department's planning legislation page, checked on 18 October 2026, labels the 2025 Regulations as the text from 1 January 2026 and the Town and Country Planning (Registered Buildings) Regulations 2013 as the text before 1 January 2026. Regulation 33 revokes the 2013 Regulations. Regulation 31 keeps a narrow saving: an application for registered building consent, or an application to vary or discharge a condition, made under the 2013 Regulations before the 2025 Regulations come into operation and not yet finally determined, is dealt with under the 2013 Regulations. This guide follows the 2025 text and the consolidated Act. It does not decide which file a particular application sits in.

Which works need registered building consent?

Section 15(1) says no works may be executed for the demolition of a registered building, or for its alteration or extension in any way which would affect its character as a building of special architectural or historic interest, unless the works are authorised under Part 3. Section 15(2) authorises those works when the Department has granted written consent, called registered building consent, and the works are executed in accordance with the terms of the consent and any conditions attached under Schedule 3. Section 45 defines registered building consent, subject to regulations under section 20(2), as that written consent to works for the demolition, alteration or extension of a registered building. Section 15(3) allows consent for the retention of alteration or extension works already executed without the subsection (1) consent, or in contravention of a Schedule 3 condition, and treats those works as authorised from the grant of the retention consent. Section 15(8) says any registered building consent shall, except in so far as it otherwise provides, enure for the benefit of the building and of all persons for the time being interested in it. Endnote 77 says that subsection was inserted by section 14 of the Town and Country Planning (Amendment) Act 2025. Regulation 11(5) states the matching procedural rule: unless a condition provides otherwise, the consent applies to the building irrespective of any change of ownership or interest.

The Department's registered building consent page, checked on 18 October 2026, states that the application must be submitted to and approved by the Department before any work is undertaken, and that registered building consent is required in addition to any application for the appropriate planning permission. The same page states that there is no application fee for registered building consent, and that building regulations approval may also be required from the appropriate authority. It gives buildingconservation@gov.im as the contact for pre-application advice from the Building Conservation team. An appeal is a different payment. Regulation 18(5) requires an appeal against a consent decision, or against a failure to decide, to be accompanied by the fee prescribed for that appeal, and an election for an inquiry to be accompanied by the fee prescribed for the inquiry. This guide states no fee amount. Section 16(3) requires special regard to the desirability of preserving the building or its setting, or any features of special architectural or historic interest which it possesses, both when planning approval is considered for development which affects a registered building or its setting and when registered building consent is considered. Regulation 9 allows the Department to refuse a similar application, one not materially different from an application refused within the previous 5 years, without publishing a fresh notice. Section 15(7) says the period that regulations may specify for that kind of refusal must not exceed 5 years.

What does Manx National Heritage decide?

Manx National Heritage does not, on the texts checked, make the registration decision or grant registered building consent. Regulation 3 defines Manx National Heritage as the Manx Museum and National Trust established under the Manx Museum and National Trust Act 1959. The 2025 Regulations then give that body notice at set points. Regulation 5 requires a copy of a proposal to register, de-register or amend an entry to be given to Manx National Heritage. Regulation 6 requires notice of the registration decision to be given to it. Regulation 10 requires the Department to notify Manx National Heritage, and the local authority for the district, of an application for registered building consent and of the place and times at which the application may be viewed. Regulation 12 requires notice of the consent decision to be given to Manx National Heritage and to any other person who made representations. The decision itself, under regulation 11, is whether the Department grants or refuses consent, whether conditions are attached, and who has a right to appeal.

The appeal right is narrower than a power to decide the application. Regulation 17 says the applicant may appeal a consent decision, and so may a local authority for the area, or Manx National Heritage, if that body has submitted a relevant objection. The regulation defines a relevant objection as a written objection on a material consideration and a detrimental impact on that body's ability to carry out its functions, or on matters for which it has responsibility. Regulation 18(2) allows an appeal against a consent decision only within 21 days of the date of the decision notice. A different decision-maker appears in section 14A of the Act. If the building is owned by the Department, the Department is considering whether to enter it, amend the entry or remove it, and the Department considers that the decision should be taken by the Council of Ministers because it is of general importance to the Island or for some other reason ought not to be taken by the Department, the Council of Ministers may determine the point. If the Council determines that the building is to be entered, removed or amended, the Department must give effect to that determination. Regulation 27 adapts the notice rules for that reference.

How does a registered building differ from an ancient monument?

A registered building and an ancient monument are controls under different Acts. Section 16(1) of the Town and Country Planning Act 1999 says section 15 does not apply to works for the demolition, alteration or extension of a building for the time being the subject of a preservation order under section 11 of the Manx Museum and National Trust Act 1959, or for the time being included in the list of monuments prepared under section 13 of that Act. Section 16(2) says regulations may restrict or exclude that exception in cases the regulations specify. The consolidated planning text checked for this article does not itself name the buildings on a preservation order or on that list. The journal on ancient monuments explains those two instruments from the 1959 Act. A row on the Protected Buildings Register is a planning entry. It is a separate document from a section 11 preservation order and from a section 13 list entry.

A conservation area is a third instrument. Section 18 says the Cabinet Office shall determine which parts of the Island are areas of special architectural or historic interest, the character or appearance of which it is desirable to preserve or enhance, and shall by order designate those areas as conservation areas. Before making the order it must consult every local authority in whose district the area, or any part of it, falls, and the order must be published as soon as practicable after it is made. While an area is a conservation area, special attention shall be paid to the desirability of preserving or enhancing its character or appearance in the exercise of powers under the Act in respect of buildings or other land in the area. In the consolidation checked on 18 October 2026, section 19 is marked repealed. Endnote 84 says section 19 was repealed by section 16 of the Town and Country Planning (Amendment) Act 2025. Section 34 still applies section 31 and Schedule 5, the registered building enforcement notice provisions, to a building in a conservation area, subject to such modifications as may be prescribed.

What does a building preservation notice do?

Section 17 covers a building which is not a registered building. If it appears to the Department that the building is of special architectural or historic interest and is in danger of demolition or of alteration in such a way as to affect its character as a building of such interest, the Department may serve a building preservation notice on the owner and the occupier. The notice must state that the building appears to be of that interest, that the Department is considering entering it in the register, and the effect of subsections (3), (4) and (6). It comes into force as soon as it has been served on both the owner and the occupier. If the Department considers the case urgent, section 17(5) allows the notice to be affixed conspicuously to some object on the building, and that affixing is treated as service. While the notice is in force, sections 15 and 16 have effect as if the building were a registered building.

The notice remains in force until the later of 4 months from the date it is served or last served, or, if within those 4 months the Department gives public notice of a proposal to enter the building in the register, the final determination of any decision to enter it. Endnote 79 says that timing was substituted by section 15 of the Town and Country Planning (Amendment) Act 2025, and endnote 80 says subsection (3A), which states when that decision is finally determined, was inserted by the same section. The notice ceases earlier if the Department enters the building in the register or serves a notice withdrawing the preservation notice. Where it ceases otherwise than by entry in the register, section 17(6) says any proceedings on a consent application made while it was in force, and any consent granted while it was in force, lapse. Section 34(2) says that ending does not remove liability to be prosecuted and punished for an offence under that Part committed while the notice was in force.

What is the offence, and what can a court order?

Section 29(1) makes it an offence if a person executes or causes to be executed works for the demolition of a registered building, or for its alteration or extension in any way which would affect its character as a building of special architectural or historic interest, and the works are not authorised under Part 3. Section 29(2) makes it a further offence if a person executing works under a registered building consent fails to comply with any condition attached to it. On summary conviction the person is liable to custody for a term not exceeding 6 months or a fine not exceeding 4 times level 5 on the standard scale, or both. On conviction on information the person is liable to custody for a term not exceeding 2 years or a fine, or both. In determining the fine the court shall in particular have regard to any financial benefit which has accrued or appears likely to accrue in consequence of the offence. Endnote 96 says paragraph (a) of the penalty provision was amended by section 55 of the Interpretation Act 2015. The consolidation does not print a pound figure for level 5. Section 29(4) provides a defence only if the person proves four matters together: the works were urgently necessary in the interests of safety or health or for the preservation of the building; it was not practicable to secure that end by works of repair or works for affording temporary repair or shelter; the works carried out were limited to the minimum measures immediately necessary; and notice in writing justifying the works in detail was given to the Department as soon as reasonably practicable.

Section 39A applies where a person is convicted of an offence under section 29. Where the offence relates to demolition of, or damage to, a registered building, or to an alteration or extension which affects its character as a building of special architectural or historic interest, the court may order the person, within a period the court specifies, to restore the building to its former state. Where the Department considers such restoration would not be reasonably practicable, or would be undesirable, the order may instead require such other works as may be necessary to alleviate the effect of the works carried out without registered building consent. The order may also require the building to be brought to the state it would have been in if the terms and conditions of any registered building consent which had been granted had been met. If the person fails to comply, the court may authorise the Department to do what was ordered and to recover the costs. The register page states the practical warning in its own words: unauthorised works may result in prosecution, and there may be a requirement to reinstate the building to its former condition. Section 30 is a separate offence, for a person who apart from that section would be entitled to do an act and who, with the intention of causing damage, does or permits an act which causes or is likely to result in damage to a registered building. The penalty on summary conviction is a fine not exceeding level 5 on the standard scale. Endnote 97 says that penalty was amended by Schedule 5 to the Fines and Penalties Act 2024. Section 30 does not apply to a building referred to in section 16(1), to works authorised by planning approval, or to works for which registered building consent has been granted. The register page also states that it is the responsibility of the owner of a registered building to ensure that it is maintained in a state of good repair. Section 32 allows the Department to carry out works which appear to it to be urgently necessary for the preservation of a registered building, but not to an occupied building except to a part which is not in use, and the works may include temporary support or shelter. Section 33 gives effect to Schedule 7 so that a registered building which is in need of repair may be compulsorily acquired.

What does a map pin say about registration?

Manx Treasure Map does not record Protected Buildings Register entries, building preservation notices, conservation-area orders or registered building consents as a status layer. A marker is a public feature reference. A circle is an uncertainty area. A withheld record is a decision to publish no geometry. None of those treatments enters a building on the register, and none of them is registered building consent. The public register page checked on 18 October 2026 includes, in its Castletown district, an entry numbered 24 for Castle Rushen, with the date 03/02/1984 printed on that row. The place page for Castle Rushen is an evidence summary of a documented heritage place. It is separate from that register row, from a registration certificate and from a consent to alter or demolish the building.

Where an official source withholds a modern findspot, this article adds no point and no area. Absence of a pin is not a finding that the land has no registered building. The symbols guide explains the four publication treatments. The place-page guide explains how to read a record without treating it as a target. Before demolition, or before an alteration or extension that would affect the character of a registered building, the document that matters is registered building consent from the Department, read with its conditions. The detector journal and the excavation journal deal with written consent for a metal detector and with a licence to dig for an archaeological purpose. If an object is then found, the law and reporting page is the signpost to the reporting route. This register guide does not repeat those tests.
