Listed Buildings and Other Designated Heritage Assets

Some heritage assets are considered to be of national or even international significance. Therefore, the law imposes tight control over destruction of, or alterations to these sites. These sites include: archaeological sites, historic buildings, shipwrecks, parks, formal gardens and battlefields. They are referred to collectively as Designated Heritage Assets.

In East Lindsey, we have [last updated 17/09/2019]:

  • Listed Buildings (1457)

  • Grade I (79)

  • Grade II* (115)

  • Grade II (1263)

  • Scheduled Monuments (151)

  • Registered Park and Garden (9)

  • Registered Battlefields (1)

  • Protected Wrecks (0)

The statutory, or legal, list and descriptions for all of these can be found on The National Heritage List for England (NHLE) held by Historic England.

It is useful to note that Historic England's mapping system shows listed buildings as points, therefore it does not always highlight the full extent of the building(s) protected.

East Lindsey's mapping system shows listed buildings as polygons, this can be found on our E mapping service.  Again this may not be wholly accurate as structures such as garden walls and outbuildings may also be protected but may not be identified on this system.

The reason the online system does not give a complete picture is because Section 1(5) of the legislation for listed buildings, the Planning (Listed Building and Conservation Areas) Act 1990, states:

In this Act "listed building" means a building which is for the time being included in a list compiled or approved by the Secretary of State under this section; and for the purposes of this Act—

(a) any object or structure fixed to the building;

(b) any object or structure within the curtilage of the building which, although not fixed to the building, forms part of the land and has done so since before 1st July 1948,

shall be treated as part of the building.

This means that many buildings and structures (even very small ones) that are in the curtilage of a listed building might also be listed as well.

'Curtilage' is not defined in the 1990 Act and as a result the Courts have, on a number of occasions and on a case by case basis, interpreted whether a particular structure is in the curtilage of a listed building; and therefore included in its protection. What has emerged, formulated by the Court of Appeal in the Calderdale case, is a test based on three criteria. These tests are listed below and can be used to work out if a structure is classed as being in the curtilage:

  1. The physical layout of the principal building and the structure;

    how closely related physically and geographically are the supposed curtilage structure and the principal listed building, bearing in mind that the curtilage can in some circumstances extend to buildings or structures that are some distance away?

  2. Their ownership, past and present; and

    was the structure in the same (or linked) ownership as the principal listed building?

  3. Their use or function, past and present.

    was the use of the structure related in some way to the use of the principal listed building? The House of Lords, in the Debenhams case, subsequently emphasised that the use of the structure must be "ancillary" to the use of the principal building.

These criteria should be applied to the facts as they were at the date of listing, and all three should be met for a building/structure to be considered curtilage. As cases come forward this position may change, therefore it is advisable to check the latest case law before considering if a building or structure should be deemed curtilage.

Carrying out unauthorised works to a listed building is a criminal offence liable to a fine and imprisonment. For more information please visit our FAQs.

With the exception of Scheduled Monuments and Protected Wrecks, all designated heritage assets are dealt with by the Local Planning Authority. Therefore, it is likely you'll need to speak to our Planning Service.

For advice on Scheduled Monuments please also contact Historic England who provide advice on Scheduled Monument Consent.

Historic England also issue the licences needed to work on or near Protected Wreck Sites.
