How housing developers can avoid demands from minerals owners

This guide relates to the law in England and Wales and was last updated in November 2013

Rights to a piece of land and to the minerals that lie underneath it can be owned by different people. It is difficult to find out who owns minerals rights, which means that housebuilders are increasingly finding out too late that other parties are claiming rights, and compensation, related to house building activity.

This is an increasingly common phenomenon because minerals rights holders are growing more confident about asserting their rights. This is an issue that housebuilders should consider from the start of a project. The best way for housebuilders to protect themselves is through insurance.

Minerals rights

If minerals end up belonging to someone other than the owner of the surface land, the minerals are 'severed'.  There are four ways in which minerals rights can be severed. These situations are:

  • the rights are sold – the rights can be sold separately to the land itself by someone who has a freehold on a piece of land.
  • the law grants them to someone else – oil, gas, coal, gold and silver are vested in the Crown
  • because of custom and practice – this is the case in parts of Cornwall, Derbyshire and the Forest of Dean
  • because of manorial rights – these are feudal rights retained by the Lord of the Manor who has previously not sold a freehold to a piece of land but a 'copyhold', which ensures some rights are retained. These are manorial rights, which include  minerals rights.

Manorial rights will disappear the next time the surface land is sold, unless the owner of those rights registered his interest against the surface owner's title. Those that were registered remain in force. The others will disappear the next time the land is sold.

Why is this important to housebuilders?

Housebuilders install foundations and subterranean services and carry out much groundwork. Any earthmoving works will involve going through or removing a minerals stratum. If that minerals stratum is owned by someone else, piercing it will be a trespass against the minerals owner. This could lead to a liability for damages or, more worryingly, could lead to an injunction to stop work on the site.

Minerals owners are increasingly asserting that any foundations work, services installation or road building amounts to a trespass. Minerals owners are better informed and more willing to raise court action than ever before. Because of this, housebuilders need to consider minerals ownership in every development.

There are cogent arguments that the surface owner has the right to carry on normal building activities, but in many cases title indemnity insurance is the best way to mitigate risk.

Problems with due diligence

Housebuilders are in a difficult position because there may be no clues from a title that any minerals have been severed. The owner/seller of the development site may not know if the minerals have been severed.

Registered Land

Housebuilders acquiring a registered freehold absolute title to a development site are still at risk of an unknown mineral severance affecting that site. Even if there is no entry registered on the title, minerals are not necessarily included in the title.

The Land Registry will sometimes put an entry on a registered title to say that the minerals are not included (or are 'excepted'). Usually the Land Registry entry will not explain the extent (type, depth and area) of the severed minerals. To find that out you would have to look at the pre-registration deeds to see if the severance was done by conveyance and, if so, for the terms of the severance. Even then, there is unlikely to be any clarity from the conveyance.

Housebuilders are at risk because the Land Registry indemnity (ie. where the Land Registry will pay compensation if the registered title is incorrect) does not apply to severed minerals within a registered title unless the registered title specifically notes that the minerals are included within it. which they rarely do.

Manorial rights to Minerals

Manorial rights to minerals will disappear the next time the land is sold unless they have been registered against the surface owner's title.

This protection does not apply to minerals titles which have been severed in any of the other ways set out above.

Rather unhelpfully, the Land Registry has said that they will continue to register notices to protect manorial rights even after an acquisition for value. The registered owner must object and apply to remove the notice.


Housebuilders should consider making three searches for each new development site:

  • a search of the index map (SIM) will reveal any separately registered minerals titles. As mineral titles are subject only to voluntary, and not compulsory, registration this will only tell you if there is a separate minerals title. It will not confirm that there is no separate title;
  • in Cheshire, brine used to be pumped from underneath the ground, leading to subsidence problems. A Brine Search is possible, and might provide clues as to whether the brine stratum within the site has been severed;
  • in the Coal Authority's opinion, any investigation of the title to mines and minerals in a coal mining area must include an inspection of the Coal Holdings Register and an analysis of the information contained in it. This is a different search to the usual Coal Authority Ground Stability Report. It costs £80 plus VAT per hour for a qualified surveyor to review the Coal Holdings Register. This provides a 'snap shot' of the ownership of minerals in coal mining areas during the 1930s and 1940s, prior to nationalisation of coal, and should provide a link between owners of minerals when they were severed from the surface and those with ownership today.

How can housebuilders protect themselves?

Title Indemnity Insurance

Minerals rights protection policies are a simple and relatively inexpensive way to mitigate the risk and should be considered in most transactions. One policy can be placed which covers the housebuilder during the construction phase and the individual plot buyers after construction.  Discounts are usually available for volume insurance.

Whilst insurance will not prevent a minerals owner asserting rights, it can negate to a large extent the cost implications of that. Housebuilders and land owners should not approach minerals owners to obtain their consent to the works or to negotiate a purchase. Insurers would be unlikely to agree protection where the rights owner has been alerted to the development.

Understand the title on offer

Thinking about the four ways in which minerals may have been severed.

  • Severance by conveyance
    (i) if the title is unregistered see if there has been a severance in the conveyances and if there has been, investigate the terms of the severance.
    (ii) if the title is registered and
    - contains an entry that the minerals are not included then ask the seller's lawyer to produce evidence of the severance (it might be by any one of the four ways) from the pre-registration deeds and investigate the terms of the severance; or
    - is silent on minerals then ask the seller's solicitors to provide the pre-registration conveyances.

    Often the pre-registration deeds have been destroyed, lost or retained on a sale of part in which case you cannot investigate the terms of the severance.

    Even if you do have pre-registration deeds, a description of the severed minerals in a conveyance is often unclear or ambiguous. Understanding which minerals were intended to be severed is difficult. Even where you can establish which minerals were intended to be severed, whether they will impact on the proposed development will depend on the detail of the engineering of the development within the ground, and whether the geology/location of minerals to be affected by the engineering includes the minerals that were severed.
  • By statute
    Coal is the main concern. The key here is to understand if coal is within the development site at depths that will involve a trespass. If so, housebuilders will need the Coal Authority's consent to any proposed movement or removal of coal.
  • By custom and practice
    Where is the development site? If it is in one of the relevant areas (Forest of Dean, Cornwall or Derbyshire) then seek legal advice and consider insurance.
  • Manorial rights
    Manorial rights to minerals generally ceased to be a problem on 13 October 2013 (when the law changed), unless the site is being acquired not for value. If there is still a concern, investigate further and inspect any deeds of enfranchisement or Inclosure Awards.

Seek an indemnity or warranty from the seller

This depends on covenant strength and it is unlikely to appeal to sellers. It is also unlikely to be transferable to plot buyers. It might work as an interim solution during the construction phase.
