Any person authorised under this section may at any reasonable time enter any land in England and Wales or Scotland for the purpose of surveying it, or estimating its value, in connection with any claim for compensation under this Act for any damage to that or any other land.

See section 172 of the Housing and Planning Act 2016 for a power to enter and survey or value land in England and Wales in connection with a proposal to acquire an interest in or a right over land.

A person is authorised under this section if he is an officer of the Valuation Office of the Inland Revenue Department or a person duly authorised in writing by the Secretary of State F2, Historic Environment Scotland or other authority proposing to make the acquisition which is the occasion of the survey or valuation or (as the case may be) from whom in accordance with this Act compensation in respect of the damage is recoverable.

Subject to section 44(9) of this Act, the power to survey land conferred by this section shall be construed as including power to search and bore for the purposes of ascertaining the nature of the subsoil or the presence of minerals therein.

A person may not in the exercise of any power of entry under this Act, other than that conferred by section 43, enter any building or part of a building occupied as a dwelling house without the consent of the occupier.

A person seeking to enter any land in exercise of any power of entry under this Act shall, if so required by or on behalf of the owner or occupier thereof, produce evidence of his authority before entering.

Any power of entry under this Act shall be construed as including power for any person entering any land in exercise of the power of entry to take with him any assistance or equipment reasonably required for the purpose to which his entry relates and to do there anything reasonably necessary for carrying out that purpose.

Without prejudice to subsection (4) above, where a person enters any land in exercise of any power of entry under this Act for the purpose of carrying out any archaeological investigation or examination of the land, he may take and remove such samples of any description as appear to him to be reasonably required for the purpose of archaelolgical analysis.

Subject to subsection (7) below, where any works are being carried out on any land in relation to which any power of entry under this Act is exercisable, a person acting in the exercise of that power shall comply with any reasonable requirements or conditions imposed by the person by whom the works are being carried out for the purpose of preventing interference with or delay to the works.

Any requirements or conditions imposed by a person by whom any works are being carried out shall not be regarded as reasonable for the purposes of subsection (6) above if compliance therewith would in effect frustrate the exercise of the power of entry or the purpose of the entry; and that subsection does not apply where the works in question are being carried out in contravention of section 2(1) or (6) or 35 of this Act.

Any person who intentionally obstructs a person acting in the exercise of any power of entry under this Act shall be guilty of an offence and liable on summary conviction or, in Scotland, on conviction before a court of summary jurisdiction, to a fine not exceeding F1level 3 on the standard scale
