Listed building consent is a separate permission for work that would affect the character of a listed building, inside or out. There is no fee for it and the council has eight weeks. Doing the work without it is a criminal offence, and there is no time limit on enforcement.
One half of a Grade II listed Regency terrace in a Leamington Spa conservation area, divided into two homes a century ago. The owners had bought part of the garden next door, wanted to enclose it, and wanted more light on the ground floor.
Phase one was a garden wall. On an unlisted house that is barely a project. Here the protection runs to the curtilage, so the wall, an extension to an existing outbuilding and a new pedestrian gateway all needed listed building consent in their own right. It was granted on 25 April 2024, the materials condition was discharged in September, and the wall was built that summer in reclaimed brick.
Phase two was an orangery of about eight and a half square metres off the music room. The heritage question was the opening. Cutting through the rear wall of a listed house removes historic fabric, and the wider the hole the more of it goes. The conservation authority asked that the opening be kept to double-door width, so less was lost and the change stayed reversible. The drawings were revised and consent followed.
The householder application and the listed building consent were granted on the same day, 11 December 2024. That is not automatic: they are separate applications answering separate tests. The garden is enclosed and in use, and the owners are taking the orangery forward themselves.
Nothing changes from the street. All of the work is at the rear and along the boundary, in materials taken from the house rather than added to it, so the terrace and its neighbours see no change at all.
The general lesson is the wall rather than the orangery. Most owners expect an extension to need consent. Far fewer expect a garden wall to, and the provision that catches it is the same one that catches a coach house, a privy or a set of gate piers that have stood in the grounds since before 1 July 1948.
The two applications landing on one day is worth noticing too. Nothing requires it. They were prepared together, submitted together and answered the same heritage case from two directions, which is the only reason they moved at the same speed.
A listed building in the town centre, its upper floors taken from offices to flats. The listed building consent was granted first time. The planning application beside it was not: that one was withdrawn, and a revised scheme was granted the following year. One building, two tests, two different answers.
A Grade II listed Regency building on the Promenade, with two floors stranded above the gallery by an unsafe stair. Listed building consent covered a new stair, the reordering inside, and one external change, a new fascia sign. Four floors are now in use and the work is certified complete.
A listed Northamptonshire farmhouse, with consent for a side extension and a glazed link, and a further consent two years later. The later one arrived with conditions attached to the detail: a sample panel, a roof sample, the eaves, verge and joinery details, the glazed link, the landscaping, and the rainwater goods. Six conditions, all discharged in 2021.
A former chapel standing between listed neighbours in a conservation area. Because the chapel itself is not listed, no listed building consent was needed at all. The planning application still had to answer for the setting of its neighbours, and it was granted at committee over twelve objections.
The same listed building, twice. The first scheme took down a flat-roofed extension and replaced it, with internal alterations, and it needed listed building consent, which was granted. The second put a pitched roof over an existing garage: planning permission was granted for it, and the council determined that listed building consent was not required at all.
Every listed building consent we apply for in our own name is a matter of public record on a council register. 84 have been granted, across 16 planning authorities, and the earliest of them was applied for in 2001.

→ Start a conversationEvery listed building in England has an entry on the National Heritage List for England, and anyone can search it for nothing. The entry gives the grade, the date the building was listed, and a description of it.
The description is the part people misread. It is a reference note, not a schedule of what is protected. Historic England is explicit that a list entry description does not define or limit the extent of the listing, and that the interior is covered even where the entry never mentions it. A three-line entry and a three-page entry protect the same amount of building.
It is also worth checking whether the listing is yours at all. A house next door to a listed one is not listed. What does cross the boundary is setting: an application for development in the setting of a listed building carries a statutory duty of its own, so the heritage argument can reach a site that needs no listed building consent whatsoever.
If the entry is hard to find, search by postcode as well as by address. Buildings are sometimes listed under a former name or a former occupier, and a terrace is frequently listed as one entry covering several numbers, so an address search on your own number can return nothing while the building is plainly listed.
A locally listed building is a different thing again, and so is a building that sits only in a conservation area. Neither needs listed building consent. Both can still shape what a council will accept, and both are answered lower down this page.
Listed building consent is the one everybody knows about. The same Act carries three more, and two of them answer the question consent cannot: whether you need it at all.
Required before the demolition of a listed building, and before any alteration or extension that would affect its character as a building of special architectural or historic interest. There is no application fee, and the council has eight weeks from a valid application to decide it.
A formal answer to the prior question of whether the works need consent in the first place. The owner describes the proposed works, the council determines whether they would be lawful without consent, and the certificate settles it. Section 26H of the Act.
Any person may ask the Secretary of State to certify that a building is not intended to be listed. A certificate blocks listing, and blocks a council's building preservation notice, for five years from the date it is issued. Section 6.
A written agreement between an owner and the council which can itself grant listed building consent for specified works, with conditions, for the life of the agreement. Others can join it, including Historic England. Section 26A.
The framework everybody quotes is not where this starts. The duty is in the Act. In considering whether to grant listed building consent, a council must have special regard to the desirability of preserving the building, its setting, and any features of special architectural or historic interest that it possesses. That comes before any policy.
Policy then sets the weight. Great weight is given to conserving a designated heritage asset, and the more important the asset the greater that weight. Any harm to its significance requires clear and convincing justification. Substantial harm is refused unless it is necessary to achieve substantial public benefits that outweigh it, and less than substantial harm is weighed against the public benefits of the proposal.
Who reads it depends on the grade. A council must notify Historic England of every listed building consent application affecting a Grade I or Grade II* building. For an unstarred Grade II building it must do so where the works amount to demolition, to the loss of a principal external wall, or to the loss of a substantial part of the interior. Most Grade II householder work is therefore decided locally, by a planning officer advised by a conservation officer.
Consent almost never arrives clean. Conditions attach to the detail, and they have to be discharged by separate application before the work they govern can proceed.
The thresholds behind that Grade II test are numerical, and a project can cross them without anyone intending demolition. Retaining less than half the surface area of an elevation counts as demolishing a principal external wall. Removing a staircase, a load-bearing wall, a floor structure or a roof structure counts as demolishing a substantial part of the interior.
Where any part of a listed building is to be demolished, six national amenity societies must be notified as well: the Society for the Protection of Ancient Buildings, the Ancient Monuments Society, the Council for British Archaeology, the Georgian Group, the Victorian Society and the Twentieth Century Society. Any of them may object, and an objection changes how the application is handled.
Carrying out work that needed listed building consent, without it, is a criminal offence. On conviction on indictment the maximum is two years in prison and a fine, and in setting the fine the court is directed to have particular regard to any financial benefit the offender gained from the offence.
Nothing in the Act puts a time limit on it. Unauthorised alterations to a listed building do not become lawful with age, which is why a breach committed two owners ago is still the current owner's problem. A council can serve a listed building enforcement notice requiring the work to be undone whenever it finds it.
There is a way back. An application can be made for consent to retain works already executed, and where it is granted the works are authorised from the date of that grant. Read that carefully: it makes the building lawful going forward. It does not reach back over the period when the work was unauthorised.
In practice this surfaces at sale. A buyer's solicitor asks for the consents, they are not there, and the sale stalls while indemnity insurance or a retrospective application is arranged. Finding out before the work starts is a great deal cheaper than finding out at exchange.
The offence is not confined to the owner. It catches the person who executes the works and the person who causes them to be executed, so a contractor is exposed as well, which is why a good builder asks to see the consent before starting.
There is a defence and it is narrow. All four of its limbs have to be made out: that the works were urgently necessary in the interests of safety or health or for the preservation of the building; that it was not practicable to secure that by repair or by temporary support or shelter; that the works were limited to the minimum measures immediately necessary; and that written notice justifying them in detail went to the council as soon as reasonably practicable.
Not if they are genuinely like for like. The test in the Act is whether the work would affect the building's character.
That test cuts both ways. Replacing a broken slate with a matching slate does not affect the character of the building as one of special architectural or historic interest. Replacing a slate roof with a concrete tile one does, even though both are roofing a roof. The same goes for joinery: repairing a sash window is repair, while replacing it with a different section or a different material is not. Where the answer is genuinely unclear, the council can be asked to determine it formally rather than for an opinion by email, and a formal determination is worth having in writing before a builder starts.
Not what needs consent. Grade I, grade II* and grade II are all listed, and the same works need the same consent at every grade.
What moves with the grade is how much a loss weighs once the application is being judged. Substantial harm to a grade II building should be exceptional. Substantial harm to a grade I or grade II* building should be wholly exceptional, which is a materially higher bar and not the same test worded more strongly. So an alteration accepted on a grade II terrace can be resisted on a grade I building, not because the rules differ but because there is more to lose. The grade changes what is realistic to propose, never whether you have to apply.
Three years, unless the consent itself says otherwise. The deadline is on starting the works, not on finishing them.
The Act requires a consent to carry a condition setting the period within which the works must begin, and where no period is specified, three years from the date of the grant applies automatically. An authority can set a longer or shorter period where it has a reason to. Once the works have lawfully begun the deadline has done its job. It is worth reading the condition rather than assuming the default, because a consent granted alongside a planning permission can carry a different period from the permission beside it.
Yes, to the Secretary of State, and the period is six months from the date of the decision.
The same right applies where the council has not decided the application within its eight weeks. Six months is generous by planning standards, which is worth knowing because it leaves room to weigh the alternative. A refusal on heritage grounds usually turns on a specific point of fabric, and a revised application answering that point can be quicker and more certain than an appeal. The six months can be extended at the Secretary of State's discretion, but nothing obliges him to allow it, so the date on the decision notice is the one to diary.
Some do and some do not, and none of them removes the need for listed building consent.
The two systems run separately. A rear extension can still be permitted development on a listed house, which means no planning application is needed, and it will still need listed building consent if it would affect the building's character, which an extension almost always does. Other rights are switched off outright. The class that covers outbuildings, sheds, garden rooms, swimming pools and enclosures expressly excludes anything within the curtilage of a listed building, so a garden room a neighbour could put up without asking needs a planning application here.
A local list carries no listed building consent at all. It is a material consideration, not a separate permission.
A locally listed building is a non-designated heritage asset. National policy says the effect of an application on its significance must be taken into account, and that a balanced judgement is required having regard to the scale of any harm or loss and the significance of the asset. That is a real test and it is regularly the reason a scheme is refused or reduced, but it is weighed inside the ordinary planning application rather than in a consent of its own. A local listing does not remove permitted development rights, although an Article 4 direction over the same building would.
In law yes, with consent. In practice a total loss needs a case that very few schemes can make.
Demolition is treated differently from alteration in the Act. Consent for an alteration or an extension is needed only where the work would affect the building's character, whereas consent for demolition is needed full stop. Policy then sets the bar: an authority should refuse consent for substantial harm or total loss unless it is necessary to achieve substantial public benefits that outweigh it, or a narrow set of conditions about viable use and marketing is met in full. Partial demolition inside a larger scheme is the commoner question, and it is the point at which more consultees join in.
