Grade 1, 2* and 2 listed buildings: what each grade means

Figures checked 28 September 2026 against Historic England's National Heritage List data and GOV.UK.

Meanings are the government's wording in the Principles of Selection for Listed Buildings. Counts are the 379,685 listed building entries in Historic England's National Heritage List for England, checked 28 September 2026.

Grade 1 vs Grade 2 listed: what is the difference?

The grade tells you how important the building is, not how strict the rules are. Section 7 of the Planning (Listed Buildings and Conservation Areas) Act 1990 requires consent to demolish a listed building, or to alter or extend it in any way that would affect its character as a building of special architectural or historic interest, and it makes no distinction between grades. A Grade II cottage needs consent for the same kind of work as a Grade I house.

Where the grade does make a difference is scrutiny. Under the government's 2021 direction on heritage applications, councils in England must notify Historic England of listed building consent applications for any works to a Grade I or Grade II* building. For a Grade II building they only have to notify it of the biggest works: demolition, knocking down a principal external wall, or removing all or a substantial part of the interior. So on a Grade I or II* home, expect even modest changes to be looked at by the national heritage body as well as the council.

What does Grade 2 listed mean?

Grade 2 (Grade II) listed means the building is of special interest, warranting every effort to preserve it. It is by far the most common grade, 348,219entries or 91.7% of England's listed buildings, so a listed house, cottage or flat you are viewing is most likely to be Grade II. It does not mean only the front is protected: the listing covers the whole building, inside and out, unless the list entry says a particular part is excluded.

What does Grade 2* (two star) listed mean?

Grade II*, said “grade two star”, sits between the other two grades. It covers particularly important buildings of more than special interest: 22,125 entries, 5.8% of the list. For an owner, the practical difference from Grade II is the extra scrutiny of consent applications described above.

What does Grade 1 listed mean?

Grade I buildings are of exceptional special interest. It is the smallest group, 9,341 entries or 2.5% of the list, and every consent application for works to a Grade I building is notified to Historic England.

What listing actually protects

Unless particular parts are excluded, the protection applies to the whole of the building, not just its exterior. A listed building also includes any object or structure fixed to it, and any structure within its curtilage, such as a garden wall or outbuilding, that has formed part of the land since before 1 July 1948.

In practice that can take in original windows, staircases, fireplaces, panelling, plasterwork, doors, floors and roof structures. Changing or removing features like these needs consent when it would affect the building's character, whether or not the list description mentions them.

Unauthorised work passes to the next owner

Doing work that needs listed building consent without it is a criminal offence under section 9 of the 1990 Act, punishable by up to two years in prison, a fine, or both. Separately, section 38 lets the council serve a listed building enforcement notice on the owner and the occupier requiring the work to be put right, and the section sets no time limit for doing so. The notice goes to whoever owns the building at the time, even if a previous owner did the work.

Before you exchange, ask the seller for the listed building consents behind any alterations, compare what you saw at the viewing with the list entry, and take your solicitor's advice on anything that looks unconsented. A Level 3 building survey, ideally from a surveyor experienced with older buildings, is worth considering for a listed home.

Insurance and upkeep

Tell your insurer the property is listed. Repairs and rebuilding may need to match the original materials and methods to get consent, so make sure the sum insured reflects that rather than a standard rebuild figure, and budget for maintenance on the same basis.

Wales and Scotland

Wales uses the same three grades. Cadw says there are around 30,000 listed buildings in Wales, with fewer than 2% at Grade I, about 7% at Grade II* and about 91% at Grade II. Scotland uses categories instead of grades, A, B and C, and Historic Environment Scotland says there are around 47,000 listed buildings there.

Check the listing before you offer

Search the address on Historic England's National Heritage List for England and read the full list entry, not just the headline, then compare it with what you saw at the viewing. Any difference is a question for the seller and your solicitor. The free HomeBuyerCheck report shows the nearest list entry with its grade and a link to it, and the Premium report from £4.99 adds listed, conservation area, Article 4 and ground-risk flags for the exact address. If the house is also in a conservation area, read our conservation area guide, and for the legal side see how to read the title register.
