What is Listed Building Consent required for?
Any alterations which will impact on the character of a Listed Buildings, whether historic, architectural or in terms of loss of historic fabric, will require listed building consent.
General maintenance or repair carried out in a ‘like for like’ many (that means using identical materials and design is unlikely to require consent.
As the law is complex if you are in any doubt as to whether the works you intend require consent please contact the Brecon Beacons National Park’s Building Conservation Officer (details at the bottom of the page).
How do apply for Listed Building Consent?
You will need to fill in a form to apply for consent and provide a number of additional pieces of information. Applications can be made on-line via The
It is generally best to get an architect or other professional with experience of working with historic buildings to give you guidance and to help you put together a suitable application. When applying for LBC to carry out alterations or extensions you should make sure that your application includes adequate information to enable us, the National Park Authority, to fully assess the likely impact of the works on the Listed Building. If all the information is not sent the application may be delayed or even returned to you. There is no charge for a LBC application.
Pre-application advice on LBC
The National Park Authority has a pre-application scheme where you can apply for advice on the acceptability of any plans for the Listed Building prior to making a formal application. There is a small charge for this service.
The Welsh Government and Cadw both advise that pre-application advice should be sort regarding plans for alterations to Listed Buildings.
How is a Listed Building Consent application assessed?
The protection of Listed Buildings does not mean they are fossilised in time but that any changes must respect the character and special interest of the building. However, proposals to alter Listed Buildings should only be based on a proper understanding of the building and how they may affect its character. The special character of a Listed Building is precious and can be sensitive to the slightest change. It is therefore essential that any work carried out on a listed building respects the building’s historic character and its setting.
Heritage Impact Statements
From 1 September 2017 a Heritage Impact Statement will be required to support any application for listed building or conservation area consent. The Heritage Impact Statement will replace the Design and Access Statement in the application process for listed building consent.
This requirement is set out in Planning (Listed Buildings and Conservation Areas) (Wales) (Amendment No. 2) Regulations 2017 (SI 2017/638).
Guidance on preparing a Heritage Impact Statement is contained in the Cadw Document: Heritage Impact Assessment in Wales. This is aimed principally at owners and occupiers of historic assets and their agents, but it will also guide the NPA in formulating policies and considering applications for works to historic assets.
Please note that a Design and Access Statement will still be required to support planning applications within the Blaenavon World Heritage Site or in a conservation area for one or more dwellings or the creation of a floor space of 100 square metres (gross) or more are proposed. Further guidance is available in Design and Access Statements in Wales

Listed Building Consent and Ecclesiastical Exemption
Listed buildings in the ownership of six ‘exempted’ denominations do not have to follow the secular Listed Building Consent process. Instead Cadw has agreed with each denomination that they may approve alterations to listed places of worship according to controls put in place by that denomination. The basis for the exemption enjoyed by each of the approved denominations in Wales is that each has in place internal processes which provide a measure of scrutiny over proposed works at least as good as the equivalent secular controls operated through local planning authorities. This is known as ecclesiastical exemption and the ‘exempted’ denominations in Wales are:
- The Church in Wales
- The Church of England
- The Baptist Union of Great Britain and the Baptist Union of Wales
- The Roman Catholic Church
- The United Reformed Church
- The Methodist Church
Details of exemption and the controls operated by the respective
denominations are contained in ‘The Ecclesiastical Exemption (Listed Buildings and Conservation Areas) Order 1994’ and ‘The Ecclesiastical Exemption – What is it and How it Works’ respectively.
This exemption does not apply to the need for Planning Permission and
works that are planned that may affect the visual appearance of the building may require Planning Permission.
The exemption only covers the actual building used for worship not any
ancillary buildings or structures and if alterations or planned to any of the
aforementioned or within the curtilage of the building then Listed Building
Consent may be required.
If there is any doubt as to whether Listed Building Consent will be
required please contact the Building Conservation Officer on the details below.
