Planning system
Isle of Anglesey County Council is in the process of upgrading the system that manages planning, building regulations and land charges. This is an essential upgrade to modernise and improve our service.
The systems will be down for a significant period, between 11 May and 26 May 2026.
Planning applications will still be available to view through the online General Public Register or MapMôn.
During this period, it will be possible to submit planning applications through:
Delays processing planning applications and consultations
Unfortunately, there will be delays processing official searches, planning applications, enforcement complaints and consultations during the period.
There may also be a delay publishing a consultation on planning applications. The statutory period for making comments will not be shortened as a result.
Isle of Anglesey County Council apologises for any inconvenience during this period.

Use MapMôn to see applications in your area
You can search and view planning and building control applications on our interactive map - MapMÔN - which also provides a comprehensive range of information related to your address and its surrounding area.
How to search for planning applications
You can search for planning applications from approximately 1984 onwards using:
- planning application reference number, such as 49C185H
- details such as ward, date valid or by key word in the application proposal
- address, by entering partial information such as entering 'new' will return all applications for New Street and New Road
- maps, with planning applications dating back to around 1947 available to view on our interactive map MapMÔN. (Historical planning applications may only contain a reference number and the descriptions are only available in English).
Planning decisions
Decisions on planning applications can be taken by either officers or elected councillors meeting at the Planning and Orders Committee, depending on the nature of the application.
We provide a webcast of the latest Planning and Orders Committee proceedings.
What you can find out
The online facility published the following information on submitted planning applications application forms, plans and supporting documentation together with the final decision (redactions are applied where applicable).
Related documents (as detailed above) will only be available for applications valid from 14 August, 2019. You can request information from applications before 14 August 2019 by filling in our online form.
The service will endeavour to provide the requested details within 15 working days of a request being received although during busy periods there may be a delay in processing your request.
The planning information displayed is not necessarily a full history of any site and it should not be regarded as an alternative to the information provided through a formal local land charges search.
Although we try to ensure the accuracy and reliability of the information provided we make no representations or warranties about the accuracy, completeness or suitability for any purpose of the information and we do not accept any responsibility for its use or reliance.
Building Control records are not public records
Building Control records are not public records which mean there is no public right to view or obtain information submitted under the Building Regulations. However, the owner of a property or a solicitor acting in the sale of the property can request to view plans or obtain a copy of completion certificates and decision notices for a specified fee.
Please note that Building Control records are kept for 16 years in accordance with the Councils’ retention policy.
