Multi-unit development
My connectionsBefore you begin
You have chosen to apply for a multi-unit development. This application applies to connections of two or more houses, apartments, or commercial/industrial units.
In order to provide you with a valid quote, the information in your application must be accurate.
For connections made after September 2018 some distribution code conditions may change, arising from the need to be aligned with European Network Codes. For more information on this see our European network codes page.
Project time frame & typical pricing
- Once you have all the documentation required, the application process should only take 10 to 15 minutes.
- We aim to provide a quotation and development agreement within 90 business days of receiving a completed application.
- Connection costs are calculated based on standard CRU approved charges detailed in the document Charges for connection to the distribution system PDF | 178 KB. More information about connection charges can be found in the ESB Networks DAC Statement of Charges PDF | 538 KB.
- For connections that support large electrical loads, it can take some time to establish the most appropriate connection method, determine costs and carry out the work required. Project timeframes will vary depending upon the extent of the work required, material lead times, and the customer’s works schedule.

**If you do not have ordnance or site plan maps, they are available for purchase on the Tailte Éireann website.
A site layout plan in a digital CAD file format
- The preferred CAD format is MicroStation DGN but AutoCAD DWG and DXF will also be accepted.
- The site layout plan must include a roof outline of the development, excluding internal building details such as furniture, fixtures, fittings, etc.

- The site layout plan must include all roadways, footpaths, kerbing, parking spaces, property boundaries and divisions within the development.
- The site layout plan must be free of contour lines, paving, landscaping, foul sewers, storm sewers and water mains. Cross-hatching/patterning should not be included on the drawing except where it is difficult to determine the outline of buildings.
- The site layout plan must be labelled with a North point and contain at least 4 points referencing the underlying ordnance survey map (e.g. existing street corners, benchmarks, etc.), as well as the ordnance survey map reference.

You will need to provide accurate details of all equipment installed at the development. You will also need to complete a table detailing a full list of final postal street names and numbers. Please note that any subsequent changes to addresses will incur additional charges.
You will need to complete a table for each unit detailing:
- The unit type (house, apartment, commercial, etc.)
- The postal address
- Capacity (MIC) required
- Phase required
- Use of time of day tariff
- Use of centralised metering
- Load demands (kW) of storage heating, if relevant
- Load demands (kW) of heat pump system, if relevant
- Load demands (kW) of electric vehicle charge point, if relevant
- Other large loads
