Snagging vs. Pre-Purchase Survey: What’s the Difference and Which Do You Need?

Buying a property in Ireland is one of the biggest financial commitments you’ll ever make. Whether it’s a brand-new build or a second-hand home, you’ll want to be sure that what you’re buying is safe, compliant, and free from hidden issues.

Two of the most common inspections buyers hear about are the snag list (snagging survey) and the pre-purchase survey. They sound similar, but they serve very different purposes — and in many cases, you may actually need both.

What is a Snagging Survey (Snag List)?

A snagging survey, often called a snag list, is carried out on new-build homes before you receive the keys from the builder or developer.

The goal is simple: identify defects, unfinished work, or poor workmanship so they can be fixed before you move in.

Common issues found on a snag list include:

• Cracks in plaster or paintwork

• Poorly fitted doors, windows, or skirting

• Faulty sockets, switches, or light fittings

• Heating or ventilation systems not working correctly

• Leaks, drainage problems, or insulation gaps

A snag list ensures that the builder delivers the property to the standard promised. Without one, you may end up paying for repairs later — or worse, living with ongoing defects.

What is a Pre-Purchase Survey?

A pre-purchase survey (also called a house survey or structural survey) is usually carried out on second-hand properties.

It involves a thorough inspection by a qualified building surveyor or engineer, assessing:

• Structural soundness — foundations, roof, walls, floors

• Moisture problems — damp, leaks, condensation

• Safety hazards — electrics, fire safety, accessibility

• Compliance — whether extensions or modifications meet regulations

• Maintenance issues — areas that could cost you money in the future

This type of survey is also required by most banks and lenders in Ireland before they approve a mortgage.

Snagging vs. Pre-Purchase Survey: Key Differences

Feature	Snagging Survey	Pre-Purchase Survey
Property Type	New-build homes	Second-hand / previously owned homes
Purpose	Identifies defects or poor workmanship	Checks structural integrity & compliance
Timing	Before you take possession of the house	Before signing contracts or completing purchase
Focus	Quality of finish, minor faults, fittings	Major issues, long-term risks, safety
Required By Lenders?	No	Yes (almost always)

Do You Need Both?

In some cases, yes.

• If you’re buying a new build, you’ll want a snag list to catch small but important defects.

• If you’re buying a second-hand property, a pre-purchase survey is essential for peace of mind and mortgage approval.

• If you’re buying a new build with extensions or modifications, having both can be worthwhile — the snag list covers finishes, while a survey ensures compliance with building standards.
