The complete new build snagging checklist

Moving into a brand new home is a milestone worth celebrating. The property has never been lived in, the developer has already carried out its own pre-completion quality checks, and the home has been built to meet the relevant Building Regulations requirements before handover.

A snagging list is simply the buyer's final walk-through. It gives you the opportunity to take a careful look around the property and note any small cosmetic or finishing items that may need attention before, or shortly after, you move in.

Approached methodically, the process is straightforward:

• Walk through each room and external area of the property.
• Make a note of anything that appears unfinished or requires adjustment.
• Take clear photographs as you go.
• Share your findings with the developer or site manager.

Ideally, this inspection takes place during the Pre-Completion Inspection (PCI), although many buyers also note a small number of items during the first few days after collecting their keys.

The aim is not to look for faults or assume there are problems. Instead, it is a practical final check to ensure the property is presented to the standard you expect. In most cases, only a handful of minor cosmetic items need to be addressed, and the developer's customer care team will arrange for these to be resolved as part of the handover process.

What is a snagging list and why do you need one?

A snagging list is a record of any small cosmetic or finishing items you notice in a newly built home. Once identified, these items are shared with the developer so they can be reviewed and, where appropriate, put right as part of the handover or customer care process.

Typical snagging items might include minor paintwork touch-ups, a cupboard door that needs adjusting, a small mark on a surface, or sealant that requires finishing. These are generally straightforward matters that can arise on any construction project, regardless of the size or quality of the development.

The difference between a snag and a structural issue

It's important to understand the difference between a snag and a structural issue.

A snag is usually a minor finishing item that affects presentation or day-to-day usability. Structural matters are entirely different. These are rare, relate to the fabric or performance of the building itself, and are covered through the developer's warranty arrangements and new home warranty providers where applicable. Buyers do not need to manage these informally through a snagging list.

The purpose of a snagging inspection is simply to confirm that the home has been completed to the standard you're expecting. It is not a search for problems, nor is it an indication that defects are anticipated.

On many higher-end developments, snagging lists are relatively short. Developers carry out extensive quality control checks throughout construction and before handover, meaning most buyers find themselves ticking off the majority of their checklist rather than compiling a lengthy list of issues.

If you're still weighing up the benefits of purchasing a newly built property, our guide exploring Are New Builds Worth It? explains the advantages, considerations and common questions buyers ask before making their decision.

The snagging process: When to inspect

Pre-completion inspection (PCI)

The best time to carry out a snagging inspection is during the Pre-Completion Inspection (PCI). This takes place before legal completion, when buyers are invited to visit the property and walk through it with a representative from the developer.

The PCI allows you to see the finished home before the keys are handed over and provides an opportunity to identify any minor cosmetic or finishing items that may need attention. Bringing a checklist can help ensure nothing is overlooked, particularly when you're understandably focused on the excitement of moving into a new home.

During the inspection, take your time. Open and close doors, test windows, look carefully at finishes, and make notes of anything that appears incomplete or requires adjustment. Photographs can also be useful for future reference.

After completion

Not every item will necessarily be identified before handover, and that's perfectly normal. Once you've moved in and started using the property day to day, you may notice a small number of additional items that were not obvious during the initial inspection.

This is where the developer's customer care service becomes important. Most major UK housebuilders provide a structured aftercare process following completion, giving homeowners a clear route for reporting snagging items and arranging any necessary remedial work.

Alongside this customer care period, new homes are typically protected by a structural warranty, such as NHBC Buildmark or an equivalent provider. These warranties offer additional reassurance beyond the developer's own aftercare service and provide longer-term protection for qualifying structural matters.

Rather than viewing these arrangements as separate processes, it is helpful to think of them as a layered safety net:

• The developer carries out quality inspections during construction.
• The buyer completes a final walk-through before or shortly after handover.
• The customer care team manages minor snagging items after move-in.
• The structural warranty provides longer-term cover for eligible structural issues.

In practice, your first point of contact after moving in should be the developer's customer care team. They are there to answer questions, coordinate appointments, and resolve any snagging items that arise. Most developers understand that a positive handover experience is important and will aim to address outstanding items as efficiently as possible.

DIY or professional snagging survey: Which is right for you?

There is no single right approach to snagging a new build home. Some buyers are perfectly comfortable carrying out their own inspection, while others prefer the reassurance of an independent professional report. Both options can be effective and both sit alongside the developer's own quality control procedures.

Carrying out your own snagging inspection

A DIY snagging inspection is the most common approach for many buyers. Armed with a structured checklist and a little time, you can work through the property room by room, checking finishes, fixtures, fittings and systems.

The process is straightforward:

• Walk through the home methodically.
• Test doors, windows, taps, sockets and heating controls.
• Check surfaces, paintwork, flooring and sealant finishes.
• Photograph any items you'd like reviewed.
• Share the completed list with the developer's customer care team.

For most homes, the time commitment is relatively modest. A careful inspection can often be completed in a few hours and gives buyers the opportunity to become familiar with their new property before moving in.

Using a professional snagging company

Some buyers choose to instruct a professional snagging inspector instead. This is a paid service that results in a detailed written report, typically supported by photographs and itemised observations.

Professional snagging surveys can be particularly useful for:

• Larger properties with extensive accommodation.
• Buyers who are short on time.
• Those purchasing from overseas.
• Buyers who would like an independent second opinion alongside their own inspection.

A professional survey does not replace the developer's inspections, nor does it suggest there is likely to be a problem. Instead, it provides an additional layer of scrutiny from someone who regularly assesses newly completed homes.

Which option should you choose?

The decision largely comes down to personal preference.

Many buyers are happy carrying out their own inspection using a comprehensive checklist and raising any observations directly with the developer. Others value the reassurance of having an experienced third party review the property on their behalf.

Whichever route you take, remember that the developer has already undertaken multiple quality checks before handover. The purpose of snagging is to identify any small finishing items that may have been overlooked, helping to ensure the property is presented exactly as intended.

The comprehensive new build snagging checklist

A room-by-room walk-through helps ensure you assess every part of the property consistently. The checklist below is deliberately comprehensive, not because every item is likely to require attention, but to help you inspect the home methodically and with confidence.

On most new build properties, you'll find the majority of these items meet expectations and only a small number need to be recorded for the developer's customer care team.

Exterior and brickwork

Start outside before moving through the property.

Check that:

• Brickwork is neatly finished and mortar joints are consistent in appearance.
• Pointing is complete, with no obvious gaps or missing sections.
• External walls appear clean and free from accidental marks or damage.
• Gutters and downpipes are securely fixed and aligned correctly.
• Rainwater fittings show no obvious signs of leaks or loose connections.
• Roof tiles appear uniform when viewed from ground level.
• No roof tiles look chipped, cracked, or visibly displaced.
• External paths, driveways, and paving are finished neatly and sit level.
• Garden boundaries, fencing, and gates match what was specified in the purchase documentation.

Windows and doors

Open and close every window and door during your inspection.

Check that:

• Window handles operate smoothly.
• Window locks engage correctly.
• Hinges move freely without sticking.
• Entrance, internal, and patio doors open and close without catching.
• Door furniture is securely fitted.
• Locks function correctly and keys operate smoothly.
• Glass is free from noticeable scratches, chips, or marks when viewed in natural light and from different angles.
• Frames are free from damage.
• Seals and weatherproofing around windows and doors are complete and intact.
• Trickle vents, where fitted, operate correctly.

Plumbing and heating

Run all water outlets and test the heating system if it is operational.

Check that:

• Hot and cold taps run correctly.
• Water pressure appears consistent throughout the property.
• Sinks, basins, baths, and showers drain efficiently.
• Waste pipes show no visible signs of leakage.
• Toilets flush properly.
• Radiators heat evenly across their surface.
• Thermostats and heating controls function as expected.
• Visible pipework is neatly installed and finished.
• Access panels can be opened where required.

Electrics and lighting

A simple phone charger can be useful when testing sockets.

Check that:

• All light switches work correctly.
• Ceiling lights, wall lights, and under-cabinet lighting operate as intended.
• Plug sockets supply power.
• Dimmers function smoothly.
• Smoke alarms and heat detectors are fitted where expected.
• Extractor fans in bathrooms and kitchens switch on and operate correctly.
• The consumer unit is clearly labelled.
• External lighting, if included, works as intended.

Kitchens and bathrooms

These are among the most frequently used areas of the home, so take time to inspect them carefully.

Check that:

• Worktops are free from scratches, dents, or chips.
• Splashbacks are fitted neatly.
• Cabinet doors align correctly.
• Drawers open and close smoothly.
• Soft-close mechanisms function where installed.
• Integrated appliances are present and match the specification.
• Tiling is evenly laid and neatly grouted.
• Baths, showers, basins, and WCs are securely fitted.
• Sealant around sanitaryware is smooth, complete, and continuous.
• Taps and fittings are free from damage or excessive movement.

Walls, ceilings, and paintwork

Walls and ceilings are often where buyers notice minor finishing details, particularly in a newly completed property where natural and artificial light can highlight different surfaces throughout the day. It's worth inspecting these carefully while keeping realistic expectations in mind.

Check that:

• Plasterwork appears even and smooth.
• Paint coverage is consistent across walls and ceilings.
• Surfaces are free from obvious scuffs, marks, or paint splashes.
• Cutting-in is neat where walls meet ceilings, skirting boards, architraves, and door frames.
• Corners and edges are finished cleanly.
• Skirting boards and architraves are securely fitted and free from damage.
• Decorative finishes match throughout the property where expected.

Understanding new build settlement

One point that often concerns buyers is the appearance of small hairline marks in plasterwork during the first few months of ownership.

In most cases, this is entirely normal.

A newly built home contains moisture from the construction process. As the property is heated, ventilated, and lived in, it gradually dries out and settles. During this period, minor hairline cracks can appear in plaster, around joints, or where different materials meet. These changes are a natural part of the drying and settling process rather than evidence of poor workmanship.

For that reason, homeowners do not usually need to report every fine line that appears in the months after moving in. Most developers have an established settlement policy and will explain how these items are handled through their customer care process.

It is common for developers to return once the home has fully settled, often around the end of the first year, to address minor settlement-related cosmetic issues such as filling and redecorating small hairline cracks where appropriate.

The key distinction is between normal settlement and visible finishing issues present at handover. If paintwork is incomplete, plastering is noticeably uneven, or decorative finishes are damaged, these are reasonable items to include on a snagging list. Small settlement marks that develop gradually after occupation are generally treated separately through the developer's aftercare arrangements.

Flooring

Flooring has a significant impact on the overall presentation of a new home and is relatively straightforward to inspect during a walk-through. Take time to move through each room carefully, paying attention to both the finish and how the floor feels underfoot.

Check that:

• Carpet is laid evenly, with no ripples, loose sections, pulls, or visible damage.
• Carpet edges are neatly finished around skirting boards, doorways, and thresholds.
• Hardwood or engineered timber flooring is free from scratches, dents, chips, or staining.
• Boards are fitted securely and sit evenly.
• Tiled floors are uniformly laid with consistent grout lines.
• Tiles are free from cracks, chips, or movement underfoot.
• Vinyl flooring is smooth, without bubbling, lifting, or visible joins where none should be present.
• Floors feel level when walking across them.
• Threshold strips and door bars sit flush between rooms.
• Flooring transitions are neat and finished consistently throughout the property.

A simple way to check for significant unevenness is to place a small ball on the floor and observe whether it rolls noticeably in one direction. Minor variations can be normal, particularly across larger floor areas, but obvious slopes or irregularities may be worth raising with the developer.

Lofts and insulation

The loft space may not be somewhere you'll visit frequently, but it is still worth checking during your inspection if access is available.

Check that:

• Insulation is evenly distributed across the loft area.
• Insulation appears to be laid to the expected depth.
• The loft is free from unused building materials, packaging, and construction debris.
• Roof felt appears intact and correctly fitted.
• Ventilation openings are unobstructed where visible.
• Pipework and services within the loft are neatly installed.
• Loft hatches open and close properly.
• Any boarded storage areas included in the specification are securely fitted.

Most buyers will not need to carry out a detailed technical inspection of the loft. The purpose is simply to confirm that the space appears clean, finished, and consistent with what you have been shown throughout the buying process.

Taken together, these checks provide a thorough review of the property's internal and external finishes. In most cases, you'll find only a small number of items to note, giving you confidence that your new home is ready for occupation.

How to submit your snagging list

Once you've completed your inspection, the next step is to share your observations with the developer clearly and accurately. A well-organised snagging list makes it easier for the customer care team to understand each item and arrange any necessary work.

Document each item clearly

Photographs are one of the most useful parts of any snagging list. A clear image, supported by a short description, is usually all that's needed to identify the item and determine what action may be required.

For every item you record:

• Take a clear photograph.
• Note the room or location.
• Add a brief description of the issue.
• Include any relevant measurements if they help explain the item.

The aim is to provide enough information for the customer care team to locate the item quickly without creating unnecessary complexity.

Keep the format simple

There is no standard format that must be followed. A straightforward list is often the most effective approach.

Your snagging list might include:

• Item
• Location
• Description
• Photo reference

• 1 | Kitchen | Small mark on worktop near sink | Photo 001
• 2 | Bedroom 2 | Wardrobe door requires adjustment | Photo 002
• 3 | Bathroom | Sealant incomplete behind basin | Photo 003

Whether you use a spreadsheet, document, PDF, or even a handwritten list, clarity is more important than presentation.

Share it in writing

Once completed, send the list to the site manager or developer's customer care team in writing. This provides a clear record for both parties and helps avoid misunderstandings later.

Most developers will acknowledge receipt of the list and explain:

• Which items will be reviewed.
• Whether any visits are required.
• The expected timescale for completion.
• How future snagging items should be reported after move-in.

Remember that customer care teams deal with snagging matters every day. A concise, organised list helps the process run smoothly and allows any outstanding items to be resolved as efficiently as possible.

Working with your developer

Pre-Completion Quality Checks

Before a new home is handed over, developers carry out their own inspections and quality assurance checks throughout the construction process. The property must also satisfy the relevant Building Regulations requirements before a completion certificate can be issued.

Your snagging inspection sits on top of these existing checks. It is a final opportunity to confirm that the finishes, fixtures, and fittings meet the standard you expect, rather than a substitute for the developer's own quality control procedures.

A collaborative handover

Most developers want the handover process to be a positive experience for new homeowners. Dedicated customer care teams are in place specifically to support buyers once the purchase has completed.

If you identify a snagging item, the process is usually straightforward. The customer care team will review the issue, arrange any necessary appointments, and keep you informed of progress. They can also answer questions about your home's systems, warranties, and aftercare arrangements.

Approaching snagging as a collaborative process often leads to the best outcome. Clear communication, good records, and reasonable expectations help ensure any outstanding items are dealt with efficiently.

Completion is the milestone

It's easy to become focused on small details during a snagging inspection, but it's important to keep the process in perspective.

Completion day is a milestone worth celebrating. The legal purchase is complete, the keys are in your hands, and you're ready to start enjoying your new home.

The snagging walk-through is simply a practical part of taking ownership. On most well-built homes from experienced developers, the list is relatively short, consisting of a handful of minor cosmetic or finishing items that can be addressed through the customer care process. Once those are reported, the focus can return to settling in and making the property your own.

Conclusion

Completing on a new build is a moment to enjoy. The property has been through the developer's own quality checks, meets the relevant regulatory requirements, and is ready to become your new home.

A snagging inspection is simply a practical final step in the process. By walking through the property methodically, recording any minor cosmetic or finishing items, and sharing them clearly with the developer's customer care team, you can help ensure everything is completed to the standard you expect.

On a well-built home from an experienced developer, the snagging list is often short. Most items are minor, straightforward to address, and resolved through the developer's established aftercare process. The key is to approach the inspection carefully, keep good records, and allow the customer care team to manage any outstanding items.
