New homes are built by builders. Builders are human. Humans make mistakes. It shouldn’t, therefore, come as much of a surprise to find out that your new build home isn’t exactly as you’d like it to be right from day one. 

So, how do you ensure your new home meets your expectations? A new build snagging list is the best place to start.

What is snagging?

Well, before we answer that, it might be an idea to define what a snag is first. In the most basic of terms, when it comes to building and construction, a snag is simply a defect. Snagging derives from that.

Snagging is a pretty broad term, though, as it can cover both functional and decorative aspects of the home. The vast majority of snags will be superficial, but some can be quite serious, so conducting a snagging survey and creating a snagging list is an essential part of the process.

Wait, does that mean that new build homes aren’t checked for defects?

Not at all. New build homes will indeed be checked, both by building regulation inspectors and the housebuilder themselves, but things can still get missed.

These checks are the reason why most snagging lists comprise of cosmetic issues rather than major structural problems. A cracked tile or a wonky cabinet door can be easily overlooked, whereas a huge, gaping crack in the wall will be spotted straightaway.

Who is responsible for compiling the snagging list?

In theory, you are. As the buyer, it’s down to you to point out anything you’re not happy with, but that doesn’t necessarily mean that you have to take on the responsibility of conducting the snagging survey and compiling the final snagging list for your new home. This responsibility can, and arguably should, be passed on to a third party.

You can, of course, go down the DIY route (see the section below on what to look for), but this should only be done if you’re 100% confident in your ability to spot every defect and signs of poor workmanship. If you work in the building trade yourself, this will be second nature, but others may find the process laborious and stressful.

Is a new build snagging survey worthwhile?

A lot will depend on what we covered in the section above: do you feel confident enough to compile the snagging list yourself? If you do, great! A snagging survey carried out by a professional snagging company will not be necessary. 

For everyone else, employing the services of a professional snagging firm could be a worthwhile investment. Obviously, adding yet another fee to the list when you’re buying a property is something you’d like to avoid, but a snagging survey can be well worth the extra expense.

How much does a snagging survey cost?

While this will vary from firm to firm and region to region, a professionally conducted snagging survey will usually set you back somewhere in the region of £500. Some will charge less, others more, but £500 is a good ballpark figure to give you an idea of what the service will cost.

NOTE: The above checklist should serve as a guide and is by no means complete. The defects listed here are some of the main snags found in new builds, but that doesn’t mean others won’t be present in your new home. 

If you are in any doubt about your capability of conducting an adequate snagging survey, you should seriously consider hiring a professional snagging company to carry it out for you.

Can housebuilders refuse to fix snags? 

So, you’ve conducted a new build snagging survey and handed the snagging list over to your housebuilder. All plain sailing from here, right?

Well, it should be, but that’s not always the case. Some of the defects you find may be questioned by the builder. You might think they are at fault, but they may say otherwise. They do, however, have a responsibility to put things right if the defect in question doesn’t meet the standards laid out by their warranty.

Treat your dealings with the housebuilder as you would any other negotiation and be open to a little give and take. You may not be able to get everything on your list resolved, so prioritise and push for the essentials should you hit a stumbling block. 

Another way to approach this is to preempt any problems you may have with the builder. Seek advice from your lawyer before the snagging survey begins and explain to them that you intend to instruct a new build inspection. Treat this as an adjunct to your contract and ask for confirmation in writing from the builder that all defects will be made good. 

Remember, too, that your warranty provider will be able to offer a free resolution service should communication really break down between yourself and the builder. The most common warranty provider used is the National House Building Council (NHBC) and builders will usually acquiesce if they are brought in.

That’s it for another week. We hope you found this guide to compiling a new build snagging list helpful and informative.
