With rising costs placing pressure on UK homeowners, many are taking matters into their own hands and turning to TikTok for DIY home improvement inspiration. Popular hashtags such as #DIYProject have sparked significant interest, with over 1.9 million posts showcasing budget-friendly renovation tips and innovative solutions.
As the platform continues to serve as a hub for creative ideas, we examined some of the most popular DIY home renovation videos on TikTok and their potential impact on home insurance.
As a specialist home insurance broker, we can vouch that while many of these viral home renovation projects may seem enticing, they may invalidate your home insurance, making it important to understand how to avoid costly mistakes when attempting TikTok-inspired DIY projects.

The trends likely to impact your home insurance
Adding an arch to your walls
Arches are a major trend in interior design for 2025, whether in hallways, doors or windows.
This stylish feature has also gained popularity in the TikTok DIY world, with one viral video showing a DIY arched doorway generating a staggering 51.6 million views and 4.9 million likes.
While arches can add significant aesthetic appeal, they may also introduce potential risks to your home insurance cover. If the wall being altered is load-bearing, creating an arch could compromise the structural integrity of your home, leading to potential expensive consequences. For example, if your DIY project causes or exacerbates structural issues, insurers may refuse to pay for repairs or related claims.
Bathroom makeover
Complete bathroom renovations have also been really popular on TikTok with DIYers attempting a full makeover.
A video with over 18.1 million views and 1.8 million likes highlights a user who mistakenly thought she could give her bathroom a “quick facelift”. While DIY upgrades may seem like an easy way to save money, it’s crucial to notify your insurer of major renovations in high-cost areas like kitchens and bathrooms.
These upgrades can increase your home’s value, and you need to ensure you have proper coverage. Failing to inform your insurance company about these types of changes could invalidate your home insurance policy, leaving you unprotected against risks such as fire, theft or water damage.
Arched storage spaces
Another popular DIY renovation hack on TikTok involves creating arched niches in your walls to create more storage space, with one video attracting 35.8 million views and 3.6 million likes.
While these features are undeniably striking and practical, it’s important to remember that DIY work can void your insurance if it’s not done properly. Most policies won’t cover damage caused by self-inflicted construction errors or accidents that occur during a non-professional renovation. This type of work could also accidentally damage electrical wiring or plumbing within the wall and you may face costly repairs that your insurer is unlikely to cover.
