Quick summary

You should never attempt major home projects yourself, especially those involving structural work, electricals, plumbing, or heights, as they pose safety and legal risks. For example, removing a wall or chimney, fixing a roof, or demolishing parts of your home requires professional expertise and can cost thousands of pounds, often with a timeframe of several days to weeks. Always consult experts to avoid costly mistakes or fines.

We all love some DIY and in the right circumstances, doing it yourself can help you achieve a brand new look for your home without breaking the bank. However, when it comes to major home improvement projects, snubbing your local contractors isn’t always the right choice.

When DIY goes wrong, it can not only incur huge costs to reverse the damage, it can even compromise your safety and land you with some pretty big fines from your local authority. To help you avoid these pitfalls, here are 10 home improvement projects we recommend you NEVER DIY.

Removing a wall

If you’re looking to create a more open layout, you may have decided there’s a wall that just needs to go. However, if you’ve not had an expert assess this wall beforehand, we strongly recommend you avoid going the DIY route.

Some walls are load-bearing and if this is the case, you’ll put at risk the structural integrity of your home. If you’re working with an architect, they should be able to assess your existing home designs and advise on this matter. Otherwise, you can get a structural engineer for a consultation.
