There are some home improvement projects even the most experienced DIYers should avoid taking on themselves. In this blog, we’re sharing the tasks you should always leave to the pros.


1. Electrical work

While it can be tempting to take on the electrics yourself, it can be extremely dangerous if something goes wrong. Incorrect wiring can lead to fires, damage to appliances or even electrocution.

What’s more is you must ensure that electrical work complies with Part P of the Building Regulations. You may be allowed to carry out some minor electrical work yourself, such as changing sockets or switches, but bigger jobs can be much more complicated. Building regulations state that all notifiable electrical work must be carried out by a registered competent person so, unless you have the knowledge and qualifications to work on electrics yourself, always hire a professional.

2. Structural changes

Altering load-bearing walls can compromise the structural integrity of the building so you shouldn’t attempt to do this yourself. The last thing you want is your ceiling to fall through.

Any structural changes to your home, including the removal of internal walls, should be carried out by professionals.

3. Plumbing

While there’s nothing stopping you from plumbing in a new bathroom or dishwasher, even a small mistake could cause huge amounts of water damage. Whether there’s a leak that goes unnoticed, causing untold damage behind-the-scenes, or a major flood, controlling and rectifying water damage is no small task. That’s why it’s always best to ask a plumber to help with any repairs or installations.

4. Rendering or plastering

Plastering can be tricky to master, and it’s often best left to a professional who can complete the job efficiently. Plastering or rendering incorrectly could result in a poor finish and even cracks in the walls which can be tough to repair.

5. Roof repairs

Even if you can brave the heights, repairing or replacing a roof can be dangerous and you’ll need specialist knowledge and equipment to complete the job safely. Plus, if the job’s not done correctly, it could lead to damp or even structural damage. You could end up causing much more damage in the long run by doing it yourself. Why not hire a roofing contractor to get the job done safely and efficiently instead?

6. Installing or repairing gas appliances

It’s illegal to work on gas fittings unless you are a Gas Safe registered engineer. And there’s a good reason for this. Badly fitted gas appliances can expose your home and your family to a number of risks such as gas leaks and carbon monoxide poisoning or even potential explosions.

This one really is non-negotiable – always instruct a Gas Safe registered engineer to carry out any gas works in your home. Our top tip is to always check the engineer’s credentials and ID card to ensure they are on the Gas Safe register before allowing them to commence work in your home.

7. Asbestos removal

If you have an older home (constructed pre-1999), there’s a chance your home could contain asbestos. Fortunately, asbestos materials are only dangerous once disturbed so it’s only a real cause for concern if you’re planning renovations that could cause any damage to materials that may contain asbestos.

If you do need to disturb asbestos materials, it’s important you never do this yourself. Call in a licenced professional to inspect your home and remove the asbestos.

8. Carpet fitting

It’s pretty difficult to fit a carpet if you don’t have the skills or the specialist tools to carry out the job. You could end up spending more cash than you bargained for if you don’t cut the carpet to exactly the right size. Save time, expense and hassle by paying a carpet fitter to complete the job instead.

9. Installing a window

It can be difficult to install a window, which is why you’ll need to make an application to Building Control before you can even attempt to replace a window yourself. This is often not worth the hassle.

Lots can go wrong during the process of removing the old window, installing the new one and sealing it. And, unlike some other DIY mishaps, the ramifications of a poorly fitted window can be far-reaching. For a start, it’s a potential hazard should the window crack, shatter or fall. It could also impact the security and energy-efficiency of your home. A professional window fitter will ensure your window is safely fitted and secure.

10. Any jobs you're not confident about

Home renovations are not always straightforward, and DIY disasters could cost you thousands of pounds to fix. Don’t put pressure on yourself to DIY if you’re not confident you have the knowledge or the tools to do it right. You could just end up causing yourself more hassle – and expense – in the long run.


Boost your home improvement budget

Home improvements can be expensive, whether you’re doing the job yourself or you’re looking for a contractor. If you want to create your dream home sooner, consider a personal loan to get access to the money you need. Borrow up to £35,000 and spread the cost by making fixed-rate monthly instalments over 2 to 7 years.

With Novuna Personal Finance, you could get the money you need to complete your renovations at low rates from just 6.9% APR Representative (£7,500-£25,000).
