DIY vs. Calling a Professional
As a first-time homeowner, one of the most common questions you’ll face is: “Can I fix this myself, or do I need to call someone?”
Get it wrong and it can cost you — either by paying for a tradesperson you didn’t need, or by turning a small problem into an expensive disaster. This guide will help you make the right call every time.
The Golden Rule
Ask yourself these three questions before picking up a tool:
- Is it safe? — Anything involving electricity, gas, or structural work can be dangerous if done wrong.
- Do I have the skills? — Be honest. Watching a YouTube tutorial isn’t the same as having experience.
- What happens if I get it wrong? — A botched paint job is fixable. A botched pipe repair can flood your home.
If you can’t confidently answer all three, call a professional.
Jobs You Can Almost Always DIY
These tasks are low-risk, easy to learn, and perfectly safe for beginners:
- Painting walls and ceilings — Take your time, prep properly and you’ll get great results.
- Replacing a lightbulb or light fitting — As long as you turn off the power at the fuse box first.
- Unclogging a drain — A plunger or drain snake handles most blockages easily.
- Filling small holes in walls — Polyfilla and a bit of sandpaper is all you need.
- Assembling flat-pack furniture — Time-consuming but straightforward.
- Replacing a toilet seat — Two bolts. That’s it.
- Touching up grout in the bathroom — Easy with a grout pen or tube of grout.
- Bleeding a radiator — Takes 5 minutes and can make a big difference to your heating.
Jobs to Think Carefully About
These are doable for a confident beginner, but worth researching thoroughly first:
- Laying laminate or vinyl flooring — Not too difficult, but mistakes are hard to undo.
- Replacing a tap or showerhead — Fine if you know how to turn off the water supply.
- Tiling a small area — Requires patience and the right tools.
- Hanging shelves or TV brackets — Easy if you can find the studs or use the right wall plugs.
- Basic garden work — Planting, pruning, and lawn care are great DIY projects.
Jobs You Should Always Call a Professional For
Don’t risk these — the cost of getting them wrong is far higher than the tradesperson’s bill:
- Any gas work — Boiler repairs, gas appliance installation, or anything involving gas pipes. In most countries this is also illegal to do yourself without qualifications.
- Major electrical work — Rewiring, adding new circuits, or anything in the fuse box. Always hire a qualified electrician.
- Structural changes — Removing walls (especially load-bearing ones), loft conversions, or extensions.
- Roof repairs — Besides the safety risk of working at height, a poorly fixed roof can cause serious water damage.
- Subsidence or foundation issues — If you notice cracks in your walls getting bigger, call a structural engineer.
- Asbestos removal — If your home was built before the 1990s and you’re doing renovation work, always get it tested first.

How to Find a Good Tradesperson
When you do need a professional, here’s how to find someone reliable:
- Ask neighbours or friends — Word of mouth is still the best recommendation.
- Check review sites — Look for tradespeople with lots of recent reviews.
- Always get 3 quotes — Don’t just go with the first person you find.
- Check their qualifications — Gas engineers should be Gas Safe registered. Electricians should be NICEIC or NAPIT approved.
- Never pay the full amount upfront — A small deposit is fine, but pay the rest when the job is done.
Final Thoughts
There’s no shame in calling a professional — in fact, knowing when to do so is one of the smartest skills a homeowner can have. Save your DIY energy for the jobs that are safe and satisfying, and leave the risky stuff to the experts.
