DIY vs Hiring a Professional: When to Call in the Experts
With home improvement costs rising, more homeowners are considering DIY. But some jobs are genuinely dangerous or require certified professionals. Here is how to decide.
Jobs You Can Safely DIY
- Painting and decorating — Internal walls, ceilings, woodwork
- Flatpack furniture assembly — Wardrobes, shelving, desks
- Garden maintenance — Mowing, weeding, planting, basic fencing repairs
- Wallpapering — With patience and the right tools
- Replacing door handles, hinges, light fittings (like-for-like)
- Filling and sanding — Cracks, holes, prep work before painting
- Laying laminate or vinyl click flooring — On a flat, prepared subfloor
Jobs You Must Hire a Professional For
- Gas work — Must be done by a Gas Safe registered engineer (legal requirement)
- Electrical work — New circuits, fuse boards, bathroom/kitchen electrics (Part P)
- Structural changes — Removing walls, adding steels, underpinning
- Roofing — Height work requires safety equipment and expertise
- Plumbing — While minor fixes are DIY-able, waste pipe alterations and boiler work need a professional
- Asbestos removal — Must be handled by licensed professionals
- Damp proofing — Incorrect treatment can make problems worse
The Hidden Cost of DIY Gone Wrong
A botched DIY job often costs more to fix than hiring a professional in the first place. Common examples:
- Bad tiling: £400–£800 to strip and re-tile
- Incorrect plumbing: £200–£500 for water damage repairs
- Electrical faults: £300–£1,000+ for emergency rewiring
- Structural mistakes: Potentially £5,000–£20,000+
The golden rule: if a mistake could cause injury, water damage or structural failure, hire a professional.
Frequently Asked Questions
Is it worth doing my own painting?
For most homeowners, yes. Internal painting is one of the easiest DIY jobs and can save £200–£500 per room compared to hiring a decorator. Invest in good-quality brushes, rollers and masking tape for the best results.
Can I install my own kitchen?
You can install kitchen units yourself if you are handy, but the plumbing, gas and electrical connections must be done by certified professionals. Many homeowners fit the units and hire specialists for the connections to save money.
