When planning a new build or renovation, one of the first questions that comes up is whether you should buy your own materials or let the builder supply everything. On paper, it might seem like buying materials yourself will save money, but it’s not always that simple.

Let’s look at both options and what you should consider before deciding.

🧱 When You Buy the Materials Yourself

The Pros

You can shop around for the best deals. Buying directly from hardware stores or wholesalers gives you control over pricing. If you’re willing to compare quotes and wait for specials, you might save a bit.
You know exactly what’s being used. Some clients prefer choosing brands or finishes themselves, especially for visible items like tiles, taps, or paint.
You control the quality. You can make sure that what’s delivered on-site meets your standards and not a cheaper alternative.

The Cons

You take on the risk. If you buy the wrong quantity or something gets damaged, it’s your responsibility, not the builder’s.
Delays are on you. If materials arrive late or the wrong items are delivered, the builder may charge extra for downtime.
No trade discounts. Builders often get materials at reduced rates through supplier accounts. Once you buy retail, those savings are lost.
Warranty confusion. If something fails, for example, a tile batch or a paint finish, it can be tricky to know who’s responsible: the supplier or the builder.

🧰 When the Builder Supplies the Materials

The Pros

It’s simpler and less stressful. The builder orders, coordinates deliveries, and takes responsibility if something goes wrong.
Trade discounts. Builders often get better rates on bulk purchases, and even if they add a small markup, the total cost can still work out lower.
Accountability. If there’s a defect, shortage, or damage, the builder handles it. You don’t have to chase suppliers.
Smoother workflow. Materials arrive when needed, keeping the project moving without unnecessary delays.

The Cons

Less control over brands. Some builders might choose products that are more affordable or that they’re familiar with, not necessarily your first choice.
Hidden markups. A builder might include a margin on materials. That’s fair business practice, but it’s important to know it’s there.
You rely on their honesty. If you don’t have a detailed quote or bill of quantities, it can be hard to verify what materials you’re paying for.

⚖️ The Best of Both Worlds

Many homeowners choose a mixed approach, and it often works best.

Let the builder supply structural materials like bricks, cement, timber, and roofing.
You supply finishes such as tiles, paint, or light fittings that suit your personal taste.

That way, the builder stays responsible for critical materials that affect progress and quality, while you maintain control over the decorative aspects.
