Quiz: Who should buy materials — the contractor or the homeowner?
Who buys materials for a construction project: the contractor or the homeowner? The pros and cons of both options — from quality control to liability for installation defects.
Weekend quiz: bathroom renovation, contractor quote of £2,400 for labor. Who should buy the tiles, bathtub, and fixtures — you or the contractor? Write down your answer.
Answer: It depends on what you value more
Option: The homeowner buys
- Pros: full quality control, you buy exactly what you chose, zero contractor markup.
- Cons: responsibility for material defects falls on you — a bathtub damaged during installation is your cost and your logistical headache.
Option: The contractor buys
- Pros: wholesale prices (often lower than retail), the contractor knows the products they are skilled at installing — and defects in installation or materials become their problem.
- Cons: they add a markup (£100–£350) and may suggest only "what we always use."
Recommendation
- Critical materials (windows, roof, insulation): contractor — responsibility and warranty in one pair of hands.
- Cosmetic materials (paint, fixtures): homeowner — full control over selection.
