Who Pays for Materials: You or the Provider?
How materials are usually handled on local service jobs, the pros and cons of supplying them yourself, and how to agree it clearly in writing.
Materials are one of the most common sources of friction on local jobs. Someone assumes the provider will bring everything. The provider assumes the customer has bought the tiles. The result is either a delay on the day or an unexpected line on the invoice. There is no single correct answer. What matters is that you both decide in advance.
The three common arrangements
The provider supplies and charges for materials
The provider buys what is needed and includes the cost in the price, or lists it separately. This is convenient, since they know what is required and often have trade access to suppliers.
Pros: Less effort for you, correct items, fewer delays. Cons: The provider may add a margin, which is usually reasonable for their time and risk, but should be transparent. You have less control over brand and cost.
You supply the materials
You buy the items and the provider fits them.
Pros: Control over choice and price. You may find offers. Cons: If you buy the wrong thing or too little, work stops. If the item is faulty, you and the provider need to work out whose responsibility it is. Some providers will not guarantee work with customer-supplied materials, or may charge more for the risk.
A mixture
You pick and buy the visible, personal items such as tiles, taps or paint colours, while the provider supplies the unseen consumables such as adhesive, fixings and sealant. This is probably the most common arrangement.
What to agree in writing
Before the work starts, put these points in a message or offer:
- A list of materials needed. Be specific, including quantities and specification if you can.
- Who buys what.
- How much is allowed for materials, if the provider is buying them, and whether you will see receipts.
- Any mark-up or handling charge.
- Who collects or arranges delivery, and who will be at home to receive it.
- What happens to leftovers. Who keeps spare tiles or paint?
- What happens if you need more. Ask them to tell you before buying extra.
See agreeing scope in writing for how to keep this tidy.
Receipts and transparency
If you reimburse materials, ask for receipts or a clear itemised list. This is not an accusation. It is a normal part of billing and helps both sides remember what was bought. If the provider buys on a trade account and passes on the cost, the receipt may be an invoice from the supplier or a summary. Either is acceptable if it is clear.
If materials are included in a fixed price, you generally do not need receipts, but you should still know what is being used, particularly if quality is a priority.
Quality and specification
Two quotes for "a new shower" may assume entirely different materials. If quality matters, specify:
- Brand or range, or at least a quality level
- Size, finish and colour
- Anything you have already chosen
Otherwise, the quote may reflect basic options, and an upgrade costs extra. This is a frequent cause of "hidden" costs. See hidden costs in home service quotes.
What if materials are wrong or defective?
- If the provider bought them, they should generally put it right. Their work and their selection are their responsibility.
- If you bought them, the provider can reasonably say they are not responsible for the item, though they should still fit it with proper care. Agree beforehand what happens if a problem is found, for example that they will tell you immediately and you will decide how to proceed.
- If an item is faulty, keep the receipt and packaging, and contact the retailer under your rights as a buyer of goods.

Delivery and storage
Large deliveries can fill hallways. Agree where items will be stored, who will be home and who is responsible for damage in transit. Checking deliveries on arrival for damage or shortages avoids arguments later.
When the price changes because of materials
Prices of materials fluctuate. For longer projects, ask whether the quote is fixed regardless of changes, or whether the materials element could move, and under what conditions.
Frequently asked questions
Is it normal for a provider to add a mark-up on materials?
Many do, to cover time sourcing and carrying risk. It should be disclosed and reasonable. Ask if you are unsure.
Will a provider fit materials I bought myself?
Often yes, but some prefer not to. Ask first and agree what happens if the items turn out to be unsuitable.
Should I ask for receipts?
Yes, if you are reimbursing costs. It is a normal request and keeps things transparent.
