Customer supplied bathroom materials

A customer finds a cheap shower valve online, buys tiles in a sale, orders a vanity unit with no fitting instructions, then expects the bathroom fitter to make it all work. That can be fine, but only if the rules are clear before the job starts.

Decide your policy before the quote

Some fitters prefer to supply everything because they know the products, the merchant, the lead times and the warranty route. Others are happy to fit customer-supplied items but charge only for labour and make the customer's responsibility clear.

Neither approach is automatically right. The problem is having no policy until something goes wrong.

What can go wrong with customer-supplied items?

• Items arrive late and push the job back.
• Parts are missing, damaged or the wrong size.
• Tiles vary by batch or there are not enough extras for cuts and breakages.
• Cheap fittings take longer to install or do not suit the existing setup.
• Warranty responsibility becomes unclear.
• The customer expects you to deal with the supplier even though you did not sell the item.

Put responsibility in writing

If the customer supplies products, your quote and terms should say who is responsible for checking delivery, condition, suitability, quantities, instructions and warranty claims.

Under UK consumer law, services should be carried out with reasonable care and skill. That does not mean a fitter should silently take responsibility for a faulty product they did not supply. But it does mean your workmanship still needs to be competent and your wording should not try to remove rights unfairly.

Check products before booking the install

Ask for product links or photos before you quote. For tiles, ask about size, quantity, trim, grout, adhesive and waste allowance. For brassware and showers, check pressure requirements, valve type and whether the item suits the planned layout.

This is especially important for online purchases where the customer may have chosen by look and price rather than suitability.

Charge for delays and extra work fairly

If a job stops because a customer-supplied part is missing, that can cost you time. Your terms should explain what happens if materials are not ready or if unsuitable products create extra labour.

Keep it fair and clear. The aim is not to punish the customer. It is to stop your diary and profit being damaged by things outside your control.

How YourQuoteApp helps

YourQuoteApp can collect product choices, photos, files and notes before the quote. That gives you a better chance of spotting customer-supplied material issues before you are standing in a stripped-out bathroom.

It also helps you send a more professional quote PDF, so scope, exclusions and next steps are clearer from the start.
