Questions to ask your installer
Take these to your next conversation with your fitter
- 1Are you comfortable installing products I supply?
- 2What happens if something I've supplied is faulty?
- 3Do you need to inspect products before installation day?
- 4Will you provide any warranty on your labour if I supply products?
- 5What products would you recommend I leave to you to source?
- 6Are there items where quality really matters that I shouldn't cut corners on?
💡 Tip: A good installer will welcome these questions. If they dismiss them, that's a red flag.
💡Myth vs Reality
Common Myth
"Installers only want to supply products to mark them up"
The Reality
Many installers prefer trade products because they know the quality and can get quick replacements if something is faulty.
Common Myth
"If the installer fits it, they're responsible if it fails"
The Reality
Responsibility depends on what was agreed. Faulty products are the supplier's problem, but proving fault can be difficult.
Common Myth
"You'll always save money by buying products yourself"
The Reality
Trade discounts can be significant. And cheap products often cost more in callbacks, replacements, and frustration.
What to look for
- •Clear written agreement on who handles returns and replacements
- •Understanding that some installers prefer sourcing products themselves
- •Recognition that product quality varies enormously at budget price points
- •Knowledge that some warranties require professional installation
Common mistakes
- •Assuming blame automatically falls on the installer if products fail
- •Not checking product specifications match installer requirements
- •Buying products without consulting the installer first
- •Not inspecting products before installation day
- •Assuming online bargains are equivalent quality to trade supplies
Quality considerations
- •Many installers dislike client-supplied suites because if a cheap product fails, the blame often falls on the fitter even when the issue is product quality
- •Trade suppliers often provide better aftercare and replacement processes than retail websites
- •Some products (like concealed valves) need installer sign-off on compatibility
- •A good working relationship is worth more than saving £100 on a tap
