Who's liable if a kitchen job goes wrong: contracts, insurance and deposits

This is general information to help you ask the right questions before a kitchen job starts, not legal advice for a specific dispute. If you’re dealing with an active problem, a solicitor, Citizens Advice, or Trading Standards can give guidance specific to your situation.

Most kitchen fitting jobs go fine. But knowing where responsibility sits before you sign anything means you’re not working it out for the first time in the middle of a dispute.

Who’s generally responsible for what

The tradesperson you contracted with is generally liable for the quality and safety of the work they carry out, and for damage they cause to your property while doing it. This is exactly what public liability insurance is designed to cover, which is why checking a fitter carries current, valid cover is worth doing before work starts, not after something goes wrong.

Subcontracted trades don’t automatically shift liability away from the business you hired. In most cases, the company you contracted with remains responsible to you for the finished job, even if they brought in a plumber or electrician to do part of it. Confirm this explicitly in your written agreement rather than assuming it, since terms can vary.

Manufacturer defects in units, appliances or worktop materials are typically covered separately under the manufacturer’s or supplier’s own warranty, distinct from the fitter’s liability for installation quality.

Situation	Generally covered by
Fitter damages your property during work	Fitter’s public liability insurance
Poor quality installation (misaligned units, leaks from bad plumbing)	The contracted business, even if a trade was subcontracted
A faulty appliance or manufacturing defect in a unit	Manufacturer or supplier warranty
Delay causing you additional costs	Depends on what the contract specifies

Structural work adds another layer of risk here: removing a wall without a properly certified structural beam installation is one of the more expensive things to get wrong, and it’s exactly the kind of job where clear paperwork protects you later.

What a solid contract should cover

• An itemised scope of work: exactly what’s included, units, worktop, labour by trade, and what isn’t
• A payment schedule tied to milestones, deposit to secure the start date, a stage payment as work progresses, and a final payment once snagging is complete, rather than most of the cost upfront
• A written timeline, even an approximate one, so delays are measurable against something
• What happens if the scope changes mid-job, how variations are priced and agreed

Deposits: what’s reasonable and what’s a warning sign

A deposit to secure materials, particularly for bespoke or made-to-order cabinetry, and to hold your slot in the fitter’s schedule is standard practice across the trade. What’s worth more caution is a request for most or all of the payment before any meaningful work has started, since that leaves you with very little room to push back if the job is delayed, paused, or not finished to standard. A staged schedule, a smaller deposit up front, a payment when units and worktop arrive, a final payment once snagging is signed off, keeps risk shared more evenly between you and the fitter, rather than sitting almost entirely on your side of the ledger from day one.

If a fitter refuses to work on anything other than a large upfront payment, ask why directly. Sometimes there’s a reasonable answer, a small independent workshop covering the cost of bespoke materials ordered specifically for your job, for instance. Other times it’s simply a business practice worth walking away from, particularly if nothing else about the quote or paperwork inspires confidence either.

Checking insurance before work starts

Public liability insurance is the policy that matters most for a kitchen job, since it covers damage the tradesperson causes to your property while working. It’s reasonable to ask to see evidence of current cover before signing anything, a legitimate business should have no issue producing it. If a fitter is reluctant to show proof of insurance, treat that the same way you’d treat any other missing piece of paperwork: as a reason to look elsewhere rather than assume it will be fine.

If something does go wrong

Document problems as they happen, photos, dated notes, written correspondence, since this matters if a dispute needs resolving formally later. Raise issues with the fitter directly and in writing first, most disputes get resolved at this stage without anything more formal being needed, and a fitter with a genuine interest in their reputation will usually want to put things right rather than let a complaint escalate.

If that doesn’t resolve things, options generally include mediation, a claim through a trade association’s dispute scheme if the fitter belongs to one, or, for larger amounts, the small claims court. Keep in mind that pursuing any of these routes is easier with a clear paper trail: the original written contract, the payment schedule, and dated records of what was agreed and when.

Checking a fitter’s insurance, trading history, and how they’ve handled past issues, visible in detailed customer reviews, not just star ratings, before you hire is the most effective way to avoid needing any of this in the first place.
