How Do I Respond to a Snagging List? Acknowledging, Scheduling & Completing Defects

Summary

A snagging list is a normal part of any significant building or renovation project. The customer has noticed items they believe are defective, incomplete, or not finished to the agreed standard. How you respond shapes not only the outcome of this job but your reputation for future referrals. A prompt, professional response that takes the snagging list seriously — even if you disagree with some items — is always the right approach.

The legal position is clear: the Consumer Rights Act gives customers the right to ask you to complete or remedy defective work once before they pursue any financial remedy. This is actually a protection for tradespeople: it means customers must give you the chance to put things right. If they go straight to hiring another contractor, they may not be entitled to recover the full cost from you. Managing this process correctly is therefore both commercially and legally important.

The most common mistakes are: dismissing items you think are unreasonable without investigation, failing to acknowledge the list at all, or arriving to complete snagging without confirming what you're attending to — then leaving items the customer expected to be done.

Key Facts

• Consumer Rights Act 2015 — customer must allow you the opportunity to remedy before they can claim price reduction or hire alternative contractor at your cost
• Respond in writing — acknowledge every snagging list in writing; silence is interpreted as indifference or admission
• Inspect before responding to merit — never dismiss items as "not my fault" without physically inspecting them
• Distinguish categories — items in scope (your responsibility), items out of scope (not included), and items of opinion (finish within normal trade tolerances)
• Provide a programme — state when each item will be completed; vague commitments are not reassuring
• Completion sign-off — get written confirmation that snagging items are resolved before final payment is released
• Tolerance guidance — NHBC standards and BS 8000 series provide guidance on acceptable tolerances for plastering, tiling, joinery, and other trades
• Workmanship standards — BS 8000 series covers workmanship standards for many trades; these are the benchmark for what is "reasonable care and skill"
• New-build snagging — NHBC registered builders have a warranty scheme that covers defects; the snagging process feeds into NHBC claim procedures

Detailed Guidance

Receiving the Snagging List

When a snagging list arrives — whether as a formal document, email, or WhatsApp message — treat it professionally regardless of format. Acknowledge receipt immediately:

"Hi [Name], thanks for sending this through — I'll review each item and come back to you by [date] with a plan. I'll aim to attend on [date range] to inspect and complete anything that needs addressing."

This brief message:

• Confirms you've received and read the list
• Shows you're taking it seriously
• Sets a clear next step

Do not start responding to individual items until you have inspected the work in person. Many snagging disputes arise from remote disagreements that resolve themselves on site.

Conducting the Inspection

Visit the site and work through the snagging list methodically. For each item:

1. Photograph the item — time-stamped photo for every item, even those you accept as defects
2. Assess cause — is this your workmanship, a subsequent trade, the customer's own actions, or movement/settlement?
3. Assess scope — is this item within the agreed scope of your contract?
4. Assess standard — does it fall outside BS 8000 or other relevant tolerances?
5. Note your assessment in writing, even briefly

If the customer is present during the inspection, this can be productive — but also difficult if they are already antagonistic. If you expect tension, consider bringing a colleague to witness the visit.

The Snagging Response Letter

After inspecting, respond formally with a categorised response:

Snagging Response — [Customer Name] — [Job Reference] Date: [Date]

Thank you for your snagging list dated [date]. I have inspected all items and set out my response below.

Items I accept as defects to be remedied (at no charge):

• Item 1: [description] — I will [action] on [date]
• Item 3: [description] — I will [action] on [date]

Items I do not consider to be defects within my scope:

• Item 2: [description] — This [was not included in the original scope / is within normal tolerances / was pre-existing, as shown in photos taken on [date]]. I am happy to discuss this further if you disagree.

Items where I need clarification:

• Item 4: [description] — Could you clarify exactly what aspect of this [finish/fitting] you are unhappy with? I will reinspect once I understand your concern.

Proposed programme for remedial works: I will attend on [date] to complete items 1 and 3. This should take approximately [X] hours. Please confirm this date suits you.

If you have any questions, please call me on [number].

Items of Opinion and Tolerances

Some of the most contentious snagging items are about subjective quality — the smoothness of plastered walls, the straightness of tiled lines, the flatness of a floor. Relevant standards provide objective criteria:

• Plastering (BS 8000-10) — maximum deviation of 3mm under a 1.8m straightedge for finished plaster; 5mm under a 1.8m straightedge for rough render
• Tiling (BS 5385-1) — maximum 3mm variation in flatness under a 2m straightedge; maximum 2mm lipping between adjacent tiles
• Joinery (BS 8000-5) — door frames plumb within 2mm in 2m; gaps between door and frame should not exceed 4mm at head and sides

If a disputed item falls within the permitted tolerance, you are not obliged to redo it. However, if a customer is genuinely unhappy and the fix is quick, consider remedying it as a goodwill gesture while making clear it is not a defect.

Completing the Snagging Works

When attending to complete snagging:

• Arrive on time and confirm the full list of items you are there to address
• Complete all agreed items in the visit — partial completion generates more disputes
• Photograph all completed items after remediation
• Before leaving, ask the customer to confirm all agreed items are resolved

If an item cannot be resolved on that visit (e.g. specialist materials are needed), advise the customer immediately and provide a new date. Do not leave without explanation.

Completion and Sign-Off

Once all snagging items are resolved, request written confirmation:

"Hi [Name], can you confirm that all the snagging items from the list dated [date] have been completed to your satisfaction? Once confirmed, the final payment of £[X] falls due on [date]."

This closes the snagging process and removes ambiguity about whether further items remain outstanding before final payment.

Snagging and Final Payment

Do not release the final payment yourself before snagging is resolved. If you have staged payments, the final stage should be held until snagging sign-off. If the customer is withholding payment pending snagging, agree a proportionate holdback: the withheld amount should be proportionate to the value of remedial work outstanding, not the total job value.

Example: If snagging involves repainting one wall (value: £200) and the final payment is £3,000, the customer may reasonably withhold £200–300 pending completion. They cannot justifiably withhold £3,000 for a £200 defect.

Frequently Asked Questions

The customer has added items to the snagging list that weren't in the original scope. Do I have to fix them?

No. Your responsibility under the contract is to complete the agreed scope to a proper standard. If the snagging list includes items that were never part of the agreed work (e.g. a damaged item in another room that pre-dates your involvement), politely but firmly note in your response that these are outside scope. Offer to price them as variations if the customer wants them addressed.

The customer's snagging list is unreasonably long and I believe most items are within normal tolerances. What should I do?

Inspect every item before dismissing any. After inspection, categorise each item objectively using relevant standards. For items clearly within tolerance, provide the relevant standard reference. Offer to have one or two disputed items independently assessed — this demonstrates confidence and good faith. Courts and arbitrators respect tradespeople who take snagging seriously and respond methodically.

I've remedied all the items but the customer keeps adding new ones. How do I close this out?

After each round of snagging, request written sign-off on the items addressed before proceeding. If new items are added after sign-off, treat them as a new snagging round and assess each one. If the customer is adding trivial or vexatious items, note in writing: "I've noted your new concerns. I'd ask that you allow me to close out the agreed items from the [date] list before we address any further items." If this pattern continues, involve a trade association mediator or take legal advice.

My work was fine but a follow-on trade has damaged it. Who is responsible for snagging?

You are responsible for defects in your own work. If the damage is clearly caused by a follow-on trade, document this with photographs and communicate it clearly to the main contractor or customer. The follow-on trade should rectify their damage. If the customer is asking you to remedy it, decline unless you are prepared to do so as a paid variation. Do not agree to fix another contractor's damage without being paid for it.

We're in dispute — the customer has refused to pay and won't allow us to complete the snagging. What now?

Send a formal letter before action stating that you have offered to complete all remedial works, the customer has refused access, and you are now proceeding to recover the outstanding debt. The offer to remedy must be genuine and reasonable — it cannot be conditional on immediate payment. Keep all correspondence. This scenario is typically resolved in small claims court — your record of offering to remedy will be your strongest evidence.
