Map a letter of response into issues and evidence

Tarnwell Interiors Ltd v Pellow & Vine Restaurants LtdConstruction payment disputeFictional

The situation

We act for a fit-out contractor owed £48,600 on its fourth interim application for a restaurant kitchen and dining room. Our letter of claim went out on 7 August 2026. The employer’s solicitors replied on 2 October 2026, four weeks after the period we gave them, alleging defects and delay and setting both off against the sum claimed. The supervising solicitor wants an issues map before Thursday’s client meeting.

Why it matters

A letter of response sets the agenda for everything that follows. If ‘not admitted’ is read as ‘denied’, or a point the other side ignored goes unnoticed, the client meeting and the next letter start from the wrong place.

D1Letter of claim (extract)Our firm to Ashdown Reeve LLP · 7 August 2026

We act for Tarnwell Interiors Ltd (“Tarnwell”), which carried out the fit-out of your client’s restaurant premises under a contract dated 2 March 2026 (the “Contract”). The contract sum was £186,000 plus VAT.

Tarnwell submitted Interim Application 4 on 30 June 2026 in the sum of £40,500 plus VAT (£48,600).

Under clause 4 of the Contract the due date was 7 July 2026 and the final date for payment was 28 July 2026. Tarnwell received no payment notice and no pay less notice. The sum of £48,600 is due and remains unpaid.

Tarnwell also claims statutory interest and compensation under the Late Payment of Commercial Debts (Interest) Act 1998.

Completion was delayed by your client’s instruction of 8 April 2026 to change the specification of the kitchen extraction canopy. Tarnwell notified the delay and asked for an extension of time on 9 April 2026. Practical completion was achieved on 26 June 2026.

Please respond within 28 days of the date of this letter.

D2Letter of response (extract)Ashdown Reeve LLP to our firm · 2 October 2026

We act for Pellow & Vine Restaurants Ltd (“our client”). Our client acknowledges receipt of Interim Application 4 on 30 June 2026.

The sum claimed is not admitted. Interim Application 4 did not set out the basis on which the sum claimed was calculated, as clause 4.1 requires, and was not a valid application.

The kitchen extraction ductwork installed by your client is defective. Our client’s mechanical engineer identified grease leakage at two duct joints on 18 August 2026, and a copy of his report is enclosed. Our client has obtained a quotation of £18,400 plus VAT from Quarrendon Mechanical Ltd for the remedial works.

The works were completed six weeks after the Completion Date of 15 May 2026. Our client is entitled to liquidated damages at £750 per week under clause 6.2, a total of £4,500.

Our client will set off the remedial costs (£22,080 including VAT) and the liquidated damages (£4,500) against any sum found to be due to your client.

Your client’s claim to interest is denied.

Our client reserves its position on its consequential losses, including the closure of its kitchen while the remedial works are carried out, presently estimated at £9,000.

D4Client emailTom Tarnwell, director, to our firm · 6 October 2026 · Attachments: none

Their letter is rubbish. App 4 went in with our usual valuation sheet, same format as Apps 1 to 3, which they paid without a word. I’ve attached it.

We never got a payment notice or a pay less notice. Nothing at all until their solicitor’s letter.

Nobody told us about any leak until this letter. We’d have fixed it in a day. Their engineer never contacted us.

The canopy change on 8 April cost us five weeks. I emailed Priya, their operations manager, on 9 April asking for more time, and she replied ‘noted, crack on’.

Practical completion was 26 June. We’ve got the handover sheet signed by their general manager.

Why this prompt works

A closed set of status labels

Five labels force a decision on every point. NOT ADDRESSED sends the tool looking for what the other side left out, which is where the payment-notice point sits.

Legal flags without legal conclusions

Step 5 lets the tool raise the statutory payment point without inventing authority for it or deciding it.

Paragraph citations

Every row can be checked against the letters in seconds.

A completeness check

The self-check stops a common failure: the last paragraphs of a long letter quietly dropping out of the analysis.

Working

Clause 4 timetable: received 30 June → due date 7 July → final date for payment 28 July 2026. Last day for a pay less notice: 23 July 2026 [D3 cl 4.2, 4.4].

Delay: 15 May to 26 June 2026 = 42 days = 6 weeks. 6 × £750 = £4,500 [D2 §4].

The client attributes five weeks to the variation [D4]. One week, up to £750 at the clause 6.2 rate, is not explained by the sources.

Set-off: £18,400 + 20% VAT (£3,680) = £22,080 [D2 §3, §5].

Response time: D1 asked for a reply within 28 days, by 4 September 2026. D2 is dated 2 October 2026, 28 days after that.

B. Documents referred to but not supplied

Valuation sheet for App 4. The client says it is attached, but no attachment came with the email [D4].
Interim Applications 1–3 and the payment records [D4]
Engineer’s report of 18 August 2026, described as enclosed [D2 §3]
Quarrendon Mechanical quotation [D2 §3]
Client’s email of 9 April 2026 and the reply [D4]
Handover sheet signed by the general manager [D4]
Variation instruction of 8 April 2026 [D1 §5]

C. Points to verify

Payment notices. D2 does not mention a payment notice or a pay less notice. If none was given, consider the effect of clause 4.4 [D3] and section 111 of the Housing Grants, Construction and Regeneration Act 1996 on the employer’s ability to withhold the sum applied for. Confirm first that the Contract is a construction contract within the Act.
Validity of App 4. Whether it stated the basis of calculation (cl 4.1) depends on the valuation sheet, which we have not seen. Consider the relevance of Apps 1–3 being paid in the same format.
Remedial costs. Clause 7.3 requires written notice of a defect and 14 days for the contractor to begin making good. No notice appears in the papers.
Liquidated damages. The effect of the 8 April variation and the 9 April request on the Completion Date under clause 6.1.
VAT. The remedial cost is claimed including VAT. Consider whether VAT is properly part of the claim if the employer is VAT-registered.

D. Questions for the client

Application: Please send App 4 exactly as submitted, with the valuation sheet and the covering email. When were Apps 1–3 paid?
Notices: Did anyone at Tarnwell receive any letter or email from Pellow & Vine about App 4 between 7 and 23 July 2026? Please check site staff inboxes too.
Defects: Have you ever had written notice of a defect? Do you hold commissioning or test records for the extraction system?
Delay: Please send the 9 April email and Priya’s reply. Was an extension ever granted in writing? What caused the sixth week?
Completion: Please send the signed handover sheet.

Assumptions. £48,600 is treated as including VAT, as D1 paragraph 2 states. The date of receipt of App 4 is taken from D2 paragraph 1.

Before you rely on it

Read D2 yourself and confirm every status. Tools blur ‘not admitted’ and ‘denied’ more than any other distinction.
Recalculate the clause 4 timetable from the actual date of receipt of App 4, not the date on the application.
Check the payment-notice point against the statute and current authority before anyone relies on it. The tool was told not to cite cases; don’t let a later draft add any without checking each one.
Confirm which pre-action protocol applies. A construction dispute will usually fall under the Pre-Action Protocol for Construction and Engineering Disputes, which has its own response timetable and a pre-action meeting.
Use a tool your firm has approved for client documents. These letters identify the client and its commercial position.

Where tools go wrong

Treating ‘the sum claimed is not admitted’ as a denial.
Reporting only what D2 says and missing what it leaves out: the absence of any notice and the extension of time request.
Accepting six weeks of delay without noticing that the client’s own account covers five.

Adapt it

After issue, use the same structure on a defence with the CPR 16.5 categories: admitted, denied (with reasons and any different version of events) or required to be proved.
Add your firm’s construction know-how note as a further source if you want the tool to apply it.
