Fulfilment policy

How we handle ordering, payment, delivery and completion, from your first enquiry to final handover.

This Fulfilment Policy sets out how Carter Langfold Limited ("we", "us", "our") manages the ordering, payment, delivery and completion of all building, construction and renovation works for our clients ("you", "your"). It applies to every project commissioned with us, from initial enquiry through to final handover.

In short: we typically ask for a deposit to secure your project and schedule the work. The remaining balance is payable on completion of the works to your satisfaction. This approach protects both parties and helps us deliver your project to a high standard.

1. Payment structure

Our standard payment model is built around two key stages, a deposit upon agreement and a final balance upon completion. This structure is designed to give you confidence that work will be completed before full payment is made, while allowing us to secure materials, schedule labour and allocate resources to your project.

StageWhen dueWhat it covers
DepositOn acceptance of the quotation and signing of the works agreementSecures your project date, initial material procurement, site surveys, and the scheduling of trades and labour
BalanceOn completion of all works, following final inspection and your written approvalFinal labour costs, all remaining materials, finishing work, site clearance and handover documentation

1.1 Deposit details

The standard deposit is 25% of the total agreed project cost, unless otherwise stated in your quotation. The deposit must be paid before any works commence or materials are ordered. Once your deposit is received, your project is formally scheduled and our team begins procurement and planning. Deposits may be paid by bank transfer, debit card or cheque. We do not accept cash for deposits.

1.2 Balance details

The remaining balance is due on completion of all works and after you have carried out a final inspection. You will receive a completion invoice detailing the balance owed. Payment of the balance is due within 7 days of the completion invoice being issued. Balance payments may be made by bank transfer, debit card or cheque.

1.3 Larger projects and stage payments

For larger or longer projects (typically those exceeding four weeks or £30,000 in value), we may agree a stage payment schedule in addition to the deposit and final balance. Where this applies, it is set out clearly in your quotation and works agreement, with agreed milestones for each interim payment. Stage payments are always agreed in writing before works commence.

2. Fulfilment process, start to finish

We follow a structured process so that every project runs smoothly from the first conversation to the final handover.

1. Initial consultation and quotation. We visit your property, or arrange a virtual consultation, assess the scope of work and provide a fixed-price quotation within 5 to 7 working days. The quotation is valid for 30 days from the date it is issued.

2. Acceptance and deposit. Once you accept the quotation and sign the works agreement, the deposit is due. On receipt, we confirm your project dates, begin ordering materials and schedule our trades team.

3. Pre-commencement planning. Where required, we handle planning applications and building regulations submissions. We confirm a start date with you and provide a realistic project timeline. Typical lead time from deposit to commencement is 2 to 6 weeks, depending on the scope and any approvals needed.

4. Works commence. Our team arrives on the agreed start date. We manage all trades, coordinate deliveries and keep you informed of progress throughout. Site work follows all health and safety regulations, and we keep a clean, organised site.

5. Final inspection and snagging. Once works are substantially complete, we walk you through the finished project. Any snagging items are documented and addressed promptly, typically within 5 working days.

6. Completion, handover and balance payment. Once all snagging is resolved and you are satisfied with the work, we issue the completion invoice. The balance is payable within 7 days. You receive all relevant warranties, guarantees and handover documentation.

3. Expected timelines

We aim to deliver projects on time and within budget. Below are indicative timelines for common project types. Actual durations are confirmed in your quotation.

  • Loft conversions. 4 to 6 weeks from commencement.
  • Single-storey extensions. 4 to 8 weeks from commencement.
  • Orangeries and conservatories. 2 to 4 weeks from commencement.
  • Roofing works. 1 to 3 weeks, depending on scope.
  • Spray foam removal. 2 to 5 days.
  • Driveways and landscaping. 1 to 3 weeks, depending on scope.
  • Garage conversions. 2 to 4 weeks from commencement.

Timeline estimates exclude any planning permission or building regulations approval periods, which are subject to local authority processing times, typically 8 to 13 weeks for a standard planning application.

4. Cancellation and refunds

4.1 Cancellation by you

Before works commence. If you cancel before the start date, the deposit is non-refundable, as it covers committed costs including ordered materials, scheduled labour and administrative work already carried out.

After works commence. If you cancel after works have started, you are liable for all costs incurred up to the point of cancellation, including materials, labour and subcontractor costs. Any remaining deposit may be applied toward these costs.

Cooling-off period. If you cancel within 14 days of signing the agreement and works have not yet commenced, you are entitled to a full refund of your deposit, less any costs already incurred for materials, surveys or planning ordered on your behalf.

4.2 Cancellation by us

If we are unable to fulfil your project for any reason, including unforeseen circumstances beyond our control, we will notify you in writing as soon as practicable. In such cases, your deposit will be refunded in full within 14 days of cancellation.

4.3 Delays

While every effort is made to keep to timelines, some delays may occur due to weather, material supply issues or circumstances beyond our control. We will communicate any delays promptly and adjust the schedule accordingly. Delays caused by factors outside our control do not constitute a breach of this policy.

5. Variations and additional works

If you request additional or different work from what was originally quoted, or if unforeseen issues arise during construction, for example hidden structural problems, damp or asbestos, we will:

  • Discuss the variation with you before any additional work is carried out.
  • Provide a written variation quote detailing the additional cost and any impact on the timeline.
  • Proceed only once you have approved the variation in writing.
  • Add the agreed variation cost to your final balance invoice, or request payment at the time if material procurement is required.

6. Guarantees and warranties

All works completed by Carter Langfold are backed by the following:

  • 12-month workmanship warranty covering defects arising from our work.
  • 10-year structural warranty where applicable, for example extensions, loft conversions and structural works.
  • Manufacturer warranties on all materials and fixtures, passed directly to you on completion.
  • Insurance-backed guarantees available through our trade body memberships, backing our written guarantees for as long as 10 years.

Warranties do not cover normal wear and tear, misuse, or issues caused by third-party works or modifications carried out after our completion without our involvement.

7. Complaints and dispute resolution
