Money you spend before being paid£2,280.00
Materials £2,100.00 + early subcontractors £0.00 + hire £180.00.
That as a share of the job35.6%
Early outlay ÷ job value. This is the honest justification you give the customer for the deposit.
Suggested deposit40.6%
Cost share 35.6% plus a 5-point allowance for a first-time domestic customer.
Deposit amount£2,600.00
40.6% of £6,400.00.
Cost still funded by you£0.00
Early outlay less the deposit. You carry this for roughly 0 days beyond your supplier terms.

Deposits should be proportionate to costs you genuinely incur early. Taking money far in advance of any work can undermine trust and, for consumer contracts, cancellation rights still apply.

How this is worked out

The deposit is justified by costs you actually incur early, plus a small allowance for customer risk.
Suggestions are capped at 50% because higher domestic deposits are usually resisted and can undermine trust.
Consumer cancellation rights and any contractual terms still apply regardless of the deposit taken.

Results are planning aids based on figures you enter. They are not financial, tax or legal advice, and no price is guaranteed to be accepted.
