Calculate residual funding when an apprentice changes employer mid-programme
When an apprentice changes employer during their apprenticeship, the funding arrangements must be recalculated. The new employer takes on the apprenticeship at a residual Total Negotiated Price (TNP) that reflects the remaining training to be delivered.
Key Points:
30-Day Rule:
If the gap between leaving the first employer and starting with the new employer is 30 days or less, the apprenticeship can continue as a change of employer. If the gap exceeds 30 days, you must record it as a withdrawal and restart.
The original TNP (TNP1 + TNP2) is split into 80% monthly funding and 20% completion payment
Based on the number of months with the first employer, calculate how much of the 80% monthly funding has been paid
Remaining funding = (Unpaid monthly funding) + (20% completion payment still available)
The residual TNP (TNP3 + TNP4) must not exceed the remaining funding available
Important:
The residual price (TNP3 + TNP4) should be agreed between the provider and the new employer. It must reflect the remaining training to be delivered and must not exceed the available funding.
Automatically calculates the remaining available funding based on months completed with the first employer
Checks if the gap between employers meets the continuation criteria (≤30 days)
Provides the correct stop and start months to use in the Apprenticeship Service to avoid DLOCK_10 errors
Automatically calculates the residual training price (TNP3) based on remaining funding and EPA cost

Provide the programme timeline:
The calculator will automatically check if the gap between employers is 30 days or less. If it exceeds 30 days, you must record as a withdrawal and restart, not a continuation.
The tool provides the exact months that both employers should use in their Apprenticeship Service accounts to prevent DLOCK_10 data lock errors.
The calculator automatically calculates:
Record TNP3 and TNP4 in the Apprenticeship Financial Record entity alongside the new employment status record. Ensure both employers use the recommended DAS months.
The calculator provides a clear interface to enter employer change details, automatically validate the 30-day gap rule, calculate residual funding, and get DAS month recommendations to prevent DLOCK_10 errors.

Key Rule: An employer pays for a month if they are the employer on the last day of that month.
Example:
DLOCK_10 is a common data lock error that occurs when the months recorded by the two employers don't match. The calculator helps prevent this by:
✓ Providing exact DAS month recommendations
Both employers must use the same month in their Apprenticeship Service accounts for the stop/start
✓ Warning when dates span different months
If the learner left in one month but started the new employment in a different month, the calculator warns you to ensure both employers use the correct month
✓ Following DfE business rules
The stop/start month should be the month AFTER the learner left employment (when gap ≤30 days)
Use the Change of Employer Calculator to accurately calculate residual funding and get DAS month recommendations.
