Commercial Debt Recovery for Mechanical Contractors
Recover unpaid mechanical contractor invoices, HVAC contract payments, installation fees and maintenance charges with an approach built around your subcontract, applications, variations and site records.
Mechanical debts often depend on applications, sign-off and variations
Payment may depend on interim applications, valuations, commissioning, test results, completion stages or retention provisions. Debtors may also raise snagging, performance, delay or variation arguments.
We first confirm the subcontract or order, the work completed, the payment trigger and the evidence supporting the balance. That helps us separate a genuine project dispute from ordinary non-payment.
Common debts we can assess
We review the documents behind the balance before deciding how the debt should be pursued.
Unpaid mechanical contractor invoices
Invoices for mechanical labour, materials, installation or project services that remain unpaid.
HVAC contract payments
Stage or completion payments due for heating, cooling or ventilation work.
Mechanical installation fees
Outstanding balances for installation, replacement or upgrade projects.
Maintenance contract invoices
Recurring service, planned maintenance or reactive call-out charges.
Retention money
Retention sums that should have been released after completion or the defects period.
Variation and extra-work charges
Additional mechanical work supported by instructions, emails or site acceptance.
Testing and commissioning fees
Unpaid charges for balancing, testing, commissioning or certification.
Snagging-related withholding
Payment withheld because of alleged defects, outstanding items or incomplete remedial work.
Final-account balances
Residual balances after project completion and account reconciliation.
What we look at before taking action
A clear evidence pack helps us understand the debt quickly and challenge common payment excuses.
A clear five-step recovery process
We keep the process focused: identify the debt, test the dispute, contact the debtor and escalate only where justified.
Confirm the debtor
Check the correct contractor, project company and accounts-payable contact.
Confirm what is due
Review the subcontract, applications, invoices and payment trigger.
Check the dispute
Assess snagging, performance, variations, deductions and retention.
Pursue payment
Use focused telephone and written recovery action.
Escalate carefully
Consider formal demand, court or enforcement only where appropriate.
Choose the right recovery route
The best route depends on the subcontract, site records, dispute status, debtor solvency and value of the debt.

Some contractors rely on broad snagging or performance arguments after payment falls due. Others raise a specific defect, commissioning, variation or valuation issue.
We identify what is actually disputed, compare it with the site and payment records and determine whether the whole balance—or at least part of it—remains due.
Can interest and compensation be added?
Depending on the contract and circumstances, you may be entitled to contractual interest or statutory interest and fixed compensation.
We check the payment terms and due dates before including additional sums in a demand.
