Invoice Finance for Electrical Contractors
Electrical contracting has the same cash flow problem as the wider construction sector — amplified by the cost of copper, switchgear, and specialist materials. You buy £5,000-£20,000 of materials per job, pay your electricians weekly, and wait 45-60 days for the main contractor to pay your application. Construction factoring bridges that gap by advancing 80-90% of each certified application within days.
Why Electrical Contractors Need Specialist Factoring
Standard invoice finance providers sometimes struggle with construction applications for payment. They want clean invoices for delivered goods. In electrical contracting, your "invoices" are applications for payment under JCT or NEC contracts, often with retentions, variations, and contra charges.
Specialist construction factoring providers like Bibby, Close Brothers, and Ultimate Finance understand all of this. They advance against certified valuations, exclude retentions correctly, and know how the Construction Act payment notices work.
Typical Setup for an Electrical Contractor
- Applications for payment: You submit your monthly valuation to the main contractor. Once certified, you send a copy to the factoring provider. They advance 80-90% (minus retention) within 24-48 hours.
- Materials on account: Some providers offer a pre-delivery advance for materials ordered against a confirmed contract. This isn't standard but ask — it can make a significant difference on materials-heavy jobs.
- Multiple main contractors: If you work for several main contractors, the provider sets a credit limit on each one. Diversification across contractors is seen as positive — it reduces concentration risk.
- Domestic work: Invoice finance only covers B2B invoices. If you do domestic (consumer) electrical work, that revenue won't be financeable. Most providers are fine with a mix — they'll just exclude the domestic invoices.
Watch Out For
Retentions. The provider advances against the gross value minus retention. If your contract has 5% retention, they advance against 95% of the certified amount. The retention itself isn't released until defects liability period ends (typically 12 months). Some providers offer separate retention release facilities.
Pay-when-paid clauses. These are banned under the Construction Act (except on insolvency), but some main contractors still try. If your contract has one, it can delay payment and complicate the factoring arrangement. Get legal advice before accepting pay-when-paid terms.
