What are retentions?

Definition

A retention is a portion of contract payment (commonly 3–5% but sometimes higher) that a client or main contractor withholds until certain milestones are met — typically practical completion and the end of a defects liability period. Retentions are widely used across electrical, mechanical, HVAC, fire protection and other building services contracts to ensure remedial work is completed.

Why retentions matter to lenders

Retentions are legally owed but they are not immediate cash. For a lender or funder this matters because:

• They reduce the value of immediately realisable receivables used as security for invoice finance.
• If retentions form a material part of your expected receipts, your working capital position can look weaker until release.
• Some lenders will advance against retention amounts only where there is independent certification, client confirmation, or a retention bond/escrow.

What are variations and why lenders care

A variation (change order) alters the original contract scope — adding or removing works, changing specification, duration or value. Variations are normal in building services but create two main issues for funders:

• Timing and certainty: an agreed and signed variation that is certified by the contract administrator can be included in funding calculations. Unagreed or disputed variations are typically excluded.
• Underwriting risk: increasing contract value may be accepted only after evidence (signed variation orders, amended interim certificates) and, in some cases, reassessment of client creditworthiness and project cashflow.

How UK Business Loans’ panel lenders typically treat retentions & variations

Different finance products treat retentions and variations in distinct ways. Below is how specialist lenders and brokers we work with usually approach them for building services firms seeking funding over £10,000.

Invoice finance & factoring

• Standard factoring advances against raised invoices. Retention amounts are often excluded from the advance until the contractor issues a release certificate or the client confirms payment.
• Specialist factors may offer retention-aware facilities or on-invoice retention funding where, once certified, a portion of the retention can be advanced (typically at a fee and lower advance rate).
• Variation orders must be signed and supported by amended invoices and interim certificates. Disputed variations are usually held back.

Retention funding / retention factoring

• Purpose-built products that let you release a percentage of retention sums earlier than contractually payable.
• Lenders look for clear retention clauses, evidence of completion milestones, client confirmation or an independent release certificate.
• Useful where retentions routinely lock up cash and affect payroll or supplier payments.

Contract / project finance & development loans

• For whole-contract underwriting, certified retentions and agreed variations are modelled into the cashflow and loan schedule.
• Lenders commonly require certified valuations, step-in rights, or an escrow/retention bond for larger projects.
• Uncertified or disputed variations will be excluded until resolved.

Asset finance, equipment loans and term facilities

• These are secured against equipment or assets so retentions have less direct impact on security value.
• Lenders still assess cashflow (including retention release timings) to ensure you can service repayments.

Bridging & short-term cashflow loans

• Bridging lenders may provide short-term liquidity where retentions or unpaid variations delay cash, but rates and fees tend to be higher and lenders will expect a clear exit (e.g., upcoming retention release date or certified payment).

Documentation lenders will ask for (quick checklist)

Having these ready speeds decisions:

• Signed contract(s) showing retention clause and percentage.
• Original and signed variation orders or change notices.
• Interim valuations, interim certificates, architect / contract administrator certifications.
• Retention release certificates or evidence of practical completion and defect sign‑off.
• Client / main contractor contact and payment history.
• Invoices, aged debtor list showing retained sums and balances.
• Any retention bond, escrow agreement or related security documentation.
• Up-to-date management accounts and cashflow forecast showing expected retention release dates.

Practical tips to improve your chances of funding

• Issue clear invoices that separate the contract sum and retention line; this helps factors calculate advances accurately.
• Obtain signed variation orders and get interim certificates updated immediately after agreement.
• Where possible get the contract administrator or QS to issue interim certification or a retention release notice.
• Consider negotiating a retention bond or escrow if a client is reluctant to release funds — some lenders accept these as security for retention funding.
• Be transparent with prospective funders about disputed variations; lenders prefer clarity and will structure offers accordingly.
• If retentions frequently cause cashflow strain, ask to be matched with specialist retention financiers via a quick form — Get Quote Now — Free Eligibility Check.

Short case study examples

These quick vignettes show common outcomes.

1. HVAC subcontractor — retention release: A £120,000 contract with 5% retention (£6,000). After practical completion and a signed retention release certificate from the main contractor, a specialist retention factor advanced 70% of the retention, avoiding a costly bridging facility.
2. Electrical contractor — variation funded: An agreed, signed variation increased contract value by £30,000. The contractor supplied the signed variation order and a revised interim valuation; the contract financier re-underwrote and advanced funds against the uplift so sub‑suppliers and labour could be paid on time.

FAQs

Will every lender advance retentions?

No. Advance against retentions is product- and lender-specific. Specialist retention funders and some factors will, mainstream banks usually do not without extra security.

Do disputed variation orders block funding?

Often yes. Lenders typically exclude disputed amounts until they are resolved or independently certified.

What size of funding do you arrange?

We match building services businesses with lenders and brokers for funding of £10,000 and upwards across a range of products.
