Most developers think lender due diligence stops at GDV, LTV, and planning status. It doesn't anymore. How you run your site - how you pay your subcontractors, whether your CDM obligations are in order, what happens when a groundworker is struggling - is showing up in underwriting conversations.
Here's what you need to know before you go to market for development finance.
Fair Pay Is a Lender Signal, Not Just a Legal Obligation
Every UK construction site must pay at minimum the National Living Wage. That's not optional - it's the law under the Employment Rights Act. But if you're seeking public funding, the bar is higher.
Homes England partners are expected to align with the Real Living Wage and demonstrate compliance with the Fair Payment Code - a government-backed standard that requires 95% of invoices paid within 30 days (Gold tier). The Procurement Act 2023 extends the 30-day obligation down through your entire subcontractor chain on any project with public money in it.
If you're a developer with a reputation for paying late, that is now a lender risk signal.

CDM 2015 - Your Obligations Start Before a Spade Goes In
The Construction (Design and Management) Regulations 2015 place legal duties on clients from day one - before any groundwork begins. Principal contractor, principal designer, construction phase plan: these aren't optional extras reserved for large schemes.
An HSE enforcement notice mid-build is a loan covenant event. It stops your site. It stops your drawdown. It creates a cost overrun you haven't budgeted for. Lenders know this, and experienced underwriters will ask whether your CDM duty holder appointments are in place.
CHAS, Constructionline, or any SSIP member scheme accreditation signals competence before you've broken ground. Get it in place before you approach lenders - it removes a question before it gets asked.

ESG Lenders Are Tying Drawdown to Social Value
NatWest, Lloyds, Aviva, Legal & General - the major institutional funders of UK residential development - have adopted sustainability-linked lending frameworks. On larger schemes, your interest rate or drawdown conditions can be tied to social value metrics: supply chain payment compliance, Modern Slavery Act adherence, and worker welfare.
The National TOMs framework is used by Homes England and the GLA to evaluate bids on public-sector-linked projects. If your scheme has any public funding component, expect to be assessed against it.
This isn't something coming in the future. It's in loan agreements now.

Worker Wellbeing - The Question Lenders Are Starting to Ask
Construction has the highest suicide rate of any UK industry. The Lighthouse Club and CIOB Mental Health Charter exist because the industry needed them.
Beyond the human case - which is the only case that matters - an ESG-minded lender comparing two similar schemes will increasingly favour the developer who has thought about this. A basic site wellbeing policy takes an afternoon to put in place. At due diligence stage, it's the kind of detail that signals a professional operator.
What This Means for Your Evidence Pack
Site welfare failures - HSE notices, underpaid workforce disputes, Modern Slavery breaches - are loan impairment events. Experienced underwriters know it. Brokers placing deals with institutional lenders are being asked about it.
