Day rate annualisation — assessing a contractor on their gross contract value rather than their accounts — is the assessment method that makes contractor mortgages work, and the lenders who apply it form a market within the market: substantial, but a fraction of the whole, with criteria that differ meaningfully beneath the shared method.
This guide maps the 2026 landscape: where day rate lending lives across the lender tiers, how the criteria differ at the points that decide cases, and the selection logic that converts the map into the right application. One standing caveat throughout: criteria move continually, so the map shows the territory’s shape — the live positions are confirmed case by case, which is the working substance of what we do.
The specialists extend day rate lending where the mainstream stops — day-one contractors, structural breadth, adverse credit alongside contractor income, and pace.
Specialist pricing buys the extension, with the mainstream remortgage planned as the standard exit.
The historic pioneer, with its minimum rate and two-years-in-profession formulation.
Known for high-LTV reach within the high street tier.
Recognised for visa-holder strength among high street lenders.
Minimum rates, history expectations and clean-credit assumptions gate entry.
The shared method: day rate × 5 days × 46 weeks at most lenders, Halifax included — a £500 rate assessing as £115,000, with standard multiples applied on top.
The label hides the differences that matter: minimum rates, history requirements, gap tolerance, structure acceptance and IR35 treatment vary lender by lender.
Day rate × 5 days × 46 weeks, with multiples typically 4.5x and higher on specialist products.
Week-count and adjustment details vary at the margins, feeding directly into maximum borrowing.
Minimum rates, history, gap tolerance, structure and IR35 treatment vary lender by lender.
The mutual sector adds two flavours: the larger societies (Accord prominently — broker-only and a specialist-broker staple — Coventry, Leeds, Skipton) running pragmatic day rate policies at mutual pricing, and the smaller manual underwriters (Saffron with its three-month threshold, Darlington, Harpenden, Buckinghamshire) reading the files the larger frameworks bounce.
Each society’s personality is mapped on its individual page; the tier’s collective value is the human reading that contractor income systematically rewards.
The selection logic runs: profile first (rate, history, structure, credit, deposit), tier second (the cheapest tier whose gates the profile clears), lender third (live criteria and pricing within the tier). Run in that order, the map produces one or two right answers per case; run backwards from a familiar name, it produces the undervaluations we spend half our time correcting.
The companion guides take the specific cuts: best lenders for contractors (the overall ranking logic), day-one contractor lenders (the new-contractor shortlist), lenders for inside IR35 (the gross-value pool), and bad credit lenders (the adverse tier) — with every named lender’s full treatment on its individual page.
A substantial market within the market — spanning high street names, building societies and specialists — but a fraction of the whole lender universe, with meaningful criteria differences beneath the shared method. The individual lender pages on this site map each one's personality in depth.
