Harpenden Building Society is a small mutual specialising in manual underwriting of the cases volume lenders cannot read — complex income, unusual property and genuinely individual files. It is a precision tool for the compound contractor case with a sound underlying story, not a lender for the simple case. This guide covers how it assesses income and where it fits.
Approach is stable; figures are confirmed at application.
Harpenden underwrites entirely by hand: criteria are starting points, and underwriters discuss cases directly. That makes it a home for the compound file — layered non-standard income, an unusual structure, or non-standard property alongside contractor income. Files are built as an argument for lending rather than fed through a scorecard. For a contractor whose case needs assembling and explaining, that is precisely the value.
Harpenden reads contractor income manually, with the day rate annualised in the standard way where it applies:
Day rate x 5 days x 46 weeks = assessed annual income
A £500 day rate assesses at £115,000; at a standard 4.5x that is around £517,000 of indicative borrowing — illustrative, and dependent on your circumstances and Harpenden’s live criteria. The value is in how it reads the parts that do not fit a template.
A typical application is a well-assembled file: contract, work history, the full income picture, and — where relevant — detail on non-standard property. As a small society, pricing sits above the volume market, and capacity is finite; the premium buys the conversation and consideration. Its sweet spot is the genuinely individual contractor case, including unusual property, not the straightforward one.
Illustrative only, using the standard 5 x 46 method and a typical 4.5x multiple; Harpenden reads the whole case manually.
Harpenden builds lending decisions from a well-argued file, so assemble the case as an argument: the full income picture (all strands), the work history, and — where the property is non-standard — detail on its construction or use. The clearer the story, the better its underwriters can say yes.
Because capacity is finite and pricing sits above the volume market, Harpenden is worth reserving for the case that genuinely needs it rather than a simple one.
Harpenden suits the genuinely individual case — layered non-standard income, an unusual structure, or non-standard property alongside contractor income — that volume lenders cannot process. It is a precision tool for the compound file.
It suits you less well if your case is straightforward, where a mainstream lender will be both simpler and cheaper.
The compound, individual file — layered non-standard income, unusual structures or property — assessed manually rather than scored. Exact terms are confirmed at application.
Entirely — criteria are starting points and underwriters discuss cases directly. Files are built as an argument for lending.
Yes — its manual flexibility extends to non-standard construction and individual property alongside the income. Specifics are confirmed at application.
On the day rate annualised in the standard way (rate x 5 x 46) where it applies, read manually alongside the wider case.
Yes to both, with appropriate income evidence for each structure.
Small-society pricing sits above the volume market — the premium buys the conversation and consideration for a genuinely individual case.
Yes — its manual flexibility extends to non-standard construction and individual property alongside complex contractor income, which is much of why contractors use it. Present detail on the property so the underwriter can assess it. Specifics are confirmed at application.
For the genuinely complex case it often is — the premium buys manual consideration and a lending decision that volume lenders simply cannot offer. For a simple, clean case it is not worth it, and we would place you with a cheaper mainstream lender instead.
