Funding Circle and iwoca anchor the mainstream unsecured panel: a fixed-term loan or a flexi-draw facility with no asset named as security, though almost all still require a director personal guarantee. White Oak UK explicitly covers unsecured term loans alongside its asset finance line, and Cashplus Bank runs small unsecured loans up to around £25k for thinner-file directors that mainstream lenders decline. This FundBiz ranking assesses 4 UK lenders for "best uk unsecured business loans", weighting primarily on genuine unsecured availability (35%), transparency (20%), decision speed (20%) (see the full weighted criteria below). Scores are our own desk-research assessment built from the FCA Register, Companies House filings and each lender's published product criteria, not customer reviews and not paid placement. Inclusion is never paid for: FundBiz is paid by lenders on completed funding, not for a verdict, and commission never changes a position. Match against the panel in two minutes with a soft search only.

What is the best UK unsecured business loan?
Funding Circle and iwoca anchor the mainstream unsecured panel: a fixed-term loan or a flexi-draw facility with no asset named as security. White Oak UK explicitly covers unsecured term loans, and Cashplus Bank runs small unsecured loans for thinner-file directors.
What does "unsecured" actually mean on a UK business loan?
No specific business asset is named as security for the facility. It does not usually mean no personal guarantee: almost every lender on this list still requires a director PG, which is a personal commitment rather than a charge over a named asset.
What does a UK unsecured business loan cost?
Funding Circle prices 6.9% to 26.9% APR. iwoca prices from 2% per month on drawn balance. White Oak UK and Cashplus Bank both quote at offer rather than a headline rate.
How fast can an unsecured business loan fund?
iwoca decides same day to 24 hours. Cashplus Bank decides in 1 to 3 business days. Funding Circle decides in 1 to 3 business days. White Oak UK decides same day to 5 business days depending on the case.
What unsecured loan applications get declined?
Sub-12-month trading and recent CCJs or missed payments are the most common declines at Funding Circle. iwoca and Cashplus Bank are both more accommodating on thinner files, and White Oak UK's professional-practice line adds a further route for regulated firms.
