£100,000 Secured Loan UK — Can I Get a 100k Loan on a House?

Yes — UK homeowners can borrow £100,000 against their property as a secured loan (also called a homeowner loan or second charge mortgage) provided they have sufficient equity, verifiable income to service the new payment, and a credit profile that fits a panel lender. Most UK lenders cap combined LTV at 80-85%, so to borrow £100k on a £300,000 property with a £150k first charge mortgage you'd be at 83% combined LTV — within range for several panel lenders.

At June 2026 panel rates and a 10-year (120-month) term, monthly payments on a £100,000 UK secured loan are approximately: £1,130/month at 6.34% APRC (prime clean credit, sub-50% LTV via Selina Finance); £1,208/month at 7.91% APRC (clean credit median); £1,294/month at 9.50% APRC (minor adverse credit); £1,476/month at 12.90% APRC (heavy adverse credit).

Most lenders on our 12-strong UK specialist panel accept £100,000 secured loan cases — including Selina Finance, Pepper Money, United Trust Bank, Together, Spring Finance, Central Trust, West One, and Norton Finance. Some smaller specialists (Equifinance, Mercantile Trust) cap at £150,000 maximum so a £100k loan sits well within their range. Adverse-credit specialists Evolution Money and Step One Finance cap at £50,000 maximum, so do not lend at the £100k size.

You need sufficient equity to keep your combined LTV (existing first charge mortgage + new £100k loan) within the lender's cap — typically 80-85%. On a £300,000 property with a £150k first charge mortgage, taking out a £100k second charge puts you at 83% combined LTV — within range. On a £200k property with a £100k mortgage, the same £100k second charge puts you at 100% LTV — outside almost all lender criteria. The higher your property value relative to your first charge balance, the more achievable a £100k second charge is.

There's no single income threshold for a £100k UK secured loan — FCA rules require all lenders to complete an affordability assessment based on disposable income after existing commitments (mortgage, household bills, dependents, other credit). At June 2026 rates a £100k loan over 10 years costs around £1,130-£1,476/month depending on rate tier. Lenders typically want to see the new payment comfortably covered by net monthly income. PAYE, self-employed (SA302), pension, and benefit income are all accepted.

It depends on your existing first charge mortgage. If you have a cheap legacy 2021 fix (sub-2.5% APR) — like ~1.8 million UK homeowners whose fixes expire in 2026 — a £100k secured loan typically wins because it preserves the cheap legacy rate on the original mortgage. Remortgaging for £100k more means refinancing the whole mortgage at current rates (average 5-year fix around 5.7% in May 2026), surrendering the cheap legacy fix. The blended cost of preserving the 2.1% first charge + adding a 6.34% second charge on £100k is materially lower than remortgaging the whole £200k+ balance at 5.7%.

Typical completion time is 3-4 weeks from application to funds release. £100,000 cases usually require a physical RICS property valuation (rather than an automated valuation) because the loan size is large enough to justify the £200-£450 valuation fee. Decisions in principle issue within 24-48 hours; valuation runs 5-12 days; legal work 12-20 days; completion 20-28 days. Faster completion (7-10 days) is possible on some panel lenders' fast-track products at modestly higher pricing.

Yes — but the lender panel is narrower at the £100k size. Pepper Money, Norton Finance, and Together accept minor-to-moderate adverse credit at £100,000 with rates from around 8.5% APRC for minor adverse to 12% for moderate. Heavy adverse specialists like Evolution Money and Step One Finance cap at £50k maximum, so they don't lend at the £100k size — meaning the heaviest adverse profiles are restricted to smaller loans.
