Secured Loan for £100,000

Monthly Payment Estimates for a £100,000 Secured Loan

Representative capital-and-interest monthly costs for a £100,000 second charge at three APR bands:

Term	At 7.0% APR	At 9.0% APR	At 12.0% APR
10 years	£1,161	£1,267	£1,434
15 years	£898	£1,014	£1,200
20 years	£775	£900	£1,101
25 years	£707	£839	£1,053

Total cost of credit on £100,000 over 15 years at 9.0% APR is around £82,520, total repayable approx £182,520. Over 25 years the total repayable climbs to around £251,700. Term selection has an enormous total-cost impact at this scale — a 10-year rather than 25-year term saves over £100,000 of total interest at the same rate.

Prime pricing below 60% CLTV comes from United Trust Bank and Shawbrook. Near-prime 60-80% CLTV from Pepper Money, Precise Mortgages and Shawbrook. Adverse-credit or high-CLTV cases sit with Together Money, Evolution Money, Spring Finance and Norton Home Loans at rates typically 2-4 percentage points higher.

What £100,000 Can Fund

£100,000 funds transformational work. Common uses: two-storey rear or wrap-around extension (£90,000-£200,000 total cost), combined loft and basement conversion, comprehensive high-spec whole-house refurbishment, sideways extension or garage conversion into habitable space, deposit plus fees on a significant buy-to-let purchase (subject to unregulated business regime), or major portfolio debt consolidation.

At £100,000 almost every use case involves professional contractors, architects and structural engineers. Staged drawdown tied to milestone completion is common practice — Pepper Money, Shawbrook and Together Money all support this, paying contractor invoices directly. A JCT or equivalent fixed-price building contract is strongly advised to control scope creep.

Business-purpose £100,000 second charges (limited-company buy-to-let, property-trade inventory, trading business funding) fall outside MCOB and into an unregulated commercial regime handled by Shawbrook Commercial, UTB Bridging, Together Commercial and specialist lenders. Pricing is typically 1-2 percentage points higher and the ESIS, reflection period and FOS/FSCS protections differ materially. Take independent legal advice before proceeding with any unregulated transaction.

Eligibility, Income and Affordability

Affordability testing at £100,000 is rigorous. Monthly payments typically run £800-£1,450 depending on rate and term. Lenders add 1-3 percentage points to the pay rate and test against net household income after existing commitments and the first mortgage.

Typical minimum income: £50,000+ gross household on joint applications, £40,000+ for sole applicants, though net affordability headroom is the true test. Clearing smaller unsecured balances and cancelling unused credit facilities before applying materially improves the affordability picture.

Self-employed applicants supply two years of SA302s, tax year overviews and business bank statements; Pepper Money and Precise Mortgages may accept one year with exceptional affordability. Limited-company directors usually combine salary, dividends and sometimes retained profit; an accountant’s reference strengthens the case. Contractors annualise day rate. Adverse-credit cases are still possible at £100,000 but the panel narrows to Evolution Money, Norton Home Loans, Spring Finance and Together Money.

Equity, LTV Bands and Lender Pricing

At £100,000 CLTV is the single most important rate driver. Lenders publish tightly banded products and even a 5% CLTV shift can change your rate by 50-100 basis points.

Combined LTV	Prime APR band	Example lenders
Up to 60%	7.0% - 8.1% APR	Shawbrook, UTB
60% - 75%	8.0% - 9.5% APR	Shawbrook, UTB, Pepper
75% - 85%	9.5% - 11.4% APR	Pepper, Precise, Spring
85% +	11.8% - 14.9% APR	Evolution, Norton, Together

Worked example: £800,000 property, £450,000 first mortgage, £350,000 equity. Adding £100,000 takes combined borrowing to £550,000 — a 68.8% CLTV, prime territory. On a £700,000 property with the same mortgage, CLTV is 78.6%, near-prime pricing tier.

A physical valuation is always required at £100,000, frequently with a senior-surveyor review. Prepare robust comparable evidence and give full access to all property improvements. At this size under-valuations can cost £500-£1,000 because you may have already paid the valuation fee, so pre-application desktop comparison is invaluable.

Second Charge vs Further Advance vs Remortgage

At £100,000 the three-way route comparison is critical because absolute cost differences between routes can easily exceed £10,000 over 3-5 years.

Further advance: fastest and cheapest in arrangement fees if available from the first-charge lender. Capped by the lender’s own CLTV. Priced off the lender’s standard range, which may or may not be competitive.

Full remortgage: restructures the entire mortgage to include the £100,000 at a blended market rate. Best if out of tie-in or ERC is small. If still in a fix, ERC (1-5% of balance) can run to £10,000-£25,000 on a mid-sized existing mortgage.

Second charge: preserves a competitive existing rate. Priced above mainstream remortgage rates but often cheaper overall once ERC avoidance is factored in.

Worked example: £400,000 mortgage at 3.7% fixed with 3 years remaining and 3.5% ERC. Remortgage to £500,000 at 5.4% market rate: ERC £14,000 + £2,000 fees, new monthly around £3,200 (vs current £2,086) = net new cost £1,114/month for the £100,000. Second charge at 8.8% APR over 15 years on £100,000 costs about £1,004/month and avoids ERC — cheaper over the tie-in. A broker should model both over a realistic horizon.

Application Journey and Typical Timescales

A £100,000 application typically completes in five to eight weeks. The flow: detailed fact-find with broker, DIP (soft searched), full application, physical valuation and potentially a senior-surveyor sign-off, underwriting, offer, seven-day reflection period, completion.

Prime cases with United Trust Bank, Shawbrook, Pepper Money or Precise Mortgages at low CLTV complete in 25-35 working days. Near-prime 30-40 days. Adverse-credit cases through Evolution Money, Norton Home Loans or Together Money 35-60 days because each adverse item and each piece of income evidence is manually reviewed.

Documents on day one: three months payslips or two years of SA302s plus tax year overviews, three months main bank statements, ID, proof of address, latest first mortgage statement, buildings insurance schedule, recent council tax bill, accountant’s reference (self-employed), JCT or equivalent build contract (if funds are for construction). Joint applicants duplicate. A complete pack compresses timelines by 10-14 working days.

Fees, APRC and Worked Cost Example

Typical fees at £100,000: lender arrangement £1,995-£3,495, broker fee £0-£10,000, valuation £450-£1,000, legal/title insurance £400-£1,000. All disclosed on the ESIS.

Worked example: £100,000 at 8.4% nominal over 15 years with £2,995 lender fee added. Monthly payment approx £979, total cost of credit approx £76,200, APRC approx 9.0%. Adding a £5,000 broker fee raises APRC to around 9.5%; a £10,000 broker fee raises it closer to 10.1%.

Broker fees at £100,000 demand careful scrutiny. A 10% broker fee is £10,000 — a meaningful sum. Shopping between 2-3 FCA-authorised brokers and negotiating the fee typically saves £2,500-£5,000. Under FCA rules broker fees must be disclosed in writing before application and cannot be taken until completion on regulated mortgages. Never accept a broker fee agreement without reading the cancellation and refund terms.

Regulation, Protections and Mistakes to Avoid

Personal-purpose £100,000 second charges are FCA-regulated under MCOB. Lenders must stress-test affordability, issue an ESIS showing APRC and total cost of credit, respect the seven-day reflection period, and treat customers in financial difficulty fairly. FOS handles complaints free of charge with award limits up to £430,000 for acts from April 2025. FSCS protects eligible claims up to £85,000.

Common mistakes at £100,000: failing to run a proper three-way route comparison; under-estimating the APRC impact of broker fees; stretching to 25-year terms where 15 would save £50,000-£100,000 in total interest; neglecting ERC-free tracker options; and not stress-testing affordability against a 3% rate rise or a meaningful income drop.

Always verify lender and broker status on the FCA register (fca.org.uk). Business-purpose £100,000 loans fall outside MCOB regulation and carry different protections — your broker must tell you clearly, in writing, if the case is unregulated. Use the full seven-day reflection period to compare APRC across alternatives before signing the offer.
