How 80% LTV compares to other bands
UK lender pricing follows a stepped LTV curve. Each step up the deposit ladder reduces the rate but with diminishing returns. Typical 5-year fixed gaps in the 2026 market look like this:
- 95% → 90%: 0.40%–0.70% improvement.
- 90% → 85%: 0.30%–0.60% improvement.
- 85% → 80%: 0.10%–0.30% improvement.
- 80% → 75%: 0.05%–0.15% improvement.
- 75% → 60%: 0.10%–0.25% improvement.
The biggest single jumps are at the top of the LTV scale. The 85%–80% step is where pricing flattens out — making 80% the practical sweet spot for many buyers who don't want to wait extra years to hit 75% or 60%.
What an 80% LTV mortgage actually costs

- Mortgage: £240,000
- Term: 30 years, capital and interest
- Monthly payment: approximately £1,205
- Total interest paid over 5-year fix: approximately £50,200

Which UK lenders compete hardest at 80%
The high-street majors all run keenly priced 80% LTV ranges — Halifax, Nationwide, Santander, Barclays, NatWest, HSBC, Lloyds, TSB and Virgin Money. Larger building societies (Coventry, Yorkshire, Skipton, Leeds, Principality) often match or undercut on niche profiles such as the self-employed, contractors, or buyers with smaller historic adverse. Specialist lenders (Pepper, Kensington, Vida, Bluestone) compete from 80% upward for credit-impaired applicants. The "best" 80% lender depends on your specific income type, credit profile and property type — not just the headline rate.
Eligibility at 80% LTV
- Credit profile: High-street lenders prefer clean files. Light historic adverse is usually accepted by mid-tier or specialist lenders at 80% LTV.
- Income type: Employed PAYE, self-employed with 2 years' accounts, contractors with day-rate evidence, and limited-company directors are all served — but the lender pool differs.
- Property type: Most standard residential, new-build (some lenders cap new-build at 85%), ex-LA, flats above commercial (specialist lenders only).
- Affordability: Standard income multiples apply; some lenders extend to 5.5× for high earners.
80% LTV vs saving for a bigger deposit
Saving the extra 5%–20% deposit usually takes 12–36 months and delivers a 0.10%–0.40% rate saving. Whether that's worth the wait depends on:
- House-price direction. Rising prices erode the rate saving and increase the absolute deposit needed.
- Rent versus mortgage gap. If renting costs more than the equivalent mortgage payment, the wait is doubly expensive.
- Personal stability. If you might move job, area or family circumstances within 2–3 years, the rate saving on a 5-year fix you can't keep matters less.
- Investment returns on the deposit fund. If your deposit is earning 4%+ in a savings account or ISA, that partially offsets the wait.
Pros
- Materially sharper pricing than 85% or 90% products.
- Almost every UK lender competes — wide product choice.
- Larger deposit smooths affordability and underwriter scrutiny.
- Better protection against negative equity if prices fall.
- Full income multiples typically available — useful for tight affordability.
Cons
- Saving 20% takes years for many buyers — opportunity cost matters.
- Marginal rate saving versus 85% is often smaller than expected.
- Larger deposit ties up capital that could be invested elsewhere.
- Hitting 80% LTV doesn't unlock the very sharpest 60% LTV pricing.
- Higher absolute deposit means more skin in the game if a transaction collapses.
