Quick Answer
Self-employed it contractors can get mortgages in the UK, but most lenders require 2–3 years of accounts or tax returns. A specialist broker can help find lenders with more flexible criteria.
- Loan-to-value bands (95/90/85/80/75%) drive pricing — check the nearest band boundary
- Compare total cost over the fixed period — rate plus fees, not headline rate alone
- Get a soft-search decision in principle first — it costs nothing and reveals problems early
The Details That Decide Outcomes
The remortgage window is a free option too few people use. Most lenders let you secure a new rate up to 6 months before your current deal ends — if rates rise you're protected, and many lenders let you switch to a cheaper deal before it starts.
Post-2023 affordability testing is stricter than many buyers expect. Lenders now stress-test your payments at a notional higher rate, and regular commitments — car finance, childcare, even subscriptions — reduce the maximum loan. Trimming commitments 3 months before applying genuinely increases what you can borrow.
Nothing moves your rate more than loan-to-value. Lenders price in bands — 95%, 90%, 85%, 80%, 75% — and crossing a band boundary can cut your rate by 0.3–0.6 percentage points. Ask your broker to model both sides of the nearest band: on a £200,000 loan that's £2,000–£5,000 over a fix.

Frequently Asked Questions
The majority of lenders require at least 5–10% of the property price. Rates improve sharply once you pass 15–20% — the biggest pricing jumps happen at 90%, 85% and 75% loan-to-value.
Most offers are valid for 3–6 months. New-build purchases often get extended validity because completion dates slip.
Usually yes, but the pool of lenders shrinks. Specialist lenders accept defaults and CCJs older than 12 months, typically at higher rates. A broker who works with adverse-credit lenders is essential here.
A decision in principle usually uses a soft check, which leaves no mark on your score. The full application is a hard check — which is why you should pick your lender before applying, not after.
It depends on your appetite for rate risk. A 5-year fix buys certainty; a 2-year fix costs less if rates fall. Check the total cost including fees, not just the headline rate.
Expect roughly £2,000–£4,000 covering valuation, legal work, searches and any lender arrangement fee. First-time buyers get stamp duty relief on lower-priced homes.
