Buying a property is one of the most significant financial decisions you will ever make. The average UK house price stands at over £290,000, and the mortgage you choose will shape your finances for the next 25 to 35 years. Yet for many people, the process remains overwhelming — filled with jargon, hidden fees, and decisions that feel impossibly complex.
That is exactly why we built MortgageToolkit. Our mission is to cut through the noise and give you clear, impartial guidance at every stage of your mortgage journey. We do not sell mortgages or take commissions from lenders. Every guide, checklist, and resource on this site is written to help you make informed decisions on your own terms.

A mortgage is not just a loan — it is a commitment that typically spans two to three decades. The difference between a well-chosen mortgage and a poor one can amount to tens of thousands of pounds over the term. Consider this: on a £250,000 mortgage over 25 years, just a 0.5% difference in interest rate changes your total repayment by approximately £16,000.
Beyond the raw numbers, understanding the process gives you negotiating power. When you know what a mortgage arrangement fee should cost, when you understand the difference between a valuation and a full structural survey, and when you recognise the implications of early repayment charges, you can push back against unnecessary costs and make choices that genuinely serve your interests.
Lenders, brokers, and estate agents all have their own motivations. Our guides are written to put you — the borrower — back in the driving seat. We explain concepts in plain English, provide realistic cost ranges based on current market data, and flag the pitfalls that catch people out time and again.

Frequently Asked Questions
What types of mortgage calculators are available on MortgageToolkit?
MortgageToolkit offers a mortgage repayment calculator (monthly payments on capital repayment mortgages), a stamp duty calculator (SDLT for England & NI, LBTT for Scotland, LTT for Wales), a how-much-can-I-borrow calculator (based on income multiples), and a deposit guide tool. All calculators are updated for 2026 rates and tax thresholds.
Are MortgageToolkit's calculators accurate?
Our calculators use up-to-date formulas and tax thresholds for 2026. Mortgage repayment figures are calculated using standard amortisation formulae. Stamp duty calculations reflect current rates including first-time buyer relief. However, calculators provide estimates only — for a personalised, binding mortgage quote you should consult a qualified mortgage broker or lender directly.
What is the difference between a mortgage broker and a lender?
A mortgage broker is an intermediary who searches the market on your behalf to find suitable mortgage products from multiple lenders. A lender is the bank or building society that provides the mortgage funds. Brokers can access exclusive rates not available directly and save significant time comparing products. Most charge no fee (paid by lender on completion) though some charge an advice fee of £300–£500.
What documents do I need to apply for a mortgage?
Standard mortgage application documents include: 3 months' payslips (or 2–3 years' accounts if self-employed), 3 months' bank statements, P60 for the most recent tax year, proof of ID (passport or driving licence), proof of address (utility bill or bank statement), and details of any outstanding debts. Lenders may also request an SA302 for self-employed applicants.
