[Read the full definition of Self-build mortgage](https://mortgagelane.com/definitions?term=self-build-mortgage) ## Specialsit Self Build Lender Access Speak to a Mortgage Lane adviser about your options. ## In short Self-build lenders differ most in when they release money, with arrears-stage lenders paying after each stage is finished and advance-stage lenders paying before it, which decides how much working capital a borrower needs of their own. **A self build mortgage funds the construction of a home rather than the purchase of an existing one, and the funds are released in stages as the build progresses.** That staged release is what makes self build lending a different market from standard residential lending, and it is why the lender list is short. Lenders assess a self build case on land ownership, build costs, construction method, the stage payment structure, and the borrower's ability to complete the project within the agreed budget and timeframe. Structuring the case correctly at the outset is what avoids funding delays, valuation issues, and declines mid-build. Mortgage Lane arranges [self build mortgages](https://mortgagelane.com/short-term-finance/self-build-mortgages) across the UK for first-time self-builders and experienced developers, identifying lenders whose criteria align with the project type, construction method, budget, and stage payment requirements. ## What is a self build mortgage? **A self build mortgage is a specialist loan that finances the construction, or heavy renovation, of a home.** A self build mortgage differs from a traditional mortgage, which funds the purchase of a property that already exists. Funds on a self build mortgage are released in stages reflecting the progress of the construction project, rather than as a single advance on completion. ## Key features of a self build mortgage - **Stage payments.** Funds are released incrementally as construction stages complete, such as after the foundations are laid or when the property reaches a watertight state. - **Custom requirements.** Self build mortgages carry their own criteria for inspections and valuations, reflecting the fact that the security does not yet exist in finished form. - **Flexibility.** Self build mortgages offer greater flexibility in loan amounts and repayment structures than standard residential mortgages. ## Self build mortgage lenders in the UK **Self build lending is concentrated among building societies rather than high street banks, and each sets its own maximum Loan to Value and stage payment structure.** Three lenders active in the market: **Beverley Building Society** Maximum Loan to Value of 80%. Beverley Building Society is known for competitive rates and flexibility across self build projects, and supports both new builds and extensive renovations. **Buckingham Building Society** Maximum Loan to Value of 85%. Buckingham Building Society offers flexible terms and stage payments across a range of self build projects, including bespoke and traditional builds. **Dudley Building Society** Maximum Loan to Value of 85%. Dudley Building Society offers tailored solutions with support through the construction process, covering new builds and significant renovations. Lender criteria change. Confirm current terms with the lender or with a broker before relying on any figure above. ## How to choose a self build mortgage lender **On a self build mortgage the stage payment structure matters more than the headline rate, because a mismatch between the lender's release points and your build schedule can stall the project.** Six things to compare: 1. **Stage payment structure.** Check the lender's release points against your construction schedule. Lenders differ in the stages at which they release funds and in what evidence they require at each stage. 2. **Loan terms and rates.** Compare interest rates and terms, and check the term aligns with your construction timeline rather than just your budget. 3. **Eligibility criteria.** Review each lender's requirements on credit history, income verification, and the types of self build project they will support. 4. **Fees and charges.** Account for arrangement fees, valuation fees, inspection fees at each stage, and any early repayment charges. 5. **Flexibility.** Self build projects encounter changes and delays. A lender that can adjust the loan or the payment schedule is worth more than one that cannot. 6. **Support through the build.** Some lenders offer guidance on inspections, stage sign-off, and compliance with building regulations. Others release funds and leave the management to you. > [!TIP] > ## Key Features of Self-Build Mortgages: > > 1. **Stage Payments:** Funds are released incrementally based on the completion of various construction stages, such as after laying the foundation or when the property reaches a watertight state. > 2. **Custom Requirements:** These mortgages are tailored to the unique needs of self-build projects, including specific criteria for inspections and valuations. > 3. **Flexibility:** Self build mortgages offer greater flexibility in terms of loan amounts and repayment structures compared to standard mortgages. ## Self Build Mortgage Lenders: frequently asked questions **What is the difference between a self-build mortgage and a standard mortgage?** A self-build mortgage is designed for funding the construction of a new home, whereas a standard mortgage is for purchasing an existing property. **Can I use a self-build mortgage for renovation projects?** Yes, many lenders offer self build mortgages for renovation projects, but it’s essential to confirm with the lender. **How long does the approval process take for a self-build mortgage?** The approval process can vary but typically takes several weeks.
