A self-build mortgage is a type of home loan designed to fund the construction of a property. It’s not limited to new-builds, it can also cover partially built projects, property conversions, major renovations, and even rebuilds.
Self-build mortgages are designed for funding construction or major renovation projects, whereas residential mortgages are used to purchase properties that are already built and ready to live in. With a self-build mortgage, funds are released in stages as the build progresses, rather than as a single lump sum.
The stages when funds are released depend on the mortgage lender. At the Vernon, we release funds after the completion of each build stage, which are typically: buying the land, laying foundations, wall plate installation, when the building is made wind and watertight, installing fixtures and plastering, and finally when the build is completed. We recommend you liaise with your project manager to ensure the funds are requested at the right intervals to maintain cash flow.
Once your self-build project is complete, you’ll need to provide your lender with three pieces of information: a Completion Certificate, Standard Buildings Insurance Schedule, and Copy of the Warranty/Architect Certificate. At this point the last stage of funds will be released for your final bills to be paid. Subject to the terms of your mortgage, you will typically be able to move onto a reduced interest rate for standard properties. At the Vernon, we offer products for borrowers in this situation.
Self-building your home gives you full control over the design, location, and quality, often at a lower cost than buying a similar property. It lets you create a home that perfectly suits your lifestyle, with the bonus of energy efficiency, long-term savings, and a real sense of pride and achievement.
However, building your own home is no small task. It requires careful planning, time, and dedication, from securing land and planning permissions to managing budgets and coordinating contractors. Unexpected delays or costs can arise, and the process can be both physically and emotionally demanding. That said, with the right support, many find the journey incredibly rewarding. The result is a bespoke home that reflects your vision, built to your standards, and tailored to your future.
As with any financial decision you should take time to carefully consider your options.
Before applying for a self-build mortgage, most lenders will expect you to have several key elements in place. This typically includes securing a suitable plot of land, obtaining planning permission, and having detailed architectural plans, along with a realistic and well-prepared cost estimate. If you don’t already own the land, you’ll also need a deposit alongside additional funds set aside to cover early expenses and any unforeseen costs.
Stamp duty is only payable on the cost of the land itself, not on the value of the property once it’s been built. Under current rules in England and Northern Ireland, you’ll only need to pay stamp duty if the purchase price of the land exceeds £125,000.
