Private, domestic property is an asset held in high esteem by most baby boomers, not least because many recognise the good fortune which has accrued from their long-term ownership of bricks and mortar.
Buying a family home in the 1980s or 90s has enhanced the wealth of millions of people through capital growth. Many owners have also continued to upgrade their property during their period of ownership. Adding a new driveway, heating system or roof, for instance, can improve a home’s appeal, comfort and condition, although the cost is not necessarily reflected pound for pound in its market value.
Note, however, that not every project results in an immediate financial return. Some succeed primarily in making a property more comfortable, while others may also enhance its value over the medium to longer term. None comes with a guaranteed uplift.
Hillarys’ UK Home Renovation Trends and Statistics report highlights the varied reasons people improve their homes, including changing family circumstances, working patterns and accessibility needs.
Saving energy is another consideration, alongside creating more usable living space. A home office, an extra bedroom or accommodation better suited to later life may make a substantial difference to day-to-day living.
For those planning to stay put for many years, comfort, safety and practicality can matter just as much as the eventual sale price.
Bearing this in mind, it begs the question: what level of return could I expect from adding, say, a home office, loft conversion or extension? The answer will depend on the area, the property, the quality of the work and what local buyers are willing to pay. Extra usable space can add value, but there is no universal percentage uplift. A local estate agent or surveyor can help assess the likely effect before you commit.
For eligible older homeowners considering equity release to fund a property upgrade, the arithmetic deserves a careful look. The potential added value is one part of the picture; the cost of borrowing is another.
The amount homeowners can release from their property depends primarily on their age, the property’s current market value and the lender’s criteria. Health and lifestyle can sometimes affect the options available. A lifetime mortgage allows eligible homeowners, usually aged 55 and over, to borrow against their home while retaining ownership. With a roll-up lifetime mortgage, there is no requirement to make monthly repayments, although borrowers must continue to meet the terms of their plan. Voluntary repayments may be possible, subject to the lender’s conditions.
If no interest payments are made, interest is added to the loan and further interest is charged on the growing balance. The loan and outstanding interest are normally repaid from the sale of the property when the last remaining borrower dies or moves permanently into long-term care.
Lifetime mortgages meeting the product standards of the Equity Release Council, the industry’s trade body, include a no-negative-equity guarantee. This means that, provided the loan terms have been met and the property is sold for the best price reasonably obtainable, neither the borrower nor their estate will owe more than the sale proceeds after reasonable selling costs. Equity Release Supermarket is a member of the Council and provides independent, whole-of-market advice.
So where might a loft conversion fit into the picture? It can provide a room to enjoy now and potentially make the home more valuable later. But those benefits need to be weighed against the project budget and the long-term borrowing cost.
Let us consider an illustration. Assume a married couple, both aged over 55, own a mortgage-free home worth £300,000 and, subject to eligibility, borrow £45,000 through a lifetime mortgage to fund a loft conversion. For simplicity, assume the building work costs exactly £45,000; any mortgage, advice or legal fees would need to be budgeted for separately.
Suppose the completed work increases the property’s value by 12%, taking it to £336,000. That is an illustrative assumption, rather than a prediction or a guaranteed return. At this stage, the £36,000 increase in value would be less than the £45,000 spent.
Now assume both the improved home and an otherwise comparable, unimproved property increase in value by an average of 2.5% a year over the next decade. This is a hypothetical growth rate, not a forecast: house prices can fall as well as rise.
On those assumptions, the improved home would be worth approximately £430,108 after ten years, compared with £384,025 for the unimproved home. The difference would be around £46,083. These are property values before deducting any mortgage debt or selling costs.
That does not mean the conversion has paid for itself. The £45,000 loan would still need to be repaid, together with any accumulated interest. To illustrate the importance of that cost, at an assumed 6% annual compound interest rate, with no repayments, further borrowing or fees added, the balance would reach approximately £80,588 after ten years. This is a simplified example, not a product quotation; actual costs depend on the plan’s rate and interest calculation method.
Future house-price growth may help offset some of the cost, but it cannot be relied upon to cover the project or the borrowing. Nor does an increase in the property’s gross value necessarily mean an increase in the equity left for the homeowners or their estate.
The strongest reason for undertaking the work may be the extra space and enjoyment it brings: somewhere for visiting grandchildren to sleep, a hobby room, or a home better suited to the years ahead. Any added value is a potential benefit, rather than a promise that the work will fund itself.
Before committing, obtain detailed quotations, allow for contingencies, and check any necessary planning permissions and building regulations requirements. Discuss the proposed structural work with the lender before it starts, as consent and conditions may apply. A lifetime mortgage will reduce the equity available to your estate and could affect entitlement to means-tested benefits. Taking advice from a qualified equity release adviser is required before arranging a lifetime mortgage and will help you compare the long-term costs with alternatives, such as using savings or other suitable borrowing.
