Using a secured loan for home improvements: what to consider

How does a secured home improvement loan work?

The lender advances money under a loan agreement secured against your home. The money can fund agreed improvements, such as a kitchen replacement, extension or loft conversion, subject to the lender's criteria.

A second charge mortgage may allow you to retain an existing mortgage deal without repaying that mortgage early. The new loan has its own interest rate, fees and repayment term. Your budget must cover both mortgage commitments.¹

Describe the proposed work accurately when discussing finance. Ask whether the lender needs quotes, permissions or further information about changes to the property's structure or condition. These requirements depend on the application.

Set the project budget before choosing the loan

Start with a written scope of work and comparable, itemised quotes. Check what each contractor includes, how long the price remains valid and whether VAT is included.²

A quote sets an agreed price for specified work. An estimate is a prediction of the likely cost. Extra work you agree to can change the bill, so record changes to scope and price in writing.³

The amount available for construction needs to cover more than the headline building work.

Ask the contractor which costs remain uncertain. A simple room refresh and structural work in an older house need different allowances. Borrowing the maximum offered should not determine the project budget.

For illustration, £28,000 of work, £2,000 of other costs and a £3,000 contingency produce a £33,000 budget. Using £5,000 of savings leaves £28,000 to fund before borrowing fees. These are invented budgeting figures, not typical renovation prices or a loan offer.

Check the money you will actually receive

Ask for the amount available for the work after any deductions. A loan described by its total balance may include fees, so that figure can differ from the cash released.

Identify broker, lender, valuation and legal fees, where applicable. Confirm when they are payable and whether they are refundable if the application does not complete. Fees added to the balance can attract interest.⁴

A useful question is: “How much reaches my account, how much do I owe at completion, and what do I pay separately?” Keep those amounts alongside the contractor's payment schedule.

How much could you borrow?

Lenders consider the property's value, existing secured borrowing, credit history and your ability to repay. Equity is the difference between the property's value and the borrowing secured against it. Having equity does not mean all of it is available to borrow.

Affordability depends on income, regular spending and financial commitments. The assessment also needs to consider relevant future changes. A property with substantial equity cannot make unaffordable monthly payments sustainable.⁵

Build your own household budget alongside the lender's assessment. Include the existing mortgage, proposed loan, essential spending and likely costs during construction. Consider whether repayments remain manageable if income falls or the interest rate changes.

Ask which property valuation the lender will use. Do not base your plans on an assumed value after an extension is finished. An improvement may add useful living space without increasing the sale price by the amount spent.

More secured borrowing also reduces the equity available if you sell. Falling property prices can make that position more difficult.⁶ Decide whether the improvement remains worthwhile if its main benefit is comfort or practicality.

Compare the full borrowing cost

Request the personalised mortgage illustration and review the following details together:

1. The amount advanced and the total amount borrowed.
2. Monthly repayments and how they might change.
3. The repayment term and total amount repayable.
4. Fees payable separately or added to the balance.
5. Charges for early repayment or overpayments.

The annual percentage rate of charge, or APRC, helps compare the overall cost of mortgage borrowing using specified assumptions. It includes interest and relevant charges, but should be read alongside the payment schedule and fees.⁷

An APRC calculation is not a prediction of future variable interest rates.⁸ Check how long any fixed rate lasts and what happens afterwards. A five year fixed rate does not mean a loan lasting fifteen years is paid off after five years.⁹

A longer term can reduce monthly repayments while increasing the interest paid overall. Ask for a shorter term comparison that still fits your budget. Consider how long the improvements are likely to serve you and whether you would still be repaying the loan when they need replacing.

Compare other ways to fund the work

A further advance from your mortgage lender

A further advance is additional borrowing from your existing mortgage lender. It usually has a separate rate from the original mortgage borrowing and remains secured against your home. The lender will assess affordability and eligibility. Ask for its costs and terms before deciding whether another secured loan is suitable.¹⁰

Remortgaging

Remortgaging can replace the existing mortgage with a new one that includes extra borrowing. Compare the cost across the whole mortgage balance, together with fees and any early repayment charge.

Keeping a favourable existing rate may matter, particularly while a fixed deal continues. As that deal approaches its end, the comparison may change. Look at the combined cost of the original mortgage and second charge loan against the proposed remortgage.¹¹

An unsecured personal loan

A personal loan may also fund home improvements. An unsecured loan does not use your home as security under the agreement, although missed repayments still have serious consequences. Compare eligibility, the amount available, monthly payments, fees and total repayment cost. The appropriate choice depends on the actual offers and your circumstances.¹²

Savings or completing the project in stages

Savings can reduce the amount you need to borrow. Keep enough accessible money for essential expenses and unexpected bills.

For work that can wait, consider completing essential repairs first and postponing optional changes. Ask whether dividing the project would create additional labour or setup costs. Compare those costs with the borrowing saved.¹³

Support for eligible improvements

Check official government and local authority guidance before financing energy efficiency work. Grants or other support may be available, depending on your location, household and proposed measures. Confirm eligibility and any application requirements before ordering work; funding should not be assumed.¹⁴

Coordinate the finance with the building work

An initial eligibility indication does not guarantee that a loan will complete. Establish when funds could be available before making commitments you cannot afford from other resources.

Agree the scope, payment stages and treatment of delays in writing. Avoid paying the whole building bill upfront.² Accepting a quote or giving a verbal instruction can create a contract, so check cancellation terms before committing.¹⁵

Ask the lender when interest starts and when the first repayment is due. Do not assume either waits until the improvements are finished.

If work is delayed or disputed, your loan repayments do not automatically stop. Keep records of the problem and seek consumer advice about the building contract. If repayments become difficult, contact the lender promptly to discuss the situation.^{3, 16}

Check permissions and insurance

Planning permission and building regulations approval are separate matters; some work needs both. Requirements differ by project and location, so check with the local authority before starting.¹⁷

Ask your insurer whether the work affects your cover and check the contractor's insurance.² Where relevant, also establish whether your mortgage terms or lease require consent. Include the cost and timing of necessary approvals in the project plan.

What if the work costs less than expected?

Money borrowed for a contingency remains part of the loan even if you never spend it. Keeping that money in a savings account does not reduce the loan balance.

Ask about overpayment allowances and any early repayment charge before returning unused funds. If you want to clear the loan completely, request a settlement figure showing what is due on the intended repayment date.⁹

Before you make a decision

A suitable funding choice should leave you able to complete the agreed work and meet the repayments afterwards. If the figures only work by assuming a higher property value, an uncertain income increase or no unexpected costs, revisit the budget.

Habitat Loans introduces customers to Loans Warehouse, where a qualified broker can assess secured borrowing options. Take your project budget, quotes, mortgage details and household spending information to that discussion.

Ask why the recommended borrowing is appropriate for your circumstances, how alternatives compare and what fees you will pay. A lender's willingness to offer a loan does not, by itself, establish that it is the right way to fund your improvements.¹⁸
