The short answer: a renovation loan is not a single product. It is any borrowing used to fund home improvements, from a home loan top-up to a construction loan or an unsecured personal loan. The right structure depends on your project size, whether you have equity, and whether the work is structural.

At Noma Finance, we map your renovation to the right lending structure first, then compare options from our lender panel, so you can review the estimated total cost before you sign, not just the monthly repayment. A common order to consider is: your own money first (redraw or offset), then a home loan top-up at home loan rates, a construction loan for structural work, and a personal loan where equity is limited or the job is small. The most suitable structure will often depend on your project size, available equity and the type of work involved.

Key takeaways

  • A renovation loan is a category, not one product. It covers home loan top-ups, redraws, refinancing, construction loans, personal loans and green loans.
  • A home loan top-up can be a lower-rate option for some borrowers, but it adds to your mortgage and depends on your lender, equity and loan terms.
  • Construction loans are commonly used for major structural work and release funds in stages as the build progresses.
  • Personal loans may suit smaller projects or situations where you have limited equity, although the interest rate is often higher than secured borrowing.
  • The lowest monthly repayment and the lowest total cost are often not the same loan. A broker compares both.

What is a renovation loan and how does it work?

A renovation loan is an umbrella term for any finance used to pay for home improvements. Most Australian lenders do not sell a single product called a renovation loan. You are choosing between a top-up, a redraw, refinancing, a construction loan, a personal loan or a green loan.

One fork decides most of it: is the work cosmetic or structural?

Cosmetic vs structural renovations, and how each is funded

Feature Cosmetic (non-structural) Structural (major)
Examples Paint, flooring, kitchen, bathroom, landscaping Extensions, second storey, removing load-bearing walls
Rough guide only Often under about $100,000 Often over about $100,000
How you fund it Top-up, redraw or personal loan Construction loan
Valued on Current property value Estimated value once the renovation is complete
Builder and council Usually not required Licensed builder plus DA or CDC

A bank can only offer its own products. A broker compares lenders and maps the structure to your renovation. If you want to see how that comparison differs from walking into your own bank, our guide on using a finance broker versus a bank walks through it.

What are the different home renovation loan options?

There are six main ways to finance a home renovation in Australia.

  • Home loan top-up. Borrow against your equity at home loan rates. A lower-rate option for some borrowers.
  • Redraw facility. Withdraw your own extra repayments. No new loan, same rate, usually sooner than new borrowing.
  • Replace your mortgage with a larger one, sometimes reviewing your rate at the same time.
  • Construction loan. Staged funding for structural work.
  • Personal loan. Unsecured, can be suitable where no equity is available.
  • Green loan. A discounted rate from some lenders for eligible energy upgrades.

One product is missing on purpose. Credit cards and buy now pay later (BNPL) can carry higher interest rates than secured borrowing, so they are generally better suited only to very small incidentals.

Home loan top-up (often a lower-rate option)

You increase your existing mortgage against the equity you have built. Owe $400,000 on a home worth $700,000, and you could lift the loan to around $560,000 (80% of value) for the works, subject to approval.

Indicative rates vary by lender, loan type and borrower profile. The trade-off: a top-up adds to your mortgage, so repayments rise or the term lengthens. Top-ups are often offered on variable loans, and you usually need to keep your loan-to-value ratio (LVR) at or below 80% to avoid Lenders Mortgage Insurance (LMI).

Redraw facility

If you have made extra repayments, you can withdraw them. This is not new borrowing, so there is no new application, and the rate does not change. The catch: not every loan has redraw, and pulling funds out reduces your buffer.

Refinancing your mortgage

You replace your home loan with a new, larger one. It may suit fixed-rate borrowers who cannot top up, or borrowers seeking to review their rate at the same time. Watch the costs: break fees on fixed loans ($2,000 to $10,000 or more), discharge fees ($150 to $400) and a fresh valuation ($300 to $600), all illustrative. Check the rate savings cover these first.

Construction loan (for structural work)

Commonly used for extensions, second-storey additions, knock-down rebuilds, or any work needing a licensed builder and council approval. Funds are released in stages as the build progresses (slab, frame, lock-up, fixing, completion), and you pay interest only on what is drawn.

You will need a fixed-price building contract, council approval (DA or CDC), detailed plans and builder's insurance. Approval time varies by lender and project complexity. Budget 10% to 20% contingency on top of the contract sum.

Personal loan (no equity needed)

An unsecured personal loan is a lump sum, usually $5,000 to $75,000, repaid over one to seven years. It can often be processed sooner than secured options, depending on the lender and your documents, and no property valuation is needed. Rates vary by lender and borrower profile, and unsecured loans are often priced higher than secured borrowing such as a top-up.

Monthly repayments may be higher than a top-up, but because the loan term is usually shorter, the total interest may be lower. More on that below. If you are weighing a personal loan, our guide to what counts as a good personal loan rate is worth a read first.

Green and energy efficiency loans

If the work includes solar, batteries or insulation, you may qualify for a discounted rate from some lenders. Check whether any part of your project qualifies before you settle on a structure.

Renovation finance at a glance

Ways to fund a renovation, compared

Option Indicative rate Best for Approval time
Home loan top-up Home loan rates Cosmetic to mid-size renos, equity available 2 to 4 weeks
Redraw facility Your existing home loan rate Smaller projects, extra repayments available Usually sooner
Refinancing New home loan rate Fixed-rate borrowers, rate review 3 to 6 weeks
Construction loan Varies, interest charged on drawn funds only Major structural work, extensions 4 to 8 weeks
Personal loan Often higher than secured borrowing Smaller projects, limited equity 1 to 3 days
Green loan Discounted (varies) Solar, batteries, energy upgrades Varies

Indicative only. Rates and approval times vary by lender, loan type, application complexity and borrower profile.

How much can you borrow for a home renovation?

Using home equity (top-up or refinance)

Many lenders cap borrowing at 80% of your property's current value, minus your existing loan. That is your usable equity.

How much usable equity three homeowners could access

Scenario Property value Current loan Usable equity (80% LVR)
First renovation $800,000 $500,000 $140,000
Established homeowner $1,200,000 $400,000 $560,000
Recent buyer $750,000 $600,000 $0 (other options may suit)

Figures are illustrative only. Borrow past 80% LVR and you may trigger LMI. LMI costs vary depending on the loan amount, lender and LVR. If you are a recent or first-home buyer with little equity, our rundown of first home buyer schemes for 2026 may be a better starting point than a renovation loan.

Using a construction loan

The lender assesses the property's "as if complete" value, meaning its estimated value once the work is finished. A renovation may affect the property's value, which can influence how much you may be able to borrow, subject to lender assessment.

Using a personal loan

Unsecured loan limits vary by lender and are often lower than secured borrowing. Some lenders may offer higher amounts where security is available.

Serviceability still matters

Whichever path you take, lenders also assess serviceability using a buffer above the interest rate, in line with regulatory and lender policy requirements, so the rate used for assessment is higher than the advertised rate. The income you need therefore depends on your existing debts, not just the loan size. Two people borrowing the same amount can get different answers based on what they already repay each month. Work out your real position with our budget planner before applying.

What does a renovation loan actually cost?

Here is a sample comparison that can help you understand the trade-offs, based on an $80,000 renovation across different options.

What the same $80,000 renovation costs under different finance

Finance type Rate (illustrative) Term Monthly repayment (approx.) Total interest (approx.)
Home loan top-up 6.00% 25 years remaining ~$515 ~$74,500
Home loan top-up (accelerated) 6.00% 10 years ~$890 ~$26,600
Personal loan 10.00% 5 years ~$1,700 ~$22,000
Personal loan 10.00% 7 years ~$1,330 ~$31,500

Figures are illustrative only, as of September 2026, and exclude fees. Based on an $80,000 renovation, principal and interest. The 10% personal loan rate is an assumption for this example only.

The top-up looks lowest at about $515 a month. But over 25 years you pay roughly $74,500 in interest. A personal loan at 10% over five years costs about $1,700 a month, yet total interest is only about $22,000.

The lowest rate does not mean the lowest cost. If you can handle higher repayments, a shorter term reduces total interest, as the table shows. If you cannot, a top-up with a deliberate extra-repayment plan (the accelerated row) closes much of the gap. A broker shows you both numbers, so you decide with your eyes open.

Which option is right for your project?

Start with the renovation scope, not the loan product.

Matching a renovation to the right finance

Project and budget (approximate guide only) Equity? Typical path
Cosmetic under $30,000 Yes Redraw or top-up
Cosmetic under $30,000 No Personal loan
Mid-size $30,000 to $100,000 Yes Top-up or refinance
Mid-size $30,000 to $100,000 No Personal loan, or options through a broker
Structural $100,000+ Yes Construction loan
Structural $100,000+ No Construction loan (based on estimated completed value)
Energy upgrade (solar, batteries) Either Green loan, or add to existing finance

If your situation does not fit a single row, that is what a broker is for.

What do you need to apply?

  • Top-up or refinance: proof of income, current loan statements, a valuation (the lender arranges it), renovation quotes and ID.
  • Construction loan: the above plus a fixed-price contract with a licensed builder, council approval (DA or CDC), detailed plans and builder's insurance.
  • Personal loan: proof of income, ID, about 90 days of bank statements and an estimated project cost.

Get your renovation quotes first. A clear number makes the application cleaner and shows the lender what the money is for.

How does a broker compare renovation loan options?

A bank can only show its own products. A broker can compare a panel of lenders and help match a suitable structure to your renovation.

At Noma Finance, we start with your scope and budget, check your borrowing capacity and usable equity across lenders, then compare rate, fees, total cost and monthly repayment. You can review the estimated costs before you sign. In many cases, the broker is paid by the lender, although other fees or charges may still apply depending on the loan. You can see the full range of what we help with on our services page.

Frequently asked questions

Can I get a renovation loan with no equity?

Yes. A personal loan lets you borrow without property security, with limits that vary by lender. Rates are often higher, but approval is usually sooner, and no valuation is needed. For larger projects, a construction loan may assess the estimated value once the work is complete instead.

Is it better to use a personal loan or home equity?

Home equity is often priced lower but extends your mortgage. A personal loan often costs more per dollar, yet is repaid in five to seven years, so total interest can be comparable on smaller amounts. Compare both the monthly repayment and the total cost.

How much does a home renovation cost in Australia?

Renovation costs vary significantly by scope, location and finish level. A bathroom, kitchen or extension can each cost very different amounts depending on the work involved. Budget an extra 10% to 20% for surprises, and get at least three written quotes.

What interest rate can I expect in 2026?

Home loan top-ups are often priced lower than unsecured borrowing, depending on the lender and your circumstances. Personal loan rates vary widely depending on the lender and your circumstances, and are often higher than secured borrowing. Our guide on how interest rates work in Australia explains what shapes the rate you are offered.

Do I need council approval?

Not for the loan, but sometimes for the work. Cosmetic renovations generally do not need council approval. Structural changes generally need a DA or CDC, and construction lenders may require evidence of approval before releasing funds.

Can a finance broker help?

Yes. A broker compares multiple lenders, matches the structure to your renovation scope, and shows the estimated total cost before you sign. In many cases, the broker is paid by the lender, although fees or charges may still apply depending on the loan.
