When it comes to jobs around the house, a huge 79% of Aussie homeowners have blown their budget. And with only 6% getting it right, underestimating costs has left many a home improver scrambling to adjust mid-project.

After 10 years of renovating, here’s what we’ve learned about keeping your budget in check while still creating a home you’ll love.

1. Don’t underestimate the costs

Got a budget number in mind? Great. But have you checked if it aligns with today’s market?

Renovation costs are a moving target, thanks to fluctuating material prices and labour demands. Underestimating costs – especially for fittings, fixtures, and trades – is one of the quickest ways to derail your budget.

Top tips

  • Be honest about your vision – think carefully about how high-end or extensive you want your project to be and balance it with what’s realistic within your budget.
  • Account for labour – labour isn’t cheap and can take up a hefty chunk of your budget. Factor it in early to avoid nasty surprises.
  • Talk to the pros – chat with tradies and builders to get accurate estimates. The more info you have upfront, the better.
  • Compare quotes – don’t settle for the first quote. Shop around but make sure you’re comparing apples with apples.

2. Do have a contingency budget

Surprises? They’re inevitable. That’s why a contingency fund is your best friend.

It’s not for splurging on fancy tapware but for unexpected fixes, like replacing dodgy old pipes or fixing a crumbling sub-floor (yep, been there, done that).

Top tip

  • For small, cosmetic renos, set aside 10% of your total budget. For bigger, more complex projects, aim for a 20% buffer to cover the “just in case” moments.

3. Do prioritise where to splurge and save

Not every part of your reno needs the luxe treatment. Deciding where to spend and where to save is key to getting the best bang for your buck.

Top tip

  • Splurge on key features – in our projects, we usually splurge on benchtops and engineered timber floors because we know they’ll get a workout in busy family homes. Quality materials like these will save you money on repairs or replacements in the long run.
  • Save on decorative items – focus on budget-friendly accents and decor that can easily be updated later.
  • Opt for durable materials – invest in quality where it matters most but don’t be afraid to get savvy with things like flatpack solutions for wardrobes if custom joinery is out of reach.

Checking permits and approvals onsite with the tradie

4. Don’t overlook permits and approvals

Not the most exciting part of your reno, but permits and approvals are essential. Forgetting them can lead to costly fines and delays – no one wants that.

Top tips

  • Check council requirements – permits vary based on location and the type of renovation, so make sure to check with your local council on what is required for your area and how much it will cost.
  • Engage experts – specialist trades like structural engineers or geotechnical experts might be necessary depending on the job. Budget for their services early.
  • Avoid fines – skipping permits can result in fines and even delays in the project, ultimately affecting your budget.

5. Do regularly check your budget

Think of your budget like a baby – it needs constant monitoring. Regular check-ins will keep you on track and help you dodge surprises.

Top tips

  • Update costs as you go – share your updated budget regularly with your builder to ensure you’re on the same page. This helps them manage costs on their end and alert you to any changes or potential savings before decisions are locked in. Regular check-ins will keep surprises to a minimum and help you stay in control of your spending.
  • Avoid impulse changes – while it’s tempting to add extras, avoid spontaneous upgrades that aren’t budgeted. Small splurges can add up quickly and push you off track.

6. Don’t cut corners on quality

Sure, keeping costs down is important, but cutting corners can backfire. Cheap materials and dodgy trades might save money now but could lead to expensive repairs later.

Top tips

  • Create a scope of work – this is a document you’ll use to brief trades on what services you require from them, with specific details to ensure clarity, consistency, and high-quality results across all aspects of the project. It’ll also help you compare when you receive multiple quotes.
  • Invest in trusted tradies – always go for licensed and experienced professionals – it’s worth it to protect your investment.

FAQs

A good rule of thumb is to set aside 10–20% of your total budget as a buffer. This can help cover any unexpected expenses, from material price increases to unforeseen structural issues.

Focus on saving in areas that are easily updated, like paint, styling or some simple landscaping, like laying lush new turf. Consider mid-range options for fittings and fixtures and splurge on high-traffic areas like bathrooms and kitchens.

Regularly monitor your budget, keep track of expenses, and avoid impulsive changes or upgrades. Work with your builder to keep your budget on track by discussing costs upfront and regularly reviewing any changes. Remember, sticking to your plan is the key to avoiding budget blowouts.

Permits ensure your renovation meets local council regulations and safety standards. Costs vary but generally range from a few hundred to a few thousand dollars, depending on your location and the type of renovation.
