Getting the order of trades right can make or break your Brisbane home improvements. When you are mixing switchboard upgrades, solar, EV chargers and new air conditioning, timing is everything. The wrong sequence can mean walls opened twice, extra days without power, and a lot of stress for the household.

What many people do not see at first is how tightly linked these jobs are. If the switchboard is not ready when the solar team arrives, they may have to come back. If the EV charger is added after plastering, you may be cutting fresh paint to run cables. Every extra visit means more time, more mess and more risk of delays for the rest of the build.

This is where having a master electrician who thinks like a project manager really helps. We can coordinate with your builder, solar installer, air conditioning techs and EV charger specialists so the right work happens at the right time. At Heat On Electrical, we have spent decades on complex renovations across Brisbane, and we know that good planning protects safety, your budget and your schedule.

Start with the Switchboard and Safety Foundations

The switchboard is the heart of your electrical system. Before you worry about panels on the roof or an EV in the driveway, you need to know your mains and switchboard can actually support the extra load and meet current Queensland standards.

Common triggers for a switchboard upgrade during home improvements are:

• Adding new power circuits or lighting for extensions or kitchens 

• Installing larger air conditioning systems that may need three-phase supply 

• Planning an EV charger that will draw high current for long periods 

• Replacing old ceramic fuses with modern safety switches and RCDs 

Doing the switchboard work early sets the foundation for everything that follows. It allows us to check supply capacity for solar, EV and extra AC, bring protection devices up to current requirements, create space and clear labelling for future circuits, and plan for possible three-phase power if your home needs it.

Timing matters here because it affects every other trade that connects to power. Often, we will assess the mains and switchboard at the planning stage, then carry out the main upgrade around demolition and rough-in, while keeping outages as short as possible by planning changeovers carefully.

A Gold Master Electrician will also set up the board so later trades can connect cleanly. That means enough ways for future circuits, room for solar and battery gear, and sensible grouping of loads. With a future-proof layout, you avoid having to reopen walls or rework the switchboard when you add that second AC or a future EV.

Timing Solar Installation Around Roof and Electrical Works

Solar does not live in a bubble. It sits on your roof, ties into your switchboard and often shares scaffolding or access with other trades. The smartest way to plan it is alongside roofing and structural work.

A good sequence usually looks like this:

• Finish any major roof repairs or re-roofing before panels go on 

• Rough-in solar cabling and isolator positions during electrical rough-in 

• Complete the switchboard upgrade before the solar system is commissioned 

If insulation upgrades or roof extensions are part of your renovation, it is best to finish those first so panels do not have to be removed later. During rough-in, we can run solar cabling and plan safe isolator locations while also allowing for future changes such as battery storage space, extra capacity for a larger solar array, and clear, tidy connections at the upgraded switchboard.

In Brisbane, many people like to have solar running before peak summer air conditioning use, to offset those higher power bills. Spring can be a handy window, with more daylight hours and generally workable weather. When we coordinate with your chosen solar installer, we can often:

• Share scaffolding or access equipment 

• Align site visits to cut down on interruptions 

• Make sure inspections and meter work are booked in the right order 

Integrating EV Charger and Air-Con Without Double Handling

EV chargers and air conditioning both place strong, steady demands on your electrical system. If we do not plan them together, you can end up with nuisance tripping, an overloaded supply, or a switchboard that needs another upgrade later.

Load calculations are key. Before we run any cable, we look at:

• Existing household loads such as ovens, hot water and pool pumps 

• Planned EV charger type and likely charge times 

• Number and size of AC units, especially if they may run at the same time 

From there, the best way to avoid rework is to align cabling, locations and fit-off with the build stages. The best sequence to avoid double handling is:

• Rough-in dedicated EV and AC circuits while walls and ceilings are open 

• Plan exact locations for EV charger, indoor AC heads and outdoor units 

• Leave final fit-off until after plastering and painting are complete 

For EV chargers, we also think through practicalities that are much easier to solve early, including:

• The best path from the meter box to the parking area 

• Space for a second charger if another EV is added later 

• Safe mounting heights and clearances around the unit 

For air conditioning, planning is not just electrical, it affects comfort, noise and long-term serviceability. We look at:

• Outdoor unit placement away from bedrooms and neighbours where possible 

• Airflow around the unit so it can run efficiently 

• Access for future servicing and cleaning 

A coordinated plan means you can stage your home improvements without paying twice. Even if you only install one split system or no EV charger at first, the wiring and board space can be set up now. Then, when you add more later, it is a simple fit-off, not another major electrical job.

Scheduling to Minimise Downtime and Trades Clashes

Good timing keeps your home liveable during a renovation, especially if you are working from home or have kids at school. A simple, typical sequence for a Brisbane renovation might be:

• Demolition and structural changes 

• Electrical inspection, switchboard works and rough-in 

• Framing adjustments and any roof works 

• Solar install and connection once the roof is ready 

• Plastering, sanding and painting 

• EV charger and AC final fit-off 

• Final testing, labelling and handover 

To keep this moving smoothly, communication between trades matters just as much as the order of tasks. We suggest:

• Weekly check-ins between key trades 

• A shared schedule that flags when electrical access is needed 

• Clear no-go dates where power must stay on for family or business needs 

We also plan around inspections and supply authority requirements so critical approvals do not create a bottleneck later. In practice, that means:

• Meter changes are booked in line with switchboard works 

• Solar approvals and connection do not hold up other trades 

• Temporary supply options are considered if needed 

Experienced electricians are used to busy periods, like the rush before summer or before school holidays. Planning early means better chances of locking in time with AC techs, solar installers and other key trades when you need them most.

Lock in Your Electrical Game Plan Before You Start

The best time to think about your electrical needs is before a single wall comes down. A bit of planning upfront can save a lot of mess later.

When you sit down to plan your home improvements, make a full wish list that covers:

• Solar power and possible future batteries 

• One or more EVs, even if they are a few years away 

• Pool equipment, spas or outdoor showers 

• Outdoor kitchens, lighting and power points 

• Security cameras, intercoms and smart doorbells 

• NBN location and data cabling through the house 

At Heat On Electrical, we like to start with a pre-renovation electrical planning session and a thorough switchboard assessment. From there, we can map out a staged plan that fits your renovation schedule, keeps your switchboard safe and ready, and lines up the timing of solar, EV charger and air conditioning installs so they are each done once and done properly.
