TV Wall Mounting: Do You Need an Electrician?

How much does TV wall mounting cost in Sydney, and does it need an electrician? A straight bracket mount with no power or cable changes is a simple job, but almost every real wall mount also needs a power point moved or added behind the screen, which is licensed electrical work in New South Wales. Budget roughly $250 to $450 for a basic point relocation on its own, more if wall cavities, brick or concealed cabling are involved.

⚡ Quick Answers: TV Wall Mounting Power and Safety

• Can I mount a TV on the wall myself? The bracket and TV can be a DIY job if you own the tools and the wall type suits it, but any new or moved power point, or any work behind a plasterboard cavity near existing wiring, must be done by a licensed electrician.
• Why do I need an electrician just to hide the cables? A genuinely tidy "floating" look needs a power point installed inside the wall cavity behind the TV, which means running new cable and fitting a point safely clear of studs, insulation and any existing circuits.
• Is it legal to just run an extension cord up the wall? It is not compliant to permanently conceal a flexible cord inside a wall cavity. AS/NZS 3000 requires fixed wiring methods for cable run inside walls, not a household extension lead.
• What does a recessed power point behind a TV involve? A low profile in wall power point and HDMI pass through plate, fed by new fixed wiring back to the switchboard circuit, installed through a small cavity opening rather than a visible external cord.
• Does brick or concrete change the job? Yes. Solid masonry generally means surface conduit or a chased channel rather than a simple cavity run, which adds time and cost compared with a standard plasterboard wall.
• Who do I call for a safe, tidy TV wall mount? High Demand Electrical installs the power point and cable management behind the mount so the finished wall looks clean and is fully compliant.

1. Why the bracket is the easy part

Fixing a bracket to studs or masonry is mostly a mounting and weight rating exercise, and plenty of competent home handypeople manage it safely. The part that usually goes wrong, or gets left as an ugly cord running down the wall, is the power. Wall mounted TVs sit well above the skirting board, but the nearest power point is almost always down near the floor, which is exactly why a dangling extension lead is the default outcome of a DIY mount.

A proper finish means getting power up to the TV's actual height, not routing a cord along the wall or behind furniture. That is an electrical job, not a mounting job, and it is the step most online TV bracket guides skip entirely.

2. What counts as licensed electrical work here

Under the Service and Installation Rules of NSW and AS/NZS 3000, any new power point, any extension of fixed wiring, and any work that opens up a wall cavity around existing circuits must be carried out by a licensed electrician. This applies whether the new point sits beside the TV on the surface or is fully recessed inside the cavity. A DIY TV mount that stops at the bracket and leaves the electrical work to a licensed electrician is a sensible, compliant split of the job.

It also matters for insurance. A fire or damage claim connected to unlicensed electrical work behind a wall can be refused, which turns a modest saving on the day into a much bigger risk later.

3. The three common wiring options

Most TV wall mounts use one of three approaches. The simplest is a new surface mounted power point installed directly behind where the TV will sit, with a short visible cord hidden by the TV itself once mounted; this is the cheapest option and works well when the existing point is close by. The second is a recessed in wall power point and HDMI plate, where the electrician cuts a small access point in the plasterboard, runs new cable inside the cavity, and fits a low profile point and signal plate so no cord is visible at all behind the screen.

The third is extending or relocating an existing point rather than adding a brand new circuit, which can be the most cost effective option in an older home with a nearby point and some spare cable length. Which option suits a given room depends on the wall type, where the nearest existing circuit sits, and how invisible the finish needs to be. Our guide to recessed power points covers the fully concealed option in more detail, and our power point installation cost guide gives a general sense of pricing for a standard relocation.

4. Working around studs, insulation and existing cables

Plasterboard walls hide timber or steel studs, insulation batts, and sometimes existing wiring or plumbing, none of which are visible from the front. An electrician uses a stud finder and cable detector before cutting any cavity opening, and plans the cable run to avoid studs and existing services rather than guessing. This is also why a confident DIY attempt at a recessed power point can go wrong quickly, since a blind cut into a cavity risks nicking an existing cable or pipe.

In a brick veneer or solid masonry home, the approach changes again. Chasing a channel into brick for concealed cable is possible but adds real labour, and a surface mounted conduit finished in a matching colour is often the more practical, still tidy solution.

5. Matching the point to the room's actual circuit

A new power point has to connect back to an existing circuit with enough spare capacity, not just the nearest visible cable. Loading up a lighting circuit or an already busy general power circuit with a TV, soundbar, games console and streaming box can trip breakers or create a genuinely overloaded circuit over time. Our guide to how many power points can safely share one circuit explains how this is worked out in practice. An electrician checks which circuit the new point will sit on and whether it has room for the extra load before committing to a cable run.

This is a bigger consideration in a media or entertainment wall with a TV, soundbar, gaming console and a smart home hub all drawing from the same area. Where a lounge room is being set up with several new points at once, it is often worth asking about a switchboard upgrade or dedicated circuit rather than daisy chaining everything off one existing point.

6. Smart TVs, soundbars and the hidden power point count

A modern entertainment setup rarely means just the television. Soundbars, subwoofers, streaming boxes, games consoles and smart speakers each want their own power point, and most wall mount jobs end up needing two to four outlets in a space that started with one. Planning for this upfront, rather than adding points one at a time over following months, means one cavity opening and one cable run instead of several separate call outs.

A double or quad power point recessed behind the TV, with a separate HDMI and data pass through plate, covers most modern setups in a single clean installation and avoids a visible power board sitting on the floor beneath the unit.

7. Older homes and outdated wiring behind the wall

Homes built before the 1980s sometimes still carry older wiring types, including original circuits that were never updated when the rest of the house was renovated. Opening a cavity for a new TV point in one of these homes is a good moment to check what is actually behind the plasterboard, since an electrician doing the cavity work will usually flag any wiring that looks aged, undersized or unsafe while the wall is already open.

This is particularly relevant in Sydney's older suburbs, where federation and post war homes often have a mix of original and later wiring. Catching an issue during a TV mount is far cheaper than finding it later during a full rewire.

8. Planning ahead for a full home theatre or media wall

A single TV point today often becomes a full media wall later, with additional points for a projector, a gaming setup, networking equipment or a home automation panel. Where a bigger media room or home theatre is on the longer term plan, it is worth having the electrician rough in extra capacity or conduit while the wall is open, rather than repeating the cavity work from scratch for every future addition.

Our sister site HD Inner West covers this kind of forward planning in more detail in its guide to power point planning for a renovation, aimed at anyone tackling a larger room refresh rather than a single TV mount.

Why it's licensed electrical work

Any new or relocated power point, and any work that opens a wall cavity around existing circuits, is electrical work under AS/NZS 3000 and must be carried out by a licensed electrician, not left to a general handyman or a DIY attempt. Our Level 2 electrician page covers the wider range of accredited work we carry out, and for a straightforward TV point this is standard licensed electrical contracting rather than Level 2 network work.

TV Wall Mounting FAQs (Sydney)

Can I just run a power board up the wall instead of a new point?

You can use a power board plugged into an existing point, but a visible cord and power board running up the wall defeats the clean look most people want from a wall mounted TV, and a cord permanently taped or concealed inside a wall cavity is not a compliant fixed wiring solution.

How much does a recessed TV power point cost?

A recessed in wall power point and HDMI plate typically costs more than a simple surface mounted point because of the cavity work involved, though the exact price depends on wall type and cable run length. A site visit lets us quote accurately rather than guessing from a photo.

Will opening the wall damage my plasterboard?

A professional cavity opening is a small, clean cut sized to the power point plate, and the plate itself covers the opening once installed, so there is no visible damage once the job is finished.

Can I add a power point behind a TV in a rental property?

Any permanent electrical work needs the landlord's approval, and a licensed electrician will still need to carry out the work itself. Speak with your property manager before booking the job.
