Best Heavy Duty Wall Fixings for EV Chargers & Heavy Loads: 2025 Expert Review
Oli at OR Electrics
18th Edition Fully Qualified Electrician
Whether you are mounting a heavy consumer unit, securing conduit, or installing an EV charger, the choice of wall fixing is critical. In Leeds, we deal with a mix of solid brick back-to-backs and modern timber-framed homes with plasterboard partitions. Getting the wrong fixing isn't just annoying; strictly speaking, it can be dangerous.
An EV charger, in particular, endures 'dynamic loading'—every time you pull that stiff charging cable, you are exerting force on the wall fixings. Standard plastic plugs often wiggle loose over time, leading to unsafe electrical connections.
In this review, I'll walk you through three fixing solutions I keep in the van: a solid assortment for traditional brickwork, a high-load specialist for standard plasterboard, and a problem-solver for tricky insulated walls.

Specs vs. The Real World
The Spec: "Universal Fixings"
"Marketing suggests one plug works perfectly in brick, block, and plasterboard."
There is no true 'universal' fixing for heavy electrical loads. What holds tight in solid brick often spins uselessly in plasterboard. Always match the fixing to the substrate.
The Spec: "Load Ratings (Static vs. Dynamic)"
"A fixing is rated for 100kg+."
That rating is for a static weight hanging straight down. An EV charger involves pulling and twisting (dynamic load). I always derate capacity by 50% for safety when cables are involved.
My Top 3 Recommendations
Three options to cover different needs and budgets
All in One Multi Purpose Multi Fix Use Assorted Size Wall Plugs Heavy Duty Raw Rawl Plug Fixings Brick Stone Cement Concrete Hollow Cavity Partition Partitioning Drywall Professional Hanging Clamps Screw Fixing in Different Sizes Pack of 52
PLASPLUGS
Every electrician in Leeds needs a box of these for the solid Victorian brick found in terraces. Whilst they claim to be 'all in one', they truly shine in solid masonry for securing cable clips, lighter distribution boards, and surface-mounted back boxes.
The Good
- Excellent grip in solid brick and stone (common in Leeds)
- Assorted sizes cover everything from cable clips to small fuse spurs
- Anti-rotate ribs prevent spinning in the hole
The Bad
- I do not recommend these for heavy loads on hollow plasterboard
- Requires precise drill hole sizing for maximum grip
Installer Tip:
When drilling into old Leeds red brick, use a masonry bit and clear the dust out of the hole with a vacuum or blower before inserting the plug. This ensures the expanding barrel grips the brick, not the dust.

Bullfix
For mounting EV chargers on garage partition walls or internal plasterboard, this is the gold standard. The unique mechanism opens wings behind the board, distributing the weight effectively so the charger doesn't rip away from the wall.
The Good
- Incredible holding strength on standard plasterboard
- Perfect for Dot & Dab walls (common in modern renovations)
- Includes the necessary 20mm spade bit
The Bad
- Requires a large 20mm hole, which is difficult to patch if you move the unit
- Not cheap, but cheaper than repairing a damaged wall
Installer Tip:
If you are mounting an EV charger backplate, use these fixings. The constant plugging and unplugging creates movement; these anchors resist that movement far better than standard screw-in plasterboard plugs.

Bullfix
Many modern garages or energy-efficient renovations use insulated plasterboard (warm board). Standard fixings aren't long enough to bridge the insulation gap. The 'Extra' range solves this nightmare scenario by bridging the gap to secure firmly behind the board.
The Good
- Solves the specific issue of fixing to insulated plasterboard
- Highest load capacity in the list
- Prevents the fixing from crushing the insulation foam
The Bad
- More expensive per unit
- Overkill for standard single-sheet plasterboard
Installer Tip:
Before purchasing, try to measure the thickness of your plasterboard plus insulation properly. These are designed specifically for that deeper cavity. If you use too short a fixing in insulated board, the charger will eventually pull loose.
