TV wall mounting

A professional installation ensures your expensive screen is securely fastened using the correct anchors for your specific wall type. Beyond safety, a professional can handle complex cable management, ensuring your living room remains free of cluttered wires and unsightly plastic trunking.

What Does the Work Involve?

• Site Survey: Identifying wall construction (stud, brick, or dot-and-dab) and checking for hidden pipes or electrical cables.
• VESA Check: Confirming the TV’s mounting pattern and weight are compatible with the chosen bracket.
• Fixing the Bracket: Drilling and securing the wall plate using heavy-duty anchors (e.g., coach bolts for masonry or specialist toggles for plasterboard).
• The Lift: Attaching the TV to the arms and mounting it onto the wall plate (usually a two-person job for screens over 50 inches).
• Leveling & Securing: Fine-tuning the horizontal level and tightening safety screws to prevent the TV from being knocked off.
• Cable Management: Routing power and HDMI cables through surface-mounted trunking or "chasing" them into the wall for a hidden finish.

Typical Costs

Prices are influenced heavily by your location, with London and the South East typically seeing a 20% premium. The complexity of your wall—specifically if it requires specialist "GripIt" fixings for hollow walls or diamond-tipped bits for porcelain tiles—will also affect the final quote.

How Long Does It Take?

• Standard Masonry Mount: 1 to 1.5 hours.
• Stud Wall Mount (finding timber): 1.5 to 2 hours.
• Internal Cable Routing: 3 to 5 hours (depending on plastering requirements).
• Soundbar Integration: Additional 30 to 45 minutes.

DIY or Professional?

While a basic fixed bracket on a solid brick wall is a manageable DIY task for a confident hobbyist, mounting on modern plasterboard is risky. Standard wall plugs often fail under the "leverage" weight of a TV, especially when using a cantilever arm that extends away from the wall.

Professionals carry high-end sensors to detect hidden services and use industrial-grade fixings that the average DIYer won't have in their toolbox. Furthermore, if you require a new electrical socket installed behind the TV to hide the power lead, this must be performed by a Part P qualified electrician to comply with UK Building Regulations.

Expert Tip: Always check your home insurance policy. Many providers will not cover "accidental damage" if a TV falls off a wall that was DIY-mounted without professional certification.

Choosing the Right Tradesperson

• Check Qualifications: Look for installers who are members of the Confederation of Aerial Industries (CAI) or have AV-specific certifications.
• Insurance: Ensure they hold Public Liability insurance that specifically covers "items being worked upon" (your TV).
• Wall Knowledge: A good pro will ask what your wall is made of before they arrive so they can bring the correct anchors.
• Questions to Ask:
  • "What specific fixings do you use for hollow plasterboard walls?"
  • "Do you use a laser level to ensure the screen is perfectly straight?"
  • "Is a two-person lift included in the price for my large screen?"
  • "Can you provide photos of previous cable-hiding jobs?"

UK Regulations

• Part P (Electrical Safety): Any new electrical circuits or socket extensions in a domestic setting must be installed and tested by a competent person.
• Building Regs: If you are "chasing" cables into a wall, you must ensure you aren't compromising the structural integrity of a load-bearing wall or a fire-rated partition.
• Leasehold Agreements: If you live in a flat, check your lease. Some agreements prohibit drilling into "party walls" (shared walls) without written consent.

Common Problems

• The "TV Too High" Syndrome: Homeowners often want TVs mounted high like a painting, leading to neck strain. The centre of the screen should ideally be at eye level when seated.
• Incompatible Brackets: Buying a cheap "universal" bracket that blocks the TV's HDMI ports or power input.
• Cable Length Issues: Forgetting that cables need an extra 1-2 metres of length to travel down a wall or through an arm, leading to tension and port damage.
• Hidden Obstructions: Hitting a metal "lintel" above a fireplace or a plastic water pipe inside a stud wall.

Frequently Asked Questions

Can you mount a TV on a hollow plasterboard wall?

Yes, but you must use specialist fixings like "GripIts" or "Snaptoggles" which spread the weight behind the board. Alternatively, the installer can locate the wooden studs and screw directly into the timber frame for maximum security.

Can a TV be mounted above a fireplace?

It is possible, but heat can damage the internal components of the TV. You should ensure there is a mantelpiece to deflect heat and check that the viewing angle isn't too high, which can cause discomfort.

What is a VESA size and why does it matter?

VESA is the standard distance (in millimetres) between the four mounting holes on the back of your TV. You must ensure your bracket supports your TV's specific VESA pattern (e.g., 400x400) before purchasing.

How do I hide the cables if I don't want to dig into the wall?

The most common alternative is D-Line trunking. This is a decorative plastic conduit that sits on the surface of the wall and can be painted to match your wall colour, making it much less noticeable.

Will mounting my TV void my warranty?

Generally, no. Most manufacturers provide the mounting holes specifically for this purpose. However, damage caused by a fall due to poor installation or using the wrong screws (too long) would not be covered by the manufacturer.
