So one of the main questions we are asked is how much does it cost to get that sucker up on the wall? and the answer is it depends on the size of the TV. Usual any television up to 50 inches” has a rough price rate of around £69 and £120. TVs between 55” to 80” cost between £139 and £199 to mount, and over 81” costs around £240 as it will need 2 men.
