Best Post Level 

Thanks for taking your time to read our reviews on the best post level that are currently available on the United Kingdom marketplace.

A post level is used to help erect straight posts for fences, for posts on a deck or to help align ceiling joists for rafters.

It is a form of a spirit level that finds both the level and the plumb when setting up a post. The level is made from plastic and is two-sided that forms a 90° angle.

Most of them have three vials, and the vial is the small glass part with the bubble inside. Having those makes sure the post is vertically aligned, and also aligned horizontally in either direction.

This is such a nice, simple and handy tool to use and it makes the job so much easier.

Just below you will see our top 5 list of post levels. However, we also know you are busy, so if you don't have time to read our full review, we would highly recommend the Silverline SL05 Post Level, 140 x 100mm

Post Level Buying Tips

This is another really simple and yet brilliant tool. These levels work really well and there's not that many different features to consider or differences between the models.

You will want your post level to have some kind of magnet to attach it to a metal post and if its a wooden or concrete post then you will need some way to attach to that. This usually comes in the form of a strap and some of them are elasticated or could be rubber. Best to have both methods as you could be working with different types of posts.

To find the level on 3 axis then you will obviously need three vials. Two is no use to you, though all the ones I have seen have the three.

Waterproof, hard wearing, non-rusting all point to making this tool ideal to be made in toughened plastic, so that's the only type of construction you should be looking for.

Some of the models fold and I found this quite handy but its not a deal breaker. I actually use a laser level for these types of jobs and some of them are not that expensive if you only need to use it for the odd job.
