Is There A Standard Size For A Loft Hatch?

If you are looking to replace your loft hatch or perhaps want to install a loft ladder then you’ll need to take measurements to ensure you buy materials of the correct size. Most homeowners wonder if there is a standard loft hatch size. 

While there is a standard loft hatch size, you’ll find that there is a lot of variation. Moreover, there are no standards set by Building Regulations so you can never guarantee that the hatch will be a minimum size. 

In order to help you figure out exactly what you need, I’ve put together this short guide on loft hatch sizes.

What Is The Standard Size For A Loft Hatch UK?

In the UK, Building Regulations dictate that certain features must meet specific standards but this does not apply to loft hatches. That said, the Building Regulations do advise that loft hatches should be at least 530 mm x 530 mm but this is certainly not something that must be adhered to. 

The standard loft hatch size in the UK tends to be around 562 mm x 726 mm. However, it is not uncommon to also find them in the following sizes:

  • 450 mm x 600 mm
  • 600 mm x 700 mm
  • 700 mm x 900 mm

Is It Easy To Install A Loft Hatch?

Whether you are looking to replace your existing loft hatch door or wish to build a permanent loft ladder then the good news is that this can be undertaken as a DIY job. Of course, you will need to have some basic DIY skills and the right tools for the job so make sure you’re prepared before you take on any work. 

One of the first things you’ll need to consider is the size of the loft hatch and source a hatch door and frame that is going to fit. The great thing is that there are a multitude of colours and materials to choose from so you can get something that’ll blend into the decor of your home; or stand out if you want to make a statement!

If you are at all unsure about installing a new loft hatch or ladder then I would recommend calling in the pros. This will ensure the highest quality and best standard of work. 

Do I Need To Install A Loft Ladder?

One of the main reasons that people are interested in finding out the standard dimensions of a loft hatch is because they are considering installing a loft ladder. 

Now, you first have to think about whether there’s really a need for a loft ladder. If you have a standard sized hatch then you’ll only really have one option and that’s a traditional loft ladder that’s placed into the frame of the hatch. This is a good solution for people who don’t use their lofts very often. For example, if you only go up there once a year to get the Christmas tree down. 

But if you need to gain access to the loft more frequently then having to move a traditional loft ladder back and forth can be a bit of a pain. In these situations, it might be best to install a built in loft ladder and this will require you taking measurements to ensure the ladder you choose is compatible with your loft. 

I Have A Plastic Loft Hatch; Is This Fire Resistant?

Plastic loft hatches are affordable and easy to install. However, while they are a popular choice, you have to keep in mind that they are not fire resistant. This means that, should a fire break out in the loft, the plastic hatch will not prevent it from spreading to other parts of the building. 

You can purchase fire resistant loft hatches that are made from steel and are insulated. They come in a range of sizes and usually offer around one hour of resistance. 

Final Thoughts

While there is not a standard size for loft hatches in the United Kingdom, most will measure 562 mm x 726 mm. Building Regulations suggests at least a 530 mm x 530 mm loft hatch but this is not a rule that has to be followed.

When measuring for a loft ladder or replacement hatch door, you should not simply assume that your hatch will be within the most common sizes. Always take measurements to ensure the greatest accuracy.
