Do you need a register plate?register plate

If your wood burner or stove has a flue liner already installed, you don't need a register plate.

However, we do recommend that you use one. They're not just great for finishing wood-burning stove fireplace projects, but they have a lot of other benefits too (which we'll talk about in a bit).

Do you need a register plate for your open fireplace?

What if you've got an open fireplace instead of a wood stove?

Our blog has talked about how it's highly recommended (and sometimes a legal requirement) to use a flue liner with an open fireplace before.

Then what about a register plate?

Register plate in the chimneyIt's not a good idea to use a register plate on an open fireplace. They're for wood burner stoves only.

In place of a chimney cap, you should use something called a chimney gather. This is a metal hood that goes around the chimney cavity and connects to the flue liner. This is like a register plate, but shaped to accommodate the dynamics of a burning open fire.

Closure plates vs. register plates

Here's how closure plates and register plates differ:

Register plates seal the base of a chimney cavity without a flue liner.

Closure plates are used when you have a chimney flue liner.

A register plate keeps smoke, soot, ash, and other combustibles from falling back down (if you're using a stove without a flue liner). A closure plate is mostly a cosmetic addition, but it also helps seal up a chimney's base.

These plates aren't that different in terms of practicality.

In fact, they're very often interchangeable - most people in the chimney and flue industry just call them both 'register plates'. They are basically the same thing - metal plates that sit above wood-burning stoves and seal up the chimney cavity.

Why should you use a chimney register plate?

Our team at always recommends that you use a flue liner with wood stoves.

Register plates aren't just for looks you know, they're also practical. Below are all the practical benefits of a register plate.

Save money by preventing heat loss

If your chimney is a Class 1, even if you use a flue liner or flue pipe, a register plate can prevent further heat loss.

As a physical barrier, a register plate prevents heat from escaping up your chimney. Conversely, it prevents cold air from getting in through your chimney. In essence, the register plate helps to maintain an ideal temperature for your living space, saving you from spending more money on your gas bills.

 Protect your home from debris

If you're familiar with any type of old-style chimney, you already know it's a magnet for debris.

If you want to keep your fireplace and living room clean, install a register plate to prevent leaves, twigs, and bird nest bits from falling down your chimney.

Upgrade the efficiency of your chimney's draw

Your chimney needs to create a strong draw for your stove to perform at its best.

Basically, the air is pushed into the fire and pulled out of the chimney by negative pressure.

Your wood burner or stove's draw will be affected if cool air travels past and beside it and up the chimney. Register plates solve this problem by removing spaces where air can escape, funnelling it into the fire.

Maintain chimney insulation

A register plate can help contain insulation material if you decide to insulate your chimney - especially if it's an older brick-and-mortar chimney.

Vermiculite, for example, can be poured into the gap between your flue liner and the inside walls of your chimney cavity, with a register plate providing a base for the vermiculite.

Buying the right register plate for you

Let's hope we've convinced you of the benefits of a fireplace register plate. But what should you look for when buying one?

Below are our top suggestions for purchasing a register plate.


The first thing you need is a high-quality galvanised steel register plate.

The zinc coating on galvanised steel makes it durable and corrosion-resistant.

There's no reason why your register plates shouldn't be thick enough to withstand falling debris. But you don't want them so heavy that they are hard to install. That would just be a nightmare!

Our register plates are mainly made from galvanised steel that's 1 mm to 1.5 mm thick at, creating that perfect balance of durability and efficiency. Find the plates we have in stock here.

Fixing brackets

A register plate with brackets is the easiest way to fix it in place and ensures that the register plate fits flush with the opening of your chimney cavity.


You don't want any gaps between the edge of the register plate and the inside of the chimney wall for your register plate to work effectively. Measurements are key here.

If your chimney throat is unusually shaped, it's possible to buy register plates that can be cut down to fit. Measure your chimney throat carefully and select the correct size register plate.

Does a plate need to be pre-cut?

If you're looking for a register plate, you can buy ones with pre-cut holes for the stove pipe.

It's possible to buy register plates without pre-cut holes if you're planning on removing your stove and closing up your chimney base someday.

A note from us: make sure the hole in your register plate is the correct diameter for your stove's pipe if you buy one with a pre-cut hole.

Sealing plates

You may also need a sealing plate along with a register plate.

The sealing plate creates a seal where the stove pipe passes through the register plate. It's often used because the pre-cut holes are usually slightly bigger than the stove pipe diameter.
