Can you replace windows in a listed building? While the answer is yes, the process that you have to go through to get them can make many say no. If you live in a listed building, then you’ll be in a traditional space that is likely to have old windows.

Unfortunately, while these designs may suit the classic look of your home, their performance is stuck in the past. Old timber windows can crack, twist and rot in wind and rain, while single-glazed glass weakens and doesn’t offer a lot of insulation. Because of this, your old windows could be losing as much as 10% of your home’s energy.

However, getting replacement windows for listed buildings can be a nightmare. That’s because, as a protected space, you have a lot of limits for what you can do in your home. For any change you’d like to make to a listed building, you have to undergo planning permission.This process can take months and involves plenty of consultations with your neighbours and negotiations with planning authorities. Also, many regulators are restrictive with the replacement windows they allow. Often, they’ll ask you to get a copy of your current window, which leaves you with the same problem.

Recently, though, things have started to change. Modern windows are beginning to faithfully replicate classic designs, to the extent that you could add them to a listed building. You could get a composite window, for example, which has a solid timber core but uses other materials to protect it.

And, with some manufacturers, you have the option of aluminium heritage windows as well. Rather than repairing your window, you can replace it, and save money on maintenance costs and energy bills. And, with Double Glazing On The Web, it’s much easier and less expensive.

The Benefits of Replace Windows In A Listed Building

With replacement windows, you can switch out the old windows in your listed building. In most cases, these are outdated designs, and they might be suffering problems already. For example, windows like these are prone to condensation.

When cold air strikes against single-glazed glass, there isn’t a lot of resistance. Because of this, it can pass into your home quickly, while warmth escapes your home at the same pace. As a result, these different air pressures collide, creating a convection effect that causes heat to rise and a mist to develop on your window. Condensation can turn into a mould as well.

With replacement windows, though, you’ll add air and water-tight design to your listed building. You’ll have the option of composite windows in many cases, which use timber in a way that suits the modern world. Instead of rain and water damaging the wood, layers of uPVC and GRP protect the wood from it.

Both of these materials are fully weatherproof and have no design gaps. As a result, wind and rain won’t affect their strength and shape for decades. These windows are scratch-resistant too, meaning you won’t need to carry out regular maintenance on these windows.

Also, you’ll be able to use far more of your home’s energy. Older windows don’t have a lot of insulation, allowing your home’s heat to escape and cold air to play havoc with your living space. However, you can get replacement windows with double glazing as standard.

That way, you’ll get two layers of protection against the cold, and you’ll reduce heat transfer massively. When you pair that with a durable frame that is made-to-measure for your home, there’ll be no space for energy to escape. That means you can stay warm without your central heating.

With Grade II spaces, planning authorities are more open to minor changes, so long as they don’t spoil the traditional look of the property.

If you want to start the process, then working with a top local company is essential. That way, you can work with a trusted expert throughout, and you can build a more robust case for replacement windows. For example, you could provide CAD drawings of the new design, and produce an expert opinion that your current windows are detrimental to your home.

After you begin the application process, there is also a period where anybody who might have issues with you replacing your windows can lodge their opinion. That means going to consultations where you’ll be able to convince people of your argument.

Also, you’re more likely to be successful if you don’t replace all of your windows. Instead, it’s better to switch out the ones that are most in need of a change. Planning authorities are more likely to agree to a blend of repair and replacement.

Then, the last thing is making sure the windows you’d like suit your home. If you have timber windows, then you can replace them with like-for-like designs without planning permission! However, with some authorities, composite and even aluminium heritage windows can fit the bill.
