Replacement Conservatory: The Ultimate Guide

If your conservatory is damaged beyond repair, outdated or no longer working property, it might be time to replace it. Sometimes, that’s the only solution. Then, you no longer have to worry about heat loss, exorbitant heating bills, condensation and those other annoying problems that usually occur when a conservatory is on its last legs.

This article is about conservatory replacement but we must mention that there are alternative solutions. A replacement conservatory is not your only option. You could also solve these problems with windows or roof replacement alone. In some cases, replacing the frame or glazing alone might be enough. Any of these alternatives will cost less money.

However, they aren’t as effective. They are also not technically conservatory replacement measures. So, let’s stay on topic and leave them to another article dedicated to conservatory refurbishment. For now, let’s talk about the whys, hows, and whats of replacement conservatories.

Complete conservatory replacement

Before deciding to refurbish or replace your conservatory, it’s essential to take into account the size and design that will best suit your needs. Whether it’s due to deterioration, damage, or simply a desire for a modern refresh, many UK conservatory providers offer comprehensive solutions to revamp your existing space.

Conservatory styles come in a diverse range, each with its unique charm:

• The practical Lean-to conservatory
• The elegant Edwardian conservatory
• The classic Victorian conservatory
• The grand Gable-end conservatory
• The versatile T-/P-shaped conservatory

For those with aspirations to expand their living space or embrace a new conservatory design, this often means the original base and foundation must be dismantled and reconstructed to accommodate the new layout and size.

When considering a new base for your conservatory, you have several options:

Traditional Base:

Opting for a traditional base involves laying down a solid foundation of concrete. This task demands precision and is best handled by a seasoned installer. From excavation to setting the concrete, followed by the construction of flooring and brickwork, the process can be extensive, potentially spanning several weeks. But for those looking to integrate underfloor heating, a concrete base is advantageous as it provides uniform heat distribution throughout the conservatory.

Steel Base:

For a quicker and less invasive approach, a steel base is advantageous. The foundation requires shallower digging, which minimises excavation debris and lessens the chance of disturbing any existing underground utilities. Comprising a steel frame supported by beams, it allows for easier access to any below-ground services, offering a balance of efficiency and functionality.

Wooden Base:

If your property is on uneven ground, such as a slope, a wooden base might be your preferred choice. The adaptability of timber allows for an accommodating adjustment to the contours of your land. Construction is generally more straightforward, producing minimal excavation waste. Using bolts to secure the wooden beams and frame, this type of base offers a robust platform for your conservatory.

Each option has its own set of advantages, tailored to different needs and situations, making it possible to select the most suitable and sustainable foundation for your new conservatory.

Replacing an existing conservatory

Opting for a like-for-like conservatory replacement—an exchange where your old conservatory is replaced by a new one of identical style and dimensions—holds several advantages over constructing a completely new conservatory or adding an extension. This approach is generally preferred for its minimal disruption to your daily life, shorter completion time, and cost-effectiveness. 

Moreover, it typically circumvents the need for additional planning permissions, assuming the new conservatory matches the size of the old one. Nevertheless, it’s advisable to secure certification confirming that no extra permissions are required, although standard building regulation approval will still be necessary.

When budget considerations are paramount, a like-for-like conservatory is a sound choice over more extensive renovation projects. Nonetheless, it’s crucial to evaluate the state of your existing conservatory’s base. A base that has deteriorated or lacks the strength to support a new structure may necessitate replacement, which can impact both the timeline and the expense of the project.

To minimise the financial outlay when undertaking a conservatory replacement, it is wise to solicit and compare estimates from various companies. Prices can fluctuate depending on the size of the firm and its geographic proximity to your location. By exploring multiple quotes, you can ensure that you secure a competitive rate that reflects the specificities of your region and the scale of the conservatory provider’s operations.

The cost of conservatory replacement

The cost of replacing a conservatory can vary widely based on a range of factors, such as:

• Size of the conservatory: The larger the structure, the more materials and labour will be required, which increases costs.
• Design and style: A complex design with bespoke features will be more expensive than a standard model.
• Material quality: High-quality materials such as energy-efficient glass, aluminium frames, or durable PVC will cost more than basic materials.
• Type of glass: Special glass types such as self-cleaning, anti-glare, or thermally efficient options will add to the cost.
• Roofing options: Solid roofs are typically more expensive than polycarbonate or glass roofs.
• Foundation work: If new foundations are needed or if the existing ones need to be reinforced, this will increase the price.
• Interior finishes: The cost can increase with higher-end interior finishing, including flooring, blinds, and electrical fittings.
• Location: Costs can vary by region due to differences in labour rates and transportation costs.
• Accessories and extras: Adding features such as underfloor heating, extra doors, or bespoke guttering can increase the total cost.
• Removal of the old conservatory: If you need to dismantle and dispose of an existing structure, this will add to the cost.

The Benefits of a Modern Replacement Conservatory

Once again, a modern replacement conservatory is better in many ways. Here are some of those ways.

Enhanced Aesthetic Appeal

Because it’s new, the replacement conservatory will look more visually appealing than an old or damaged one. However, age is not the only factor in play. It is also about the aesthetic appeal of modern conservatory building materials. Take wood effect uPVC as an example. It wasn’t around back in the day. Now, it is. So, you don’t have to make as much compromise between affordability and aesthetic value. 

Improved Energy Efficiency

A replacement conservatory will use double glazing, triple glazing or highly insulated polycarbonate. Therefore, it is going to be more energy efficient. Your old conservatory, on the other hand, probably has single glazing and inferior polycarbonate. Conservatory tech has come a long way. So, it isn’t surprising that a modern replacement conservatory will be superior in energy efficiency.

Boosted Property Value

Conservatories can increase the value of a property by about 5% to 12%. However, this will depend on the appeal and health of the conservatory. An old and damaged one won’t add anything. It may even decrease the value of a property. In contrast, a modern replacement conservatory will undoubtedly make a property more valuable.

Alternatives to Conservatory Replacement

Earlier in this article, we said refurbishment is an alternative to conservatory replacement. So, let’s talk about it. Here are the two types of conservatory refurbishments.

Conservatory Roof Replacement

If the roof is the only part that is damaged, outdated or not well-insulated, you probably just need a new one. You don’t need a replacement conservatory. However, only try this if the rest of the conservatory is in good condition.

Conservatory Windows and Doors replacement

If the windows and doors are the only things that need replacing, there is no need for a complete conservatory replacement. Sometimes, you just need to change a few panels. However, you should only do these if the remaining parts of the conservatory are still healthy and up to date. If not, a replacement conservatory is your only option.

Conclusion

There is little difference between a complete conservatory replacement and a new installation. So, everything you learned while building the existing conservatory will be helpful during this replacement project. However, even without the advantage of prior experience, this conversation is all the ammunition you need. 

Just remember to make the right choices to create the best possible replacement conservatory within your budget. Some of these “right choices” include picking good conservatory materials and design, hiring a qualified and reputable installer and ensuring your new replacement conservatory meets modern standards and building regulations.

FAQs

Can You Replace a Conservatory With An Orangery?

Yes, these two are similar in many ways. So, the orangery will perform the same way as any replacement conservatory. The installation process is identical, too. However, there are some functional differences between them. Therefore, make sure you really want an orangery, not a conservatory with less glazing.

Do You Need Planning Permission for a Replacement Conservatory?

You don’t need planning permission unless your conservatory breaks the rules of permitted development.
