A conservatory is more than an extra living space, helping blur the lines between the home and the outdoors. It is a luxury addition to a property and as such conservatory costs typically reflect this.

So how much does a conservatory cost? This article will seek to answer this question by breaking down the cost of a conservatory based on the many factors involved, including size, roofing styles, glazing options, era – and more.

Conservatory Costs via Style

Some conservatories come with an overall style that encompasses the entire room. Each style has its own architectural differences which impact on conservatory prices:

Edwardian Conservatory – An Edwardian conservatory exudes timeless elegance. An Edwardian conservatory is characterised by its rectangular/square overall shape, as well as a pitched roof, which is reflective of the architectural trends of 1901-1910. 

These classical design principles require skilled craftsmanship to replicate accurately, as an Edwardian conservatory places great emphasis on precise symmetry and proportion. The placement of windows or the alignment of roof ridges must adhere to these strict standards. 

Furthermore, craftsmen put great effort into small details, such as creating ornate decorative ridges with rafters, beams and trusses. Elegant finishing touches further strengthen the period piece with the additional features of decorative mouldings, cornices and finials.

Cost of Edwardian Conservatories – Edwardian conservatories may cost between £10,000 and £25,000 depending on the size and additional features. Nonetheless, you can expect the following when factoring in purely size and style.

Size Price Range Notes on Edwardian Features
Small £10,000 – £16,000 Simple rectangular floorplan, classic pitched roof (potentially with subtle decorative cresting), standard uPVC or timber frames
Medium £16,000 – £22,000 Larger rectangular or square floorplan, more elaborate roof cresting possible, potential for coloured glass or stained glass in windows, higher-end frame materials
Large £22,000 – £28,000+ Generous square or rectangular floorplan, potential for roof lanterns or ornate finials, premium materials (e.g., hardwood frames), potential for dwarf walls with decorative brickwork.

Victorian Conservatory – Victorian conservatories draw inspiration from the popular architectural trends during Queen Victoria’s reign (1837 – 1901). They feature intricate roof designs, decorative finials and elaborate crestings, aiming to reflect the populace and grandeur of the era. 

Traditionally, craftsmen working in Victorian conservatories had to possess skills in carving, moulding and casting to apply the intricate details. It’s not uncommon to see bespoke joinery work too, including fretwork and scrollwork created by expert woodworkers. Furthermore, glass contributes to the cost of a conservatory, and a portion of people who opt for a Victorian conservatory wish to also replicate the stained glass artistry of the era.

Cost of Victorian Conservatories – Your Victorian conservatory project will generally cost you more than the other styles of similar size, between £15,000 and £30,000.

Size Price Range Notes on Victorian Features
Small £15,000 – £20,000 Typically 3-faceted bay front, steeply pitched roof, potential for basic cresting and finials, uPVC or timber frames
Medium £20,000 – £26,000 5-faceted bay front, more elaborate roofline, ornate cresting and finials possible, higher-grade materials used
Large £26,000 – £30,000+ Expansive with 5 or more facets, potential for multi-pitched roof or conservatory ‘wings’, premium materials like hardwood, intricate decorative features

Lean To Conservatory – A lean-to conservatory boasts a minimalistic agricultural style that is ironically considered more contemporary and modern than the other styles. They feature a simple, sloping roof design that extends from your property over the extra space seamlessly. 

Its minimalism reduces the overall amount of materials and specialist labour costs. A lean-to conservatory uses UPVC frames and standard glazed windows and is considered a much easier construction job than the traditional conservatories.

Cost of lean-to conservatories – You can estimate the installation costs of lean-to conservatories much easier than you can others, with the range being in the region of £8,000 to £20,000.

Size Price Range Notes on Lean-to Features
Small £8,000 – £12,000 Ideal for limited spaces, simple single-slope roof, standard materials (uPVC or aluminium)
Medium £12,000 – £16,000 More spacious, potential for upgraded roof material (glass), higher-grade frame materials (timber)
Large £16,000 – £20,000+ Suitable for larger extensions, possible inclusion of dwarf walls, potential for solid roof options or roof lanterns

 

Cost of a Conservatory Roof

Outside of all-in-one design philosophies, like the styles outlined above, are individual choices for a conservatory which make a difference to the overall conservatory cost. Roofs are a key feature for conservatories, as since so much of a conservatory is usually glass – they can be subject to temperature fluctuations. The following roofs play an important role in determining the level of light and insulation as conservatory has..

Glass Roof

A glass roof on a conservatory encapsulates what they do best – blur the lines between the indoors and outdoors. With a glass roof, your conservatory will have a bright and open atmosphere due to the expanded transparency, and you’ll have a fully uninterrupted view of the natural landscape around you. That being said, glass conservatory roofs are generally more expensive than polycarbonate roof types.

Tiled Roof

A solid tiled roof is considered modern as far as conservatories go and is a top choice for a conservatory roof replacement project. They provide top-quality insulation and are very durable. They are ideal to be used year-round, ensuring that temperature levels within the conservatory are stable. A tiled roof is also a top choice for traditional conservatories, being reminiscent of classic architectural styles. Putting a tiled roof on a conservatory is usually more expensive than a similar sized glazed conservatory roof.

Polycarbonate Roof

A polycarbonate roof is an option that can reduce your conservatory cost, making it a good option for those with a limited budget. It  is cost-effective yet still provides good insulation and durability. These roofs are very versatile in terms of style, with ranges of light transparency and privacy being features. Polycarbonate roofs can quire frequent cleaning to maintain their appearance, which can add to your maintenance costs.

Additional Conservatory Cost Concerns

There are other concerns to take into account when building a conservatory, and costs will very much be impacted by the size of the conservatory.

Materials

There are several materials to choose from that can make up a conservatory’s structure and these impact on overall cost.

Aluminium Conservatory – Aluminium is a strong metal, allowing being able to bear a minimal frame width and maximal glass coverage. Furthermore, it’s less prone to expansion and contraction with temperature changes, making it a stable choice. The cost of an aluminium conservatory is generally higher than UPVC.

Timber Conservatory – A timber conservatory provides a classic and warm look. It’s chosen often for its natural beauty that adds character to a home, particularly popular in traditional or period-style conservatories. A timber conservatory can vary in price based on the actual type of wood used, as well as the intricacies of the design and finishes that are commonly applied to wood structures for protection.

UPVC Conservatory – The trusty material of UPVC brings high thermal resistance to the conservatory, keeping it warm in winter and cool in summer. It requires little in the way of maintenance and resists discolouration and other weathering issues – meaning it doesn’t need repainting or staining. Best of all – it’s very cost-effective. A UPVC conservatory will flatten the overall cost of a conservatory considerably, making it the preferred option for those with a limited budget.

Planning Permission and Building Regulations

Understand that part of the conservatory cost will come from compliance with legislation that is related to building.

Planning Permission

Planning permission can actually affect conservatory costs. If your conservatory exceeds certain dimensions, or if your property is listed in a conservation area, you will need to apply for planning permission.

The cost of applying for planning permission can vary. In the UK, a planning application is typically around £200.

Building Regulations

Conservatories are exempt from building regulations in the UK so long as they are at ground level, smaller than 30 square metres in floor area, and separated from the house with external walls, doors or windows. If there are new structural openings, however, then building regulations will apply.

This isn’t a flat fee, but rather a series of checks to ensure that the conservatory is energy efficient. We would recommend making your conservatory as energy efficient as possible regardless through the use of double-glazed windows, or low e-glass. Insulation standards are not just there to reduce the carbon footprint but to ensure your dream conservatory is comfortable.

Underfloor Heating

Underfloor heating is an increasingly popular method of providing consistent and evenly distributed heat to a conservatory. Due to the floor being one of the only spaces within the conservatory that doesn’t open out into natural light, it is an effective area to place your heating source.

Installation costs range from £75-£100 per square metre. The running costs of underfloor heating can be high, but in a conservatory with good energy efficiency, it’s easier to manage heat.

Conclusion

Overall, how much a conservatory costs will be dependent on the size, style, materials and other additional options you go for. If you are limited in how much you are able to spend on a new conservatory, then UPVC is the most budget-friendly option. If you are considering replacing your existing conservatory roof, polycarbonate roofing is a cost effective option.

For those looking for something more high end and luxurious, there are plenty of options. It is worth bearing in mind that whatever conservatory type you opt for, it is likely to be a more cost-effective option than a traditional extension, and will still add value to your home. 

FAQ: How much is the average price of a conservatory?

Conservatory costs are made up of a lot of variables, but on average, conservatories in the UK during 2024 tend to be bought for around £12,300 to £14,750.

FAQ: Is a conservatory cheaper than an extension?

Most conservatories are going to be cheaper than a house extension. This is because an extension requires in-depth alterations to existing structures, as well as a lot of brick and mortar. When considering that a conservatory can be built for less than £15,000, a rear house extension can cost between £30,000 to £140,000 depending on size or complexity. Considering you could have two full conservatory installation jobs for the price of the cheapest house extension service on the market, you can see that it’s far more accessible to go with conservatories.

FAQ: Does a conservatory add value to a house?

Yes, indeed. A conservatory adds more space to a home, which is one of the biggest determiners in the cost of said home. As a result, increased living space as home improvements bring great value to the property. Aesthetics is another determining factor, increasing visual appeal and curbside attractiveness.

How much value a conservatory gives is the question, however. A construction based on quality materials will be seen as longer-lasting. Energy efficiency is one the biggest determiners, however, as poor energy efficiency could render the conservatory more of a burden than an asset. Nonetheless, conservatories have been known to increase a home’s value by up to 7%.

FAQ: How much does it cost to take down a conservatory?

The cost of taking down a conservatory depends on how big the conservatory is, and what it’s made of. A uPVC conservatory is quite easy to take down, for example, than hardwood or bespoke structures. Furthermore, complex roof designs and integrated features such as underfloor heating can cause significant slowdowns in the project on top of costs. Disposal of things such as glass, frames, and the base foundations will require waste management services, such as a skip.

FAQ: Do you need foundations for a conservatory?

You will want a foundation every time. UK’s building regulations dictate that conservatories that are treated like extensions to the home. Nonetheless, detached structures don’t need foundations, but we highly recommend you build them anyway.

Foundations provide a solid basis for a structure and ensure that it doesn’t shift or sink over time. The weight of materials like glass and the potential stresses from weather and ground movement would alter the conservatory otherwise.

Furthermore, well-constructed conservatories tend to prevent problems such as cracking, leaking, structural instability etc.
