If your white UPVC conservatory is starting to look tired, yellowed, or just plain dated, you are not alone. Millions of conservatories were built across the UK between the late 1990s and early 2010s, and the vast majority were finished in standard white UPVC. Twenty years on, many of those conservatories are still structurally sound but look like they belong to a different era.
The good news is that you do not need to replace your conservatory to make it look modern again. Professional UPVC spraying can completely transform the appearance of a conservatory, changing it from a dated white box into something that looks like a purpose-built contemporary extension. It is one of the most dramatic home improvements you can make for the money.
In this guide, I will cover everything you need to know about conservatory spraying: whether it works, what is involved, how much it costs, which colours work best, and what you can realistically expect from the finished result. After more than 11 years of spraying conservatories across the UK, I have seen every shape, size, and condition imaginable, so I will share the practical insights that only come from hands-on experience.
Yes, absolutely. Conservatory spraying uses the same professional 2K polyurethane paint system that we use on windows and doors. The paint bonds chemically to the UPVC surface, creating a durable, weather-resistant finish that is designed to last 10 years or more. We have sprayed conservatories in every part of the UK, from the Scottish coast to the south of England, and the finish performs consistently well in all conditions. If you have broader questions about whether UPVC spraying holds up over time, our guide on does UPVC spraying work covers the science and the real-world evidence in detail.
The reason conservatory spraying is so effective is that the UPVC framework of a conservatory is the same material as your windows and doors. If you can spray a window frame, you can spray a conservatory. The only difference is scale. A conservatory has more framework, more complex angles, and more surface area, which means the project takes longer and requires more skill, but the fundamental process and the end result are the same.
A UPVC conservatory is made up of several different components, and most of them can be sprayed.
All of the UPVC window frames, opening casements, and door frames within the conservatory can be sprayed. These are treated in exactly the same way as standalone UPVC windows elsewhere on the property. The frames are cleaned, degreased, abraded, primed, and sprayed with 2K polyurethane paint.
If your conservatory has a UPVC roof structure, the bars, ridge cap, and hip joints can all be sprayed. This is important because the roof framework is often the most visible part of the conservatory from a distance, and yellowed or chalky roof bars can make the whole structure look neglected. Spraying the roof bars makes a significant difference to the overall appearance.
The external fascia boards, soffit panels, and guttering around the conservatory are usually UPVC and can be sprayed to match the frames. Doing these at the same time as the main framework gives the conservatory a completely cohesive, unified look.
Some conservatories have solid UPVC panels below the windows rather than full-height glazing. These can also be sprayed to match the rest of the structure. The panels are prepared and painted in exactly the same way as the frames.
Glass and polycarbonate roofing panels cannot be sprayed, obviously. Aluminium components, if present, can be sprayed but may require a different primer. Rubber seals and gaskets are masked and protected during the spraying process, not painted. If your conservatory has a tiled or solid roof, the tiles or panels are not sprayed, but any UPVC trim around them can be.
The colour you choose for your conservatory will have a huge impact on how the finished result looks. Here are the most popular options we see.
By far the most popular choice for conservatory spraying, just as it is for windows and doors. Anthracite grey transforms a dated white conservatory into something that looks like a modern aluminium-framed extension. The dark colour hides the framework visually, making the glass appear more prominent and the overall structure look sleeker and more contemporary. It works on virtually every property type.
A softer, warmer grey that is an excellent choice if you find anthracite a little too dark or if your property has a softer palette of colours. Agate grey gives the conservatory a modern update without the dramatic contrast of a very dark frame.
If you are having your house windows sprayed at the same time as the conservatory, matching the colour across both is usually the best approach. It creates a unified, intentional look that ties the conservatory into the rest of the property. Choosing different colours for the conservatory and the house can look disjointed unless the contrast is deliberate and well considered. For a full rundown of popular shades, see our UPVC paint colours guide.
For period properties or homes in conservation areas, softer heritage colours like chartwell green, sage green, or cream can give a conservatory a more traditional feel that sits comfortably with the character of the house. These colours are particularly popular on Victorian-style conservatories and orangeries.
Conservatory spraying costs more than a set of windows because there is simply more surface area to prepare and paint. However, it is still a fraction of the cost of replacing the conservatory entirely.
A small lean-to conservatory with minimal framework typically costs between £600 and £1,000 to spray. A medium-sized Edwardian or Victorian conservatory usually falls between £1,000 and £1,800. Larger P-shaped or wraparound conservatories can be £1,500 to £2,500 or more depending on complexity and access requirements. These prices include full preparation, professional 2K paint, and a 10-year guarantee.
Replacing a conservatory entirely typically costs between £8,000 and £25,000 depending on the size, style, and specification. Even at the top end of spraying costs, you are paying roughly 10 to 15 per cent of the replacement price for a result that makes the existing structure look brand new. The conservatory itself is usually still structurally sound, with years of life left in the frames, glass, and seals. Spraying makes financial sense in the vast majority of cases.
For a full pricing breakdown covering windows, doors, and conservatories, see our UPVC spraying cost guide.
We start with a free site visit to assess the conservatory. We check the condition of the UPVC, the type of roof, access requirements, and any specific challenges. We discuss colour options and provide a clear written quote that covers everything.
On the day of the project, we begin by masking all glass panels, seals, brickwork, paving, and any garden furniture or plants nearby. Every UPVC surface is then thoroughly cleaned with a specialist UPVC cleaner, degreased with a solvent wipe, and lightly abraded to create a key for the paint. An adhesion promoter is applied and allowed to flash off. This preparation stage is the most time-consuming part of the project but it is what makes the finish last. Our UPVC preparation guide explains each step in detail.
We apply the 2K polyurethane paint using professional airless spraying equipment. The paint is applied in thin, even coats, building up the colour gradually for a smooth, consistent finish. Conservatories require careful spray technique because of the complex angles, tight spaces between roof bars, and the need to avoid overspray on glass panels. This is where experience really matters.
Once the final coat has tacked off, we remove all masking carefully and inspect the entire conservatory for even coverage and clean edges. Any minor touch-ups are completed at this stage. The whole project is typically finished in a single day for a standard-sized conservatory, or two days for larger or more complex structures.
The paint is touch-dry within a couple of hours, but full curing takes 24 to 48 hours. During this time, we recommend keeping conservatory windows closed if possible and avoiding touching or leaning anything against the freshly painted surfaces. After 48 hours, the finish is fully hardened and the conservatory can be used normally.
A common concern is whether dark colours like anthracite grey will cause the conservatory to overheat. In practice, the colour of the UPVC framework has minimal impact on the internal temperature of the conservatory because the framework represents a small proportion of the total surface area. The glass panels, roof material, ventilation, and orientation of the conservatory are far more significant factors in determining how hot it gets. We have sprayed thousands of conservatories in dark colours and have never had a report of heat-related issues with the UPVC.
The type of roof does not affect whether the framework can be sprayed. Whether your conservatory has a polycarbonate roof, glass panels, or a solid tiled roof, the UPVC bars and trim around it can all be sprayed. We mask and protect the roofing material during the process, regardless of what it is.
We can spray conservatories of any age, from relatively new builds to structures that are 25 years old or more. The only requirement is that the UPVC is structurally sound. If the frames are cracked, warped, or if the sealed units have failed extensively, it may be worth considering whether some remedial work is needed before spraying. During our site visit, we will be honest about the condition and let you know if there are any issues to address first.
In most cases, spraying a conservatory does not require planning permission because you are not altering the structure. However, if your property is in a conservation area or is a listed building, it is always worth checking with your local planning authority before committing to a colour change. Heritage colours like cream, green, and muted greys are usually accepted even in sensitive areas.
The visual transformation of a sprayed conservatory is one of the most dramatic changes we deliver. A white conservatory that has been in place for 15 to 20 years typically looks faded, slightly yellow, and very clearly dated. After spraying, the same structure looks like a modern, purpose-built extension that was designed to complement the house.
The impact is even more striking when the conservatory is sprayed to match the house windows and doors. Suddenly the conservatory looks like an integral part of the property rather than an afterthought. We share regular project photos on our website and social media, and our before and after gallery shows real examples of conservatory transformations.

Full conservatory replacement is the most expensive option, typically costing £8,000 to £25,000. It makes sense if the structure is failing or if you want to change the size, shape, or layout. If the conservatory is structurally sound and you simply want to update its appearance, spraying at £600 to £2,500 achieves the same visual result at a fraction of the cost.
UPVC restorer creams and liquids can temporarily improve the appearance of faded white UPVC, but the effect is superficial and short-lived. These products do not change the colour, they simply clean the surface and add a temporary gloss. The improvement typically lasts a few months at best before the UPVC returns to its previous state. Spraying is a permanent colour change that lasts 10 years or more.
Many homeowners replace their conservatory roof with a solid tiled roof to improve insulation and reduce the dated appearance. This is a worthwhile upgrade but it only addresses the roof. If the UPVC framework below is still white and tired-looking, the overall effect can be undermined. Spraying the UPVC framework is an excellent complement to a roof replacement, giving the entire structure a cohesive, modern appearance.
The combination of a new solid roof and freshly sprayed UPVC framework is one of the most transformative upgrades you can make to a conservatory. The solid roof improves insulation and usability, while the sprayed framework modernises the appearance. Together, they can turn a dated conservatory into a genuine year-round living space that adds real value to your home.
If the conservatory roof is made of UPVC panels, yes, the panels can be sprayed. However, most conservatory roofs are either glass or polycarbonate, which cannot be sprayed. The UPVC bars, ridge caps, and trim around glass or polycarbonate roof panels can all be sprayed, which significantly improves the overall appearance.
A standard conservatory can usually be sprayed in a single day, including all preparation and masking. Larger or more complex conservatories may take a day and a half or two days. The conservatory is usable again the same day, though we recommend avoiding touching the painted surfaces for 24 to 48 hours while the paint fully cures.
Yes, in most cases. The spraying is done from the outside, so you can continue to use the conservatory during the project. We will let you know if there are any periods where it would be helpful to keep specific doors or windows closed to avoid overspray, but there is no need to vacate the conservatory or clear it of furniture.
No. All internal fittings are protected from overspray because we mask the external surfaces and spray from outside. Your blinds, curtains, and internal finishes are completely unaffected.
Yes, provided the existing paint is sound and well-adhered. If the previous paint is peeling or flaking, it will need to be removed before we can apply a fresh coat. During our site visit, we assess the condition of any existing paintwork and advise on the best approach.
No. Professional masking protects all glass, seals, brickwork, paving, and surrounding areas. We also cover any garden furniture, plants, or other items near the conservatory. At the end of the project, we remove all masking and clean up the site. You should not find any paint where it should not be.
Conservatories are one of the projects where I would strongly recommend hiring a professional rather than attempting DIY. The complex angles, roof bars, tight spaces, and large surface area make it very difficult to achieve an even finish without professional spray equipment and experience. The risk of an uneven, patchy, or dripping finish is high, and correcting mistakes on a conservatory is much harder than on a single window. If you want to understand the DIY vs professional decision in more detail, our guide on whether you can spray UPVC yourself covers the pros and cons honestly.
