Have you noticed your conservatory looking dull and dirty lately? Perhaps you’ve thought about cleaning it yourself, but worry about the high roof and possible injuries? Dirt, moss, algae, and cloudy panels can make surfaces very slippery and dangerous, you know. But there’s no need to put yourself at risk by cleaning it on your own, there are people who can do it instead.
In this post, we look at what affects conservatory cleaning costs. We also explain why regular maintenance matters and how to plan a budget without breaking the bank. By the end, you will know what to expect and how to keep your conservatory shining.
Conservatory cleaning prices depend on several very important factors.
Conservatory size. A small conservatory usually means a cosy little sunroom. Medium has enough space for a table and chairs, whereas a large conservatory can fit a full lounge set or double as a mini garden.
The prices according to size can be:
| Conservatory size | Average cleaning prices |
| Small (up to 10 m²) | £80 – £120 |
| Medium (10–20 m²) | £120 – £200 |
| Large (20 m² and above) | £200 – £350+ |
Regardless of their size though, a conservatory also has different parts that need cleaning. You can take advantage of a full or a partial cleaning, depending on your needs.
| Conservatory part | Average cleaning prices |
| Exterior only | £70 – £150 |
| Interior only | £60 – £120 |
| Full conservatory clean (inside and outside) | £130 – £250 |
| Conservatory roof-only cleaning | £80 – £180 |
Every standard conservatory cleaning service can cover the following:
Extra jobs, like heavy algae removal or tough roof stains, can cost more. So it’s always good to ask what’s included before you book.
The conservatory cleaning cost can differ a lot even when you consider the factors. Why is that?
Let’s first look at not only size but also design. A tiny lean-to conservatory costs less than a big Victorian one. Edwardian styles, in this line of thought, are often pricier because they have more glass and tricky corners. Roof height also influences the price. The higher or more awkward the roof, the more effort and kit needed.
Then there’s the roof material. Polycarbonate panels are cheaper to clean. They are lightweight but scratch easily. On the other hand, the conservatory roof cleaning cost will rise if you have glass roofs. They are heavier and need more equipment to reach every corner. They also show every smudge, which means more elbow grease and more cost. You can clean the inside of the conservatory roof on your own, but the exterior is best left to a pro.
The condition and level of soiling also matter. Algae, moss, or lichen build-up. They can push the conservatory cleaning price up, so a neglected conservatory will cost more than one cleaned regularly. Think of it as paying for years of “I’ll get to it later.”
Accessibility is another big factor. If the conservatory is tucked behind a fence, in a tiny garden, or hard to reach from the house, it will slow down the cleaners. They will resort to ladders, scaffolding, and water-fed poles to clean the awkward spots, which add to the price.
And while we talk about accessibility, we can’t leave out location. London and the South East usually have higher internal and external conservatory cleaning costs than the rest of the UK. Travel, parking, and traffic jams all sneak into the bill. Even a short hop through a no-parking street can add a few pounds here and there.
Many cleaning companies offer extra services. Sure, it may increase the price a bit, but you can often get a discount for bundling jobs. Not to mention the time it will save you. Here are a few additional services that can easily be combined with conservatory cleaning and which are just as important for a home’s good maintenance:
DIY can certainly save some money upfront, but it comes with significant risks.
Climbing ladders, reaching lofty glass panels, or slipping on moss is not exactly enjoyable, or safe. Professional cleaners, on the other hand, bring the proper gear and know-how. They can deal with heavy dirt, algae, and moss without harming your roof or ending up in a comedic fail video.
It should be said that regular cleaning is more than just keeping your conservatory sparkling. It actually saves money in the long run. Dirt, moss, and algae left alone can damage the roof and frames. In that case, you will need repairs and they cost a lot more than cleaning. Keeping everything tidy also makes your conservatory look nicer. If you ever decide to sell, a well-maintained conservatory can even increase your property value.
Some window cleaners do offer conservatory roof cleaning. However, not all have the right equipment or experience for delicate or high roofs. It’s worth asking before you book. You don’t want scratched panels or a wobbly ladder incident.

Yes, conservatory roofs can be pressure-washed, but only if you know what you’re doing or have someone who does.
Pressure-washing a conservatory roof can damage it. High-pressure water harms polycarbonate panels and loosens glass roof seals. Professionals use low-pressure cleaning or soft brushes with a solution, which is safer and avoids repairs.
If you book professionals, you will see a small conservatory cleaned in 1-2 hours, a medium one in 2-4, and a large one in half a day or a bit more. They have the right tools, ladders, and techniques to get the job done quickly without risking a slip or scratch.
Again, it depends on size, roof type, and how dirty it is.
If you go the DIY route, you will need a few hours for a small conservatory. On the other hand, a large Victorian or Edwardian style could take a full day or even a weekend. You’ll be climbing ladders, moving furniture, and scrubbing stubborn moss. It’s exhausting and not exactly what you want for your weekend.
A little regular care always beats a big, expensive repair later. Most conservatories benefit from a cleaning once or twice a year. Spring and autumn are good times.
Heavily shaded or tree-covered properties need 3 to 4 times a year because dirt, leaves, and moss accumulate faster.
