DIY Conservatory Installation Options
If you’re confident in your DIY skills, you may want to install a conservatory yourself to save some money.

If you’re in any doubt, always hire a professional conservatory installation company. Here are some prices for conservatory materials from Trade Price Conservatories:
- The materials for a lean-to conservatory with dwarf walls will cost between £2,039 and £3,018

Nevertheless, you are sure to save a large lump sum on labour costs, and can always haul in a couple of friends to help out if things get on top of you. Just remember – only those proficient in DIY and confident enough to scale a ladder and carry out this type of building work should engage in this type of DIY installation project.
Conservatory style & cost considerations
The fist step before estimating the cost of a new conservatory is to determine its style and purpose.
The design specifications of a conservatory will affect the cost of a conservatory greatly. The cost increases depending on the size, style, build and type of materials that will be used.
Always, know what you are after and plan your budget accordingly. The cost of a small conservatory is different from this of bespoke one. The usage of newly created space can have many different functions such as a playroom, an office or even an extra lounge.
The style of conservatory you choose should complement the size and shape of both your house and garden. The traditional Victorian conservatory (often accompanied with bay windows) offers an elegant and classical look, although the circular floor plan will make furnishing more difficult compared to the rectangular Edwardian style. For these conservatories lantern-roofs are great additions for grander, older homes and suggest a more open, spacious feel.
On the other hand, an L-shaped extension is suitable if you want your conservatory to embrace the main building rather than stick out. If these options are slightly over-budget, however, or you’re looking for a modest alternative that doesn’t completely consume the remaining garden area, a lean-to sloping roof conservatory is a simple yet effective choice.
The following table provides estimates on the cost of bespoke conservatories, to help you get an understanding of how the design influences the cost.
|Bespoke Design||Frame Material||Price Guide|
|T-shaped Edwardian Conservatory||Any||£14,000 to £25,000|
|L-shaped Lean-to Conservatory||Any||£12,000 to £20,000|
|P-shaped Victorian Conservatory||Any||£12,500 to £20,000|
Victorian Conservatory Prices
A Victorian conservatory, otherwise known as a ‘Victoriana’ is a quintessential, traditional English extension. This type of conservatory is also extremely versatile; it can be attached to all types of property whilst still remaining a cost-effective option. It depends on the size and materials you decide to use, but a Victorian or Edwardian conservatory will set you back somewhere between £10,000 and £15,000.

Conservatories cost based on material
On the biggest factors that affect the price of conservatories is the materials that they are made from. uPVC is the cheapest material when compared to wood and aluminium but its quality its quality and style cannot be compared to other more expensive materials. Hardwood conservatories are the next best option but cost on average 40%-50% more. The cost of PVC conservatories starts from £5,000 whilst hardwood conservatories start from £10,000 and can range £100,000 + depending on the size and any special features.
A wooden or timber conservatory will cost between £20,000 and £50,000 depending on which type of wood you will choose and the size and style that you will go for. Wooden conservatory prices can vary greatly depending on the supplier, so be wary and do proper market research to find a supplier with good rates. For oak frame design expect to pay from £40,000.
Wooden conservatories are conservatories that have been built with a wooden structure. If you want a traditional look, you might want to opt for a timber conservatory rather than a uPVC model. While it might look great, be aware that wood needs more maintenance than uPVC and will require regular weatherproofing to ensure that it doesn’t rot or warp.
Wooden conservatories prices may vary greatly in areas that have wood scarcities. Hardwood conservatory prices can also be a lot higher than softwood conservatories but are more durable and require less preparation.
To achieve a well-finished look for a home that contains many wooden frames and doors, it will require extra maintenance and money but at the end, it is worth it as you maintain your homes natural look.
Because of their more complex structure, hardwoods such as beech and elm provide increased stability and durability for most wooden conservatory models. Their high-density level ensures they will last a long time, and the naturally occurring grain provides an authentic and environmental feel to the extension’s exterior. Hardwood conservatory prices generally fall somewhere between £12,000 to £28,000 for an average hardwood conservatory.
|Size||Full Installation||Supply Only|
|25 m2||£50k||£12,000 – £15,000|
|40 m2||£80k||£15,000 -£20,000|
|65 m2||£100k||£35,000 – £100,000|
Oak is one of the most popular wood types used in conservatory construction, and because it is so widely and readily available it can usually be found for as little as £10,000 per extension. Oak is also, however, very strong and can be manufactured to be very bug and pest resistant while maintaining its polished veneer; oak conservatory prices for the most expensive type of oak can often reach as high as £100,000 for a new conservatory.
Engineered timber usually refers to the different types of wood cheaply available after the trees have been felled but before the wood has been treated in various factories or plants. This type of wood can often be picked up at a discount price because of it’s lack of a clean finish and generally rough exterior, but it is still a strong and sturdy option that can always be treated by you or your team at a lower price. The cost of a timber conservatory will vary depending on the type of wood, but prices usually start anywhere from £30,000 to £45,000.
The type of wood you choose, however, isn’t the only thing that will affect the price of your new conservatory; the size, style and quality of materials for your final conservatory design will affect the final pricing. According to timberconservatory.com, the final cost of a wooden conservatory might be anything from £20,000 to £60,000 – but for the most accurate figures for budgeting purposes, you should obtain as many free quotes as possible from a variety of different conservatory contractors and retailers. That way you can be sure you’re getting the best deal available – whatever the type of wood you choose!
Historically, an orangery was an ornate type of greenhouse; the term is now used to describe more elaborate, luxurious conservatories, which in turn usually cost more than ordinary conservatories:
- A 2m x 4m orangery including all major features and fittings; including double glazing, hardwood doors, down-lights, flooring, VAT and installation will cost between £40,000 and £50,000
Orangery conservatories are more suitable for double glazing windows for added security to your home. The bricked walls also make this type of conservatory look more natural when it is added to your home.
uPVC is the most popular conservatory material nowadays because it’s cheaper than wood, as well as more durable. The uPVC is offering the minimal maintenance and a long-lasting opportunity from occasional cleaning.
|Size (cm)||Type||Frame Material||Roof Material||Price range|
|350 x 250||Edwardian||Wood||Glass||£8,500-£11,000|
|350 x 250||Edwardian||uPVC||Glass||£5,500-£9,000|
|350 x 250||Lean To||Wood||Glass||£7,OOO-£9,000|
|350 x 250||Lean To||uPVC||Glass||£6,800-£9,000|
|350 x 250||Victorian||Wood||Glass||£12,500-£14,500|
|350 x 250||Victorian||uPVC||Glass||£11,000-£12,500|
Usually, uPVC conservatory prices include the conservatory as well as installation, VAT and a 10-year guarantee. Costs can vary for different locations and for different conservatory installation companies.
uPVC conservatories look great in modern buildings and can function well as greenhouses. Adding a uPVC conservatory will increase your property value tremendously and is a great idea if you are trying to get your home sold a lot sooner.
Aluminium conservatory prices
Aluminium is another material that is worth considering for conservatories as it is extremely strong and therefore good for supporting full-length windows rather than dwarf ones. Aluminium won’t rot, warp, twist or rust, the only drawback is that aluminium conservatory prices can be 10% higher than other types of conservatories. Aluminium conservatories can also be painted any colour so your home and yard can seem brighter.
The conservatories price can be quite expensive especially when you adding extras like painting and decorating. Also buying conservatory furniture and adding ventilation or heating will increase the cost. However, it is possible to get a cheaper conservatory if you choose your materials and style wisely.
To cut back on lean-to conservatory prices you need to do effective market research so you can find a supplier and construction company who will provide you with good quality materials at a lower cost and still do expert constructional work.
A standard, lean-to uPVC conservatory will cost less, for example, than a large, wooden Edwardian conservatory. You can also make sure you pay less for your conservatory by choosing regular double glazing and simple doors, for example:
- The cheapest 2.21m x 2.237m conservatory from Direct Conservatories4U costs £1,745
Creating a smaller conservatory might not be the best way to save money because construction costs and legalizing conservatories on house plans raises small conservatory prices a lot more than you might expect.
Small conservatory prices
A small low-cost conservatory in the range of 2,5 x 3,5 metres will likely cost between £5,000 and £7,000. Even the smallest of conservatories can improve your property value and is worth the investment and effort. Small conservatories are becoming more popular in smaller units because it is often the only way residents can enjoy sunlight in their homes.
Lean to conservatories
A lean to conservatory is usually installed with a basic floor plan of rectangular shape. These conservatories utilize the space well and maximize the sunlight entering the room. Compared to other types, lean to conservatory prices are low. Since there are a number of options available, the costs do vary. Let us take a deeper look at how lean to conservatory cost gets affected?
Lean to conservatory designs are flexible and feature many options; you can select any of these as per your desires. For the base, you have three main choices, which are dwarf walls, full glass models and raised uPVC panels. As for the roof, you can either opt for glass or polycarbonate. Glass allows more light to enter, but polycarbonate is a more affordable option.
A number of features are offered with a lean to conservatory to make it secure and prevent an intrusion. With every feature that you choose, prices will rise. The most common of these are internal beading on the glass, force resistant hinges, multi point locking system for the doors and shot locking mechanism for the windows. You can also opt for toughened glass.
Some installers offer a guarantee with lean to conservatories. This covers the installation value and deposit cost. Failure to comply to building policies must also be included.
Lean to conservatory cost
The cost of a lean-to conservatory will be largely determined by its size, but generally, you should expect to pay around £10,000 for an average sized version. However, it is possible to build a small lean-to conservatory for as little as £7,000.
Remember not to shy away when it comes to hiring a professional conservatory installer who will do the job properly and with quality materials. Make sure to compare quotes from three or more contractors in order to get a competitive price; always check references and insurance credentials before you hire.

How much does a conservatory size 3×3 cost?
If you have ever tried purchasing a conservatory, it is very possible that you have gone back home inconclusive of how much a conservatory really costs due to the different prices you got from different sellers. Be rest assured that there are factors contributing to these price differences.
A complete build 3×3 conservatory can cost between £8,000 and £15,000. This rather massive variation is caused by a number of factors ranging from quality to abnormal site conditions to salesmen who only earn from commissions.
In search of a 3×3 conservatory? It is pertinent to know what questions to ask and where to get the valid answers from.
Your 3×3 Conservatory Options:
Firstly, you have to know what you really want. You might think you already do but think about your options.
- Do you have an already existing conservatory that you want to replace or are you building from ground up?
- Are you going to employ a conservatory specialist to oversee the project from start to finish or are you going to employ the services of your own builder?
- Will you employ a fitter to complete the job or will you rather complete it yourself?
Replacing an existing 3×3 conservatory
This comes quite easy. You get to choose the kind of roofing material you want and the spots you want your windows. The cost required to complete a 3×3 conservatory can be kept below £7,000 if you are replacing an existing one unless you intend to add extra features. If you are building from ground up, don’t be too quick to decide that it is a project you can handle by yourself until you have weighed in on the available facts.
The Cost of 3×3 conservatory base
The base work comes first. Observe the house wall that is meant to become the back of your conservatory closely because the presence of obstructions on this wall will definitely affect the cost of your conservatory. You have to really think about things like garden taps, heating boiling vents, kitchen waste water pipes and rainwater downpipes. Underground services, wastewater inspection covers and tree roots should also be taken into consideration.
Take note that a 3m×3m Lean-To conservatory (inner measurement) must have a measurement of 3.6 metres as its external width to give room for a double skin wall when the space in your garden is being measured.
The cost of 3×3 conservatory flooring
Working with a budget and trying to manage cost should not leave the insulation of your floor out of the project. It is inexpensive and would help keep your conservatory floor warm in winter. Be sure to have a properly insulated and a smooth concrete finished floor.
You need to have figured out a couple of things before the floor is finished to avoid mistakes that will affect the look of the conservatory. Decide on how many electrical outlets that you want and the cost that will be incurred if a screed finish is required.
3m x 3m lean-to conservatory
The kind of flooring you choose for the nine square meter 3×3 Lean-To conservatory floor always has an impact on the cost regardless of the not-very-large appearance the conservatory gives. During winter, a wood floor tends to be quite attractive and gives warmth to the touch but the cost of buying and installing it is high. Tiles are very beautiful and relaxing making summer time awesome but the emergence of winter tells a different tale.
Numerous natural floor coverings that look perfect for your conservatory and give warmth are available. Seagrass being the cheapest. It definitely isn’t the toughest wearing but its price cannot break your account and laying it is quite easy. There is a wide variety of colours and textures that you can choose from.
Choosing the right type of conservatory roof to fit when installing or refurbishing your conservatory is of great importance.
Making the wrong choice for your conservatory roof can result in damaging your conservatory to the extend that it will not be able to repair it in the future. This is why the right selection of roof along with proper installation can save you a great deal of money in the long run.
Solid conservatory roof
Solid conservatory roof systems are designed and engineered to be lightweight, being a great choice for new tiled roof conservatories and also old ones that are being refurbished. More and more homeowners choose to transform (retrofit) their existing conservatory that is too cold in the winter and too hot in the summer so that that they are able to use it during the whole year.
If you are interested in building a new solid roof conservatory, you will need to hire n fitter that is able to handle all the work such as building the base, he walls and fitting the frames and installing the new conservatory roof. If you are refurbishing an old conservatory, the first thing you need to do is to hire a professional surveyor to assess the condition of the existing structure, as it might not be able to hold the additional weight from the solid roof system.
With regards to choosing a roofing material, you can either choose concrete tiles, slate roofing or composite panels. Concrete tiles are a very popular option for house roofing and they can easily match your main house’s roof. The only disadvantage is that they absorb water and therefore they become heavier.
Slate roofing is also another good option if you are looking to give your conservatory a classy appearance and also invest in a long-lasting material too. As an alternative to natural slates, you can choose synthetic ones that both lightweight and long-lasting.
Composite panels is another roofing system that is gaining in popularity in the market as they are made of lightweight material, are energy efficient and also come in a wide range of colours.
Double-glazed conservatory roof
Double glazed conservatory roofs have a lot to offer to an aspiring or existing conservatory owner. Glazed roofs allow plenty of light to come in and also look great in your garden. However, sometimes depending on the location of your conservatory, too much sun might be coming in making them too hot and bright to sit in. Furthermore, double glazzed glass conservatory roofs depending on the noise insulation properties of the material used can make a lot of noise when raindrops hit on the roof, especially when it rains heavily in the winter. Ofcouse, you can offset many of these issues by choosing a different type of glass.
Polycarbonate conservatory roof
Polycarbonate panels are becoming increasingly popular because of the many great benefits they offer. Polycarbonate is very tough, resistant to ultraviolet rays, very attractive and comes in two forms; clear and opaque. Furthermore, polycarbonate conservatory roofs weigh less, cost less and many installers find them quicker to install on conservatories.
Instead of installing a double-glazed conservatory roof, you can easily choose a polycarbonate one as it more economical and also weighs a lot less than a double-glazing roof. In addition, by choosing thinner layers of polycarbonate, you can save even more money but your conservatory will not be insulated in the most efficient way, making it difficult to sit in when it is too cold or too hot outside.
Classic tiled conservatory roof
Homeowners in the UK are gradually investing in classic tiled roofs when it comes to their conservatories and the installation of a new tiled roof as it offers many great advantages. Tiled roofs blend with the overall style of your house easier and look more like an extension. Roof tiles are also available in many different colours, making it easy to find the one that goes well with the rest of the house.
Tiled roofs are also very versatile when it comes to choosing a conservatory design or installing them on an existing one as they can go with any of the existing conservatory styles.
Tiled roofs also block external noises, allowing you to enjoy a more peaceful environment. Solid roofing is also energy efficient, retaining heat when the weather is cold outside and deflect heat when it’s hot outside.
When it comes to roof tiles, there are a variety of colours, shapes and materials available, which can make it difficult to choose the right one. Comparing the features of different types of roof tiles will help to find the right choice for your home, so look at all the factors concerned.
You don’t have to choose traditional tiling for your roof. You may have a metal sheet roof installed, or use thatching, or you might even consider installing a green roof. A green, or grass roof is a fairly recent eco-friendly option, whereby a layer of grass and plants is installed on the roof providing good waterproofing and thermal insulation.
However, roof tiles are still the most common option and there are a variety of materials to choose from, the most common are concrete, clay or slate roof tiles.
Composite roof tiles, made of a mix of materials are becoming popular as they are extremely durable and available in a range of colours – however, they are a more expensive choice.

System tiled roofs get delivered at hour home ready to place onto your roof, as they are pre-assembed in the factory. Two popular sytem tiled manufacturers are Guardian and Supalite.

The cost of conservatory planning permission
The question of whether a planning permission is needed to add a conservatory to one’s property, or not is often asked.
A planning permission is seldom needed to the relief of most of us.
