But when it comes to fully fitted conservatory prices, what exactly should you expect to pay for your new living space?

How much do conservatories cost is a pretty vague question, the conservatory price you will receive can vary widely depending on:

 

  • The size

Fully fitted prices are really what you want to be shooting for as builders and companies are notorious for mentioning hidden costs further down the line.In this prices guide, we’ll look at the different types of conservatories, which makes up the cost and the average cost of each style.

Conservatory Costs - What Makes Up The Price

The prices of conservatories per m2 vary widely up and down the UK and this due to several certain factors, not least the construction materials used and the labour involved. Some new conservatory builds will require far more tradespeople and expertise than others. 

Because there is no average conservatory cost that you can rely on, In this section, we break down all the aspects that could go into a new conservatory installation and what impact they could have on the final price.

Types of Conservatories and Associated Costs

Lean-To Conservatories

A Lean-to is your basic conservatory and are the most common style in the UK. Featuring a three-sided design and usually with a polycarbonate glass roof, they generally take less time to construct than other forms. These are also what you would expect to see if you want a budget uPVC and glass conservatory or if you are searching for cheap conservatory prices.

Edwardian Conservatories

The Edwardian conservatory is the second most common type from the wide range open in the UK and features a rectangular design which provides extra space than its lean-to counterpart. They are usually built with a small brick wall and installed with a polycarbonate glass roof as standard.

Georgian Conservatories

The Georgian conservatory is sometimes referred to as a reverse-drop or hipped-back Edwardian. Many people confuse Georgian conservatories with Edwardian, but there are a few key differences between the two. One crucial distinction between them is that a Georgian generally has a larger footprint. This means you may need to obtain permission.

Victorian Conservatories

One of the period conservatory types that can be found in rural or urban homes. These particular models are sometimes referred to as sunrooms as they provide a rounded appearance with a high conservatory roof.

P-Shaped Conservatories

A P-shaped conservatory combines the styles of a lean-to conservatory and a Victorian. It features an elongated room with a short, round addition. This type takes up a good deal of ground area, so it is generally only suited to larger detached house. 

T Shaped Conservatories

T-shaped conservatories are great for those who want to add multi-functional living space to their property. The main difference between the two styles is shape and size; are designed to run alongside a long wall. T-shaped conservatory costs can be more than others.

Gable Conservatories

The Gable is characterised by its vaulted glass-panelled conservatory roof. The glass panels allow for maximum natural light and enhances the design’s bright, airy feel. These conservatories make great sunrooms, playrooms and pool enclosures. 

Conservatory Sizes - How Big Should a Conservatory Be?

The conservatory size that you choose will have the most significant impact on price bar none. Conservatory prices are worked out on the basis of a square metre which you will often see quotes that reference the m2 metrics.

The smallest is usually 3m x 3m conservatories, and these are particularly small if the purse-strings allows I would recommend going more extensive than this shoebox size. In terms of a maximum, you can cover up to 30sq/metres of floor area before permission needs to be granted.

Groundworks and Foundation - The Conservatory Base

The conservatory floor will need to be built on a safe and solid foundation that is free from damp issues and suitable for a conservatory structure.
This means that a wet garden area that retains water and doesn’t drain well will need to be removed.

The same with a solid concrete pad that collects water. An area like this would not be ideal for building a conservatory. When replacing an existing conservatory, alot of thetime the brickwork can remain. 

Access

One of the very first aspects of the project a potential installer will look at is the access. If you have a side gate don’t need to worry.

But if you have terrible access before conservatory companies even arrive, try to work out how the access will be, how you can improve the situation before they start the quotation process.

Conservatory Roof Costs

There are more options now with conservatory roofs than there has ever been and this is one part of your new conservatory you will want to think about
tiled conservatory roof. A solid roof is a lot better than a polycarbonate glass roof as well as being a lot more expensive.

Polycarbonate conservatory roof

A polycarbonate roof is the first option that most conservatories came with, they are low cost and cheaper than tiled conservatory roof choices, and for a lot of people work perfectly fine. The chief complaints with this conservatory roof over a solid roof, is they lose heat in the winter and are too hot in the summer. If you can go for a solid roof.

Solar Conservatory Roof

New to the conservatory roof market, these conservatory roofs block the sun’s glare and because they are a solid roof they help with furniture fading.

Dwarf Walls (half brick) or Fully Glazed

Simple enough! You will need to choose between whether you would like the first half of your conservatory sides to be brick or a dwarf walls as they say in the trade, or whether you want a uPVC fully glazed conservatory.

Heating the place

When heating conservatories, you’ll also need to comply with regulations if it is independently heated.

Before consulting with a company or builder, it’s a good idea to check with your local planning authority as to whether the structure will need to meet specific standards. For additional heating solutions in the winter, for instance just use a heater.

Double Glazed or Triple Glazed

Most new conservatories are double glazed as standard, years ago many wooden conservatories would be single glazed, and this would be a nightmare for heat control. Double glazing put a stop to this and was a lot more energy-efficient. Times have changed again, and triple glazing has entered the market. The benefit of triple glazing is as follows:

While many people will still opt for double glazing in their new living space, for the extra cost a triple glazed conservatory is worth asking about.

Wooden VS UPVC Conservatories

Hardwood conservatories look fantastic and certainly have a place in the market. On older homes like farmhouses, a uPVC lean-to conservatory may well look out of place, if the original dwelling is all wood and double glazing then uPVC will stand out for the wrong reasons.

Secondly, maintenance is an issue, like anything on your property that is built with wood, regular maintenance like painting will be essential. Surprisingly UPVC is cheaper than wood, less maintenance and in most cases more modern.

Guarantees and Warranties

Reputable conservatory companies will always provide comprehensive warranties with the price of a conservatory. Fly by night cowboys who don’t expect to be in business in say 5 years, don’t think about this. Therefore they don’t include these possible hidden costs in their conservatory quote..

Always make sure if your going fully fitted that the conservatory price you get includes an extensive warranty, and if possible, you want independent insurance backed guarantees.

It's not just the conservatory design and size that impacts the price.

Building Work Requirements

Building work on conservatories, if it is required, affects the price considerably. Section 3 of the Building Act defines building work as” work for or in connection with the construction, demolition or removal of a building.” If you’re rebuilding, replacing or upgrading an existing conservatory you may need a building permit. It will need to signed off for structural integrity. Again this will increase the price.

Planning Permission Requirements

Whether or not your conservatory building will require planning permission from your local authority will depend on the size of the structure on a square metre basis.

It shouldn’t need planning permission if it doesn’t stretch farther than 0.9 metres past the wall of your property and the conservatory roof doesn’t rise above the tallest point of the property’s roof.

How far can you push it?

Those with semi-detached or detached homes have a little more wiggle room with fully fitted conservatories; it can stretch to a maximum of 70 cubic metres from the property or 15% of the property’s volume up to 115 cubic metres (whichever measurement is larger).

Planning involves an extra cost, so speak with a contractor about whether permission will be required or not.

Building Regulations

The UK Government has implemented building regulations to ensure that all new buildings meet minimum safety and security standards. In most cases, conservatories do not need to comply with building regulations, but there are a few circumstances in which the rules must be met.

If your conservatory will be built above ground level, for instance, or stands entirely separately from the property, government building regulations will apply. It’s challenging to get an exact conservatory cost calculator.

How is it different from an Orangery?

The terms “conservatory” and “orangery” are often used interchangeably, but the two structures are not the same. An orangery is a more substantial building, more high-end addition to a property, with less double glazing, but building one typically requires approval from a local authority where lots of conservatories are built without. A lot of people upgrade from an existing conservatory to an orangery.

 

Is a DIY Conservatory an option?

A quick word on DIY conservatories, they are a great option if you know what you’re doing, or you have a qualified conservatory installer on hand to help. The UPVC windows installation needs to be done by a pro, or else drafts will forever plague you. And conservatory roof obviously will be leaking if not done correctly. Prices and costs will be lower with this option, yet so will the headaches.
