large edwardian conservatory

Are you thinking of building a conservatory, but you’re not sure how much a conservatory costs? Maybe you’re on the hunt for the best ways to save money, or even looking to create a budget for your project. No matter what stage of the conservatory build you’re in, taking the time to research project costs is a vital part of getting the most out of your budget. In this article, we’re going to talk you through the cost of absolutely everything to do with building your very own conservatory.

What are the Main Factors that Affect a Conservatory’s Cost?

There are many different factors to consider when building and designing a conservatory that could affect the cost.

Structural Design

Conservatories come in a wide range of structures, from simple rectangular lean-to builds to ambitious multifaceted designs. The structural design of your conservatory is one of the biggest factors that will affect its cost, so it’s important to take this into account when budgeting.

Sizing

Perhaps the second most important factor which will affect the cost of your conservatory is its size. The larger the conservatory you want, the more materials and labour will be required, which of course means a greater cost to you.

Frame Materials

Conservatory frames are typically constructed from one of three materials: uPVC, wood, or aluminium. Each material offers its own set of benefits, but of course each has a different cost attached. On average, aluminium and hardwood are more expensive than uPVC.

To put this into context, a standard-sized Victorian uPVC conservatory may set you back anywhere between £360 - £700, whilst aluminium is more costly at £440 - £820 and a hardwood structure can average as high as £760 - £1080. (source: homehow)

Roofing Material

There are three main choices when it comes to conservatory roofing. Opting for a classic polycarbonate conservatory roof is definitely the cheapest option, followed by a glazed roof, with the more modern tiled or “warm” conservatory roof being the most expensive. Each of these options has its set own advantages, so it’s important to decide which is right for your tastes and your budget.

Glazing

The glass used in your conservatory will typically be either double or triple glazed. Conservatory glass is also available in a range of different options to accommodate the functional needs of your extension. Standard glass is the most budget-friendly choice whilst self-cleaning glass can be up to 20% more costly, solar, toughened, and acoustic glass up to 25% higher in price and decorative glass can reach up to 50% more expensive.

Furnishings & Extras

In order to make your new conservatory a liveable part of the property, you’ll also need to invest in furnishings and finishings. This includes everything from flooring, electric outlets, heating and lighting to furniture, décor, paint, and blinds. You’ll need to ensure there is enough money incorporated into the budget plan to cover these essential extras.

How Much is a Conservatory on Average?

Whilst the total cost can vary massively depending on all of the factors named above, the average cost of a conservatory is £15,000. However, to give you a clearer idea of what you could expect to spend, we’re going to break down the average cost of a UK conservatory for a variety of the most common shapes and styles.

In terms of frame material, the cost of a wood conservatory can range anywhere from £5000 up to £29,100. Remember this will heavily depend on sizing, design and structure plus construction costs will vary from tradesperson to tradesperson. For a uPVC conservatory, you could be spending on average £3900 to £66,700 whilst an aluminium build is costlier still at £4000 to £73,800. (source: homehow)

Sizing & Design

As mentioned previously, both the sizing and structural design of your conservatory will have a significant impact on the overall cost. There are many different conservatory styles out there to choose from, each offering a different look and feel for your property.

In this section, we’ll be exploring the average costs for Lean-to, Victorian, Edwardian, Gable, and P-shaped conservatories in a variety of dimensions.

Lean-to Conservatories

Popular for its simplistic design and good affordability, the lean-to conservatory incorporates an angled roof which ‘leans’ downwards across the three walls of the structure. For a fully glazed 3500mm x 2000mm polycarbonate lean-to, you’ll typically be within the range of £5,750 - £7,250. The glass alternative is a little more expensive, pricing in at an average of £6,250 - £7,750.

Victorian Conservatories

Commonly spotted as part of both traditional and contemporary homes, the Victorian conservatory features a more classically designed structure with a bay front, steeply pitched roof, and ridge detailing. To install a fully-glazed 3500mm x 3500mm Victorian conservatory you’ll be averaging around £9,500 £11,000 for a polycarbonate roof structure and £9,250 to £10,750 for glass.

Gable Conservatories

Designed to maximise height, light and space, gable conservatories combine a squared or rectangular internal room shape with an upright gable front structure. A dwarf wall gable conservatory in 3500mm x 3500mm dimensions will generally cost within the higher range of £11,500 - £13,000 for a polycarbonate roof structure and £12,000 - £14,000 for glass.

P-Shaped Conservatories

P-shaped conservatories are ideal for maximising internal space whilst still maintaining a balanced and even sense of flow across the back of the property. Structured to extend in different directions, the P-shaped style can be used to form multiple living spaces within the extension and is often spotted on larger, detached homes.

Due to the nature of the design and structural use of materials, P-shaped conservatories typically fall at the higher end of the budget scale. On average, a 3500mm x 3500mm polycarbonate dwarf wall P-shaped structure may cost between £12,000 - £14,000 with a glass roof pricier still at £13,250 - £15,000.

What About a Tiled Conservatory Roof?

Although polycarbonate and glass are two very popular choices, roof tiles offer an alternative look and style plus can even help to improve the thermal and noise insulation of your conservatory space. So, how much does a tiled conservatory roof cost?

For professional installation, a tiled conservatory will typically set you back around £650 to £850 per sqm. However, this price will of course depend on the size and style of conservatory as well as the type of roofing tiles used.

To give you a better idea of how this would price up in a full-scale conservatory project, let’s look at a few examples:

Planning Permission & Building Regulations

On average, the typical cost of planning permission for conservatory construction in the UK is around £200. However, you’ll be pleased to know that this additional cost is often avoidable if specific planning permission regulations are strictly adhered to for the build.

To build without the need for planning permission, you will need to ensure your new conservatory doesn’t:

  • Cover more than 50% of the land around the ‘original’ house
  • Extend higher than the tallest section of your home’s roof/eaves
  • Extend over 4m past the rear wall of your property
  • Incorporate raised platforms/any alterations to the existing property roof structure

Planning permission may also be required IF:

  • You are building within 2m of the property boundary with an eaves height higher than 3m
  • The conservatory is front of the principal elevation or side elevation near a highway
  • You live in a listed building
  • Plan to make any changes to your home’s structure that are not permitted

More info: Planning Portal

We always recommend that you carefully research and consult your local planning authority before beginning your project to be 100% sure where you stand in terms of planning permission.

Before you begin construction on your conservatory, you will also need to ensure that extension building regulations are met. For this, it is recommended that you hire an experienced tradeperson listed under the competent person’s scheme. If you hire someone that is not registered, you may need to pay for building approval. The price for this will differ between local councils, however it can cost anywhere from £700 - £3000.

Once again, make sure to consult expert advice to guarantee all necessary regulations are fully adhered to. 

Extra Costs to Consider

The basic construction of your conservatory isn’t the only factor you’ll need to factor into your budget plan. There are a variety of other costs throughout the project that will also need to be considered.

Groundwork

Before commencing construction, the ground beneath should be fully prepped and ready to support installation. This means, you may have to excavate the area to level out the earth and create a stable, sturdy base level for your new conservatory. When hiring a professional, excavation can cost from £30 to £50+. (source: homehow)

Drainage & Pipework

It is also hugely important to make sure you have adequate drainage linked to the water supply. If not, you might be faced with costs of £700 - £1000 on average for professional pipework installation. (source: homehow)

Guttering

To minimise the risk of water damage and protect the foundations of your new conservatory, it is vital that a guttering system is in place. Conservatory guttering costs anywhere between £12 and £16 per metre. (source: homehow)

Blinds

Conservatories are very open and airy in design to allow as much natural light as possible into the space. To still maintain a necessary level of security and privacy within the room, you will probably want to invest in blinds for your conservatory windows.

For just the blinds themselves, roman style blinds can cost, £20 to £60, venetian blinds around £10 to £30 and vertical blinds £16 up to £100 on average. Professional installation is typically not included within these prices, so an extra £20 – £50 should be added onto the budget to accommodate if needed. (source: homehow)

Heating

A conservatory is a pretty substantial investment – one that you’ll likely want to make use of all year round. The issue is conservatories can get a little chilly in very cold weather just simply due to the nature of their construction. This problem is an easy fix however with the use of internal heating.

A common conservatory heating choice is the installation of an electric radiator. These generally cost between £100 to £150 to purchase and then fit. For those looking to spend a little extra, underfloor heating is another option at around £60 to £100 per square metre for professional installation. (source: homehow)

Cost of Hiring a Tradesperson

The most practical way of planning potential costs and managing spending is to understand what exactly it is you are paying for. Unless you are building your new conservatory DIY, professional labour costs will take up a substantial portion of your budget for the project.

The cost of labour will of course differ dependant on the scale of the build, the complexity of the structure and maybe even the area of the country you live in. However, a base level price point to work from when hiring tradespeople is generally around £150 to £200 per day of service.

To build a fully-functioning conservatory space, you may also need to hire a roofer, electrician, window fitter and even an interior decorator. The typical cost for each of these averages around:

  • Roofer - £15 - £25 per hour/£150 - £200 per day
  • Electrician - £30 - £60 per hour
  • Window Fitter - £10 - £20 per hour
  • Interior Decorator - £100 - £300 per day

(source: homehow)

Labour Costs vs Timescale

So, we’ve averaged that a typical tradeperson may charge anywhere from £150 to £200 roughly per day in the UK. But, how many days will construction actually take?

The best way to gain a good estimate of the costs you could actually be faced with, is to apply daily costs to your specific conservatory project. Below is a table displaying a variety of conservatory styles vs the average timeframe of the build and how this would relate to overall costs.

Breaking Construction Costs Down into Stages

There are multiple stages within a conservatory construction job which factor in varying levels of cost for the project. (source: homehow)

Building a Base

The first step is to excavate the ground to create a sturdy and robust surface for your conservatory. The floor is then levelled, and a concrete base is formed. This typically costs around £90 per sqm.

Dwarf-Wall

Next, a low dwarf-wall is built to provide additional support for the conservatory structure. Dwarf wall construction is usually priced around £50 to £300 per sqm.

Conservatory Roof

A roof will then need to be constructed from your chosen roofing material. Polycarbonate roofs range from £2,200 - £7,300, glass from £2,400 to £8,000 total and tiles £650 - £850 per sqm.

Fixtures & Fittings

The final stage is installing the necessary fixtures and fittings including doors, windows, furnishings, and décor.

  • Conservatory window fitting costs - £150 to £200 per day
  • Conservatory door fitting costs - £390 to £900
  • Conservatory lighting fitting costs - £60 to £100 per light
  • Conservatory decoration - £100 to £300 per day

Is a Conservatory Cheaper than an Extension?

The simple answer is yes, a conservatory build is far cheaper than that of an extension. On average, a conservatory project can cost anywhere from £12,000 up to £20,000+. In comparison, a single storey extension of say 5m x 5m could set you back around £30,000 to £50,000 minus professional fees, VAT, building regulations etc.

Two-storey extensions push the price up even further to between £60,000 and £80,000 with a bathroom extension adding on at least £5,000 and a kitchen £10,000. In most cases, this won’t even include the cost of windows, fixtures, and fittings either.

So, a pretty substantial price difference.

(source: orangeries-uk)

Does a Conservatory Add Value to Your House?

As of July 2021, the average UK house price sits at around £256,000 according to the ONS. Studies have shown that a conservatory can add anywhere from 5-10% extra value to your house, averaging out roughly at around 7% in most cases.

To put these figures into context, if you were to install a high-quality conservatory extension to your property, you could see an increased home value of up to £17,920 when installed on a £256,000 house. This averages out at the 7% increase. Say you spent £12,500 overall on the project, you could realise a potential profit of £5,420 or more!

Future Costs of a Conservatory

With your new conservatory built and ready to enjoy, it is worth bearing in mind the potential future costs of maintaining and repairing the structure when needed.

  • Tiled Roof Leaks: If you have a tiled conservatory roof, water leakages may be repairable by simply replacing broken/missing roof tiles. The cost of this is usually around £120 to £200.
  • Roof Replacement: If too beyond repair, your entire conservatory roof structure may need replacing. The cost of polycarbonate roof replacement ranges from as low as £2200 for a lean-to and as high as £6700 for an Edwardian. Glass roofs are more expensive to replace starting at £2400 all the way up to £7300.
  • Misted Glass: Misted glass is often a sign of failed double-glazing. To fix this problem, you will need to replace the double-glazing which can cost from £50 up to £450 per pane.
  • Conservatory Cleaning: Conservatories should be cleaned on a semi-regular basis to ensure the structure lasts as long as possible. If you’d rather hire a professional to carry out the clean, you’ll probably be faced with costs of around £300 to £650 to clean both inside and out.
  • Conservatory Removal: If for whatever reason, you ever plan on removing your conservatory structure, prices average at around £300 to remove the roof and windows, £20 per metre for the dwarf wall, £120 per sqm for base de-construction and £70-£300 for waste removal.

Are Conservatories Worth it?

So, after weighing up every area of pricing as well as hidden and potential costs too – is building a conservatory actually worth it? Well, we think so.

Conservatories not only add fantastic additional space and style to a property, but they can even be a sound investment, adding up to 10% value to your home. When compared to an extension, the costs of a conservatory are also far lower, meaning you can enjoy an expanded, enhanced living space for less.
