Types of Conservatory

Lean to conservatory costs

If the name didn’t already give it away, lean-to conservatories are constructed with three walls that join to your home. These styles of conservatory generally employ a sloping roof design and are often the most affordable and quickest type to build.

Investing in a lean to conservatory will typically cost between £9,000 and £14,250 – ideal for those on the lookout for an affordable solution that won’t break the bank.

Victorian conservatory costs

The Victorian conservatory is renowned across Britain for its pitched roof and rounded frontage. With a myriad of options ranging from captivating materials to diverse finishes, you can easily select the type that best reflects your home’s unique style.

To construct a stunning Victorian conservatory in your home, you can expect the cost to range between £12,000 and £17,500.

Edwardian conservatory costs

If you are looking for a classic style of conservatory, an Edwardian is an ideal option. Unlike the rounded frontage that Victorian designs have, these conservatories feature a flat facade which adds a sophisticated touch. Regarding cost and material options, they are similar to those offered by Victorian conservatories; why not opt for the more sophisticated Edwardian?

An Edwardian conservatory typically sets you back between £10,500 and £18,000 – an ideal investment for adding value to your property.

Orangery conservatory costs

Combining the sturdiness of brickwork with glass, an orangery is a magnificent hybrid between a conservatory and an extension. Unfortunately, due to its robust construction, this type of home addition typically comes at a higher cost than other more traditional designs – on average, £32,500 for one measuring 16m2.

Factors affecting the cost of a conservatory

There are several influencing elements when it comes to the cost of a conservatory. Gaining an understanding of these key factors can help you determine the budget for your project. With wise preparation and research, you will be able to locate the ideal conservatory that meets all of your criteria without putting a strain on your finances.

Size: The size of your conservatory will have the greatest impact on the overall cost; if you choose a large conservatory, you can expect to pay more than for a smaller one. To save money, consider whether you really need space for extensive furniture or if a more compact version would still provide enough room for what you require.

Type: The type of conservatory you choose can also affect the cost. Traditional designs tend to be more expensive than contemporary ones, owing to the number of materials and labour required. In addition, adding features such as decorative glass or a sunroom may incur extra costs.

Materials: Different materials used in construction will affect the overall cost of your conservatory. UPVC is typically the most affordable material, while hardwood and aluminium are more expensive but also offer greater durability.

Location: The cost of a conservatory can vary depending on where you live in the UK; prices in London tend to be higher than elsewhere due to increased labour costs and other factors related to the city’s size.

Builder: The company you choose to install your conservatory will also affect the final cost; generally, contractors with a good reputation tend to charge more than those who are less experienced or have fewer credentials. It is important to compare several companies before deciding, to get the best value for your money.

Planning permission: Depending on the size and type of conservatory you choose, you may need to apply for planning permission. This can add extra costs to your project, so it is a good idea to research the regulations in your area before beginning construction.

However, if you want to build a conservatory without paying a fortune? Let’s explore how to get cheap conservatory prices in the UK.

Conservatory Planning Permission

Before you even start to compare conservatory prices, you should check whether you need planning permission to build a conservatory in the first place. UK planning laws state that conservatories are permitted developments, meaning that you can install them as long as they meet guidelines, including:

  • The conservatory must not take up more than half the area of land around the original house
  • The conservatory cannot be higher than the highest part of the house, including the eaves and ridge height
  • A conservatory at the rear of a property must not extend beyond the rear wall by more than 3m on an attached property or 4m on a detached property.
  • The conservatory should be no more than 4m high
    The conservatory must not include any side verandas, balconies or raised platforms
  • If you live in a National Park, Area of Outstanding National Beauty, Conservation Area, World Heritage Site or in a Listed Building you should check with your local council whether you need to apply for planning permission.
