Factors impacting the cost of a glass conservatory

Factor 1: The dimensions of the conservatory

The dimensions exert the greatest influence on the total price tag of a glass conservatory. As a starting point, you can count on about 870 GBP per square meter for a glass conservatory. From an area of 30 square meters, the price per square meter will decrease. This has to do with the fact that the fixed costs will not increase anymore. It is always possible to engage in a conversation with a conservatory specialist to determine which size of conservatory is best suited to your expectations and the property you have.

Factor 2: The type of glass

When you choose to invest in a glass conservatory, it is obvious that it consists mostly of glass. It is therefore no more than normal that the type of glass used will also have a significant impact on the overall price tag. For high-end glass, a cost of about 4 GBP per square meter applies. If you choose HR ++ glass, this cost rises to about 13-17.5 GBP per square meter. Do you only want to enjoy the best of the best? Then an investment in HR +++ glass with an average cost tag of between 48-52 GBP per square meter is recommended.

Factor 3: Additional materials

In spite of the fact that a glass conservatory obviously consists for the most part of glass, other materials are also used. In this respect, it is always important to note that the price of these materials can also have a significant impact on the total price tag. For example, for a plastic conservatory, you can count on an average cost of between 11000 and 12000 GBP. If wood is used, this price may be slightly higher, but the difference will be minimal. The most expensive is choosing aluminium, which means that the price tag soon goes up to 13000 GBP or more.
