Can a Conservatory Be Built Over a Manhole Cover?

Choosing to add a conservatory to your home is one of the easiest ways to add both space and value to your property. They are one of the most popular types of home improvement and come in a range of different designs and styles. Here at Conservatories Etc, we are often asked questions by customers considering having a conservatory added to their home. One question we are increasingly being asked is: Can a conservatory be built over a manhole cover? The short answer is 'no, you can't'. However, it is possible for manhole covers to be moved.


Conservatory vs Manhole Cover


It actually isn’t possible to build anything over a manhole cover or any drain outlet. You can have drains and manhole covers moved, but this requires you contacting your local water services. You must also contact your local water authorities if you are planning to carry out any work within 3 metres of a manhole cover or drain.


When building near a manhole cover or drain, you will need to make sure the structure's foundation doesn’t add any load to the drain, this will allow for the drain to be relocated in the future. Should any weight be added to the drain, it could cause the drain to collapse. Before the work can take place, there needs to be an agreement with your local authority. Failure to declare the work to your local authority could cause major problems to your drains and could also land you in legal turmoil.
