David Salisbury will always advise that you do the job properly. Just because it may be a small base for a conservatory or an orangery dies not mean that the base work should be done to any other than a properly compliant standard even if regulation approval is not required. Anyone wanting to carry out building work, which is subject to Building Regulations, is required by law to make sure it complies with the regulations and (with some exceptions) to use one of the two types of Building Control Service available, i.e.:
You will be charged for either service. The Building Control Service you select may offer advice before your work is started. The primary responsibility for achieving compliance with the regulations rests with the person carrying out the building work. So if you are carrying out the work personally the responsibility will be yours. If you are employing a builder the responsibility will usually be that firm’s - but you should confirm this position at the very beginning. You should also bear in mind that if you are the owner of the building, it is ultimately you who may be served with an enforcement notice if the work does not comply with the regulations. So it is important to choose your builder carefully.
You may need Building Regulations approval to check the integrity
of the structure or if you intend building over a drain or sewer. In
cases where it is obvious that you require building regulations, you
may well feel inclined to submit planning and building approval applications
at the same time. However there is a fee based on the value of the work,
so for complex projects it may be sensible to wait for planning consent
in case the scheme needs altering and a fresh application is required.
Building inspectors are practical chaps who you will find extremely
cooperative and we would recommend that you consult them at an early
stage. Building Regulations approval is unlikely to take more than a
month and you will often be given the go ahead verbally.
The regulations say you need to apply if:
You should not construct a conservatory where it will restrict ladder access to windows serving a room in the loft or a loft conversion, particularly if any of the windows are intended as a fire escape.
