If you do not follow the building control procedures set out for handling your building work or you carry out building work which does not comply with the requirements contained in the building regulations, you will have contravened the regulations.
Prosecution and enforcement notices
A local authority has a general duty to enforce the building regulations in its area and will seek to do so by informal means wherever possible. If informal enforcement does not achieve compliance with the regulations the local authority has two formal enforcement powers which it may use in appropriate cases.
First, if a person carrying out building work contravenes the Building Regulations, the local authority may prosecute them in the Magistrates' Court where an unlimited fine may be imposed (sections 35 and 35A of the Building Act 1984). Prosecution is possible up to two years after the completion of the offending work. This action will usually be taken against the person carrying out the work (builder, installer or main contractor).
Alternatively, or in addition, the local authority may serve an enforcement notice on the building owner requiring alteration or removal of work which contravenes the regulations (section 36 of the 1984 Act). If the owner does not comply with the notice the local authority has the power to undertake the work itself and recover the costs of doing so from the owner.
A section 36 enforcement notice cannot be served on you after the expiration of 12 months from the date of completion of the building work. A local authority also cannot take enforcement action under section 36 if the work which you have carried out is in accordance with your full plans application which the authority approved or failed to reject.
An appeal against a section 36 notice may be made to a Magistrates’ Court under section 102 of the Building Act.
Where an approved inspector is providing the building control service, the responsibility for checking that the building regulations are complied with during the course of your building work will lie with that inspector. They will usually do this by advising you.
However, approved inspectors do not have formal enforcement powers. In a situation where the inspector considers your building work does not comply with the building regulations and there is a refusal to bring it into compliance the inspector will cancel the initial notice. If no other approved inspector takes on the work, the building control function will automatically be taken on by your local authority. From this point on, your local authority will also have enforcement powers set out above where it considers this necessary.
Impact on Selling the Property
Notwithstanding the possibility of enforcement action, you should bear in mind that if the local authority or approved inspector considers that building work carried out does not comply with the building regulations and it is not rectified, no completion/final certificate will be issued and this is likely to come to light through a local land search enquiry when you wish to sell your property.
