Building Regulation Fees

Almost all works that require an Application for Building Regulations attract a fee.

The scale of fees is fixed by the Department of Finance and are consistent across all Local Authority Building Control Services in Northern Ireland.

The amount of fees payable with an application is dependent on the nature of the works that are to be undertaken.

The tables identify a fixed rate for certain domestic works and extensions, roof space conversions and installation/replacement of services.

When works do not encompass small buildings, extensions or conversions, the fee can be calculated on an estimated cost of the works. This estimated cost of works is based on the RICS Building Cost Information Service rates.

If the works proposed are to be used or are for the benefit of a person with a physical disability, the works are described as being exempt from Building Regulations Fees. This will require supporting written confirmation from an occupational therapist or your GP.

In small extensions under 20m2, the plan fee also covers any and all inspections subsequently carried out on site.

Where works do not encompass small buildings, extensions or conversions the fee can be calculated on an "estimated cost of works" basis.  The estimated cost should be based on a contractors cost to carry out such work.

If the works proposed are to provide an alteration or extension of a room for the benefit of a person with a physical disability, the works are deemed to be exempt from Building Regulations Fees. This will require supporting written confirmation from an occupational therapist or from your GP.

Full Plans Application

For a Full Plans Application, a Plan Fee is submitted together with the application form and two copies of relevant drawings.  The Plan fee covers Building Control assessment of the submitted drawings.  When the Building Control Surveyor commences the inspection of the works, an inspection fee is raised.  This takes the form of a one-off payment and covers all inspections carried out.

 

Building Notice Application

For a Building Notice Application, the fee is exactly the same as for a Full Plans submission.  However, the full fee is submitted with the application – there is no separation of payment to Plan Fee / Inspection Fee.

 

Building Regularisations

A fee amounting to 120% of the current plan and inspection fee for works carried out is payable on submission of a Regularisation application.
