Fees and charges

Depending on the size of the project, if you are submitting full plans, in most cases the fees are lower. This is because we can work systematically from the plans, and don’t need to be on site as much. Large or complex projects submitted as full plans have the benefit of a full plan assessment and are dealt with at a lower cost than building notices.

If you are not submitting full plans to us, you will need a building notice instead. These are generally more expensive, because we cannot work from the plans and need to make more on site visits.

Please submit the plan assessment or building notice fee with your application. Where applicable, we will invoice the inspection fee after work has started.

Fees are based on Building Control Charging Scheme and include VAT at 20%.

When looking for regularisation application costs, see building notice fees.

Consider us part of your team and involve us as early as possible.
