Loft Conversions

Table A, Category 5 of our General Guide to Charges specifies the minimum Plan and Inspection Charge for a loft conversion. This correlates to an estimated cost of work of £35,000. Where the estimated cost of work exceeds £35,000, Table C, Category14 should be used to refer to the appropriate Plan and Inspection Charge. Our General Guide to Charges is available from our Charges page.

Garage Conversions

Table A, Category 6 of our General Guide to Charges specifies the minimum charge for a single garage conversion based on an estimated cost of works of £10000. Where the estimated cost of work exceeds £10000 i.e. double garage, please refer to Table C, Schedule 14 on our Scheme of Charges for the appropriate charge. Please see our Charges page for the General Guide to Charges.

For comparison purposes, the estimated cost of works for particular building uses, will be determined by the Royal Institute of Chartered Surveyors Building Cost Information Service.

This provides an indication of the construction costs where a detailed estimate cannot be provided. These rates should be used for calculating Building Regulation Charges. These rates are regularly reviewed and updated. Please see download below for latest information.
