Construction Management Plan Cost & Timelines

The cost of a CMP depends on the scale and complexity of the project, the borough involved and whether supporting work such as swept path analysis or noise surveys is needed. A CMP for a single-dwelling extension is priced very differently from a multi-phased development. CMP Construct provides a free, no-obligation quotation within 48 hours of an enquiry. Send us the property address and planning details and we will confirm a fixed price for your project.

The main cost drivers are: the size and duration of the build; whether demolition or basement construction is involved; the constraints of the site and surrounding streets; the specific borough’s requirements and preferred format; and any supporting assessments the council asks for, such as swept path analysis or noise surveys. When you request a quotation we identify exactly what your planning condition requires, so you only pay for the documents you actually need.

Yes. Quotations are free, provided within 48 hours of an enquiry, and carry no obligation. The most useful details to include are the full property address, the service you need (CMP, CTMP or CLP), the planning condition number if you have one, and a link to the planning application.

Preparing the document is the quick part: most straightforward CMPs are drafted within 7-10 working days of receiving project information. Council review time varies by borough: discharge-of-condition applications have a statutory determination target, but busy planning departments can take longer, so it pays to commission the CMP as early as possible rather than waiting until you are ready to start on site.

Yes. A rejected or under-specified CMP is one of the most common causes of delay between planning approval and starting on site, because work cannot legally begin until the condition is discharged. A plan written by experienced construction professionals, in the format the borough expects, substantially reduces the risk of officer push-back and resubmission cycles.
