Is my extension ready for a stage payment?

Start with what was agreed

Look at your contract, quotation or payment schedule and find the wording for the stage in question. If the wording is short, it may need to be turned into a clearer list of criteria before the next stage.

A sensible checklist for a watertight stage

As an illustration only, a watertight milestone might be defined as:

• Primary roof structure complete
• Roof covering installed
• Membranes installed where applicable
• Flashings completed
• Rooflights installed where included
• External windows and doors installed where included
• Openings appropriately weatherproofed
• Relevant inspection evidence available where applicable

If you are not sure

Independent milestone verification gives you an evidence-based record rather than an opinion exchanged over text messages. Remote verification starts from £99 and reviews timestamped photographs, video, drawings and other supporting documents against the agreed criteria. Site verification starts from £249 where physical attendance is appropriate.

A verification result is not a survey, a warranty, or a judgement about the overall quality of the project. It records whether the agreed criteria for that milestone appear to have been satisfied on the evidence reviewed.
