If your project is likely to extend over one month it is reasonable, and probably desirable, to make interim payments. If you do, you
may be able to negotiate a better price, but this must be agreed at tender stage. You could be asked for stage payment at completion intervals
such as:
- Foundations drainage and ground slab
- Brickwork to roof and windows
- Roof complete and services in
- Finishes and completion
It is reasonable to hold back retention money, but only if agreed at a time of tender, 5% of each stage is
normal. Be sure to agree a formula for what happens if work is completed out of the expected sequence. You
can ask the contractor for a cash flow projection and if possible have it professionally verified.
Hold the contractor to the agreed programme and politely chase if the schedule is falling behind.
Record progress photographically and to avoid any time dispute include the day's newspaper in the
foreground.
In general: -
- Do not lend or borrow tools or ladders
- Be certain who is responsible for site security and locking up
- Make sure that any warranties for major appliances are in your name
