AV setup budget
Prefilled amounts are hypothetical examples. Enter your own complete GBP quote and a reserve you choose to model.
(Equipment +accessories/delivery +work) ×(1+reserve/100). Reserve is an assumption, not a quoted charge. No future prices, repairs or performance are forecast.Cabinet width allowance
Use the exact equipment and furniture measurements. Side-clearance input must come from the applicable instructions or remain an explicit assumption.
Available width −equipment width −2×side clearance. A nonnegative result does not certify depth, height, airflow, load-bearing capacity, stability or safe installation. The 50 mm default is hypothetical.Projector throw estimate
Use a documented ratio for your exact model or keep the input hypothetical. The 1.2 default is an example, not an Epson specification.
Image width ×throw ratio. Use the manufacturer’s exact tables and conditions for the actual decision. This excludes projector body depth, lens shift, offsets, ventilation, distortion correction and any mounting or electrical assessment.
