EXAMPLE AT A GLANCE
This fictional Birmingham interconnected smoke alarm installation project has 7 itemised lines and an illustrative £1,608.00 total. The app-exported PDF, first-page preview, measurement basis, scope boundaries and matching UK estimating guide let you inspect every quantity and rate.
What this example covers
This fictional job is set in Birmingham and concerns four alarm positions. Install four selected interconnected smoke alarms at agreed positions using suitable existing power or approved selected equipment. The estimate is a bounded document: the customer should be able to compare the described work with its measured lines, product allowances and exclusions. The matching UK guide explains how to prepare those inputs.

Itemised interconnected smoke alarm installation example
These 7 lines reproduce the app-exported PDF exactly. The largest is Alarm fitting labour at £464.00; this is one fictional component, not a typical price. Read each quantity with its unit: area, length, time, count and lump sum describe different work and must not be interchanged.
| Work item | Quantity | Unit rate | Amount |
|---|---|---|---|
| Position survey and plan | 1 lump sum | £168.00 | £168.00 |
| Alarm unit allowance | 4 each | £76.00 | £304.00 |
| Bases and connection parts | 1 set | £144.00 | £144.00 |
| Cable routing allowance | 1 lump sum | £256.00 | £256.00 |
| Alarm fitting labour | 4 each | £116.00 | £464.00 |
| Interconnection test | 1 lump sum | £192.00 | £192.00 |
| Handoff labels and clean-up | 1 lump sum | £80.00 | £80.00 |
| Illustrative total | £1,608.00 | ||
The table separates the named product or material allowances from labour and site tasks wherever the scope needs that distinction. Before replacing a rate, check whether the product allowance includes delivery, waste, fixings and the selected specification.
How the total is calculated
Alarm unit allowance is 4 each × £76.00 = £304.00. Alarm fitting labour is 4 each × £116.00 = £464.00. The other lines follow the same calculation and sum to £1,608.00. Each fixture line lands on an exact penny, so the native PDF total equals the sum of the displayed line amounts.
Measurement to check: Count rooms and alarm positions, record ceiling construction and interconnection route. Selection to check: Identify alarm units, bases and interconnection components separately. The 0% tax field and zero markup are example document inputs, not an instruction for a live quote. Decide the correct settings for your own business and job.
Assumptions and exclusions
Confirm the required local design with a qualified installer before setting the positions.
Outside this stated scope: No whole-building fire-system design, panel replacement or guarantee of regulatory compliance without review.
A missing circuit or inaccessible route changes installation method. A changed condition should lead to a newly measured quantity, explicit revised allowance or separately agreed task. Keep the customer informed of which figure changed and why before producing another PDF.
