EXAMPLE AT A GLANCE
This fictional Oxford heat recovery ventilation installation project has 7 itemised lines and an illustrative £9,143.28 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 Oxford and concerns one small dwelling ventilation unit. Install a selected heat-recovery ventilation unit with defined supply and extract points in an accessible area, subject to system design. 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 heat recovery ventilation installation example
These 7 lines reproduce the app-exported PDF exactly. The largest is Duct and insulation allowance at £2,591.28; 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 |
|---|---|---|---|
| Ventilation design allowance | 1 lump sum | £520.00 | £520.00 |
| HRV unit allowance | 1 each | £2,080.00 | £2,080.00 |
| Duct and insulation allowance | 54.9 metres | £47.20 | £2,591.28 |
| Supply and extract terminals | 6 each | £108.00 | £648.00 |
| Duct installation labour | 30 hours | £76.00 | £2,280.00 |
| Power and control allowance | 1 lump sum | £576.00 | £576.00 |
| Airflow balance and handoff | 1 lump sum | £448.00 | £448.00 |
| Illustrative total | £9,143.28 | ||
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
Duct and insulation allowance is 54.9 metres × £47.20 = £2,591.28. Supply and extract terminals is 6 each × £108.00 = £648.00. The other lines follow the same calculation and sum to £9,143.28. 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 terminals, measure duct routes and available plant space, and record condensate and power needs. Selection to check: Separate unit, duct, terminals and controls from commissioning. 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 airflow design and duct routes before cutting openings.
Outside this stated scope: No whole-house retrofit, structural openings or unreviewed regulatory certification.
Concealed route conflicts or inadequate plant space change layout and labour. 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.
