THE ESTIMATING ANSWER
Estimate garden lighting installation by measuring the defined six low-voltage garden lights, separating product allowances from labour and setting out the work sequence and exclusions. This fictional Newcastle example uses 7 itemised lines totalling £3,342.97; its exact quantities and rates appear in the paired app PDF.
The worked job is six low-voltage garden lights in Newcastle. The written scope is: Install six selected low-voltage lights along one garden path with transformer, cable and a defined shallow route. Its matching itemised example shows how that description becomes quantities, allowances and a PDF. These figures are fictional inputs for learning the method, so check the real site, specification and supplier or subcontractor costs before quoting.
1. Define the measured job
Install six selected low-voltage lights along one garden path with transformer, cable and a defined shallow route. Count fixtures, measure cable run and identify transformer location and crossing points. Record the measurements and existing condition in the estimate before turning quantities into line items. The scope should make clear why this is a separate project from a broader renovation or maintenance quote.
Measure for this job: Count fixtures, measure cable run and identify transformer location and crossing points. Record the measured basis next to the relevant cost lines, since a room count, fitted length and purchased product quantity may each use a different unit.
2. Build a product and labour schedule
Separate fixtures, transformer and cable allowances. This example has 7 distinct lines, including garden lighting layout, light fitting allowance, transformer and timer allowance. Use actual supplier prices and labour inputs for a customer job; the displayed amounts are fictional document inputs.
Choose before pricing: Separate fixtures, transformer and cable allowances. Keep a named allowance when the selection is open, and replace it once the actual product and delivery terms are known.
3. Sequence the work and handoffs
Mock up light positions before trenching and confirm the power source. Show which task depends on access, a selected product or another trade. If that dependency is still open, label the price preliminary and identify the information needed before a firm quote.
Plan the handoffs: Mock up light positions before trenching and confirm the power source. State which stage needs access or inspection before the next can begin, especially if a concealed condition might stop the work.
4. Set a change boundary
Unknown buried services or a longer path changes route and quantity. The example excludes mains trench across public land, landscape rebuild or security system. Record the discovery, agree the revised work and update the estimate before adding it to the job.
Change trigger: Unknown buried services or a longer path changes route and quantity. If this happens, write down the revised quantity and responsibility before adding an item to the customer estimate.
Worked project calculation
The paired PDF has 7 cost lines. For example, Light fitting allowance is 6 each × £88.00 = £528.00; Cable and connector allowance is 54.9 metres × £10.50 = £576.45. Each amount is the stated quantity multiplied by its unit rate. Recheck whether a line describes installed work, a material purchase allowance or a distinct visit before changing its quantity.
| Work item | Quantity | Unit rate | Amount |
|---|---|---|---|
| Garden lighting layout | 1 lump sum | £144.00 | £144.00 |
| Light fitting allowance | 6 each | £88.00 | £528.00 |
| Transformer and timer allowance | 1 set | £272.00 | £272.00 |
| Cable and connector allowance | 54.9 metres | £10.50 | £576.45 |
| Shallow cable route labour | 45.7 metres | £23.60 | £1,078.52 |
| Light fitting and aiming | 6 each | £92.00 | £552.00 |
| Testing and reinstatement | 1 lump sum | £192.00 | £192.00 |
| Illustrative total | £3,342.97 | ||
Adding the 7 exact line amounts gives £3,342.97. The PDF uses a 0% tax input and no markup solely to display this arithmetic. Decide the appropriate tax, overhead and profit treatment for an actual job; the fictional rates are not local averages or price recommendations.
Scope and price boundaries
Install six selected low-voltage lights along one garden path with transformer, cable and a defined shallow route.
Outside this example: No mains trench across public land, landscape rebuild or security system.
The role in this brief is electrical contractor. Confirm who supplies the selected products, makes the site safe, removes waste and signs off the work. Where opening up reveals a different condition, document it and issue a revised scope and price rather than silently extending the base estimate. Also check access, drying or curing time, and the client handoff described in the work sequence.
