THE ESTIMATING ANSWER
Estimate home EV charger installation by measuring the defined one residential charging point, separating product allowances from labour and setting out the work sequence and exclusions. This fictional Manchester example uses 7 itemised lines totalling £3,335.55; its exact quantities and rates appear in the paired app PDF.
The worked job is one residential charging point in Manchester. The written scope is: Install a selected home EV charger at a confirmed parking position with a defined cable route and existing-service assessment. 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 a selected home EV charger at a confirmed parking position with a defined cable route and existing-service assessment. Measure cable route, mounting position, consumer unit capacity information and parking access before proposing equipment. 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: Measure cable route, mounting position, consumer unit capacity information and parking access before proposing equipment. 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 charger, cable and protective device allowances from installation labour. This example has 7 distinct lines, including site and load assessment allowance, charger unit allowance, cable and containment allowance. Use actual supplier prices and labour inputs for a customer job; the displayed amounts are fictional document inputs.
Choose before pricing: Separate charger, cable and protective device allowances from installation labour. 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
A qualified installer must verify service and protective-device suitability before work. 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: A qualified installer must verify service and protective-device suitability before work. 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
Insufficient capacity or a longer concealed route requires a revised design. The example excludes service upgrade, trench across public land or utility-provider work. Record the discovery, agree the revised work and update the estimate before adding it to the job.
Change trigger: Insufficient capacity or a longer concealed route requires a revised design. 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, Cable and containment allowance is 19.8 metres × £47.25 = £935.55; Cable routing labour is 10 hours × £84.00 = £840.00. 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 |
|---|---|---|---|
| Site and load assessment allowance | 1 lump sum | £200.00 | £200.00 |
| Charger unit allowance | 1 each | £544.00 | £544.00 |
| Cable and containment allowance | 19.8 metres | £47.25 | £935.55 |
| Protective device allowance | 1 set | £256.00 | £256.00 |
| Cable routing labour | 10 hours | £84.00 | £840.00 |
| Mount and connect charger | 1 lump sum | £336.00 | £336.00 |
| Testing and documentation | 1 lump sum | £224.00 | £224.00 |
| Illustrative total | £3,335.55 | ||
Adding the 7 exact line amounts gives £3,335.55. 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 a selected home EV charger at a confirmed parking position with a defined cable route and existing-service assessment.
Outside this example: No service upgrade, trench across public land or utility-provider work.
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.
