THE ESTIMATING ANSWER
Estimate outdoor socket installation by measuring the defined two garden power points, separating product allowances from labour and setting out the work sequence and exclusions. This fictional Nottingham example uses 7 itemised lines totalling £2,337.60; its exact quantities and rates appear in the paired app PDF.
The worked job is two garden power points in Nottingham. The written scope is: Install two weatherproof outdoor power points on an accessible wall using a confirmed suitable supply 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 two weatherproof outdoor power points on an accessible wall using a confirmed suitable supply route. Measure route length, mounting positions, exposure and cable protection requirements. 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 route length, mounting positions, exposure and cable protection requirements. 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 enclosures, cable and protective devices from fitting labour. This example has 7 distinct lines, including supply and route survey, weatherproof socket 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 enclosures, cable and protective devices from fitting 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 confirm supply suitability and local installation requirements. 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 confirm supply suitability and local installation requirements. 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
An unsuitable source circuit or longer route changes materials and labour. The example excludes trench, new consumer unit or power to detached buildings. Record the discovery, agree the revised work and update the estimate before adding it to the job.
Change trigger: An unsuitable source circuit or longer route changes materials and labour. 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, Weatherproof socket allowance is 2 each × £124.00 = £248.00; Cable and containment allowance is 16.8 metres × £42.00 = £705.60. 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 |
|---|---|---|---|
| Supply and route survey | 1 lump sum | £148.00 | £148.00 |
| Weatherproof socket allowance | 2 each | £124.00 | £248.00 |
| Cable and containment allowance | 16.8 metres | £42.00 | £705.60 |
| Protective fittings allowance | 1 lump sum | £192.00 | £192.00 |
| Cable routing labour | 7 hours | £80.00 | £560.00 |
| Socket fitting | 2 each | £152.00 | £304.00 |
| Testing and labelling | 1 lump sum | £180.00 | £180.00 |
| Illustrative total | £2,337.60 | ||
Adding the 7 exact line amounts gives £2,337.60. 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 two weatherproof outdoor power points on an accessible wall using a confirmed suitable supply route.
Outside this example: No trench, new consumer unit or power to detached buildings.
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.
