THE ESTIMATING ANSWER
Estimate utility sink installation by measuring the defined one new utility-room sink, separating product allowances from labour and setting out the work sequence and exclusions. This fictional Exeter example uses 7 itemised lines totalling £1,348.00; its exact quantities and rates appear in the paired app PDF.
The worked job is one new utility-room sink in Exeter. The written scope is: Install one selected utility sink near existing suitable water and drain services, with tap, trap and wall or floor support. 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 one selected utility sink near existing suitable water and drain services, with tap, trap and wall or floor support. Measure sink footprint, service route, fixing support and working clearance. 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 sink footprint, service route, fixing support and working clearance. 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 sink, tap and connection materials from fit-out labour. This example has 7 distinct lines, including site measurement and protection, sink product allowance, tap allowance. Use actual supplier prices and labour inputs for a customer job; the displayed amounts are fictional document inputs.
Choose before pricing: Separate sink, tap and connection materials from fit-out 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
Confirm drain fall and shutoff before fixing the sink. 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: Confirm drain fall and shutoff before fixing the sink. 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
Hidden pipework or weak wall support can change the mounting method. The example excludes new room drainage, cabinet fitout or floor repair. Record the discovery, agree the revised work and update the estimate before adding it to the job.
Change trigger: Hidden pipework or weak wall support can change the mounting method. 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, Site measurement and protection is 1 lump sum × £108.00 = £108.00; Sink product allowance is 1 each × £312.00 = £312.00. 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 measurement and protection | 1 lump sum | £108.00 | £108.00 |
| Sink product allowance | 1 each | £312.00 | £312.00 |
| Tap allowance | 1 each | £144.00 | £144.00 |
| Waste and supply fittings | 1 lump sum | £176.00 | £176.00 |
| Support and mounting | 1 lump sum | £224.00 | £224.00 |
| Water and drain connection | 1 lump sum | £288.00 | £288.00 |
| Leak check and clean-up | 1 lump sum | £96.00 | £96.00 |
| Illustrative total | £1,348.00 | ||
Adding the 7 exact line amounts gives £1,348.00. 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 one selected utility sink near existing suitable water and drain services, with tap, trap and wall or floor support.
Outside this example: No new room drainage, cabinet fitout or floor repair.
The role in this brief is plumbing 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.
