THE SHORT ANSWER
Break the renovation into measurable surfaces, countable fittings, trade labour and clearly named allowances. Record the scope and exclusions, then check that every line and the final total match the PDF you intend to share.
The worked example is a fictional 40 sq m interior renovation in Manchester. Its matching sample page and two-page PDF come from an actual Estimates app export. The figures illustrate a method of presenting work; they are not regional rates or a proposal for a real job.
Define what “interior renovation” includes.
Walk the space and list the areas affected. For each one, note existing condition, removal and preparation, new construction, finishes and handover work. Confirm whether the customer has chosen the materials, and record any condition that remains hidden until work starts.
The Manchester sample states framing, plasterboard, carpet, lighting and a wet bar in its brief scope. The PDF adds item lines for electrical installation, plumbing rough-in, paint, doors and trim, clean-up and allowances. A broad project title does not automatically include structural changes, damp remediation or work beyond the listed electrical and plumbing tasks. Describe those separately if they are part of the actual job.
Measure surfaces and fittings by work type.
The 40 sq m in the project name describes the interior project; it is not every item’s quantity. The PDF has 74 sq m of plasterboard installation, 74 sq m of paint and primer, and 37 sq m of carpet. These bases can differ because walls and floors are different surfaces and not every part of the floor must receive the same finish.
| Item | Example calculation | Amount |
|---|---|---|
| Plasterboard installation | 74 sq m × £21.62 | £1,599.88 |
| Paint & primer | 74 sq m × £12.97 | £959.78 |
| Carpet installation | 37 sq m × £38.92 | £1,440.04 |
Measure your own wall faces, openings and finished floor areas. State whether your quantity already includes any material allowance so it is not added again elsewhere. Check the product specification and site conditions before choosing the rate for each line.
Keep separate trades and fittings visible.
The sample shows ten hours of electrical installation at £56 (£560) and eight recessed lighting fixtures at £40 (£320). These are distinct descriptions. Before quoting a real job, confirm exactly what the labour line covers and whether fitting supply or installation would otherwise be counted twice.
It also shows four doors and trim units, a wet bar plumbing rough-in, wet bar cabinets and countertop, and framing and insulation. The lump sums need a written specification if a customer is to know the finish or extent being allowed for. A line labelled “wet bar” alone would leave too much open to interpretation.
Name allowances and unresolved decisions.
Two sample lines are expressly allowances: £800 for contingency and £320 labelled “Permits & inspections allowance” in the source PDF. Keep that original wording in mind when reading the example, but write the line for your own UK job according to the permissions or checks that genuinely apply. Agree how unused or additional allowance amounts will be handled in the actual project.
A contingency line is not a substitute for investigating known defects or describing excluded work. Record any assumptions about access, existing services, substrate condition, chosen finishes and waste removal. If one changes, revise the affected work and total.
Check the complete PDF, not just the total.
The 12 example lines add to £9,559.70. The PDF displays Tax 0%: £0.00, so its total is also £9,559.70. That is the sample’s setting, not guidance for your own tax calculation. Confirm the right treatment for your business and project.
Read both pages: business and customer details, scope, every amount, notes and dates. The sample’s note explicitly asks readers to review quantities, local rates and applicable tax before sharing. Use your own measured quantities, checked costs and a revised scope before sending your document.
Common questions.
Why is the plasterboard area larger than the project area?
The project area describes the space in plan. Plasterboard is measured on the surfaces being boarded. The example does not provide detailed drawings, so do not treat its 74 sq m as a formula for every 40 sq m room.
Can I reuse the PDF’s pound amounts?
Use them to check the sample arithmetic only. They are fictional example inputs. Your estimate needs actual measurements, supplier and trade costs, specifications and the scope agreed with your customer.
