How to estimate an electrical job

1. 1.Walk the job and list every task

   Write down each piece of work as its own line: 'replace consumer unit', 'install 6 downlights in kitchen', 'add 2 double sockets in bedroom'. Separate lines make the estimate easy to price, easy for the customer to read, and easy to adjust when the scope changes.

2. 2.Count materials from the plan

   From the floor plan or a site visit, count every socket, switch, light point and metre of cable you'll need. A photo of the plan is enough — SparkQuote Pro's AI plan analysis can produce a rough, editable symbol count you then verify.

3. 3.Price materials from your own list

   Use your supplier's real prices, not generic figures. Keep a saved price list of the materials you use most so each estimate starts from numbers you trust. Anything you're unsure of gets marked as estimated, never guessed silently.

4. 4.Estimate labor hours honestly

   Give each task an hour range based on similar jobs you've done, then use the midpoint. Multiply by your hourly rate. First-fix on a new build is faster per point than a rewire in an occupied house — adjust for access, ceilings and wall types.

5. 5.Add markup, tax and a valid-until date

   Apply your material markup and tax rate, then set how long the quote is valid — 30 days is common. A clear expiry date protects you from price increases and gives the customer a reason to decide.

• Send the estimate the same day you see the job — speed wins work.
• State what's NOT included (decoration, patching, permits) to avoid disputes.
• Review every line before sending; the customer sees the details, not your draft.
