THE SHORT ANSWER
Estimate a sump pump replacement around the existing pit, discharge route, power and selected equipment. State what is tested and keep drainage-system redesign outside a simple replacement price.
Use this fictional one existing-pit pump replacement in York to plan the estimate. The agreed work is: Replace one pump in an accessible existing sump pit, using the existing suitable discharge route and power socket. Include pump allowance, removal, discharge fitting allowance, installation, operational check and disposal. No pit rebuild or new discharge routing. The matching sump pump replacement example and PDF shows the same inputs. These quantities and rates are teaching examples; use your own site measurements, product selections, supplier information and labour figures for a customer job.
1. Inspect the existing setup
Record pit access, pump type, discharge connection and socket condition. The example assumes the existing system can be reused without reconstruction.
2. Select the replacement equipment
State the chosen pump or a clearly labelled allowance. Verify the product against the actual installation and customer requirements rather than using a universal pump price.
3. Define connection work
List fittings and labour separately. A different discharge route, check-valve arrangement or electrical correction should be identified after inspection and quoted as added scope.
4. Record the operating check
Describe the limited operation check included at handoff and note any pre-existing drainage concerns that remain outside the pump replacement.
Calculate the measured lines
The PDF uses 7 separate items. For example, Pit access and protection is 1 lump sum × £92.00 = £92.00; Existing pump removal is 1 each × £104.00 = £104.00. Check that each unit describes the work being priced: area for a surface, metres for a run, and a count or defined lump sum for a discrete task. A material purchase allowance can differ from the installed quantity when product sizes, cuts or layout require it.
Adding the 7 rounded line amounts gives £968.00. The example PDF uses a 0% tax input and no markup; those settings do not determine how to price or treat an actual job. Do not copy the rates as a local price guide.
Check the scope before sending
- Identify pit and pump access.
- Confirm existing discharge and power assumptions.
- Select replacement product.
- Define check and disposal work.
Outside the base scope: No new pit, discharge-route change, electrical circuit repair, waterproofing work or guarantee against future water entry.
Confirm the site address, selected products, access, quantities, customer details and validity date. If opening the work reveals a different condition, record the change and update the relevant line before asking the customer to approve the revised work. Preview every page of the PDF so the written scope, line amounts and total tell the same story.
Common questions
Does a pump estimate include waterproofing?
Only if it is separately scoped. Replacing one pump does not price foundation or drainage repairs.
Should the discharge line be measured?
Yes if it is being changed. This example reuses a suitable existing route and only allows connection fittings.
