Costs reflect mainland‑UK averages in mid‑2025 and already include 20 % VAT.

Typical duration: 2–4 hours for a like‑for‑like swap.
Can extend to a full day when:
- worktop or vanity needs cutting or strengthening;
- pipework is being rerouted;
- tiles/worktop need patching and curing time;
- access is restricted (e.g., high‑rise flats with long carry‑distance).

Is your quote fixed‑price or day‑rate, and what does it include?
Will you supply the sink and taps, or should I purchase them?
Do you foresee any cutting, retiling or additional carpentry?
How will you handle disposal of the old sink and packaging?
What guarantee do you give on workmanship and supplied materials?
Are isolation valves being fitted for future maintenance?
Do you carry Public Liability insurance, and are you WaterSafe or CIPHE registered?

Clear access & parking: reserve a space close to the door.
Confirm shut‑off valve location and that it turns freely.
Check worktop / vanity suitability for new sink size & weight.
Advise of any working‑at‑height or apartment restrictions (lift access, stair protection).
Confirm waste‑disposal plan (skip bag, council permit).
Have finishes on site (tiles, silicone colour) to avoid return visits.
