Seven renovation planning mistakes you can avoid

1–2. Comparing totals and overlooking preparation

A short quotation can hide major differences. Check whether removal, protection, substrate repairs, waste disposal and making good are included. Ask the contractor to separate quantities and assumptions so the price reflects the same job.

Do not assume the existing base is suitable just because the visible finish looks flat. Have the team review the condition and identify what can be confirmed before work and what will remain uncertain until access is available. Agree how any discovery will be documented and priced.

3–4. Choosing late and leaving supply unclear

A design image is not a procurement list. Record product references, dimensions and availability before committing to dates. Include small but consequential items such as door hardware, trims, access panels and lighting controls.

Where you buy an item yourself, agree who checks suitability, accepts delivery, stores it, installs it and deals with damage or missing parts. Client supply does not remove the need for coordination. Keep receipts and product information with the project records.

5. Approving changes only in conversation

Moving one fitting may affect more than its visible position. Ask for a written description of the change, its cost and its effect on completed work and programme. Accept the change through the agreed process before execution.

A simple change log can list the date, room, requested change, price, time effect and approval. It is easier to manage a series of small choices this way than to reconstruct them at handover.

6. Treating access as someone else’s problem

Confirm permitted work times, lift booking, delivery size limits, storage and waste routes with the property manager. For a G+1 townhouse, include protection and safe circulation between levels. If the home stays occupied, ask which areas and services will remain usable at each stage.

7. Leaving no space for final checks

Make the inspection and snag-closing process part of the plan. Compare each room with the agreed scope and samples; distinguish an unfinished item from a newly requested upgrade. A dated list gives the team a clear route to closure.

• One written scope shared by everyone quoting.
• Preparation and unknown conditions identified.
• Selections and supplier dates recorded.
• Supply and installation responsibilities assigned.
• Written change approval process agreed.
• Building access and protection planned.
• Handover and snag closure included.
