Latest review:
Extensions- 10 Jun 2026
Scott abandoned the work in the middle of winter after collecting several thousands of £££ in advance without completing or making safe (see attached photos). Due to poor quality of even the seemingly completed works (e.g inappropriate roof pitch/tiles/truss, improperly installed doors/windows & rising damp on internal plaster boards) the work was rejected by building control and I've had to pay another contractor again to remediate. Scott started the work on 15 Sept 2025 but abandoned site at the end of Feb 2026 with doors/windows/radiators only partially installed. Scott had originally committed to a 12 week build for completion before Christmas 2025 but the work dragged till end of Feb 2026 when the work was eventually abandoned. I have decided to take the matter to court after several unsuccessful attempts to get Scott back to finish the work or refund the cost of repairing / completing his work which is about £20k in addition to the roughly £70k I have already paid Scott.

What experience do you have with similar extensions in Swanley?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Swanley extension builder’s ability to deliver a result that meets your expectations.
