• Age and condition of the property – Older homes often need more work, such as rewiring, replumbing or damp proofing.
• Location within London – Central London tends to be more expensive than outer boroughs due to higher labour and material costs.
• Quality of finishes – High-end kitchens, bathrooms and bespoke fittings will add to the total cost.
