What affects the cost of smart home?
- Location: London and the South East are 15–40% more expensive than the national average.
- Size and complexity: Larger or more complex jobs cost proportionally more.
- Material quality: Budget, mid-range and premium specifications can vary by 2–3x.
- Time of year: Demand peaks in spring and summer — book in winter for better availability and pricing.
- Access: Difficult access (scaffolding, confined spaces) adds to labour costs.
How to save money on smart home
- Get at least 3 quotes from different tradespeople.
- Book during quieter periods (January–March for most trades).
- Be flexible on start dates — tradespeople often discount for convenient scheduling.
- Supply your own materials where possible (but confirm with your tradesperson first).
- Combine jobs — having multiple trades on site at once can reduce overall costs.
How to find a good tradesperson
Always check reviews on Checkatrade, Rated People or MyBuilder. Ask for references from recent similar jobs. Ensure they are appropriately qualified and insured. Never pay the full amount upfront — a deposit of 10–25% is standard.
