Smart home technology in listed buildings and period properties
Older homes need a more careful approach. Here is how we add modern control while protecting the fabric and character of the building.

This guide is general information, not legal advice. Always check with your local planning authority before work starts on a listed building.
Listed building consent
Historic England explains that if you want to alter a listed building in a way that affects its character as a building of special architectural or historic interest, you must first apply for listed building consent from your local planning authority (Historic England: Listed Building Consent). This applies to the inside of the building as well as the outside.
Historic England also publishes advice on installing building services such as electrical wiring in historic buildings in ways that minimise permanent damage (Historic England: installing services). If in doubt, speak to your council's conservation officer early.
How we approach older properties
- Wireless first. Retrofit devices that sit behind existing switches or in the back box avoid chasing new cable runs through historic walls.
- No neutral? No problem. Many older homes have no neutral wire at the switch. We use devices designed for that, as in our Uxbridge period home.
- Thick walls. Stone and solid walls block wireless signals, so we plan the network and the wireless mesh carefully, as we did in our Grade II listed farmhouse in Seaham.
- Keep the look. Switch plates, sensors and panels are chosen to suit the interior, and hardware is hidden wherever it can be.
- Reversible where possible. We favour installations that can be removed later without lasting damage.
What works well in period homes
Smart lighting, room-by-room heating, discreet security and gate or door access are all achievable without major works. Whole-home audio and wired shading are harder and depend on what the building allows.
Common questions
Do I need listed building consent for smart lighting?
It depends on the work. Changes that affect the character of the building may need consent. Check with your local planning authority before work starts.
Can you work with our conservation officer?
Yes. We can explain the proposed methods so you can discuss them with your local authority.

How much does a smart home cost in the UK?
Real figures from our own projects, what pushes the price up or down, and what you should budget for after installation.
When should you plan a smart home in a new build or renovation?
Before first fix. Cabling decisions are cheap while walls are open and expensive afterwards, so the design should be settled before the electrician starts.
Smart home wiring checklist: what to cable during a renovation
If the walls are open, cable generously. Cable is cheap, labour to add it later is not. This checklist covers what we ask for on every renovation.
