Electrical work in a townhouse
Townhouses pack a family home into a narrow footprint. That shapes where cables can go and how much room the board has for anything new.
A townhouse usually has a single board, often in a utility area or under the stairs, with most ways already used. Adding circuits for an extra split unit, an outdoor kitchen or an EV charger can run into the limit of spare space or the supply’s capacity. Cable routes are tight because rooms are stacked and some walls are shared with neighbours.
Property guides describe how electrical work changes with the type of building it happens in.
Shared walls mean chasing or drilling has to be careful: cables and pipes from either side may be close, and noise affects the next house. Small gardens are often paved, so new outdoor supplies need routes that avoid lifting large areas. Community rules may also govern external fittings, visible cable runs and working hours.
01In short
The points that matter most
Little spare board space
New circuits may need a larger board or a small sub-board.
Shared walls
Drilling and chasing need care on party walls.
Community rules
External changes and working times may be restricted.
02Detail
Common townhouse requests
Patio and courtyard lighting
Wall lights and low-level fittings with cable routes that avoid lifting paving.
Extra sockets in small rooms
Placed where furniture actually goes, often in surface trunking where walls are shared.
Roof-terrace supplies
Lights and sockets for terraces, with weatherproof fittings and sensible routes up through the house.
Board capacity checks
Confirming spare ways and supply capacity before planning new loads.
03Checklist
Before work starts
Check community rules
Ask the community management about external fittings and working hours.
Count spare ways
Photograph the board so spare space can be seen.
Tell the neighbours
Drilling on a shared wall is loud on their side too.
04Questions
Questions people ask
- Can I add an EV charger to a townhouse?
- Often, subject to supply capacity, board space, a cable route to the parking space and community approval.
- Why is there so little space in my board?
- Townhouse boards are usually sized for the original layout, and additions use up spare ways quickly.
- Is it safe to drill into a party wall?
- With care. Cable detection and shallow fixings reduce the risk of hitting services on either side.
- Can outdoor lights be added without lifting paving?
- Often, by running cables along walls or under edging rather than across the patio.
