The Service
What Is Electric Shower Installation?
Electric shower installation covers fitting a new or replacement electric shower and its dedicated high-current circuit — the right cable, a double-pole isolator, an RCD-protected connection and, in a bathroom, correct zoning and IP rating.
Because showers draw a lot of power (often 8.5–10.5 kW), the cable, protective device and isolator must all be correctly rated. An undersized cable or protection device is a serious fire risk.

Why It Matters
Why Professional Electrical Work Matters
Electric showers are among the highest-load appliances in a home. An undersized cable, wrong protective device or missing isolator is a real fire and shock risk in a wet environment.
Showers are a special location under the wiring regulations, so the work is notifiable, must be RCD-protected, and must be carried out and certified by a competent person.
Costs & Pricing
Costs & What Affects Pricing
Pricing for electrical work depends on the job. Here are the factors that typically affect the cost of this service.
- The power rating of the shower (kW)
- The cable run length and whether it needs upgrading
- Whether the consumer unit needs an upgrade for the load
- Whether an isolator needs fitting
- Access for routing the cable
A like-for-like shower replacement is usually straightforward; a new or higher-power shower may need a new cable and isolator. Tell us what's involved.
