About Our Electric Shower Installation Service in Merton
Most houses can take an electric shower, but not every house can take the one you have picked. The bigger the shower, the more it pulls, and the question is whether your fuse box has a spare way and your supply can carry it. We check that before quoting, not after.
A shower needs its own circuit, its own cable and a pull-cord isolator on the ceiling. Swapping like for like, the existing cable is usually fine and it is a half-day job. Going up a size, say 8.5 kW to 10.5 kW, normally means a thicker cable all the way back to the fuse box. That is what turns a morning into a day.
Either way the job finishes the same: the shower gets tested properly and you get an Electrical Installation Certificate for it.
Section 701 of BS 7671 puts the shower in Zone 1, so 30 mA RCD protection is required on every circuit in the bathroom. We fit an RCBO per circuit, so a fault on the shower leaves your lighting on. A new shower circuit is notifiable under Part P twice over: it is a new circuit, and it is work in a special location. Norspark is NAPIT registered, so we self-certify the work and issue the Building Regulations compliance certificate ourselves. No separate building control application, and no fee for one.

Frequently Asked Questions
Can I go from an 8.5 kW shower to a 10.5 kW one using the existing cable?
Sometimes. A 10.5 kW shower pulls around 46 A against roughly 37 A for an 8.5 kW, so a 6 mm2 cable usually has to be replaced. Fitting a larger breaker to an undersized cable is a C1 defect, immediately dangerous, and it is one of the more common things we find on a shower circuit. We measure the cable before quoting the upgrade.
Will a more powerful shower fix weak water pressure?
No. The kW rating controls how much the water is heated, not the pressure. Flow is set by your incoming cold mains. A higher rated shower gives you a warmer flow at the same rate, or the same warmth at a higher rate, and it will not improve a weak mains supply.
Why does the shower need its own circuit and a pull cord?
The load is too high to share, so it runs from its own way in the consumer unit rather than off a ring or the cooker circuit. The pull cord is the local double-pole isolation needed to work on the shower safely. A wall switch is fine instead, as long as it sits outside the bathroom zones.
I have been told my new shower needs bonding work. Is that necessary?
It depends what is already there. Supplementary bonding in the bathroom can be omitted where all three of these hold: every circuit in the room has 30 mA RCD protection, disconnection times are met, and main protective bonding to the incoming water and gas is in place and correctly sized. In older houses that last one is often missing or undersized, and that is the part that has to be put right.
