Working in Caernarfon

In Caernarfon we cover LL55; we also cover Bangor, 8.3 miles away, and Holyhead.

Caernarfon gets the same process as anywhere else: a free survey at your home and a written, itemised quote. If you are replacing a failed electric shower in Caernarfon, we check whether the existing cable and circuit suit the new unit. If your Caernarfon bath has no shower over it, a thermostatic bar shower, screen and tiling can usually be added in a day or two.

Most of Gwynedd is supplied with soft water. If that holds for your street in Caernarfon, limescale on shower glass and heads builds up slowly and a squeegee after use is usually enough. Hardness varies street by street, so check the figure for your postcode with your water supplier.

What the job includes

A check of your hot-water system, water pressure and flow rate
Electrical connection by a qualified electrician, tested and certified
For an electric shower, a check of the consumer unit and whether a new dedicated circuit is needed
New pipework and isolation valves, plus a pump only where the system is gravity-fed from a cold tank

Decisions to make first

Exposed or concealed

An exposed bar valve fixes onto the tiles and is easy to service. A concealed valve sits in the wall for a cleaner look but needs careful setting-out and a plan for access.

Thermostatic mixer

Blends hot and cold from your system and holds the temperature steady when someone runs a tap. The usual choice with a combi or an unvented cylinder.

Rules that apply in Wales

In Wales, a new circuit for an electric shower is notifiable under the Welsh Part P, which covers more work than the English version. An unvented cylinder must be fitted by a G3-qualified installer.

Shower installation in Caernarfon: questions

How much does a new shower cost in Caernarfon?

A new shower in Caernarfon usually costs £400–£3,300 including VAT. The final figure comes down to what you choose and what we find at the survey; your written quote lists every item so you can see where the money goes.

Is the water hard in Caernarfon?

Who handles building control for a new shower in Caernarfon?

Building control for Caernarfon is handled by the local council or an approved inspector. If your job needs sign-off — for example a new circuit, new drainage or a new extractor where there was none — we tell you at the survey and handle the notification as part of the work.

How long does a new shower take?

Allow half a day to 3 days on site for most jobs, plus the lead time for products after you approve the quote. We give you a day-by-day plan before work starts in Caernarfon.

Can I fit a shower pump with a combi boiler?

No. A combi boiler takes its water from the mains, and connecting a pump directly to the mains supply is not allowed under the water fittings regulations. Shower pumps are only for gravity systems with a cold tank. If a combi shower is weak, the cause is usually the incoming flow, the boiler output or the head, not something a pump can fix.
