100% Brechin Local.
I served as a Retained Firefighter with Brechin Fire Service and a Royal Air Force Electrical Engineer. I've attended too many house fires caused by improper hot tub wiring.
Hot tubs mix water and high current—a lethal combination if installed incorrectly. When I wire your spa, every connection is sealed, every earth is tested, and every circuit is RCD protected. Your family's safety is non-negotiable.

Hot Tub Safety Requirements
Hot tubs are classified as special locations under BS 7671. Here's what makes them different from standard outdoor electrics.
RCD
Protection
Hot tub circuits must be protected by a 30mA RCD. This trips in 40 milliseconds if water enters the electrics, preventing fatal shocks.
Local
Isolation
A rotary isolator must be within 2 meters of the hot tub. This allows you to kill power instantly in an emergency.
IP65
Rating
All hot tub electrical equipment must be IP65 minimum—fully sealed against jets of water from every angle.
SWA
Cable
Standard twin & earth cable is illegal outdoors. We use armoured cable (SWA) that's rodent-proof and weatherproof.
Cable Size Matters
The further your hot tub is from your fuse box, the thicker the cable needs to be.
Up to 20 Meters
6mm² SWA
Standard for most gardens
20-40 Meters
10mm² SWA
Required for long cable runs
We Calculate: Voltage Drop + Load
PopularHot Tub Installation Locations in Brechin
We wire hot tubs in back gardens, decking areas, and patios across Angus.
Decking & Patio Area
We install weatherproof isolators on decking posts or external walls, with SWA cable buried under the deck structure.
Remote Back Garden
Long cable runs across your lawn. We dig trenches to regulation depth and use 10mm² SWA to handle voltage drop over distance.
Inside Summer House
Indoor hot tubs require additional ventilation extraction. We install dedicated circuits with humidity-rated equipment.
Holiday Lodges
Commercial hot tub installations for rental properties. We provide certification for insurance and building control sign-off.

Safety Warning: Water + High Current = Lethal
Hot tubs draw 13-32A continuously—enough to kill instantly if wiring is improper. Extension leads, outdoor plug strips, and DIY connections are illegal and deadly.
We install to BS 7671 Section 702 (Swimming Pools & Hot Tubs) with full certification. Your insurance will not pay out if your hot tub isn't Part P compliant.
OurHot Tub Wiring Installation Process
From site survey to final certification, we handle everything safely and efficiently.
Site Survey
We measure the distance from your fuse box to the hot tub location, check your existing board capacity, and recommend the correct cable size.
Circuit Design
We design a dedicated 32A circuit with RCBO protection, calculate voltage drop, and submit building control notification before starting work.
Installation & Testing
We trench and bury SWA cable, install the rotary isolator, connect to your board, and test earth continuity, insulation resistance, and RCD trip times.
Compliance Certificate
You receive a BS 7671 Electrical Installation Certificate and Building Control sign-off. Keep this for insurance and property sales.

Hot Tub Wiring FAQs
? Can I plug my hot tub into a normal socket?
Only if it's a 13A inflatable model like a Lay-Z-Spa. Even then, the socket MUST be RCD protected and within 2 meters. Larger hot tubs need a dedicated 32A supply.
? How far can a hot tub be from the fuse box?
Technically unlimited, but long cable runs require thicker cable to compensate for voltage drop. We use 6mm² SWA up to 20m, and 10mm² SWA beyond that.
? Do I need building control approval?
Yes. Hot tub installations are notifiable under Part P Building Regulations. We handle the notification and provide certification for building control sign-off.
? Can I run the cable through my loft?
Not recommended. Outdoor cables should be buried or run externally in conduit. If loft routing is unavoidable, we must use fire-rated SWA cable and seal all penetrations.
? What's the running cost of a hot tub?
Typically £40-£80/month in electricity depending on size, insulation quality, and usage. Modern hot tubs with good covers are surprisingly efficient.
? Do I need an outdoor consumer unit?
Not for simple installations. A rotary isolator is sufficient. However, if you want multiple outdoor circuits (hot tub + lights + sockets), a dedicated mini-CU is recommended.
? Can you wire a hot tub on a rental property?
Yes, but you must notify your landlord and provide them with electrical certificates. Landlords also need PAT testing for plug-in hot tubs under rental regulations.
? What size breaker does a hot tub need?
13A hot tubs: 16A Type B MCB. 32A hot tubs: 40A Type B RCBO (with 30mA RCD protection built in). We'll spec the correct protection based on your hot tub model.
? Can I DIY my hot tub wiring?
Legally, no. Hot tubs are special locations under BS 7671 and require Part P notification. DIY installations void your insurance and are extremely dangerous.
? How deep does the cable need to be buried?
450mm minimum under soft ground like lawn. 600mm under driveways or areas subject to mechanical stress. We always lay warning tape 150mm above the cable.
? What if my fuse box is full?
We can install a small dedicated consumer unit just for the hot tub, fed from your main board via a 40A breaker. This also future-proofs for other outdoor electrics.
? Do you install hot tubs in Montrose?
Yes. We cover all of Angus including Montrose, Arbroath, Forfar, Kirriemuir, and surrounding areas. Average arrival time is next day for DD10 postcodes.
? Can I put a hot tub under a pergola?
Yes, but the pergola structure must not interfere with the 3.5m exclusion zone for overhead electrical equipment. We'll advise on safe positioning during the site survey.
