Garden rooms are increasingly being used as home offices, workshops, bars, gyms and places to relax. Once lighting, sockets, heating or a hot tub are added, an extension lead from the house is no longer a sensible long-term solution.
We recently completed a dedicated electrical installation for a garden room and hot tub at a property in Amington, Tamworth. The customer needed a permanent supply that could safely power the garden building’s lighting and sockets while also providing a separate supply for the hot tub.
Planning the new garden electrical supply
Before installing any new outdoor supply, the cable route and the electrical demand need to be considered carefully.
For this project, the supply cable had to travel from the house, around the outside of the property and along the garden boundary before reaching the garden room. The route was planned to keep the cable secure, neatly positioned and protected against accidental damage.
The installation also needed to provide separate protection for:
- the garden room lighting
- the internal sockets
- the hot tub
- additional outdoor sockets
Keeping these parts of the installation on separate circuits means that a problem with one area is less likely to leave the entire garden building without power.
A new consumer unit in the garden room
A new metal consumer unit was installed inside the garden room to distribute and protect the new circuits.
The consumer unit included individual circuits for the internal lighting, general-purpose sockets and the hot tub supply. Surge protection was also fitted, together with clear circuit identification.
Surge protection helps reduce the risk of damage to connected electrical equipment caused by short-duration voltage surges
That can be particularly useful in a garden building containing televisions, computers, chargers, audio equipment or hot-tub controls.
Internal lighting and sockets
The garden room was fitted with its own internal lighting and a conveniently positioned light switch. General-purpose sockets were also supplied from the new consumer unit, allowing the building to be used without cables trailing back towards the house.
A properly designed permanent supply is usually a much better arrangement than relying on extension leads, especially where the room will be used regularly or throughout the year.
It also allows the position and number of sockets to be planned around how the garden room will actually be used.
Dedicated power and isolation for the hot tub
The hot tub was supplied from its own protected circuit rather than sharing the general socket circuit.
A local rotary isolator was installed close to the hot tub, together with a weatherproof connection point. This provides a clearly identifiable means of switching off the hot-tub supply locally when required.
Hot tubs can place a substantial and sustained load on an electrical installation. The manufacturer’s electrical requirements, cable length, protective devices, earthing arrangement and existing supply capacity all need to be checked before the circuit is installed.
Simply plugging a hot tub into whichever outdoor socket happens to be nearby may not provide a suitable permanent arrangement.
Additional outdoor sockets
Weatherproof sockets were installed outside the garden room to provide practical power around the garden.
These can be useful for equipment such as:
- lawnmowers and garden tools
- outdoor lighting
- pressure washers
- entertainment equipment
- occasional maintenance work
Their position should be planned carefully so they are convenient to use without encouraging long extension leads to be run across paths or lawns.
Neat external cable routing
A large part of this installation involved finding a practical route from the house to the garden room.
The cable was clipped neatly around the exterior of the house, taken through a weatherproof transition point and then continued along the garden boundary before entering the garden building.
The photographs show the cable following the brickwork and boundary rather than cutting awkwardly across the garden. This keeps the installation comparatively unobtrusive while still allowing the route to be inspected and maintained.
Outdoor cables and accessories must also be suitable for their surroundings and protected against weather, physical damage and deterioration.
The supply route was planned around the property and along the garden boundary.
Inspection, testing and certification
Once the installation was completed, the new circuits were inspected and tested.
This included checking the protective devices, earthing arrangements and final connections before the installation was certified and handed over to the customer.
Testing is not merely the final flourish on the paperwork. It confirms that the protective measures operate correctly and that the completed installation is suitable to be placed into service.
Are you adding power to a garden room or hot tub?
The best time to plan the electrical installation is before the inside of the garden building is fully decorated or the hot tub is delivered. It gives more freedom to choose cable routes, socket positions, lighting points and the location of the consumer unit.
