Connecting Garden Annexes to the Services

Your four service connections are commenced prior to installation during the Site Pack and then connected once your annexe has been installed.

The services are refered to as the two “Dry” services and the two “Wet” services

The two “Dry” Services:

Electrics We position a heavy duty 60amp SWA (protected) cable between the annexe and your house into the service trench, ready for connection at each end at the household consumer unit (fuse board) and annexe’s consumer unit. Once the annexe has been installed we then connect at both ends and issue the Part P certificate.

Cat 6 Cable: This cable is better known as internet cable and ensures the annexe is connected to the house without being reliant on wifi. Cat 6 futureproofs the annexe and enables a phone and broadband to be extended to your new home. We terminate with an RJ45 (computer socket) adjacent to your household broadband router and in your chosen location in the annexe

The two “Wet” Services

Freshwater: the freshwater pipe is connected from the house (normally close to the kitchen tap) via a stopcock and along the length of the service trench to the annexe where it reappears adjacent to the kitchen of the annexe. It’s frostproof MDPE (polypipe) and is also lagged adjacent to the house and the annexe. We hide/disguise the short length of visible pipework in location.

Drains: the annexe enjoys household sanitaryware in the kitchen and bathroom and the waste is fed out of the annexe in a normal household drain. Often we place a full gravity drain into the service trench and feedback to the household manhole (normally adjacent to the back or side of every house). When the gravitational fall for the drain is insufficient, we use a small pressurised system (buried into the ground) that automatically pumps the waste to the manhole.
