Where do the services for my new extension come from?


Services which will need to be considered when building a home extension.

Services consist of your gas, water, electricity, and waste pipes. It is important to consider these during the design stage. A good architect and structural engineer should be able to advise you on a suitable layout and what additional provisions will need to be implemented in the design.


For new sinks, showers, toilets, and kitchen appliances. These will be taken from your existing supply and extended into the areas such as a new kitchen, bathroom, or utility room.


A gas hob in a kitchen is usually relocated if the proposed extension is to create additional space for new kitchen and remodel. For more information on gas boilers continue reading.


Are usually extended from the existing supply but it is always best to check the limitations of your existing boiler. Hot water for a kitchen or bathrooms places additional demands on your boiler too. As part of our service, we can work out how many additional radiators you require, what size they need to be and work out if your existing boiler and header tank is sufficient.


Like additional water supplies for sinks, toilets, and appliances. Your existing consumer unit will need to be checked to ensure there is additional space on your existing board to accommodate new services such as lighting and plug sockets etc.

Again, we can advise if your existing board is sufficient to take the additional loads placed upon it from your new circuits.


Additional drainage is usually connected into your existing drainage system. Depending on what type of system your home currently has will determine what connections that will be permitted.

Drainage systems are broken into three main categories which are Surface Water Drainage, Foul Water Drainage or Combined System Drainage.

Surface Water Drainage – takes rainwater away from your home in a separate drainage system to the Foul Water.

Foul Water Drainage – takes waste away from your home in a separate drainage system to Surface Water.

Combined System Drainage – takes both foul and rainwater away from your home in a combined drainage system. This usually applies to older buildings that were built prior to modern day building regulation requirements.

Network Services

Considerations also need to be given to whether the ground you are proposing to build your extension has existing services running beneath it owned by a network. As part of our service, we can advise you what steps to take to prevent liabilities for building over a network service provider’s facility.
