How to prepare for a heat pump installation
Before a heat pump can get installed there are two main steps that you should consider. Applying to receive the necessary permissions and enhance your home's insulation and draught-proofing to reduce energy bills and make your heat pump more efficient.
Before installing a heat pump you need to ensure compliance with local planning regulations and obtain District Network Operator (DNO) approval.
To lower energy bills, install insulation or draught-proofing to minimise heat loss. Simple insulation methods can effectively reduce your heating costs.
Step 1: Permissions
Before getting an air source heat pump, we suggest learning about the following topics:
Planning Permission
Planning permission isn't usually required for water source heat pumps on residential properties, as they're typically permitted developments.
However, you should consider the following factors:
-
Location: Properties in designated areas like national parks or World Heritage Sites may have additional restrictions. Regional differences in the UK can also affect regulations.
-
System Specifications: The size, design, and placement of the heat pump may require permission, particularly if it impacts the landscape.
-
Noise and Visual Impact: The pump must not be noisy or visually intrusive.
Consult local authorities or experts to ensure compliance and determine if planning permission is necessary.
District Network Operator permission
Before installing a heat pump, you must obtain permission from the District Network Operator (DNO) to ensure the local network can handle the additional load. Installing without permission may result in being required to remove the heat pump. When selecting a heat pump installer, consider their ability to navigate the DNO process. Securing DNO approval is also a requirement under the MCS scheme.
Step 2: Insulation improvements
Improving insulation in your home is a key way to reduce heat loss and lower energy bills.
Here are some effective types of insulation you can consider:
Roof and loft insulation:
A significant amount of heat is lost through the roof of an uninsulated home. Insulating your loft, attic, or flat roof can effectively reduce heat loss and lower heating costs. Properly installed loft insulation can pay for itself many times over during its 40-year lifespan.
Wall insulation:
Cavity wall insulation is another effective way to reduce energy loss and cut heating bills. While homes built after the 1990s typically have wall insulation, older houses may not. Cavity walls can often be insulated by injecting insulation material into the walls through drilled holes, which are then sealed with cement.
Double glazing:
Energy-efficient windows, available in various frame materials and styles, are designed to minimise heat loss, maximise sunlight, and prevent air leaks. Double-glazed windows have two glass panes with a 16mm gap, while triple-glazed windows have three panes and two gaps, offering potentially better insulation. The gaps are filled with air or an inert gas like argon, and are completely sealed.
Draught proofing:
Draught-proofing is an affordable and effective method to save energy and money. By blocking unwanted gaps that let cold air in and warm air out, you can reduce the need for heating, save money, and keep your home cosy while still allowing for controlled ventilation to manage condensation.
