What Is a Heat Pump?

A heat pump is an energy-efficient system that transfers heat from outside sources—air, ground, or water—into your home for heating or hot water. There are two main types:

• Air Source Heat Pumps (ASHPs) – Extract heat from the air.

• Ground Source Heat Pumps (GSHPs) – Extract heat from the ground.

Heat pumps work using electricity but are much more efficient than traditional heating systems, producing more energy than they consume.

Why People Choose Heat Pumps in London

Londoners are increasingly choosing heat pumps for several reasons:

• Eco-Friendly Heating: Heat pumps drastically reduce carbon emissions compared to gas boilers.

• Lower Energy Bills: While upfront costs are higher, long-term savings are substantial.

• Government Incentives: Schemes like the Boiler Upgrade Scheme (BUS) offer grants for heat pump installations.

• Future-Proofing Homes: With the UK government planning to ban new gas boiler installations in future, heat pumps are a sustainable alternative.

General Planning Permission Rules in England

In England, including London, many small-scale home improvement projects fall under Permitted Development Rights. These rights allow certain changes without the need to apply for formal planning permission.

Heat pump installations may fall under these rights Electric Storage Heating in london  provided certain criteria are met. However, there are key exceptions, especially in protected areas.

When You Don't Need Planning Permission

For Air Source Heat Pumps, planning permission is usually not required if:

1. The volume of the unit (including housing) is below 0.6 cubic metres.

2. The unit is more than one metre from the boundary of the property.

3. It’s not installed on a pitched roof.

4. It’s not on a wall that faces a highway (if on a building).

5. There is no more than one ASHP unit on the property.

These conditions are part of the Permitted Development Rights for renewable technologies in residential buildings.

For Ground Source Heat Pumps, permission is generally not needed, as most components are underground. The visible infrastructure is minimal, and in most residential settings, it falls under permitted development.

However, these rules can change depending on your local authority or if your property has special conditions.

When You Do Need Planning Permission

There are several scenarios where planning permission is required in London:

2. Conservation Areas

London has many conservation areas, like parts of Kensington, Camden, and Greenwich. If your home is in such an area, restrictions are tighter. Installing a heat pump on a visible wall or close to a boundary may require planning permission.

3. Flats and Apartments

Permitted development rights do not apply to flats or maisonettes. In such cases, you’ll need to submit a full planning application.

4. Non-Residential Buildings

For commercial properties or shared residential buildings (like HMOs), planning rules differ. You may need a change-of-use permission or other approvals.

5. Noise Concerns

Air Source Heat Pumps generate some noise. If your installation could exceed noise limits set by your borough council, you may be required to seek planning permission and demonstrate compliance.

You’ll need to prepare documents like:

• Site plan and property drawings

• Details of the proposed heat pump (make, model, size)

• Impact assessments (e.g., noise or visual impact)

Applications are submitted online through your borough’s planning portal or the national Planning Portal website.

3. Wait for Decision

Local authorities typically take 6–8 weeks to make a decision. You’ll receive a formal letter or email confirming approval or refusal.
