If you’re considering making the switch to a more sustainable heat pump system, there’s now even more reason to act.
The UK government has just announced new changes to Permitted Development Rights (PDR) for air source heat pumps in England – and it’s very welcome news for homeowners, especially here in Stockport and across Greater Manchester.
The updated legislation came into effect last week, streamlining the process for installing heat pumps by reducing some of the planning restrictions that have previously made it trickier or more expensive for households to upgrade their systems.
What’s Changed?
Here’s a breakdown of the key changes to the PDR that make installing heat pumps more accessible:
- Heat pumps can now be installed within 1 metre of a property boundary.
This is particularly beneficial for homes with limited outdoor space, common in many areas around Stockport. - The allowable size of the unit has increased from 0.6m³ to 1.5m³.
That means larger, more powerful systems can now be installed without requiring additional planning permissions. - Detached houses can now install up to two air source heat pumps under permitted development.
This is ideal for larger homes or those looking to install separate systems for different parts of the property. - Air source heat pumps used for cooling now also qualify.
Previously, permitted development only applied to heating. Now, air-to-air heat pumps that provide cooling in summer months are included too – offering year-round comfort and efficiency.
Why This Matters
These changes are a big win for homeowners and the environment. They simplify the process of switching to low-carbon heating solutions, which are crucial if the UK is to meet its net zero targets.
For local homeowners in Greater Manchester, particularly in areas like Stockport where property layouts vary widely, these relaxed rules mean less hassle, reduced costs, and quicker installations.
Thinking of Installing a Heat Pump?
If you’ve been on the fence about getting a heat pump, there’s never been a better time. Not only are they more accessible thanks to these rule changes, but you may also be eligible for financial incentives like the Boiler Upgrade Scheme – designed to help cover the cost of replacing old, inefficient heating systems. Solarus are certified to install under the BUS scheme, which if you qualify, can save you £7500.
