If you’re asking “do I need planning permission for a heat pump?”, the short answer is that most homes don’t. Eco Air Source Heat Pump Installer is a Walsall-based business, and this is one of the first questions homeowners put to us. Below, we explain when permission isn’t needed, when it’s worth checking, and what to do before you book an installation.
Is planning permission needed for most homes?
Usually not. Most heat pump installations are permitted development, so no planning permission is needed. The exception is if you live in a listed building or conservation area, where you should check with your local planning department first (Energy Saving Trust, 2026).
“Permitted development” means certain building work is allowed by national rules without a separate planning application. For many ordinary houses in Walsall, Willenhall, Bloxwich, Aldridge and Brownhills, an outdoor heat pump unit falls under those rules. The detail of the conditions is set out on the Planning Portal and GOV.UK, and you should read those for the official position. We can’t give legal advice, but we can tell you what we look at during a survey.
When should you check with the council?
Check first if your home is listed or in a conservation area. Those are the two cases the Energy Saving Trust (2026) flags. A quick call to Walsall Council’s planning team will tell you where you stand before you spend anything.
A few other situations are also worth a phone call:
- Flats and maisonettes: the outdoor unit may sit on shared or leased land, so you’d need the freeholder’s agreement as well.
- Rented homes: landlords should check the lease and any management company rules.
- Tight plots: if the unit has to go close to a boundary or the front of the house, ask the council to confirm.
Permitted development rules and planning permission are separate from any rules in your deeds or lease, so it’s worth checking both.
Where does the outdoor unit go?
Placement is decided on the survey. Even where no planning permission is required, the unit still needs clear airflow, a firm base and sensible access for servicing. We look at this at your free home survey, and you get a written quote afterwards.
Neighbours matter too. Putting the unit away from a bedroom window, whether yours or next door’s, is good practice and avoids disputes later. A monobloc heat pump keeps all its components in one outdoor unit and is cheaper and quicker to install, while split systems can be slightly more efficient (Energy Saving Trust, 2026). Which one suits your home may affect where the equipment goes. Inside, you’ll typically need space for a hot water cylinder, which can usually fit in any cupboard measuring at least 80cm x 80cm (Energy Saving Trust, 2026).

How does planning fit with the grant and the cost?
Planning is separate from funding. Homes in England and Wales can get £7,500 towards an air source heat pump through the Boiler Upgrade Scheme (Energy Saving Trust, 2026). You must own the property and be replacing a fossil fuel system such as oil, gas, electric or LPG (GOV.UK, 2026).
We are not MCS certified. If you want the grant, it comes through our MCS-certified partner, who quotes, installs and applies on your behalf. GOV.UK says the grant value is taken off the installation price and shown on your quotation and invoice (GOV.UK, 2026). If you don’t need the grant, we install the heat pump ourselves.
On cost, guides vary. The Energy Saving Trust puts a typical installation at around £12,000 (2026), while Worcester Bosch quotes £5,000 to £15,000 (seen Oct 2026). Your own figure depends on your home, so we put it in writing.

Frequently Asked Questions
You should check with your local planning department before going ahead. Most installations don't need permission, but the Energy Saving Trust (2026) specifically says to check if you live in a listed building or conservation area. A short call to the council gives you a clear answer.
Planning rules are the same, but you'd also need your landlord's consent, as the unit is fixed to the property. Landlords should check their lease and any management company rules. For the official position, check GOV.UK or the Planning Portal.
We look at placement and likely planning issues at your free survey and flag anything to confirm with the council. The final responsibility for checking sits with the property owner, so for listed or conservation area homes, please contact the planning department yourself. Call [01922 302461](tel:+441922302461) or request a free survey, and we'll talk through your home and your options.
