Air source heat pumps in Walkern
In England, an air source heat pump on a house can often go in under permitted development rights. The conditions include an outdoor unit of no more than 1.5 m³ and compliance with MCS 020(a), and the unit cannot be used solely for cooling or sit within the curtilage of a listed building. We check the rules for your property as part of the survey. If the problem is choosing between air-to-water and air-to-air and planning and permitted development questions, we can help.
In a place like Walkern, some homes are listed, and permitted development doesn’t cover listed buildings, so consent comes first.
Equipment warranty comes from the manufacturer, on its own terms, and we explain those terms on your quote. Terms differ from brand to brand, so we go through them with you rather than leave you to find the small print.

What we’re called out for in Walkern
Some homes heated by electric heaters or storage heaters consider a heat pump instead. The survey tells you whether it’s practical and what’s involved, and we explain the grant position for your home.
Customers typically contact us when they notice one of these:
- Not knowing whether a grant applies
- Comparing heat pump types
- Wanting to stop using oil, LPG or gas for heating
Period properties close to Parish Church of St Mary the Virgin can suit a heat pump, though insulation and any heritage protection are checked first.

Walkern questions
Will you come out to Walkern?
Yes. Walkern is within the area we cover across London and the South East. Visits to smaller places are planned so the engineer arrives with what the job needs.
Does the Boiler Upgrade Scheme cover homes in Walkern?
Walkern is in England, where the Boiler Upgrade Scheme runs. The amount depends on the type of heat pump, and the survey confirms which applies. We hold MCS certification, so the application is ours to make for you.
Can I do any of the installation myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That’s the law, not just our preference, and manufacturers expect it for their warranty too. We are happy to quote for the full job, supply to commissioning.
What does an air-to-water heat pump cost?
For air-to-water, the price is £8,000–£16,000 (0% VAT on homes) before any grant. Eligible homes in England and Wales can get £7,500 through the Boiler Upgrade Scheme, and we confirm eligibility before you commit.
How long will it take to install a heat pump?
Expect it to take a few days on site, depending on the cylinder, the radiators and the pipework involved. How much of the heating changes decides most of the time, and we confirm the timing with your quote.
Can landlords and managing agents book you?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size in Walkern and across Hertfordshire. Tell us who should receive the paperwork.
Do you protect the property while you work?
We put dust sheets over floors and furniture near the work first, and we tidy up as we go. Before we leave, we clear up and run through the work with you.
What a heat pump looks like in Walkern
About 65% of households live in detached or semi-detached houses, according to Census 2021 figures. Houses usually have space for an outdoor unit and a hot water cylinder. The centre of Walkern lies within the Walkern Conservation Area. About 37 listed entries lie within half a mile of central Walkern, Farmhouse at Manor Farm (grade II*) among them. So the heat pump survey asks two extra questions here: is the home listed, and is it inside a conservation area?
Aston Bury, roughly 2.9 miles south, is a reminder to check your home’s listing status: permitted development doesn’t cover listed buildings.

Pricing air source heat pumps in Walkern
Typical ranges are on our prices page, and your quote is built on your job. What we look at:
- The equipment or parts the job needs
- How many units are involved
- What kind of system it is
What you pay reflects the actual work. That is why we look at the job first, from pictures or on a survey, and the price is agreed before we start.
Before you get in touch
There’s no need for technical detail. Just send:
- The rating plate or label on any existing unit
- The postcode and whether it’s a home, flat or business
- Wide photos of the room or the existing unit
Our prices page gives typical ranges, but your quote is based on your job, because every property is different. Once we’ve looked at the job, from photos or on a survey, you get a fixed price. To start, phone us on 07833 053749.
What air source heat pumps can’t fix
Air source heat pumps cannot fix everything, and we’d rather say so up front. It doesn’t solve:
- Promising eligibility for the Boiler Upgrade Scheme
- Getting planning permission or listed building consent on your behalf
- Tax advice on your own circumstances
If in doubt, phone us on 07833 053749 or use the quote form and we will say what we think before you book.

How it works
Protection comes first: sheets over the floor and any furniture nearby and nothing is moved without asking you. After that, anything electrical is made safe and we start. It takes several days for an air-to-water system with a new cylinder, less for an air-to-air system, and we clear up before we go. Pictures of the space and where the outdoor unit could go let us plan the work in Walkern.
- You tell us about the home and what you want from a heat pump.
- We survey for heat loss and look at radiators, cylinder space and outdoor unit options.
