Air source heat pumps in Hudnall Corner
We install air source heat pumps in Hudnall Corner and across Hertfordshire, and we are MCS certified. There are two kinds: air-to-water, which heats radiators or underfloor heating and your hot water, and air-to-air, which warms rooms through indoor units and can also cool. We will explain which type fits your home and why. Common call-outs are for checking eligibility for a heat pump grant and replacing a combi boiler with a heat pump, on hot water cylinders, underfloor heating and air-to-water heat pumps.
Homes around Hudnall Corner usually have room outside for a heat pump, so the design focuses on heat loss and radiators.
Whatever the visit, you get a written record: commissioning details for an installation, a fault and repair note for a repair, or a record of the service. Keep it with the system’s paperwork so it’s to hand next time.

Hudnall Corner: your questions answered
Can I get the Boiler Upgrade Scheme grant in Hudnall Corner?
Yes, the scheme covers homes in England, including Hudnall Corner, if they qualify. The grant is £7,500 for an air source (air-to-water) heat pump and £2,500 for an air-to-air system that replaces the existing fossil-fuel heating. We hold MCS certification, so the application is ours to make for you.
Do you cover smaller places like Hudnall Corner?
We do. Villages and hamlets get the same service as the bigger towns. Visits to smaller places are planned so the engineer arrives with what the job needs.
What’s the difference between air-to-water and air-to-air heat pumps?
Air-to-water feeds your central heating and hot water, while air-to-air warms and cools rooms directly. With air-to-air, hot water needs another source and the survey helps decide.
Can you come out in an emergency?
Yes, day and night. Call the emergency line and tell us the make, the symptoms and any error code, and we’ll advise on what to do next.
Can we book visits on a schedule?
Yes. Tell us what you have and how it’s used and we will propose a schedule and quote for it. Leak checks required by the F-gas rules can be built in for larger systems.
Is there a survey before the work?
Yes. Photos often do the job for simple work, while bigger systems and repairs that need testing get a visit.
What’s the price of a heat pump installation?
An air-to-water heat pump costs £8,000–£16,000 (0% VAT on homes) before the grant. Eligible homes in England and Wales can get £7,500 through the Boiler Upgrade Scheme, and we confirm eligibility before you commit.
The process
We book the visit for a day and time that suit you, and we let you know if plans need to move. On arrival, the engineer compares the job with the survey, your pictures or the details you gave us. Anything unexpected is raised with you before we go further. From there, the work takes from a couple of days to around a week, depending on the system and how much of the heating changes. Photos of the room and the outside of the property help us plan a visit to Hudnall Corner.
- We talk through your home, your current heating and what you want from a heat pump.
- A heat loss survey works out how much heat each room needs, and we look at the radiators, the cylinder space and where the outdoor unit could go.
- You get a fixed-price quote, with any grant you’re eligible for and the VAT explained.
- The outdoor unit, the indoor equipment and the controls are installed and connected.
- Once it’s running correctly, the MCS certificate is issued and we show you the settings.
Preparing for the visit
- Tell us about any building rules, permits or sign-in
- Make sure someone can let us in at the agreed time
- Clear the space around the indoor unit, or where it will go
Ask for a quote
The quickest way to a quote is to send pictures: the inside and outside of the property where the work is, plus the rating plate of any unit already there. Add the address and what you’d like done, and many jobs can be priced from that.

What happens if it’s left?
The 0% VAT rate on heat pumps in homes runs until 31 March 2027, then 5% applies. If you are thinking about a heat pump, that date is worth knowing alongside your own plans for the property. A system that’s left with a fault, or without a service, normally costs more to run.
Leaving a fault or an overdue service rarely makes the work cheaper. Faults and wear in a system tend to grow, and a system working harder than it should costs more to run. If you are not sure what’s needed, phone us on 07833 053749 or drop us a line and we’ll give you an honest view and a fixed price.
