About our air source heat pumps in Hertingfordbury
Until 31 March 2027, a heat pump installed in residential accommodation carries 0% VAT, with 5% from 1 April 2027. That follows HMRC Notice 708/6, and it does not apply to businesses, and for air-to-air systems we confirm the VAT on your quote. This is general information, not tax advice. If you’re dealing with wanting to stop using oil, LPG or gas for heating and working out whether radiators need upsizing, we can help.
Space for an outdoor unit is rarely an issue near Hertingfordbury, so the design comes down to heat loss, radiators and hot water.
If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We will explain how the manufacturer’s terms are likely to apply before anything chargeable is done.

What affects the cost of air source heat pumps
Our prices page gives typical ranges, but every job is priced on its own. What we look at:
- What we find on the survey or diagnosis
- What kind of system it is
- The size of the job
No two properties are the same, so each one gets its own fixed-price quote. The system, the access, the pipe routes and the parts involved all make a difference.
Helping us quote
You don’t need the technical terms. Just send:
- Photos showing the indoor unit and the space around it
- The rating plate or label on any existing unit
- The paperwork from the last service, if you have it
Published ranges are a starting point; the quote is built on your property, because no two buildings, rooms or systems are the same. Once we’ve looked at the job, from pictures or on a survey, you get a fixed price. To start, ring 07833 053749.
Common problems we fix in Hertingfordbury
Extensions, renovations and loft conversions are a natural time to rethink the heating. Pipework, radiators and space for a cylinder are easier to plan while work is going on.
These are the situations we see most often:
- An oil, LPG or gas boiler near the end of its life
- No space for a hot water cylinder
- Wanting to stop using oil, LPG or gas for heating
For a home near Hertford North station, the survey looks at whether an air-to-water or air-to-air heat pump suits better.
What to look for in a quote
- Whether the quote shows VAT clearly
- Whether anyone has checked the property or the system first
- Exactly what the price includes, from supply and fitting to commissioning
Air source heat pumps in Hertingfordbury: the local picture
VOA council tax data date about 47% of homes across Hertingfordbury and its surrounding area to the post-war years, 1945 to 1972. Whether the walls and loft have been insulated makes a real difference to the heat pump size for homes of that period.
If your home is listed, like Digswell House about 4.6 miles north-west, listed building consent comes before any heat pump work.

How the visit works
There’s very little for you to do on the day. Someone needs to let us in and show us the units, or where they’re going, and the rest is down to us. Before we leave, the area is tidied and we explain what we’ve done. Photos of the existing unit help with repairs and servicing in Hertingfordbury.
- First we find out about the property, the heating you have now and what you are hoping for.
- On the visit we calculate what every room loses on a cold day, then check the radiators, room for a cylinder and outdoor unit options.
- We send a fixed-price quote that shows the equipment, the grant position and the VAT.
- Installation covers the outdoor unit, the indoor connections and the controls.
- Commissioning, MCS certification and a handover of the controls finish the job.
Preparing for the visit
- Move furniture away from the wall where we’ll be working
- Have the make and model of any existing unit to hand
- Tell us about parking and loading
Getting 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.
Advice
Let and managed properties
Keeping records across a portfolio is half the battle. Each visit produces a dated record, with F-Gas records wherever refrigerant work is involved, ready for a tenant, a buyer or an inspection.
Larger air conditioning systems in buildings need more than servicing: a TM44 inspection by an accredited energy assessor is required at least every 5 years for systems over 12 kW. We can arrange it, prepare the system for it and fix what it finds.
Hertingfordbury: your questions answered
Will a heat pump in Hertingfordbury need planning permission?
That depends on the building and where the outdoor unit goes. Central Hertingfordbury sits inside the Hertingfordbury Conservation Area. Heat pumps on houses are often permitted development, but listed buildings need consent and conservation areas restrict outdoor units facing a road. Where it’s needed, we check with the planning department at East Hertfordshire council, usually the authority for Hertingfordbury.
Is Hertingfordbury within the area you cover?
Yes, and the size of the place makes no difference to how we work. A few photos and the postcode are enough to get things started.
Do you protect the property while you work?
We start with protection: sheets over the floor and nearby furniture. Any drilling is agreed with you first, and we clear up the dust and offcuts before we leave.
Do I get paperwork after the visit?
Yes. You get a written record of every visit, and any work on the refrigerant circuit goes in the F-Gas records. File them with the system’s paperwork.
Am I eligible for a heat pump grant?
We check the scheme rules for your property before you go ahead. As the installer, we make the application where you qualify.
Why use an F-Gas certified company?
Anyone installing, repairing or servicing the refrigerant side must be qualified, and their company certified. Ask to see proof before booking anyone and we’ll gladly show you ours.
Do you work for landlords and businesses?
Yes. From a single let flat to offices, shops and public buildings, we work the same way: survey or diagnosis, a fixed price and proper paperwork.
