Air source heat pumps for homes and businesses in Felden

Installing an air source heat pump in a home is zero-rated for VAT until 31 March 2027, then 5%. That follows HMRC Notice 708/6, and it does not apply to businesses. For air-to-air systems, we confirm the VAT on your quote. Please treat this as general information rather than tax advice. If you’re dealing with plans to switch to electric heating with a heat pump and checking emitters for a heat pump, we can sort it out.

Cottages and older homes near Felden can lose heat faster, so a proper heat loss calculation matters. Sometimes insulation first is the better investment.

The records are your system’s health record: what was fitted or found, what was done and when. It makes the next visit quicker and any warranty question simpler, so keep it safe.

Advice

Air source heat pumps around Felden

About 64% of homes in the Felden area date from 1945 to 1972, according to Valuation Office Agency council tax records, and the 2021 Census found about 40% of households in terraced houses. Whether the walls and loft have been insulated makes a real difference to the heat pump size for homes of that period. In a terrace, the outdoor unit position and the MCS noise check need particular care. About 11 listed entries lie within half a mile of central Felden, Snatchup End Cottages (grade II*) among them. For a heat pump, permitted development does not apply within the grounds of a listed building, and in a conservation area the outdoor unit cannot go on a wall or roof facing a road, so we check with the local planning authority (normally Dacorum council) where needed.

With High Elms Manor about 3.4 miles south-east, it’s worth asking whether your own home is listed before planning a heat pump. Older homes near Church of St Mary may need extra checks for planning and heat loss before a heat pump is designed.

What you can do yourself, and what needs us

There are a few things you can safely do yourself: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Anything inside the units, the electrics and the refrigerant is engineer’s work.

For air conditioning, cleaning the indoor unit’s filters is the main job owners can do where the manufacturer’s manual explains how. They come out, get a gentle clean and go back only when they’re dry. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.

Questions from Felden

Can I get the Boiler Upgrade Scheme grant in Felden?

Yes, if the home and the heat pump meet the scheme’s rules: Felden is in England, where it applies. Whether your home qualifies, and for how much, depends on the type of heat pump and the heating it replaces. You don’t apply yourself: the MCS certified installer does, which is us.

Is Felden within the area you cover?

Yes, and the size of the place makes no difference to how we work. Send a few details and photos, and we reply the same working day.

Is a heat pump permitted development?

In England, many air source heat pumps on houses can be permitted development, if the conditions are met. The outdoor unit must be 1.5 m³ or less, comply with MCS 020(a), not be cooling-only and not be within a listed building’s curtilage.

Do you work on systems someone else installed?

Yes. Systems fitted by other companies are fine from all the leading brands. Tell us the make and model and send any paperwork you have.

Who has to arrange F-Gas leak checks?

Responsibility is shared between the operator, normally whoever owns or controls the equipment, and the service technicians. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.

Is the equipment covered by a warranty?

It’s the manufacturer’s, and the terms are theirs. Some brands make regular servicing a condition, so keep your service records.

Do you offer maintenance contracts?

Yes. We offer maintenance contracts, set at the interval the system and the manufacturer’s terms need. Each visit is written up and F-Gas records kept where they apply.

When something else is needed

We’d rather tell you now than sell you work that won’t help, so these are the things it will not cover:

  • Planning approval where permitted development doesn’t apply
  • Improving the building’s insulation
  • Tax rulings, which only HMRC can give

If in doubt, phone 07833 053749 or send an email and we’ll say what we think before you book.

What we work on in Felden

  • Radiator systems
  • Homes heated by oil, LPG or gas
  • Underfloor heating
  • Air-to-water heat pumps
  • Hot water cylinders
  • Air-to-air heat pumps

Looking after your system

Looking after the system is mostly common sense. Our tips:

  • Look at insulation alongside the heat pump
  • Don’t block radiators or indoor units with furniture
  • Keep to regular servicing

Where we applied for a Boiler Upgrade Scheme grant, we keep you informed through the process, as the installer applies for it.

Don’t cover radiators with furniture or heavy curtains, as the system relies on them giving out heat.
