Managing agents and facilities teams in Nup End Green

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.

Portfolio owners often want one contractor and one number. We work across London and the South East, so work at different addresses can be planned together and kept to a regular schedule.

How we handle air source heat pumps in Nup End Green

Heat pumps run at lower flow temperatures than most boilers which means some radiators may need upsizing. The survey shows which rooms are fine and which need changes and anything that needs changing is in the quote. We’re often asked to deal with questions about where the outdoor unit can go and replacing a combi boiler with a heat pump, across air-to-water heat pumps, homes heated by oil, LPG or gas and air-to-air heat pumps.

Older and listed homes in villages like Nup End Green need extra care, because permitted development does not apply within the grounds of a listed building, so consent comes first.

Equipment warranty comes from the manufacturer, on its own terms, and we set them out 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.

Common questions in Nup End Green

Can I fit a heat pump in Nup End Green without planning permission?

There’s no single answer: the building and the outdoor unit position decide it. The centre of Nup End Green is in the Old Knebworth Conservation Area. On a house, an air source heat pump can often go ahead under permitted development, with an outdoor unit of no more than 1.5 cubic metres and an installation that meets MCS 020(a), which includes a noise check. Those rights do not reach the grounds of a listed building, and conservation areas rule out walls or roofs facing a road. If that might affect you, we ask the planning department at North Hertfordshire council, usually the authority for Nup End Green.

Is the heat pump grant available in Nup End Green?

Yes, the scheme covers homes in England, including Nup End Green, if they qualify. For an air-to-water heat pump the amount is £7,500; an air-to-air system can get £2,500 if it replaces the fossil-fuel heating outright, meets the home’s full heating demand and is not an add-on to a boiler. As an MCS certified installer, we apply for it on your behalf.

Does servicing affect my warranty?

It can, for some brands. Send us the make and model and we will tell you what the manufacturer expects and stick to the interval they set.

How does the warranty work?

The manufacturer’s warranty, on the manufacturer’s terms. Each brand sets its own conditions and periods, so we explain them on your quote.

Can I do the refrigerant work myself?

No, not the refrigerant side. The F-gas rules require certified companies and qualified engineers for it, and a new electrical circuit is notifiable building work unless a registered competent person does it.

Should I choose air-to-water or air-to-air?

It depends on your home, your heating and whether you want cooling. The grant is £7,500 for eligible air-to-water systems and £2,500 for air-to-air in limited cases, and we set out the options after the survey.

Do you protect the property while you work?

We start with protection: dust sheets over floors and anything close to the work. Holes and fixings are agreed with you, and we clean up afterwards when we finish.

Do you need air source heat pumps in Nup End Green?

For homes with no mains gas, heated by oil or LPG, a heat pump is well worth considering. Until March 2027, an extra £1,500 is available for air source and ground source heat pumps in homes heated by oil or LPG with no mains gas, subject to the scheme rules.

Customers typically contact us when they notice something like this:

  • Deciding on the outdoor unit position
  • Checking whether planning permission is needed
  • Not knowing whether a grant applies

If your home is listed, like Knebworth House about 0.6 miles north-east, listed building consent comes before any heat pump work.

How to choose an air conditioning engineer

What happens on the day

Where something has to be switched off during the work, we agree it with you first, so you can plan around it. For businesses, we can normally work room by room or zone by zone. The work takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. We plan the trip to Nup End Green around you.

  1. It begins with your house and the heating it relies on now.
  2. We measure heat loss for every room.
  3. From those figures we size the heat pump and decide on radiators, cylinder and outdoor position.
  4. You get a fixed price, with any grant and the VAT set out.
  5. We install, commission and register the system under MCS.

Getting ready for the visit

  • Have the make and model of any existing unit to hand
  • Unlock any gate, garage or side passage we need
  • Make sure someone can let us in at the agreed time

How to get a quote

Every quote starts with a look at the job, from a site survey or, where the job is straightforward, from pictures and measurements. After that, we send a fixed price so you know the cost before we begin.

Advice

Owner checks or an engineer?

Leave the units and pipework where they are. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrical side needs a competent person. Ask us to quote for a move instead.

Never try to top up, release or handle refrigerant yourself. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and escaping refrigerant can cause cold burns. A suspected leak is our job, not yours.

A customer’s words

“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
