- A study or office that overheats during the day
- An office, shop or restaurant that is uncomfortable for staff and customers
- A system on old refrigerant that is due for replacement
What happens on the day
You do not need to do much 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. At the end, we tidy up and run through the work with you. Rural lanes and tight entrances are worth mentioning before a visit to Navestock Heath.
- We start by looking at the rooms, the walls and where the outdoor unit can go.
- Each room is sized and you get a fixed-price quote setting out the equipment and the unit positions.
- On the day, we fit the indoor and outdoor units and run the pipework, cable and condensate drain.
- Power is wired in, the joints are proved leak-tight under pressure and a vacuum pump draws out air and moisture.
- Last comes the run-up: every mode checked, the controls explained and the paperwork left with you.
Preparing for the visit
- Mention any managing agent or landlord rules we need to follow
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Tell us about access, such as roof hatches, high walls or locked plant areas

Quoting starts with a diagnosis, 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.

About our air conditioning in Navestock Heath
A new system normally needs a dedicated circuit from the fuse board. Under Part P, a new circuit is notifiable unless a registered competent person does it, and as NICEIC approved contractors we can install and certify it as part of the job. Whether you call it air con, air conditioning or an air-to-air heat pump, it’s the job we do every week across Essex.
Homes around Navestock Heath typically have room outside for an outdoor unit. The questions are more often the age of the walls, the electrics and how far the pipes need to run.
Think of the paperwork as the system’s health record: a dated account of the work and the readings we took. If anything goes wrong later, it helps the next engineer and the manufacturer and it’s worth keeping safe.

What happens if it’s left?
Refrigerant rules have changed what new systems use. Since 2025, new single split systems with less than 3 kg of refrigerant cannot use F gases with a GWP above 750, so new splits use refrigerants such as R32, with a GWP of 675. Older R410A systems have a GWP of 2088. Planning ahead for a job in Navestock Heath means we can bring everything needed.
The price reflects the work, not guesswork. That’s why every job is looked at first, and why the quote is fixed before we start.

Signs you need air conditioning in Navestock Heath
Rooms in the roof are often the hardest to keep cool. Heat comes in through the roof and rises from the rest of the building, which is why a loft bedroom can still be warm at bedtime.
Any of these is worth a proper look:
- A loft room or top floor that bakes in summer
- An ageing air conditioning system near the end of its life
- Rooms that get too hot to sleep or work in
Hill Hall (roughly 3.2 miles north-west) shows the area has its share of heritage. A listed home needs consent before an outdoor unit or pipework goes on.

Navestock Heath: your questions answered
Do I need planning permission for air conditioning in Navestock Heath?
It depends on the property. Around 8 listed entries sit within 0.5 miles of central Navestock Heath. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and isn’t used only for cooling. Listed buildings still need consent, and in a conservation area a road-facing wall or roof is not allowed under those rules. If there’s any doubt, we ask Brentwood council, which is normally the planning authority for Navestock Heath.
Can you do air conditioning in Navestock Heath?
Yes. Navestock Heath is one of the places we cover. Tell us a little about the job and we’ll take it from there.
Do you survey before quoting?
Yes, every time. Diagnosis comes before treatment: the survey shows what’s needed, where things go and what access we need and the fixed price is built on it.
Should I choose wall-mounted, ducted or cassette?
Number of rooms, space outside and how much of the unit you want to see all decide it. Ducted systems need a ceiling void or loft, and cassettes need a suspended ceiling, which we check on the survey.
What warranty do I get?
The manufacturer’s warranty, on the manufacturer’s terms. Each brand sets its own conditions and periods, so we explain them on your quote.
Does servicing affect my warranty?
That depends on the brand. If servicing is in the terms, missing one could affect a claim, so we explain the terms on your quote.
Will you work on another installer’s system?
Yes. We look at it first and tell you what we find, including anything about the original installation that needs putting right. You get a fixed price before any work goes ahead.
Air conditioning in Navestock Heath: the local picture
Valuation Office Agency council tax records date about 62% of homes in the Navestock Heath area to the post-war years, 1945 to 1972, and the 2021 Census found about 38% of households in terraced houses. We check the wall construction on homes of that age, as it decides how the pipework goes through. Terraces have little side access, so the outdoor unit normally goes on the rear wall or a flat roof, with the pipe run kept short.
Around Church of St Thomas the Apostle, a quick check of the listing and conservation maps is part of planning any install.

When something else is needed
We’ll always give you a straight diagnosis, so here’s what this work cannot put right:
- A building fabric problem such as single glazing or no loft insulation
- An installation that needs consent nobody has given yet
- A lack of fresh air (most split systems recirculate room air rather than bringing fresh air in, which is a job for ventilation)
