The process
Everything the job needs comes with us, from tools and test equipment to ladders and dust sheets. All we ask is clear access to the units, or to where they’ll go, and to the consumer unit. On site, the work takes from a couple of days for a few cassettes to a planned programme for a whole building. Everything the job in Writtle needs is worked out beforehand.
- We survey the site and talk through how each area is used.
- You get our recommendation and a fixed price.
- The programme is agreed, including any out-of-hours or phased work.
- The system is installed, wired and connected to its controls.
- We commission the system and hand over the F-gas records and controls.
How to prepare
- Find the manual or the paperwork for the system, if you have it
- Make sure we can reach the outdoor unit, or where it will go
- Make sure we can reach the consumer unit or fuse board
How to get a quote
Published ranges are a starting point; the quote is built on your property, because no two buildings, rooms or systems are the same. After a look at the job, by photos or a survey, the price is fixed. To get going, ring 07833 053749, or email if that’s easier.
Advice
Commercial air conditioning in Writtle, done properly
Every commercial job is commercial systems priced after survey. We look at the building, the people in it, the equipment and the hours it’s used, then send a fixed-price quote. So you know exactly what you are getting and what it costs. The work covers VRF systems, ceiling cassettes and wall-mounted split systems, and people most often call us about ageing air conditioning that keeps breaking down and offices that get too hot in summer.
Around Writtle, commercial jobs are usually a shop, surgery, pub, office or workshop. Many need just one to four indoor units, sized from a site survey.
Equipment warranty comes from the manufacturer, on its own terms, and we explain those terms on your quote. Terms differ from brand to brand, and we’re happy to talk you through them.

Other services in Writtle
How the job changes from property to property
VRF and VRV systems
Some VRF systems can heat some rooms while cooling others on systems designed for it. We explain whether that would help your building.
Shops and restaurants
Where appearance matters, ducted or cassette units keep equipment out of sight.
Owner checks or an engineer?
On air conditioning, the filters in the indoor unit are typically the one part owners can clean where the manufacturer’s manual explains how. With the power off, they lift out, can be vacuumed or rinsed and must be fully dry before they go back. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.
Owner care supports servicing; it does not replace it. Simple care keeps the air moving through the system, but the inside of the units, the refrigerant and the electrics still need a qualified engineer.
Fixed-price quotes for commercial air conditioning in Writtle
You will get a fixed price before any work starts. It takes into account:
- What kind of system it is
- A single visit or a regular plan
- How many units are involved
Leaving a fault or an overdue service rarely makes the work cheaper. Faults and wear in a system tend to grow, and a struggling system uses more electricity to do less. If you are unsure, phone us on 07833 053749 or use the quote form for straight advice and a fixed price.
What to send for a quote
Before you ask for a quote, gather:
- A close-up of the unit’s label showing the model number
- The remote or wall controller showing any error
- The outdoor side of the property, including any roof or flat area
Photos are enough for some jobs; others need a visit first. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, the quote is fixed before anything goes ahead.
Questions from Writtle
Can you do commercial air conditioning in Writtle?
Yes. We work across London and the South East from our base in East Grinstead, and Writtle is part of that. Tell us a little about the job and we will take it from there.
Is planning permission needed for air conditioning in Writtle?
There’s no single answer: the building and the outdoor unit position decide it. Central Writtle is a short walk from the Writtle Conservation Area. A system that heats as well as cools may not need an application on a house, provided it stays within the permitted development limits. Cooling-only units get no such allowance, and listed buildings and road-facing positions in conservation areas need more care. We speak to the planning department at Chelmsford council, typically the authority for Writtle when it matters.
Who is responsible for leak checks?
Responsibility is shared between the operator, usually 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.
Can you install out of hours?
Yes, timing is agreed to suit you. Every type of building has its own pattern and the plan reflects it.
Do you carry out TM44 inspections?
No, the inspection needs an accredited energy assessor. We can prepare for the inspection and put right what it finds.
Do you provide ongoing maintenance for businesses?
We do, with contracts covering servicing, leak checks and the paperwork. The visits and price are fixed with your quote.
What accreditations do you have?
F-Gas certified, NICEIC approved and MCS certified for heat pumps, and we’re Checkatrade members. Our engineers also hold the individual F-gas qualifications needed to work on refrigerant.
What commercial work looks like in Writtle
Food Standards Agency records list about 25 cafés, restaurants and staff canteens, about 7 schools and colleges and about 5 care homes, nurseries and hospitals within about 1.5 miles of central Writtle. Kitchens and dining rooms gain heat quickly, and hotels need quiet units in guest rooms, so each is designed for its use.
Before any plant goes outside a building like Church of All Saints, its trustees may need planning or heritage advice, and we work with whoever gives it. For a school like Writtle Infant School, air conditioning work is best done out of term.
