About our commercial air conditioning in Newgate Street
There’s no single best commercial system. Splits for small rooms, cassettes for open-plan ceilings, ducted for a hidden finish and VRF or VRV for many zones on one system. We explain the options and why we’d choose one over another. The work covers ducted systems, wall-mounted split systems and VRF systems, and the jobs we see most are work raised by a TM44 inspection and missing F-gas records for commercial systems.
If you run a village hall or similar building near Newgate Street, heating and cooling that warms up fast suits a space used on and off.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We will tell you how the manufacturer’s warranty is likely to apply before anything chargeable is done.

What the work involves, system by system
Offices
Offices gain heat from occupants, equipment and the sun. The system is sized for what the space really needs with units that fit the layout.
Shops and restaurants
Dining areas fill and empty over the course of service and the controls need to handle that.
Before you call an engineer
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. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.
Write down what you notice: error codes, noises, drips, smells or a drop in performance. It makes our diagnosis quicker, and a photo of the display helps even more.
How it works
On the day, we arrive at the time agreed with you and check the plan with you first. Dust sheets go down over floors and anything close to the work, and anything electrical is made safe before work starts. The work itself takes as long as the site and the system need, from a short install to a phased project planned around opening hours. For a place like Newgate Street, the timing is set with you and the travel is our side of the planning.
- We start with the details of the building and the problem.
- We survey the site to check heat gains, layout and access.
- The options, cost and timing are set out in a fixed-price quote.
- Installation goes ahead around the business.
- The system is commissioned and maintenance can be arranged.
Before we arrive
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Keep pets and children away from the work area
- Make sure someone can let us in at the agreed time

Every quote shows the VAT clearly, with the rate that applies to your job. VAT can differ between homes and businesses and between kinds of work, so we confirm it on the quote. For a fixed-price quote, ring 07833 053749 or email us.

Newgate Street: your questions answered
Can you do commercial air conditioning in Newgate Street?
Yes, Newgate Street is within the area we cover. To start, ring us on 07833 053749 or drop us a line with a few pictures.
Do I need planning permission for air conditioning in Newgate Street?
It comes down to the building and the spot chosen for the outdoor unit. Around 7 listed entries sit within 0.5 miles of central Newgate Street. An air-to-air system used for heating as well as cooling can be permitted development on a house if it meets the conditions, but a cooling-only unit is not covered, listed buildings need consent and conservation areas restrict outdoor units facing a road. Where needed, we check with the local planning authority (for Newgate Street, normally Welwyn Hatfield council).
Do you carry out TM44 inspections?
We are not accredited energy assessors, so we don’t inspect. We help before and after, preparing the system and acting on the report.
Do you work on all makes?
We work with the leading brands, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.
Do you work on commercial properties?
Yes. Homeowners, landlords, agents and businesses all book us across London and the South East. Let us know who the records should go to.
What does F-Gas certified mean?
Anyone installing, repairing or servicing the refrigerant side must be qualified, and their company certified. It’s worth checking before booking, and we’re happy to show ours.
Which accreditations do you hold?
We’re an F-Gas certified company, with NICEIC approval for electrical work and MCS certification for heat pumps. We’re also Checkatrade members.
