A cheap install is the most expensive kind of air conditioning you can buy. Poor pipework brazing, undersized cabling and guessed heat loads all show up eventually — usually on the hottest day of the year, when refrigerant leaks, compressors trip on high pressure and rooms simply will not cool. We build every system to last 15+ years by combining CIBSE-grade design, F-Gas certified engineering and equipment specified for the actual room, not for the invoice.
Every proposal is a written, itemised, fixed price after a proper site survey — never a phone estimate. You see the equipment model numbers, refrigerant type, pipe routes, electrical scope, condenser location and lift or access requirements before you commit. If the scope changes on site, you approve any variation in writing before we lift a tool. Roughly 92% of our quoted projects complete at the original figure; the other 8% involve customer-requested upgrades, not surprise extras.
Every engineer on your job is directly employed, DBS-checked, uniformed and carrying a City & Guilds 2079 F-Gas card. We do not white-label work to a rotating pool of contractors, which is why we can offer a genuine 5-year parts warranty and a 12-month workmanship guarantee that we actually honour. The person who quotes your project is accountable for how it runs on site — and their name is on the commissioning certificate.
£10m public liability, £5m professional indemnity, REFCOM F-Gas company certificate, NAPIT Part P registration and Gas Safe registration for hybrid systems. Documents are shared with your facilities team or main contractor before we set foot on site.
A correctly sized R-32 inverter split delivers a seasonal efficiency ratio (SEER) between 6.5 and 8.5 — meaning every 1 kWh of electricity produces 6.5 to 8.5 kWh of cooling. On heat-pump duty, coefficients of performance (COP) sit between 3.5 and 4.5 in UK winter conditions, which beats gas heating on marginal pence-per-kWh once the standing charge and carbon price are included. We size for the actual peak load, not a rule-of-thumb, so units modulate at 20–40% output most of the time — quieter, cheaper and dramatically kinder on the compressor.
Inside the M25 we normally survey within 3–5 working days and install within 2 weeks of order. Nationally, allow 7–14 days for install once equipment lands. Evening (18:00–02:00) and Sunday shutdown slots are available for occupied premises at a transparent 10–20% uplift — itemised, never buried in the total.

Rule-of-thumb kW by room area
Worked example
A 5m × 4m × 2.4m lounge = 48 m³ → estimated load 1.92 kW → recommended 2.5 kW wall-mounted split.
Size each room, we sum the indoor capacity.
Multi split outdoor units are sized by diversity factor — a designer confirms the final outdoor kW.

Trusted brands only: Daikin, Mitsubishi Electric, Panasonic, LG, Samsung, Toshiba.
From wall-mounted split systems to external condenser units, we design and install every component to manufacturer specification and BS EN 378.

Wall-mounted split AC units are the most popular choice for London homes and flats. We install ultra-quiet inverter indoor units — as low as 19 dB — that blend cleanly with modern interiors while delivering precise cooling and heating through reverse-cycle heat pump technology.

Proper outdoor condenser placement is critical for efficiency, noise compliance and longevity. We mount units on vibration-isolating brackets, run insulated refrigerant line sets through discreet ducting, and ensure minimum clearances for airflow and maintenance access.

Our end-to-end AC installation service covers everything from heat-load survey and unit specification to final commissioning and warranty registration. Every system is pressure-tested, evacuated to 500 microns, charged to manufacturer weight, and signed off with a BS EN 378 commissioning certificate.
Every engineer on our register holds current F-Gas certification (C&G 2079). This is not optional paperwork — it is a legal requirement for anyone installing, servicing or decommissioning equipment that contains fluorinated refrigerants.
Certified engineers are qualified to handle, recover and charge refrigerants such as R-32 and R-410A. They understand leak-detection protocols, safe evacuation procedures and the legal record-keeping required under EU F-Gas Regulation 517/2014.
It is a criminal offence in the UK for an uncertified person to work on stationary refrigeration, air conditioning or heat-pump equipment containing F-gases. Using a certified installer protects you from liability and invalid insurance claims.
Fluorinated gases have a global warming potential thousands of times higher than CO₂. Certified installers use recovery cylinders, vacuum pumps and electronic leak detection to prevent venting and minimise climate impact.
Manufacturer parts warranties and building-insurance policies typically require proof of F-Gas certified installation. We provide a signed commissioning certificate and F-Gas log sheet for every system we install.
Verification
All engineers carry photo ID and current F-Gas cards. You can verify any installer's credentials on the official DEFRA F-Gas register before work begins.
"Survey to commissioning in under a fortnight. The engineers were immaculate — dust sheets everywhere, and they left the flat cleaner than they found it."
"Quoted three companies. Clearest on price, only firm that walked through the F-Gas record with me, and the fixed quote didn't move by a penny."
"Multi-split across three bedrooms. Cooler nights, lower bills than expected. Independent control on every room is worth every pound."
