Our LG installation process, step by step
1. Free LG survey and heat-load calculation
We measure glazing, orientation and room volume to size the LG unit correctly — oversizing causes short-cycling and poor dehumidification.
2. Fixed-price design and quote
You get unit models, pipe routes, condensate route and outdoor unit position in writing, with VAT included and no hidden extras.
3. First-fix installation
Brackets, refrigerant pipework, drainage and the electrical supply go in with dust sheets down and floor protection throughout.
4. Pressure test, vacuum and charge
Nitrogen strength test, evacuation to below 500 microns and weighed-in R-32 charge — the step most warranty claims hinge on.
5. Commissioning and F-Gas certification
Performance readings, F-Gas record, Part P electrical certificate and LG warranty registration completed the same day.
6. Handover and aftercare
We show you the controls and app, then set an annual service to keep the 5-year LG warranty valid.

LG air conditioning installation — FAQs
How much does LG air conditioning installation cost?
A single-room LG wall-split system starts at £1,750 fully installed, including the unit, pipework, electrical connection, commissioning and certification. Multi-split systems serving 2–4 rooms typically run £4,500–£8,500, and commercial cassette or ducted systems are priced per zone after a site survey.
Are you LG approved installers?
We are F-Gas certified and REFCOM registered, and we install and register LG equipment as part of the manufacturer's installer scheme. That registration is what unlocks the extended 5-year equipment warranty on your system.
What warranty comes with a LG system?
5-year parts warranty on registered systems. On top of that, our own installation carries a 5-year parts and labour warranty. Warranty cover requires correct commissioning and an annual service, both of which we can handle.
Can I get LG air conditioning installed in my home?
Yes. LG domestic wall-split and multi-split systems are suitable for bedrooms, living rooms, home offices and loft conversions. Every installation is quoted fixed, in writing, before work begins.
How long does a LG installation take?
A single LG wall-split is normally completed in one day. Multi-split systems serving several rooms take two to three days, and commercial installations are programmed after the survey — often out of hours to protect trading.
Do you service and repair LG air conditioning?
Yes — we service, regas and repair LG equipment whether or not we installed it, and annual servicing keeps the manufacturer warranty valid.
