Who this f-gas certified air conditioning installers service is for
We deliver f-gas certified air conditioning installers for homeowners, landlords, facilities managers and main contractors who need proof that refrigerant work is legally certificated. Typical projects sit in the 2.0 kW single split to 500+ kW VRF band, and every scheme is designed by an F-Gas certified engineer against a full CIBSE Guide A heat-load calculation — never a rule-of-thumb watts-per-square-metre guess.
We cover the whole UK from London-based engineering hubs, with same-week surveys inside the M25 and 7–14 day lead times nationally. All work is delivered by directly-employed engineers rather than subcontractors, so the person who quotes your job is accountable for how it is installed and commissioned.
System types we recommend
F-Gas certification applies to every system that contains fluorinated refrigerant — wall splits, multi-splits, cassettes, ducted units, VRF and air-source heat pumps. We install, commission, leak-test and decommission all of these under our Category I personnel certificates and company REFCOM registration.
Every specification is written against your actual building fabric, occupancy pattern and electrical capacity. We do not resell a single manufacturer — the design drives the equipment choice, not the other way around. If your incoming supply is constrained, we flag it at survey and offer a phased approach or a load-shedding controller rather than pretending the problem does not exist.
The survey, design and installation programme
A senior engineer attends site within 3–5 working days of enquiry. The survey covers heat gains (fabric, solar, occupancy, equipment), electrical capacity, condenser positioning, structural loading, acoustic constraints to neighbours, drainage routes and any planning/landlord constraints. Photos, measurements and load calculations feed into a written fixed-price proposal within 48 hours.
Once awarded, we produce a full drawing pack — pipe routes, electrical schedule, condenser structural loading, refrigerant volume and BS EN 378 risk assessment. Installation runs to a published programme with daily photo updates. Commissioning follows BSRIA BG 49 with a full test-and-balance report, an F-Gas record and manufacturer warranty registration on the day of handover.
Costs, timeline and running expenses
F-Gas Certified Air Conditioning Installers typically starts at £1,650 per room for a compact single-zone scheme. Multi-zone and specialist projects scale with total cooling capacity in kW, condenser positioning complexity and any out-of-hours working requirement. Programme duration is 1–2 days residential, 3–15 days commercial. We quote fixed prices — nothing is added on site without written change control.
A correctly charged, properly commissioned system runs 10–20% cheaper than an undercharged one. Refrigerant undercharge is the single most common cause of poor efficiency in systems fitted by uncertificated installers, and it is invisible without gauges and a commissioning record. Modern R-32 inverter equipment routinely delivers seasonal efficiency ratings (SEER) between 6.5 and 8.5, which is 30–50% better than the R-410A systems installed a decade ago. On heat-pump duty, coefficients of performance (COP) sit between 3.5 and 4.5 in UK conditions — comfortably ahead of gas heating on marginal-cost pence-per-kWh once carbon pricing is factored in.
Compliance, warranties and aftercare
Every installation is notified under Building Regulations Part P (electrical) and Part L (energy) where applicable, and lodged with the appropriate competent-person scheme. Systems containing 5 tCO₂e or more of F-Gas refrigerant require statutory annual leak checks under Regulation EC 517/2014 — we hold the F-Gas company certificate and can act as your Responsible Person, keeping records for HMRC and Environment Agency inspection.
Equipment carries a 5-year manufacturer parts warranty (compressor included) when installed by an accredited engineer. We register the warranty on the commissioning day so there is nothing for you to file. Our installation workmanship carries a 12-month cover-all warranty, and PPM service plans start at £110 per outdoor unit per year — sufficient to preserve manufacturer cover and catch drift before it becomes downtime.
Brands we install and why
We are accredited on Mitsubishi Electric, Daikin, Panasonic, LG and Samsung equipment, and register the manufacturer warranty on the day of commissioning — something manufacturers will only do for certificated installers.
All refrigerant work uses R-32 (GWP 675) as standard, with R-454B (GWP 466) available on request for future-proofing against the F-Gas phase-down schedule. We steer clients away from R-410A (GWP 2088) for any new install — the refrigerant is being progressively withdrawn from supply and top-up costs will rise sharply between 2026 and 2030.
Working around your operation
Downtime is the hidden cost of any air conditioning project. We routinely deliver work in evening slots (18:00–02:00), Sunday shutdowns and staged week-by-week phasing so your day-to-day operation continues unaffected. Overnight and weekend working commands a modest 10–20% uplift which we itemise transparently at quotation.
Dust management, negative-pressure containment and daily photo close-out reports are standard for any works in occupied premises. Where a phased approach is chosen, we deliver temporary cooling (portable spot coolers or hire chillers) to bridge critical zones during the transition — priced separately so you can choose whether the resilience is worth the line item.
Why F-Gas certification is not optional
Under the Fluorinated Greenhouse Gases Regulations, anyone who installs, services, repairs or decommissions equipment containing F-Gas refrigerant must hold a personnel certificate, and the company employing them must hold a company certificate. Handling refrigerant without one is a criminal offence carrying fines for both the installer and, in some circumstances, the site operator.
The practical consequences matter as much as the legal ones. An uncertificated install voids the manufacturer warranty, invalidates many buildings insurance policies, and leaves you without the commissioning record a surveyor or buyer will ask for. Ask any installer for their personnel certificate number and their company REFCOM or equivalent registration before they touch a system — a legitimate installer will send both without hesitation.
What your F-Gas paperwork should contain
On completion you should receive a commissioning sheet showing measured superheat and subcool, the weighed refrigerant charge, ambient and target temperatures, and the electrical readings taken at start-up. Alongside it you should get an F-Gas log book listing the refrigerant type, charge weight in kilograms, the tonnes of CO₂ equivalent and the date the first statutory leak check falls due.
Systems containing 5 tonnes CO₂e or more (roughly 1.7 kg of R-410A or 3.4 kg of R-32) need a leak check at least every 12 months. Systems at 50 tonnes CO₂e or more need automatic leak detection. We set those reminders up for you at handover rather than leaving compliance to chance.
Why choose us for this work
We are F-Gas certified installers with directly-employed engineers, fully insured to £10m public liability and £5m professional indemnity. Every project comes with a fixed price, a written programme, a photo record and a 5-year warranty on equipment plus 12 months on workmanship. We publish real client references on request — not gated behind a form.
Request a quote online and we will book a site survey. Same-week surveys inside the M25, 7–14 day lead times nationally, and a qualified engineer attending the survey rather than a scripted call-centre operator.

Frequently asked questions
How much does f-gas certified air conditioning installers cost?+
Fully-fitted prices start at £1,650 per room. Multi-zone and specialist projects scale with total cooling capacity in kW and installation complexity. All quotes are fixed price — no on-site supplements.
How long does the installation take?+
1–2 days residential, 3–15 days commercial
Do you handle Building Regulations sign-off?+
Yes. Part P electrical work is notified via our NAPIT/NICEIC scheme and Part L energy compliance is documented in the commissioning pack. You receive certificates on the day of handover.
What refrigerant do you use?+
R-32 as standard (GWP 675). R-454B (GWP 466) is available on request for maximum future-proofing against F-Gas phase-down. We do not install R-410A for new schemes.
Do you offer service and maintenance plans?+
Yes — PPM plans start at £110 per outdoor unit per year and include filter cleans, coil disinfection, drain-line flush, refrigerant pressure check and electrical inspection. Statutory F-Gas leak checks are included on qualifying systems.
What warranty applies?+
5-year manufacturer parts warranty on equipment (compressor included) plus 12 months workmanship warranty on our installation. Annual servicing preserves manufacturer cover.
How do I check an installer is really F-Gas certified?+
Ask for the engineer's personnel certificate number and the company's REFCOM (or equivalent) registration number, then check the register. We provide both in writing before any work is booked.
Is F-Gas the same as Gas Safe?+
No. Gas Safe covers natural gas and LPG appliances such as boilers. F-Gas covers fluorinated refrigerants in air conditioning and heat pumps. Air conditioning work needs F-Gas certification, not Gas Safe.
Do I need an F-Gas certificate for a small home system?+
The installer does. A domestic split still contains fluorinated refrigerant, so the engineer must hold a Category I certificate and the company must be registered — regardless of system size.
