Air Conditioning Contractors London, Surrey & Surrounding Areas

Aboveboard Group covers all of London, Surrey, and the South East. We are based in Sutton, Surrey, which gives us excellent access to Central London, the Home Counties, and the wider South East region. We regularly work in Sutton, Croydon, Kingston, Guildford, Woking, Epsom, Reigate, Redhill, and all surrounding towns. Our day-rate labour service extends nationwide for larger projects.

Yes, if you are anywhere in Surrey — including Sutton, Guildford, Woking, Epsom, Reigate, Redhill, Dorking, Leatherhead, Cobham, Esher, or any surrounding town — we are your local air conditioning installation contractor. Being Sutton-based means we can respond faster than London-based contractors and offer competitive rates without travel surcharges across most of Surrey.

Yes, temporary AC labour supply is one of our core services across London. We provide individual engineers, pairs, and full installation teams on a day-rate basis. Our engineers are F-Gas certified, CSCS-registered, and experienced in commercial environments. We have placed engineers on projects in Central London, the City, Canary Wharf, and Greater London boroughs within 24 hours.

We install all major types of commercial air conditioning systems including VRF (Variable Refrigerant Flow), VRV (Variable Refrigerant Volume), multi-split systems, cassette units, wall-mounted splits, ducted systems, and close control units for server rooms. We work with leading manufacturers including Daikin, Mitsubishi Electric, Toshiba, Hitachi, and Samsung.

Yes, we offer tailored maintenance contracts for commercial air conditioning systems across London and Surrey. Our maintenance programmes include filter cleaning and replacement, coil cleaning, refrigerant level checks, electrical connection inspection, control system testing, and detailed performance reports. We offer annual, bi-annual, and quarterly servicing with 24-hour emergency breakdown cover.

For our maintenance contract customers, we offer 24-hour emergency breakdown response across London and Surrey. Our Sutton base gives us rapid access to most areas within the M25. For non-contract customers, we aim to respond within 48 hours. Our engineers carry common spare parts to maximise first-visit resolution rates.

Every Aboveboard Group engineer holds current F-Gas certification (Category 1 or equivalent), CSCS registration, and relevant health and safety qualifications. We carry full public liability insurance (£10m+) and employer's liability insurance. All work is carried out in compliance with F-Gas regulations, Building Regulations Part L, and industry best practices.

Yes, we regularly act as a specialist subcontractor for main contractors and construction companies on commercial builds, fit-outs, and refurbishments. We provide full design-and-build AC packages, labour-only packages, or day-rate engineer supply. We produce full RAMS, method statements, quality packs, and commissioning documentation to meet main contractor standards.

Price work means we quote a fixed price for a defined scope of AC installation work — ideal when you have clear specifications and want cost certainty. Day rate labour means you hire our engineers by the day, giving you flexibility to scale labour up or down as your programme demands. Many clients use both: price work for defined packages and day rate for variable labour needs.
