Established in 1995, the APL is a specialist group of the Horticultural Trades Association (HTA), and represents landscapers who have met a required standard of professionalism.

Members of the Association are registered with the government endorsed TrustMark scheme and are regularly inspected and agree to follow our Customer Charter. All APL members also hold appropriate insurances and have traded for a minimum of two years.

Landscape businesses can only join TrustMark through the Association of Professional Landscapers (APL). The APL carries out annual checks to ensure that the company meets certain standards.

These include checks on the company’s technical competence, trading record and legality. These checks include actual visits by independent assessors at real client’s projects and to view actual company documentation such as insurance certificates etc.

The APL only awards the TrustMark certificate if they are satisfied that they meet the Government endorsed standards.

TrustMark monitors the scheme operator to make sure that standards are being maintained.

APL are proud to be the only landscaping association that is an ‘approved scheme operator’ for TrustMark for the garden landscaping, fencing and patio and driveways sectors.
