What affects the cost
Cost depends on plot size, whether it's regular maintenance or a one-off project, materials (paving type, decking vs artificial grass), and access for machinery or skips on larger jobs. A garden clearance before a redesign is often quoted separately from the landscaping work itself.
Guarantees on landscaping work
Hard landscaping (patios, walls, decking) commonly comes with a workmanship guarantee, typically shorter than a building trade's (often 1-2 years). Planting generally isn't guaranteed the same way since plant survival depends on aftercare, weather and site conditions beyond the installer's control.
Three steps to hiring the right gardener
First, ask to see photos of similar completed work, ideally local gardens. Second, for larger projects, get a written quote specifying materials and scope. Third, ask about public liability insurance, particularly for any work involving power tools, ladders, or structural landscaping.
Garden drainage and irrigation
Poor drainage (waterlogging after rain, a consistently boggy patch) is often fixable with a French drain or soakaway rather than needing a full garden regrade — worth getting properly diagnosed before assuming the whole garden needs releveling. Irrigation systems are more relevant for larger gardens or specific planting that needs consistent watering.
Landscaping work and home insurance
Structural garden work (retaining walls, significant regrading) can occasionally affect drainage near a property in ways insurers care about — worth checking with your insurer for anything substantial, and keeping any specification/photos from the work done in case they're needed later.
Background checks and insurance
Since gardening isn't gated by a mandatory certification, checking trading history, reviews referencing specific local jobs, and confirming public liability insurance matters more than for trades with formal registration bodies — ask to see proof of insurance for anything beyond routine maintenance.
How many quotes should you get?
Three is reasonable for a one-off landscaping project. For ongoing maintenance, it's often worth trying a gardener for an initial visit or two before committing to a regular contract, since fit and communication matter as much as price for an ongoing relationship.
APL, BALI and HTA, what they mean
The Association of Professional Landscapers (APL) is a TrustMark scheme operator for landscaping. BALI (British Association of Landscape Industries) and the HTA (Horticultural Trades Association) are the other main trade bodies. None of these are legally required, and membership varies across the industry — worth asking which, if any, a gardener holds rather than assuming it's standard.
