How to Choose a Landscaper in Sussex: Design, Levels, Drainage and a Build That Works

If you need a landscaper in Sussex, compare how each contractor plans the levels, drainage, materials and sequence of the whole garden before you compare the visual finish or headline price.

A garden can look excellent in a quotation image and still become frustrating if water sits against the house, paths are awkward, lawn levels do not meet paving properly or planting was treated as an afterthought.

Start with how you want to use the garden

Before talking about products, describe the outcome.

You might want:

• a low-maintenance family garden;
• a safer rental garden;
• more usable seating space;
• better access;
• a lawn that drains properly;
• privacy planting;
• a new patio;
• easier maintenance;
• space for children or pets;
• a complete redesign.

That gives the landscaper something more useful than:

“Can you make it look nicer?”

Separate design decisions from construction decisions

Some landscapers offer design as part of the service.

Others are strongest when working from an agreed plan.

Clarify whether the quote includes:

• measured survey;
• layout drawing;
• material specification;
• planting plan;
• lighting/irrigation coordination;
• revisions.

If you are still changing the layout while the build is underway, expect cost and programme changes.

A clear design before excavation starts is usually cheaper than designing with a digger already on site.

Levels should make sense before anything is paved

Ask the landscaper to explain the proposed finished levels.

Consider:

• house thresholds;
• damp-proof course;
• steps;
• slopes;
• neighbouring levels;
• lawn;
• patio;
• drainage channels;
• gates.

One small change in height can affect several areas.

If a patio is being raised, ask how that affects door thresholds and drainage.

If a lawn is being lowered, ask where excavated soil goes.

Drainage is a design feature, not an afterthought

Water needs somewhere to go.

Ask what happens during heavy rain.

Depending on the project, the answer may involve:

• falls across paving;
• permeable areas;
• channels;
• soakaways where suitable;
• existing drainage;
• planted areas.

Do not accept a vague assumption that water will “find its way away”.

For front gardens and driveways, planning rules around impermeable surfacing can also matter.

Compare material specifications properly

“Porcelain patio” or “new lawn” is not a full specification.

For hard landscaping, ask about:

• paving product/size;
• sub-base;
• bedding;
• jointing;
• edging;
• steps;
• drainage details.

For lawns:

• turf or seed;
• soil preparation;
• levels;
• drainage;
• establishment period.

For planting:

• plant sizes;
• quantities;
• compost/soil;
• stakes;
• mulch;
• watering/aftercare.

Two quotes may describe the same-looking outcome while using very different build-ups.

Access can change the project economics

Tell the landscaper about:

• narrow side access;
• steps;
• no rear access;
• shared driveways;
• parking restrictions;
• neighbour access;
• distance from road to garden.

If a mini digger cannot reach the garden, excavation and waste removal may become much more labour-intensive.

That should be understood before the price is agreed.

Waste and excavation should be visible in the quote

Garden transformations can generate large quantities of:

• soil;
• old paving;
• concrete;
• timber;
• vegetation.

Ask:

• what is being removed;
• how it is removed;
• whether skips/grab lorries are included;
• whether disposal is included.

Do not assume “clear site” means the same thing to everyone.

Think about sequence

A typical landscaping project may include:

1. clearance;
2. excavation;
3. drainage/services;
4. walls/structures;
5. hard landscaping;
6. soil preparation;
7. lawns;
8. planting;
9. final clean/aftercare.

If garden lighting, irrigation or outdoor electrics are planned, coordinate those before finished paving makes routes difficult.

Planning and Building Regulations can still appear outdoors

Many ordinary garden projects do not need formal approval.

But work involving:

• significant structures;
• retaining elements;
• drainage;
• electrical work;
• buildings;
• changes near boundaries;

can introduce additional requirements.

Ask the contractor what they believe applies and verify anything significant through the appropriate authority or professional.

Do not assume “it is only in the garden” means no rules can apply.

Landlords: prioritise maintainability

For a rental property, a high-maintenance garden can become an operational problem.

Consider:

• simple planting;
• durable paving;
• accessible bins;
• manageable hedges;
• robust lawn or alternative surfaces;
• clear maintenance responsibility.

A beautiful planting scheme that needs specialist pruning every month may not be the best choice for the property.

Landscaper or gardener?

For construction and redesign, start with landscapers across Sussex.

For ongoing mowing, weeding and pruning, gardeners may be a better fit.

Some projects will need both: landscaper for the build, gardener for long-term maintenance.

Levels and water movement should be decided before the finishes

The most expensive landscaping mistakes are often hidden beneath attractive paving or turf.

Ask where rainwater is intended to go.

A competent plan should consider:

• falls away from buildings;
• existing drains;
• surface-water routes;
• lawn levels;
• patio thresholds;
• retaining edges;
• raised beds;
• neighbouring ground levels.

If the proposed design creates a low point beside the house, ask how that water will escape.

The finished garden should not simply look level in photographs; it should manage water sensibly.

Separate design decisions from construction decisions

You may still be choosing planting, paving colours and furniture while the contractor needs firm answers about excavation and drainage.

Split the project into two layers.

Design decisions include layout, style, planting and finish.

Construction decisions include levels, retaining structures, sub-base, drainage and access.

The second group usually needs resolving first.

Changing paving colour late may be manageable.

Changing the finished levels after foundations, drains and retaining work are built is not.

Using TradeKind

You can browse Sussex landscaper profiles or post the project.

A useful brief might say:

“Rear garden in Worthing, approx. 12 x 8m. Replace old patio, improve drainage, new lawn and low-maintenance planting. Side access approx. 800mm. Looking for design input and full installation.”

That gives businesses enough context to judge whether the project suits them.

Final comparison

Before choosing, ask:

• Is the design clear?
• Are levels understood?
• Where will water go?
• Are material build-ups specified?
• Is access practical?
• Is waste included?
• Who handles specialist trades?
• What happens if ground conditions differ?
• Is planting/aftercare included?
• What is excluded?

Good landscaping is not just an attractive finish. It is a garden that still works after the contractors have left.
