Hiring A Garden Designer For Your Outdoor Space

A garden redesign is often triggered by a life event — a new home with an overgrown plot, a growing family needing more usable outdoor space, or a long-postponed project that finally has the time and budget behind it. For UK homeowners considering a significant garden overhaul, the line between a garden designer and a landscaper is frequently blurred, and the distinction between design fees and build costs is rarely made clear at the outset.

Key points

• The Society of Garden Designers (SGD) is the UK's main professional body for residential garden designers; full members (MSGD) must demonstrate professional competence and hold relevant qualifications or significant experience.
• Garden designers produce plans and specifications; landscaping contractors carry out the physical build — these are usually separate services with separate costs.
• Building Regulations Approved Document B does not apply to soft landscaping, but may apply to proposed structures, raised walls above certain heights, and changes that materially affect surface water drainage.
• RHS Level 3 and Level 4 qualifications in Garden Design are widely held by practising designers and indicate a foundation of horticultural and design training.
• Tree Preservation Orders (TPOs) can restrict work to trees on or near your plot; always check with your local planning authority before removing or significantly pruning any established tree.

Garden designer vs landscaper: what is the difference?

These two roles are frequently confused, and many homeowners are unsure which they actually need. In practice they serve distinct purposes — and for a complex project, you may need both.

Many landscapers offer design-and-build services, but the depth of design varies considerably. If you have a complex or high-value project, commissioning a designer separately — then using their drawings to get competitive quotes from multiple contractors — often produces better value and results.

Do you need a garden designer?

Use this to decide which route suits your project:

• Choose a garden designer if you want a cohesive outdoor space planned to your brief, have a meaningful budget, or have a difficult plot (sloped, overshadowed, or irregularly shaped) that needs careful design thinking.
• Choose a design-and-build landscaper if your project is straightforward — a new patio, replacement lawn, or simple boundary — and you prefer a single point of contact.
• Choose a garden designer and a separate contractor if you want competitive quotes from multiple builders all working to the same specification.
• Consult a landscape architect if your project involves planning applications, complex drainage, significant retaining structures, or listed building curtilage.

What does the process involve?

A typical residential garden design project follows broadly this sequence:

1. Initial consultation — usually a paid visit; the designer surveys your garden, discusses your brief, lifestyle, maintenance preferences, and budget.
2. Measured survey — accurate dimensions, levels, soil conditions, sun and shade patterns, and existing features are recorded.
3. Concept design — initial layouts showing zones, structures, planting areas, and materials, reviewed together before progressing to detail.
4. Detailed design — scaled plans, planting schemes, materials schedules, and construction details for any hard landscaping.
5. Tender and contractor selection — some designers help you obtain and compare quotes from contractors using their drawings.
6. Site visits during construction — optional but valuable where planting sequences or bespoke details need oversight.

Not all designers offer every stage. Agree the full scope of work — and what deliverables you will receive — in writing before any work begins.

What qualifications should you look for?

There is no statutory requirement to hold specific qualifications to call yourself a garden designer in the UK, so checking credentials matters more than in regulated professions.

• SGD membership (MSGD) — requires demonstrable professional competence and is the clearest independent signal of seriousness and accountability.
• RHS Level 3 Diploma in Horticulture or RHS Level 4 Diploma in Garden Design — widely held by practising residential designers.
• Landscape Institute membership — relevant for landscape architects working on larger or more technically complex projects.

Always ask for a portfolio of recent residential projects, references, and evidence of professional indemnity insurance. Professional indemnity insurance protects you if a design error leads to financial loss.

What to ask before hiring a garden designer

Before appointing a designer, ask:

• What is included in your fee — site survey, concept design, detailed plans, planting schedule, contractor tender support?
• Who owns the design drawings, and can I use them to obtain competitive quotes from contractors of my choice?
• Do you hold professional indemnity insurance, and what is the level of cover?
• Can you provide references from recent residential projects of a similar scale?
• Do you work exclusively with specific contractors, or are you independent?
• Will you visit site during the build, and at what additional cost?
• What assumptions are you making about soil type, drainage, and existing utilities?
• Is VAT included in your quoted fee?

Homeowner checklist: before your first meeting

Preparing the following before your initial consultation will make the meeting more productive and the brief more accurate:

• A rough budget range for design fees and build costs separately — most designers will ask for both
  
• A list of how you want to use the garden (entertaining, children's play, growing food, low maintenance)
  
• Photographs of gardens you like and dislike
  
• Any known constraints: neighbour boundaries, party wall agreements, protected trees, drainage problems
  
• A copy of your property's title plan if boundaries are disputed or unclear
  
• Any planning restrictions in your area (conservation area, listed building curtilage)
  
• Utility locations if known (gas, water, surface drains)
  
• Notes on any previous planning or building control approvals for existing structures
  

When to get professional help

A garden designer is the relevant professional for design work, but some situations require additional specialist input:

• If a proposed wall, pergola, or structure is close to a boundary, check permitted development limits or consult a planning professional before proceeding.
• If the project involves a material change to drainage or a significant increase in hard surfacing, Building Regulations or a drainage assessment may be required.
• If there are protected trees (subject to a Tree Preservation Order) on or adjacent to your plot, contact your local planning authority before any work begins near them.
• If you are within a conservation area or the property is listed, check whether garden structures or hard landscaping changes require heritage or planning consent.

Frequently asked questions

Do I need planning permission for garden work in the UK?

Most garden work — patios, planting, and lawn areas — does not need planning permission under permitted development rights. However, structures such as outbuildings, raised walls above certain heights, and works in conservation areas or listed building curtilage may require consent. Always check with your local planning authority if you are unsure about your specific project.

How much does a garden designer cost in the UK?

Design fees vary by project scope and designer experience. A planting plan may cost £300–£800; a full garden design with construction drawings typically ranges from £1,500 to £5,000 or more. Build costs are separate and additional. Indicative UK costs, last reviewed 2026-05-31. Always obtain at least three quotes.

How long does a garden design project take?

From initial consultation to final drawings, expect four to twelve weeks depending on project complexity and the designer's workload. Build programmes vary: a patio and planting scheme might take one to two weeks, while a full garden transformation with hard landscaping can run to several months.

What is the difference between an SGD member and any garden designer?

SGD (Society of Garden Designers) membership requires demonstrable training, professional experience, and a commitment to standards including professional indemnity insurance. Non-members may be equally skilled, but membership provides an independent check on credentials and access to the SGD's complaints process if problems arise.
