Choose a garden renovation contractor by comparing relevant work, a written specification and a clear delivery plan. Photographs and a low price are not enough. Establish who manages the project, what is included and how changes will be agreed before accepting the proposal.

Give everyone the same brief
Identify features to retain, items to remove and what the finished garden must do. Describe drainage problems, access and materials. Someone pricing a patio and lawn is not quoting the same job as someone including retaining walls and soil improvement. Consistent information makes differences between quotations meaningful.
Ask for comparable examples
Citizens Advice’s current England guidance recommends two or three recent examples of similar work and written quotes from at least three traders. These are comparison recommendations, not satisfaction statistics. Ask what the contractor installed and speak to customers about communication, drainage and how the garden has aged.
Discuss the construction you cannot see
Ask about excavation, sub-base preparation, wall foundations, drainage and soil beneath new turf. Find out how trees and planting areas will be protected from machinery. For major level changes, establish who designs retaining structures. An attractive paving photograph does not show whether the foundations were correctly specified.
Verify identity and insurance
Obtain the business identity and a reliable contact for the person responsible. Check claimed memberships directly. Ask for appropriate insurance evidence and confirm cover remains current during the work. Establish which qualified specialists handle electrical installations and structural design instead of assuming the same person performs every task.
Read the quotation for exclusions
Look for quantities, material ranges, preparation, disposal and finishing. Check VAT, delivery, skips and repair of access surfaces. Ask what “prepare ground” actually includes. Determine whether the document is a fixed quotation or an estimate containing allowances before accepting it. A vague cheap total can conceal work that another proposal includes.
Agree payments and communication
Tie payments to clear stages and keep receipts. Require evidence, pricing and approval before additional work. Establish who will attend, whether subcontractors are used and who answers questions. Agree hours, storage, security and separation from pets or children. Narrow access in Gloucester may affect neighbours through deliveries and shared routes.
Specify handover and aftercare
Request care instructions, relevant certificates and warranty terms. Clarify who waters newly laid turf and establishes plants. Agree how outstanding items will be recorded and corrected. A guarantee needs defined coverage and an identified provider; a verbal promise of a trouble-free garden is difficult to assess.
Use a site meeting to test the proposal
Ask each shortlisted contractor to explain the difficult parts of the site in plain language. How will excavated material leave the garden? Where will water from the new surface go? What happens if the existing ground is unsuitable? A useful answer describes the proposed approach and any uncertainty, rather than promising every detail will be easy. Take notes and ask for important assumptions to appear in the quotation. The meeting should improve your understanding of the project, not merely produce a price.
Make a fair comparison of value
Compare proposals in a simple list: preparation, materials, drainage, access protection, disposal, finishing and aftercare. Mark missing details and ask for clarification before choosing. A cheaper quote may omit work, while a more expensive one may include features you do not need. Resolve those differences by aligning the scope. Also consider whether communication has been reliable and whether realistic timings have been explained. Choosing on documented value helps avoid paying twice when essential work was excluded from the initial agreement.
Summary
Choose a contractor whose evidence, specification and communication fit the project. Use your written brief to discuss a renovation with ALG Gardening And Landscaping Ltd and assess the proposed work as carefully as its total price.
