Agree a staged payment schedule tied to completed milestones, and hold a small retention until snagging is done. - Get it in writing: an itemised quote with scope, materials, start and finish dates, and how any changes (variations) will be priced. - Be wary of a cash-only price or pressure to start tomorrow. Both are red flags for an unaccountable job. - Ask to see a portfolio of completed work like yours, plus recent references you can contact. - Check the credentials and registrations that matter for this work, and that they are current. ## Contact - Phone: 07307 246676 --- Source: MyTrustedTraders, https://mytrustedtraders.com/traders/a2z-construction-heating-ltd Real public evidence only: every figure traces to a named source, and reviews are cross-checked across 2 review sources.
