Main Contractors FAQs
Can you tender against drawings and a programme?
Yes — send architectural drawings, the construction programme and any spec docs. We return a priced package, lead-times and a draft programme alignment within a few working days.
Do you provide site-specific RAMS and method statements?
Yes — site-specific RAMS, method statements, COSHH and lift plans are issued before mobilisation and updated as the programme evolves.
What accreditations do you hold as a subcontractor?
CHAS Gold, Constructionline Gold, FENSA, SSIP and £10m public liability. We're set up to work under principal contractors on CDM-notifiable projects.
Can you mobilise quickly for snagging or remedial works?
Yes — we routinely pick up glazing snags, hardware remedials and small defect-period works on handed-over schemes with a fast turnaround.
Do you offer aftercare and warranty support post-handover?
Yes — all installs come with manufacturer-backed warranties, and we handle defect-period call-outs directly with your aftercare team.
