Everything Delta First delivers sits under three disciplines, coordinated by a single account manager so clients deal with one team rather than several contractors.
Delta First was set up to remove the gaps between trades on commercial sites. One point of contact coordinates electrical, mechanical and fabric work; statutory compliance dates are tracked for every client site and documented before deadlines; and reactive faults are handled by regionally deployed engineers rather than a national call centre. We work with facilities managers, estates teams, landlords, NHS trusts, schools, local authorities and business owners who want a single accountable maintenance partner.
Whether you need a one-off repair, an EICR programme or a full planned maintenance contract, we're happy to discuss your site and provide a free, no-obligation quotation.
