Defence & MOD Bid Writing Services

The Ministry of Defence is one of the largest procuring bodies in the UK. Most major requirements are run through Defence Equipment and Support (DE&S), the arms-length body responsible for equipping and supporting the armed forces, while a wide range of services, estate, and logistics work is advertised on the Defence Sourcing Portal and the Find a Tender Service. Crown Commercial Service frameworks also carry defence-relevant lots that many suppliers reach the MOD through.

Winning defence work is rarely about the bid alone. Prime contractors and the MOD itself expect suppliers to hold JOSCAR accreditation through Hellios, to evidence Cyber Essentials Plus and often ISO 27001, and to field personnel cleared to Baseline Personnel Security Standard (BPSS) or Security Check (SC) level. DEFCON contract conditions and DEFSTAN standards then shape how the commercial and technical response must be written. Miss any one of these and an otherwise strong bid is non-compliant before it is scored.

Glaxtons brings BPSS, SC and DV cleared consultants who have written and reviewed defence submissions across estate management, logistics, and technical services, including support on an £85 million MOD estate management engagement. We handle the accreditation groundwork and the response writing together, so the compliance bar and the winning argument are built in the same pass.
