Aerospace & Defence Companies in Brighton: 32 Active Firms (2026)
Aerospace and defence companies design, manufacture and support aircraft systems, components and dual-use technologies around Brighton.
Buying centres tend to sit with engineering, programme, quality and compliance teams rather than general procurement alone. Around Brighton, the buyer shape is usually commercial aviation, defence, government or regulated supply-chain customers that need certificated parts, integration support, maintenance services, security tooling or specialist engineering evidence. Engagements are typically project- or framework-led, with documentation, traceability and assurance carrying as much weight as price. The most plausible suppliers are engineering-led firms selling into complex procurement processes, from smaller component and support providers to mid-market contractors serving prime contractors and public-sector channels.

Brighton has 32 actively trading aerospace and defence companies, a compact cohort by UK standards. Reported headcount totals 501, pointing to a local footprint made up mainly of specialist employers rather than large production estates. Only a small subset sits above the lower mid-market revenue band, so most commercial conversations are likely to involve technical fit, certification burden and access to regulated customers rather than broad market reach. The result is a supplier base that looks useful for targeted mapping, but too small to treat as a self-contained regional cluster.
Civil aviation work falls under CAA safety and certification oversight where relevant, while ADS has pointed to the CAA’s expanded rulemaking and certification role. Alignment with EASA requirements and closer FAA cooperation matter where Brighton suppliers want access to international aircraft programmes. Defence, security and dual-use goods sit in a different control environment: GOV.UK guidance requires exporters to check the consolidated control list and seek Export Control Joint Unit licences where goods or technology are controlled, end-use concerns arise, or sanctions apply. Unlicensed exports of controlled items carry criminal liability.
The Brighton cohort appears more likely to evolve through supply-chain depth than through the emergence of large prime contractors. New formation has been limited, and the commercially mature firms appear to be those with repeatable compliance processes, auditable documentation and relationships with regulated buyers. Regulatory pressure may favour suppliers that can absorb certification, export-control screening and technical assurance work without slowing delivery. Consolidation is plausible where smaller engineering teams need broader bidding capacity, but the market still looks too specialist and procurement-bound for simple volume-led scaling.

Key facts
About 12% of the trading cohort reports turnover above £5M (4 of 32 firms) — the rest sits below that revenue band.
6% of the cohort was incorporated since 2022 (2 firms), so a sizeable share is in its first few filing cycles.
The CAA oversees civil aviation safety and certification, while EASA alignment and closer FAA cooperation matter for aerospace market access.
Defence and dual-use exports sit under UK strategic export controls, including the Export Control Act 2002 and Export Control Order 2008.
Exporters must apply to the Export Control Joint Unit for licences where items are controlled, end-use concerns arise or sanctions apply.
GOV.UK reported UK defence orders worth £13.2 billion in 2024, up from £11.9 billion in 2023 and against a 2020–2024 annual average of £9.3 billion.
Aerospace products accounted for 53% of UK defence export orders over 2020–2024, while Europe accounted for 38.4% of UK defence export value over the same period.

How this list is built
Data sources
This list is built from UK Companies House filings, XBRL accounts data, and semantic analysis of each company's public website. Revenue and headcount figures come from the most recent filed accounts; where the company has not filed, values are estimated using a model trained on filed history and peer benchmarks and are labelled as estimates.
Classification
Rather than relying solely on SIC codes, Firmbase classifies each company semantically: the company's website is crawled, an AI model reads what the company actually sells, and the company is placed into the relevant industry and subsectors. SIC codes are used as one signal but not the only one. This means a company that registered under a generic SIC code but pivoted into (for example) fintech is correctly identified as fintech, not as its original SIC category.
Freshness
The underlying company data is refreshed from Companies House continuously; filings appear in the list within days of submission. The curated list ordering is regenerated when the underlying data moves meaningfully (company count changes by more than 5%, a new company enters the top-ranked segment, or the filed-revenue numbers for the top firms change). You can see the last-updated timestamp near the top of the page.
