Electronics Companies in Leicester: 52 Active Firms (2026)
Electronics manufacturers in Leicester design and assemble components, devices and control systems for specialised UK supply chains.
Purchasing usually sits with engineering, operations, quality and procurement teams that need dependable assemblies for regulated or specialist equipment. The centre of gravity is B2B: industrial equipment makers, controls integrators, instrumentation suppliers and other knowledge-intensive buyers rather than high-volume consumer channels. Engagements tend to start with design-for-manufacture input, testing or low-volume assembly, then move into repeat production where documentation, traceability, conformity marking and environmental obligations are part of the commercial relationship. The more attractive suppliers are those able to bridge engineering judgement and production discipline, not merely populate boards or box-build to a drawing.

Leicester has 52 actively trading electronics manufacturers, a compact local cohort rather than a broad mass-manufacturing base. Reported employment across the group is 844 people, suggesting a market weighted towards specialist workshops and mid-sized production teams. Only 3 companies report turnover above £5M, so the revenue-ranked upper end is narrow. Formation activity also looks modest, with 3 firms incorporated since 2022. That mix points to a mature local supplier base serving repeat technical demand, with relatively few new entrants or visibly larger manufacturers in the city-level cohort.
Market access is shaped by product-safety, environmental and conformity regimes rather than a single sector licence. Electrical and electronic equipment can fall under rules on hazardous substances, electrical safety, electromagnetic compatibility and radio equipment, depending on what is made and how it is sold. In-scope manufacturers need technical documentation, declarations of conformity, required labelling and the correct conformity marking, with OPSS enforcement sitting behind parts of the regime. Waste obligations add another layer: organisations placing electrical and electronic equipment on the UK market may need producer registration, with the compliance route varying by volume.
Growth appears more likely to come from deeper roles in specialist supply chains than from a shift into commodity consumer production. Buyers in regulated equipment, controls and instrumentation tend to value continuity, documentation and testing capability, which favours firms that can keep engineering and production close together. Compliance pressure may raise the cost of casual market entry, while also giving established suppliers a reason to formalise processes and evidence trails. Consolidation may remain selective, as the cohort contains many businesses whose value sits in customer relationships, technical know-how and low-volume production habits rather than in broad national distribution.

Key facts
About 5% of the trading cohort reports turnover above £5M (3 of 52 firms) — the rest sits below that revenue band.
5% of the cohort was incorporated since 2022 (3 firms), so a sizeable share is in its first few filing cycles.
Many types of electrical and electronic equipment in GB and NI fall under the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment Regulations 2012, with OPSS enforcing documentation, Declaration of Conformity, labelling and conformity-marking duties.
Organisations placing more than 5 tonnes of EEE on the UK market must join a producer compliance scheme; those below 5 tonnes can register as small producers.
UK electronics value added rose from £4.1 billion in 2000 to £16.1 billion in 2024, a 5.8% CAGR compared with 1.6% for UK manufacturing overall.
Electronics and electrical equipment together account for 10% of UK manufacturing value added and 13% of UK manufacturing exports, alongside trade deficits of £29 billion for electronics and £16 billion for electrical equipment.
UK electronics ranked fifth among the G7 plus China by 2022 value added, at US$18 billion, behind China, the USA, Japan and Germany.

How Leicester Electronics companies work and how to sell to them
What they do
Revenue usually comes from build-to-order manufacturing, test, rework, prototyping and repeat assembly rather than one-off product sales. Leicester electronics firms typically price by bill of materials, labour content, test complexity and margin on sourced components, with non-recurring engineering charged separately when design input is needed. Engagements often mix services and physical output: printed circuit board assembly, cable and box-build work, embedded hardware support, inspection, repair and lifecycle management. Smaller jobs may be quoted purchase-order by purchase-order, while repeat programmes tend to move to call-off schedules, framework terms or annual pricing reviews.
Who they sell to
Customers are usually technical organisations that need assemblies inside their own equipment: industrial machinery makers, controls specialists, instrumentation suppliers, lab equipment producers and maintenance providers. Day-to-day evaluation tends to sit with engineering managers, operations leads and quality teams, while procurement manages terms and finance becomes involved when tooling, inventory or credit exposure rises. Most selling is direct and relationship-led, often through referrals or incumbent supplier displacement. Tendering appears more common where public-sector or regulated end customers sit downstream; otherwise qualification samples, audits and supplier questionnaires do much of the work.
What they buy
Most Leicester electronics firms tend to spend first on parts supply, production capacity and evidence: component sourcing, test equipment, calibration, inspection, quality management, document control and traceability. Software pitches usually fit when they reduce quote effort, manage changing bills of materials, connect purchasing with work orders, or make compliance packs easier to produce. Relevant categories include manufacturing planning, inventory control, CRM, finance, quality systems, analytics, cyber security and HR. Services sellers may find demand around technical recruitment, health and safety, product compliance, export paperwork, insurance, accountancy and specialist marketing to engineering buyers.
Why and how to sell to them
Electronics manufacturers tend to evaluate vendors when a new customer programme exposes gaps in quoting, traceability, capacity planning or compliance evidence. Other triggers include a production move, a quality issue, a senior operations hire, new product work, component shortages, or a push into regulated end markets. Outbound messages land better when they are specific to engineering-led manufacturing rather than generic technology adoption. Useful angles include reducing rework, protecting margin on component-heavy jobs, shortening audit preparation, improving delivery visibility for repeat programmes, or helping small management teams control risk without adding administrative load.
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.
