HVAC Refrigeration Companies in Derby: 155 Active Firms (2026)
HVAC refrigeration companies in Derby install, maintain and service heating, cooling, ventilation and cold-chain systems across the metropolitan area.
Buying centres sit mostly with facilities management, estates teams, plant engineers and operations managers, with procurement involved where planned maintenance spans commercial premises, industrial sites or public-sector buildings. The work is field-service heavy: installation projects create the initial relationship, but repeat revenue tends to come from scheduled servicing, compliance-led maintenance, call-outs and replacement of ageing equipment. Buyers are usually local or regional rather than national, and engagements are practical rather than platform-led, with engineer availability, response times and documentation often carrying more weight than brand position.

Derby has 155 HVAC refrigeration companies actively trading, making this a compact local contractor market rather than a deep national supply base. Reported employment totals 250 people, so the footprint appears weighted towards small field teams and owner-managed service businesses. The count also points to a procurement environment where facilities managers can usually find local cover for routine maintenance, call-outs and equipment replacement, but the pool of larger contractors is narrow. For researchers, the useful distinction is less between heating and refrigeration and more between site-led maintenance capability, compliance discipline and responsiveness.
Refrigeration and air-conditioning work is shaped by safety, environmental and maintenance obligations around pressure systems, refrigerants, energy use and occupied buildings. Buyers tend to ask for proof that engineers can work safely on operational sites, manage leak checks and keep service histories current, particularly where chilled storage or process cooling affects continuity. Market structure follows from that: contractors compete on response coverage, engineer scheduling and traceable maintenance records. Public-sector and industrial buyers can lengthen sales cycles, while emergency repair work keeps relationships local and operationally led.
Derby's contractor base appears likely to stay fragmented, with many firms remaining close to owner-managed service operations and relatively few pushing into multi-site managed maintenance. Demand tends to track the condition of local commercial property, industrial plant and cold-chain assets, so replacement cycles may matter as much as new installation work. Energy-efficiency upgrades and refrigerant-management requirements should favour contractors that can document work cleanly and schedule engineers reliably. Consolidation is plausible where buyers want broader cover, but the more common pattern is likely to be incremental specialisation by site type and service response model.

Key facts
About 1% of the trading cohort reports turnover above £5M (1 of 155 firms) — the rest sits below that revenue band.
24% of the cohort was incorporated since 2022 (38 firms), so a sizeable share is in its first few filing cycles.
Derby-area HVAC and refrigeration providers tend to sell installation, planned maintenance and emergency call-out work rather than equipment-only supply.
Temperature-controlled premises create non-discretionary work: outages affect comfort, product storage and continuity of service.
Buyer procurement is often local and service-led, with response times, engineer availability and maintenance coverage shaping supplier choice.
Cold-chain work links contractors to premises where refrigeration failure can interrupt storage, distribution or service continuity.

How Derby HVAC Refrigeration companies work and how to sell to them
What they do
HVAC refrigeration contractors in Derby usually earn from a mix of installation projects, equipment replacement, planned maintenance and reactive repair. Revenue often combines fixed-price quotations for new plant, labour-and-parts billing for call-outs, and recurring service agreements covering inspections, leak checks, filter changes and record keeping. Margins tend to sit in the coordination of engineers, parts, subcontractors and site access rather than in a purely digital product. The commercial offer is a service bundle: skilled labour, physical equipment, compliance paperwork and availability when a site has lost heating, cooling or cold storage capacity.
Who they sell to
Typical customers include commercial landlords, manufacturers, warehousing operators, cold-chain users, leisure sites, schools and local public-sector estates. The day-to-day buyer is often a facilities manager, estates lead, plant engineer or operations manager, with finance and procurement joining when work becomes planned, multi-site or tendered. Emergency repairs can be bought quickly by phone or referral, while maintenance contracts and replacement projects usually involve site surveys, written quotations and supplier checks. Most sales are direct and relationship-led, although larger public-sector or industrial accounts may require formal tendering, insurance evidence and method statements before an order is placed.
What they buy
Most HVAC refrigeration firms tend to spend on tools that keep field work moving: job scheduling, mobile engineer reporting, quote and invoice handling, stock control, fleet administration and customer service systems. Compliance-led work also creates demand for document management, health and safety support, training, certification tracking and audit-ready service histories. Finance, payroll, insurance, legal support and accountancy remain routine needs for owner-managed contractors. As firms add engineers, recruitment, apprenticeship support, local search marketing and call-handling services become more relevant. Suppliers with logistics, parts availability or workflow visibility angles often have a clearer entry point than those selling generic office software.
Why and how to sell to them
Buying intent often appears when a contractor wins a larger maintenance account, hires engineers, adds public-sector work, takes on more emergency cover or moves beyond owner-managed scheduling. Pain tends to be operational: missed appointments, van downtime, poor first-time fix rates, slow quotation follow-up, unbilled parts and service records scattered across paper, email and spreadsheets. Energy-efficiency projects and refrigerant-management requirements can also push buyers to review systems and suppliers. Outbound messages tend to work better when they refer to engineer utilisation, audit trails, response times, cash collection or tender readiness, rather than broad claims about growth. Proof from comparable field-service businesses is usually more useful than general construction-sector language.
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.
