Our Expertise
Our engineering maintenance desk briefs by deployment model first, discipline second. A mobile engineer on a multi-site FM portfolio works a different day to a shift engineer in a Tier IV data centre, and both look nothing like a static engineer on a single-site NHS trust. We recruit the way the market actually hires.
We place mobile, static and shift engineers, specialist trades (HVAC, BMS, water hygiene, F-gas, HV-authorised electrical), engineering supervisors and contract managers, plus the technical compliance and asset data people operating CAFM platforms behind the scenes. We are SFG20 literate throughout, fluent on BS 7671 18th Edition Amendment 2, the UK retained F-gas regime, ACoP L8 water hygiene and HTM healthcare standards.
Why It Matters
UK engineering maintenance hiring is now gated on deployment model, competence evidence and compliance fluency in ways a generalist desk simply cannot sift for. A specialist desk is how you keep a maintenance regime compliant and fully staffed.
“Moston understood the difference between a conventional FM shift engineer and a Tier IV data centre engineer. HV authorisation and live critical environment delivery were verified, not assumed.”

Average time to shortlist
Data centres, life sciences, hospitals and pharmaceutical manufacturing have redrawn the upper end of the UK engineering maintenance salary curve. Tier III and Tier IV shift engineering roles now clear pay bands general FM contractors cannot match for equivalent technical scope. The knock-on effect has tightened the mid-market engineer supply across every major FM portfolio.
Find Maintenance Engineers →Almost every mobile and static brief now asks for multi-skilled competence. The reality is that engineers who are genuinely air-con fluent AND 18th Edition authorised AND ACoP L8 water-competent are thin on the ground. CVs list the competence; site-level track record often does not. We verify depth, not just breadth, before shortlisting.
Our Approach
Six deployment models, SFG20 and CAFM-literate assessment, and full coverage from FM portfolio to Tier IV data centre. The baseline an engineering maintenance recruitment agency has to meet.
We are not generalists who happen to cover maintenance. Every consultant on this desk works engineering maintenance and can interrogate the standards, deployment models and competence regimes that define the brief:
Deployment models
mobile, static and shift work are three different candidate pools. We brief each one against its own pay bands, rota patterns and site realities.
Standards fluency
SFG20 maintenance task library, HTM healthcare suite, ACoP L8 water hygiene, F-gas retained regulation, BS 7671 18th Edition Amendment 2, CompEx for hazardous area.
CAFM platforms
Planon, IBM Maximo, Concept Evolution, Archibus, FSI Concept, Elogbooks. We test platform-specific skills rather than taking the word CAFM at face value.
Critical environment context
Tier III and Tier IV data centre, life sciences, pharma manufacturing, NHS HTM-governed estates, broadcast and trading-floor 24/7 environments.
Fifteen years in the market and the relationships are how this works. Active conversations with IET and IMechE-aligned engineers, HV-authorised shift teams, BMS specialists and the people they trust:
Mobile and static engineers
mechanical, electrical and multi-skilled engineers on FM contractor portfolios, NHS trust estates, higher education campuses and corporate HQs.
Shift engineers
HV-authorised critical environment engineers in data centres, life sciences, pharmaceutical and broadcast, often placed before they are actively looking.
Specialist trade
HVAC engineers with F-gas Category I-IV, BMS engineers on Trend, Tridium, Siemens and Cylon, water hygiene engineers and commissioning engineers.
Engineering supervision and leadership
Engineering Supervisors, Technical Managers, Account Managers, Contract Managers and Heads of Engineering on FM portfolios and in-house teams.
Most engineering maintenance shortlists land in 72 hours. That is because the work happens before the brief rather than during it:
Brief scoping by deployment model
we lock down shift pattern, site model, authorisation level and SFG20 scope before we search, because a mobile brief and a Tier IV shift brief are not the same hire.
Proactive search
consultants work candidates directly. Most placements never appear on Indeed or generic engineering boards.
Competence verification
training currency, authorisation issue, live-site track record against named SFG20 modules. Listed competences alone do not clear the shortlist bar.
Curated shortlists
four engineers properly qualified for the deployment model, not twenty mis-matched CVs. The 94% twelve-month retention rate starts here.
Roles We Recruit
Mobile, static, shift, specialist trade, engineering supervision and contract management, and technical compliance and asset data. Six dedicated areas because deployment model drives hiring in UK engineering maintenance far more than base trade.

FAQs
Direct answers on SFG20, CAFM, F-gas, HV authorisation, ACoP L8, HTM and the competence regime we screen for.
SFG20 is the industry-standard maintenance specification library for UK building services, published by BESA (Building Engineering Services Association). It sets the recommended maintenance tasks, frequencies and statutory references for building services assets. SFG20 has become the default benchmark on FM engineering contracts and corporate estate maintenance regimes. An engineering maintenance CV is increasingly expected to demonstrate live work under specific SFG20 modules, not just name-recognition. We verify which modules candidates have operated under.
CAFM stands for Computer-Aided Facilities Management. It is the software platform category that manages maintenance schedules, reactive tickets, compliance records and asset data across buildings. The dominant UK platforms in engineering maintenance are Planon, Concept Evolution, Elogbooks, IBM Maximo, Archibus and FSI Concept. Fluency in one or more is now a screening criterion on most FM contractor mobile and static briefs, not an optional extra.
Three distinct deployment models. Mobile engineers work across multiple sites from a van, delivering PPM and reactive maintenance on FM contractor portfolios. Static (or site-based) engineers are dedicated to a single site, typically corporate estates, NHS trusts, higher education or major retail. Shift engineers work 24/7 rotas in critical environments such as data centres, life sciences, pharmaceutical manufacturing and broadcast. Pay bands, expected competences and career paths are different for each. We screen candidates to the deployment model they actually fit.
F-gas is the UK-retained regulation on fluorinated greenhouse gases, with Category I-IV certification required for engineers working on refrigeration and air conditioning systems containing F-gas refrigerants. HV authorisation (Authorised Person, Senior Authorised Person) is the safe-working regime for electrical engineers operating on high-voltage systems above 1,000V, usually site-specific. The 18th Edition BS 7671 Amendment 2 is the current UK Requirements for Electrical Installations, with electricians expected to hold a current 18th Edition qualification. We verify issue and currency on every relevant brief.
ACoP L8 is the Approved Code of Practice for the control of legionella bacteria in water systems, supported by HSG274 guidance. It sets the legal regime for water hygiene on every UK building with a wet system. Water hygiene engineers, legionella risk assessors and any maintenance engineer with water-system scope are expected to be trained to L8 and HSG274 standards. Specialist water hygiene engineers often combine L8 competence with City & Guilds building services engineering qualifications.
HTM stands for Health Technical Memoranda, the technical and operational guidance documents governing NHS estate building services. HTM 03-01 covers ventilation, HTM 04-01 covers hot and cold water safety, HTM 06 covers electrical services, HTM 2015 covers medical gas pipeline systems. NHS trust engineering and FM contractors delivering on NHS estates brief directly to HTM standards, and our desk screens for HTM-aligned experience on healthcare maintenance briefs.
Broad 2026 ranges. Mobile Maintenance Engineer 32 to 48 thousand (plus van, on-call). Static Engineer 32 to 50. Shift Engineer 42 to 65 (critical environments at the upper end, data centres and life sciences commonly 55 to 70 plus shift allowance). Multi-skilled Engineer with HV authorisation 45 to 62. BMS Engineer 40 to 60. Water Hygiene Engineer 32 to 48. Engineering Supervisor 45 to 62. Contract Manager 55 to 80. Head of Engineering 75 to 110. London, M4 corridor and data centre premiums apply. Day rates for contract roles run 200 to 450.
Yes, both. We work across the major UK FM contractors (Mitie, Equans, CBRE, JLL, Sodexo, ISS, Amey and Apleona among them) on general-estate mobile and static hiring, and across the critical environment operator market (hyperscale cloud and colocation) on Tier III and Tier IV data centre shift engineering. Life sciences, pharma manufacturing, hospitals and broadcast critical environments are also briefed separately where technical context differs.
Yes. A meaningful share of our volume sits above the tool-holding engineer layer. Engineering Supervisors, Technical Managers, Account Managers, Contract Managers and Heads of Engineering are all briefed regularly. These roles require different assessment than shop-floor engineering: commercial fluency, P&L exposure, SLA management, CAFM reporting and people management all come into scope.
Yes, across all three. Permanent placements are the majority volume for engineering maintenance. Contract cover is common for project peaks, PPM mobilisations, shift-team stand-up and specialist trades such as BMS commissioning. Interim management placements are used on contract mobilisations, account turnarounds and standing up new operational teams after FM contract wins.
Facilities management (FM) is the broader sector. FM hiring includes soft services (cleaning, catering, security, front-of-house), hard services (the engineering maintenance discipline covered here) and the management, operations and workplace layer above both. Our FM page covers the full sector. This engineering maintenance page focuses specifically on the hands-on hard-services engineering population plus the engineering supervision and technical compliance surrounding it. The two pages cross-link and cover distinct hiring pools.
Yes. BMS engineers (Trend, Tridium, Siemens, Cylon platforms), commissioning engineers (mechanical and electrical), water hygiene engineers (ACoP L8 and HSG274), F-gas refrigeration engineers (Category I-IV), HV-authorised electrical engineers and fire systems engineers all sit within our specialist trade remit. Specialist trade hiring is a distinct pool and typically briefs directly to the operator or specialist subcontractor rather than through the generalist FM channel.
