Mechanical Engineer | £40k–£46k + Van

London and Home Counties | Commercial Building Services

£40,000–£46,000 DOE + fully expensed van + fuel card + phone + iPad

If you''re an experienced Mechanical Engineer looking for a solid package, varied commercial work, and a company that takes a sensible approach to your working day, this could be worth a look.

I''m recruiting for an established building services business looking to add an experienced Mechanical Engineer to its mobile engineering team, covering London and the Home Counties.

This is a genuinely varied role covering planned maintenance, reactive breakdowns, fault finding, remedial works and mechanical installations across a commercial portfolio.

Why this role stands out

- £40,000–£46,000 basic salary, depending on experience
- 25 days'' holiday + bank holidays
- Fully expensed company van
- Fuel card
- Company phone
- Company iPad
- Nest pension
- 1-in-8 call-out rota
- £150 per week standby payment, paid in full via expenses
- Call-out attendance paid at 1.5x normal rate
- 4-hour minimum for call-out attendance, door-to-door

A sensible approach to working hours

The standard hours are 8am–5pm, but this isn''t a role where you''re expected to remain on site until 5pm simply because that''s what''s written on the contract.

Depending on your work area and workload, engineers will generally finish on site around 3pm–4pm and then travel home.

The business takes a practical approach to travel and understands that good engineers shouldn''t be kept on site unnecessarily.

What you''ll be doing

You''ll be responsible for maintaining, fault finding and repairing a range of commercial mechanical and building services systems.

Your workload will include:

- Planned preventative maintenance (PPM)
- Reactive maintenance and emergency breakdowns
- Mechanical fault finding and diagnosis
- HIU servicing, breakdowns and fault finding
- Commercial heating and hot water systems
- Boilers and associated controls
- Pumps and pressurisation units
- Expansion vessels
- Calorifiers
- Plate heat exchangers
- Water softeners
- LTHW and CHW systems
- AHUs and FCUs
- Supply and extract ventilation
- Motors, valves and actuators
- Mechanical plant and associated pipework
- New mechanical installations
- Commissioning and testing
- Remedial works identified during PPM visits

You''ll also complete job sheets and service reports, provide photographs and technical recommendations where required, and liaise professionally with clients, estate managers, site teams and specialist subcontractors.

What we''re looking for

You''ll need strong experience in commercial mechanical engineering / building services and be comfortable working independently across different sites.

Ideally, you''ll have experience with:

- Commercial heating and hot water systems
- Boilers, pumps and pressurisation systems
- Primary and secondary heating circuits
- LTHW / CHW systems
- Mechanical plant rooms
- AHUs, FCUs and ventilation
- Pumps, motors, valves and actuators
- PPM and reactive maintenance
- Mechanical fault finding
- Remedial works and installations

A good understanding of SFG20, manufacturer requirements, British Standards, RAMS, permit-to-work procedures and health and safety legislation is expected.

Experience with plant replacement, refurbishment, pricing remedial works or coordinating subcontractors would be advantageous.

The person

We''re looking for someone who can be trusted to get on with the job.

You''ll be:

- Technically strong and confident with fault finding
- Practical and solution-focused
- Comfortable making decisions on site
