Commercial Services South London | 24/7 Compliance & Maintenance

Trusted Commercial Solutions | Out-of-Hours Support | Professional Safety & Maintenance

South London’s commercial landscape is more varied than its central counterpart — alongside the offices and retail units you’d expect, the area around Croydon and Bromley has a real concentration of light-industrial units and warehouses, each with their own heating and gas compliance needs that a standard office doesn’t have. OSO Group Engineers provides commercial gas, electrical, and heating services across South London, with engineers equally comfortable servicing a retail unit on a high street or a heating system in a distribution warehouse.

FREQUENTLY ASKED QUESTIONS

Do you service heating systems in warehouses and industrial units?

Yes, we work with light-industrial and warehouse properties across South London, which often run larger or different heating systems compared to standard offices and retail units.

What compliance certificates do South London landlords typically need?

Most commercial landlords need a current CP12 Gas Safety Certificate and an up-to-date EICR, alongside working smoke and carbon monoxide alarms — we can advise on what applies to your specific property.

Can you handle multiple sites for a business with several South London locations?

Yes, we work with businesses managing more than one commercial property and can coordinate servicing and compliance across multiple sites.

Do you provide emergency call-outs for retail units during trading hours?

Yes, we treat commercial emergencies affecting trading businesses as a priority, and where possible we work around your operating hours for non-urgent work.

How often should a warehouse heating system be serviced?

This depends on the system and usage, but annual servicing is the minimum recommendation — high-use industrial systems often benefit from more frequent checks.

Do you offer ongoing maintenance contracts for South London businesses?

Yes, we offer scheduled maintenance plans so commercial properties can stay ahead of compliance deadlines rather than dealing with issues reactively.
