Our maintenance service offers:

30 mobile engineers in and around London, equipped with mobile phones, who respond to urgent call-outs.

All mobile units carry equipment and materials which can repair most problems. Where other materials are needed, these are sourced quickly from key suppliers throughout London and the Home Counties
All minor repairs can be carried out immediately – for example, the replacement of a fluorescent lamp or a socket outlet
Access to a network of mobile engineers nationwide

Planned maintenance is the drawing up of a schedule to anticipate and greatly reduce the chance of any disruption to normal activities. This is designed to reduce overall maintenance costs as the likelihood of breakdowns and emergency call outs are less likely to occur. Also, maintenance is carried out at a time of least inconvenience to the customer’s site.

However when an emergency call out is required – responsive maintenance – Munns’ customers benefit from a fast, responsive and effective service.


All our mobile engineers carry identification and wear Munns logo shirts, so that they are instantly identifiable. This is important when visiting sites utilised by the public or occupied by vulnerable groups of people, for example, railway stations, old peoples’ homes, schools and hospitals.
