Coming soon…super followers.

Subscription based access to unique insights and services as an alternative to traditional fee based commissions.

To increase efficiencies and reduce costs, during 2021, we are expanding our online facilities, offering competitive discounts to new and existing customers and where possible, simply make everyday tasks of seeking our QS services more straightforward!  ZOOM meetings are becoming part of the ‘new normal’.

From time to time, we shall post examples of costing familiar elements of work which clients undertake, to show the split between materials and labour.


Allied to this, with the continued population of QUANTUM COMMERCIAL, we aim to expand our services to provide a simple means of sourcing trades and services on one platform, to facilitate the connection of customers to suppliers, available 24/7 and 365 days per year, never sleeping !  We welcome all suppliers and service providers, increasing the choices available. Small, rural, parish based, niche suppliers and service providers are especially welcome as QUANTUM COMMERCIAL levels the playing field in terms of big firms against small firms.

No cold calling – direct email contacts are provided on listed products / services for ‘hot calling’ in return. Multiple, instantaneous inquiries can be broadcast with simplicity.

Welcome any constructive suggestions to expand and improve the services provided.
