Camberford Law has introduced an online excess layer quotation facility for employers' liability (EL), public liability and product liability cover.
Cover is available for risks between £1m and £30m indemnity limit, said the wholesale broker.
The cover will be written through Lloyd's and the primary layer does not have to be placed through Camberford Law.
Camberford Law chairman and chief executive Richard Sheik said: "We found that some brokers were saying that they needed the excess layer cover immediately, as clients did not realise that additional cover was needed."
Sheik said the cover was available for a specific contract or for all an insured's insurance cover.
Camberford Law also said cover on its personal and commercial property schemes, and its rates for hotels, nightclubs, restaurants and leisure industry schemes, as well as its cleaning industry scheme, had been widened.
Premium rates have also been reduced, said the company.
