LHH Scotland and Dorset-based Lyme Bay Holidays will operate as sister agencies following the Sykes deal, adding a further 450 properties to its portfolio.
It means Sykes now offers more than 22,000 cottages across the UK, Ireland and New Zealand, up from around 5,000 five years ago.
The acquisitions will, in particular, increase Sykes’ options in Scotland, Dorset and Devon.
Balblair-based LHH Scotland manages more than 125 holiday homes across Scotland, with around half of these in the Outer Hebrides.
Lyme Bay Holidays, meanwhile, was founded more than 40 years ago and has been run by the Matthews family for more than 20 years.
