The Costley hotels group has staged a strong profit recovery after banking full insurance compensation for the fire that ravaged the historic Souter Johnnie's venue last year.

The 'House of Burns' at Kirkoswald is to reopen on October 1 after a rebuild and redevelopment, and the accounts just published show redress of £937,427 for fire destruction and loss of earnings, some £120,000 higher than the exceptional and write-off costs of the disaster in the 2012 financial year.

The year saw C & C, Ayrshire's biggest private employer, lift pre-tax profits from £50,293 to £326,189, on turnover down by 2.5% at £8.9 million, implying a rise in turnover excluding the closed outlet. The group's flagship hotels are the Lochgreen and Brig O'Doon, which recorded a "strong performance" helped by resilience in the "lucrative wedding market".

Operating profits improved from £379,903 to £609,930, and the positive cashflow helped the group to reduce debt from £9.3m to £9m. Employment however was affected by the closure, falling from 448 to 393.

The directors – headed by owners former Kilmarnock chairman Bill Costley and his wife Cath – said the Scottish hotel and leisure sector continued to suffer considerably from challenging trading conditions.

"The Costley group has the advantage of a strong reputation for quality and service and this, together with careful management controls and diversification, has meant that the group has remained relatively buoyant during difficult times".

The group's recent focus has been on developing the patisserie and chocolatier business in Prestwick, which now manufactures all the ice cream, cakes and chocolate sold in the group's outlets. The directors said the operation "highlights the culture of the group in demonstrating our philosophy of producing and manufacturing all that we serve within our hotels".

They said rebuilding at House of Burns, reopened after a £1m restoration in 2008, was well progressed. The new lay-out will integrate a tearoom and bakehouse in a rethatched restaurant block and have space for leasing.

Shareholders Mr and Mrs Costley each took a £50,000 dividend last year, and the highest paid director's remuneration rose from £84,031 to £87,164.
