  • “Endless has worked closely with SIA Group across a number of its mid-market PE investments in recent months, supporting the refinance of over £75 million of total facilities. On each occasion SIA Group has proven itself to be a market leader in balancing detailed valuation analysis with commercial judgement, delivering high quality advice that can be relied upon by multiple stakeholders. The valuation and collateral due diligence teams across different asset categories are well organised, highly professional and joined up in their planning and reporting, delivering a one-stop solution, often to strict timetables. This, together with the strong relationships SIA Group has with funders and the reputation SIA Group commands in the market have proven invaluable in aligning asset based lenders and other funders to investor priorities.”

  • “When we set up Praetura Commercial Finance, SIA Group were our first port of call, both for outsourced asset valuations and regular ongoing audits. They have the depth of experience we need from a valuations and audit partner and back that up with a flexible and responsive service. What’s so great about SIA is that they have all worked in our industry and we have known one another for around 20 years. No other asset valuation and audit companies in the market can really say that. The market intelligence we receive from them is absolutely invaluable and they can advise us as to what the flags are, so that we can pick up the phone and have an intelligent dialogue with them. To be honest, I wouldn’t look to use anybody else.”

  • “SIA Group assisted the team throughout the restructuring process and provided independent professional advice on the assets at all times. They were integral throughout proceedings and their deep understanding and specialist knowledge of the business and its assets ensured a successful outcome from challenging circumstances. We were extremely impressed with their focus on customer care, experience and guidance".
    Ben Wiles
    Managing Director
  • “My working relationship with SIA Group spans 20 years and numerous projects. They know our industry and our issues intimately. They are at the top of their game in the asset based lending space. What consistently sets them apart is their responsiveness and commerciality. I know if I phoned them right now they would be on site tonight. They embody what ‘a safe pair of hands’ means".
