He Built a £4.2M HVAC Business in 28 Years. Then He Let It Go.

Dave Whitfield spent 28 years building Whitfield Mechanical Services from a single Transit van into a £4.2 million HVAC operation across the East Midlands. In March 2024, he sold to a regional roll-up backed by a mid-market private equity firm. This is what happened next.

The Moment It Started

It was not a spreadsheet that made Dave think about selling. It was a Tuesday evening in November 2023, sitting in his van outside a job in Loughborough, when his wife Sarah rang.

"She asked me what would happen to us if I dropped dead tomorrow," Dave says, laughing now but not laughing then. "I did not have an answer. Thirty-one employees, a warehouse full of kit, contracts with three local councils, and no succession plan whatsoever. That was the moment."

Dave had built Whitfield Mechanical the way most trade business owners do: one job at a time, one hire at a time, one contract renewal at a time. By 2023, the company was turning over £4.2 million with an adjusted EBITDA of roughly £680,000. He had a strong management team, recurring maintenance contracts worth £1.8 million annually, and a reputation in the East Midlands that money cannot buy.

What he did not have was a plan for what came next.

Finding the Right Buyer

Dave's first instinct was to sell to his operations manager, Craig. "Craig's brilliant. He runs the day-to-day better than I ever did. But he did not have the capital, and I was not prepared to vendor-finance the whole thing and spend five years worrying about whether I would actually get paid."

A friend in the industry introduced Dave to a sell-side M&A advisor who specialised in essential service businesses. Within six weeks, the advisor had prepared a confidential information memorandum and approached twelve qualified buyers — a mix of private equity-backed platforms, independent operators, and one publicly listed facilities management group.

"I had no idea there were that many people actively looking to buy businesses like mine," Dave says. "I thought I would be begging someone to take it off my hands. It was the opposite."

The Numbers

Dave received four formal offers. The highest was 6.8x EBITDA from the PE-backed roll-up. The lowest was 4.5x from an independent operator who wanted Dave to stay on for three years. He chose the PE offer, which valued the business at approximately £4.6 million / $5.8 million on a cash-free, debt-free basis.

"The headline number was important, obviously. But what really mattered was the structure. Eighty per cent cash on completion, twenty per cent in a twelve-month earnout tied to revenue retention. My advisor negotiated a clause that said the buyer could not make material changes to the business during the earnout period without my written consent. That was worth its weight in gold."

The deal completed in March 2024, eleven weeks from heads of terms to completion. Dave describes the due diligence process as "intense but fair" and credits his bookkeeper, Janet, with having the financial records in order.

The First Monday Morning

Dave agreed to a six-month consultancy period post-completion, working three days a week to ensure a smooth handover.

"The first Monday after completion was surreal. I drove to the warehouse like I always do, parked in the same spot, walked in, and everything looked exactly the same. Same lads, same vans, same smell of coffee and diesel. But it was not mine anymore. That took a while to process."

He describes the first few weeks as a mix of relief and grief. "You spend nearly thirty years building something. It becomes your identity. When someone asks you what you do at a barbecue, you say 'I run an HVAC company.' Suddenly you do not run anything. You are just Dave."

What He Did With the Money

Dave is characteristically straightforward about the financial outcome. After tax, advisory fees, and the earnout (which he received in full in March 2025), he netted approximately £3.4 million / $4.3 million.

"First thing I did was pay off the mortgage. Should have done that years ago, but you know how it is — every spare penny goes back into the business. Second thing was a holiday. Sarah and I went to the Algarve for three weeks. I played golf every day and did not look at my phone once. Third thing was setting up a trust for the grandkids' education."

He invested the remainder with a wealth manager recommended by his accountant. "I am not a stocks and shares man. I wanted something boring and reliable. A bit like a well-maintained boiler, really."

Life After the Sale

When we spoke to Dave in February 2026, he was eleven months into full retirement. He plays golf three times a week at his local club in Nottingham, volunteers as a mentor with a local enterprise programme for young tradespeople, and has recently started restoring a 1972 MG Midget in his garage.

"People ask me if I miss it. Honestly? I miss the lads. I miss the banter on a Monday morning. I do not miss the 5am alarm, the cash flow stress, or the Sunday night dread of what is going to break on Monday. Sarah says I am a different person. More relaxed. More present. I think she is right."

His advice to other business owners considering a sale: "Do not wait until you are forced to sell. Do not wait until you are burnt out or ill or the market turns. Sell when the business is strong, when you have got options, and when you can negotiate from a position of strength. I wish I had done it two years earlier, to be honest."

Are You Thinking About Your Own Exit?

Dave's story is not unusual. Thousands of essential service business owners across the UK and US are sitting on valuable, sellable companies without a plan for what comes next. If you are one of them, the first step is understanding what your business is worth.
