BADR relief when selling an electrical company

Are you an owner of an electrical or mechanical business contemplating a sale? Perhaps you have built a thriving enterprise specialising in industrial automation or commercial fit-outs, and now you are considering your next chapter. When planning such a significant transition, understanding the financial implications, especially tax relief, is paramount. Business Asset Disposal Relief, or BADR, which lowers the tax owners pay on the gain when they sell a business they work in, stands out as a key consideration for many UK business owners looking to reduce their Capital Gains Tax bill.

BADR, formerly known as Entrepreneurs' Relief, allows qualifying business owners to pay a reduced rate of Capital Gains Tax when they sell all or part of their business. Instead of the 24% main Capital Gains Tax rate a higher-rate taxpayer would otherwise pay, BADR has taxed qualifying gains at 18% since Apr 2026, up to a lifetime limit of £1 million. It was 10% until Apr 2025 and 14% in the 2025/26 tax year. For many electrical and mechanical business owners, this relief represents a substantial saving, significantly impacting the net proceeds from a sale.

What BADR Means for an Electrical Business Sale Now

The April 2026 date this article was written around has now passed. BADR rose in two steps and has been 18% since Apr 2026, so there is no longer a date to beat. What remains is a calmer calculation: at 18%, BADR is still well below the 24% main rate, and whether that gap narrows further is a question for future Budgets.

For an electrical or mechanical business owner, securing BADR on a sale in 2026 is worth up to £60,000 against the 24% main rate, on a full £1 million of qualifying gains. Because the rate is set by the date the sale contract is made, not the completion date, and future Budgets can change reliefs again, planning the tax side early is still worth doing.

Why Act Now: Market Conditions and Maximising Value

Beyond the tax implications, current market conditions present a compelling argument for considering a sale sooner rather than later. The UK's electrical and mechanical contracting market remains robust, driven by ongoing demand in infrastructure, commercial development, and the push towards sustainable technologies. This market creates an attractive environment for potential buyers, from larger national groups seeking to expand their regional footprint or service offerings, to a range of other acquirers. For an owner weighing up the timing, the market and the tax position are worth reviewing together, and a tax adviser can help you understand how BADR applies to your own sale.
