Overview

Everest Home Improvement was a British home-improvement company best known for manufacturing, selling, and installing replacement windows and doors. Founded by Lewis Golden in 1964, it became one of the early large-scale participants in the United Kingdom's double-glazing market. The business operated in a highly fragmented sector containing thousands of companies and developed a national sales and installation presence, supported by manufacturing sites in Sittingbourne, Kent, and Treherbert, Wales, as well as product-development, design, installation, and sales functions. The Everest name became particularly associated with domestic energy efficiency and draught reduction. Its best-known advertising line, "Fit the best. Everest," was introduced in the 1980s and reinforced by a television commercial filmed at the Tan Hill Inn in North Yorkshire. The advertisement featured television personality Ted Moult demonstrating the insulation qualities of double glazing by dropping a feather beside a window while severe weather was shown outside. A later version featuring Craig Doyle appeared in 2008. The campaign helped make Everest one of the most recognizable names in the British replacement-window market, although the brand also faced regulatory scrutiny over advertising claims. By 2009, Everest was described as the United Kingdom's second-largest company in its market by sales and turnover, with reported sales of £165 million and an estimated 2.5% market share. Its market share was later reported as approximately 3%. Everest's sales organization included more than 1,000 salespeople operating as franchisees or self-employed representatives rather than direct employees. In 2012, private-equity firm Better Capital acquired the company for £25 million. The business subsequently reported more than 2,000 staff during 2013 and operating profits exceeding £5.1 million for the 2012–2013 period. The company expanded beyond conventional double glazing. In 2014, Everest Windows introduced triple glazing to the volume market, alongside its established ranges of windows, doors, and exterior structures. The company also marketed solar-related products, including solar panels, although some advertising claims about hot-water generation and cost savings were later prohibited or required to be amended by the Advertising Standards Authority. Everest Limited entered administration on 6 June 2020. A replacement company, Everest 2020 Limited, was formed during the same month and acquired operations and the order book. The restructuring generated consumer criticism because the successor company did not honor warranties issued to some customers of the former business while continuing to use similar branding and references to the Everest heritage. The successor entity later operated as Everest 2000 Limited. On 24 April 2024, Everest 2000 Limited entered administration, with approximately 350 jobs reported to be at risk. The sequence of administrations left the original Everest operating company and its later successor entities unable to continue as the same trading business, although the Everest name remained associated with the British home-improvement sector.

History

Everest Home Improvement was founded in 1964 by Lewis Golden in the United Kingdom. It became one of the early companies operating in the country's developing double-glazing industry. The sector later became highly fragmented, with more than 3,000 businesses competing for residential replacement-window and home-improvement work. Everest nevertheless expanded into a substantial national operator and was described by 2009 as the second-largest company in the British market by sales and turnover. Reported 2009 sales were £165 million, representing approximately 2.5% of the market; later descriptions placed its share at about 3%. The company developed a vertically organized operating model. It maintained manufacturing facilities in Sittingbourne, Kent, and Treherbert, Wales, and had its own product-development, design, installation, and sales functions. Its sales network included more than 1,000 representatives in 2009. These representatives operated as franchisees or self-employed salespeople rather than as conventional employees. By 2013, the company was described as employing more than 2,000 staff in its wider organization, and reported operating profits for 2012–2013 exceeded £5.1 million. Everest's public identity was built heavily through advertising. Its slogan, "Fit the best. Everest," was created by advertising executive Rod Allen and became closely linked with an influential television campaign first used in the 1980s. The commercial was filmed at the Tan Hill Inn, described in the campaign as Britain's highest pub, and featured Ted Moult using a feather to illustrate the draught-proofing effect of double-glazed windows while a gale raged outside. A revised version featuring Craig Doyle was produced in 2008. The filming location later attracted controversy after local planning officials identified authorization issues concerning improvement work carried out at the commercial premises. In March 2012, private-equity firm Better Capital acquired Everest for £25 million. Under the ownership period that followed, the company continued to develop its product range and market presence. In 2013 it won an Interactive Media Award recognizing aspects of its website and digital presentation, including content, design, functionality, compliance, and usability. In 2014, Everest Windows introduced triple glazing to the volume market, extending the brand beyond its established double-glazed window offering. The business also sold doors, exterior structures, and solar-related products. The solar business brought regulatory difficulties. In 2008, the Advertising Standards Authority prohibited a television advertisement because it could mislead viewers about the quantity of hot water that a solar panel could generate. Everest subsequently amended the advertisement. In 2011, the regulator banned another Everest solar-panel advertisement over claims about possible savings. Consumer organization Which? also reported in 2010 on sales practices used across the door-to-door double-glazing industry, describing concerns about aggressive or unsuitable tactics among companies it investigated; the report formed part of the broader consumer context in which Everest operated. The original Everest Limited entered administration on 6 June 2020. Better Capital then formed Everest 2020 Limited, which acquired the operating business and order book. The restructuring became contentious because the successor company did not honor warranties held by some customers of the former company while using the same or similar Everest branding and emphasizing the brand's long history. Consumer-program coverage, including BBC Watchdog, criticized the distinction between the old and new companies and the treatment of affected customers. The successor business later operated through Everest 2000 Limited. On 24 April 2024, Everest 2000 Limited entered administration and administrators from ReSolve Advisory Limited were appointed. Around 350 jobs were reported to be at risk. These events marked the collapse of the successor operation and left Everest Home Improvement as a historically important but no longer continuously operating British home-improvement business.
