A 19-year-old homeowner is warning others against seeking do-it-yourself repair advice online, particularly from platforms like TikTok and AI tools, after a failed attempt to fix her boiler resulted in an £1,800 repair bill.
Freya Constance Page Tavener, from London, discovered an unfamiliar fault code on her boiler when her hot water stopped working. Believing the repair would be straightforward, she turned to social media and AI for guidance. Numerous TikTok and YouTube videos claimed to offer quick fixes for the specific error code, and comments suggested similar DIY successes.
Tempted by the prospect of avoiding an engineer's call-out fee, which she estimated at around £250, Tavener decided to attempt the repair herself. She had previously used online tutorials for less complex DIY projects like decorating and assembling furniture. The online advice indicated that a stuck diverter valve was the likely issue. The diverter valve is responsible for directing hot water to either the radiators or the taps.
Following the instructions, Tavener removed the boiler casing and attempted to access and free the diverter valve. During this process, she inadvertently damaged the actuator's electrical connector and wiring. Upon switching the boiler back on, the damaged connection caused a fault with the printed circuit board, rendering the heating and hot water inoperable.
She then contacted a Gas Safe registered engineer, who replaced the diverter valve, actuator, printed circuit board, and wiring. The engineer informed her that the original diverter valve issue would have been a relatively simple and inexpensive repair. However, Tavener's DIY attempt had caused additional damage, necessitating the replacement of more components and significantly increasing the final cost.
Her total bill amounted to over £1,800, a sum she described as making her feel "sick." She emphasized that her attempt to save a few hundred pounds had resulted in a bill more than seven times that amount, along with days without heating or hot water.
Tavener stated that the experience has altered her perspective on online DIY tutorials. While acknowledging their usefulness for tasks like decorating or assembling flat-pack furniture, she cautioned that they can create a "false sense of confidence." She noted that online videos often oversimplify complex tasks, and that not every fix that works for one person will work for another, as boilers vary.
New research from boiler company Boxt indicates a trend among younger demographics to attempt DIY boiler repairs. The survey found that 31% of individuals aged 18 to 24 have tried to fix their own boilers or heating systems. Of this group, 25% turned to TikTok for advice, and 23% used AI tools like ChatGPT, Claude, and Gemini. This contrasts with only 8% of individuals over 55 who reported similar DIY repair attempts. The survey also revealed that 8% of all Britons have attempted to replace gas pipework themselves, a task experts strongly advise against.
According to UK law, all gas work must be performed by a qualified Gas Safe registered engineer. Adam Knight, lead gas safe engineer at Boxt, commented that while AI and social media can be educational, boiler repair should not be among the topics learned from these platforms. He warned that online tutorials can make complex tasks appear deceptively simple, and that a single mistake can escalate a minor repair into a costly one, potentially creating health and safety risks for households. Knight concluded, "Some jobs simply aren't DIY jobs."
