Leak detection and regassing in Chiswick
If a system in Chiswick has needed gas before, the original leak was probably never fixed. In London, heat soaks into brick and concrete during the day and comes back out at night, which is when it is hardest to sleep.
If an older system in your Chiswick home uses R22, replacement is usually the route, because it can no longer be recharged. Chiswick sits around 6 miles from central London, inside our London area. Coverage includes W4.
Prices in Chiswick
In London, our guide range for leak detection and regassing is £325–£1,295 leak find, repair and recharge, including VAT. That is above the UK middle, mainly because labour and access cost more in London. The price depends mostly on how many indoor units there are and how easy the outdoor unit is to reach. For reference, the Standard option in Chiswick (leak in pipework or valve, full recharge) usually comes to about £495–£845.
