Leak detection and regassing in Greenford
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 a system in Greenford has needed gas before, the original leak was probably never fixed.
If an older system in your Greenford home uses R22, replacement is usually the route, because it can no longer be recharged. Greenford sits around 10 miles from central London, inside our London area. Postcode districts we cover here include UB6.
Prices in Greenford
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. On our London figures, the Standard option (leak in pipework or valve, full recharge) is about £495–£845.
