Leak detection and regassing in Westminster
Flare joints are a frequent leak point on older split systems, so they are among the first things checked on a visit in Westminster. 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 Westminster home uses R22, replacement is usually the route, because it can no longer be recharged. Westminster sits within our London area. Homes in SW1A, SW1E, SW1H, SW1P, SW1V and SW1W are all within our coverage.
Prices in Westminster
Our London guide price for leak detection and regassing is £325–£1,295 leak find, repair and recharge, VAT included. That is above the UK middle, mainly because labour and access cost more in London. The main variables are the number of indoor units, access to the outdoor unit and whether any parts are needed. On our London figures, the Standard option (leak in pipework or valve, full recharge) is about £495–£845.

Before booking, tell us the make and model and what the system is doing. We confirm the visit price, then the engineer arrives with the right equipment and, where possible, the right parts.
