Leak detection and regassing across London

If an older system in your Westminster home uses R22, replacement is usually the route, because it can no longer be recharged. Flare joints are a frequent leak point on older split systems, so they are among the first things checked on a visit in Westminster. London's dense streets hold heat overnight, so top-floor flats and loft rooms often stay warm long after sunset.

Leak detection and regassing in London typically comes in at £325–£1,295 leak find, repair and recharge including VAT, based on London rates. London is one of the dearer parts of the UK for trades, which shows in the range. If parts or extra work turn out to be needed, the engineer explains and prices them before going ahead.

FAQ

Leak detection and regassing in London

Is there a call-out charge?

The price we agree before booking covers the visit and the agreed work. Anything extra is explained and priced before it is done.

All of London, including Islington, Westminster, Bexley and Barking. Each district has its own page below with local details.

How much does leak detection and regassing cost in London?

Our London guide range is £325–£1,295 leak find, repair and recharge, including VAT.

Can you just top up my air conditioning?

Not without finding and repairing the leak. Topping up a leaking system wastes money and releases greenhouse gases.

How long does a regas last?

Indefinitely, if the leak was properly repaired. Sealed systems should not lose refrigerant.
