The KT postcode area

The KT (Kingston upon Thames) postcode area is a group of 24 postcode districts across 19 post towns, covering the south west London boroughs of Kingston, Merton, Sutton and Richmond and the north east Surrey boroughs of Elmbridge, Epsom and Ewell, Mole Valley, Reigate and Banstead, Runnymede, Woking and Guildford. It is the area immediately south west of central London, and one that our team covers in depth, district by district.

Each district below lists the places it covers. Every link goes to that place’s own page (the same page you reach through the borough or council listings) so there is one page per place, not one per postcode.

What we do across the KT postcode area

The same methods on every job: measure, trace, prove, then fix. All services →

Leak detection

We locate concealed supply, heating and waste leaks under floors and behind finishes, and mark the exact spot.

Urgent leaks & burst pipes

If water is actively coming in, phone rather than fill in the form; live leaks go to the front of the queue.

Mould treatment & investigation

Mould is a symptom. We identify what is feeding it, treat the growth and specify the fix for the cause.

Damp & mould surveys

A survey that tells you the cause, not just that the wall is wet, and gives you a plan to put it right.

Book a damp, mould or leak investigation in the KT postcode area
