Leak detection services in Buckinghamshire

Water in an older building rarely shows itself where it starts. These are common starting points for an enquiry, before anyone decides what, if anything, needs opening up.

Water behind a wall
or beneath a floor

Pipework can run under boards, behind panelling or inside fitted joinery, and older alterations may have moved it. Say which finishes are original before anything is lifted.

A water bill that keeps
rising, with nothing showing

A meter that moves with everything turned off suggests water is escaping from the supply. Isolating sections of pipework helps narrow down where.

Heating pressure
that keeps dropping

Falling pressure shows the system needs investigating. It does not show where the water is going, particularly where pipes run inside thick walls or under solid floors.

Damp with
an uncertain source

Traditional walls can hold water from rain, the ground or condensation as well as from a leak. A meter reading on its own does not settle which.

How an investigation is arranged

Much of the planning happens before anyone arrives, because the building, its finishes and any permissions shape what can be done.

  1. Call with the building details

    Give the postcode, where water or damp is showing and what you know about the listing, plans and earlier investigations. The office discusses suitability before a visit is booked.

  2. Agree the scope and access

    Settle what will be investigated, which areas can be reached and who else needs to be involved. Request the booking terms before confirming.

  3. The investigation on site

    The engineer carries out the agreed investigation, using methods suited to the system and the fabric. Any further opening-up is discussed before it happens.

  4. Written findings

    The engineer prepares written findings to share with your advisers. A suspected location can still need further access before it is confirmed.

Leak detection methods and equipment

Methods are chosen for the system, the materials and the access available. Each has limits, so the findings are read together.

How methods are chosen
Thermal imaging
Shows surface temperature patterns that can help follow hot water and heating routes. It does not see inside a wall.
Moisture measurements
Compare readings across floors and walls. Salts and changes of material in older masonry can affect a meter, so readings are read alongside everything else.
Acoustic listening
Listens for sounds associated with water escaping from pressurised pipework. Site conditions affect how useful it is.
Tracer gas
Can assist on suitable systems by introducing gas to the pipework and detecting where it comes through.
Inspection cameras
Look into voids where suitable access already exists. Making a new opening is discussed first.

Consent and local information

Tracing a leak and changing historic fabric are separate decisions. Whether the work that follows needs consent is a question for the council.

Read the consent guidance
Who handles listed building consent
Buckinghamshire Council, for most of the county. It replaced the county council and the Aylesbury Vale, Chiltern, South Bucks and Wycombe district councils in April 2020, so older consents and plans may carry a former district name. In Milton Keynes, it is Milton Keynes City Council.
Work that needs consent in Buckinghamshire
The council’s guidance covers internal as well as external alterations, introducing new materials, and changing materials, giving a switch from metal to plastic pipes as an example. Read the council’s guidance.
If you are unsure
Buckinghamshire Council recommends its paid heritage advice service for finding out whether a piece of work needs consent. Read the council’s advice.
In Milton Keynes
Milton Keynes City Council says works affecting the character of a listed building need consent, inside as well as out, and that carrying them out without consent is a criminal offence. Read the city council’s page.
Checking whether a building is listed
Historic England’s National Heritage List for England is the official register of listed buildings. A place on Milton Keynes City Council’s MK New Town Heritage Register is locally significant, but that local list does not bring the extra consent controls of national listing.
Water supply
Thames Water, Anglian Water and Affinity Water each supply parts of the county. For a question about the supply pipe, go by the company named on the water bill.

Questions about Buckinghamshire

Is Milton Keynes included?

Yes. Milton Keynes is part of ceremonial Buckinghamshire, but it has its own city council, so consent questions there go to Milton Keynes City Council rather than Buckinghamshire Council.

Our address has a Slough or Maidenhead post town. Is that covered?

If the building is in Burnham, Farnham Common or Taplow, yes. Those Buckinghamshire places use a Slough or Maidenhead post town. Coverage is checked against the full postcode either way.

Could replacing old pipework need consent here?

It can. Buckinghamshire Council lists changing materials, for example from metal pipes to plastic pipes, among the work that needs listed building consent. Check a proposed repair with the council before it goes ahead. Read the council’s guidance.

Do you cover places that are not named here?

The places on this page are examples. Call with the full postcode and a short description of the building, and the office will check suitability and appointment availability.

How soon can an engineer attend?

That depends on the postcode, the building and the appointments available. Office hours are not a promise of engineer attendance, so ask about arrangements for your visit when you call.

Will floors or finishes have to be opened up?

Not every investigation needs it, but it cannot be ruled out in advance. Tell the office about original finishes and restricted areas, and settle any further access, and the permissions it may need, before work affecting the fabric goes ahead.

Who decides whether work needs listed building consent?

The local planning authority, usually through its conservation or heritage officers. A leak investigation does not replace that advice. Read the consent guidance.
