Accreditations and guarantees

In plain English

What each one actually means

Accreditation names tell you very little on their own, so here is what each of ours involves and why it matters to a homeowner or a landlord.

CHAS Elite accreditation logo

CHAS Elite accredited

CHAS assesses contractors on health and safety, insurance, training and compliance. Elite is its higher tier, which also covers areas such as environmental and quality management. It is the accreditation local authorities, agents and commercial clients most often ask us for.

Triton Approved Contractor logo

Triton Approved Installer

Triton manufactures damp proofing and waterproofing systems. Approved Installer status means we are trained and audited to install their systems as specified, which is also what allows the manufacturer backed guarantee to be issued on completion.

Standards

The rule books we work to

Where a British Standard covers the work, we follow it. That is what allows a surveyor, lender or solicitor to accept the work without argument.

BS 6576
Installing chemical damp proof courses in walls
BS 8102
Protecting structures below ground level from water
BS 1243
Metal ties used to tie the two leaves of a cavity wall together

Your guarantee

What the 30 year guarantee covers

Issued on completion once the work is signed off and paid. It is registered in the property owner's name and can be passed to a buyer. Full terms are supplied with the certificate by MP Preservation & Building Ltd.

  • The installed damp proofing or waterproofing system, for 30 years from completion.
  • Registered in the property owner's name, so there is no dispute over who holds it.
  • Transferable to the next owner when the property is sold.
  • Documented scope of works, so what is covered is not open to interpretation.
