About Certanly

Compliance made simple for London property

How we work

Three things we never compromise on

Built from the ground up to eliminate the frustration of landlord compliance.

Qualified for every trade

Gas Safe engineers for gas, NICEIC electricians for EICRs, NEBOSH assessors for fire. Each job goes to the right specialist.

Plain English, every time

You get a clear pass or a clear list of fixes with upfront prices. No jargon, no pressure to upgrade what doesn’t need it.

One fixed price

The price on the website is the price you pay. VAT included, no call-out charge, and 15% off combined visits.

Our engineers

Directly employed, never subcontracted

Every engineer is DBS-checked, fully insured and trained to explain results to landlords and tenants. They carry common parts in the van so minor defects can be rectified on the first visit.

DBS-checked, uniformed and fully insured
Tablet-equipped for same-day digital validation and report issuance
Customer-rated after every single visit to ensure 5-star service
