Four commitments, and where each one comes from.

The whole renovation is carried by one team with its own joiners, plumbers, electricians and craftsmen. You get one number to ring and one programme to follow, and no trade gets to blame the one before it.

Cheshire Renovations' own description of the work: "We specialise in full or part renovations and extensions, we cover everything from the foundations to the plastering."

Scope is quoted in writing and broken down. Anything found mid-job that changes it is re-quoted in writing and agreed before it is carried out — so the final invoice never contains a surprise.

The company's published terms and conditions set out detailed written quotations and revised quotations for additional work.

The conversation starts with what the house could be and what you actually want, then works to what that costs — with an itemised quote you can take things out of, rather than a single number to accept or refuse.

Their own words: "we work with you to create innovative ideas and achieve the result you want at a price you can afford."

A renovation happens inside somebody's home. Protecting the parts not in the works, keeping the site containable, and making practical arrangements so a family can carry on is part of the job, not a favour.

"The temporary kitchen they set up for us was a lifesaver during the build… Care and attention was give throughout the job" — Jason Singh, Google.
