About Maintain 12

Our Story

London's best properties deserve more than a passing repair job. They demand precision, reliability, and a team that understands the value of time, discretion, and workmanship that's actually finished properly.

Maintain 12 was created to take the stress and guesswork out of property care. No chasing contractors. No vague promises. No disruption to your life or your business. We started as a maintenance company — and we still are one at heart, but our clients kept asking for the same thing: Could you also design it, and could you also manage the whole project?' So we built the teams to say yes.

How We Work

• Trusted, Vetted Professionals - tradespeople and designers who take pride in their craft, not just their invoice.
• Upfront Pricing and Clear Communication - from the first phone call to the final invoice.
• One Standard, Every Discipline - the same luxury-home attention to detail across maintenance, design and project delivery.
• Rapid Response - when something urgent comes up, we don't make you wait for a callback.
• A Spotless Finish - every visit, every project, every time.

What We Believe

Property care shouldn't be three separate headaches. It should be one relationship you trust completely, whether that's a one-off callout, a full room redesign, or a multi-month refurbishment we manage from start to finish.

Maintain 12: where exceptional service is the standard, not the upgrade.

Who We Work With

We proudly support some of South West London's most prestigious homes, as well as commercial landlords, estate agents and property managers who need a partner they don't have to check up on. Fast, reliable and discreet, handled by experts who get it right the first time.
