All In Building Services is a family-run plumbing & building services practice in London. We run jobs from the first fix through to the last compliance sign-off — with the same engineers on-site from start to finish.
Our work sits across three areas: residential installations and repairs, commercial plant-room and water-hygiene services, and the mechanical building-services maintenance that keeps buildings running. No sub-contracted quality. No vague invoices.
Thames Water Approved, CIPHE & WaterSafe registered — with G3 Unvented, HIU and NVQ qualifications behind every engineer.
Leak detection, fault-finding and pressure diagnostics that get to the root cause — we don’t repeat-visit what we can properly solve on day one.
Flat hourly rates, out-of-hours clearly disclosed. No call-out surprises, no mystery line-items on the invoice.
Legionella risk assessments, Dead Leg Remedials, tank disinfection, PPM contracts — engineered to tick the boxes building managers can’t afford to miss.
From single-radiator swaps in Dulwich townhouses to Legionella-compliant cold-water systems in Streatham commercial blocks — we run both sides of the trade under one roof.
Our engineers work to a simple rule: leave a property tidier than we found it, and leave the system working better than it did before. That’s what gets us the repeat calls, the landlord retainers, and the block-management contracts that make up most of our week.
Behind every booking is over twenty years of London pipework — the tenement conversions, the lead-pipe replacements, the plant-rooms no-one else wants to open up. We’ve seen it, we’ve fixed it, and we’re still learning.
One hourly rate. No call-out fees. No hidden extras. Out-of-hours and weekend work is clearly priced up-front.
Based in South London, covering the whole of London and everywhere inside the M25. If you’re on our side of the ring-road, we’ll usually be on-site within the day.
