Mechanical and electrical install in progress on a Sentaur project
- Install & project works

Designed in-house. Installed by the team that maintains it.

From drawings to commissioned plant. Sentaur's project division delivers bespoke MEP install for new builds, refurbs, listed estates and luxury residentials. The same engineers who commission your plant on day one are the engineers who maintain it on year ten.

SECTION 01 / WHY SENTAUR

Most contractors leave when the install ends. We stay. That changes everything.

- Why usAn MEP install is a thirty-year decision. Plant gets specified once and lives with the building. The engineers who pick the kit, draw the system and bolt it in should still be on the phone when something trips in year fifteen. That isn't how the industry usually runs - it's how we run.
- Reason 01Our moat

One team, install through life.

Most contractors are install-only or facilities-only. We do both, with the same engineers and the same project manager. The team who commissions your plant on day one is on the call rota in year ten - same company, same accountability, no handover gap.

  • Same engineers in year ten
  • No FM handover defect window
  • Drawings live with the team
  • Cradle-to-grave project lead
- Reason 02

Designed and drawn in-house.

Mechanical, electrical, plumbing and controls all engineered under one roof. The drawings are signed off by the engineers who will commission the plant - and maintain it through the next thirty years.

  • M·E·P·C all in-house
  • No outsourced consultants
  • Designer is the installer
  • Single record, single team
- Reason 03

Independent. British. Since 1974.

Five decades of unbroken trading on London stock. No private equity, no holding company, no offshore parent. Decisions get made in the building, not three counties away. We optimise for year thirty, not next quarter.

  • Family-held since 1974
  • No private equity
  • No offshore parent
  • Year-thirty horizon
- Reason 04

Commercial, listed and luxury - all routine.

Commercial offices and retail are the daily book. Grade I and II listed estates, luxury residential and hotel flagships make up roughly the other half. Whether it is a Cat A office fit-out, a riser refurb on a live trading floor or plant rooms behind 18th-century plasterwork, statutory liaison and finish-grade work come built in - not subcontracted out when it gets hard.

  • Commercial offices & retail
  • Grade I & II listed
  • Luxury residential
  • Hotel flagships
SECTION 02 / DISCIPLINES

Four disciplines. One bespoke project team.

- Bespoke project worksNew fit-outs, refurbs and plant upgrades - designed and installed in-house, then carried through to long-term facilities maintenance by the same team. No subcontractor handovers. No re-learning the building. See selected install case studies for what that looks like in practice.

SECTION 03 / FROM DESIGN TO YEAR TEN

Four stages. Same team across all of them. Then ten more years on the rota.

- The install lifecycleMost contractors hand off after Stage 03. Our Stage 04 is where the install pays back the design choices we made in Stage 01. Same engineers, same project manager, same drawings - cradle to grave.
- Stage 01

Design.

Every discipline drawn under one roof - mechanical layouts, electrical schematics, plumbing risers, controls schedules. Compliance-led, costed by trade, signed off by the engineers who will be on site for the install. We start with the building, not a template.

  • All four disciplines in-house
  • Compliance-led (CIBSE · IET · gas)
  • Costed by trade, not lump sum
  • Designer is the installer
- Stage 02

Install.

Mechanical, electrical, plumbing or controls - whichever disciplines the job needs, delivered on site by direct-employed Sentaur engineers. Pre-fabbed off-site where possible to compress time on the live floor, with one project manager owning every trade through to handover.

  • M·E·P·Controls on site
  • Direct-employed engineers
  • Pre-fab · lifts · CDM · cut-overs
  • Single PM across every trade
- Stage 03

Commission.

Every trade tested, witnessed and certified to its own standard - F-Gas for refrigerant, NICEIC for electrical, Gas Safe for gas, BCIA for controls. O&M pack, as-built drawings, asset register populated, FM team trained on the plant. Nothing leaves site without the certificate.

  • Witnessed testing on every trade
  • F-Gas · NICEIC · Gas Safe · BCIA
  • O&M, as-builts, asset register
  • FM team trained on the plant
- Stage 04Where we stay

Maintain. For the next ten years.

PPM tailored to the SLA, statutory compliance lodged, 24/7 reactive helpdesk. The engineers who commissioned the plant are the engineers maintaining it - same company, same accountability, year on year. This is where the install pays back.

  • PPM tailored to the SLA
  • Statutory compliance lodged
  • 24/7 reactive cover
  • Same engineers, year on year
Section 04 / The Sentaur principles

The Sentaur principles. What we stand for.

- Non-negotiableSix commitments that hold across every install we deliver - and across the decade of maintenance that follows. Not aspirational. Not bullet points on a tender. The way we actually run jobs from drawings to year ten.
01Continuity

The same engineers, year on year.

On every install we deliver, the same engineers carry through to PPM. The team that designs your plant is the team that installs it, commissions it and answers the call when something trips in year ten. Continuity is the structural advantage we sell.

02Trust

On the keys.

Listed City estates, twenty-eight-floor luxury residentials, hotel back-of-house. We hold the keys because clients have trusted us with them - and across fifty-two years, we've never broken that trust.

03Independence

Still ours.

Independent since 1974. No private equity. No quarterly cost-cutting. Decisions are made in Kings Langley, not in a boardroom 6,000 miles away.

04Partnership

Long-term, by design.

Most of our clients have been with us for over a decade. Some for three decades. Whether we built the building or stepped into it, we stay - because the contracts that make sense are the ones that compound.

05Craft

Quietly competent.

Premium MEP isn't loud. We design, install and maintain to a standard the building takes for granted. The best work goes unnoticed - and the only time anyone notices it is when something stops working.

06Accountability

Audit-ready from day one.

Gas Safe, F-Gas, NICEIC, BCIA, SafeContractor - current, audited, verifiable. Every install hands over a full O&M pack, as-built drawings, witnessed commissioning records and trade-by-trade certification. Nothing leaves site without it.

SECTION 06 / BEFORE YOU BRIEF

Seen something close to your project? Then you'll have questions.

Most briefs that land in our inbox arrive after this scroll. The same six questions come with them - design, sectors, listed work, accreditations, handover, and the team that maintains afterwards. Below, the answers.

SECTION 07 / FAQ

Common questions. The same six come up before every install.

- Before you brief usWhatever the route in, developer, owner, FM team or consultant, these are the questions that land first on the design and install side. Straight answers, no marketing wash.
  • 01- Question

    How does a Sentaur install project start?

    We start with a brief, drawings or scope. Our in-house design team turns it into engineered MEP layouts, costed by discipline, with a single project manager owning delivery from kick-off to commissioning.

  • 02- Question

    Do you handle design and CAD in-house?

    Yes. Mechanical, electrical, plumbing and controls all designed in-house. No outsourced consultants, no handover gaps. The same engineers who draw the system commission it on site.

  • 03- Question

    What sectors do you install for?

    New builds and refurbs across luxury residentials, hotels, retail flagships, listed Grade I and II estates, lab and clean-room environments, plus commercial and critical-plant fit-outs.

  • 04- Question

    Will the team that installs also maintain it?

    If you take a PPM contract, yes. The engineers who commission your plant on day one are the engineers who maintain it on year ten. No handover, no re-learning the building.

  • 05- Question

    Can you work on listed buildings?

    Yes. Listed Grade I and II are part of our regular portfolio. We handle statutory liaison, conservation officer queries and the discreet routing that listed-building work demands.

  • 06- Question

    What accreditations cover your install work?

    Gas Safe, F-Gas via REFCOM, NICEIC, BAFE for fire systems, plus ISO 9001, 14001 and 45001 for quality, environmental and health and safety management. All current, audited annually.
