Construction Site Services — Temporary Power, Water, Welfare & Heating

Delays during site setup can derail your entire project. Whether it’s power, lighting, plumbing, or welfare facilities — if just one element slips, everything stalls.

That’s why principal contractors trust ETS to deliver complete construction site services, fast and without fuss.

From temporary site power and lighting to water, heating, and welfare units, we get your site ready for work — safely, efficiently, and in full compliance with CDM regulations.

One contractor. Everything handled. No unnecessary delays.

Trusted on high-security and public sector projects. Our teams hold the security clearances and accreditations required to work on Ministry of Defence sites and live HM Prison estate projects — including the documentation, vetting, and CDM compliance these environments demand. If your project has elevated security or compliance requirements, you’re talking to the right contractor.

Everything Your Site Needs — Installed, Managed, and Off Your Plate

Getting a site up and running is one of the most demanding phases of any project. Power, lighting, water, heating, welfare — it all needs to be in place, fast, safe, and fully compliant. That’s where we come in.

We make it easy for you to focus on the build — not the background logistics.

At ETS, we handle the complete setup of your construction site infrastructure, ensuring your team has everything they need to work safely and efficiently from day one. From temporary installations to ongoing support throughout the project, we’re there when you need us — and gone when you don’t.

Very few companies in the UK offer this full-service approach. Even fewer deliver it with the trust, speed, and clarity we’re known for.

The Contractor You Call Before You've Called the Other Contractor

When you’re under pressure to get a site live, you often can’t wait for the full M&E tender to wrap up before work has to start. Welfare units need power. The first trades need lighting. The principal contractor needs the site CDM-compliant from day one — not whenever the procurement process finishes.

That’s where we come in.

We’re often the first contractor on site, mobilised before the main mechanical and electrical provider has even been appointed. We get your temporary power, water, lighting, welfare, and heating live — so your programme starts on time, your enabling works proceed, and your team isn’t sitting around waiting for someone else to be picked.

When the permanent M&E contractor is finally appointed, we hand over cleanly. No conflict, no overlap, no scope confusion. Just a site that’s already operational and ready for them to plug into.

We also handle the things other contractors won’t touch:

Refurbishment of existing site infrastructure — old welfare units, tired distribution boards, ageing power runs, drainage that needs reworking. If the existing site setup isn’t fit for purpose, we’ll fix it rather than make you start from scratch.
Urgent, short-notice work — broken power, failed heating in winter, a welfare unit that’s stopped working. If your site has a problem today, we can usually be on site within 24 hours.
Bridging the M&E gap — interim works that keep your programme moving while the main M&E contract is being decided, tendered, or mobilised.

You don’t need to wait for the right contractor to be appointed. Call us first, get the site live, and bring the others in when you’re ready.

Services Included in Construction Site Services

Plumbing Services

On a live construction site, plumbing isn’t optional — it’s essential. Whether it’s for welfare facilities, site cabins or water supply, your workforce needs plumbing that’s safe, compliant, and won’t break down halfway through the job. We install robust temporary plumbing systems that keep your site operating smoothly — with no dramas and no surprises. From toilets and sinks to hot water systems and waste management, we handle everything you need to keep your team working comfortably and compliantly. Need it sorted fast? We’re the team that gets it done right — first time.

Heating Services

Whether you're drying out new plaster, working through winter, or keeping welfare areas warm, the right heating setup makes all the difference to your site’s productivity and compliance. At ETS, we were one of the first UK contractors to bring innovative, stage-specific heating techniques to construction sites — helping clients control temperature through every phase of the build. We design and install temporary heating systems that match your project's needs, ensuring the right conditions for your workforce, your materials, and your deadlines. From frost protection to fast-track drying — we’ve got you covered.

Electrical Services

When your site doesn’t have power, your project can’t move forward. That’s why we install temporary electrical systems that are ready to go — when and where you need them. From site cabins and lighting towers to full distribution boards and power runs across large plots, we make sure your team has access to safe, compliant power from day one. No delays. No guesswork. Whether it’s a short-term install or a full site setup that evolves as your build progresses, we’ll keep your site running — and your programme on track.

Unique Solutions

No two sites are the same — and your temporary services shouldn’t be either. We work closely with you from the start to design and deliver site infrastructure that fits your exact build schedule, layout, and operational needs. Whether you're phasing work across multiple plots or managing a high-pressure deadline, we’ll create a solution that keeps your team productive, compliant, and comfortable — without compromise. Our approach is hands-on, flexible, and built around one goal: keeping your site running without interruptions.

A Straightforward Setup That Gets You What You Need — Fast

Every site is different — but getting power, water, and welfare sorted shouldn’t be complicated.

We start with a site visit and consultation, so we understand exactly what you need and when. Then we get to work — installing your temporary electrics, plumbing, lighting, and heating with speed, safety, and zero disruption to your programme.

You won’t need to chase. You won’t need to coordinate multiple trades. You’ll just get the right setup, done right — so your team can get to work without delay.

How quickly can you get temporary power and welfare set up on a new site?

For most sites in our core area, we can carry out a site survey within 3–5 working days of your call, and have temporary power, welfare, and lighting installed within 1–2 weeks of order — depending on scope and any utility connections required.

For urgent or short-notice projects, we'll work with you to find the fastest realistic timeline. The earlier you involve us, the smoother the setup. Ideally we'd be talking to you at the planning stage, not the week before you break ground.

Do you handle CDM 2015 compliance for temporary site services?

Yes. Every installation we deliver is designed and installed to meet the Construction (Design and Management) Regulations 2015. That covers temporary electrical installations to BS 7671 (the IET Wiring Regulations), welfare facilities meeting Schedule 2 requirements, and safe water and drainage systems.

We provide all relevant test certificates, RAMS (risk assessments and method statements), and documentation your principal contractor needs to satisfy HSE requirements. You won't need to chase paperwork.

Can you work on live sites where other trades are already operating?

Absolutely — it's one of the things we do most. Whether you're phasing works across multiple plots, adding a new welfare block mid-project, or scaling power capacity as the build progresses, we're used to working around live trades without disrupting their programme.

Our team will coordinate directly with your site manager, attend pre-start meetings, and adapt installation timing to suit your wider build schedule.

What's typically included in a construction site setup package?

A standard setup usually includes some combination of: temporary power distribution (DBs, supplies to cabins and tools), site lighting and lighting towers, plumbing and water supply to welfare units, drainage and waste management, temporary heating for welfare areas and frost protection, and temporary fire and security alarm systems.

We tailor every package to your specific site — there's no one-size-fits-all. The best way to scope it is a 20-minute call followed by a site visit. Then we'll come back with a clear, itemised proposal so you know exactly what's included and what it costs.

Do you cover sites outside Bristol and the South West?

Our core delivery area is a 60-mile radius from Bristol and from Taunton — covering the South West, South Wales, the Midlands, Thames Valley, and the south coast. From Bath and Bristol across to Cardiff, Newport, and Swansea, down to Exeter, Plymouth, and Bournemouth, and up to Gloucester, Cheltenham, Worcester, and Birmingham.

For multi-site rollouts or projects further afield, we work UK-wide. We've delivered for national brands and main contractors across England and Wales — talk to us about your specific locations and we'll tell you honestly whether we're the right fit.

How does pricing work for construction site services?

Every site is different, so pricing is always tailored — but it's never opaque. After a site visit, we provide a clear, itemised proposal that breaks down each element (power, plumbing, welfare, heating, lighting) so you can see exactly what's included and how it adds up.

We're not the cheapest, and we don't try to be. What you get for the money is a single accountable contractor handling the whole setup, all the compliance documentation in one place, and a team that's been doing this since 1979.
