Energy and utilities for construction companies and building sites
Construction firms juggle temporary supplies on site, permanent supplies at the office and depot, and waste rules that apply on every job. We arrange the supply contracts and keep the dates straight; the network operator builds the connection.
- Supply contracts and metering for temporary builders’ supplies
- Office, yard and depot energy quoted separately for electricity and gas
- Contractors’ insurance through FCA-authorised partner brokers
How Helios helps construction firms.
Sites open and close, but the paperwork does not stop. Helios keeps supplies, waste and cover for every site on one list.
Temporary supplies, step by step
We go through who does what for a temporary builders’ supply and look after the supply contract once the connection is in.
Site waste and duty of care
Skips and mixed site waste collected with the transfer notes your duty of care requires.
Every site on one list
Head office, yard and each live site with its own meters, end dates and documents in your portal.
Cover renewed on time
Contractors’ all risks and liability cover arranged by FCA-authorised partner brokers, with renewal dates tracked.
Temporary builders’ supplies: who does what
The network operator, or an independent connection provider, builds a temporary connection. National Grid describes a temporary connection as one used for less than 5 years, asks for a location plan and a site layout plan, and does not include the cost of disconnection in the connection offer.
UK Power Networks lists what the customer provides: a lockable, weatherproof enclosure for the service termination and the supplier’s metering, ducting to the required standard, and an RCD and earth electrode to BS 7671. The customer is also responsible for applying for disconnection when the supply is no longer needed.
How long a temporary supply can stay depends on the network operator and your connection offer, so check it rather than assume. Our part is the supply contract and metering with an electricity supplier, quoted against the site’s expected use.

Site waste: duty of care, transfer notes and Simpler Recycling
Under Simpler Recycling in England, construction sites must recycle the listed materials, such as cardboard packaging and contractors’ food and packaging waste, separately from other construction waste, and must not mix or compact them with it. The rules have applied since 31 March 2025, with micro-firms given until 31 March 2027.
Builders who move their own waste count as carriers under the duty of care. Each load of non-hazardous waste needs a transfer note kept for 2 years, and hazardous waste needs consignment notes and a register kept for 3 years. Site Waste Management Plans stopped being a legal requirement on 1 December 2013.
We arrange collections at offices, yards and depots: general waste, dry mixed recycling, cardboard, food and glass. Skips, muck-away and hazardous waste are outside what we arrange.

One site or many
A single project
A temporary supply, a site cabin and a few mobiles. We set up the supply contract and note when it needs to end.
Several live sites
Each site has its own supply, start and finish dates. We keep every meter and end date on one list so nothing runs on after the job.
Keeping contracts and documents in order
For each site and depot we record the following.
- Meter and supply contract for each temporary supply
- Planned disconnection date
- Office and depot energy end dates and notice windows
- Waste carrier details and transfer notes
- Insurance renewal dates
What to send us
Send what you have and we will ask for anything else we need.
- Site address, start date and expected finish
- Your connection offer or the network operator’s reference, if you have one
- Electricity and gas bills for offices and depots
- Your current insurance schedule, if you want a quote

Frequently asked questions
Who installs a temporary builders’ supply?
The network operator or an independent connection provider builds the connection. We arrange the supply contract and metering with an electricity supplier.
How long can a temporary supply stay in place?
It depends on the network operator and your connection offer. National Grid treats a temporary connection as one used for less than 5 years.
Is a site waste management plan still a legal requirement?
No. The Site Waste Management Plans Regulations 2008 were revoked from 1 December 2013. Check your planning conditions in case your council asks for one.
What does contractors’ all risks insurance cover?
Typically loss or damage to the works, tools and plant, owned or hired. We introduce you to FCA-authorised partner brokers, who arrange the cover.
