THE SIG APPROACH

Organised from start to finish.

See your electricity savings

Compare how much power your existing lights use with the LEDs that would replace them. Add your operating hours and electricity price to see the estimated yearly saving.

A bespoke installation quote

Every LED upgrade is priced individually around your fittings, access, any access equipment needed, waste removal and installation scope. A site survey helps us agree a practical plan.

We work out the upgrade price

You do not need to guess an installation cost. Use the calculator to explore electricity savings, then request a bespoke quote for supplying and fitting the right LEDs.

LED SAVINGS CALCULATOR

How much could you save on electricity?

Compare the lights you have now with the LEDs you could replace them with. We use the difference in power, how long the lights are on and your electricity rate to estimate the saving.

Example: a 58W fluorescent tube can be compared with a 20W LED reference replacement, saving 38W per tube while switched on. The figures below are examples to change, not a lighting specification or an installation quote. If you are unsure about your lights, ask us for a survey and bespoke quote ↗.

1. Your lights now

What type of lights do you have?How many lights are you replacing?For tubes, count each tube, including two tubes in a twin fitting.Power used by each existing light (watts)For fluorescent tubes, use the wattage printed on each tube, such as 18W, 36W or 58W.

2. Our suggested LED replacement

Suggested LED power (watts)We suggest a reference LED wattage for supported fluorescent tubes. Final brightness and suitability are checked during a survey.

3. How you use your lighting

Hours the lights are on each dayExample: 10 hours during a working day.Days the lights are on each yearExample: 250 working days per year.

4. Your electricity

Don't know your rate? We use a UK business average benchmark of 24.51p/kWh (April–June 2026, including Climate Change Levy). Government source ↗. Your actual bill rate gives a better estimate.

A FEW THINGS YOU MIGHT ASK

Good to know.

Are the calculator results an installation quote?

No. LED upgrades are quoted individually. The calculator shows potential electricity savings from your lighting details. There is no installation-cost field; we provide a bespoke quote after reviewing the work.

How are future savings estimated?

Choose 1–10 years. We use your electricity details if supplied, or a dated UK business average with no assumed price change. Fixed rates stay unchanged until expiry. Future changes are adjustable scenarios, not forecasts. Installation costs are quoted separately.
