Commercial Solar Panels & Battery Storage in Great Dunmow

For a Great Dunmow business, commercial rooftop solar typically works out at roughly £700-£900 per kWp installed, so a mid-sized 50kWp array on a Chelmsford Road or Ongar Road industrial unit generally lands in the region of £35,000-£45,000 before tax relief. With 100% Annual Investment Allowance available on qualifying plant and commercial power at around 22-27p/kWh, most Great Dunmow installs pay back within three to six years. Every quote follows a free on-site survey so the figure reflects your actual roof, load profile and half-hourly usage.

For most commercial buildings on Great Dunmow's industrial estates — Chelmsford Road, Ongar Road, Station Road and Oak Industrial Park — a rooftop solar array falls under permitted development and needs no planning application. The main exception is properties within the Great Dunmow Conservation Area (the historic High Street, Market Place and Doctors Pond core, with its 170-plus listed buildings) or any listed building, where heritage constraints apply. Uttlesford District Council is the local planning authority, and we confirm the permitted-development position for your specific CM6 site as part of the survey.

The distribution network operator for Great Dunmow and the whole CM6 area is UK Power Networks (UKPN). We handle the G98 or G99 connection application to UKPN on your behalf — G98 for smaller systems and G99 for larger commercial arrays — so your Great Dunmow installation is fully compliant and correctly notified before it's energised.

A typical commercial rooftop install on a Great Dunmow industrial unit takes around one to three weeks on site, depending on system size, roof type and whether battery storage or EV charging is included. Larger arrays on the bigger Chelmsford Road or Ongar Road warehouses can run longer. We schedule around your operating hours to keep disruption to your Great Dunmow business to a minimum, and the UKPN paperwork runs in parallel.

The main financial lever for Great Dunmow businesses is the 100% Annual Investment Allowance, which lets you deduct the full cost of qualifying solar and battery plant (up to £1M) against taxable profits in year one. Exported power can also earn income through a Smart Export Guarantee tariff. Locally, Uttlesford District Council's Zero Carbon Communities Grant supports community and organisation-led carbon-reduction projects across CM6, and we help you factor the available reliefs into your payback case.

Most Great Dunmow commercial solar projects pay back within three to six years. The town's East-of-England irradiance of roughly 1,250-1,320 kWh/m², combined with commercial electricity at around 22-27p/kWh and 100% AIA tax relief, drives a strong return — particularly for daytime-load occupiers like the light-industrial, trade-counter and motor-trade businesses on the Chelmsford Road and Ongar Road estates. Adding battery storage can further improve the return by shifting cheap or self-generated power into peak periods.

Yes. Battery storage is a strong fit for Great Dunmow's industrial and trade occupiers, letting you store surplus daytime solar generation for use in the evening or during peak-rate periods, and providing resilience for sites on the A120 corridor. We size the battery to your Great Dunmow site's load profile alongside the solar array, and it connects under the same UKPN G98/G99 process.

We cover the whole CM6 area and the wider 30-mile radius from our Sawbridgeworth base, including Great Dunmow's Chelmsford Road, Ongar Road, Station Road and Oak Industrial Park estates plus surrounding villages such as Felsted, Thaxted, Little Canfield, Great Easton, Barnston, Stebbing and Flitch Green. Nearby towns we also serve include Bishop's Stortford, Stansted, Braintree, Chelmsford and Saffron Walden.
