Common questions

Before you read them.

Who do you deliver this work for?

Homeowners, landlords, businesses, housing associations and councils, and main contractors who need a package delivered inside a wider programme. Each case study is tagged with who it was delivered for, so the Delivered for filter above shows you the ones like yours.

Where do you work?

Our head office is in Clitheroe, Lancashire, with offices in Manchester and London. Domestic solar and battery work centres on Lancashire, Cumbria, Greater Manchester and Cheshire. Retrofit programmes for councils and housing providers run across the UK, including County Durham, North Yorkshire, West Yorkshire and Staffordshire.

What standards is the work delivered to?

Flat roof insulation is delivered under our PAS 2030 certification as a TrustMark registered installer. Whole house retrofit programmes are assessed and coordinated in house to PAS 2035, with a named Retrofit Coordinator, Designer and Assessor. Every certificate is listed on our accreditations page with its scope.

Are the savings and generation figures real?

They are estimates, and we say so. Generation and self sufficiency come from the performance estimate in the quote; bill savings carry the tariff, usage and price growth assumptions they were built on; programme outcomes such as EPC bands come from delivery records. Each case study has a notes section that says where every figure came from.

Fancy being the next one on here?

If you have a re roof, an extension or a rising electricity bill in Lancashire, Cumbria or anywhere across the North West, that is the moment to have the conversation. Survey first, figures second, no pressure either way. If you run housing stock, or a programme that needs a delivery partner, it is the same conversation with a longer spreadsheet.
