Marshall Clean Heat and Power Ltd

Lead times for North Yorkshire renewables installers swing seasonally — late spring and early summer are peak demand. At time of indexing the public Google listing showed 23 reviews at 4.2★, which gives some indication of throughput. Ask Marshall Clean Heat and Power Ltd directly for current scheduling once you've got a written quote. Plan for 4–12 weeks from deposit to install on a typical residential project; complex roofs or DNO upgrades can extend that.

Search 'find-and-update.company-information.service.gov.uk' for the trading name. Look at incorporation date, current status (Active vs Liquidation/Dissolved), most recent accounts filing, and director list. A long-trading limited company with up-to-date accounts is a safer signal than a recently incorporated firm.

RECC (Renewable Energy Consumer Code) and HIES (Home Insulation & Energy Systems) are the two main consumer protection codes for UK renewables installers. Check the RECC register at recc.org.uk or HIES register at hies.co.uk by company name. Membership of either gives you escalation routes and deposit protection.

An IBG is essential — it covers the workmanship warranty if the installer ceases trading. MCS-certified installers usually offer IBG via the MCS scheme. Confirm Marshall Clean Heat and Power Ltd provides an IBG certificate at handover; don't accept a workmanship guarantee that's only as good as the installer's continued existence.

Most reputable UK installers — including most York-area firms — offer a free desktop survey followed by a paid or no-cost roof inspection. Marshall Clean Heat and Power Ltd's specific policy isn't published on EnergyRanked; ask when you make initial contact (their website marshallenergy.co.uk is a useful starting point). A red flag would be any installer quoting without ever physically seeing the roof or property.
