How installation companies (insulation, lifts, shutters and similar) file

Installation companies (insulation, lifts, shutters, solar and similar) often buy stock and equipment up front, so stock at the year end and capital allowances both affect the tax bill.

Every company on these pages is an active private limited company that files small or micro-entity accounts. Each one has to deliver accounts to Companies House within 9 months of its year end, pay corporation tax 9 months and 1 day after it, and file a CT600 with HMRC within 12 months.
