Energy eco project

I would like to find a local company (NN15) to quote for a 3-part job making our home more eco-friendly. We want to install solar panels on the roof, swap our gas boiler for a heat pump and install a charging point for an electric car. I’d like to work with one team rather than 3 and get advice on any grants available to cover the cost. Is this the kind of thing that can come as a package? Is there any cost savings to bundling the jobs together?
