What is retrofit?

Most British homes are too hot in the summer and  cripplingly expensive to heat in the winter. The solution is retrofit.

Retrofit can involve improving your energy efficiency through better insulation, glass and glazing, temperature controls, draught proofing, LEDs, lighting controls and more. 

Retrofit can also involve improving your energy sources with boiler upgrades, heat pumps or renewables like solar. 

We  understand the barriers  to retrofit your portfolio...

I know I need to retrofit my portfolio, but I don't know where to start

I can't seem to find the right tradespeople

What's going to be the impact on my valuation and returns?

It might be too expensive. I don't know if I can afford it
