How can I find a reliable composite door installer

[old wrinkly]

I want to replace my old UPVC porch door with a composite door.

I have seen a few designs but a number of the sites only do a "supply only" service.

Anyone offer any guidance on how I can find a reliable composite door installer in the Colchester, Essex area who could provide a quote if I choose to buy my door from one of these "supply only" companies.

Thanks

We bought an aluminium door which was suppy onla and I asked a local joiner to fit the door. He could then also fit some matching trims to blend it into the doorway. There is no magic to fitting them. Make sure you or your fitter foam out all the gaps to the brickwork to avoind drafty cold spots.
