How to choose between them
- Check the registration yourself. Trade body memberships are public, and each body's own register confirms them in a minute.
- Get three quotes on the same specification. Written down, split into labour, materials and anything structural. Most people compare a total against a total and end up choosing between two different jobs.
- Ask what is not included. Making good, waste removal, scaffolding and VAT are the four that turn a cheap quote into an average one.
- Never pay a large deposit up front. Materials in advance is normal. Half the total before anyone turns up is not.

Window and door fitters in Glasgow: common questions
Why does FENSA registration matter?
Replacement windows must meet building regulations for thermal performance. A FENSA registered installer self-certifies and sends you a certificate. An unregistered one means you need a building control application, and no certificate is a problem when you sell.
