How to choose between them
- Check the registration yourself. Gas Safe Register registration is a legal requirement for this work, and the register is public, so it takes a minute to confirm.
- 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.
