How to choose between them
A whole-home job in Penzance typically runs £2,700 to £8,100 (local cost factor 0.9×), so the spread between three quotes on the same brief is worth chasing. Regency and Victorian seafront terraces along Chapel Street, Georgian townhouses around the harbour, plus Edwardian villas in Alverton and interwar bungalows in Heamoor.
Heritage note: Around 15 conservation areas across west Cornwall including Chapel Street and St Ives.
Whichever company you approach: get three written, itemised quotes, confirm FENSA or CERTASS registration on the scheme's own register, check the guarantee is insurance-backed, and ask for two recent local installs you can look at. Our guide to comparing double glazing quotes walks through it.
