|---|---|---|

| Life expectancy | Can last another 60-100 years with fundamental maintenance. | Modern units frequently need replacement after 20-25 years. |
| Energy Efficiency | Can achieve considerable heat retention with draught-proofing. | Exceptional thermal properties, however typically at the expense of visual appeals. |
| Planning Permission | Typically not required (unless in particular listed cases). | Frequently needed in Conservation Areas; restricted for Listed Buildings. |
