Local notes
Homes in St Albans.
- The city has a mix of period and modern homes, so the right boiler, flue route and pipework differ from street to street. That is why we survey before we price.
- Some streets fall inside conservation areas, which can add siting rules for outdoor air-conditioning units. We confirm what applies at the survey.

Does air conditioning need planning permission in St Albans?
Usually not. Most houses can have an outdoor unit under permitted development, provided size and siting conditions are met. Exceptions include flats and maisonettes, listed buildings and conservation areas, where extra rules apply. We confirm which applies at the survey, before you commit, so nothing comes as a surprise later.
Do you do landlord gas safety certificates in St Albans?
We cover landlord gas safety compliance, including the annual CP12 Landlord Gas Safety Record. The law requires one for any let property with gas appliances, carried out by a Gas Safe registered engineer, with a copy given to tenants within 28 days of the check. Book through our contact page.
