This technical update provides additional guidance on conservatories. It is important that all workmanship carried out during construction is completed in accordance with the relevant tolerances.
Where conservatories are constructed to a new build property, they may fall under cover of the warranty. Any subsequent defect found would most likely be exempt from building regulations but could result in a claim under the relevant policy.
Where it is intended by the developer to construct a conservatory at the same time as a feature of the completed dwelling, and is separated from the main dwelling accommodation by the house external wall with a permanent external door or combined window and door opening fitted, this will - on completion - be included under cover of the warranty, even though it is exempt from building regulations.
If the design plans show a conservatory provision and the reconstruction costs include for a conservatory, then the conservatory must also be included at completion to be able to sign off for warranty purposes.
In these circumstances we will check for the following:
If there is no apparent provision for a conservatory on the site plans, but between the Certificate of Approval and the Certificate of Insurance being issued a conservatory is proposed to be built at the request of the house purchaser, or foundations have been dug out for a conservatory and work is progressing but not completed when a completion inspection sign off is required for the main house, the risk management surveyor will not be able to sign off the house until the conservatory is completed.
Sun lounges (largely glazed annexes with solid roofs) or conservatories that are open through to the main dwelling with no provision of an external quality thermal door or window to separate the two areas thermally would not be exempt from the building regulations and are classed as extensions which must meet the requirements of both building regulations and the Premier Guarantee Technical Manual.
Risk management surveyors will be vigilant to any activity on site that may result in work that falls under warranty cover. Where it is noted that additional works that will or may include a conservatory are being added at the same time as the new house (even if the conservatory is not complete), warranty cover will extend to that conservatory. The developer must ensure the work meets the requirements of the technical manual as described above and is complete before the warranty surveyor is able to sign of the property.
If the surveyor is aware that ‘post completion’ a conservatory is to be built, notes will be made on the warranty site records to confirm that no conservatory existed at completion. If possible a photograph of the relevant elevation will also be taken for records.
