Brilliant Rooflights

Having used a few Brett Martin Rooflights i have found them much easier than some other brands. the quality is brilliant and they look very good, especially the low profile dome. I would highly recommend.

COVID-19 - Important information about deliveries from our carrier Parcelforce

Our couriers have had to make some changes in order to protect you, and their staff, while also dealing with exceptionally high demand. As a result the following changes apply:

Parcelforce Worldwide Update - Coronavirus (COVID-19) Public Health England (PHE) has advised that people receiving parcels are not at risk of contracting the coronavirus (COVID-19). From experience with other coronaviruses, we know that these types of viruses don’t survive long on objects, such as letters or parcels. This complements the highly publicised guidance from PHE for people to wash their hands more often than usual using soap and hot water.

Changes to our delivery procedure in relation to signing for and receiving items in the UK

In order to protect both our people and customers as much as possible, we will not be handing over our hand-held devices to customers to capture electronic signatures. Our drivers will instead log the first and last name of the person accepting the item and we will record the geolocation of the delivery. This will apply to all deliveries that normally require a signature.
If recipients are unable to come to the door or are self-isolating, we will post a customer contact card in the normal way, advising of other ways the recipient can arrange to get their item. For example, by getting a friend or family member (who is not resident with someone who is self-isolating) to collect the parcel from their local Parcelforce depot or Post Office branch, as specified on the card. They will need to bring along the card we left and a form of ID in the name of the person the item is addressed to. Examples of suitable ID are specified on the card.

Suspension of UK service guarantee

Due to the current situation, there are significant impacts on our ability to maintain all our usual service levels. We will continue offering our services, receiving and delivering parcels for our customers but there may be disruptions to some services under current conditions. As a result, we will be suspending service guarantees from 18 March 2020 but will seek to ensure ‘all reasonable endeavours’ to maintain service levels where we can.
