About Your Order:

Every Mercia pergola is a testament to sustainable elegance as it is crafted with precision right here in the UK, utilising sustainably sourced and rigorously regulated timber. The pergolas undergo a meticulous pressure-treatment process to ensure enduring beauty and structural integrity. It protects the timber from rot, decay, and the ravages of insects and also secures your peace of mind with a robust 15-year Anti-rot Guarantee. Please note to maintain this guarantee; the pergola will require waterproof treatment upon assembly and annually after that. Upon delivery, the structure must be constructed and positioned on a stable and level foundation.

Pergola Maintenance:

The Mercia Pergola is made from pressure-treated timbers for excellent durability and longevity. These products have an anti-rot solution in the timber structure, improving rot resistance. Mercia Garden Pressure Treated products come with a 15-year Anti-Rot guarantee. The manufacturer recommends that if you want to paint your garden pergola with a different colour, ensure the treatment you choose is recommended for pressure-treated timber.  The manufacturer requires the pergola to be treated with waterproofing upon construction. Applying a water-repellent product to your wooden garden bar is required for even more longevity and extra protection.

Booking Delivery

You will be required to book your delivery date at the time of placing your order (except for Metal Shed). Our 'Request a Delivery Date' service is available to the majority of areas and you'll find that the majority of the UK postcodes are FREE but some areas may incur a delivery surcharge and some postcodes are not covered at all. Select a 'requested delivery date' by entering your postcode in the 'Request a delivery date' section above. You will also be notified at this time if your area incurs a surcharge or delivery is not covered in your area.

Prior to Delivery

On the morning of your delivery date, you'll be sent an update by text with an estimated 2-hour delivery slot (this update can only be provided where a mobile number has been supplied on the billing address section at the time of checkout) together with a link to the manufacturer delivery portal where you'll be able to track your order.

Please note: Mercia Metal Sheds ONLY - your order is delivered by a courier you will not be notified prior to the delivery. If you are not in on the day of the delivery you will be carded and asked to contact the courier to arrange a new mutual delivery date. The estimated delivery lead time for Mercia's Metal sheds is identified on the product for the metal shed. Lead times are on working days (Monday - Friday) excludes Bank Holidays. These estimated lead times are provided by the manufacturer. Some remote areas will take a little longer.

Upon Delivery

Your order is delivered either kerbside or driveway and will be delivered on either a 3.5T, 7.5T or 18T Lorry. Unfortunately due to health and safety and insurance liabilities the driver will not be able to take your goods around to the back of your property but may upon request place the product at the side of the house if there are no access or restriction issues. We would not risk damaging your property whilst delivering a product to an unsafe location. Unfortunately, we will not be able to go through your property.

We would recommend against arranging for a third party to install the building before it's been delivered and checked that all parts are present, as we cannot be held liable for any third-party costs.

Pre-Painted Service - Shed Only

If you choose the Painting Service, the estimated delivery lead time will be approximately 28 working days (Monday to Friday, excluding weekends and Bank Holidays). Please note that if you select the Pick a Day option, the chosen delivery date will not apply. Instead, the delivery team will contact you to arrange a new delivery date for your painted shed.

Pre-Painted Service - Shed and Assembly

If you select the Painting Service and Assembly option, please review the section titled 'Orders with Assembly' below for details on the process and associated timelines.

Orders with Assembly 

The lead time for our installation option is around 7 weeks from the date of order. With the installation option, the majority of orders will have their delivery and installation on separate days; there will be a small number of orders which will have delivery and installation on the same day. You will be advised by the manufacturer's installation team which category your order falls into.

Depending on the installation option for your order, you will be contacted within the delivery timescale and given a date for either delivery/assembly on the same date or a separate date for delivery and assembly.
