The construction of a new multi-storey car park for patients, staff, and visitors at Watford General Hospital is underway.

The car park, which will include 1,455 spaces, is being built by the current hospital on land which was formerly part of the Farm Terrace Allotments.

West Hertfordshire Hospitals NHS Trust says the facility will "significantly improve" access to the hospital, taking away the current issue of walking up and down a steep slope.

There will be an enclosed walkway providing level access from the car park to the hospital, the latter of which is also set to undergo a huge redevelopment.

At the end of May, the trust submitted plans to rebuild Watford General, with capital funding expected from the Government.

Redevelopment of Watford General, subject to approval, is unlikely to be ready until at least 2025 but the multi-storey car park is scheduled to open in spring 2022.

Once completed, 1,290 of the 1,455 spaces will be for hospital use, and the car park will be equipped with lifts and stairs, and provide access to wheelchairs to support those with restricted mobility.

The trust says providing modern, accessible and safe car parking facilities at Watford General Hospital is a "long-held goal".

The multi-storey will provide 72 disabled parking bays, almost doubling the total currently available, while there will be charging points for electric vehicles.

There will also be around 400 more spaces at the hospital outside of the multi-storey.

West Hertfordshire Hospitals NHS Trust says it has not finalised plans for charging car park users yet but it says it is committed to reviewing charges and keeping charges "as low as possible", whilst covering the operating costs of the car park.

The new car park will utilise modern technology to enable much more flexible charging and payment options and make entry and exit from the multi-storey quick and easy.

Whilst the actual system has still to be finalised, the trust intends to adopt the principle of payment on exit and provide a range of flexible payment options. Currently, visitors pay on entry to the hospital.

The total capital cost for the new facility is £39.2m and the car park is being funded through public dividend capital provided by Her Majesty’s Treasury.

The new car park will be constructed using public finance and once built, it will be owned by the trust.

This year, the trust will tender for a company to manage the multi-storey along with the rest of its car parks in St Albans and Hemel Hempstead.
