Sutton Council is set to spend almost £5million making a block of flats more environmentally friendly.

It will see a handful of leaseholders in the block hit with a hefty bill for the works. 

Some of the flats in Thicket Crescent have an energy efficiency rating of E, the fifth worst, or below.

The council and it’s housing provider, Sutton Housing Partnership (SHP), want to replace heating systems, roofing and windows at the block of 40 flats.

The block at 45 Thicket Crescent is home to 30 social tenants and 10 leaseholders – some of whom could have to pay £66,000 for the works.

A total of £4.8million has been budgeted for the project.

The estimated cost has risen from £3.3 million in December 2022 which is put down to rising costs in construction materials and labour.

The council has been awarded a grant of 1m Euros, around £880,000, for the works from Interreg Europe, a programme for energy efficiency works.

However, due to the increased costs the authority has applied to increase the grant to around £1.36million.

Those who own their flats in the block will have to pay a share of the cost of the upgrade.

The three leaseholders who bought their homes under Right to Buy in the past five years are expected to pay between £1,400 and £6,400.

The remaining seven leaseholders are expected to be charged for the major and fire safety works in the scheme, with the retrofit element covered by the grant. 

Despite this it still amounts to a £66,000 bill for the larger flats and £44,000 for the smaller flats.

A council report outlines that leaseholders who live in their flats will be offered up to two years interest free payments or 10 years to pay it back with interest.

Those on low income will have the option to take out a “voluntary legal charge” on the property meaning they make no payments and the debt it paid when the flat is sold.

The plans are set to be presented to the council’s housing economy and business committee on Tuesday (June 6). Committee chair Councillor David Bartolucci said: “The proposal to retrofit 45 Thicket Crescent, shows our continued commitment to ensuring our council housing is of the highest quality and goes towards meeting our net-zero climate target obligations.

“With these state of the art energy efficiency improvements, this will permanently reduce energy consumption, helping residents save money on their bills.

"The fact that this scheme has attracted substantial external grant funding to deliver this groundbreaking project shows that we are ahead of the game when delivering for our residents.”
