Band C to D on a typical new apartment; the council sets the band after completion.

What goes into the monthly figure

The mortgage payment plus the three charges that come with a leasehold home.

Service charge
Your share of running the building: buildings insurance, cleaning and lighting of shared areas, the lift, grounds, a concierge or gym if there is one, and a reserve fund for the roof and major works. Developers quote an estimate; it usually rises once the building is occupied and real bills arrive.
Ground rent
Rent paid to the freeholder for the land. The Leasehold Reform (Ground Rent) Act 2022 set it at a peppercorn (nothing) on all new residential leases from 30 June 2022, so on a new build it should be nil. Older leases and resales can still carry one.
Council tax
Set by band, and a new home is banded by the Valuation Office after completion, so the developer can only estimate it. Band C or D is typical for a two-bedroom new apartment outside London; single occupants get 25% off.

Questions people ask

Do houses have these charges too?

Most new houses are freehold with no ground rent, but many developments charge an estate management fee for private roads, green space and drainage that the council has not adopted. Ask the developer and enter it in the service charge line.

Can the service charge go up?

Yes. It is set each year from the actual and budgeted costs of the building, and first-year estimates on new developments are often low. Ask for the budget, the reserve fund policy and who manages the building before you reserve.

Does the service charge affect my mortgage?

Lenders include it in their affordability check, so a high charge lowers what they will lend. Some also decline flats with escalating ground rents or very short leases; a peppercorn rent and a long lease on a new build avoid both.
