Fixed vs Variable Service Charge 2026: What Leaseholders Need to Know
Almost every leasehold flat comes with a service charge to cover the upkeep of the building and shared areas, but leases split into two very different models: a fixed amount you can budget around, or a variable charge tied to what the building actually spends. Knowing which one you are signing up for -- and what rights you have if it feels unfair -- matters as much as the headline figure. This guide compares the two for 2026.
TL;DR -- 30-Second Summary
- • Fixed charge: a set annual amount, sometimes RPI-linked, giving budgeting certainty
- • Variable charge: your share of actual costs, reconciled after the year end -- more common, especially in larger blocks
- • Section 20 consultation is required for major works above roughly GBP 250 per leaseholder
- • You can challenge unreasonable charges at the First-tier Tribunal (Property Chamber)
- • Leasehold and Freehold Reform Act 2024 aims to improve transparency, but implementation is phased and not all measures are yet in force
Side-by-Side Comparison
| Feature | Fixed service charge | Variable service charge |
|---|---|---|
| How it is set | Fixed amount in the lease, sometimes RPI-linked | Proportionate share of actual costs, reconciled annually |
| Budgeting certainty | High -- known in advance | Lower -- can vary year to year |
| Risk of cost overruns | Borne by freeholder/managing agent | Borne by leaseholders directly |
| Typical setting | Smaller developments, simpler buildings | Larger blocks, lifts, communal heating, concierge |
| Major works | May still require a separate charge outside the fixed sum | Charged in year incurred; Section 20 applies above thresholds |
| Right to challenge | First-tier Tribunal (Property Chamber) for both types | |
Worked Example: A Block of 20 Flats
Consider a block of 20 equally sized flats. Under a fixed lease, each leaseholder pays GBP 1,800 a year regardless of actual spend. Under a variable lease, each leaseholder pays a 1/20th share of whatever the block actually spends, reconciled after the year end.
| Scenario | Fixed charge per flat | Variable charge per flat |
|---|---|---|
| Normal year (block spends GBP 34,000) | GBP 1,800 | GBP 1,700 |
| Low-cost year (block spends GBP 28,000) | GBP 1,800 (overpaying by GBP 400) | GBP 1,400 |
| Major works year (roof replacement, GBP 100,000 total) | GBP 1,800 base charge; major works often billed separately regardless | GBP 5,000 individual share -- triggers a Section 20 consultation |
In a normal or low-cost year, the fixed-charge leaseholder pays a predictable amount but may quietly overpay compared with actual costs. In a major works year, the variable-charge leaseholder's individual contribution of GBP 5,000 comfortably exceeds the roughly GBP 250 threshold, meaning the landlord must run a formal Section 20 consultation, including at least two estimates and an opportunity to comment, before the works can proceed and be charged.
When a Fixed Service Charge Wins
A fixed charge suits buyers who value budgeting certainty above all else -- for example first-time buyers stretching their mortgage affordability who cannot absorb an unexpected spike in costs, or anyone who prefers a predictable monthly outgoing over the risk of a large reconciliation bill after the fact.
It also suits leaseholders in smaller, simpler buildings where running costs genuinely do not vary much year to year, so the fixed amount is unlikely to significantly overstate or understate real costs over time.
When a Variable Service Charge Wins
A variable charge suits buyers who are comfortable with some year-to-year fluctuation and want to pay only for what is actually spent, without a margin built in to cover the freeholder's risk. Over the long run, well-managed buildings with efficient service providers can end up cheaper under a variable arrangement than an equivalent fixed one.
It also gives leaseholders more direct oversight, since actual accounts are reconciled and can be requested, and gives more leverage to challenge specific costs at the Tribunal if a managing agent is not delivering value for money -- something a fixed charge, by design, offers less visibility into.
