How to Challenge Unfair Leasehold Service Charges in the UK (Section 19 & 27A Guide)

Statutory Source: Landlord and Tenant Act 1985 (Sections 18–30) & LAFRA 2024

Quick Answer: How to Challenge Unfair Leasehold Service Charges in the UK (Section 19 & 27A Guide)

Under Section 19 of the Landlord and Tenant Act 1985, leasehold service charges in England and Wales are only legally payable to the extent that the costs were 'reasonably incurred' and the works or services are of a 'reasonable standard'. You can challenge excessive service charges by exercising your statutory right to inspect invoices under Sections 21 and 22, invoking the 18-month time-bar under Section 20B, enforcing the £250 cap on unconsulted major works under Section 20, or applying to the First-tier Tribunal (Property Chamber) under Section 27A.

Your 5 Statutory Weapons Against Excessive Service Charges (LTA 1985)

Sections 18 to 30 of the Landlord and Tenant Act 1985 provide leaseholders in England and Wales with five powerful statutory defences against inflated managing agent fees, phantom cleaning bills, and unconsulted roof/external repairs:

Statutory Section (LTA 1985)Legal Protection RuleThreshold / Time LimitLegal Outcome for the Leaseholder
Section 19(1)Costs must be 'reasonably incurred' & works of 'reasonable standard'Applies to every service charge itemFirst-tier Tribunal cuts excessive bills down to fair market price
Section 20Mandatory consultation for Major Works or Long-Term Agreements (QLTAs)>£250 per flat (works) or >£100/yr (contracts)Unconsulted major works capped strictly at £250 per leaseholder
Section 20BThe '18-Month Rule' against surprise historical balancing bills18 Months from when landlord incurred the costCosts incurred >18 months before demand/notice are 100% unrecoverable
Sections 21 & 22Statutory right to summary of accounts & inspection of receipts/invoicesLandlord must comply within 1 month of requestSummary criminal offence (up to £2,500 Level 4 fine) if agent refuses
Section 27A + s.20CApplication to First-tier Tribunal (Property Chamber) & Cost ShieldCan challenge past (if not agreed) or future billsBinding determination of payable sum + blocks landlord adding legal costs to bill

Step 1: Demand the Accounts & Original Invoices (Sections 21 & 22 LTA 1985)

Before paying a disputed balancing charge or filing a tribunal claim, serve a formal written request under Section 21 of the Landlord and Tenant Act 1985 requiring the landlord to provide a written summary of the relevant costs incurred in the last accounting year (certified by a qualified accountant where the building has more than 4 flats).

Once you receive the summary, you have 6 months under Section 22 to serve a second notice requiring the managing agent to provide reasonable facilities for you to inspect and copy the actual underlying contractor invoices, bank statements, and insurance policies free of charge. Under Section 25, failing to comply with a Section 21 or Section 22 notice without reasonable excuse is a criminal offence prosecutable by the local housing authority.

Never Admit or Agree the Charge Before Challenging at Tribunal!

Under Section 27A(4) of the Landlord and Tenant Act 1985, you CANNOT apply to the First-tier Tribunal to challenge a service charge if you have already 'agreed or admitted' it. Note that simply paying a service charge under protest (e.g. writing 'Paid Under Protest – Disputed' in your email to stop mortgage lender action) does NOT count as admitting it under Section 27A(5), allowing you to pay to protect your credit/lease and still sue for a refund at the Tribunal!

Step 2: Applying to the First-tier Tribunal (Section 27A & Section 20C)

If the managing agent refuses to reduce an unreasonable charge, any leaseholder (or group of leaseholders sharing the £110 application fee) can submit Form Leasehold 3 to the First-tier Tribunal (Property Chamber) under Section 27A of the 1985 Act:

• What You Need to Prove: Bring 2 or 3 alternative quotes from independent local contractors for the same cleaning, gardening, insurance, or repair specification, along with dated photographs showing poor workmanship.

• Always Tick 'Section 20C' & 'Paragraph 5A': On the Tribunal application form, always apply for an order under Section 20C of the 1985 Act (which stops the landlord from recharging their tribunal legal fees through the building's communal service charge) AND an order under Paragraph 5A of Schedule 11 to the Commonhold and Leasehold Reform Act 2002 (which stops the landlord billing their legal fees to you individually as an administration charge).

Leaseholder Service Charge Audit Checklist

Run this 5-point audit whenever your annual service charge demand arrives:

Step-by-Step Procedure:
Verify that the demand is accompanied by the mandatory statutory 'Summary of Tenants' Rights and Obligations (Service Charges)' under Section 21B—if missing, you have a statutory right to withhold payment until a compliant summary is served.
Check the dates the underlying works were carried out—disallow any item incurred more than 18 months ago where no Section 20B Notice was served.
Check the original Lease carefully—even if a cost is 'reasonable', you are not liable to pay for any service (such as a concierge or CCTV upgrade) that is not authorised by the service charge clause of your specific lease.
Verify whether any single repair project cost your flat more than £250 without a formal Stage 1 and Stage 2 Section 20 Consultation Notice.
If over 50% of the flats in your block are unhappy with the managing agent, exercise your statutory Right to Manage (RTM) to fire the managing agent and appoint your own.
