Section 20 Consultation for London Landlords — What It Is and When It Applies
If you own a leasehold property in London or manage a block of flats, Section 20 consultation is a mandatory process before carrying out major works or entering long-term service contracts. Getting it wrong exposes you to significant financial penalties.
What Is Section 20?
Section 20 of the Landlord and Tenant Act 1985 (as amended by the Commonhold and Leasehold Reform Act 2002) requires landlords and freeholders to consult with leaseholders before:
- Carrying out qualifying works where any leaseholder's contribution would exceed £250
- Entering into a qualifying long-term agreement (service contract) for more than 12 months
In practice, any significant communal maintenance works in a London leasehold block — roof replacement, lift repairs, external decoration, boiler replacement for a communal system — will trigger Section 20 consultation.
The Three-Stage Consultation Process
Stage 1: Notice of Intention (NOI)
The freeholder or managing agent must serve a written Notice of Intention on all qualifying leaseholders and any recognised tenants association. The notice must:
- Describe the intended works
- State why the works are considered necessary
- Invite leaseholder observations within 30 days
- Invite leaseholders to nominate a contractor to be included in any tender process (within 30 days)
Stage 2: Notice of Estimates
After obtaining at least two estimates (including any nominee contractor's estimate), serve a second notice showing all estimates and any observations received at Stage 1. Leaseholders have 30 days to make further observations.
Stage 3: Notice of Award (if applicable)
If the chosen contractor is not the lowest tender, the freeholder must serve a Notice of Award explaining why, within 21 days of entering the contract.
Penalties for Non-Compliance
If Section 20 consultation is not carried out correctly, the freeholder can only recover £250 per leaseholder for the qualifying works, regardless of the actual cost. On a major roof replacement costing £80,000 across 20 flats, this could mean recovering only £5,000 instead of £80,000 — a severe penalty.
Common Mistakes
- Starting works before the 30-day observation period has elapsed
- Not serving notice on a recognised tenants association if one exists
- Failing to obtain the minimum two estimates
- Not including a nominated contractor's estimate if one was submitted
- Undertaking multiple smaller jobs to avoid the £250 threshold (this is aggregation — courts have held that related works should be treated as a single project)
Frequently asked questions
Does Section 20 apply to all landlords in London?
Section 20 applies to freeholders and landlords of leasehold properties (blocks of flats, maisonettes etc.) where the property is held on a lease. It does not apply to standard assured shorthold tenancies of entire houses or flats. If you own the freehold to a block of flats with leaseholders, Section 20 applies to any significant communal works.
What is the £250 threshold in Section 20?
The threshold is £250 per qualifying leaseholder. If works cost enough that any one leaseholder would contribute more than £250 (based on their service charge apportionment), Section 20 consultation is triggered. In London blocks with high service charges, this threshold is reached on most significant maintenance jobs.
Can I carry out emergency works without going through Section 20?
Yes — there is a dispensation process for genuine emergencies. If works are urgently required to prevent serious damage or a safety risk, the freeholder can carry out works without completing the consultation process and then apply to the First-tier Tribunal (Property Chamber) for dispensation. The Tribunal will grant dispensation if the emergency was genuine and leaseholders were not materially prejudiced.
How long does Section 20 consultation take in London?
The minimum statutory process takes around 70 days — 30 days for Stage 1 observations, time to obtain estimates, then 30 days for Stage 2 observations. In practice, with tribunal involvement or complex leaseholder responses, the process often takes 3-6 months. Factor this into your maintenance planning timeline.
