Living at Gateway House

How to pay, who to call and what to do — for leaseholders, tenants and anyone selling or letting a flat.

Emergencies

If something is dangerous, call 999 first

Fire, a smell of gas, or someone at risk: dial 999. Then let the managing agent know.

Give the building's address as Gateway House, 322 Regents Park Road, London N3 2FH, or the what3words location ///stocks.less.clever.

Service charges

What you pay and what it covers

The service charge funds everything shared: buildings insurance, cleaning, communal electricity, lift maintenance and inspection, fire-safety systems, grounds, repairs, the managing agent's fee and a contribution to the reserve fund for future major works. Your flat's share is fixed by the percentage in your lease.

Demands are issued in advance with a summary of your rights and obligations, as the law requires. Payment is due on the date shown on the demand. Late payment adds cost to everyone, so if you are struggling, contact the agent early — a payment plan is usually possible.

How to pay

  • Online through the owners’ portal — refer to Sterling Estates Management for your log-in details
  • Bank transfer to the client account shown on your demand (quote your flat reference)
  • Standing order — ask the agent for a mandate

More information about your service charge, your account or a payment plan can be obtained from Sterling Estates Management: sterlingestates.uk, 020 8427 3363 or info@sterlingestates.org.uk.

Repairs

Reporting a repair

The RTM company is responsible for the structure, roof, external walls, window frames, communal hallways, stairs, lifts, doors, lighting, bin stores, car park and grounds. Anything inside your flat — including internal pipework, boiler, your front door lock and glazing — is yours to maintain, unless your lease says otherwise.

To report a communal problem, email contact@gatewayhousertm.co.uk or use the portal. Include:

  • Where it is (floor, core, nearest flat number)
  • What's wrong and since when
  • A photo if you can
  • Whether it's a safety risk

You'll get a reference. Urgent items (lift out, door not securing, lighting failure on a stair) are prioritised the same day.

Fire safety

Keep the escape routes clear

A fire risk assessment of the common parts is carried out by a competent assessor and reviewed regularly; a copy can be requested. Residents can help most by following three rules:

  • Nothing in the hallways or stairs. No prams, bikes, shoes, mats or plants. They're escape routes and they get cleared without notice.
  • Don't prop open fire doors. Flat front doors and corridor doors are fire doors — they must self-close. Tell the agent if yours doesn't.
  • No charging of e-bikes or e-scooters in common parts.

The evacuation policy for the building is set out in the fire risk assessment. Make sure everyone in your household — and any tenants — knows it.

Please read the property updates issued by Sterling Estates Management: they include fire safety information and any changes to arrangements in the building.

Selling, remortgaging or letting

What your solicitor will ask for

Your buyer's solicitor will request a leasehold management pack (the LPE1 form) covering service charges, insurance, accounts, major works and any disputes. The managing agent prepares it; there is a fee, and it can take up to 15 working days, so order it early.

On completion, the new owner must serve notice of transfer on the RTM company (via the agent) so the service charge account is moved. Most leases also require a notice of any mortgage and of any sub-letting.

Letting your flat

Check your lease for any restriction on sub-letting. Give the agent your tenants' names and your own correspondence address — service charge demands still come to you, the leaseholder, and you remain responsible for your tenants' compliance with the lease.

Can't find what you need?

The managing agent is the quickest route for anything about your flat or your account. The director is happy to hear from you too.
